@@ -0,0 +1,674 @@ + GNU GENERAL PUBLIC LICENSE + Version 3, 29 June 2007 + + Copyright (C) 2007 Free Software Foundation, Inc. + Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + + Preamble + + The GNU General Public License is a free, copyleft license for +software and other kinds of works. + + The licenses for most software and other practical works are designed +to take away your freedom to share and change the works. By contrast, +the GNU General Public License is intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains free +software for all its users. We, the Free Software Foundation, use the +GNU General Public License for most of our software; it applies also to +any other work released this way by its authors. You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + + To protect your rights, we need to prevent others from denying you +these rights or asking you to surrender the rights. Therefore, you have +certain responsibilities if you distribute copies of the software, or if +you modify it: responsibilities to respect the freedom of others. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received. You must make sure that they, too, receive +or can get the source code. And you must show them these terms so they +know their rights. + + Developers that use the GNU GPL protect your rights with two steps: +(1) assert copyright on the software, and (2) offer you this License +giving you legal permission to copy, distribute and/or modify it. + + For the developers' and authors' protection, the GPL clearly explains +that there is no warranty for this free software. For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + + Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the manufacturer +can do so. This is fundamentally incompatible with the aim of +protecting users' freedom to change the software. The systematic +pattern of such abuse occurs in the area of products for individuals to +use, which is precisely where it is most unacceptable. Therefore, we +have designed this version of the GPL to prohibit the practice for those +products. If such problems arise substantially in other domains, we +stand ready to extend this provision to those domains in future versions +of the GPL, as needed to protect the freedom of users. + + Finally, every program is threatened constantly by software patents. +States should not allow patents to restrict development and use of +software on general-purpose computers, but in those that do, we wish to +avoid the special danger that patents applied to a free program could +make it effectively proprietary. To prevent this, the GPL assures that +patents cannot be used to render the program non-free. + + The precise terms and conditions for copying, distribution and +modification follow. + + TERMS AND CONDITIONS + + 0. Definitions. + + "This License" refers to version 3 of the GNU General Public License. + + "Copyright" also means copyright-like laws that apply to other kinds of +works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this +License. Each licensee is addressed as "you". "Licensees" and +"recipients" may be individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of an +exact copy. The resulting work is called a "modified version" of the +earlier work or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work based +on the Program. + + To "propagate" a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + + To "convey" a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user through +a computer network, with no transfer of a copy, is not conveying. + + An interactive user interface displays "Appropriate Legal Notices" +to the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work +for making modifications to it. "Object code" means any non-source +form of a work. + + A "Standard Interface" means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + + The "System Libraries" of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +"Major Component", in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + + The Corresponding Source need not include anything that users +can regenerate automatically from other parts of the Corresponding +Source. + + The Corresponding Source for a work in source code form is that +same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + + You may make, run and propagate covered works that you do not +convey, without conditions so long as your license otherwise remains +in force. You may convey covered works to others for the sole purpose +of having them make modifications exclusively for you, or provide you +with facilities for running those works, provided that you comply with +the terms of this License in conveying all material for which you do +not control copyright. Those thus making or running the covered works +for you must do so exclusively on your behalf, under your direction +and control, on terms that prohibit them from making any copies of +your copyrighted material outside their relationship with you. + + Conveying under any other circumstances is permitted solely under +the conditions stated below. Sublicensing is not allowed; section 10 +makes it unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + + When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such circumvention +is effected by exercising rights under this License with respect to +the covered work, and you disclaim any intention to limit operation or +modification of the work as a means of enforcing, against the work's +users, your or third parties' legal rights to forbid circumvention of +technological measures. + + 4. Conveying Verbatim Copies. + + You may convey verbatim copies of the Program's source code as you +receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these conditions: + + a) The work must carry prominent notices stating that you modified + it, and giving a relevant date. + + b) The work must carry prominent notices stating that it is + released under this License and any conditions added under section + 7. This requirement modifies the requirement in section 4 to + "keep intact all notices". + + c) You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable section 7 + additional terms, to the whole of the work, and all its parts, + regardless of how they are packaged. This License gives no + permission to license the work in any other way, but it does not + invalidate such permission if you have separately received it. + + d) If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has interactive + interfaces that do not display Appropriate Legal Notices, your + work need not make them do so. + + A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +"aggregate" if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms +of sections 4 and 5, provided that you also convey the +machine-readable Corresponding Source under the terms of this License, +in one of these ways: + + a) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for as + long as you offer spare parts or customer support for that product + model, to give anyone who possesses the object code either (1) a + copy of the Corresponding Source for all the software in the + product that is covered by this License, on a durable physical + medium customarily used for software interchange, for a price no + more than your reasonable cost of physically performing this + conveying of source, or (2) access to copy the + Corresponding Source from a network server at no charge. + + c) Convey individual copies of the object code with a copy of the + written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, and + only if you received the object code with such an offer, in accord + with subsection 6b. + + d) Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access to the + Corresponding Source in the same way through the same place at no + further charge. You need not require recipients to copy the + Corresponding Source along with the object code. If the place to + copy the object code is a network server, the Corresponding Source + may be on a different server (operated by you or a third party) + that supports equivalent copying facilities, provided you maintain + clear directions next to the object code saying where to find the + Corresponding Source. Regardless of what server hosts the + Corresponding Source, you remain obligated to ensure that it is + available for as long as needed to satisfy these requirements. + + e) Convey the object code using peer-to-peer transmission, provided + you inform other peers where the object code and Corresponding + Source of the work are being offered to the general public at no + charge under subsection 6d. + + A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means any +tangible personal property which is normally used for personal, family, +or household purposes, or (2) anything designed or sold for incorporation +into a dwelling. In determining whether a product is a consumer product, +doubtful cases shall be resolved in favor of coverage. For a particular +product received by a particular user, "normally used" refers to a +typical or common use of that class of product, regardless of the status +of the particular user or of the way in which the particular user +actually uses, or expects or is expected to use, the product. A product +is a consumer product regardless of whether the product has substantial +commercial, industrial or non-consumer uses, unless such uses represent +the only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, +procedures, authorization keys, or other information required to install +and execute modified versions of a covered work in that User Product from +a modified version of its Corresponding Source. The information must +suffice to ensure that the continued functioning of the modified object +code is in no case prevented or interfered with solely because +modification has been made. + + If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + + The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or updates +for a work that has been modified or installed by the recipient, or for +the User Product in which it has been modified or installed. Access to a +network may be denied when the modification itself materially and +adversely affects the operation of the network or violates the rules and +protocols for communication across the network. + + Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + + When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders of +that material) supplement the terms of this License with terms: + + a) Disclaiming warranty or limiting liability differently from the + terms of sections 15 and 16 of this License; or + + b) Requiring preservation of specified reasonable legal notices or + author attributions in that material or in the Appropriate Legal + Notices displayed by works containing it; or + + c) Prohibiting misrepresentation of the origin of that material, or + requiring that modified versions of such material be marked in + reasonable ways as different from the original version; or + + d) Limiting the use for publicity purposes of names of licensors or + authors of the material; or + + e) Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f) Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified versions of + it) with contractual assumptions of liability to the recipient, for + any liability that these contractual assumptions directly impose on + those licensors and authors. + + All other non-permissive additional terms are considered "further +restrictions" within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + + If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; +the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + + However, if you cease all violation of this License, then your +license from a particular copyright holder is reinstated (a) +provisionally, unless and until the copyright holder explicitly and +finally terminates your license, and (b) permanently, if the copyright +holder fails to notify you of the violation by some reasonable means +prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + + Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or +run a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + + An "entity transaction" is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + + You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's "contributor version". + + A contributor's "essential patent claims" are all patent claims +owned or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, "control" includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + + Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + + In the following three paragraphs, a "patent license" is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To "grant" such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + + If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. "Knowingly relying" means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + + A patent license is "discriminatory" if it does not include within +the scope of its coverage, prohibits the exercise of, or is +conditioned on the non-exercise of one or more of the rights that are +specifically granted under this License. You may not convey a covered +work if you are a party to an arrangement with a third party that is +in the business of distributing software, under which you make payment +to the third party based on the extent of your activity of conveying +the work, and under which the third party grants, to any of the +parties who would receive the covered work from you, a discriminatory +patent license (a) in connection with copies of the covered work +conveyed by you (or copies made from those copies), or (b) primarily +for and in connection with specific products or compilations that +contain the covered work, unless you entered into that arrangement, +or that patent license was granted, prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot convey a +covered work so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you may +not convey it at all. For example, if you agree to terms that obligate you +to collect a royalty for further conveying from those to whom you convey +the Program, the only way you could satisfy both those terms and this +License would be to refrain entirely from conveying the Program. + + 13. Use with the GNU Affero General Public License. + + Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU Affero General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the special requirements of the GNU Affero General Public License, +section 13, concerning interaction through a network will apply to the +combination as such. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of +the GNU General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + + Each version is given a distinguishing version number. If the +Program specifies that a certain numbered version of the GNU General +Public License "or any later version" applies to it, you have the +option of following the terms and conditions either of that numbered +version or of any later version published by the Free Software +Foundation. If the Program does not specify a version number of the +GNU General Public License, you may choose any version ever published +by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future +versions of the GNU General Public License can be used, that proxy's +public statement of acceptance of a version permanently authorizes you +to choose that version for the Program. + + Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + + 15. Disclaimer of Warranty. + + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM +IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF +ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. Limitation of Liability. + + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE +USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF +SUCH DAMAGES. + + 17. Interpretation of Sections 15 and 16. + + If the disclaimer of warranty and limitation of liability provided +above cannot be given local legal effect according to their terms, +reviewing courts shall apply local law that most closely approximates +an absolute waiver of all civil liability in connection with the +Program, unless a warranty or assumption of liability accompanies a +copy of the Program in return for a fee. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +state the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software: you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation, either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program. If not, see . + +Also add information on how to contact you by electronic and paper mail. + + If the program does terminal interaction, make it output a short +notice like this when it starts in an interactive mode: + + Copyright (C) + This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, your program's commands +might be different; for a GUI interface, you would use an "about box". + + You should also get your employer (if you work as a programmer) or school, +if any, to sign a "copyright disclaimer" for the program, if necessary. +For more information on this, and how to apply and follow the GNU GPL, see +. + + The GNU General Public License does not permit incorporating your program +into proprietary programs. If your program is a subroutine library, you +may consider it more useful to permit linking proprietary applications with +the library. If this is what you want to do, use the GNU Lesser General +Public License instead of this License.

By contrast, +the GNU General Public License is intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains free +software for all its users. We, the Free Software Foundation, use the +GNU General Public License for most of our software; it applies also to +any other work released this way by its authors. You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + + To protect your rights, we need to prevent others from denying you +these rights or asking you to surrender the rights. Therefore, you have +certain responsibilities if you distribute copies of the software, or if +you modify it: responsibilities to respect the freedom of others. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received. You must make sure that they, too, receive +or can get the source code. And you must show them these terms so they +know their rights. + + Developers that use the GNU GPL protect your rights with two steps: +(1) assert copyright on the software, and (2) offer you this License +giving you legal permission to copy, distribute and/or modify it. + + For the developers' and authors' protection, the GPL clearly explains +that there is no warranty for this free software. For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + + Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the manufacturer +can do so. This is fundamentally incompatible with the aim of +protecting users' freedom to change the software. The systematic +pattern of such abuse occurs in the area of products for individuals to +use, which is precisely where it is most unacceptable. Therefore, we +have designed this version of the GPL to prohibit the practice for those +products. If such problems arise substantially in other domains, we +stand ready to extend this provision to those domains in future versions +of the GPL, as needed to protect the freedom of users. + + Finally, every program is threatened constantly by software patents. +States should not allow patents to restrict development and use of +software on general-purpose computers, but in those that do, we wish to +avoid the special danger that patents applied to a free program could +make it effectively proprietary. To prevent this, the GPL assures that +patents cannot be used to render the program non-free. + + The precise terms and conditions for copying, distribution and +modification follow. + + TERMS AND CONDITIONS + + 0. Definitions. + + "This License" refers to version 3 of the GNU General Public License. + + "Copyright" also means copyright-like laws that apply to other kinds of +works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this +License. Each licensee is addressed as "you". "Licensees" and +"recipients" may be individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of an +exact copy. The resulting work is called a "modified version" of the +earlier work or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work based +on the Program. + + To "propagate" a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + + To "convey" a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user through +a computer network, with no transfer of a copy, is not conveying. + + An interactive user interface displays "Appropriate Legal Notices" +to the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work +for making modifications to it. "Object code" means any non-source +form of a work. + + A "Standard Interface" means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + + The "System Libraries" of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +"Major Component", in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + + The Corresponding Source need not include anything that users +can regenerate automatically from other parts of the Corresponding +Source. + + The Corresponding Source for a work in source code form is that +same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + + You may make, run and propagate covered works that you do not +convey, without conditions so long as your license otherwise remains +in force. You may convey covered works to others for the sole purpose +of having them make modifications exclusively for you, or provide you +with facilities for running those works, provided that you comply with +the terms of this License in conveying all material for which you do +not control copyright. Those thus making or running the covered works +for you must do so exclusively on your behalf, under your direction +and control, on terms that prohibit them from making any copies of +your copyrighted material outside their relationship with you. + + Conveying under any other circumstances is permitted solely under +the conditions stated below. Sublicensing is not allowed; section 10 +makes it unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + + When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such circumvention +is effected by exercising rights under this License with respect to +the covered work, and you disclaim any intention to limit operation or +modification of the work as a means of enforcing, against the work's +users, your or third parties' legal rights to forbid circumvention of +technological measures. + + 4. Conveying Verbatim Copies. + + You may convey verbatim copies of the Program's source code as you +receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these conditions: + + a) The work must carry prominent notices stating that you modified + it, and giving a relevant date. + + b) The work must carry prominent notices stating that it is + released under this License and any conditions added under section + 7. This requirement modifies the requirement in section 4 to + "keep intact all notices". + + c) You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable section 7 + additional terms, to the whole of the work, and all its parts, + regardless of how they are packaged. This License gives no + permission to license the work in any other way, but it does not + invalidate such permission if you have separately received it. + + d) If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has interactive + interfaces that do not display Appropriate Legal Notices, your + work need not make them do so. + + A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +"aggregate" if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms +of sections 4 and 5, provided that you also convey the +machine-readable Corresponding Source under the terms of this License, +in one of these ways: + + a) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for as + long as you offer spare parts or customer support for that product + model, to give anyone who possesses the object code either (1) a + copy of the Corresponding Source for all the software in the + product that is covered by this License, on a durable physical + medium customarily used for software interchange, for a price no + more than your reasonable cost of physically performing this + conveying of source, or (2) access to copy the + Corresponding Source from a network server at no charge. + + c) Convey individual copies of the object code with a copy of the + written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, and + only if you received the object code with such an offer, in accord + with subsection 6b. + + d) Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access to the + Corresponding Source in the same way through the same place at no + further charge. You need not require recipients to copy the + Corresponding Source along with the object code. If the place to + copy the object code is a network server, the Corresponding Source + may be on a different server (operated by you or a third party) + that supports equivalent copying facilities, provided you maintain + clear directions next to the object code saying where to find the + Corresponding Source. Regardless of what server hosts the + Corresponding Source, you remain obligated to ensure that it is + available for as long as needed to satisfy these requirements. + + e) Convey the object code using peer-to-peer transmission, provided + you inform other peers where the object code and Corresponding + Source of the work are being offered to the general public at no + charge under subsection 6d. + + A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means any +tangible personal property which is normally used for personal, family, +or household purposes, or (2) anything designed or sold for incorporation +into a dwelling. In determining whether a product is a consumer product, +doubtful cases shall be resolved in favor of coverage. For a particular +product received by a particular user, "normally used" refers to a +typical or common use of that class of product, regardless of the status +of the particular user or of the way in which the particular user +actually uses, or expects or is expected to use, the product. A product +is a consumer product regardless of whether the product has substantial +commercial, industrial or non-consumer uses, unless such uses represent +the only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, +procedures, authorization keys, or other information required to install +and execute modified versions of a covered work in that User Product from +a modified version of its Corresponding Source. The information must +suffice to ensure that the continued functioning of the modified object +code is in no case prevented or interfered with solely because +modification has been made. + + If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + + The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or updates +for a work that has been modified or installed by the recipient, or for +the User Product in which it has been modified or installed. Access to a +network may be denied when the modification itself materially and +adversely affects the operation of the network or violates the rules and +protocols for communication across the network. + + Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + + When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders of +that material) supplement the terms of this License with terms: + + a) Disclaiming warranty or limiting liability differently from the + terms of sections 15 and 16 of this License; or + + b) Requiring preservation of specified reasonable legal notices or + author attributions in that material or in the Appropriate Legal + Notices displayed by works containing it; or + + c) Prohibiting misrepresentation of the origin of that material, or + requiring that modified versions of such material be marked in + reasonable ways as different from the original version; or + + d) Limiting the use for publicity purposes of names of licensors or + authors of the material; or + + e) Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f) Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified versions of + it) with contractual assumptions of liability to the recipient, for + any liability that these contractual assumptions directly impose on + those licensors and authors. + + All other non-permissive additional terms are considered "further +restrictions" within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + + If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; +the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + + However, if you cease all violation of this License, then your +license from a particular copyright holder is reinstated (a) +provisionally, unless and until the copyright holder explicitly and +finally terminates your license, and (b) permanently, if the copyright +holder fails to notify you of the violation by some reasonable means +prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + + Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or +run a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + + An "entity transaction" is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + + You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's "contributor version". + + A contributor's "essential patent claims" are all patent claims +owned or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, "control" includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + + Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + + In the following three paragraphs, a "patent license" is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To "grant" such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + + If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. "Knowingly relying" means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + + A patent license is "discriminatory" if it does not include within +the scope of its coverage, prohibits the exercise of, or is +conditioned on the non-exercise of one or more of the rights that are +specifically granted under this License. You may not convey a covered +work if you are a party to an arrangement with a third party that is +in the business of distributing software, under which you make payment +to the third party based on the extent of your activity of conveying +the work, and under which the third party grants, to any of the +parties who would receive the covered work from you, a discriminatory +patent license (a) in connection with copies of the covered work +conveyed by you (or copies made from those copies), or (b) primarily +for and in connection with specific products or compilations that +contain the covered work, unless you entered into that arrangement, +or that patent license was granted, prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot convey a +covered work so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you may +not convey it at all. For example, if you agree to terms that obligate you +to collect a royalty for further conveying from those to whom you convey +the Program, the only way you could satisfy both those terms and this +License would be to refrain entirely from conveying the Program. + + 13. Use with the GNU Affero General Public License. + + Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU Affero General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the special requirements of the GNU Affero General Public License, +section 13, concerning interaction through a network will apply to the +combination as such. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of +the GNU General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + + Each version is given a distinguishing version number. If the +Program specifies that a certain numbered version of the GNU General +Public License "or any later version" applies to it, you have the +option of following the terms and conditions either of that numbered +version or of any later version published by the Free Software +Foundation. If the Program does not specify a version number of the +GNU General Public License, you may choose any version ever published +by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future +versions of the GNU General Public License can be used, that proxy's +public statement of acceptance of a version permanently authorizes you +to choose that version for the Program. + + Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + + 15. Disclaimer of Warranty. + + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM +IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF +ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. Limitation of Liability. + + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE +USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF +SUCH DAMAGES. + + 17. Interpretation of Sections 15 and 16. + + If the disclaimer of warranty and limitation of liability provided +above cannot be given local legal effect according to their terms, +reviewing courts shall apply local law that most closely approximates +an absolute waiver of all civil liability in connection with the +Program, unless a warranty or assumption of liability accompanies a +copy of the Program in return for a fee. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +state the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software: you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation, either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program. If not, see . + +Also add information on how to contact you by electronic and paper mail. + + If the program does terminal interaction, make it output a short +notice like this when it starts in an interactive mode: + + Copyright (C) + This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, your program's commands +might be different; for a GUI interface, you would use an "about box". + + You should also get your employer (if you work as a programmer) or school, +if any, to sign a "copyright disclaimer" for the program, if necessary. +For more information on this, and how to apply and follow the GNU GPL, see +. + + The GNU General Public License does not permit incorporating your program +into proprietary programs. If your program is a subroutine library, you +may consider it more useful to permit linking proprietary applications with +the library. If this is what you want to do, use the GNU Lesser General +Public License instead of this License.

These Warranty +Disclaimers are considered to be included by reference in this +License, but only as regards disclaiming warranties: any other +implication that these Warranty Disclaimers may have is void and has +no effect on the meaning of this License. + +@item +VERBATIM COPYING + +You may copy and distribute the Document in any medium, either +commercially or noncommercially, provided that this License, the +copyright notices, and the license notice saying this License applies +to the Document are reproduced in all copies, and that you add no other +conditions whatsoever to those of this License. You may not use +technical measures to obstruct or control the reading or further +copying of the copies you make or distribute. However, you may accept +compensation in exchange for copies. If you distribute a large enough +number of copies you must also follow the conditions in section 3. + +You may also lend copies, under the same conditions stated above, and +you may publicly display copies. + +@item +COPYING IN QUANTITY + +If you publish printed copies (or copies in media that commonly have +printed covers) of the Document, numbering more than 100, and the +Document's license notice requires Cover Texts, you must enclose the +copies in covers that carry, clearly and legibly, all these Cover +Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on +the back cover. Both covers must also clearly and legibly identify +you as the publisher of these copies. The front cover must present +the full title with all words of the title equally prominent and +visible. You may add other material on the covers in addition. +Copying with changes limited to the covers, as long as they preserve +the title of the Document and satisfy these conditions, can be treated +as verbatim copying in other respects. + +If the required texts for either cover are too voluminous to fit +legibly, you should put the first ones listed (as many as fit +reasonably) on the actual cover, and continue the rest onto adjacent +pages. + +If you publish or distribute Opaque copies of the Document numbering +more than 100, you must either include a machine-readable Transparent +copy along with each Opaque copy, or state in or with each Opaque copy +a computer-network location from which the general network-using +public has access to download using public-standard network protocols +a complete Transparent copy of the Document, free of added material. +If you use the latter option, you must take reasonably prudent steps, +when you begin distribution of Opaque copies in quantity, to ensure +that this Transparent copy will remain thus accessible at the stated +location until at least one year after the last time you distribute an +Opaque copy (directly or through your agents or retailers) of that +edition to the public. + +It is requested, but not required, that you contact the authors of the +Document well before redistributing any large number of copies, to give +them a chance to provide you with an updated version of the Document. + +@item +MODIFICATIONS + +You may copy and distribute a Modified Version of the Document under +the conditions of sections 2 and 3 above, provided that you release +the Modified Version under precisely this License, with the Modified +Version filling the role of the Document, thus licensing distribution +and modification of the Modified Version to whoever possesses a copy +of it. In addition, you must do these things in the Modified Version: + +@enumerate A +@item +Use in the Title Page (and on the covers, if any) a title distinct +from that of the Document, and from those of previous versions +(which should, if there were any, be listed in the History section +of the Document). You may use the same title as a previous version +if the original publisher of that version gives permission. + +@item +List on the Title Page, as authors, one or more persons or entities +responsible for authorship of the modifications in the Modified +Version, together with at least five of the principal authors of the +Document (all of its principal authors, if it has fewer than five), +unless they release you from this requirement. + +@item +State on the Title page the name of the publisher of the +Modified Version, as the publisher. + +@item +Preserve all the copyright notices of the Document. + +@item +Add an appropriate copyright notice for your modifications +adjacent to the other copyright notices. + +@item +Include, immediately after the copyright notices, a license notice +giving the public permission to use the Modified Version under the +terms of this License, in the form shown in the Addendum below. + +@item +Preserve in that license notice the full lists of Invariant Sections +and required Cover Texts given in the Document's license notice. + +@item +Include an unaltered copy of this License. + +@item +Preserve the section Entitled ``History'', Preserve its Title, and add +to it an item stating at least the title, year, new authors, and +publisher of the Modified Version as given on the Title Page. If +there is no section Entitled ``History'' in the Document, create one +stating the title, year, authors, and publisher of the Document as +given on its Title Page, then add an item describing the Modified +Version as stated in the previous sentence. + +@item +Preserve the network location, if any, given in the Document for +public access to a Transparent copy of the Document, and likewise +the network locations given in the Document for previous versions +it was based on. These may be placed in the ``History'' section. +You may omit a network location for a work that was published at +least four years before the Document itself, or if the original +publisher of the version it refers to gives permission. + +@item +For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve +the Title of the section, and preserve in the section all the +substance and tone of each of the contributor acknowledgements and/or +dedications given therein. + +@item +Preserve all the Invariant Sections of the Document, +unaltered in their text and in their titles. Section numbers +or the equivalent are not considered part of the section titles. + +@item +Delete any section Entitled ``Endorsements''. Such a section +may not be included in the Modified Version. + +@item +Do not retitle any existing section to be Entitled ``Endorsements'' or +to conflict in title with any Invariant Section. + +@item +Preserve any Warranty Disclaimers. +@end enumerate + +If the Modified Version includes new front-matter sections or +appendices that qualify as Secondary Sections and contain no material +copied from the Document, you may at your option designate some or all +of these sections as invariant. To do this, add their titles to the +list of Invariant Sections in the Modified Version's license notice. +These titles must be distinct from any other section titles. + +You may add a section Entitled ``Endorsements'', provided it contains +nothing but endorsements of your Modified Version by various +parties---for example, statements of peer review or that the text has +been approved by an organization as the authoritative definition of a +standard. + +You may add a passage of up to five words as a Front-Cover Text, and a +passage of up to 25 words as a Back-Cover Text, to the end of the list +of Cover Texts in the Modified Version. Only one passage of +Front-Cover Text and one of Back-Cover Text may be added by (or +through arrangements made by) any one entity. If the Document already +includes a cover text for the same cover, previously added by you or +by arrangement made by the same entity you are acting on behalf of, +you may not add another; but you may replace the old one, on explicit +permission from the previous publisher that added the old one. + +The author(s) and publisher(s) of the Document do not by this License +give permission to use their names for publicity for or to assert or +imply endorsement of any Modified Version. + +@item +COMBINING DOCUMENTS + +You may combine the Document with other documents released under this +License, under the terms defined in section 4 above for modified +versions, provided that you include in the combination all of the +Invariant Sections of all of the original documents, unmodified, and +list them all as Invariant Sections of your combined work in its +license notice, and that you preserve all their Warranty Disclaimers. + +The combined work need only contain one copy of this License, and +multiple identical Invariant Sections may be replaced with a single +copy. If there are multiple Invariant Sections with the same name but +different contents, make the title of each such section unique by +adding at the end of it, in parentheses, the name of the original +author or publisher of that section if known, or else a unique number. +Make the same adjustment to the section titles in the list of +Invariant Sections in the license notice of the combined work. + +In the combination, you must combine any sections Entitled ``History'' +in the various original documents, forming one section Entitled +``History''; likewise combine any sections Entitled ``Acknowledgements'', +and any sections Entitled ``Dedications''. You must delete all +sections Entitled ``Endorsements.'' + +@item +COLLECTIONS OF DOCUMENTS + +You may make a collection consisting of the Document and other documents +released under this License, and replace the individual copies of this +License in the various documents with a single copy that is included in +the collection, provided that you follow the rules of this License for +verbatim copying of each of the documents in all other respects. + +You may extract a single document from such a collection, and distribute +it individually under this License, provided you insert a copy of this +License into the extracted document, and follow this License in all +other respects regarding verbatim copying of that document. + +@item +AGGREGATION WITH INDEPENDENT WORKS + +A compilation of the Document or its derivatives with other separate +and independent documents or works, in or on a volume of a storage or +distribution medium, is called an ``aggregate'' if the copyright +resulting from the compilation is not used to limit the legal rights +of the compilation's users beyond what the individual works permit. +When the Document is included in an aggregate, this License does not +apply to the other works in the aggregate which are not themselves +derivative works of the Document. + +If the Cover Text requirement of section 3 is applicable to these +copies of the Document, then if the Document is less than one half of +the entire aggregate, the Document's Cover Texts may be placed on +covers that bracket the Document within the aggregate, or the +electronic equivalent of covers if the Document is in electronic form. +Otherwise they must appear on printed covers that bracket the whole +aggregate. + +@item +TRANSLATION + +Translation is considered a kind of modification, so you may +distribute translations of the Document under the terms of section 4. +Replacing Invariant Sections with translations requires special +permission from their copyright holders, but you may include +translations of some or all Invariant Sections in addition to the +original versions of these Invariant Sections. You may include a +translation of this License, and all the license notices in the +Document, and any Warranty Disclaimers, provided that you also include +the original English version of this License and the original versions +of those notices and disclaimers. In case of a disagreement between +the translation and the original version of this License or a notice +or disclaimer, the original version will prevail. + +If a section in the Document is Entitled ``Acknowledgements'', +``Dedications'', or ``History'', the requirement (section 4) to Preserve +its Title (section 1) will typically require changing the actual +title. + +@item +TERMINATION + +You may not copy, modify, sublicense, or distribute the Document +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense, or distribute it is void, and +will automatically terminate your rights under this License. + +However, if you cease all violation of this License, then your license +from a particular copyright holder is reinstated (a) provisionally, +unless and until the copyright holder explicitly and finally +terminates your license, and (b) permanently, if the copyright holder +fails to notify you of the violation by some reasonable means prior to +60 days after the cessation. + +Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + +Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, receipt of a copy of some or all of the same material does +not give you any rights to use it. + +@item +FUTURE REVISIONS OF THIS LICENSE + +The Free Software Foundation may publish new, revised versions +of the GNU Free Documentation License from time to time. Such new +versions will be similar in spirit to the present version, but may +differ in detail to address new problems or concerns. See +@uref{http://www.gnu.org/copyleft/}. + +Each version of the License is given a distinguishing version number. +If the Document specifies that a particular numbered version of this +License ``or any later version'' applies to it, you have the option of +following the terms and conditions either of that specified version or +of any later version that has been published (not as a draft) by the +Free Software Foundation. If the Document does not specify a version +number of this License, you may choose any version ever published (not +as a draft) by the Free Software Foundation. If the Document +specifies that a proxy can decide which future versions of this +License can be used, that proxy's public statement of acceptance of a +version permanently authorizes you to choose that version for the +Document. + +@item +RELICENSING + +``Massive Multiauthor Collaboration Site'' (or ``MMC Site'') means any +World Wide Web server that publishes copyrightable works and also +provides prominent facilities for anybody to edit those works. A +public wiki that anybody can edit is an example of such a server.

