By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Lesser General Public License instead.) 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 +this service 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 make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. 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. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute 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 and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +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 +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the 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 a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11.

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. + + 12.

It is safest +to attach them to the start of each source file to most effectively +convey 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 2 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, write to the Free Software Foundation, Inc., + 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author + Gnomovision 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, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary.

It also counts + as the successor of the GNU Library Public License, version 2, hence + the version number 2.1.] + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +Licenses are intended to guarantee your freedom to share and change +free software--to make sure the software is free for all its users. + + This license, the Lesser General Public License, applies to some +specially designated software packages--typically libraries--of the +Free Software Foundation and other authors who decide to use it. You +can use it too, but we suggest you first think carefully about whether +this license or the ordinary General Public License is the better +strategy to use in any particular case, based on the explanations +below. + + When we speak of free software, we are referring to freedom of use, +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 this service if you wish); that you receive source code or can get +it if you want it; that you can change the software and use pieces of +it in new free programs; and that you are informed that you can do +these things. + + To protect your rights, we need to make restrictions that forbid +distributors to deny you these rights or to ask you to surrender these +rights. These restrictions translate to certain responsibilities for +you if you distribute copies of the library or if you modify it. + + For example, if you distribute copies of the library, whether gratis +or for a fee, you must give the recipients all the rights that we gave +you. You must make sure that they, too, receive or can get the source +code. If you link other code with the library, you must provide +complete object files to the recipients, so that they can relink them +with the library after making changes to the library and recompiling +it. And you must show them these terms so they know their rights. + + We protect your rights with a two-step method: (1) we copyright the +library, and (2) we offer you this license, which gives you legal +permission to copy, distribute and/or modify the library. + + To protect each distributor, we want to make it very clear that +there is no warranty for the free library. Also, if the library is +modified by someone else and passed on, the recipients should know +that what they have is not the original version, so that the original +author's reputation will not be affected by problems that might be +introduced by others. + + Finally, software patents pose a constant threat to the existence of +any free program. We wish to make sure that a company cannot +effectively restrict the users of a free program by obtaining a +restrictive license from a patent holder. Therefore, we insist that +any patent license obtained for a version of the library must be +consistent with the full freedom of use specified in this license. + + Most GNU software, including some libraries, is covered by the +ordinary GNU General Public License. This license, the GNU Lesser +General Public License, applies to certain designated libraries, and +is quite different from the ordinary General Public License. We use +this license for certain libraries in order to permit linking those +libraries into non-free programs. + + When a program is linked with a library, whether statically or using +a shared library, the combination of the two is legally speaking a +combined work, a derivative of the original library. The ordinary +General Public License therefore permits such linking only if the +entire combination fits its criteria of freedom. The Lesser General +Public License permits more lax criteria for linking other code with +the library. + + We call this license the "Lesser" General Public License because it +does Less to protect the user's freedom than the ordinary General +Public License. It also provides other free software developers Less +of an advantage over competing non-free programs. These disadvantages +are the reason we use the ordinary General Public License for many +libraries. However, the Lesser license provides advantages in certain +special circumstances. + + For example, on rare occasions, there may be a special need to +encourage the widest possible use of a certain library, so that it +becomes a de-facto standard. To achieve this, non-free programs must +be allowed to use the library. A more frequent case is that a free +library does the same job as widely used non-free libraries. In this +case, there is little to gain by limiting the free library to free +software only, so we use the Lesser General Public License. + + In other cases, permission to use a particular library in non-free +programs enables a greater number of people to use a large body of +free software. For example, permission to use the GNU C Library in +non-free programs enables many more people to use the whole GNU +operating system, as well as its variant, the GNU/Linux operating +system. + + Although the Lesser General Public License is Less protective of the +users' freedom, it does ensure that the user of a program that is +linked with the Library has the freedom and the wherewithal to run +that program using a modified version of the Library. + + The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +"work based on the library" and a "work that uses the library". The +former contains code derived from the library, whereas the latter must +be combined with the library in order to run. + + GNU LESSER GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library or other +program which contains a notice placed by the copyright holder or +other authorized party saying it may be distributed under the terms of +this Lesser General Public License (also called "this License"). +Each licensee is addressed as "you". + + A "library" means a collection of software functions and/or data +prepared so as to be conveniently linked with application programs +(which use some of those functions and data) to form executables. + + The "Library", below, refers to any such software library or work +which has been distributed under these terms. A "work based on the +Library" means either the Library or any derivative work under +copyright law: that is to say, a work containing the Library or a +portion of it, either verbatim or with modifications and/or translated +straightforwardly into another language. (Hereinafter, translation is +included without limitation in the term "modification".) + + "Source code" for a work means the preferred form of the work for +making modifications to it. For a library, complete source code means +all the source code for all modules it contains, plus any associated +interface definition files, plus the scripts used to control +compilation and installation of the library. + + Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running a program using the Library is not restricted, and output from +such a program is covered only if its contents constitute a work based +on the Library (independent of the use of the Library in a tool for +writing it). Whether that is true depends on what the Library does +and what the program that uses the Library does. + + 1. You may copy and distribute verbatim copies of the Library's +complete source code as you receive it, in any medium, provided that +you conspicuously and appropriately publish on each copy an +appropriate copyright notice and disclaimer of warranty; keep intact +all the notices that refer to this License and to the absence of any +warranty; and distribute a copy of this License along with the +Library. + + You may charge a fee for the physical act of transferring a copy, +and you may at your option offer warranty protection in exchange for a +fee. + + 2. You may modify your copy or copies of the Library or any portion +of it, thus forming a work based on the Library, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) The modified work must itself be a software library. + + b) You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. + + c) You must cause the whole of the work to be licensed at no + charge to all third parties under the terms of this License. + + d) If a facility in the modified Library refers to a function or a + table of data to be supplied by an application program that uses + the facility, other than as an argument passed when the facility + is invoked, then you must make a good faith effort to ensure that, + in the event an application does not supply such function or + table, the facility still operates, and performs whatever part of + its purpose remains meaningful. + + (For example, a function in a library to compute square roots has + a purpose that is entirely well-defined independent of the + application. Therefore, Subsection 2d requires that any + application-supplied function or table used by this function must + be optional: if the application does not supply it, the square + root function must still compute square roots.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Library, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Library, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote +it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Library. + +In addition, mere aggregation of another work not based on the Library +with the Library (or with a work based on the Library) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may opt to apply the terms of the ordinary GNU General Public +License instead of this License to a given copy of the Library. To do +this, you must alter all the notices that refer to this License, so +that they refer to the ordinary GNU General Public License, version 2, +instead of to this License. (If a newer version than version 2 of the +ordinary GNU General Public License has appeared, then you can specify +that version instead if you wish.) Do not make any other change in +these notices. + + Once this change is made in a given copy, it is irreversible for +that copy, so the ordinary GNU General Public License applies to all +subsequent copies and derivative works made from that copy. + + This option is useful when you wish to copy part of the code of +the Library into a program that is not a library. + + 4. You may copy and distribute the Library (or a portion or +derivative of it, under Section 2) in object code or executable form +under the terms of Sections 1 and 2 above provided that you accompany +it with the complete corresponding machine-readable source code, which +must be distributed under the terms of Sections 1 and 2 above on a +medium customarily used for software interchange. + + If distribution of object code is made by offering access to copy +from a designated place, then offering equivalent access to copy the +source code from the same place satisfies the requirement to +distribute the source code, even though third parties are not +compelled to copy the source along with the object code. + + 5. A program that contains no derivative of any portion of the +Library, but is designed to work with the Library by being compiled or +linked with it, is called a "work that uses the Library". Such a +work, in isolation, is not a derivative work of the Library, and +therefore falls outside the scope of this License. + + However, linking a "work that uses the Library" with the Library +creates an executable that is a derivative of the Library (because it +contains portions of the Library), rather than a "work that uses the +library". The executable is therefore covered by this License. +Section 6 states terms for distribution of such executables. + + When a "work that uses the Library" uses material from a header file +that is part of the Library, the object code for the work may be a +derivative work of the Library even though the source code is not. +Whether this is true is especially significant if the work can be +linked without the Library, or if the work is itself a library. The +threshold for this to be true is not precisely defined by law. + + If such an object file uses only numerical parameters, data +structure layouts and accessors, and small macros and small inline +functions (ten lines or less in length), then the use of the object +file is unrestricted, regardless of whether it is legally a derivative +work. (Executables containing this object code plus portions of the +Library will still fall under Section 6.) + + Otherwise, if the work is a derivative of the Library, you may +distribute the object code for the work under the terms of Section 6. +Any executables containing that work also fall under Section 6, +whether or not they are linked