The @sc{gnu} +History library is able to keep track of those lines, associate arbitrary +data with each line, and utilize information from previous lines in +composing new ones. + +A programmer using the History library has available functions +for remembering lines on a history list, associating arbitrary data +with a line, removing lines from the list, searching through the list +for a line containing an arbitrary text string, and referencing any line +in the list directly. In addition, a history @dfn{expansion} function +is available which provides for a consistent user interface across +different programs. + +The user using programs written with the History library has the +benefit of a consistent user interface with a set of well-known +commands for manipulating the text of previous lines and using that text +in new commands. The basic history manipulation commands are similar to +the history substitution provided by @code{csh}. + +The programmer can also use the Readline library, which +includes some history manipulation by default, and has the added +advantage of command line editing. + +Before declaring any functions using any functionality the History +library provides in other code, an application writer should include +the file @code{} in any file that uses the +History library's features. It supplies extern declarations for all +of the library's public functions and variables, and declares all of +the public data structures. + +@node History Storage +@section History Storage + +The history list is an array of history entries.

If @var{first} is not specified, it is set to the previous +command for editing and @minus{}16 for listing. If the @option{-l} flag is +given, the commands are listed on standard output. The @option{-n} flag +suppresses the command numbers when listing. The @option{-r} flag +reverses the order of the listing. Otherwise, the editor given by +@var{ename} is invoked on a file containing those commands. If +@var{ename} is not given, the value of the following variable expansion +is used: @code{$@{FCEDIT:-$@{EDITOR:-vi@}@}}.

This section +describes the syntax used to manipulate the history information. + +History expansions introduce words from the history list into +the input stream, making it easy to repeat commands, insert the +arguments to a previous command into the current input line, or +fix errors in previous commands quickly. + +@ifset BashFeatures +History expansion is performed immediately after a complete line +is read, before the shell breaks it into words, and is performed +on each line individually. Bash attempts to inform the history +expansion functions about quoting still in effect from previous lines. +@end ifset + +History expansion takes place in two parts. The first is to determine +which line from the history list should be used during substitution. +The second is to select portions of that line for inclusion into the +current one. The line selected from the history is called the +@dfn{event}, and the portions of that line that are acted upon are +called @dfn{words}. Various @dfn{modifiers} are available to manipulate +the selected words. The line is broken into words in the same fashion +that Bash does, so that several words +surrounded by quotes are considered one word. +History expansions are introduced by the appearance of the +history expansion character, which is @samp{!} by default. + +History expansion implements shell-like quoting conventions: +a backslash can be used to remove the special handling for the next character; +single quotes enclose verbatim sequences of characters, and can be used to +inhibit history expansion; +and characters enclosed within double quotes may be subject to history +expansion, since backslash can escape the history expansion character, +but single quotes may not, since they are not treated specially within +double quotes. + +@ifset BashFeatures +When using the shell, only @samp{\} and @samp{'} may be used to escape the +history expansion character, but the history expansion character is +also treated as quoted if it immediately precedes the closing double quote +in a double-quoted string. +@end ifset + +@ifset BashFeatures +Several shell options settable with the @code{shopt} +builtin (@pxref{The Shopt Builtin}) may be used to tailor +the behavior of history expansion. If the +@code{histverify} shell option is enabled, and Readline +is being used, history substitutions are not immediately passed to +the shell parser. +Instead, the expanded line is reloaded into the Readline +editing buffer for further modification. +If Readline is being used, and the @code{histreedit} +shell option is enabled, a failed history expansion will be +reloaded into the Readline editing buffer for correction. +The @option{-p} option to the @code{history} builtin command +may be used to see what a history expansion will do before using it. +The @option{-s} option to the @code{history} builtin may be used to +add commands to the end of the history list without actually executing +them, so that they are available for subsequent recall. +This is most useful in conjunction with Readline. + +The shell allows control of the various characters used by the +history expansion mechanism with the @code{histchars} variable, +as explained above (@pxref{Bash Variables}).

For such programs, the default behaviour of +Readline is sufficient. This section describes how to use Readline in +the simplest way possible, perhaps to replace calls in your code to +@code{gets()} or @code{fgets()}. + +@findex readline +@cindex readline, function + +The function @code{readline()} prints a prompt @var{prompt} +and then reads and returns a single line of text from the user. +If @var{prompt} is @code{NULL} or the empty string, no prompt is displayed. +The line @code{readline} returns is allocated with @code{malloc()}; +the caller should @code{free()} the line when it has finished with it. +The declaration for @code{readline} in ANSI C is + +@example +@code{char *readline (const char *@var{prompt});} +@end example + +@noindent +So, one might say +@example +@code{char *line = readline ("Enter a line: ");} +@end example +@noindent +in order to read a line of text from the user. +The line returned has the final newline removed, so only the +text remains. + +If @code{readline} encounters an @code{EOF} while reading the line, and the +line is empty at that point, then @code{(char *)NULL} is returned. +Otherwise, the line is ended just as if a newline had been typed. + +Readline performs some expansion on the @var{prompt} before it is +displayed on the screen. See the description of @code{rl_expand_prompt} +(@pxref{Redisplay}) for additional details, especially if @var{prompt} +will contain characters that do not consume physical screen space when +displayed. + +If you want the user to be able to get at the line later, (with +@key{C-p} for example), you must call @code{add_history()} to save the +line away in a @dfn{history} list of such lines. + +@example +@code{add_history (line)}; +@end example + +@noindent +For full details on the GNU History Library, see the associated manual. + +It is preferable to avoid saving empty lines on the history list, since +users rarely have a burning need to reuse a blank line. Here is +a function which usefully replaces the standard @code{gets()} library +function, and has the advantage of no static buffer to overflow: + +@example +/* A static variable for holding the line. */ +static char *line_read = (char *)NULL; + +/* Read a string, and return a pointer to it. + Returns NULL on EOF. */ +char * +rl_gets () +@{ + /* If the buffer has already been allocated, + return the memory to the free pool. */ + if (line_read) + @{ + free (line_read); + line_read = (char *)NULL; + @} + + /* Get a line from the user. */ + line_read = readline (""); + + /* If the line has any text in it, + save it on the history. */ + if (line_read && *line_read) + add_history (line_read); + + return (line_read); +@} +@end example + +This function gives the user the default behaviour of @key{TAB} +completion: completion on file names. If you do not want Readline to +complete on filenames, you can change the binding of the @key{TAB} key +with @code{rl_bind_key()}. + +@example +@code{int rl_bind_key (int @var{key}, rl_command_func_t *@var{function});} +@end example + +@code{rl_bind_key()} takes two arguments: @var{key} is the character that +you want to bind, and @var{function} is the address of the function to +call when @var{key} is pressed. Binding @key{TAB} to @code{rl_insert()} +makes @key{TAB} insert itself. +@code{rl_bind_key()} returns non-zero if @var{key} is not a valid +ASCII character code (between 0 and 255). + +Thus, to disable the default @key{TAB} behavior, the following suffices: +@example +@code{rl_bind_key ('\t', rl_insert);} +@end example + +This code should be executed once at the start of your program; you +might write a function called @code{initialize_readline()} which +performs this and other desired initializations, such as installing +custom completers (@pxref{Custom Completers}). + +@node Custom Functions +@section Custom Functions + +Readline provides many functions for manipulating the text of +the line, but it isn't possible to anticipate the needs of all +programs. This section describes the various functions and variables +defined within the Readline library which allow a user program to add +customized functionality to Readline. + +Before declaring any functions that customize Readline's behavior, or +using any functionality Readline provides in other code, an +application writer should include the file @code{} +in any file that uses Readline's features. Since some of the definitions +in @code{readline.h} use the @code{stdio} library, the file +@code{} should be included before @code{readline.h}. + +@code{readline.h} defines a C preprocessor variable that should +be treated as an integer, @code{RL_READLINE_VERSION}, which may +be used to conditionally compile application code depending on +the installed Readline version. The value is a hexadecimal +encoding of the major and minor version numbers of the library, +of the form 0x@var{MMmm}. @var{MM} is the two-digit major +version number; @var{mm} is the two-digit minor version number. +For Readline 4.2, for example, the value of +@code{RL_READLINE_VERSION} would be @code{0x0402}. + +@menu +* Readline Typedefs:: C declarations to make code readable. +* Function Writing:: Variables and calling conventions. +@end menu + +@node Readline Typedefs +@subsection Readline Typedefs + +For readability, we declare a number of new object types, all pointers +to functions. + +The reason for declaring these new types is to make it easier to write +code describing pointers to C functions with appropriately prototyped +arguments and return values. + +For instance, say we want to declare a variable @var{func} as a pointer +to a function which takes two @code{int} arguments and returns an +@code{int} (this is the type of all of the Readline bindable functions). +Instead of the classic C declaration + +@code{int (*func)();} + +@noindent +or the ANSI-C style declaration + +@code{int (*func)(int, int);} + +@noindent +we may write + +@code{rl_command_func_t *func;} + +The full list of function pointer types available is + +@table @code +@item typedef int rl_command_func_t (int, int); + +@item typedef char *rl_compentry_func_t (const char *, int); + +@item typedef char **rl_completion_func_t (const char *, int, int); + +@item typedef char *rl_quote_func_t (char *, int, char *); + +@item typedef char *rl_dequote_func_t (char *, int); + +@item typedef int rl_compignore_func_t (char **); + +@item typedef void rl_compdisp_func_t (char **, int, int); + +@item typedef int rl_hook_func_t (void); + +@item typedef int rl_getc_func_t (FILE *); + +@item typedef int rl_linebuf_func_t (char *, int); + +@item typedef int rl_intfunc_t (int); +@item #define rl_ivoidfunc_t rl_hook_func_t +@item typedef int rl_icpfunc_t (char *); +@item typedef int rl_icppfunc_t (char **); + +@item typedef void rl_voidfunc_t (void); +@item typedef void rl_vintfunc_t (int); +@item typedef void rl_vcpfunc_t (char *); +@item typedef void rl_vcppfunc_t (char **); + +@end table + +@node Function Writing +@subsection Writing a New Function + +In order to write new functions for Readline, you need to know the +calling conventions for keyboard-invoked functions, and the names of the +variables that describe the current state of the line read so far. + +The calling sequence for a command @code{foo} looks like + +@example +@code{int foo (int count, int key)} +@end example + +@noindent +where @var{count} is the numeric argument (or 1 if defaulted) and +@var{key} is the key that invoked this function. + +It is completely up to the function as to what should be done with the +numeric argument. Some functions use it as a repeat count, some +as a flag, and others to choose alternate behavior (refreshing the current +line as opposed to refreshing the screen, for example). Some choose to +ignore it. In general, if a +function uses the numeric argument as a repeat count, it should be able +to do something useful with both negative and positive arguments. +At the very least, it should be aware that it can be passed a +negative argument. + +A command function should return 0 if its action completes successfully, +and a value greater than zero if some error occurs. +This is the convention obeyed by all of the builtin Readline bindable +command functions. + +@node Readline Variables +@section Readline Variables + +These variables are available to function writers. + +@deftypevar {char *} rl_line_buffer +This is the line gathered so far.

They are intended to indicate +exceptional events, like a user pressing the interrupt key on his terminal, +or a network connection being broken. There is a class of signals that can +be sent to the process currently reading input from the keyboard. Since +Readline changes the terminal attributes when it is called, it needs to +perform special processing when such a signal is received in order to +restore the terminal to a sane state, or provide application writers with +functions to do so manually. + +Readline contains an internal signal handler that is installed for a +number of signals (@code{SIGINT}, @code{SIGQUIT}, @code{SIGTERM}, +@code{SIGHUP}, +@code{SIGALRM}, @code{SIGTSTP}, @code{SIGTTIN}, and @code{SIGTTOU}). +When one of these signals is received, the signal handler +will reset the terminal attributes to those that were in effect before +@code{readline()} was called, reset the signal handling to what it was +before @code{readline()} was called, and resend the signal to the calling +application. +If and when the calling application's signal handler returns, Readline +will reinitialize the terminal and continue to accept input. +When a @code{SIGINT} is received, the Readline signal handler performs +some additional work, which will cause any partially-entered line to be +aborted (see the description of @code{rl_free_line_state()} below). + +There is an additional Readline signal handler, for @code{SIGWINCH}, which +the kernel sends to a process whenever the terminal's size changes (for +example, if a user resizes an @code{xterm}). The Readline @code{SIGWINCH} +handler updates Readline's internal screen size information, and then calls +any @code{SIGWINCH} signal handler the calling application has installed. +Readline calls the application's @code{SIGWINCH} signal handler without +resetting the terminal to its original state. If the application's signal +handler does more than update its idea of the terminal size and return (for +example, a @code{longjmp} back to a main processing loop), it @emph{must} +call @code{rl_cleanup_after_signal()} (described below), to restore the +terminal state. + +When an application is using the callback interface +(@pxref{Alternate Interface}), Readline installs signal handlers only for +the duration of the call to @code{rl_callback_read_char}. Applications +using the callback interface should be prepared to clean up Readline's +state if they wish to handle the signal before the line handler completes +and restores the terminal state. + +If an application using the callback interface wishes to have Readline +install its signal handlers at the time the application calls +@code{rl_callback_handler_install} and remove them only when a complete +line of input has been read, it should set the +@code{rl_persistent_signal_handlers} variable to a non-zero value. +This allows an application to defer all of the handling of the signals +Readline catches to Readline. +Applications should use this variable with care; it can result in Readline +catching signals and not acting on them (or allowing the application to react +to them) until the application calls @code{rl_callback_read_char}. This +can result in an application becoming less responsive to keyboard signals +like SIGINT. +If an application does not want or need to perform any signal handling, or +does not need to do any processing between calls to @code{rl_callback_read_char}, +setting this variable may be desirable. + +Readline provides two variables that allow application writers to +control whether or not it will catch certain signals and act on them +when they are received.

That is, it is not possible to accurately +expand a partial word without knowing all of the possible words +which make sense in that context. The Readline library provides +the user interface to completion, and two of the most common +completion functions: filename and username. For completing other types +of text, you must write your own completion function. This section +describes exactly what such functions must do, and provides an example. + +There are three major functions used to perform completion: + +@enumerate +@item +The user-interface function @code{rl_complete()}. This function is +called with the same arguments as other bindable Readline functions: +@var{count} and @var{invoking_key}. +It isolates the word to be completed and calls +@code{rl_completion_matches()} to generate a list of possible completions. +It then either lists the possible completions, inserts the possible +completions, or actually performs the +completion, depending on which behavior is desired. + +@item +The internal function @code{rl_completion_matches()} uses an +application-supplied @dfn{generator} function to generate the list of +possible matches, and then returns the array of these matches. +The caller should place the address of its generator function in +@code{rl_completion_entry_function}. + +@item +The generator function is called repeatedly from +@code{rl_completion_matches()}, returning a string each time. The +arguments to the generator function are @var{text} and @var{state}. +@var{text} is the partial word to be completed. @var{state} is zero the +first time the function is called, allowing the generator to perform +any necessary initialization, and a positive non-zero integer for +each subsequent call. The generator function returns +@code{(char *)NULL} to inform @code{rl_completion_matches()} that there are +no more possibilities left. Usually the generator function computes the +list of possible completions when @var{state} is zero, and returns them +one at a time on subsequent calls. Each string the generator function +returns as a match must be allocated with @code{malloc()}; Readline +frees the strings when it has finished with them. +Such a generator function is referred to as an +@dfn{application-specific completion function}. + +@end enumerate + +@deftypefun int rl_complete (int ignore, int invoking_key) +Complete the word at or before point.

This function can +re-arrange the list of matches as required, but each element deleted +from the array must be freed. +@end deftypevar + +@deftypevar {rl_icppfunc_t *} rl_directory_completion_hook +This function, if defined, is allowed to modify the directory portion +of filenames Readline completes. +It could be used to expand symbolic links or shell variables in pathnames. +It is called with the address of a string (the current directory name) as an +argument, and may modify that string. +If the string is replaced with a new string, the old value should be freed. +Any modified directory name should have a trailing slash. +The modified value will be used as part of the completion, replacing +the directory portion of the pathname the user typed. +At the least, even if no other expansion is performed, this function should +remove any quote characters from the directory name, because its result will +be passed directly to @code{opendir()}. + +The directory completion hook returns an integer that should be non-zero if +the function modifies its directory argument. +The function should not modify the directory argument if it returns 0. +@end deftypevar + +@deftypevar {rl_icppfunc_t *} rl_directory_rewrite_hook; +If non-zero, this is the address of a function to call when completing +a directory name. This function takes the address of the directory name +to be modified as an argument. Unlike @code{rl_directory_completion_hook}, +it only modifies the directory name used in @code{opendir}, not what is +displayed when the possible completions are printed or inserted. It is +called before rl_directory_completion_hook. +At the least, even if no other expansion is performed, this function should +remove any quote characters from the directory name, because its result will +be passed directly to @code{opendir()}. + +The directory rewrite hook returns an integer that should be non-zero if +the function modifies its directory argument. +The function should not modify the directory argument if it returns 0. +@end deftypevar + +@deftypevar {rl_icppfunc_t *} rl_filename_stat_hook +If non-zero, this is the address of a function for the completer to +call before deciding which character to append to a completed name. +This function modifies its filename name argument, and the modified value +is passed to @code{stat()} to determine the file's type and characteristics. +This function does not need to remove quote characters from the filename. + +The stat hook returns an integer that should be non-zero if +the function modifies its directory argument. +The function should not modify the directory argument if it returns 0. +@end deftypevar + +@deftypevar {rl_dequote_func_t *} rl_filename_rewrite_hook +If non-zero, this is the address of a function called when reading +directory entries from the filesystem for completion and comparing +them to the partial word to be completed. The function should +perform any necessary application or system-specific conversion on +the filename, such as converting between character sets or converting +from a filesystem format to a character input format. +The function takes two arguments: @var{fname}, the filename to be converted, +and @var{fnlen}, its length in bytes. +It must either return its first argument (if no conversion takes place) +or the converted filename in newly-allocated memory. The converted +form is used to compare against the word to be completed, and, if it +matches, is added to the list of matches. Readline will free the +allocated string. +@end deftypevar + +@deftypevar {rl_compdisp_func_t *} rl_completion_display_matches_hook +If non-zero, then this is the address of a function to call when +completing a word would normally display the list of possible matches. +This function is called in lieu of Readline displaying the list. +It takes three arguments: +(@code{char **}@var{matches}, @code{int} @var{num_matches}, @code{int} @var{max_length}) +where @var{matches} is the array of matching strings, +@var{num_matches} is the number of strings in that array, and +@var{max_length} is the length of the longest string in that array. +Readline provides a convenience function, @code{rl_display_match_list}, +that takes care of doing the display to Readline's output stream. +You may call that function from this hook. +@end deftypevar + +@deftypevar {const char *} rl_basic_word_break_characters +The basic list of characters that signal a break between words for the +completer routine. The default value of this variable is the characters +which break words for completion in Bash: +@code{" \t\n\"\\'`@@$><=;|&@{("}. +@end deftypevar + +@deftypevar {const char *} rl_basic_quote_characters +A list of quote characters which can cause a word break. +@end deftypevar + +@deftypevar {const char *} rl_completer_word_break_characters +The list of characters that signal a break between words for +@code{rl_complete_internal()}. The default list is the value of +@code{rl_basic_word_break_characters}. +@end deftypevar + +@deftypevar {rl_cpvfunc_t *} rl_completion_word_break_hook +If non-zero, this is the address of a function to call when Readline is +deciding where to separate words for word completion. It should return +a character string like @code{rl_completer_word_break_characters} to be +used to perform the current completion. The function may choose to set +@code{rl_completer_word_break_characters} itself. If the function +returns @code{NULL}, @code{rl_completer_word_break_characters} is used. +@end deftypevar + +@deftypevar {const char *} rl_completer_quote_characters +A list of characters which can be used to quote a substring of the line. +Completion occurs on the entire substring, and within the substring +@code{rl_completer_word_break_characters} are treated as any other character, +unless they also appear within this list. +@end deftypevar + +@deftypevar {const char *} rl_filename_quote_characters +A list of characters that cause a filename to be quoted by the completer +when they appear in a completed filename. The default is the null string. +@end deftypevar + +@deftypevar {const char *} rl_special_prefixes +The list of characters that are word break characters, but should be +left in @var{text} when it is passed to the completion function. +Programs can use this to help determine what kind of completing to do. +For instance, Bash sets this variable to "$@@" so that it can complete +shell variables and hostnames. +@end deftypevar + +@deftypevar int rl_completion_query_items +Up to this many items will be displayed in response to a +possible-completions call. After that, readline asks the user if she is sure +she wants to see them all. The default value is 100. A negative value +indicates that Readline should never ask the user. +@end deftypevar + +@deftypevar {int} rl_completion_append_character +When a single completion alternative matches at the end of the command +line, this character is appended to the inserted completion text. The +default is a space character (@samp{ }). Setting this to the null +character (@samp{\0}) prevents anything being appended automatically. +This can be changed in application-specific completion functions to +provide the ``most sensible word separator character'' according to +an application-specific command line syntax specification. +It is set to the default before any application-specific completion function +is called, and may only be changed within such a function. +@end deftypevar + +@deftypevar int rl_completion_suppress_append +If non-zero, @var{rl_completion_append_character} is not appended to +matches at the end of the command line, as described above. +It is set to 0 before any application-specific completion function +is called, and may only be changed within such a function. +@end deftypevar + +@deftypevar int rl_completion_quote_character +When Readline is completing quoted text, as delimited by one of the +characters in @var{rl_completer_quote_characters}, it sets this variable +to the quoting character found. +This is set before any application-specific completion function is called. +@end deftypevar + +@deftypevar int rl_completion_suppress_quote +If non-zero, Readline does not append a matching quote character when +performing completion on a quoted string. +It is set to 0 before any application-specific completion function +is called, and may only be changed within such a function. +@end deftypevar + +@deftypevar int rl_completion_found_quote +When Readline is completing quoted text, it sets this variable +to a non-zero value if the word being completed contains or is delimited +by any quoting characters, including backslashes. +This is set before any application-specific completion function is called. +@end deftypevar + +@deftypevar int rl_completion_mark_symlink_dirs +If non-zero, a slash will be appended to completed filenames that are +symbolic links to directory names, subject to the value of the +user-settable @var{mark-directories} variable. +This variable exists so that application-specific completion functions +can override the user's global preference (set via the +@var{mark-symlinked-directories} Readline variable) if appropriate. +This variable is set to the user's preference before any +application-specific completion function is called, so unless that +function modifies the value, the user's preferences are honored. +@end deftypevar + +@deftypevar int rl_ignore_completion_duplicates +If non-zero, then duplicates in the matches are removed. +The default is 1. +@end deftypevar + +@deftypevar int rl_filename_completion_desired +Non-zero means that the results of the matches are to be treated as +filenames. This is @emph{always} zero when completion is attempted, +and can only be changed +within an application-specific completion function. If it is set to a +non-zero value by such a function, directory names have a slash appended +and Readline attempts to quote completed filenames if they contain any +characters in @code{rl_filename_quote_characters} and +@code{rl_filename_quoting_desired} is set to a non-zero value. +@end deftypevar + +@deftypevar int rl_filename_quoting_desired +Non-zero means that the results of the matches are to be quoted using +double quotes (or an application-specific quoting mechanism) if the +completed filename contains any characters in +@code{rl_filename_quote_chars}. This is @emph{always} non-zero +when completion is attempted, and can only be changed within an +application-specific completion function. +The quoting is effected via a call to the function pointed to +by @code{rl_filename_quoting_function}. +@end deftypevar + +@deftypevar int rl_attempted_completion_over +If an application-specific completion function assigned to +@code{rl_attempted_completion_function} sets this variable to a non-zero +value, Readline will not perform its default filename completion even +if the application's completion function returns no matches. +It should be set only by an application's completion function. +@end deftypevar + +@deftypevar int rl_sort_completion_matches +If an application sets this variable to 0, Readline will not sort the +list of completions (which implies that it cannot remove any duplicate +completions). The default value is 1, which means that Readline will +sort the completions and, depending on the value of +@code{rl_ignore_completion_duplicates}, will attempt to remove duplicate +matches. +@end deftypevar + +@deftypevar int rl_completion_type +Set to a character describing the type of completion Readline is currently +attempting; see the description of @code{rl_complete_internal()} +(@pxref{Completion Functions}) for the list of characters. +This is set to the appropriate value before any application-specific +completion function is called, allowing such functions to present +the same interface as @code{rl_complete()}. +@end deftypevar + +@deftypevar int rl_completion_invoking_key +Set to the final character in the key sequence that invoked one of the +completion functions that call @code{rl_complete_internal()}.