directly with the Library itself. + + 6. As an exception to the Sections above, you may also combine or +link a "work that uses the Library" with the Library to produce a +work containing portions of the Library, and distribute that work +under terms of your choice, provided that the terms permit +modification of the work for the customer's own use and reverse +engineering for debugging such modifications. + + You must give prominent notice with each copy of the work that the +Library is used in it and that the Library and its use are covered by +this License. You must supply a copy of this License. If the work +during execution displays copyright notices, you must include the +copyright notice for the Library among them, as well as a reference +directing the user to the copy of this License. Also, you must do one +of these things: + + a) Accompany the work with the complete corresponding + machine-readable source code for the Library including whatever + changes were used in the work (which must be distributed under + Sections 1 and 2 above); and, if the work is an executable linked + with the Library, with the complete machine-readable "work that + uses the Library", as object code and/or source code, so that the + user can modify the Library and then relink to produce a modified + executable containing the modified Library. (It is understood + that the user who changes the contents of definitions files in the + Library will not necessarily be able to recompile the application + to use the modified definitions.) + + b) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (1) uses at run time a + copy of the library already present on the user's computer system, + rather than copying library functions into the executable, and (2) + will operate properly with a modified version of the library, if + the user installs one, as long as the modified version is + interface-compatible with the version that the work was made with. + + c) Accompany the work with a written offer, valid for at least + three years, to give the same user the materials specified in + Subsection 6a, above, for a charge no more than the cost of + performing this distribution. + + d) If distribution of the work is made by offering access to copy + from a designated place, offer equivalent access to copy the above + specified materials from the same place. + + e) Verify that the user has already received a copy of these + materials or that you have already sent this user a copy. + + For an executable, the required form of the "work that uses the +Library" must include any data and utility programs needed for +reproducing the executable from it. However, as a special exception, +the materials to be distributed need not include anything that is +normally distributed (in either source or binary form) with the major +components (compiler, kernel, and so on) of the operating system on +which the executable runs, unless that component itself accompanies +the executable. + + It may happen that this requirement contradicts the license +restrictions of other proprietary libraries that do not normally +accompany the operating system. Such a contradiction means you cannot +use both them and the Library together in an executable that you +distribute. + + 7. You may place library facilities that are a work based on the +Library side-by-side in a single library together with other library +facilities not covered by this License, and distribute such a combined +library, provided that the separate distribution of the work based on +the Library and of the other library facilities is otherwise +permitted, and provided that you do these two things: + + a) Accompany the combined library with a copy of the same work + based on the Library, uncombined with any other library + facilities. This must be distributed under the terms of the + Sections above. + + b) Give prominent notice with the combined library of the fact + that part of it is a work based on the Library, and explaining + where to find the accompanying uncombined form of the same work. + + 8. You may not copy, modify, sublicense, link with, or distribute +the Library except as expressly provided under this License. Any +attempt otherwise to copy, modify, sublicense, link with, or +distribute the Library is void, and will automatically terminate your +rights under this License. However, parties who have received copies, +or rights, from you under this License will not have their licenses +terminated so long as such parties remain in full compliance. + + 9. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Library or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Library (or any work based on the +Library), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Library or works based on it. + + 10. Each time you redistribute the Library (or any work based on the +Library), the recipient automatically receives a license from the +original licensor to copy, distribute, link with or modify the Library +subject to these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties with +this License. + + 11. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +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 +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Library at all. For example, if a patent +license would not permit royalty-free redistribution of the Library by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Library. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply, and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 12. If the distribution and/or use of the Library is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Library under this License +may add an explicit geographical distribution limitation excluding those +countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 13. The Free Software Foundation may publish revised and/or new +versions of the Lesser 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 Library +specifies a version number of this License which applies to it and +"any later version", you have the option of following the terms and +conditions either of that version or of any later version published by +the Free Software Foundation. If the Library does not specify a +license version number, you may choose any version ever published by +the Free Software Foundation. + + 14. If you wish to incorporate parts of the Library into other free +programs whose distribution conditions are incompatible with these, +write to the author to ask for permission. For software which is +copyrighted by the Free Software Foundation, write to the Free +Software Foundation; we sometimes make exceptions for this. Our +decision will be guided by the two goals of preserving the free status +of all derivatives of our free software and of promoting the sharing +and reuse of software generally. + + NO WARRANTY + + 15.