Specifically, +@key{DEL}, @key{ESC}, @key{LFD}, @key{SPC}, @key{RET}, and @key{TAB} all +stand for themselves when seen in this text, or in an init file +(@pxref{Readline Init File}). +If your keyboard lacks a @key{LFD} key, typing @key{C-j} will +produce the desired character. +The @key{RET} key may be labeled @key{Return} or @key{Enter} on +some keyboards. + +@node Readline Interaction +@section Readline Interaction +@cindex interaction, readline + +Often during an interactive session you type in a long line of text, +only to notice that the first word on the line is misspelled. The +Readline library gives you a set of commands for manipulating the text +as you type it in, allowing you to just fix your typo, and not forcing +you to retype the majority of the line. Using these editing commands, +you move the cursor to the place that needs correction, and delete or +insert the text of the corrections. Then, when you are satisfied with +the line, you simply press @key{RET}. You do not have to be at the +end of the line to press @key{RET}; the entire line is accepted +regardless of the location of the cursor within the line. + +@menu +* Readline Bare Essentials:: The least you need to know about Readline. +* Readline Movement Commands:: Moving about the input line. +* Readline Killing Commands:: How to delete text, and how to get it back! +* Readline Arguments:: Giving numeric arguments to commands. +* Searching:: Searching through previous lines. +@end menu + +@node Readline Bare Essentials +@subsection Readline Bare Essentials +@cindex notation, readline +@cindex command editing +@cindex editing command lines + +In order to enter characters into the line, simply type them. The typed +character appears where the cursor was, and then the cursor moves one +space to the right. If you mistype a character, you can use your +erase character to back up and delete the mistyped character. + +Sometimes you may mistype a character, and +not notice the error until you have typed several other characters. In +that case, you can type @kbd{C-b} to move the cursor to the left, and then +correct your mistake. Afterwards, you can move the cursor to the right +with @kbd{C-f}. + +When you add text in the middle of a line, you will notice that characters +to the right of the cursor are `pushed over' to make room for the text +that you have inserted. Likewise, when you delete text behind the cursor, +characters to the right of the cursor are `pulled back' to fill in the +blank space created by the removal of the text. A list of the bare +essentials for editing the text of an input line follows. + +@table @asis +@item @kbd{C-b} +Move back one character. +@item @kbd{C-f} +Move forward one character. +@item @key{DEL} or @key{Backspace} +Delete the character to the left of the cursor. +@item @kbd{C-d} +Delete the character underneath the cursor. +@item @w{Printing characters} +Insert the character into the line at the cursor. +@item @kbd{C-_} or @kbd{C-x C-u} +Undo the last editing command. You can undo all the way back to an +empty line. +@end table + +@noindent +(Depending on your configuration, the @key{Backspace} key be set to +delete the character to the left of the cursor and the @key{DEL} key set +to delete the character underneath the cursor, like @kbd{C-d}, rather +than the character to the left of the cursor.) + +@node Readline Movement Commands +@subsection Readline Movement Commands + + +The above table describes the most basic keystrokes that you need +in order to do editing of the input line. For your convenience, many +other commands have been added in addition to @kbd{C-b}, @kbd{C-f}, +@kbd{C-d}, and @key{DEL}. Here are some commands for moving more rapidly +about the line. + +@table @kbd +@item C-a +Move to the start of the line. +@item C-e +Move to the end of the line. +@item M-f +Move forward a word, where a word is composed of letters and digits. +@item M-b +Move backward a word. +@item C-l +Clear the screen, reprinting the current line at the top. +@end table + +Notice how @kbd{C-f} moves forward a character, while @kbd{M-f} moves +forward a word. It is a loose convention that control keystrokes +operate on characters while meta keystrokes operate on words. + +@node Readline Killing Commands +@subsection Readline Killing Commands + +@cindex killing text +@cindex yanking text + +@dfn{Killing} text means to delete the text from the line, but to save +it away for later use, usually by @dfn{yanking} (re-inserting) +it back into the line. +(`Cut' and `paste' are more recent jargon for `kill' and `yank'.) + +If the description for a command says that it `kills' text, then you can +be sure that you can get the text back in a different (or the same) +place later. + +When you use a kill command, the text is saved in a @dfn{kill-ring}. +Any number of consecutive kills save all of the killed text together, so +that when you yank it back, you get it all. The kill +ring is not line specific; the text that you killed on a previously +typed line is available to be yanked back later, when you are typing +another line. +@cindex kill ring + +Here is the list of commands for killing text. + +@table @kbd +@item C-k +Kill the text from the current cursor position to the end of the line. + +@item M-d +Kill from the cursor to the end of the current word, or, if between +words, to the end of the next word. +Word boundaries are the same as those used by @kbd{M-f}. + +@item M-@key{DEL} +Kill from the cursor the start of the current word, or, if between +words, to the start of the previous word. +Word boundaries are the same as those used by @kbd{M-b}. + +@item C-w +Kill from the cursor to the previous whitespace. This is different than +@kbd{M-@key{DEL}} because the word boundaries differ. + +@end table + +Here is how to @dfn{yank} the text back into the line. Yanking +means to copy the most-recently-killed text from the kill buffer. + +@table @kbd +@item C-y +Yank the most recently killed text back into the buffer at the cursor. + +@item M-y +Rotate the kill-ring, and yank the new top. You can only do this if +the prior command is @kbd{C-y} or @kbd{M-y}. +@end table + +@node Readline Arguments +@subsection Readline Arguments + +You can pass numeric arguments to Readline commands. Sometimes the +argument acts as a repeat count, other times it is the @i{sign} of the +argument that is significant. If you pass a negative argument to a +command which normally acts in a forward direction, that command will +act in a backward direction. For example, to kill text back to the +start of the line, you might type @samp{M-- C-k}. + +The general way to pass numeric arguments to a command is to type meta +digits before the command. If the first `digit' typed is a minus +sign (@samp{-}), then the sign of the argument will be negative. Once +you have typed one meta digit to get the argument started, you can type +the remainder of the digits, and then the command. For example, to give +the @kbd{C-d} command an argument of 10, you could type @samp{M-1 0 C-d}, +which will delete the next ten characters on the input line. + +@node Searching +@subsection Searching for Commands in the History + +Readline provides commands for searching through the command history +@ifset BashFeatures +(@pxref{Bash History Facilities}) +@end ifset +for lines containing a specified string. +There are two search modes: @dfn{incremental} and @dfn{non-incremental}. + +Incremental searches begin before the user has finished typing the +search string. +As each character of the search string is typed, Readline displays +the next entry from the history matching the string typed so far. +An incremental search requires only as many characters as needed to +find the desired history entry. +To search backward in the history for a particular string, type +@kbd{C-r}. Typing @kbd{C-s} searches forward through the history. +The characters present in the value of the @code{isearch-terminators} variable +are used to terminate an incremental search. +If that variable has not been assigned a value, the @key{ESC} and +@kbd{C-J} characters will terminate an incremental search. +@kbd{C-g} will abort an incremental search and restore the original line. +When the search is terminated, the history entry containing the +search string becomes the current line. + +To find other matching entries in the history list, type @kbd{C-r} or +@kbd{C-s} as appropriate. +This will search backward or forward in the history for the next +entry matching the search string typed so far. +Any other key sequence bound to a Readline command will terminate +the search and execute that command. +For instance, a @key{RET} will terminate the search and accept +the line, thereby executing the command from the history list. +A movement command will terminate the search, make the last line found +the current line, and begin editing. + +Readline remembers the last incremental search string. If two +@kbd{C-r}s are typed without any intervening characters defining a new +search string, any remembered search string is used. + +Non-incremental searches read the entire search string before starting +to search for matching history lines. The search string may be +typed by the user or be part of the contents of the current line. + +@node Readline Init File +@section Readline Init File +@cindex initialization file, readline + +Although the Readline library comes with a set of Emacs-like +keybindings installed by default, it is possible to use a different set +of keybindings. +Any user can customize programs that use Readline by putting +commands in an @dfn{inputrc} file, conventionally in his home directory. +The name of this +@ifset BashFeatures +file is taken from the value of the shell variable @env{INPUTRC}.

When set to a +value greater than zero, common prefixes longer than this value are +replaced with an ellipsis when displaying possible completions. + +@item completion-query-items +@vindex completion-query-items +The number of possible completions that determines when the user is +asked whether the list of possibilities should be displayed. +If the number of possible completions is greater than or equal to this value, +Readline will ask whether or not the user wishes to view them; +otherwise, they are simply listed. +This variable must be set to an integer value greater than or equal to 0. +A negative value means Readline should never ask. +The default limit is @code{100}. + +@item convert-meta +@vindex convert-meta +If set to @samp{on}, Readline will convert characters with the +eighth bit set to an @sc{ascii} key sequence by stripping the eighth +bit and prefixing an @key{ESC} character, converting them to a +meta-prefixed key sequence. The default value is @samp{on}, but +will be set to @samp{off} if the locale is one that contains +eight-bit characters. + +@item disable-completion +@vindex disable-completion +If set to @samp{On}, Readline will inhibit word completion. +Completion characters will be inserted into the line as if they had +been mapped to @code{self-insert}. The default is @samp{off}. + +@item echo-control-characters +@vindex echo-control-characters +When set to @samp{on}, on operating systems that indicate they support it, +readline echoes a character corresponding to a signal generated from the +keyboard. The default is @samp{on}. + +@item editing-mode +@vindex editing-mode +The @code{editing-mode} variable controls which default set of +key bindings is used. By default, Readline starts up in Emacs editing +mode, where the keystrokes are most similar to Emacs.

The value is expanded like a +key binding, so the standard set of meta- and control prefixes and +backslash escape sequences is available. +Use the @samp{\1} and @samp{\2} escapes to begin and end sequences of +non-printing characters, which can be used to embed a terminal control +sequence into the mode string. +The default is @samp{@@}. + +@item enable-bracketed-paste +@vindex enable-bracketed-paste +When set to @samp{On}, Readline will configure the terminal in a way +that will enable it to insert each paste into the editing buffer as a +single string of characters, instead of treating each character as if +it had been read from the keyboard. This can prevent pasted characters +from being interpreted as editing commands. The default is @samp{On}. + +@item enable-keypad +@vindex enable-keypad +When set to @samp{on}, Readline will try to enable the application +keypad when it is called. Some systems need this to enable the +arrow keys. The default is @samp{off}. + +@item enable-meta-key +When set to @samp{on}, Readline will try to enable any meta modifier +key the terminal claims to support when it is called. On many terminals, +the meta key is used to send eight-bit characters. +The default is @samp{on}. + +@item expand-tilde +@vindex expand-tilde +If set to @samp{on}, tilde expansion is performed when Readline +attempts word completion. The default is @samp{off}. + +@item history-preserve-point +@vindex history-preserve-point +If set to @samp{on}, the history code attempts to place the point (the +current cursor position) at the +same location on each history line retrieved with @code{previous-history} +or @code{next-history}.

The default is @samp{on}. + +@item mark-modified-lines +@vindex mark-modified-lines +This variable, when set to @samp{on}, causes Readline to display an +asterisk (@samp{*}) at the start of history lines which have been modified. +This variable is @samp{off} by default. + +@item mark-symlinked-directories +@vindex mark-symlinked-directories +If set to @samp{on}, completed names which are symbolic links +to directories have a slash appended (subject to the value of +@code{mark-directories}). +The default is @samp{off}. + +@item match-hidden-files +@vindex match-hidden-files +This variable, when set to @samp{on}, causes Readline to match files whose +names begin with a @samp{.} (hidden files) when performing filename +completion. +If set to @samp{off}, the leading @samp{.} must be +supplied by the user in the filename to be completed. +This variable is @samp{on} by default. + +@item menu-complete-display-prefix +@vindex menu-complete-display-prefix +If set to @samp{on}, menu completion displays the common prefix of the +list of possible completions (which may be empty) before cycling through +the list. The default is @samp{off}. + +@item output-meta +@vindex output-meta +If set to @samp{on}, Readline will display characters with the +eighth bit set directly rather than as a meta-prefixed escape +sequence. +The default is @samp{off}, but Readline will set it to @samp{on} if the +locale contains eight-bit characters. + +@item page-completions +@vindex page-completions +If set to @samp{on}, Readline uses an internal @code{more}-like pager +to display a screenful of possible completions at a time. +This variable is @samp{on} by default. + +@item print-completions-horizontally +If set to @samp{on}, Readline will display completions with matches +sorted horizontally in alphabetical order, rather than down the screen. +The default is @samp{off}. + +@item revert-all-at-newline +@vindex revert-all-at-newline +If set to @samp{on}, Readline will undo all changes to history lines +before returning when @code{accept-line} is executed. By default, +history lines may be modified and retain individual undo lists across +calls to @code{readline}. The default is @samp{off}. + +@item show-all-if-ambiguous +@vindex show-all-if-ambiguous +This alters the default behavior of the completion functions. If +set to @samp{on}, +words which have more than one possible completion cause the +matches to be listed immediately instead of ringing the bell. +The default value is @samp{off}. + +@item show-all-if-unmodified +@vindex show-all-if-unmodified +This alters the default behavior of the completion functions in +a fashion similar to @var{show-all-if-ambiguous}. +If set to @samp{on}, +words which have more than one possible completion without any +possible partial completion (the possible completions don't share +a common prefix) cause the matches to be listed immediately instead +of ringing the bell. +The default value is @samp{off}. + +@item show-mode-in-prompt +@vindex show-mode-in-prompt +If set to @samp{on}, add a string to the beginning of the prompt +indicating the editing mode: emacs, vi command, or vi insertion. +The mode strings are user-settable (e.g., @var{emacs-mode-string}). +The default value is @samp{off}. + +@item skip-completed-text +@vindex skip-completed-text +If set to @samp{on}, this alters the default completion behavior when +inserting a single match into the line. It's only active when +performing completion in the middle of a word. If enabled, readline +does not insert characters from the completion that match characters +after point in the word being completed, so portions of the word +following the cursor are not duplicated. +For instance, if this is enabled, attempting completion when the cursor +is after the @samp{e} in @samp{Makefile} will result in @samp{Makefile} +rather than @samp{Makefilefile}, assuming there is a single possible +completion. +The default value is @samp{off}. + +@item vi-cmd-mode-string +@vindex vi-cmd-mode-string +If the @var{show-mode-in-prompt} variable is enabled, +this string is displayed immediately before the last line of the primary +prompt when vi editing mode is active and in command mode. +The value is expanded like a +key binding, so the standard set of meta- and control prefixes and +backslash escape sequences is available. +Use the @samp{\1} and @samp{\2} escapes to begin and end sequences of +non-printing characters, which can be used to embed a terminal control +sequence into the mode string. +The default is @samp{(cmd)}. + +@item vi-ins-mode-string +@vindex vi-ins-mode-string +If the @var{show-mode-in-prompt} variable is enabled, +this string is displayed immediately before the last line of the primary +prompt when vi editing mode is active and in insertion mode. +The value is expanded like a +key binding, so the standard set of meta- and control prefixes and +backslash escape sequences is available. +Use the @samp{\1} and @samp{\2} escapes to begin and end sequences of +non-printing characters, which can be used to embed a terminal control +sequence into the mode string. +The default is @samp{(ins)}. + +@item visible-stats +@vindex visible-stats +If set to @samp{on}, a character denoting a file's type +is appended to the filename when listing possible +completions.

This +allows @code{sun} to match both @code{sun} and @code{sun-cmd}, +for instance. + +@item version +The @code{version} test may be used to perform comparisons against +specific Readline versions. +The @code{version} expands to the current Readline version. +The set of comparison operators includes +@samp{=} (and @samp{==}), @samp{!=}, @samp{<=}, @samp{>=}, @samp{<}, +and @samp{>}. +The version number supplied on the right side of the operator consists +of a major version number, an optional decimal point, and an optional +minor version (e.g., @samp{7.1}). If the minor version is omitted, it +is assumed to be @samp{0}. +The operator may be separated from the string @code{version} and +from the version number argument by whitespace. +The following example sets a variable if the Readline version being used +is 7.0 or newer: +@example +$if version >= 7.0 +set show-mode-in-prompt on +$endif +@end example + +@item application +The @var{application} construct is used to include +application-specific settings. Each program using the Readline +library sets the @var{application name}, and you can test for +a particular value. +This could be used to bind key sequences to functions useful for +a specific program. For instance, the following command adds a +key sequence that quotes the current or previous word in Bash: +@example +$if Bash +# Quote the current or previous word +"\C-xq": "\eb\"\ef\"" +$endif +@end example + +@item variable +The @var{variable} construct provides simple equality tests for Readline +variables and values. +The permitted comparison operators are @samp{=}, @samp{==}, and @samp{!=}. +The variable name must be separated from the comparison operator by +whitespace; the operator may be separated from the value on the right hand +side by whitespace. +Both string and boolean variables may be tested. Boolean variables must be +tested against the values @var{on} and @var{off}. +The following example is equivalent to the @code{mode=emacs} test described +above: +@example +$if editing-mode == emacs +set show-mode-in-prompt on +$endif +@end example +@end table + +@item $endif +This command, as seen in the previous example, terminates an +@code{$if} command. + +@item $else +Commands in this branch of the @code{$if} directive are executed if +the test fails. + +@item $include +This directive takes a single filename as an argument and reads commands +and bindings from that file. +For example, the following directive reads from @file{/etc/inputrc}: +@example +$include /etc/inputrc +@end example +@end table + +@node Sample Init File +@subsection Sample Init File + +Here is an example of an @var{inputrc} file.

the function or command has complete freedom in generating +the matches. + +Any function specified with @option{-F} is invoked first. +The function may use any of the shell facilities, including the +@code{compgen} and @code{compopt} builtins described below +(@pxref{Programmable Completion Builtins}), to generate the matches. +It must put the possible completions in the @env{COMPREPLY} array +variable, one per array element. + +Next, any command specified with the @option{-C} option is invoked +in an environment equivalent to command substitution. +It should print a list of completions, one per line, to +the standard output. +Backslash may be used to escape a newline, if necessary. + +After all of the possible completions are generated, any filter +specified with the @option{-X} option is applied to the list. +The filter is a pattern as used for pathname expansion; a @samp{&} +in the pattern is replaced with the text of the word being completed. +A literal @samp{&} may be escaped with a backslash; the backslash +is removed before attempting a match. +Any completion that matches the pattern will be removed from the list. +A leading @samp{!} negates the pattern; in this case any completion +not matching the pattern will be removed. +If the @code{nocasematch} shell option +(see the description of @code{shopt} in @ref{The Shopt Builtin}) +is enabled, the match is performed without regard to the case +of alphabetic characters. + +Finally, any prefix and suffix specified with the @option{-P} and @option{-S} +options are added to each member of the completion list, and the result is +returned to the Readline completion code as the list of possible +completions. + +If the previously-applied actions do not generate any matches, and the +@option{-o dirnames} option was supplied to @code{complete} when the +compspec was defined, directory name completion is attempted. + +If the @option{-o plusdirs} option was supplied to @code{complete} when +the compspec was defined, directory name completion is attempted and any +matches are added to the results of the other actions. + +By default, if a compspec is found, whatever it generates is returned to +the completion code as the full set of possible completions. +The default Bash completions are not attempted, and the Readline default +of filename completion is disabled. +If the @option{-o bashdefault} option was supplied to @code{complete} when +the compspec was defined, the default Bash completions are attempted +if the compspec generates no matches. +If the @option{-o default} option was supplied to @code{complete} when the +compspec was defined, Readline's default completion will be performed +if the compspec (and, if attempted, the default Bash completions) +generate no matches. + +When a compspec indicates that directory name completion is desired, +the programmable completion functions force Readline to append a slash +to completed names which are symbolic links to directories, subject to +the value of the @var{mark-directories} Readline variable, regardless +of the setting of the @var{mark-symlinked-directories} Readline variable. + +There is some support for dynamically modifying completions. This is +most useful when used in combination with a default completion specified +with @option{-D}. It's possible for shell functions executed as completion +handlers to indicate that completion should be retried by returning an +exit status of 124. If a shell function returns 124, and changes +the compspec associated with the command on which completion is being +attempted (supplied as the first argument when the function is executed), +programmable completion restarts from the beginning, with an +attempt to find a new compspec for that command. This allows a set of +completions to be built dynamically as completion is attempted, rather than +being loaded all at once. + +For instance, assuming that there is a library of compspecs, each kept in a +file corresponding to the name of the command, the following default +completion function would load completions dynamically: + +@example +_completion_loader() +@{ + .

This function uses the word passed as @code{$2} +to determine the directory name to complete. You can also use the +@code{COMP_WORDS} array variable; the current word is indexed by the +@code{COMP_CWORD} variable. + +The function relies on the @code{complete} and @code{compgen} builtins +to do much of the work, adding only the things that the Bash @code{cd} +does beyond accepting basic directory names: +tilde expansion (@pxref{Tilde Expansion}), +searching directories in @var{$CDPATH}, which is described above +(@pxref{Bourne Shell Builtins}), +and basic support for the @code{cdable_vars} shell option +(@pxref{The Shopt Builtin}). +@code{_comp_cd} modifies the value of @var{IFS} so that it contains only +a newline to accommodate file names containing spaces and tabs -- +@code{compgen} prints the possible completions it generates one per line. + +Possible completions go into the @var{COMPREPLY} array variable, one +completion per array element.

The @option{-o filenames} option tells Readline +that the possible completions should be treated as filenames, and quoted +appropriately. That option will also cause Readline to append a slash to +filenames it can determine are directories (which is why we might want to +extend @code{_comp_cd} to append a slash if we're using directories found +via @var{CDPATH}: Readline can't tell those completions are directories). +The @option{-o nospace} option tells Readline to not append a space +character to the directory name, in case we want to append to it. +The @option{-o bashdefault} option brings in the rest of the "Bash default" +completions -- possible completion that Bash adds to the default Readline +set. These include things like command name completion, variable completion +for words beginning with @samp{$} or @samp{$@{}, completions containing pathname +expansion patterns (@pxref{Filename Expansion}), and so on. + +Once installed using @code{complete}, @code{_comp_cd} will be called every +time we attempt word completion for a @code{cd} command. + +Many more examples -- an extensive collection of completions for most of +the common GNU, Unix, and Linux commands -- are available as part of the +bash_completion project.

Specifically, I've been using the perl +version Term::ReadLine::Gnu. It works great. + +Anyway, I've been playing around the alternate interface and I wanted +to contribute a little C program, callback.c, to you that you could +use as an example of the alternate interface in the /examples +directory of the readline distribution. + +My example shows how, using the alternate interface, you can +interactively change the prompt (which is very nice imo). Also, I +point out that you must roll your own terminal setting when using the +alternate interface because readline depreps (using your parlance) the +terminal while in the user callback. I try to demostrate what I mean +with an example. I've included the program below. + +To compile, I just put the program in the examples directory and made +the appropriate changes to the EXECUTABLES and OBJECTS line and added +an additional target 'callback'. + +I compiled on my Sun Solaris2.6 box using Sun's cc. + +Let me know what you think. + +Jeff +*/ +/* +Copyright (C) 1999 Jeff Solomon +*/ + +#if defined (HAVE_CONFIG_H) +#include +#endif + +#include + +#ifdef HAVE_UNISTD_H +#include +#endif +#include + +#include +#include /* xxx - should make this more general */ + +#ifdef READLINE_LIBRARY +# include "readline.h" +#else +# include +#endif + +#ifndef STDIN_FILENO +# define STDIN_FILENO 0 +#endif + +/* This little examples demonstrates the alternate interface to using readline. + * In the alternate interface, the user maintains control over program flow and + * only calls readline when STDIN is readable. Using the alternate interface, + * you can do anything else while still using readline (like talking to a + * network or another program) without blocking. + * + * Specifically, this program highlights two importants features of the + * alternate interface. The first is the ability to interactively change the + * prompt, which can't be done using the regular interface since rl_prompt is + * read-only. + * + * The second feature really highlights a subtle point when using the alternate + * interface. That is, readline will not alter the terminal when inside your + * callback handler. So let's so, your callback executes a user command that + * takes a non-trivial amount of time to complete (seconds). While your + * executing the command, the user continues to type keystrokes and expects them + * to be re-echoed on the new prompt when it returns. Unfortunately, the default + * terminal configuration doesn't do this. After the prompt returns, the user + * must hit one additional keystroke and then will see all of his previous + * keystrokes. To illustrate this, compile and run this program. Type "sleep" at + * the prompt and then type "bar" before the prompt returns (you have 3 + * seconds). Notice how "bar" is re-echoed on the prompt after the prompt + * returns? This is what you expect to happen. Now comment out the 4 lines below + * the line that says COMMENT LINE BELOW.