It is currently the library powering pylint's capabilities. + +It provides a compatible representation which comes from the `_ast` +module. It rebuilds the tree generated by the builtin _ast module by +recursively walking down the AST and building an extended ast. The new +node classes have additional methods and attributes for different +usages. They include some support for static inference and local name +scopes. Furthermore, astroid can also build partial trees by inspecting living +objects. + + +Installation +------------ + +Extract the tarball, jump into the created directory and run:: + + pip install . + + +If you want to do an editable installation, you can run:: + + pip install -e . + + +If you have any questions, please mail the code-quality@python.org +mailing list for support.

bash + + wget https://raw.github.com/timothycrosley/isort/master/kate_plugin/isort_plugin_old.py --output-document ~/.kde/share/apps/kate/pate/isort_plugin.py + +You will then need to restart kate and enable Python Plugins as well as the isort plugin itself. + +Installing isort's for your preferred text editor +================================================= + +Several plugins have been written that enable to use isort from within a variety of text-editors. +You can find a full list of them `on the isort wiki `_. +Additionally, I will enthusiastically accept pull requests that include plugins for other text editors +and add documentation for them as I am notified. + +How does isort work? +==================== + +isort parses specified files for global level import lines (imports outside of try / except blocks, functions, etc..) +and puts them all at the top of the file grouped together by the type of import: + +- Future +- Python Standard Library +- Third Party +- Current Python Project +- Explicitly Local (. before import, as in: ``from . import x``) +- Custom Separate Sections (Defined by forced_separate list in configuration file) +- Custom Sections (Defined by sections list in configuration file) + +Inside of each section the imports are sorted alphabetically. isort automatically removes duplicate python imports, +and wraps long from imports to the specified line length (defaults to 79). + +When will isort not work? +========================= + +If you ever have the situation where you need to have a try / except block in the middle of top-level imports or if +your import order is directly linked to precedence. + +For example: a common practice in Django settings files is importing * from various settings files to form +a new settings file. In this case if any of the imports change order you are changing the settings definition itself. + +However, you can configure isort to skip over just these files - or even to force certain imports to the top. + +Configuring isort +================= + +If you find the default isort settings do not work well for your project, isort provides several ways to adjust +the behavior. + +To configure isort for a single user create a ``~/.isort.cfg`` or ``$XDG_CONFIG_HOME/isort.cfg`` file: + +.. code-block:: ini + + [settings] + line_length=120 + force_to_top=file1.py,file2.py + skip=file3.py,file4.py + known_future_library=future,pies + known_standard_library=std,std2 + known_third_party=randomthirdparty + known_first_party=mylib1,mylib2 + indent=' ' + multi_line_output=3 + length_sort=1 + forced_separate=django.contrib,django.utils + default_section=FIRSTPARTY + no_lines_before=LOCALFOLDER + +Additionally, you can specify project level configuration simply by placing a ``.isort.cfg`` file at the root of your +project. isort will look up to 25 directories up, from the file it is ran against, to find a project specific configuration. + +Or, if you prefer, you can add an ``isort`` or ``tool:isort`` section to your project's ``setup.cfg`` or ``tox.ini`` file with any desired settings. + +You can also add your desired settings under a ``[tool.isort]`` section in your ``pyproject.toml`` file. + +You can then override any of these settings by using command line arguments, or by passing in override values to the +SortImports class. + +Finally, as of version 3.0 isort supports editorconfig files using the standard