Trying to +use dyn with an async trait produces the following error: + +```rust +pub trait Trait { + async fn f(&self); +} + +pub fn make() -> Box { + unimplemented!() +} +``` + +```console +error[E0038]: the trait `Trait` cannot be made into an object + --> src/main.rs:5:22 + | +5 | pub fn make() -> Box { + | ^^^^^^^^^ `Trait` cannot be made into an object + | +note: for a trait to be "object safe" it needs to allow building a vtable to allow the call to be resolvable dynamically; for more information visit + --> src/main.rs:2:14 + | +1 | pub trait Trait { + | ----- this trait cannot be made into an object... +2 | async fn f(&self); + | ^ ...because method `f` is `async` + = help: consider moving `f` to another trait +``` + +This crate provides an attribute macro to make async fn in traits work with dyn +traits. + +Please refer to [*why async fn in traits are hard*][hard] for a deeper analysis +of how this implementation differs from what the compiler and language deliver +natively. + +[hard]: https://smallcultfollowing.com/babysteps/blog/2019/10/26/async-fn-in-traits-are-hard/ + +
+ +## Example + +This example implements the core of a highly effective advertising platform +using async fn in a trait. + +The only thing to notice here is that we write an `#[async_trait]` macro on top +of traits and trait impls that contain async fn, and then they work. We get to +have `Vec>` or `&[&dyn Advertisement]`, for +example. + +```rust +use async_trait::async_trait; + +#[async_trait] +trait Advertisement { + async fn run(&self); +} + +struct Modal; + +#[async_trait] +impl Advertisement for Modal { + async fn run(&self) { + self.render_fullscreen().await; + for _ in 0..4u16 { + remind_user_to_join_mailing_list().await; + } + self.hide_for_now().await; + } +} + +struct AutoplayingVideo { + media_url: String, +} + +#[async_trait] +impl Advertisement for AutoplayingVideo { + async fn run(&self) { + let stream = connect(&self.media_url).await; + stream.play().await; + + // Video probably persuaded user to join our mailing list! + Modal.run().await; + } +} +``` + +
+ +## Supported features + +It is the intention that all features of Rust traits should work nicely with +\#\[async_trait\], but the edge cases are numerous. *Please file an issue if you +see unexpected borrow checker errors, type errors, or warnings.* There is no use +of `unsafe` in the expanded code, so rest assured that if your code compiles it +can't be that badly broken. + +- 👍 Self by value, by reference, by mut reference, or no self; +- 👍 Any number of arguments, any return value; +- 👍 Generic type parameters and lifetime parameters; +- 👍 Associated types; +- 👍 Having async and non-async functions in the same trait; +- 👍 Default implementations provided by the trait; +- 👍 Elided lifetimes. + +
+ +## Explanation + +Async fns get transformed into methods that return `Pin>` and delegate to an async block. + +For example the `impl Advertisement for AutoplayingVideo` above would be +expanded as: + +```rust +impl Advertisement for AutoplayingVideo { + fn run<'async_trait>( + &'async_trait self, + ) -> Pin + Send + 'async_trait>> + where + Self: Sync + 'async_trait, + { + Box::pin(async move { + /* the original method body */ + }) + } +} +``` + +
+ +## Non-threadsafe futures + +Not all async traits need futures that are `dyn Future + Send`. To avoid having +Send and Sync bounds placed on the async trait methods, invoke the async trait +macro as `#[async_trait(?Send)]` on both the trait and the impl blocks. + +
+ +## Elided lifetimes + +Be aware that async fn syntax does not allow lifetime elision outside of `&` and +`&mut` references. (This is true even when not using #\[async_trait\].) +Lifetimes must be named or marked by the placeholder `'_`. + +Fortunately the compiler is able to diagnose missing lifetimes with a good error +message. + +```rust +type Elided<'a> = &'a usize; + +#[async_trait] +trait Test { + async fn test(not_okay: Elided, okay: &usize) {} +} +``` + +```console +error[E0726]: implicit elided lifetime not allowed here + --> src/main.rs:9:29 + | +9 | async fn test(not_okay: Elided, okay: &usize) {} + | ^^^^^^- help: indicate the anonymous lifetime: `<'_>` +``` + +The fix is to name the lifetime or use `'_`. + +```rust +#[async_trait] +trait Test { + // either + async fn test<'e>(elided: Elided<'e>) {} + // or + async fn test(elided: Elided<'_>) {} +} +``` + +
+ +## Dyn traits + +Traits with async methods can be used as trait objects as long as they meet the +usual requirements for dyn -- no methods with type parameters, no self by value, +no associated types, etc. + +```rust +#[async_trait] +pub trait ObjectSafe { + async fn f(&self); + async fn g(&mut self); +} + +impl ObjectSafe for MyType {...} + +let value: MyType = ...; +let object = &value as &dyn ObjectSafe; // make trait object +``` + +The one wrinkle is in traits that provide default implementations of async +methods. In order for the default implementation to produce a future that is +Send, the async\_trait macro must emit a bound of `Self: Sync` on trait methods +that take `&self` and a bound `Self: Send` on trait methods that take `&mut +self`. An example of the former is visible in the expanded code in the +explanation section above. + +If you make a trait with async methods that have default implementations, +everything will work except that the trait cannot be used as a trait object. +Creating a value of type `&dyn Trait` will produce an error that looks like +this: + +```console +error: the trait `Test` cannot be made into an object + --> src/main.rs:8:5 + | +8 | async fn cannot_dyn(&self) {} + | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +``` + +For traits that need to be object safe and need to have default implementations +for some async methods, there are two resolutions. Either you can add Send +and/or Sync as supertraits (Send if there are `&mut self` methods with default +implementations, Sync if there are `&self` methods with default implementations) +to constrain all implementors of the trait such that the default implementations +are applicable to them: + +```rust +#[async_trait] +pub trait ObjectSafe: Sync { // added supertrait + async fn can_dyn(&self) {} +} + +let object = &value as &dyn ObjectSafe; +``` + +or you can strike the problematic methods from your trait object by bounding +them with `Self: Sized`: + +```rust +#[async_trait] +pub trait ObjectSafe { + async fn cannot_dyn(&self) where Self: Sized {} + + // presumably other methods +} + +let object = &value as &dyn ObjectSafe; +``` + +

Type erasure for async trait methods

+//! +//! The stabilization of async functions in traits in Rust 1.75 did not include +//! support for using traits containing async functions as `dyn Trait`. Trying +//! to use dyn with an async trait produces the following error: +//! +//! ```compile_fail +//! pub trait Trait { +//! async fn f(&self); +//! } +//! +//! pub fn make() -> Box { +//! unimplemented!() +//! } +//! ``` +//! +//! ```text +//! error[E0038]: the trait `Trait` cannot be made into an object +//! --> src/main.rs:5:22 +//! | +//! 5 | pub fn make() -> Box { +//! | ^^^^^^^^^ `Trait` cannot be made into an object +//! | +//! note: for a trait to be "object safe" it needs to allow building a vtable to allow the call to be resolvable dynamically; for more information visit +//! --> src/main.rs:2:14 +//! | +//! 1 | pub trait Trait { +//! | ----- this trait cannot be made into an object... +//! 2 | async fn f(&self); +//! | ^ ...because method `f` is `async` +//! = help: consider moving `f` to another trait +//! ``` +//! +//! This crate provides an attribute macro to make async fn in traits work with +//! dyn traits. +//! +//! Please refer to [*why async fn in traits are hard*][hard] for a deeper +//! analysis of how this implementation differs from what the compiler and +//! language deliver natively. +//! +//! [hard]: https://smallcultfollowing.com/babysteps/blog/2019/10/26/async-fn-in-traits-are-hard/ +//! +//!
+//! +//! # Example +//! +//! This example implements the core of a highly effective advertising platform +//! using async fn in a trait. +//! +//! The only thing to notice here is that we write an `#[async_trait]` macro on +//! top of traits and trait impls that contain async fn, and then they work. We +//! get to have `Vec>` or `&[&dyn Advertisement]`, +//! for example. +//! +//! ``` +//! use async_trait::async_trait; +//! +//! #[async_trait] +//! trait Advertisement { +//! async fn run(&self); +//! } +//! +//! struct Modal; +//! +//! #[async_trait] +//! impl Advertisement for Modal { +//! async fn run(&self) { +//! self.render_fullscreen().await; +//! for _ in 0..4u16 { +//! remind_user_to_join_mailing_list().await; +//! } +//! self.hide_for_now().await; +//! } +//! } +//! +//! struct AutoplayingVideo { +//! media_url: String, +//! } +//! +//! #[async_trait] +//! impl Advertisement for AutoplayingVideo { +//! async fn run(&self) { +//! let stream = connect(&self.media_url).await; +//! stream.play().await; +//! +//! // Video probably persuaded user to join our mailing list! +//! Modal.run().await; +//! } +//! } +//! # +//! # impl Modal { +//! # async fn render_fullscreen(&self) {} +//! # async fn hide_for_now(&self) {} +//! # } +//! # +//! # async fn remind_user_to_join_mailing_list() {} +//! # +//! # struct Stream; +//! # async fn connect(_media_url: &str) -> Stream { Stream } +//! # impl Stream { +//! # async fn play(&self) {} +//! # } +//! ``` +//! +//!

+//! +//! # Supported features +//! +//! It is the intention that all features of Rust traits should work nicely with +//! #\[async_trait\], but the edge cases are numerous. Please file an issue if +//! you see unexpected borrow checker errors, type errors, or warnings. There is +//! no use of `unsafe` in the expanded code, so rest assured that if your code +//! compiles it can't be that badly broken. +//! +//! > ☑ Self by value, by reference, by mut reference, or no self;
+//! > ☑ Any number of arguments, any return value;
+//! > ☑ Generic type parameters and lifetime parameters;
+//! > ☑ Associated types;
+//! > ☑ Having async and non-async functions in the same trait;
+//! > ☑ Default implementations provided by the trait;
+//! > ☑ Elided lifetimes.
+//! +//!
+//! +//! # Explanation +//! +//! Async fns get transformed into methods that return `Pin>` and delegate to an async block. +//! +//! For example the `impl Advertisement for AutoplayingVideo` above would be +//! expanded as: +//! +//! ``` +//! # const IGNORE: &str = stringify! { +//! impl Advertisement for AutoplayingVideo { +//! fn run<'async_trait>( +//! &'async_trait self, +//! ) -> Pin + Send + 'async_trait>> +//! where +//! Self: Sync + 'async_trait, +//! { +//! Box::pin(async move { +//! /* the original method body */ +//! }) +//! } +//! } +//! # }; +//! ``` +//! +//!

+//! +//! # Non-threadsafe futures +//! +//! Not all async traits need futures that are `dyn Future + Send`. To avoid +//! having Send and Sync bounds placed on the async trait methods, invoke the +//! async trait macro as `#[async_trait(?Send)]` on both the trait and the impl +//! blocks. +//! +//!
+//! +//! # Elided lifetimes +//! +//! Be aware that async fn syntax does not allow lifetime elision outside of `&` +//! and `&mut` references. (This is true even when not using #\[async_trait\].) +//! Lifetimes must be named or marked by the placeholder `'_`. +//! +//! Fortunately the compiler is able to diagnose missing lifetimes with a good +//! error message. +//! +//! ```compile_fail +//! # use async_trait::async_trait; +//! # +//! type Elided<'a> = &'a usize; +//! +//! #[async_trait] +//! trait Test { +//! async fn test(not_okay: Elided, okay: &usize) {} +//! } +//! ``` +//! +//! ```text +//! error[E0726]: implicit elided lifetime not allowed here +//! --> src/main.rs:9:29 +//! | +//! 9 | async fn test(not_okay: Elided, okay: &usize) {} +//! | ^^^^^^- help: indicate the anonymous lifetime: `<'_>` +//! ``` +//! +//! The fix is to name the lifetime or use `'_`. +//! +//! ``` +//! # use async_trait::async_trait; +//! # +//! # type Elided<'a> = &'a usize; +//! # +//! #[async_trait] +//! trait Test { +//! // either +//! async fn test<'e>(elided: Elided<'e>) {} +//! # } +//! # #[async_trait] +//! # trait Test2 { +//! // or +//! async fn test(elided: Elided<'_>) {} +//! } +//! ``` +//! +//!

+//! +//! # Dyn traits +//! +//! Traits with async methods can be used as trait objects as long as they meet +//! the usual requirements for dyn -- no methods with type parameters, no self +//! by value, no associated types, etc. +//! +//! ``` +//! # use async_trait::async_trait; +//! # +//! #[async_trait] +//! pub trait ObjectSafe { +//! async fn f(&self); +//! async fn g(&mut self); +//! } +//! +//! # const IGNORE: &str = stringify! { +//! impl ObjectSafe for MyType {...} +//! +//! let value: MyType = ...; +//! # }; +//! # +//! # struct MyType; +//! # +//! # #[async_trait] +//! # impl ObjectSafe for MyType { +//! # async fn f(&self) {} +//! # async fn g(&mut self) {} +//! # } +//! # +//! # let value: MyType = MyType; +//! let object = &value as &dyn ObjectSafe; // make trait object +//! ``` +//! +//! The one wrinkle is in traits that provide default implementations of async +//! methods. In order for the default implementation to produce a future that is +//! Send, the async_trait macro must emit a bound of `Self: Sync` on trait +//! methods that take `&self` and a bound `Self: Send` on trait methods that +//! take `&mut self`. An example of the former is visible in the expanded code +//! in the explanation section above. +//! +//! If you make a trait with async methods that have default implementations, +//! everything will work except that the trait cannot be used as a trait object. +//! Creating a value of type `&dyn Trait` will produce an error that looks like +//! this: +//! +//! ```text +//! error: the trait `Test` cannot be made into an object +//! --> src/main.rs:8:5 +//! | +//! 8 | async fn cannot_dyn(&self) {} +//! | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +//! ``` +//! +//! For traits that need to be object safe and need to have default +//! implementations for some async methods, there are two resolutions. Either +//! you can add Send and/or Sync as supertraits (Send if there are `&mut self` +//! methods with default implementations, Sync if there are `&self` methods with +//! default implementations) to constrain all implementors of the trait such that +//! the default implementations are applicable to them: +//! +//! ``` +//! # use async_trait::async_trait; +//! # +//! #[async_trait] +//! pub trait ObjectSafe: Sync { // added supertrait +//! async fn can_dyn(&self) {} +//! } +//! # +//! # struct MyType; +//! # +//! # #[async_trait] +//! # impl ObjectSafe for MyType {} +//! # +//! # let value = MyType; +//! +//! let object = &value as &dyn ObjectSafe; +//! ``` +//! +//! or you can strike the problematic methods from your trait object by +//! bounding them with `Self: Sized`: +//! +//! ``` +//! # use async_trait::async_trait; +//! # +//! #[async_trait] +//! pub trait ObjectSafe { +//! async fn cannot_dyn(&self) where Self: Sized {} +//! +//! // presumably other methods +//! } +//! # +//! # struct MyType; +//! # +//! # #[async_trait] +//! # impl ObjectSafe for MyType {} +//! # +//! # let value = MyType;

See [`example_generated::Flags`](./example_generated/struct.Flags.html) for documentation of code +//! generated by the above `bitflags!` expansion. +//! +//! The generated `struct`s can also be extended with type and trait +//! implementations: +//! +//! ``` +//! use std::fmt; +//! +//! use bitflags::bitflags; +//! +//! bitflags! { +//! struct Flags: u32 { +//! const A = 0b00000001; +//! const B = 0b00000010; +//! } +//! } +//! +//! impl Flags { +//! pub fn clear(&mut self) { +//! self.bits = 0; // The `bits` field can be accessed from within the +//! // same module where the `bitflags!` macro was invoked. +//! } +//! } +//! +//! impl fmt::Display for Flags { +//! fn fmt(&self, f: &mut fmt::Formatter) -> fmt::Result { +//! write!(f, "hi!") +//! } +//! } +//! +//! fn main() { +//! let mut flags = Flags::A | Flags::B; +//! flags.clear(); +//! assert!(flags.is_empty()); +//! assert_eq!(format!("{}", flags), "hi!"); +//! assert_eq!(format!("{:?}", Flags::A | Flags::B), "A | B"); +//! assert_eq!(format!("{:?}", Flags::B), "B"); +//! } +//! ``` +//! +//! # Visibility +//! +//! The generated structs and their associated flag constants are not exported +//! out of the current module by default. A definition can be exported out of +//! the current module by adding `pub` before `struct`: +//! +//! ``` +//! mod example { +//! use bitflags::bitflags; +//! +//! bitflags! { +//! pub struct Flags1: u32 { +//! const A = 0b00000001; +//! } +//! +//! # pub +//! struct Flags2: u32 { +//! const B = 0b00000010; +//! } +//! } +//! } +//! +//! fn main() { +//! let flag1 = example::Flags1::A; +//! let flag2 = example::Flags2::B; // error: const `B` is private +//! } +//! ``` +//! +//! # Attributes +//! +//! Attributes can be attached to the generated `struct`s by placing them +//! before the `struct` keyword. +//! +//! ## Representations +//! +//! It's valid to add a `#[repr(C)]` or `#[repr(transparent)]` attribute to a type +//! generated by `bitflags!`. In these cases, the type is guaranteed to be a newtype. +//! +//! ``` +//! use bitflags::bitflags; +//! +//! bitflags! { +//! #[repr(transparent)] +//! struct Flags: u32 { +//! const A = 0b00000001; +//! const B = 0b00000010; +//! const C = 0b00000100; +//! } +//! } +//! ``` +//! +//! # Trait implementations +//! +//! The `Copy`, `Clone`, `PartialEq`, `Eq`, `PartialOrd`, `Ord` and `Hash` +//! traits are automatically derived for the `struct`s using the `derive` attribute. +//! Additional traits can be derived by providing an explicit `derive` +//! attribute on `struct`. +//! +//! The `Extend` and `FromIterator` traits are implemented for the `struct`s, +//! too: `Extend` adds the union of the instances of the `struct` iterated over, +//! while `FromIterator` calculates the union. +//! +//! The `Binary`, `Debug`, `LowerHex`, `Octal` and `UpperHex` traits are also +//! implemented by displaying the bits value of the internal struct. +//! +//! ## Operators +//! +//! The following operator traits are implemented for the generated `struct`s: +//! +//! - `BitOr` and `BitOrAssign`: union +//! - `BitAnd` and `BitAndAssign`: intersection +//! - `BitXor` and `BitXorAssign`: toggle +//! - `Sub` and `SubAssign`: set difference +//! - `Not`: set complement +//! +//! # Methods +//! +//! The following methods are defined for the generated `struct`s: +//! +//! - `empty`: an empty set of flags +//! - `all`: the set of all defined flags +//! - `bits`: the raw value of the flags currently stored +//! - `from_bits`: convert from underlying bit representation, unless that +//! representation contains bits that do not correspond to a +//! defined flag +//! - `from_bits_truncate`: convert from underlying bit representation, dropping +//! any bits that do not correspond to defined flags +//! - `from_bits_unchecked`: convert from underlying bit representation, keeping +//! all bits (even those not corresponding to defined +//! flags) +//! - `is_empty`: `true` if no flags are currently stored +//! - `is_all`: `true` if currently set flags exactly equal all defined flags +//! - `intersects`: `true` if there are flags common to both `self` and `other` +//! - `contains`: `true` if all of the flags in `other` are contained within `self` +//! - `insert`: inserts the specified flags in-place +//! - `remove`: removes the specified flags in-place +//! - `toggle`: the specified flags will be inserted if not present, and removed +//! if they are. +//! - `set`: inserts or removes the specified flags depending on the passed value +//! - `intersection`: returns a new set of flags, containing only the flags present +//! in both `self` and `other` (the argument to the function). +//! - `union`: returns a new set of flags, containing any flags present in +//! either `self` or `other` (the argument to the function). +//! - `difference`: returns a new set of flags, containing all flags present in +//! `self` without any of the flags present in `other` (the +//! argument to the function). +//! - `symmetric_difference`: returns a new set of flags, containing all flags +//! present in either `self` or `other` (the argument +//! to the function), but not both. +//! - `complement`: returns a new set of flags, containing all flags which are +//! not set in `self`, but which are allowed for this type. +//! +//! ## Default +//! +//! The `Default` trait is not automatically implemented for the generated structs. +//! +//! If your default value is equal to `0` (which is the same value as calling `empty()` +//! on the generated struct), you can simply derive `Default`: +//! +//! ``` +//! use bitflags::bitflags; +//! +//! bitflags! { +//! // Results in default value with bits: 0 +//! #[derive(Default)] +//! struct Flags: u32 { +//! const A = 0b00000001; +//! const B = 0b00000010; +//! const C = 0b00000100; +//! } +//! } +//! +//! fn main() { +//! let derived_default: Flags = Default::default(); +//! assert_eq!(derived_default.bits(), 0); +//! } +//! ``` +//! +//! If your default value is not equal to `0` you need to implement `Default` yourself: +//! +//! ``` +//! use bitflags::bitflags; +//! +//! bitflags! { +//! struct Flags: u32 { +//! const A = 0b00000001; +//! const B = 0b00000010; +//! const C = 0b00000100; +//! } +//! } +//! +//! // explicit `Default` implementation +//! impl Default for Flags { +//! fn default() -> Flags { +//! Flags::A | Flags::C +//! } +//! } +//! +//! fn main() { +//! let implemented_default: Flags = Default::default(); +//! assert_eq!(implemented_default, (Flags::A | Flags::C)); +//! } +//! ``` +//! +//! # Zero Flags +//! +//!

+ +### Details + +- A `fmt::Display` impl is generated for your enum if you provide + a docstring comment on each variant as shown above in the example. The + `Display` derive macro supports a shorthand for interpolating fields from + the error: + - `/// {var}` ⟶ `write!("{}", self.var)` + - `/// {0}` ⟶ `write!("{}", self.0)` + - `/// {var:?}` ⟶ `write!("{:?}", self.var)` + - `/// {0:?}` ⟶ `write!("{:?}", self.0)` +- This also works with structs and [generic types][crate::Display#generic-type-parameters]: +```rust +/// oh no, an error: {0} +#[derive(Display)] +pub struct Error(pub E); + +let error: Error<&str> = Error("muahaha i am an error"); +assert!("oh no, an error: muahaha i am an error" == &format!("{}", error)); +``` + +- Two optional attributes can be added to your types next to the derive: + + - `#[ignore_extra_doc_attributes]` makes the macro ignore any doc + comment attributes (or `///` lines) after the first. Multi-line + comments using `///` are otherwise treated as an error, so use this + attribute or consider switching to block doc comments (`/** */`). + + - `#[prefix_enum_doc_attributes]` combines the doc comment message on + your enum itself with the messages for each variant, in the format + “enum: variantâ€. When added to an enum, the doc comment on the enum + becomes mandatory. When added to any other type, it has no effect. + +- In case you want to have an independent doc comment, the + `#[displaydoc("...")` atrribute may be used on the variant or struct to + override it. + +
+ +### FAQ + +1. **Is this crate `no_std` compatible?** + * Yes! This crate implements the [`core::fmt::Display`] trait, not the [`std::fmt::Display`] trait, so it should work in `std` and `no_std` environments. Just add `default-features = false`. + +2. **Does this crate work with `Path` and `PathBuf` via the `Display` trait?** + * Yuuup. This crate uses @dtolnay's [autoref specialization technique](https://github.com/dtolnay/case-studies/blob/master/autoref-specialization/README.md) to add a special trait for types to get the display impl. It then specializes for `Path` and `PathBuf`, and when either of these types are found, it calls `self.display()` to get a `std::path::Display<'_>` type which can be used with the `Display` format specifier! + + +#### License + + +Licensed under either of Apache License, Version +2.0 or MIT license at your option. + + +

+//! +//! ## Details +//! +//! - A `fmt::Display` impl is generated for your enum if you provide +//! a docstring comment on each variant as shown above in the example. The +//! `Display` derive macro supports a shorthand for interpolating fields from +//! the error: +//! - `/// {var}` ⟶ `write!("{}", self.var)` +//! - `/// {0}` ⟶ `write!("{}", self.0)` +//! - `/// {var:?}` ⟶ `write!("{:?}", self.var)` +//! - `/// {0:?}` ⟶ `write!("{:?}", self.0)` +//! - This also works with structs and [generic types][crate::Display#generic-type-parameters]: +//! ```rust +//! # use displaydoc::Display; +//! /// oh no, an error: {0} +//! #[derive(Display)] +//! pub struct Error(pub E); +//! +//! let error: Error<&str> = Error("muahaha i am an error"); +//! assert!("oh no, an error: muahaha i am an error" == &format!("{}", error)); +//! ``` +//! +//! - Two optional attributes can be added to your types next to the derive: +//! +//! - `#[ignore_extra_doc_attributes]` makes the macro ignore any doc +//! comment attributes (or `///` lines) after the first. Multi-line +//! comments using `///` are otherwise treated as an error, so use this +//! attribute or consider switching to block doc comments (`/** */`). +//! +//! - `#[prefix_enum_doc_attributes]` combines the doc comment message on +//! your enum itself with the messages for each variant, in the format +//! “enum: variantâ€. When added to an enum, the doc comment on the enum +//! becomes mandatory. When added to any other type, it has no effect. +//! +//! - In case you want to have an independent doc comment, the +//! `#[displaydoc("...")` atrribute may be used on the variant or struct to +//! override it. +//! +//!
+//! +//! ## FAQ +//! +//! 1. **Is this crate `no_std` compatible?** +//! * Yes! This crate implements the [`core::fmt::Display`] trait, not the [`std::fmt::Display`] trait, so it should work in `std` and `no_std` environments. Just add `default-features = false`. +//! +//! 2. **Does this crate work with `Path` and `PathBuf` via the `Display` trait?** +//! * Yuuup. This crate uses @dtolnay's [autoref specialization technique](https://github.com/dtolnay/case-studies/blob/master/autoref-specialization/README.md) to add a special trait for types to get the display impl. It then specializes for `Path` and `PathBuf`, and when either of these types are found, it calls `self.display()` to get a `std::path::Display<'_>` type which can be used with the `Display` format specifier! +#![doc(html_root_url = "https://docs.rs/displaydoc/0.2.3")] +#![cfg_attr(docsrs, feature(doc_cfg))] +#![warn( + rust_2018_idioms, + unreachable_pub, + bad_style, + dead_code, + improper_ctypes, + non_shorthand_field_patterns, + no_mangle_generic_items, + overflowing_literals, + path_statements, + patterns_in_fns_without_body, + private_in_public, + unconditional_recursion, + unused, + unused_allocation, + unused_comparisons, + unused_parens, + while_true +)] +#![allow(clippy::try_err)] + +#[allow(unused_extern_crates)] +extern crate proc_macro; + +mod attr; +mod expand; +mod fmt; + +use proc_macro::TokenStream; +use syn::{parse_macro_input, DeriveInput}; + +/// [Custom `#[derive(...)]` macro](https://doc.rust-lang.org/edition-guide/rust-2018/macros/custom-derive.html) +/// for implementing [`fmt::Display`][core::fmt::Display] via doc comment attributes. +/// +/// ### Generic Type Parameters +/// +/// Type parameters to an enum or struct using this macro should *not* need to +/// have an explicit `Display` constraint at the struct or enum definition +/// site.