syntax defined here: +https://editorconfig.org/ + +Meaning you place any standard isort configuration parameters within a .editorconfig file under the ``*.py`` section +and they will be honored. + +For a full list of isort settings and their meanings `take a look at the isort wiki `_. + +Multi line output modes +======================= + +You will notice above the "multi_line_output" setting. This setting defines how from imports wrap when they extend +past the line_length limit and has 6 possible settings: + +**0 - Grid** + +.. code-block:: python + + from third_party import (lib1, lib2, lib3, + lib4, lib5, ...) + +**1 - Vertical** + +.. code-block:: python + + from third_party import (lib1, + lib2, + lib3 + lib4, + lib5, + ...) + +**2 - Hanging Indent** + +.. code-block:: python + + from third_party import \ + lib1, lib2, lib3, \ + lib4, lib5, lib6 + +**3 - Vertical Hanging Indent** + +.. code-block:: python + + from third_party import ( + lib1, + lib2, + lib3, + lib4, + ) + +**4 - Hanging Grid** + +.. code-block:: python + + from third_party import ( + lib1, lib2, lib3, lib4, + lib5, ...) + +**5 - Hanging Grid Grouped** + +.. code-block:: python + + from third_party import ( + lib1, lib2, lib3, lib4, + lib5, ... + ) + +**6 - Hanging Grid Grouped, No Trailing Comma** + +In Mode 5 isort leaves a single extra space to maintain consistency of output when a comma is added at the end. +Mode 6 is the same - except that no extra space is maintained leading to the possibility of lines one character longer. +You can enforce a trailing comma by using this in conjunction with `-tc` or `trailing_comma: True`. + +.. code-block:: python + + from third_party import ( + lib1, lib2, lib3, lib4, + lib5 + ) + +**7 - NOQA** + +.. code-block:: python + + from third_party import lib1, lib2, lib3, ... # NOQA + +Alternatively, you can set ``force_single_line`` to ``True`` (``-sl`` on the command line) and every import will appear on its +own line: + +.. code-block:: python + + from third_party import lib1 + from third_party import lib2 + from third_party import lib3 + ... + +Note: to change the how constant indents appear - simply change the indent property with the following accepted formats: + +* Number of spaces you would like. For example: 4 would cause standard 4 space indentation. +* Tab +* A verbatim string with quotes around it. + +For example: + +.. code-block:: python + + " " + +is equivalent to 4. + +For the import styles that use parentheses, you can control whether or not to +include a trailing comma after the last import with the ``include_trailing_comma`` +option (defaults to ``False``). + +Intelligently Balanced Multi-line Imports +========================================= + +As of isort 3.1.0 support for balanced multi-line imports has been added. +With this enabled isort will dynamically change the import length to the one that produces the most balanced grid, +while staying below the maximum import length defined. + +Example: + +.. code-block:: python + + from __future__ import (absolute_import, division, + print_function, unicode_literals) + +Will be produced instead of: + +.. code-block:: python + + from __future__ import (absolute_import, division, print_function, + unicode_literals) + +To enable this set ``balanced_wrapping`` to ``True`` in your config or pass the ``-e`` option into the command line utility. + +Custom Sections and Ordering +============================ + +You can change the section order with ``sections`` option from the default of: + +.. code-block:: ini + + FUTURE,STDLIB,THIRDPARTY,FIRSTPARTY,LOCALFOLDER + +to your preference: + +.. code-block:: ini + + sections=FUTURE,STDLIB,FIRSTPARTY,THIRDPARTY,LOCALFOLDER + +You also can define your own sections and their order. + +Example: + +.. code-block:: ini + + known_django=django + known_pandas=pandas,numpy + sections=FUTURE,STDLIB,DJANGO,THIRDPARTY,PANDAS,FIRSTPARTY,LOCALFOLDER + +would create two new sections with the specified known modules. + +The ``no_lines_before`` option will prevent the listed sections from being split from the previous section by an empty line. + +Example: + +.. code-block:: ini + + sections=FUTURE,STDLIB,THIRDPARTY,FIRSTPARTY,LOCALFOLDER + no_lines_before=LOCALFOLDER + +would produce a section with both FIRSTPARTY and LOCALFOLDER modules combined. + +Auto-comment import sections +============================ + +Some projects prefer to have import sections uniquely titled to aid in identifying the sections quickly +when visually scanning. isort can automate this as well. To do this simply set the ``import_heading_{section_name}`` +setting for each section you wish to have auto commented - to the desired comment. + +For Example: + +.. code-block:: ini + + import_heading_stdlib=Standard Library + import_heading_firstparty=My Stuff + +Would lead to output looking like the following: + +.. code-block:: python + + # Standard Library + import os + import sys + + import django.settings + + # My Stuff + import myproject.test + +Ordering by import length +========================= + +isort also makes it easy to sort your imports by length, simply by setting the ``length_sort`` option to ``True``. +This will result in the following output style: + +.. code-block:: python + + from evn.util import ( + Pool, + Dict, + Options, + Constant, + DecayDict, + UnexpectedCodePath, + ) + +It is also possible to opt-in to sorting imports by length for only specific +sections by using ``length_sort_`` followed by the section name as a +configuration item, e.g.:: + + length_sort_stdlib=1 + +Skip processing of imports (outside of configuration) +===================================================== + +To make isort ignore a single import simply add a comment at the end of the import line containing the text ``isort:skip``: + +.. code-block:: python + + import module # isort:skip + +or: + +.. code-block:: python + + from xyz import (abc, # isort:skip + yo, + hey) + +To make isort skip an entire file simply add ``isort:skip_file`` to the module's doc string: + +.. code-block:: python + + """ my_module.py + Best module ever + + isort:skip_file + """ + + import b + import a + +Adding an import to multiple files +================================== + +isort makes it easy to add an import statement across multiple files, while being assured it's correctly placed. + +From the command line: + +.. code-block:: bash + + isort -a "from __future__ import print_function" *.py + +from within Kate: + +.. code-block:: + + ctrl+] + +or: + +.. code-block:: + + menu > Python > Add Import + +Removing an import from multiple files +====================================== + +isort also makes it easy to remove an import from multiple files, without having to be concerned with how it was originally +formatted. + +From the command line: + +.. code-block:: bash + + isort -rm "os.system" *.py + +from within Kate: + +.. code-block:: + + ctrl+shift+] + +or: + +.. code-block:: + + menu > Python > Remove Import + +Using isort to verify code +========================== + +The ``--check-only`` option +--------------------------- + +isort can also be used to used to verify that code is correctly formatted by running it with ``-c``. +Any files that contain incorrectly sorted and/or formatted imports will be outputted to ``stderr``. + +.. code-block:: bash + + isort **/*.py -c -vb + + SUCCESS: /home/timothy/Projects/Open_Source/isort/isort_kate_plugin.py Everything Looks Good! + ERROR: /home/timothy/Projects/Open_Source/isort/isort/isort.py Imports are incorrectly sorted. + +One great place this can be used is with a pre-commit git hook, such as this one by @acdha: + +https://gist.github.com/acdha/8717683 + +This can help to ensure a certain level of code quality throughout a project. + + +Git hook +-------- + +isort provides a hook function that can be integrated into your Git pre-commit script to check +Python code before committing. + +To cause the commit to fail if there are isort errors (strict mode), include the following in +``.git/hooks/pre-commit``: + +.. code-block:: python + + #!