The simplest case is a one-locale list. +/// +/// Fluent uses [`LanguageIdentifier`] which can be created using `langid!` macro. +/// +/// ## Add Resources +/// +/// Next, call [`add_resource`](FluentBundle::add_resource) one or more times, supplying translations in the FTL syntax. +/// +/// Since [`FluentBundle`] is generic over anything that can borrow a [`FluentResource`], +/// one can use [`FluentBundle`] to own its resources, store references to them, +/// or even [`Rc`](std::rc::Rc) or [`Arc`](std::sync::Arc). +/// +/// The [`FluentBundle`] instance is now ready to be used for localization. +/// +/// ## Format +/// +/// To format a translation, call [`get_message`](FluentBundle::get_message) to retrieve a [`FluentMessage`], +/// and then call [`format_pattern`](FluentBundle::format_pattern) on the message value or attribute in order to +/// retrieve the translated string. +/// +/// The result of [`format_pattern`](FluentBundle::format_pattern) is an +/// [`Cow`](std::borrow::Cow). It is +/// recommended to treat the result as opaque from the perspective of the program and use it only +/// to display localized messages. Do not examine it or alter in any way before displaying. This +/// is a general good practice as far as all internationalization operations are concerned. +/// +/// If errors were encountered during formatting, they will be +/// accumulated in the [`Vec`](FluentError) passed as the third argument. +/// +/// While they are not fatal, they usually indicate problems with the translation, +/// and should be logged or reported in a way that allows the developer to notice +/// and fix them. +/// +/// +/// # Locale Fallback Chain +/// +/// [`FluentBundle`] stores messages in a single locale, but keeps a locale fallback chain for the +/// purpose of language negotiation with i18n formatters. For instance, if date and time formatting +/// are not available in the first locale, [`FluentBundle`] will use its `locales` fallback chain +/// to negotiate a sensible fallback for date and time formatting. +/// +/// # Concurrency +/// +/// As you may have noticed, [`fluent_bundle::FluentBundle`](crate::FluentBundle) is a specialization of [`fluent_bundle::bundle::FluentBundle`](crate::bundle::FluentBundle) +/// which works with an [`IntlLangMemoizer`] over [`RefCell`](std::cell::RefCell). +/// In scenarios where the memoizer must work concurrently, there's an implementation of +/// [`IntlLangMemoizer`](intl_memoizer::concurrent::IntlLangMemoizer) that uses [`Mutex`](std::sync::Mutex) and there's [`FluentBundle::new_concurrent`] which works with that. +pub struct FluentBundle { + pub locales: Vec, + pub(crate) resources: Vec, + pub(crate) entries: FxHashMap, + pub(crate) intls: M, + pub(crate) use_isolating: bool, + pub(crate) transform: Option Cow>, + pub(crate) formatter: Option Option>, +} + +impl FluentBundle { + /// Adds a resource to the bundle, returning an empty [`Result`] on success. + /// + /// If any entry in the resource uses the same identifier as an already + /// existing key in the bundle, the new entry will be ignored and a + /// `FluentError::Overriding` will be added to the result. + /// + /// The method can take any type that can be borrowed to `FluentResource`: + /// - FluentResource + /// - &FluentResource + /// - Rc + /// - Arc + /// + /// This allows the user to introduce custom resource management and share + /// resources between instances of `FluentBundle`. + /// + /// # Examples + /// + /// ``` + /// use fluent_bundle::{FluentBundle, FluentResource}; + /// use unic_langid::langid; + /// + /// let ftl_string = String::from(" + /// hello = Hi! + /// goodbye = Bye! + /// "); + /// let resource = FluentResource::try_new(ftl_string) + /// .expect("Could not parse an FTL string."); + /// let langid_en = langid!("en-US"); + /// let mut bundle = FluentBundle::new(vec![langid_en]); + /// bundle.add_resource(resource) + /// .expect("Failed to add FTL resources to the bundle."); + /// assert_eq!(true, bundle.has_message("hello")); + /// ``` + /// + /// # Whitespace + /// + /// Message ids must have no leading whitespace.

Fluent is a modern localization system designed to improve how software is translated. +//! +//! `fluent-fallback` is a high-level component of the [Fluent Localization +//! System](https://www.projectfluent.org). +//! +//! The crate builds on top of the mid-level [`fluent-bundle`](../fluent-bundle) package, and provides an ergonomic API for highly flexible localization. +//! +//! The functionality of this level is complete, but the API itself is in the +//! early stages and the goal of being ergonomic is yet to be achieved. +//! +//! If the user is willing to work through the challenge of setting up the +//! boiler-plate that will eventually go away, `fluent-fallback` provides +//! a powerful abstraction around [`FluentBundle`](fluent_bundle::FluentBundle) coupled +//! with a localization resource management system. +//! +//! The main struct, [`Localization`], is a long-lived, reactive, multi-lingual +//! struct which allows for strong error recovery and locale +//! fallbacking, exposing synchronous and asynchronous ergonomic methods +//! for [`L10nMessage`](types::L10nMessage) retrieval. +//! +//! [`Localization`] is also an API that is to be used when designing bindings +//! to user interface systems, such as DOM, React, and others. +//! +//! # Example +//! +//! ``` +//! use fluent_fallback::{Localization, types::{ResourceType, ToResourceId}}; +//! use fluent_resmgr::ResourceManager; +//! use unic_langid::langid; +//! +//! let res_mgr = ResourceManager::new("./tests/resources/{locale}/".to_string()); +//! +//! let loc = Localization::with_env( +//! vec![ +//!

The above example is far from the ergonomical API style the Fluent project +//! is aiming for, but it represents the full scope of functionality intended +//! for the model. +//! +//! # Resource Management +//! +//! Resource management is one of the most complicated parts of a localization system. +//! In particular, modern software may have needs for both synchronous +//! and asynchronous I/O. That, in turn has a large impact on what can happen +//! in case of missing resources, or errors. +//! +//! Resource identifiers can refer to resources that are either required or optional. +//! In the above example, `"test.ftl"` is a required resource (the default using `.into()`), +//! and `"test2.ftl" is an optional resource, which you can create via the +//! [`ToResourceId`](fluent_fallback::types::ToResourceId) trait. +//! +//! A required resource must be present in order for the a bundle to be considered valid. +//! If a required resource is missing for a given locale, a bundle will not be generated for that locale. +//! +//! A bundle is still considered valid if an optional resource is missing. A bundle will still be generated +//! and the entries for the missing optional resource will simply be missing from the bundle. This should be +//! used sparingly in exceptional cases where you do not want `Localization` to fall back to the next +//! locale if there is a missing resource. Marking all resources as optional will increase the state space +//! that the solver has to search through, and will have a negative impact on performance. +//! +//! Currently, [`Localization`] can be specialized over an implementation of +//! [`generator::BundleGenerator`] trait which provides a method to generate an +//! [`Iterator`] and [`Stream`](futures::stream::Stream). +//! +//! This is not very elegant and will likely be improved in the future, but for the time being, if +//! the customer doesn't need one of the modes, the unnecessary method should use the +//! `unimplemented!()` macro as its body. +//! +//! `fluent-resmgr` provides a simple resource manager which handles synchronous I/O +//! and uses local file system to store resources in a directory structure. +//! +//! That model is often sufficient and the user can either use `fluent-resmgr` or write +//! a similar API to provide the generator for [`Localization`]. +//! +//! Alternatively, a much more sophisticated resource manager can be used. Mozilla +//! for its needs in Firefox uses [`L10nRegistry`](https://github.com/zbraniecki/l10nregistry-rs) +//! library which implements [`BundleGenerator`](generator::BundleGenerator). +//! +//! # Locale Management +//! +//!

Abstractions for asynchronous programming. +//! +//! This crate provides a number of core abstractions for writing asynchronous +//! code: +//! +//! - [Futures](crate::future) are single eventual values produced by +//! asynchronous computations. Some programming languages (e.g. JavaScript) +//! call this concept "promise". +//! - [Streams](crate::stream) represent a series of values +//! produced asynchronously. +//! - [Sinks](crate::sink) provide support for asynchronous writing of +//! data. +//! - [Executors](crate::executor) are responsible for running asynchronous +//! tasks. +//! +//! The crate also contains abstractions for [asynchronous I/O](crate::io) and +//! [cross-task communication](crate::channel). +//! +//! Underlying all of this is the *task system*, which is a form of lightweight +//! threading. Large asynchronous computations are built up using futures, +//! streams and sinks, and then spawned as independent tasks that are run to +//! completion, but *do not block* the thread running them. +//! +//! The following example describes how the task system context is built and used +//! within macros and keywords such as async and await!. +//! +//! ```rust +//! # use futures::channel::mpsc; +//! # use futures::executor; ///standard executors to provide a context for futures and streams +//! # use futures::executor::ThreadPool; +//! # use futures::StreamExt; +//! # +//! fn main() { +//! # { +//! let pool = ThreadPool::new().expect("Failed to build pool"); +//! let (tx, rx) = mpsc::unbounded::(); +//! +//! // Create a future by an async block, where async is responsible for an +//! // implementation of Future. At this point no executor has been provided +//! // to this future, so it will not be running. +//! let fut_values = async { +//! // Create another async block, again where the Future implementation +//! // is generated by async. Since this is inside of a parent async block, +//! // it will be provided with the executor of the parent block when the parent +//! // block is executed. +//! // +//! // This executor chaining is done by Future::poll whose second argument +//! // is a std::task::Context. This represents our executor, and the Future +//! // implemented by this async block can be polled using the parent async +//! // block's executor. +//! let fut_tx_result = async move { +//! (0..100).for_each(|v| { +//! tx.unbounded_send(v).expect("Failed to send"); +//! }) +//! }; +//! +//! // Use the provided thread pool to spawn the generated future +//! // responsible for transmission +//! pool.spawn_ok(fut_tx_result); +//! +//! let fut_values = rx +//! .map(|v| v * 2) +//! .collect(); +//! +//! // Use the executor provided to this async block to wait for the +//! // future to complete. +//! fut_values.await +//! }; +//! +//! // Actually execute the above future, which will invoke Future::poll and +//! // subsequently chain appropriate Future::poll and methods needing executors +//! // to drive all futures. Eventually fut_values will be driven to completion. +//! let values: Vec = executor::block_on(fut_values); +//! +//! println!("Values={:?}", values); +//! # } +//! # std::thread::sleep(std::time::Duration::from_millis(500)); // wait for background threads closed: https://github.com/rust-lang/miri/issues/1371 +//! } +//! ``` +//! +//!

If you are reading this document, it means you are interested in contributing +to the `libc` crate. + +## v0.2 changes + +If you want to add your changes to v0.2, please submit them to the `libc-0.2` branch. +If you want to add any breaking changes, it should be submitted to the main branch, +which has changes for v0.3. +We will support and make a new release for v0.2 until we make the first release of v0.3. + +## Adding an API + +Want to use an API which currently isn't bound in `libc`? It's quite easy to add +one! + +The internal structure of this crate is designed to minimize the number of +`#[cfg]` attributes in order to easily be able to add new items which apply +to all platforms in the future. As a result, the crate is organized +hierarchically based on platform. Each module has a number of `#[cfg]`'d +children, but only one is ever actually compiled. Each module then reexports all +the contents of its children. + +This means that for each platform that libc supports, the path from a +leaf module to the root will contain all bindings for the platform in question. +Consequently, this indicates where an API should be added! Adding an API at a +particular level in the hierarchy means that it is supported on all the child +platforms of that level. For example, when adding a Unix API it should be added +to `src/unix/mod.rs`, but when adding a Linux-only API it should be added to +`src/unix/linux_like/linux/mod.rs`. + +If you're not 100% sure at what level of the hierarchy an API should be added +at, fear not! This crate has CI support which tests any binding against all +platforms supported, so you'll see failures if an API is added at the wrong +level or has different signatures across platforms. + +New symbol(s) (i.e. functions, constants etc.) should also be added to the +symbols list(s) found in the `libc-test/semver` directory. These lists keep +track of what symbols are public in the libc crate and ensures they remain +available between changes to the crate. If the new symbol(s) are available on +all supported Unixes it should be added to `unix.txt` list1, +otherwise they should be added to the OS specific list(s). + +With that in mind, the steps for adding a new API are: + +1. Determine where in the module hierarchy your API should be added. +2. Add the API, including adding new symbol(s) to the semver lists. +3. Send a PR to this repo. +4. Wait for CI to pass, fixing errors. +5. Wait for a merge! + +1: Note that this list has nothing to do with any Unix or Posix +standard, it's just a list shared between all OSs that declare `#[cfg(unix)]`. + +## Test before you commit + +We have two automated tests running on [GitHub Actions](https://github.com/rust-lang/libc/actions): + +1. [`libc-test`](https://github.com/gnzlbg/ctest) + - `cd libc-test && cargo test` + - Use the `skip_*()` functions in `build.rs` if you really need a workaround. +2. Style checker + - [`sh ci/style.sh`](https://github.com/rust-lang/libc/blob/main/ci/style.sh) + +## Breaking change policy + +Sometimes an upstream adds a breaking change to their API e.g. removing outdated items, +changing the type signature, etc. And we probably should follow that change to build the +`libc` crate successfully. It's annoying to do the equivalent of semver-major versioning +for each such change. Instead, we mark the item as deprecated and do the actual change +after a certain period. The steps are: + +1. Add `#[deprecated(since = "", note="")]` attribute to the item. + - The `since` field should have a next version of `libc` + (e.g., if the current version is `0.2.1`, it should be `0.2.2`). + - The `note` field should have a reason to deprecate and a tracking issue to call for comments + (e.g., "We consider removing this as the upstream removed it. + If you're using it, please comment on #XXX"). +2. If we don't see any concerns for a while, do the change actually. + +## Supported target policy + +When Rust removes a support for a target, the libc crate also may remove the support anytime. + +## Releasing your change to crates.io + +Now that you've done the amazing job of landing your new API or your new +platform in this crate, the next step is to get that sweet, sweet usage from +crates.io! The only next step is to bump the version of libc and then publish +it. If you'd like to get a release out ASAP you can follow these steps: + +1. Increment the patch version number in `Cargo.toml` and `libc-test/Cargo.toml`. +1. Send a PR to this repository. It should [look like this][example-pr], but it'd + also be nice to fill out the description with a small rationale for the + release (any rationale is ok though!). +1. Once merged, the release will be tagged and published by one of the libc crate + maintainers. + +[example-pr]: https://github.com/rust-lang/libc/pull/2120 diff --git

When searching for more than one byte, + positions are considered a match if the byte at that position matches any + of the bytes. +* The `memmem` sub-module provides forward and reverse substring search + routines. + +In all such cases, routines operate on `&[u8]` without regard to encoding. This +is exactly what you want when searching either UTF-8 or arbitrary bytes. + +### Compiling without the standard library + +memchr links to the standard library by default, but you can disable the +`std` feature if you want to use it in a `#![no_std]` crate: + +```toml +[dependencies] +memchr = { version = "2", default-features = false } +``` + +On x86 platforms, when the `std` feature is disabled, the SSE2 accelerated +implementations will be used. When `std` is enabled, AVX accelerated +implementations will be used if the CPU is determined to support it at runtime. + +### Using libc + +`memchr` is a routine that is part of libc, although this crate does not use +libc by default. Instead, it uses its own routines, which are either vectorized +or generic fallback routines. In general, these should be competitive with +what's in libc, although this has not been tested for all architectures. If +using `memchr` from libc is desirable and a vectorized routine is not otherwise +available in this crate, then enabling the `libc` feature will use libc's +version of `memchr`. + +The rest of the functions in this crate, e.g., `memchr2` or `memrchr3` and the +substring search routines, will always use the implementations in this crate. +One exception to this is `memrchr`, which is an extension in `libc` found on +Linux. On Linux, `memrchr` is used in precisely the same scenario as `memchr`, +as described above. + + +### Minimum Rust version policy + +This crate's minimum supported `rustc` version is `1.41.1`. + +The current policy is that the minimum Rust version required to use this crate +can be increased in minor version updates. For example, if `crate 1.0` requires +Rust 1.20.0, then `crate 1.0.z` for all values of `z` will also require Rust +1.20.0 or newer. However, `crate 1.y` for `y > 0` may require a newer minimum +version of Rust. + +In general, this crate will be conservative with respect to the minimum +supported version of Rust. + + +### Testing strategy + +Given the complexity of the code in this crate, along with the pervasive use +of `unsafe`, this crate has an extensive testing strategy. It combines multiple +approaches: + +* Hand-written tests. +* Exhaustive-style testing meant to exercise all possible branching and offset + calculations. +* Property based testing through [`quickcheck`](https://github.com/BurntSushi/quickcheck). +* Fuzz testing through [`cargo fuzz`](https://github.com/rust-fuzz/cargo-fuzz). +* A huge suite of benchmarks that are also run as tests. Benchmarks always + confirm that the expected result occurs. + +Improvements to the testing infrastructure are very welcome. + + +### Algorithms used + +At time of writing, this crate's implementation of substring search actually +has a few different algorithms to choose from depending on the situation. + +* For very small haystacks, + [Rabin-Karp](https://en.wikipedia.org/wiki/Rabin%E2%80%93Karp_algorithm) + is used to reduce latency. Rabin-Karp has very small overhead and can often + complete before other searchers have even been constructed. +* For small needles, a variant of the + ["Generic SIMD"](http://0x80.pl/articles/simd-strfind.html#algorithm-1-generic-simd) + algorithm is used. Instead of using the first and last bytes, a heuristic is + used to select bytes based on a background distribution of byte frequencies. +* In all other cases, + [Two-Way](https://en.wikipedia.org/wiki/Two-way_string-matching_algorithm) + is used. If possible, a prefilter based on the "Generic SIMD" algorithm + linked above is used to find candidates quickly. A dynamic heuristic is used + to detect if the prefilter is ineffective, and if so, disables it. diff --git a/utshell-0.5.0/vendor/memchr/UNLICENSE b/utshell-0.5.0/vendor/memchr/UNLICENSE new file mode 100644 index 00000000..68a49daa --- /dev/null +++ b/utshell-0.5.0/vendor/memchr/UNLICENSE @@ -0,0 +1,24 @@ +This is free and unencumbered software released into the public domain. + +Anyone is free to copy, modify, publish, use, compile, sell, or +distribute this software, either in source code form or as a compiled +binary, for any purpose, commercial or non-commercial, and by any +means. + +In jurisdictions that recognize copyright laws, the author or authors +of this software dedicate any and all copyright interest in the +software to the public domain.

When it comes to +performance, at a high level at least, there are two primary ways to look at +it: + +* **Throughput**: For this, think about it as, "given some very large haystack + and a byte that never occurs in that haystack, how long does it take to + search through it and determine that it, in fact, does not occur?" +* **Latency**: For this, think about it as, "given a tiny haystack---just a + few bytes---how long does it take to determine if a byte is in it?" + +The `memchr` routine in this crate has _slightly_ worse latency than the +solution presented above, however, its throughput can easily be over an +order of magnitude faster. This is a good general purpose trade off to make. +You rarely lose, but often gain big. + +**NOTE:** The name `memchr` comes from the corresponding routine in libc. A key +advantage of using this library is that its performance is not tied to its +quality of implementation in the libc you happen to be using, which can vary +greatly from platform to platform. + +But what about substring search? This one is a bit more complicated. The +primary reason for its existence is still indeed performance, but it's also +useful because Rust's core library doesn't actually expose any substring +search routine on arbitrary bytes. The only substring search routine that +exists works exclusively on valid UTF-8. + +So if you have valid UTF-8, is there a reason to use this over the standard +library substring search routine? Yes. This routine is faster on almost every +metric, including latency. The natural question then, is why isn't this +implementation in the standard library, even if only for searching on UTF-8? +The reason is that the implementation details for using SIMD in the standard +library haven't quite been worked out yet. + +**NOTE:** Currently, only `x86_64` targets have highly accelerated +implementations of substring search. For `memchr`, all targets have +somewhat-accelerated implementations, while only `x86_64` targets have highly +accelerated implementations. This limitation is expected to be lifted once the +standard library exposes a platform independent SIMD API. + +# Crate features + +* **std** - When enabled (the default), this will permit this crate to use + features specific to the standard library. Currently, the only thing used + from the standard library is runtime SIMD CPU feature detection. This means + that this feature must be enabled to get AVX accelerated routines. When + `std` is not enabled, this crate will still attempt to use SSE2 accelerated + routines on `x86_64`. +* **libc** - When enabled (**not** the default), this library will use your + platform's libc implementation of `memchr` (and `memrchr` on Linux). This + can be useful on non-`x86_64` targets where the fallback implementation in + this crate is not as good as the one found in your libc.

(For the AVX2 algorithm, 32 is the magic number.) + // Therefore, to get aligned loads, our pointer's address must be evenly + // divisible by 16. + // 2. Our primary loop proceeds 64 bytes at a time instead of 16. It's + // kind of like loop unrolling, but we combine the equality comparisons + // using a vector OR such that we only need to extract a single mask to + // determine whether a match exists or not. If so, then we do some + // book-keeping to determine the precise location but otherwise mush on. + // 3. We use our "chunk" comparison routine in as many places as possible, + // even if it means using unaligned loads. In particular, if haystack + // starts with an unaligned address, then we do an unaligned load to + // search the first 16 bytes. We then start our primary loop at the + // smallest subsequent aligned address, which will actually overlap with + // previously searched bytes. But we're OK with that. We do a similar + // dance at the end of our primary loop. Finally, to avoid a + // byte-at-a-time loop at the end, we do a final 16 byte unaligned load + // that may overlap with a previous load. This is OK because it converts + // a loop into a small number of very fast vector instructions. + // + // The primary downside of this algorithm is that it's effectively + // completely unsafe. Therefore, we have to be super careful to avoid + // undefined behavior: + // + // 1. We use raw pointers everywhere. Not only does dereferencing a pointer + // require the pointer to be valid, but we actually can't even store the + // address of an invalid pointer (unless it's 1 past the end of + // haystack) without sacrificing performance. + // 2. _mm_loadu_si128 is used when you don't care about alignment, and + // _mm_load_si128 is used when you do care.

Provide helpers for making ioctl system calls. +//! +//! This library is pretty low-level and messy. `ioctl` is not fun. +//! +//! What is an `ioctl`? +//! =================== +//! +//! The `ioctl` syscall is the grab-bag syscall on POSIX systems. Don't want to add a new +//! syscall? Make it an `ioctl`! `ioctl` refers to both the syscall, and the commands that can be +//! sent with it. `ioctl` stands for "IO control", and the commands are always sent to a file +//! descriptor. +//! +//! It is common to see `ioctl`s used for the following purposes: +//! +//! * Provide read/write access to out-of-band data related to a device such as configuration +//! (for instance, setting serial port options) +//! * Provide a mechanism for performing full-duplex data transfers (for instance, xfer on SPI +//! devices). +//! * Provide access to control functions on a device (for example, on Linux you can send +//! commands like pause, resume, and eject to the CDROM device. +//! * Do whatever else the device driver creator thought made most sense. +//! +//! `ioctl`s are synchronous system calls and are similar to read and write calls in that regard. +//! They operate on file descriptors and have an identifier that specifies what the ioctl is. +//! Additionally they may read or write data and therefore need to pass along a data pointer. +//! Besides the semantics of the ioctls being confusing, the generation of this identifer can also +//! be difficult. +//! +//! Historically `ioctl` numbers were arbitrary hard-coded values. In Linux (before 2.6) and some +//! unices this has changed to a more-ordered system where the ioctl numbers are partitioned into +//! subcomponents (For linux this is documented in +//! [`Documentation/ioctl/ioctl-number.rst`](https://elixir.bootlin.com/linux/latest/source/Documentation/userspace-api/ioctl/ioctl-number.rst)): +//! +//! * Number: The actual ioctl ID +//! * Type: A grouping of ioctls for a common purpose or driver +//! * Size: The size in bytes of the data that will be transferred +//! * Direction: Whether there is any data and if it's read, write, or both +//! +//! Newer drivers should not generate complete integer identifiers for their `ioctl`s instead +//! preferring to use the 4 components above to generate the final ioctl identifier. Because of +//! how old `ioctl`s are, however, there are many hard-coded `ioctl` identifiers. These are +//! commonly referred to as "bad" in `ioctl` documentation. +//! +//! Defining `ioctl`s +//! ================= +//! +//! This library provides several `ioctl_*!` macros for binding `ioctl`s. These generate public +//! unsafe functions that can then be used for calling the ioctl. This macro has a few different +//! ways it can be used depending on the specific ioctl you're working with. +//! +//! A simple `ioctl` is `SPI_IOC_RD_MODE`. This ioctl works with the SPI interface on Linux. This +//! specific `ioctl` reads the mode of the SPI device as a `u8`. It's declared in +//! `/include/uapi/linux/spi/spidev.h` as `_IOR(SPI_IOC_MAGIC, 1, __u8)`. Since it uses the `_IOR` +//! macro, we know it's a `read` ioctl and can use the `ioctl_read!` macro as follows: +//! +//! ``` +//! # #[macro_use] extern crate nix; +//! const SPI_IOC_MAGIC: u8 = b'k'; // Defined in linux/spi/spidev.h +//! const SPI_IOC_TYPE_MODE: u8 = 1; +//! ioctl_read!(spi_read_mode, SPI_IOC_MAGIC, SPI_IOC_TYPE_MODE, u8); +//! # fn main() {} +//! ``` +//! +//! This generates the function: +//! +//! ``` +//! # #[macro_use] extern crate nix; +//! # use std::mem; +//! # use nix::{libc, Result}; +//! # use nix::errno::Errno; +//! # use nix::libc::c_int as c_int; +//! # const SPI_IOC_MAGIC: u8 = b'k'; // Defined in linux/spi/spidev.h +//! # const SPI_IOC_TYPE_MODE: u8 = 1; +//! pub unsafe fn spi_read_mode(fd: c_int, data: *mut u8) -> Result { +//! let res = libc::ioctl(fd, request_code_read!(SPI_IOC_MAGIC, SPI_IOC_TYPE_MODE, mem::size_of::()), data); +//! Errno::result(res) +//! } +//! # fn main() {} +//! ``` +//! +//! The return value for the wrapper functions generated by the `ioctl_*!` macros are `nix::Error`s. +//! These are generated by assuming the return value of the ioctl is `-1` on error and everything +//! else is a valid return value. If this is not the case, `Result::map` can be used to map some +//! of the range of "good" values (-Inf..-2, 0..Inf) into a smaller range in a helper function. +//! +//! Writing `ioctl`s generally use pointers as their data source and these should use the +//! `ioctl_write_ptr!`. But in some cases an `int` is passed directly. For these `ioctl`s use the +//! `ioctl_write_int!` macro. This variant does not take a type as the last argument: +//! +//! ``` +//! # #[macro_use] extern crate nix; +//! const HCI_IOC_MAGIC: u8 = b'k'; +//! const HCI_IOC_HCIDEVUP: u8 = 1; +//! ioctl_write_int!(hci_dev_up, HCI_IOC_MAGIC, HCI_IOC_HCIDEVUP); +//! # fn main() {} +//! ``` +//! +//! Some `ioctl`s don't transfer any data, and those should use `ioctl_none!`. This macro +//! doesn't take a type and so it is declared similar to the `write_int` variant shown above. +//! +//! The mode for a given `ioctl` should be clear from the documentation if it has good +//! documentation. Otherwise it will be clear based on the macro used to generate the `ioctl` +//! number where `_IO`, `_IOR`, `_IOW`, and `_IOWR` map to "none", "read", "write_*", and "readwrite" +//! respectively. To determine the specific `write_` variant to use you'll need to find +//! what the argument type is supposed to be. If it's an `int`, then `write_int` should be used, +//! otherwise it should be a pointer and `write_ptr` should be used. On Linux the +//! [`ioctl_list` man page](https://man7.org/linux/man-pages/man2/ioctl_list.2.html) describes a +//! large number of `ioctl`s and describes their argument data type. +//! +//! Using "bad" `ioctl`s +//! -------------------- +//! +//! As mentioned earlier, there are many old `ioctl`s that do not use the newer method of +//! generating `ioctl` numbers and instead use hardcoded values. These can be used with the +//! `ioctl_*_bad!` macros. This naming comes from the Linux kernel which refers to these +//! `ioctl`s as "bad". These are a different variant as they bypass calling the macro that generates +//! the ioctl number and instead use the defined value directly. +//! +//! For example the `TCGETS` `ioctl` reads a `termios` data structure for a given file descriptor. +//! It's defined as `0x5401` in `ioctls.h` on Linux and can be implemented as: +//! +//! ``` +//! # #[macro_use] extern crate nix; +//! # #[cfg(any(target_os = "android", target_os = "linux"))] +//! # use nix::libc::TCGETS as TCGETS; +//! # #[cfg(any(target_os = "android", target_os = "linux"))] +//! # use nix::libc::termios as termios; +//! # #[cfg(any(target_os = "android", target_os = "linux"))] +//! ioctl_read_bad!(tcgets, TCGETS, termios); +//! # fn main() {} +//! ``` +//! +//! The generated function has the same form as that generated by `ioctl_read!`: +//! +//! ```text +//! pub unsafe fn tcgets(fd: c_int, data: *mut termios) -> Result; +//! ``` +//! +//! Working with Arrays +//! ------------------- +//! +//! Some `ioctl`s work with entire arrays of elements. These are supported by the `ioctl_*_buf` +//! family of macros: `ioctl_read_buf`, `ioctl_write_buf`, and `ioctl_readwrite_buf`. Note that +//! there are no "bad" versions for working with buffers. The generated functions include a `len` +//! argument to specify the number of elements (where the type of each element is specified in the +//! macro). +//! +//! Again looking to the SPI `ioctl`s on Linux for an example, there is a `SPI_IOC_MESSAGE` `ioctl` +//! that queues up multiple SPI messages by writing an entire array of `spi_ioc_transfer` structs. +//! `linux/spi/spidev.h` defines a macro to calculate the `ioctl` number like: +//! +//! ```C +//! #define SPI_IOC_MAGIC 'k' +//! #define SPI_MSGSIZE(N) ... +//! #define SPI_IOC_MESSAGE(N) _IOW(SPI_IOC_MAGIC, 0, char[SPI_MSGSIZE(N)]) +//! ``` +//! +//! The `SPI_MSGSIZE(N)` calculation is already handled by the `ioctl_*!` macros, so all that's +//! needed to define this `ioctl` is: +//! +//! ``` +//! # #[macro_use] extern crate nix; +//! const SPI_IOC_MAGIC: u8 = b'k'; // Defined in linux/spi/spidev.h +//! const SPI_IOC_TYPE_MESSAGE: u8 = 0; +//! # pub struct spi_ioc_transfer(u64); +//! ioctl_write_buf!(spi_transfer, SPI_IOC_MAGIC, SPI_IOC_TYPE_MESSAGE, spi_ioc_transfer); +//! # fn main() {} +//! ``` +//! +//! This generates a function like: +//! +//! ``` +//! # #[macro_use] extern crate nix; +//! # use std::mem; +//! # use nix::{libc, Result}; +//! # use nix::errno::Errno; +//! # use nix::libc::c_int as c_int; +//! # const SPI_IOC_MAGIC: u8 = b'k'; +//! # const SPI_IOC_TYPE_MESSAGE: u8 = 0; +//! # pub struct spi_ioc_transfer(u64); +//! pub unsafe fn spi_message(fd: c_int, data: &mut [spi_ioc_transfer]) -> Result { +//! let res = libc::ioctl(fd, +//! request_code_write!(SPI_IOC_MAGIC, SPI_IOC_TYPE_MESSAGE, data.len() * mem::size_of::()), +//! data); +//! Errno::result(res) +//! } +//! # fn main() {} +//! ``` +//! +//! Finding `ioctl` Documentation +//! ----------------------------- +//! +//! For Linux, look at your system's headers. For example, `/usr/include/linux/input.h` has a lot +//! of lines defining macros which use `_IO`, `_IOR`, `_IOW`, `_IOC`, and `_IOWR`. Some `ioctl`s are +//! documented directly in the headers defining their constants, but others have more extensive +//! documentation in man pages (like termios' `ioctl`s which are in `tty_ioctl(4)`). +//! +//! Documenting the Generated Functions +//! =================================== +//! +//! In many cases, users will wish for the functions generated by the `ioctl` +//! macro to be public and documented. For this reason, the generated functions +//! are public by default. If you wish to hide the ioctl, you will need to put +//! them in a private module. +//! +//! For documentation, it is possible to use doc comments inside the `ioctl_*!` macros. Here is an +//! example : +//! +//! ``` +//! # #[macro_use] extern crate nix; +//! # use nix::libc::c_int; +//! ioctl_read! { +//! /// Make the given terminal the controlling terminal of the calling process. The calling +//! /// process must be a session leader and not have a controlling terminal already. If the +//! /// terminal is already the controlling terminal of a different session group then the +//! /// ioctl will fail with **EPERM**, unless the caller is root (more precisely: has the +//! /// **CAP_SYS_ADMIN** capability) and arg equals 1, in which case the terminal is stolen +//! /// and all processes that had it as controlling terminal lose it. +//! tiocsctty, b't', 19, c_int +//! } +//! +//! # fn main() {} +//! ``` +use cfg_if::cfg_if; + +#[cfg(any(target_os = "android", target_os = "linux", target_os = "redox"))] +#[macro_use] +mod linux; + +#[cfg(any( + target_os = "android", + target_os = "linux", + target_os = "redox" +))] +pub use self::linux::*; + +#[cfg(any( + target_os = "dragonfly", + target_os = "freebsd", + target_os = "illumos", + target_os = "ios", + target_os = "macos", + target_os = "netbsd", + target_os = "haiku", + target_os = "openbsd" +))] +#[macro_use] +mod bsd; + +#[cfg(any( + target_os = "dragonfly", + target_os = "freebsd", + target_os = "illumos", + target_os = "ios", + target_os = "macos", + target_os = "netbsd", + target_os = "haiku", + target_os = "openbsd" +))] +pub use self::bsd::*; + +/// Convert raw ioctl return value to a Nix result +#[macro_export] +#[doc(hidden)] +macro_rules!

An interface for controlling asynchronous communication ports +//! +//! This interface provides a safe wrapper around the termios subsystem defined by POSIX. The +//! underlying types are all implemented in libc for most platforms and either wrapped in safer +//! types here or exported directly. +//! +//! If you are unfamiliar with the `termios` API, you should first read the +//! [API documentation](https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/termios.h.html) and +//! then come back to understand how `nix` safely wraps it. +//! +//! It should be noted that this API incurs some runtime overhead above the base `libc` definitions. +//! As this interface is not used with high-bandwidth information, this should be fine in most +//! cases. The primary cost when using this API is that the `Termios` datatype here duplicates the +//! standard fields of the underlying `termios` struct and uses safe type wrappers for those fields. +//! This means that when crossing the FFI interface to the underlying C library, data is first +//! copied into the underlying `termios` struct, then the operation is done, and the data is copied +//! back (with additional sanity checking) into the safe wrapper types. The `termios` struct is +//! relatively small across all platforms (on the order of 32-64 bytes). +//! +//! The following examples highlight some of the API use cases such that users coming from using C +//! or reading the standard documentation will understand how to use the safe API exposed here. +//! +//! Example disabling processing of the end-of-file control character: +//! +//! ``` +//! # use self::nix::sys::termios::SpecialCharacterIndices::VEOF; +//! # use self::nix::sys::termios::{_POSIX_VDISABLE, Termios}; +//! # let mut termios: Termios = unsafe { std::mem::zeroed() }; +//! termios.control_chars[VEOF as usize] = _POSIX_VDISABLE; +//! ``` +//! +//! The flags within `Termios` are defined as bitfields using the `bitflags` crate. This provides +//! an interface for working with bitfields that is similar to working with the raw unsigned +//! integer types but offers type safety because of the internal checking that values will always +//! be a valid combination of the defined flags. +//! +//! An example showing some of the basic operations for interacting with the control flags: +//! +//! ``` +//! # use self::nix::sys::termios::{ControlFlags, Termios}; +//! # let mut termios: Termios = unsafe { std::mem::zeroed() }; +//! termios.control_flags & ControlFlags::CSIZE == ControlFlags::CS5; +//! termios.control_flags |= ControlFlags::CS5; +//! ``` +//! +//! # Baud rates +//! +//! This API is not consistent across platforms when it comes to `BaudRate`: Android and Linux both +//! only support the rates specified by the `BaudRate` enum through their termios API while the BSDs +//! support arbitrary baud rates as the values of the `BaudRate` enum constants are the same integer +//! value of the constant (`B9600` == `9600`). Therefore the `nix::termios` API uses the following +//! conventions: +//! +//! * `cfgetispeed()` - Returns `u32` on BSDs, `BaudRate` on Android/Linux +//! * `cfgetospeed()` - Returns `u32` on BSDs, `BaudRate` on Android/Linux +//! * `cfsetispeed()` - Takes `u32` or `BaudRate` on BSDs, `BaudRate` on Android/Linux +//! * `cfsetospeed()` - Takes `u32` or `BaudRate` on BSDs, `BaudRate` on Android/Linux +//! * `cfsetspeed()` - Takes `u32` or `BaudRate` on BSDs, `BaudRate` on Android/Linux +//! +//! The most common use case of specifying a baud rate using the enum will work the same across +//! platforms: +//! +//! ```rust +//! # use nix::sys::termios::{BaudRate, cfsetispeed, cfsetospeed, cfsetspeed, Termios}; +//! # fn main() { +//! # let mut t: Termios = unsafe { std::mem::zeroed() }; +//! cfsetispeed(&mut t, BaudRate::B9600).unwrap(); +//! cfsetospeed(&mut t, BaudRate::B9600).unwrap(); +//! cfsetspeed(&mut t, BaudRate::B9600).unwrap(); +//! # } +//! ``` +//! +//! Additionally round-tripping baud rates is consistent across platforms: +//! +//! ```rust +//! # use nix::sys::termios::{BaudRate, cfgetispeed, cfgetospeed, cfsetispeed, cfsetspeed, Termios}; +//! # fn main() { +//! # let mut t: Termios = unsafe { std::mem::zeroed() }; +//! # cfsetspeed(&mut t, BaudRate::B9600).unwrap(); +//! let speed = cfgetispeed(&t); +//! assert_eq!(speed, cfgetospeed(&t)); +//! cfsetispeed(&mut t, speed).unwrap(); +//! # } +//! ``` +//! +//! On non-BSDs, `cfgetispeed()` and `cfgetospeed()` both return a `BaudRate`: +//! +#![cfg_attr(any(target_os = "freebsd", target_os = "dragonfly", target_os = "ios", + target_os = "macos", target_os = "netbsd", target_os = "openbsd"), + doc = " ```rust,ignore")] +#![cfg_attr(not(any(target_os = "freebsd", target_os = "dragonfly", target_os = "ios", + target_os = "macos", target_os = "netbsd", target_os = "openbsd")), + doc = " ```rust")] +//! # use nix::sys::termios::{BaudRate, cfgetispeed, cfgetospeed, cfsetspeed, Termios}; +//! # fn main() { +//! # let mut t: Termios = unsafe { std::mem::zeroed() }; +//! # cfsetspeed(&mut t, BaudRate::B9600); +//! assert_eq!(cfgetispeed(&t), BaudRate::B9600); +//! assert_eq!(cfgetospeed(&t), BaudRate::B9600); +//! # } +//! ``` +//! +//! But on the BSDs, `cfgetispeed()` and `cfgetospeed()` both return `u32`s: +//! +#![cfg_attr(any(target_os = "freebsd", target_os = "dragonfly", target_os = "ios", + target_os = "macos", target_os = "netbsd", target_os = "openbsd"), + doc = " ```rust")] +#![cfg_attr(not(any(target_os = "freebsd", target_os = "dragonfly", target_os = "ios", + target_os = "macos", target_os = "netbsd", target_os = "openbsd")), + doc = " ```rust,ignore")] +//! # use nix::sys::termios::{BaudRate, cfgetispeed, cfgetospeed, cfsetspeed, Termios}; +//! # fn main() { +//! # let mut t: Termios = unsafe { std::mem::zeroed() }; +//! # cfsetspeed(&mut t, 9600u32); +//! assert_eq!(cfgetispeed(&t), 9600u32); +//! assert_eq!(cfgetospeed(&t), 9600u32); +//! # } +//! ``` +//! +//!

In a nutshell, API looks *roughly* like this: + +```rust +impl OnceCell { + fn new() -> OnceCell { ... } + fn set(&self, value: T) -> Result<(), T> { ... } + fn get(&self) -> Option<&T> { ... } +} +``` + +Note that, like with `RefCell` and `Mutex`, the `set` method requires only a shared reference. +Because of the single assignment restriction `get` can return an `&T` instead of `Ref` +or `MutexGuard`. + +`once_cell` also has a `Lazy` type, build on top of `OnceCell` which provides the same API as +the `lazy_static!` macro, but without using any macros: + +```rust +use std::{sync::Mutex, collections::HashMap}; +use once_cell::sync::Lazy; + +static GLOBAL_DATA: Lazy>> = Lazy::new(|| { + let mut m = HashMap::new(); + m.insert(13, "Spica".to_string()); + m.insert(74, "Hoyten".to_string()); + Mutex::new(m) +}); + +fn main() { + println!("{:?}", GLOBAL_DATA.lock().unwrap()); +} +``` + +More patterns and use-cases are in the [docs](https://docs.rs/once_cell/)! + +# Related crates + +* [double-checked-cell](https://github.com/niklasf/double-checked-cell) +* [lazy-init](https://crates.io/crates/lazy-init) +* [lazycell](https://crates.io/crates/lazycell) +* [mitochondria](https://crates.io/crates/mitochondria) +* [lazy_static](https://crates.io/crates/lazy_static) +* [async_once_cell](https://crates.io/crates/async_once_cell) +* [generic_once_cell](https://crates.io/crates/generic_once_cell) (bring your own mutex) + +The API of `once_cell` is being proposed for inclusion in +[`std`](https://github.com/rust-lang/rfcs/pull/2788). diff --git a/utshell-0.5.0/vendor/once_cell/bors.toml b/utshell-0.5.0/vendor/once_cell/bors.toml new file mode 100644 index 00000000..b92b99ac --- /dev/null +++ b/utshell-0.5.0/vendor/once_cell/bors.toml @@ -0,0 +1,2 @@ +status = [ "Rust" ] +delete_merged_branches = true diff --git a/utshell-0.5.0/vendor/once_cell/examples/bench.rs b/utshell-0.5.0/vendor/once_cell/examples/bench.rs new file mode 100644 index 00000000..e6801258 --- /dev/null +++ b/utshell-0.5.0/vendor/once_cell/examples/bench.rs @@ -0,0 +1,28 @@ +use std::mem::size_of; + +use once_cell::sync::OnceCell; + +const N_THREADS: usize = 32; +const N_ROUNDS: usize = 100_000_000; + +static CELL: OnceCell = OnceCell::new(); + +fn main() { + let start = std::time::Instant::now(); + let threads = + (0..N_THREADS).map(|i| std::thread::spawn(move || thread_main(i))).collect::>(); + for thread in threads { + thread.join().unwrap(); + } + println!("{:?}", start.elapsed()); + println!("size_of::>() = {:?}", size_of::>()); + println!("size_of::>() = {:?}", size_of::>()); + println!("size_of::>() = {:?}", size_of::>()); +} + +fn thread_main(i: usize) { + for _ in 0..N_ROUNDS { + let &value = CELL.get_or_init(|| i); + assert!(value < N_THREADS) + } +} diff --git a/utshell-0.5.0/vendor/once_cell/examples/bench_acquire.rs b/utshell-0.5.0/vendor/once_cell/examples/bench_acquire.rs new file mode 100644 index 00000000..15180474 --- /dev/null +++ b/utshell-0.5.0/vendor/once_cell/examples/bench_acquire.rs @@ -0,0 +1,39 @@ +//!

Ok(cfg.as_str()) +//! } +//! } +//! ``` +//! +//! ## Lazily Compiled Regex +//! +//! This is a `regex!` macro which takes a string literal and returns an +//! *expression* that evaluates to a `&'static Regex`: +//! +//! ``` +//! macro_rules! regex { +//! ($re:literal $(,)?) => {{ +//! static RE: once_cell::sync::OnceCell = once_cell::sync::OnceCell::new(); +//! RE.get_or_init(|| regex::Regex::new($re).unwrap()) +//! }}; +//! } +//! ``` +//! +//!

The `include_bytes` macro is useful to include test resources, but it slows +//! down test compilation a lot.

This crate's minimum supported `rustc` version is `1.56.0`. +//! +//! If only the `std` feature is enabled, MSRV will be updated conservatively, +//! supporting at least latest 8 versions of the compiler. When using other +//! features, like `parking_lot`, MSRV might be updated more frequently, up to +//! the latest stable. In both cases, increasing MSRV is *not* considered a +//! semver-breaking change. +//! +//! # Implementation details +//! +//! The implementation is based on the +//! [`lazy_static`](https://github.com/rust-lang-nursery/lazy-static.rs/) and +//! [`lazy_cell`](https://github.com/indiv0/lazycell/) crates and +//! [`std::sync::Once`]. In some sense, `once_cell` just streamlines and unifies +//! those APIs. +//! +//! To implement a sync flavor of `OnceCell`, this crates uses either a custom +//! re-implementation of `std::sync::Once` or `parking_lot::Mutex`. This is +//! controlled by the `parking_lot` feature (disabled by default). Performance +//! is the same for both cases, but the `parking_lot` based `OnceCell` is +//! smaller by up to 16 bytes. +//! +//! This crate uses `unsafe`. +//! +//! [`std::sync::Once`]: https://doc.rust-lang.org/std/sync/struct.Once.html +//! +//! # F.A.Q. +//! +//! **Should I use the sync or unsync flavor?** +//! +//! Because Rust compiler checks thread safety for you, it's impossible to +//! accidentally use `unsync` where `sync` is required. So, use `unsync` in +//! single-threaded code and `sync` in multi-threaded. It's easy to switch +//! between the two if code becomes multi-threaded later. +//! +//! At the moment, `unsync` has an additional benefit that reentrant +//! initialization causes a panic, which might be easier to debug than a +//! deadlock. +//! +//! **Does this crate support async?** +//! +//! No, but you can use +//! [`async_once_cell`](https://crates.io/crates/async_once_cell) instead. +//! +//! **Does this crate support `no_std`?** +//! +//! Yes, but with caveats. `OnceCell` is a synchronization primitive which +//! _semantically_ relies on blocking. `OnceCell` guarantees that at most one +//! `f` will be called to compute the value. If two threads of execution call +//! `get_or_init` concurrently, one of them has to wait. +//! +//! Waiting fundamentally requires OS support. Execution environment needs to +//! understand who waits on whom to prevent deadlocks due to priority inversion. +//! You _could_ make code to compile by blindly using pure spinlocks, but the +//! runtime behavior would be subtly wrong. +//! +//! Given these constraints, `once_cell` provides the following options: +//! +//! - The `race` module provides similar, but distinct synchronization primitive +//! which is compatible with `no_std`. With `race`, the `f` function can be +//! called multiple times by different threads, but only one thread will win +//! to install the value. +//! - `critical-section` feature (with a `-`, not `_`) uses `critical_section` +//! to implement blocking. +//! +//! **Can I bring my own mutex?** +//! +//! There is [generic_once_cell](https://crates.io/crates/generic_once_cell) to +//! allow just that. +//! +//! **Should I use `std::cell::OnceCell`, `once_cell`, or `lazy_static`?** +//! +//! If you can use `std` version (your MSRV is at least 1.70, and you don't need +//! extra features `once_cell` provides), use `std`. Otherwise, use `once_cell`. +//! Don't use `lazy_static`. +//! +//! # Related crates +//! +//! * Most of this crate's functionality is available in `std` starting with +//! Rust 1.70.

+//! +//! A wrapper around the procedural macro API of the compiler's [`proc_macro`] +//! crate. This library serves two purposes: +//! +//! [`proc_macro`]: https://doc.rust-lang.org/proc_macro/ +//! +//! - **Bring proc-macro-like functionality to other contexts like build.rs and +//! main.rs.** Types from `proc_macro` are entirely specific to procedural +//! macros and cannot ever exist in code outside of a procedural macro. +//! Meanwhile `proc_macro2` types may exist anywhere including non-macro code. +//! By developing foundational libraries like [syn] and [quote] against +//! `proc_macro2` rather than `proc_macro`, the procedural macro ecosystem +//! becomes easily applicable to many other use cases and we avoid +//! reimplementing non-macro equivalents of those libraries. +//! +//! - **Make procedural macros unit testable.** As a consequence of being +//! specific to procedural macros, nothing that uses `proc_macro` can be +//! executed from a unit test. In order for helper libraries or components of +//! a macro to be testable in isolation, they must be implemented using +//! `proc_macro2`. +//! +//! [syn]: https://github.com/dtolnay/syn +//! [quote]: https://github.com/dtolnay/quote +//! +//! # Usage +//! +//! The skeleton of a typical procedural macro typically looks like this: +//! +//! ``` +//! extern crate proc_macro; +//! +//! # const IGNORE: &str = stringify! { +//! #[proc_macro_derive(MyDerive)] +//! # }; +//! # #[cfg(wrap_proc_macro)] +//! pub fn my_derive(input: proc_macro::TokenStream) -> proc_macro::TokenStream { +//! let input = proc_macro2::TokenStream::from(input); +//! +//! let output: proc_macro2::TokenStream = { +//! /* transform input */ +//! # input +//! }; +//! +//! proc_macro::TokenStream::from(output) +//! } +//! ``` +//! +//! If parsing with [Syn], you'll use [`parse_macro_input!`] instead to +//! propagate parse errors correctly back to the compiler when parsing fails. +//! +//! [`parse_macro_input!`]: https://docs.rs/syn/2.0/syn/macro.parse_macro_input.html +//! +//! # Unstable features +//! +//! The default feature set of proc-macro2 tracks the most recent stable +//! compiler API. Functionality in `proc_macro` that is not yet stable is not +//! exposed by proc-macro2 by default. +//! +//! To opt into the additional APIs available in the most recent nightly +//! compiler, the `procmacro2_semver_exempt` config flag must be passed to +//! rustc. We will polyfill those nightly-only APIs back to Rust 1.56.0. As +//! these are unstable APIs that track the nightly compiler, minor versions of +//! proc-macro2 may make breaking changes to them at any time. +//! +//! ```sh +//! RUSTFLAGS='--cfg procmacro2_semver_exempt' cargo build +//! ``` +//! +//! Note that this must not only be done for your crate, but for any crate that +//! depends on your crate. This infectious nature is intentional, as it serves +//! as a reminder that you are outside of the normal semver guarantees. +//! +//! Semver exempt methods are marked as such in the proc-macro2 documentation. +//! +//! # Thread-Safety +//! +//!

We get all the benefits of the editor's brace matching, syntax +highlighting, indentation, and maybe autocompletion. But rather than compiling +that as code into the current crate, we can treat it as data, pass it around, +mutate it, and eventually hand it back to the compiler as tokens to compile into +the macro caller's crate. + +This crate is motivated by the procedural macro use case, but is a +general-purpose Rust quasi-quoting library and is not specific to procedural +macros. + +```toml +[dependencies] +quote = "1.0" +``` + +*Version requirement: Quote supports rustc 1.56 and up.*
+[*Release notes*](https://github.com/dtolnay/quote/releases) + +
+ +## Syntax + +The quote crate provides a [`quote!`] macro within which you can write Rust code +that gets packaged into a [`TokenStream`] and can be treated as data. You should +think of `TokenStream` as representing a fragment of Rust source code. + +[`TokenStream`]: https://docs.rs/proc-macro2/1.0/proc_macro2/struct.TokenStream.html + +Within the `quote!` macro, interpolation is done with `#var`. Any type +implementing the [`quote::ToTokens`] trait can be interpolated. This includes +most Rust primitive types as well as most of the syntax tree types from [`syn`]. + +[`quote::ToTokens`]: https://docs.rs/quote/1.0/quote/trait.ToTokens.html +[`syn`]: https://github.com/dtolnay/syn + +```rust +let tokens = quote! { + struct SerializeWith #generics #where_clause { + value: &'a #field_ty, + phantom: core::marker::PhantomData<#item_ty>, + } + + impl #generics serde::Serialize for SerializeWith #generics #where_clause { + fn serialize(&self, serializer: S) -> Result + where + S: serde::Serializer, + { + #path(self.value, serializer) + } + } + + SerializeWith { + value: #value, + phantom: core::marker::PhantomData::<#item_ty>, + } +}; +``` + +
+ +## Repetition + +Repetition is done using `#(...)*` or `#(...),*` similar to `macro_rules!`. This +iterates through the elements of any variable interpolated within the repetition +and inserts a copy of the repetition body for each one. The variables in an +interpolation may be anything that implements `IntoIterator`, including `Vec` or +a pre-existing iterator. + +- `#(#var)*` — no separators +- `#(#var),*` — the character before the asterisk is used as a separator +- `#( struct #var; )*` — the repetition can contain other things +- `#( #k => println!("{}", #v), )*` — even multiple interpolations + +Note that there is a difference between `#(#var ,)*` and `#(#var),*`—the latter +does not produce a trailing comma. This matches the behavior of delimiters in +`macro_rules!`. + +
+ +## Returning tokens to the compiler + +The `quote!` macro evaluates to an expression of type +`proc_macro2::TokenStream`. Meanwhile Rust procedural macros are expected to +return the type `proc_macro::TokenStream`. + +The difference between the two types is that `proc_macro` types are entirely +specific to procedural macros and cannot ever exist in code outside of a +procedural macro, while `proc_macro2` types may exist anywhere including tests +and non-macro code like main.rs and build.rs. This is why even the procedural +macro ecosystem is largely built around `proc_macro2`, because that ensures the +libraries are unit testable and accessible in non-macro contexts. + +There is a [`From`]-conversion in both directions so returning the output of +`quote!` from a procedural macro usually looks like `tokens.into()` or +`proc_macro::TokenStream::from(tokens)`. + +[`From`]: https://doc.rust-lang.org/std/convert/trait.From.html + +
+ +## Examples + +### Combining quoted fragments + +Usually you don't end up constructing an entire final `TokenStream` in one +piece. Different parts may come from different helper functions. The tokens +produced by `quote!` themselves implement `ToTokens` and so can be interpolated +into later `quote!` invocations to build up a final result. + +```rust +let type_definition = quote! {...}; +let methods = quote! {...}; + +let tokens = quote! { + #type_definition + #methods +}; +``` + +### Constructing identifiers + +Suppose we have an identifier `ident` which came from somewhere in a macro +input and we need to modify it in some way for the macro output. Let's consider +prepending the identifier with an underscore. + +Simply interpolating the identifier next to an underscore will not have the +behavior of concatenating them. The underscore and the identifier will continue +to be two separate tokens as if you had written `_ x`. + +```rust +// incorrect +quote! { + let mut _#ident = 0; +} +``` + +The solution is to build a new identifier token with the correct value. As this +is such a common case, the `format_ident!` macro provides a convenient utility +for doing so correctly. + +```rust +let varname = format_ident!("_{}", ident); +quote! { + let mut #varname = 0; +} +``` + +Alternatively, the APIs provided by Syn and proc-macro2 can be used to directly +build the identifier. This is roughly equivalent to the above, but will not +handle `ident` being a raw identifier. + +```rust +let concatenated = format!("_{}", ident); +let varname = syn::Ident::new(&concatenated, ident.span()); +quote! { + let mut #varname = 0; +} +``` + +### Making method calls + +Let's say our macro requires some type specified in the macro input to have a +constructor called `new`. We have the type in a variable called `field_type` of +type `syn::Type` and want to invoke the constructor. + +```rust +// incorrect +quote! { + let value = #field_type::new(); +} +``` + +This works only sometimes. If `field_type` is `String`, the expanded code +contains `String::new()` which is fine. But if `field_type` is something like +`Vec` then the expanded code is `Vec::new()` which is invalid syntax. +Ordinarily in handwritten Rust we would write `Vec::::new()` but for macros +often the following is more convenient. + +```rust +quote! { + let value = <#field_type>::new(); +} +``` + +This expands to `>::new()` which behaves correctly. + +A similar pattern is appropriate for trait methods. + +```rust +quote! { + let value = <#field_type as core::default::Default>::default(); +} +``` + +
+ +## Hygiene + +Any interpolated tokens preserve the `Span` information provided by their +`ToTokens` implementation. Tokens that originate within a `quote!` invocation +are spanned with [`Span::call_site()`]. + +[`Span::call_site()`]: https://docs.rs/proc-macro2/1.0/proc_macro2/struct.Span.html#method.call_site + +A different span can be provided explicitly through the [`quote_spanned!`] +macro. + +[`quote_spanned!`]: https://docs.rs/quote/1.0/quote/macro.quote_spanned.html + +
+ +## Non-macro code generators + +When using `quote` in a build.rs or main.rs and writing the output out to a +file, consider having the code generator pass the tokens through [prettyplease] +before writing.

+//! +//! This crate provides the [`quote!`] macro for turning Rust syntax tree data +//! structures into tokens of source code. +//! +//! [`quote!`]: macro.quote.html +//! +//! Procedural macros in Rust receive a stream of tokens as input, execute +//! arbitrary Rust code to determine how to manipulate those tokens, and produce +//! a stream of tokens to hand back to the compiler to compile into the caller's +//! crate. Quasi-quoting is a solution to one piece of that — producing +//! tokens to return to the compiler. +//! +//! The idea of quasi-quoting is that we write *code* that we treat as *data*. +//! Within the `quote!` macro, we can write what looks like code to our text +//! editor or IDE. We get all the benefits of the editor's brace matching, +//! syntax highlighting, indentation, and maybe autocompletion. But rather than +//! compiling that as code into the current crate, we can treat it as data, pass +//! it around, mutate it, and eventually hand it back to the compiler as tokens +//! to compile into the macro caller's crate. +//! +//! This crate is motivated by the procedural macro use case, but is a +//! general-purpose Rust quasi-quoting library and is not specific to procedural +//! macros. +//! +//! ```toml +//! [dependencies] +//! quote = "1.0" +//! ``` +//! +//!
+//! +//! # Example +//! +//! The following quasi-quoted block of code is something you might find in [a] +//! procedural macro having to do with data structure serialization. The `#var` +//! syntax performs interpolation of runtime variables into the quoted tokens. +//! Check out the documentation of the [`quote!`] macro for more detail about +//! the syntax. See also the [`quote_spanned!`] macro which is important for +//! implementing hygienic procedural macros. +//! +//! [a]: https://serde.rs/ +//! [`quote_spanned!`]: macro.quote_spanned.html +//! +//! ``` +//! # use quote::quote; +//! # +//! # let generics = ""; +//! # let where_clause = ""; +//! # let field_ty = ""; +//! # let item_ty = ""; +//! # let path = ""; +//! # let value = ""; +//! # +//! let tokens = quote! { +//! struct SerializeWith #generics #where_clause { +//! value: &'a #field_ty, +//! phantom: core::marker::PhantomData<#item_ty>, +//! } +//! +//! impl #generics serde::Serialize for SerializeWith #generics #where_clause { +//! fn serialize(&self, serializer: S) -> Result +//! where +//!

+/// +/// # Interpolation +/// +/// Variable interpolation is done with `#var` (similar to `$var` in +/// `macro_rules!` macros).

This includes most +/// Rust primitive types as well as most of the syntax tree types from the [Syn] +/// crate. +/// +/// [`ToTokens`]: trait.ToTokens.html +/// [Syn]: https://github.com/dtolnay/syn +/// +/// Repetition is done using `#(...)*` or `#(...),*` again similar to +/// `macro_rules!`. This iterates through the elements of any variable +/// interpolated within the repetition and inserts a copy of the repetition body +/// for each one.

+/// +/// # Hygiene +/// +/// Any interpolated tokens preserve the `Span` information provided by their +/// `ToTokens` implementation. Tokens that originate within the `quote!` +/// invocation are spanned with [`Span::call_site()`]. +/// +/// [`Span::call_site()`]: https://docs.rs/proc-macro2/1.0/proc_macro2/struct.Span.html#method.call_site +/// +/// A different span can be provided through the [`quote_spanned!`] macro. +/// +/// [`quote_spanned!`]: macro.quote_spanned.html +/// +///
+/// +/// # Return type +/// +/// The macro evaluates to an expression of type `proc_macro2::TokenStream`. +/// Meanwhile Rust procedural macros are expected to return the type +/// `proc_macro::TokenStream`. +/// +/// The difference between the two types is that `proc_macro` types are entirely +/// specific to procedural macros and cannot ever exist in code outside of a +/// procedural macro, while `proc_macro2` types may exist anywhere including +/// tests and non-macro code like main.rs and build.rs. This is why even the +/// procedural macro ecosystem is largely built around `proc_macro2`, because +/// that ensures the libraries are unit testable and accessible in non-macro +/// contexts. +/// +/// There is a [`From`]-conversion in both directions so returning the output of +/// `quote!` from a procedural macro usually looks like `tokens.into()` or +/// `proc_macro::TokenStream::from(tokens)`. +/// +/// [`From`]: https://doc.rust-lang.org/std/convert/trait.From.html +/// +///
+/// +/// # Examples +/// +/// ### Procedural macro +/// +/// The structure of a basic procedural macro is as follows. Refer to the [Syn] +/// crate for further useful guidance on using `quote!` as part of a procedural +/// macro. +/// +/// [Syn]: https://github.com/dtolnay/syn +/// +/// ``` +/// # #[cfg(any())] +/// extern crate proc_macro; +/// # extern crate proc_macro2; +/// +/// # #[cfg(any())] +/// use proc_macro::TokenStream; +/// # use proc_macro2::TokenStream; +/// use quote::quote; +/// +/// # const IGNORE_TOKENS: &'static str = stringify! { +/// #[proc_macro_derive(HeapSize)] +/// # }; +/// pub fn derive_heap_size(input: TokenStream) -> TokenStream { +/// // Parse the input and figure out what implementation to generate... +/// # const IGNORE_TOKENS: &'static str = stringify! { +/// let name = /* ... */; +/// let expr = /* ... */; +/// # }; +/// # +/// # let name = 0; +/// # let expr = 0; +/// +/// let expanded = quote! { +/// // The generated impl. +/// impl heapsize::HeapSize for #name { +/// fn heap_size_of_children(&self) -> usize { +/// #expr +/// } +/// } +/// }; +/// +/// // Hand the output tokens back to the compiler. +/// TokenStream::from(expanded) +/// } +/// ``` +/// +///


+/// +/// ### Combining quoted fragments +/// +/// Usually you don't end up constructing an entire final `TokenStream` in one +/// piece. Different parts may come from different helper functions. The tokens +/// produced by `quote!` themselves implement `ToTokens` and so can be +/// interpolated into later `quote!` invocations to build up a final result. +/// +/// ``` +/// # use quote::quote; +/// # +/// let type_definition = quote! {...}; +/// let methods = quote! {...}; +/// +/// let tokens = quote! { +/// #type_definition +/// #methods +/// }; +/// ``` +/// +///


+/// +/// ### Constructing identifiers +/// +/// Suppose we have an identifier `ident` which came from somewhere in a macro +/// input and we need to modify it in some way for the macro output. Let's +/// consider prepending the identifier with an underscore. +/// +/// Simply interpolating the identifier next to an underscore will not have the +/// behavior of concatenating them. The underscore and the identifier will +/// continue to be two separate tokens as if you had written `_ x`. +/// +/// ``` +/// # use proc_macro2::{self as syn, Span}; +/// # use quote::quote; +/// # +/// # let ident = syn::Ident::new("i", Span::call_site()); +/// # +/// // incorrect +/// quote! { +/// let mut _#ident = 0; +/// } +/// # ; +/// ``` +/// +/// The solution is to build a new identifier token with the correct value. As +/// this is such a common case, the [`format_ident!`] macro provides a +/// convenient utility for doing so correctly. +/// +/// ``` +/// # use proc_macro2::{Ident, Span}; +/// # use quote::{format_ident, quote}; +/// # +/// # let ident = Ident::new("i", Span::call_site()); +/// # +/// let varname = format_ident!("_{}", ident); +/// quote! { +/// let mut #varname = 0; +/// } +/// # ; +/// ``` +/// +/// Alternatively, the APIs provided by Syn and proc-macro2 can be used to +/// directly build the identifier. This is roughly equivalent to the above, but +/// will not handle `ident` being a raw identifier. +/// +/// ``` +/// # use proc_macro2::{self as syn, Span}; +/// # use quote::quote; +/// # +/// # let ident = syn::Ident::new("i", Span::call_site()); +/// # +/// let concatenated = format!("_{}", ident); +/// let varname = syn::Ident::new(&concatenated, ident.span()); +/// quote! { +/// let mut #varname = 0; +/// } +/// # ; +/// ``` +/// +///


+/// +/// ### Making method calls +/// +/// Let's say our macro requires some type specified in the macro input to have +/// a constructor called `new`. We have the type in a variable called +/// `field_type` of type `syn::Type` and want to invoke the constructor. +/// +/// ``` +/// # use quote::quote; +/// # +/// # let field_type = quote!(...); +/// # +/// // incorrect +/// quote! { +/// let value = #field_type::new(); +/// } +/// # ; +/// ``` +/// +/// This works only sometimes. If `field_type` is `String`, the expanded code +/// contains `String::new()` which is fine. But if `field_type` is something +/// like `Vec` then the expanded code is `Vec::new()` which is invalid +/// syntax.

There's no need to be mean or rude. +* Respect that people have differences of opinion and that every design or implementation choice carries a trade-off and numerous costs. There is seldom a right answer. +* Please keep unstructured critique to a minimum. If you have solid ideas you want to experiment with, make a fork and see how it works. +* We will exclude you from interaction if you insult, demean or harass anyone. That is not welcome behavior. We interpret the term "harassment" as including the definition in the Citizen Code of Conduct; if you have any lack of clarity about what might be included in that concept, please read their definition. In particular, we don't tolerate behavior that excludes people in socially marginalized groups. +* Private harassment is also unacceptable. No matter who you are, if you feel you have been or are being harassed or made uncomfortable by a community member, please contact one of the channel ops or any of the [Rust moderation team][mod_team] immediately. Whether you're a regular contributor or a newcomer, we care about making this community a safe place for you and we've got your back. +* Likewise any spamming, trolling, flaming, baiting or other attention-stealing behavior is not welcome. + +## Moderation + + +These are the policies for upholding our community's standards of conduct. If you feel that a thread needs moderation, please contact the [Rust moderation team][mod_team]. + +1. Remarks that violate the Rust standards of conduct, including hateful, hurtful, oppressive, or exclusionary remarks, are not allowed. (Cursing is allowed, but never targeting another user, and never in a hateful manner.) +2. Remarks that moderators find inappropriate, whether listed in the code of conduct or not, are also not allowed. +3. Moderators will first respond to such remarks with a warning. +4. If the warning is unheeded, the user will be "kicked," i.e., kicked out of the communication channel to cool off. +5. If the user comes back and continues to make trouble, they will be banned, i.e., indefinitely excluded. +6. Moderators may choose at their discretion to un-ban the user if it was a first offense and they offer the offended party a genuine apology. +7. If a moderator bans someone and you think it was unjustified, please take it up with that moderator, or with a different moderator, **in private**. Complaints about bans in-channel are not allowed. +8. Moderators are held to a higher standard than other community members. If a moderator creates an inappropriate situation, they should expect less leeway than others. + +In the Rust community we strive to go the extra step to look out for each other. Don't just aim to be technically unimpeachable, try to be your best self. In particular, avoid flirting with offensive or sensitive issues, particularly if they're off-topic; this all too often leads to unnecessary fights, hurt feelings, and damaged trust; worse, it can drive people away from the community entirely. + +And if someone takes issue with something you said or did, resist the urge to be defensive. Just stop doing what it was they complained about and apologize. Even if you feel you were misinterpreted or unfairly accused, chances are good there was something you could've communicated better — remember that it's your responsibility to make your fellow Rustaceans comfortable. Everyone wants to get along and we are all here first and foremost because we want to talk about cool technology. You will find that people will be eager to assume good intent and forgive as long as you earn their trust. + +The enforcement policies listed above apply to all official Rust venues; including official IRC channels (#rust, #rust-internals, #rust-tools, #rust-libs, #rustc, #rust-beginners, #rust-docs, #rust-community, #rust-lang, and #cargo); GitHub repositories under rust-lang, rust-lang-nursery, and rust-lang-deprecated; and all forums under rust-lang.org (users.rust-lang.org, internals.rust-lang.org). For other projects adopting the Rust Code of Conduct, please contact the maintainers of those projects for enforcement. If you wish to use this code of conduct for your own project, consider explicitly mentioning your moderation policy or making a copy with your own moderation policy so as to avoid confusion. + +*Adapted from the [Node.js Policy on Trolling](http://blog.izs.me/post/30036893703/policy-on-trolling) as well as the [Contributor Covenant v1.3.0](https://www.contributor-covenant.org/version/1/3/0/).* + +[mod_team]: https://www.rust-lang.org/team.html#Moderation-team diff --git a/utshell-0.5.0/vendor/rustc-hash/Cargo.toml b/utshell-0.5.0/vendor/rustc-hash/Cargo.toml new file mode 100644 index 00000000..47330b7e --- /dev/null +++ b/utshell-0.5.0/vendor/rustc-hash/Cargo.toml @@ -0,0 +1,25 @@ +# THIS FILE IS AUTOMATICALLY GENERATED BY CARGO +# +# When uploading crates to the registry Cargo will automatically +# "normalize" Cargo.toml files for maximal compatibility +# with all versions of Cargo and also rewrite `path` dependencies +# to registry (e.g., crates.io) dependencies +# +# If you believe there's an error in this file please file an +# issue against the rust-lang/cargo repository.

This version of `self_cell` is a re-export of the `self_cell` version `1` +//! meant for backwards-compatibly allowing `0.10` users to get current and +//! future soundness fixes. If you are adding `self_cell` as a dependency, +//! please use an up-to-date version directly. +//! +//! # Overview +//! +//! `self_cell` provides one macro-rules macro: [`self_cell`][`self_cell!`]. With this macro +//! you can create self-referential structs that are safe-to-use in stable Rust, +//! without leaking the struct internal lifetime. +//! +//! In a nutshell, the API looks *roughly* like this: +//! +//! ```ignore +//! // User code: +//! +//! self_cell!( +//! struct NewStructName { +//! owner: Owner, +//! +//! #[covariant] +//! dependent: Dependent, +//! } +//! +//! impl {Debug} +//! ); +//! +//! // Generated by macro: +//! +//! struct NewStructName(...); +//! +//! impl NewStructName { +//! fn new( +//! owner: Owner, +//! dependent_builder: impl for<'a> FnOnce(&'a Owner) -> Dependent<'a> +//! ) -> NewStructName { ... } +//! fn borrow_owner<'a>(&'a self) -> &'a Owner { ... } +//! fn borrow_dependent<'a>(&'a self) -> &'a Dependent<'a> { ... } +//! } +//! +//! impl Debug for NewStructName { ... } +//! ``` +//! +//! Self-referential structs are currently not supported with safe vanilla Rust. +//! The only reasonable safe alternative is to have the user juggle 2 separate +//! data structures which is a mess. The library solution ouroboros is really +//! expensive to compile due to its use of procedural macros. +//! +//! This alternative is `no_std`, uses no proc-macros, some self contained +//! unsafe and works on stable Rust, and is miri tested. With a total of less +//! than 300 lines of implementation code, which consists mostly of type and +//! trait implementations, this crate aims to be a good minimal solution to the +//! problem of self-referential structs. +//! +//! It has undergone [community code +//! review](https://users.rust-lang.org/t/experimental-safe-to-use-proc-macro-free-self-referential-structs-in-stable-rust/52775) +//! from experienced Rust users. +//! +//! ### Fast compile times +//! +//! ```txt +//! $ rm -rf target && cargo +nightly build -Z timings +//! +//! Compiling self_cell v0.7.0 +//! Completed self_cell v0.7.0 in 0.2s +//! ``` +//! +//! Because it does **not** use proc-macros, and has 0 dependencies +//! compile-times are fast. +//! +//! Measurements done on a slow laptop. +//! +//! ### A motivating use case +//! +//! ```rust +//! use self_cell::self_cell; +//! +//! #[derive(Debug, Eq, PartialEq)] +//! struct Ast<'a>(pub Vec<&'a str>); +//! +//! self_cell!( +//! struct AstCell { +//! owner: String, +//! +//! #[covariant] +//! dependent: Ast, +//! } +//! +//! impl {Debug, Eq, PartialEq} +//! ); +//! +//! fn build_ast_cell(code: &str) -> AstCell { +//! // Create owning String on stack. +//! let pre_processed_code = code.trim().to_string(); +//! +//! // Move String into AstCell, then build Ast inplace. +//! AstCell::new( +//! pre_processed_code, +//! |code| Ast(code.split(' ').filter(|word| word.len() > 1).collect()) +//! ) +//! } +//! +//! fn main() { +//! let ast_cell = build_ast_cell("fox = cat + dog"); +//! +//! println!("ast_cell -> {:?}", &ast_cell); +//! println!("ast_cell.borrow_owner() -> {:?}", ast_cell.borrow_owner()); +//! println!("ast_cell.borrow_dependent().0[1] -> {:?}", ast_cell.borrow_dependent().0[1]); +//! } +//! ``` +//! +//! ```txt +//! $ cargo run +//! +//! ast_cell -> AstCell { owner: "fox = cat + dog", dependent: Ast(["fox", "cat", "dog"]) } +//! ast_cell.borrow_owner() -> "fox = cat + dog" +//! ast_cell.borrow_dependent().0[1] -> "cat" +//! ``` +//! +//! There is no way in safe Rust to have an API like `build_ast_cell`, as soon +//! as `Ast` depends on stack variables like `pre_processed_code` you can't +//! return the value out of the function anymore. You could move the +//! pre-processing into the caller but that gets ugly quickly because you can't +//! encapsulate things anymore. Note this is a somewhat niche use case, +//! self-referential structs should only be used when there is no good +//! alternative. +//! +//! Under the hood, it heap allocates a struct which it initializes first by +//! moving the owner value to it and then using the reference to this now +//! Pin/Immovable owner to construct the dependent inplace next to it. This +//! makes it safe to move the generated SelfCell but you have to pay for the +//! heap allocation. +//! +//! See the documentation for [`self_cell`][`self_cell!`] to dive further into the details. +//! +//! Or take a look at the advanced examples: +//! - [Example how to handle dependent construction that can +//! fail](https://github.com/Voultapher/self_cell/tree/main/examples/fallible_dependent_construction) +//! +//! - [How to build a lazy AST with +//! self_cell](https://github.com/Voultapher/self_cell/tree/main/examples/lazy_ast) +//! +//! - [How to use an owner type with +//! lifetime](https://github.com/Voultapher/self_cell/tree/main/examples/owner_with_lifetime) +//! +//! ### Min required rustc version +//! +//! By default the minimum required rustc version is 1.51. +//! +//! There is an optional feature you can enable called "old_rust" that enables +//! support down to rustc version 1.36.

Example: `struct +/// AstCell` or `pub struct AstCell`. `$Vis` can be used to mark the struct +/// and all functions implemented by the macro as public. +/// +/// `$(#[$StructMeta:meta])*` allows you specify further meta items for this +/// struct, eg. `#[doc(hidden)] struct AstCell`. +/// +/// - `$Owner:ty` Type of owner. This has to have a `'static` lifetime. Example: +/// `String`. +/// +/// - `$Dependent:ident` Name of the dependent type without specified lifetime. +/// This can't be a nested type name. As workaround either create a type alias +/// `type Dep<'a> = Option>;` or create a new-type `struct +/// Dep<'a>(Option>);`. Example: `Ast`. +/// +/// `$Covariance:ident` Marker declaring if `$Dependent` is +/// [covariant](https://doc.rust-lang.org/nightly/nomicon/subtyping.html). +/// Possible Values: +/// +/// * **covariant**: This generates the direct reference accessor function +/// `borrow_dependent`. This is only safe to do if this compiles `fn +/// _assert_covariance<'x: 'y, 'y>(x: &'y $Dependent<'x>) -> &'y $Dependent<'y> +/// {x}`. Otherwise you could choose a lifetime that is too short for types +/// with interior mutability like `Cell`, which can lead to UB in safe code. +/// Which would violate the promise of this library that it is safe-to-use. +/// If you accidentally mark a type that is not covariant as covariant, you +/// will get a compile time error. +/// +/// * **not_covariant**: This generates no additional code but you can use the +/// `with_dependent` function. See [How to build a lazy AST with +/// self_cell](https://github.com/Voultapher/self_cell/tree/main/examples/lazy_ast) +/// for a usage example. +/// +/// In both cases you can use the `with_dependent_mut` function to mutate the +/// dependent value. This is safe to do because notionally you are replacing +/// pointers to a value not the other way around. +/// +/// - `impl {$($AutomaticDerive:ident),*},` Optional comma separated list of +/// optional automatic trait implementations. Possible Values: +/// +/// * **Debug**: Prints the debug representation of owner and dependent. +/// Example: `AstCell { owner: "fox = cat + dog", dependent: Ast(["fox", +/// "cat", "dog"]) }` +/// +/// * **PartialEq**: Logic `*self.borrow_owner() == *other.borrow_owner()`, +/// this assumes that `Dependent<'a>::From<&'a Owner>` is deterministic, so +/// that only comparing owner is enough. +/// +/// * **Eq**: Will implement the trait marker `Eq` for `$StructName`. Beware +/// if you select this `Eq` will be implemented regardless if `$Owner` +/// implements `Eq`, that's an unfortunate technical limitation. +/// +/// * **Hash**: Logic `self.borrow_owner().hash(state);`, this assumes that +/// `Dependent<'a>::From<&'a Owner>` is deterministic, so that only hashing +/// owner is enough. +/// +/// All `AutomaticDerive` are optional and you can implement you own version +/// of these traits. The declared struct is part of your module and you are +/// free to implement any trait in any way you want. Access to the unsafe +/// internals is only possible via unsafe functions, so you can't accidentally +/// use them in safe code. +/// +/// There is limited nested cell support.

You can +/// use any lifetime name you want, except `_q` and only a single lifetime is +/// supported, and can only be used in the owner.

Pre-allocated storage for a uniform data type. +//! +//! `Slab` provides pre-allocated storage for a single data type. If many values +//! of a single type are being allocated, it can be more efficient to +//! pre-allocate the necessary storage. Since the size of the type is uniform, +//! memory fragmentation can be avoided. Storing, clearing, and lookup +//! operations become very cheap. +//! +//! While `Slab` may look like other Rust collections, it is not intended to be +//! used as a general purpose collection. The primary difference between `Slab` +//! and `Vec` is that `Slab` returns the key when storing the value. +//! +//! It is important to note that keys may be reused. In other words, once a +//! value associated with a given key is removed from a slab, that key may be +//! returned from future calls to `insert`. +//! +//! # Examples +//! +//! Basic storing and retrieval. +//! +//! ``` +//! # use slab::*; +//! let mut slab = Slab::new(); +//! +//! let hello = slab.insert("hello"); +//! let world = slab.insert("world"); +//! +//! assert_eq!(slab[hello], "hello"); +//! assert_eq!(slab[world], "world"); +//! +//! slab[world] = "earth"; +//! assert_eq!(slab[world], "earth"); +//! ``` +//! +//! Sometimes it is useful to be able to associate the key with the value being +//! inserted in the slab. This can be done with the `vacant_entry` API as such: +//! +//! ``` +//! # use slab::*; +//! let mut slab = Slab::new(); +//! +//! let hello = { +//! let entry = slab.vacant_entry(); +//! let key = entry.key(); +//! +//! entry.insert((key, "hello")); +//! key +//! }; +//! +//! assert_eq!(hello, slab[hello].0); +//! assert_eq!("hello", slab[hello].1); +//! ``` +//! +//! It is generally a good idea to specify the desired capacity of a slab at +//! creation time. Note that `Slab` will grow the internal capacity when +//! attempting to insert a new value once the existing capacity has been reached. +//! To avoid this, add a check. +//! +//! ``` +//! # use slab::*; +//! let mut slab = Slab::with_capacity(1024); +//! +//! // ... use the slab +//! +//! if slab.len() == slab.capacity() { +//! panic!("slab full"); +//! } +//! +//! slab.insert("the slab is not at capacity yet"); +//! ``` +//! +//! # Capacity and reallocation +//! +//! The capacity of a slab is the amount of space allocated for any future +//! values that will be inserted in the slab. This is not to be confused with +//! the *length* of the slab, which specifies the number of actual values +//! currently being inserted. If a slab's length is equal to its capacity, the +//! next value inserted into the slab will require growing the slab by +//! reallocating. +//! +//! For example, a slab with capacity 10 and length 0 would be an empty slab +//! with space for 10 more stored values. Storing 10 or fewer elements into the +//! slab will not change its capacity or cause reallocation to occur. However, +//! if the slab length is increased to 11 (due to another `insert`), it will +//! have to reallocate, which can be slow. For this reason, it is recommended to +//! use [`Slab::with_capacity`] whenever possible to specify how many values the +//! slab is expected to store. +//! +//! # Implementation +//! +//! `Slab` is backed by a `Vec` of slots. Each slot is either occupied or +//! vacant. `Slab` maintains a stack of vacant slots using a linked list. To +//! find a vacant slot, the stack is popped. When a slot is released, it is +//! pushed onto the stack. +//! +//! If there are no more available slots in the stack, then `Vec::reserve(1)` is +//! called and a new slot is created. +//! +//!

These are called "debugger visualizations" or "debugger +views". + +The Windows debuggers (WinDbg\CDB) support defining custom debugger visualizations using +the `Natvis` framework. To use Natvis, developers write XML documents using the natvis +schema that describe how debugger types should be displayed with the `.natvis` extension. +(See: https://docs.microsoft.com/en-us/visualstudio/debugger/create-custom-views-of-native-objects?view=vs-2019) +The Natvis files provide patterns which match type names a description of how to display +those types. + +The Natvis schema can be found either online (See: https://code.visualstudio.com/docs/cpp/natvis#_schema) +or locally at `\Xml\Schemas\1033\natvis.xsd`. + +The GNU debugger (GDB) supports defining custom debugger views using Pretty Printers. +Pretty printers are written as python scripts that describe how a type should be displayed +when loaded up in GDB/LLDB. (See: https://sourceware.org/gdb/onlinedocs/gdb/Pretty-Printing.html#Pretty-Printing) +The pretty printers provide patterns, which match type names, and for matching +types, describe how to display those types. (For writing a pretty printer, see: https://sourceware.org/gdb/onlinedocs/gdb/Writing-a-Pretty_002dPrinter.html#Writing-a-Pretty_002dPrinter). + +### Embedding Visualizers + +Through the use of the currently unstable `#[debugger_visualizer]` attribute, the `smallvec` +crate can embed debugger visualizers into the crate metadata. + +Currently the two types of visualizers supported are Natvis and Pretty printers. + +For Natvis files, when linking an executable with a crate that includes Natvis files, +the MSVC linker will embed the contents of all Natvis files into the generated `PDB`. + +For pretty printers, the compiler will encode the contents of the pretty printer +in the `.debug_gdb_scripts` section of the `ELF` generated. + +### Testing Visualizers + +The `smallvec` crate supports testing debugger visualizers defined for this crate. The entry point for +these tests are `tests/debugger_visualizer.rs`. These tests are defined using the `debugger_test` and +`debugger_test_parser` crates. The `debugger_test` crate is a proc macro crate which defines a +single proc macro attribute, `#[debugger_test]`. For more detailed information about this crate, +see https://crates.io/crates/debugger_test. The CI pipeline for the `smallvec` crate has been updated +to run the debugger visualizer tests to ensure debugger visualizers do not become broken/stale. + +The `#[debugger_test]` proc macro attribute may only be used on test functions and will run the +function under the debugger specified by the `debugger` meta item. + +This proc macro attribute has 3 required values: + +1. The first required meta item, `debugger`, takes a string value which specifies the debugger to launch. +2. The second required meta item, `commands`, takes a string of new line (`\n`) separated list of debugger +commands to run. +3. The third required meta item, `expected_statements`, takes a string of new line (`\n`) separated list of +statements that must exist in the debugger output. Pattern matching through regular expressions is also +supported by using the `pattern:` prefix for each expected statement. + +#### Example: + +```rust +#[debugger_test( + debugger = "cdb", + commands = "command1\ncommand2\ncommand3", + expected_statements = "statement1\nstatement2\nstatement3")] +fn test() { + +} +``` + +Using a multiline string is also supported, with a single debugger command/expected statement per line: + +```rust +#[debugger_test( + debugger = "cdb", + commands = " +command1 +command2 +command3", + expected_statements = " +statement1 +pattern:statement[0-9]+ +statement3")] +fn test() { + +} +``` + +In the example above, the second expected statement uses pattern matching through a regular expression +by using the `pattern:` prefix. + +#### Testing Locally + +Currently, only Natvis visualizations have been defined for the `smallvec` crate via `debug_metadata/smallvec.natvis`, +which means the `tests/debugger_visualizer.rs` tests need to be run on Windows using the `*-pc-windows-msvc` targets. +To run these tests locally, first ensure the debugging tools for Windows are installed or install them following +the steps listed here, [Debugging Tools for Windows](https://docs.microsoft.com/en-us/windows-hardware/drivers/debugger/). +Once the debugging tools have been installed, the tests can be run in the same manner as they are in the CI +pipeline. + +#### Note + +When running the debugger visualizer tests, `tests/debugger_visualizer.rs`, they need to be run consecutively +and not in parallel. This can be achieved by passing the flag `--test-threads=1` to rustc. This is due to +how the debugger tests are run. Each test marked with the `#[debugger_test]` attribute launches a debugger +and attaches it to the current test process. If tests are running in parallel, the test will try to attach +a debugger to the current process which may already have a debugger attached causing the test to fail. + +For example: + +``` +cargo test --test debugger_visualizer --features debugger_visualizer -- --test-threads=1 +``` diff --git a/utshell-0.5.0/vendor/smallvec/debug_metadata/smallvec.natvis b/utshell-0.5.0/vendor/smallvec/debug_metadata/smallvec.natvis new file mode 100644 index 00000000..8731860f --- /dev/null +++ b/utshell-0.5.0/vendor/smallvec/debug_metadata/smallvec.natvis @@ -0,0 +1,35 @@ + + + + + + + {{ len={len()} is_inline={is_inline()} }} + + is_inline() ? $T2 : capacity + len() + data_ptr() + + + len() + data_ptr() + + + + + + + + + {{ len={len()} is_inline={is_inline()} }} + + is_inline() ? $T2 : capacity + len() + + + len() + data_ptr() + + + + \ No newline at end of file diff --git a/utshell-0.5.0/vendor/smallvec/scripts/run_miri.sh b/utshell-0.5.0/vendor/smallvec/scripts/run_miri.sh new file mode 100644 index 00000000..010ceb06 --- /dev/null +++ b/utshell-0.5.0/vendor/smallvec/scripts/run_miri.sh @@ -0,0 +1,24 @@ +#!/usr/bin/bash + +set -ex + +# Clean out our target dir, which may have artifacts compiled by a version of +# rust different from the one we're about to download. +cargo clean + +# Install and run the latest version of nightly where miri built successfully. +# Taken from: https://github.com/rust-lang/miri#running-miri-on-ci + +MIRI_NIGHTLY=nightly-$(curl -s https://rust-lang.github.io/rustup-components-history/x86_64-unknown-linux-gnu/miri) +echo "Installing latest nightly with Miri: $MIRI_NIGHTLY" +rustup override unset +rustup default "$MIRI_NIGHTLY" + +rustup component add miri +cargo miri setup + +cargo miri test --verbose +cargo miri test --verbose --features union +cargo miri test --verbose --all-features + +rustup override set nightly diff --git a/utshell-0.5.0/vendor/smallvec/src/arbitrary.rs b/utshell-0.5.0/vendor/smallvec/src/arbitrary.rs new file mode 100644 index 00000000..cbdfcb0e --- /dev/null +++ b/utshell-0.5.0/vendor/smallvec/src/arbitrary.rs @@ -0,0 +1,19 @@ +use crate::{Array, SmallVec}; +use arbitrary::{Arbitrary, Unstructured}; + +impl<'a, A: Array> Arbitrary<'a> for SmallVec +where + ::Item: Arbitrary<'a>, +{ + fn arbitrary(u: &mut Unstructured<'a>) -> arbitrary::Result { + u.arbitrary_iter()?.collect() + } + + fn arbitrary_take_rest(u: Unstructured<'a>) -> arbitrary::Result { + u.arbitrary_take_rest_iter()?.collect() + } + + fn size_hint(depth: usize) -> (usize, Option) { + arbitrary::size_hint::and(::size_hint(depth), (0, None)) + } +} diff --git a/utshell-0.5.0/vendor/smallvec/src/lib.rs b/utshell-0.5.0/vendor/smallvec/src/lib.rs new file mode 100644 index 00000000..cadb5d8b --- /dev/null +++ b/utshell-0.5.0/vendor/smallvec/src/lib.rs @@ -0,0 +1,2471 @@ +// Licensed under the Apache License, Version 2.0 or the MIT license +// , at your +// option.

To use this feature add `features = ["union"]` in the `smallvec` section of Cargo.toml. +//! Note that this feature requires Rust 1.49. +//! +//! Tracking issue: [rust-lang/rust#55149](https://github.com/rust-lang/rust/issues/55149) +//! +//! ### `const_generics` +//! +//! **This feature requires Rust 1.51.** +//! +//! When this feature is enabled, `SmallVec` works with any arrays of any size, not just a fixed +//! list of sizes. +//! +//! ### `const_new` +//! +//! **This feature requires Rust 1.51.** +//! +//! This feature exposes the functions [`SmallVec::new_const`], [`SmallVec::from_const`], and [`smallvec_inline`] which enables the `SmallVec` to be initialized from a const context. +//! For details, see the +//! [Rust Reference](https://doc.rust-lang.org/reference/const_eval.html#const-functions). +//! +//! ### `drain_filter` +//! +//! **This feature is unstable.** It may change to match the unstable `drain_filter` method in libstd. +//! +//! Enables the `drain_filter` method, which produces an iterator that calls a user-provided +//! closure to determine which elements of the vector to remove and yield from the iterator. +//! +//! ### `drain_keep_rest` +//! +//! **This feature is unstable.** It may change to match the unstable `drain_keep_rest` method in libstd. +//! +//! Enables the `DrainFilter::keep_rest` method. +//! +//! ### `specialization` +//! +//! **This feature is unstable and requires a nightly build of the Rust toolchain.** +//! +//! When this feature is enabled, `SmallVec::from(slice)` has improved performance for slices +//! of `Copy` types. (Without this feature, you can use `SmallVec::from_slice` to get optimal +//! performance for `Copy` types.) +//! +//! Tracking issue: [rust-lang/rust#31844](https://github.com/rust-lang/rust/issues/31844) +//! +//! ### `may_dangle` +//! +//! **This feature is unstable and requires a nightly build of the Rust toolchain.** +//! +//! This feature makes the Rust compiler less strict about use of vectors that contain borrowed +//! references. For details, see the +//! [Rustonomicon](https://doc.rust-lang.org/1.42.0/nomicon/dropck.html#an-escape-hatch). +//! +//!

For example, this is implemented by Box, Vec, Rc, Arc and String, among others. Even when a Box is moved, the underlying storage remains at a fixed location. + +More specifically, implementors must ensure that the result of calling deref() is valid for the lifetime of the object, not just the lifetime of the borrow, and that the deref is valid even if the object is moved. Also, it must be valid even after invoking arbitrary &self methods or doing anything transitively accessible from &Self. If Self also implements DerefMut, the same restrictions apply to deref_mut() and it must remain valid if anything transitively accessible from the result of deref_mut() is mutated/called. Additionally, multiple calls to deref, (and deref_mut if implemented) must return the same address. No requirements are placed on &mut self methods other than deref_mut() and drop(), if applicable. + +Basically, it must be valid to convert the result of deref() to a pointer, and later dereference that pointer, as long as the original object is still live, even if it has been moved or &self methods have been called on it. If DerefMut is also implemented, it must be valid to get pointers from deref() and deref_mut() and dereference them while the object is live, as long as you don't simultaneously dereference both of them. + +Additionally, Deref and DerefMut implementations must not panic, but users of the trait are not allowed to rely on this fact (so that this restriction can be removed later without breaking backwards compatibility, should the need arise). + +Here are some examples to help illustrate the requirements for implementing this trait: + +``` +# use std::ops::Deref; +struct Foo(u8); +impl Deref for Foo { + type Target = u8; + fn deref(&self) -> &Self::Target { &self.0 } +} +``` + +Foo cannot implement StableDeref because the int will move when Foo is moved, invalidating the result of deref(). + +``` +# use std::ops::Deref; +struct Foo(Box); +impl Deref for Foo { + type Target = u8; + fn deref(&self) -> &Self::Target { &*self.0 } +} +``` + +Foo can safely implement StableDeref, due to the use of Box. + + +``` +# use std::ops::Deref; +# use std::ops::DerefMut; +# use std::rc::Rc; +#[derive(Clone)] +struct Foo(Rc); +impl Deref for Foo { + type Target = u8; + fn deref(&self) -> &Self::Target { &*self.0 } +} +impl DerefMut for Foo { + fn deref_mut(&mut self) -> &mut Self::Target { Rc::make_mut(&mut self.0) } +} +``` + +This is a simple implementation of copy-on-write: Foo's deref_mut will copy the underlying int if it is not uniquely owned, ensuring unique access at the point where deref_mut() returns. However, Foo cannot implement StableDeref because calling deref_mut(), followed by clone().deref() will result in mutable and immutable references to the same location. Note that if the DerefMut implementation were removed, Foo could safely implement StableDeref. Likewise, if the Clone implementation were removed, it would be safe to implement StableDeref, although Foo would not be very useful in that case, (without clones, the rc will always be uniquely owned). + + +``` +# use std::ops::Deref; +struct Foo; +impl Deref for Foo { + type Target = str; + fn deref(&self) -> &Self::Target { &"Hello" } +} +``` +Foo can safely implement StableDeref.

The syntax tree is rooted at [`syn::File`] which + represents a full source file, but there are other entry points that may be + useful to procedural macros including [`syn::Item`], [`syn::Expr`] and + [`syn::Type`]. + +- **Derives** — Of particular interest to derive macros is [`syn::DeriveInput`] + which is any of the three legal input items to a derive macro. An example + below shows using this type in a library that can derive implementations of a + user-defined trait. + +- **Parsing** — Parsing in Syn is built around [parser functions] with the + signature `fn(ParseStream) -> Result`. Every syntax tree node defined by + Syn is individually parsable and may be used as a building block for custom + syntaxes, or you may dream up your own brand new syntax without involving any + of our syntax tree types. + +- **Location information** — Every token parsed by Syn is associated with a + `Span` that tracks line and column information back to the source of that + token. These spans allow a procedural macro to display detailed error messages + pointing to all the right places in the user's code. There is an example of + this below. + +- **Feature flags** — Functionality is aggressively feature gated so your + procedural macros enable only what they need, and do not pay in compile time + for all the rest. + +[`syn::File`]: https://docs.rs/syn/2.0/syn/struct.File.html +[`syn::Item`]: https://docs.rs/syn/2.0/syn/enum.Item.html +[`syn::Expr`]: https://docs.rs/syn/2.0/syn/enum.Expr.html +[`syn::Type`]: https://docs.rs/syn/2.0/syn/enum.Type.html +[`syn::DeriveInput`]: https://docs.rs/syn/2.0/syn/struct.DeriveInput.html +[parser functions]: https://docs.rs/syn/2.0/syn/parse/index.html + +*Version requirement: Syn supports rustc 1.56 and up.* + +[*Release notes*](https://github.com/dtolnay/syn/releases) + +
+ +## Resources + +The best way to learn about procedural macros is by writing some. Consider +working through [this procedural macro workshop][workshop] to get familiar with +the different types of procedural macros. The workshop contains relevant links +into the Syn documentation as you work through each project. + +[workshop]: https://github.com/dtolnay/proc-macro-workshop + +
+ +## Example of a derive macro + +The canonical derive macro using Syn looks like this. We write an ordinary Rust +function tagged with a `proc_macro_derive` attribute and the name of the trait +we are deriving. Any time that derive appears in the user's code, the Rust +compiler passes their data structure as tokens into our macro. We get to execute +arbitrary Rust code to figure out what to do with those tokens, then hand some +tokens back to the compiler to compile into the user's crate. + +[`TokenStream`]: https://doc.rust-lang.org/proc_macro/struct.TokenStream.html + +```toml +[dependencies] +syn = "2.0" +quote = "1.0" + +[lib] +proc-macro = true +``` + +```rust +use proc_macro::TokenStream; +use quote::quote; +use syn::{parse_macro_input, DeriveInput}; + +#[proc_macro_derive(MyMacro)] +pub fn my_macro(input: TokenStream) -> TokenStream { + // Parse the input tokens into a syntax tree + let input = parse_macro_input!(input as DeriveInput); + + // Build the output, possibly using quasi-quotation + let expanded = quote! { + // ... + }; + + // Hand the output tokens back to the compiler + TokenStream::from(expanded) +} +``` + +The [`heapsize`] example directory shows a complete working implementation of a +derive macro. The example derives a `HeapSize` trait which computes an estimate +of the amount of heap memory owned by a value. + +[`heapsize`]: examples/heapsize + +```rust +pub trait HeapSize { + /// Total number of bytes of heap memory owned by `self`. + fn heap_size_of_children(&self) -> usize; +} +``` + +The derive macro allows users to write `#[derive(HeapSize)]` on data structures +in their program. + +```rust +#[derive(HeapSize)] +struct Demo<'a, T: ?Sized> { + a: Box, + b: u8, + c: &'a str, + d: String, +} +``` + +
+ +## Spans and error reporting + +The token-based procedural macro API provides great control over where the +compiler's error messages are displayed in user code. Consider the error the +user sees if one of their field types does not implement `HeapSize`. + +```rust +#[derive(HeapSize)] +struct Broken { + ok: String, + bad: std::thread::Thread, +} +``` + +By tracking span information all the way through the expansion of a procedural +macro as shown in the `heapsize` example, token-based macros in Syn are able to +trigger errors that directly pinpoint the source of the problem. + +```console +error[E0277]: the trait bound `std::thread::Thread: HeapSize` is not satisfied + --> src/main.rs:7:5 + | +7 | bad: std::thread::Thread, + | ^^^^^^^^^^^^^^^^^^^^^^^^ the trait `HeapSize` is not implemented for `std::thread::Thread` +``` + +
+ +## Parsing a custom syntax + +The [`lazy-static`] example directory shows the implementation of a +`functionlike!(...)` procedural macro in which the input tokens are parsed using +Syn's parsing API. + +[`lazy-static`]: examples/lazy-static + +The example reimplements the popular `lazy_static` crate from crates.io as a +procedural macro. + +```rust +lazy_static! { + static ref USERNAME: Regex = Regex::new("^[a-z0-9_-]{3,16}$").unwrap(); +} +``` + +The implementation shows how to trigger custom warnings and error messages on +the macro input. + +```console +warning: come on, pick a more creative name + --> src/main.rs:10:16 + | +10 | static ref FOO: String = "lazy_static".to_owned(); + | ^^^ +``` + +
+ +## Testing + +When testing macros, we often care not just that the macro can be used +successfully but also that when the macro is provided with invalid input it +produces maximally helpful error messages. Consider using the [`trybuild`] crate +to write tests for errors that are emitted by your macro or errors detected by +the Rust compiler in the expanded code following misuse of the macro. Such tests +help avoid regressions from later refactors that mistakenly make an error no +longer trigger or be less helpful than it used to be. + +[`trybuild`]: https://github.com/dtolnay/trybuild + +
+ +## Debugging + +When developing a procedural macro it can be helpful to look at what the +generated code looks like. Use `cargo rustc -- -Zunstable-options +--pretty=expanded` or the [`cargo expand`] subcommand. + +[`cargo expand`]: https://github.com/dtolnay/cargo-expand + +To show the expanded code for some crate that uses your procedural macro, run +`cargo expand` from that crate. To show the expanded code for one of your own +test cases, run `cargo expand --test the_test_case` where the last argument is +the name of the test file without the `.rs` extension. + +This write-up by Brandon W Maister discusses debugging in more detail: +[Debugging Rust's new Custom Derive system][debugging]. + +[debugging]: https://quodlibetor.github.io/posts/debugging-rusts-new-custom-derive-system/ + +
+ +## Optional features + +Syn puts a lot of functionality behind optional features in order to optimize +compile time for the most common use cases. The following features are +available. + +- **`derive`** *(enabled by default)* — Data structures for representing the + possible input to a derive macro, including structs and enums and types. +- **`full`** — Data structures for representing the syntax tree of all valid + Rust source code, including items and expressions. +- **`parsing`** *(enabled by default)* — Ability to parse input tokens into a + syntax tree node of a chosen type. +- **`printing`** *(enabled by default)* — Ability to print a syntax tree node as + tokens of Rust source code. +- **`visit`** — Trait for traversing a syntax tree. +- **`visit-mut`** — Trait for traversing and mutating in place a syntax tree. +- **`fold`** — Trait for transforming an owned syntax tree. +- **`clone-impls`** *(enabled by default)* — Clone impls for all syntax tree + types. +- **`extra-traits`** — Debug, Eq, PartialEq, Hash impls for all syntax tree + types. +- **`proc-macro`** *(enabled by default)* — Runtime dependency on the dynamic + library libproc_macro from rustc toolchain. + +
+ +## Proc macro shim + +Syn operates on the token representation provided by the [proc-macro2] crate +from crates.io rather than using the compiler's built in proc-macro crate +directly. This enables code using Syn to execute outside of the context of a +procedural macro, such as in unit tests or build.rs, and we avoid needing +incompatible ecosystems for proc macros vs non-macro use cases. + +In general all of your code should be written against proc-macro2 rather than +proc-macro. The one exception is in the signatures of procedural macro entry +points, which are required by the language to use `proc_macro::TokenStream`. + +The proc-macro2 crate will automatically detect and use the compiler's data +structures when a procedural macro is active. + +[proc-macro2]: https://docs.rs/proc-macro2/1.0/proc_macro2/ + +