/usr/bin/env python + import sys + from isort.hooks import git_hook + + sys.exit(git_hook(strict=True, modify=True)) + +If you just want to display warnings, but allow the commit to happen anyway, call ``git_hook`` without +the `strict` parameter. If you want to display warnings, but not also fix the code, call ``git_hook`` without +the `modify` parameter. + +Setuptools integration +---------------------- + +Upon installation, isort enables a ``setuptools`` command that checks Python files +declared by your project. + +Running ``python setup.py isort`` on the command line will check the files +listed in your ``py_modules`` and ``packages``. If any warning is found, +the command will exit with an error code: + +.. code-block:: bash + + $ python setup.py isort + +Also, to allow users to be able to use the command without having to install +isort themselves, add isort to the setup_requires of your ``setup()`` like so: + +.. code-block:: python + + setup( + name="project", + packages=["project"], + + setup_requires=[ + "isort" + ] + ) + + +Why isort? +========== + +isort simply stands for import sort. It was originally called "sortImports" however I got tired of typing the extra +characters and came to the realization camelCase is not pythonic. + +I wrote isort because in an organization I used to work in the manager came in one day and decided all code must +have alphabetically sorted imports. The code base was huge - and he meant for us to do it by hand. However, being a +programmer - I'm too lazy to spend 8 hours mindlessly performing a function, but not too lazy to spend 16 +hours automating it. I was given permission to open source sortImports and here we are :) + +-------------------------------------------- + +Thanks and I hope you find isort useful! + +~Timothy Crosley + + diff --git a/Display/.venv/lib/python3.7/site-packages/isort-4.3.21.dist-info/RECORD b/Display/.venv/lib/python3.7/site-packages/isort-4.3.21.dist-info/RECORD new file mode 100644 index 0000000..cb32637 --- /dev/null +++ b/Display/.venv/lib/python3.7/site-packages/isort-4.3.21.dist-info/RECORD @@ -0,0 +1,30 @@ +../../../bin/isort,sha256=to4mIYHfI0M3oL8YpRUCSJA0z0j1NgaYeq3PHNUs1Q0,269 +isort-4.3.21.dist-info/INSTALLER,sha256=zuuue4knoyJ-UwPPXg8fezS7VCrXJQrAP7zeNuwvFQg,4 +isort-4.3.21.dist-info/LICENSE,sha256=BjKUABw9Uj26y6ud1UrCKZgnVsyvWSylMkCysM3YIGU,1089 +isort-4.3.21.dist-info/METADATA,sha256=8fY1DuLOn_UnCH58A8AcsCUZpYWeLCsQF-n-GIXlxOM,19749 +isort-4.3.21.dist-info/RECORD,, +isort-4.3.21.dist-info/WHEEL,sha256=h_aVn5OB2IERUjMbi2pucmR_zzWJtk303YXvhh60NJ8,110 +isort-4.3.21.dist-info/entry_points.txt,sha256=2M99eSFpnteDm3ekW8jya2a3A0-vFntKdT1fP93Tyks,148 +isort-4.3.21.dist-info/top_level.txt,sha256=mrBLoVpJnQWBbnMOSdzkjN1E9Z-e3Zd-MRlo88bstUk,6 +isort/__init__.py,sha256=_DTTMASePJCqsKnRJPf_YgFv5ZJOHg1uPLkrQHcqA2c,1380 +isort/__main__.py,sha256=9tThPqyOnY86bHaxJ0WciTd-rfKN3O-PQoNGBO2xhio,205 +isort/__pycache__/__init__.cpython-37.pyc,, +isort/__pycache__/__main__.cpython-37.pyc,, +isort/__pycache__/finders.cpython-37.pyc,, +isort/__pycache__/hooks.cpython-37.pyc,, +isort/__pycache__/isort.cpython-37.pyc,, +isort/__pycache__/main.cpython-37.pyc,, +isort/__pycache__/natural.cpython-37.pyc,, +isort/__pycache__/pie_slice.cpython-37.pyc,, +isort/__pycache__/pylama_isort.cpython-37.pyc,, +isort/__pycache__/settings.cpython-37.pyc,, +isort/__pycache__/utils.cpython-37.pyc,, +isort/finders.py,sha256=0w39ygCFuOv40OHixflrOv_Xna8K78usa5ySwS9GkWE,13185 +isort/hooks.py,sha256=GcyPMF7raq3B1z4ubbzIWoMiY5DePDni0Nct5U87uMQ,3230 +isort/isort.py,sha256=krLW0QgwnVjUD3hYTpQmWkMa5TDEZxx6AbX80vlVNoA,53910 +isort/main.py,sha256=rS7dAu_0T-8Jxi3sDWu00IOjt4j0r3vJi6bXZn6RnQg,21974 +isort/natural.py,sha256=hlcWsGKfIUC4Atjp5IIqDCmg1madY6ave9oNiTGjJ0Q,1794 +isort/pie_slice.py,sha256=hO6l1XocvGAd8XTR8526r-G7XIncUQB53_DHQ4AZEYI,5612 +isort/pylama_isort.py,sha256=wF6NOEVuibme0l-5pH9pCW1j4vGaFamuwll494TnzDI,785 +isort/settings.py,sha256=4_Jf-9GaBy9fi6UJctLqesIAMAegWekRIJdJmH5TBNE,17452 +isort/utils.py,sha256=KtazEoeX9XmtcrUGP6xl5lBX7Ye2N08ACGaWxiGcIaE,1344 diff --git a/Display/.venv/lib/python3.7/site-packages/isort-4.3.21.dist-info/WHEEL b/Display/.venv/lib/python3.7/site-packages/isort-4.3.21.dist-info/WHEEL new file mode 100644 index 0000000..78e6f69 --- /dev/null +++ b/Display/.venv/lib/python3.7/site-packages/isort-4.3.21.dist-info/WHEEL @@ -0,0 +1,6 @@ +Wheel-Version: 1.0 +Generator: bdist_wheel (0.33.4) +Root-Is-Purelib: true +Tag: py2-none-any +Tag: py3-none-any + diff --git a/Display/.venv/lib/python3.7/site-packages/isort-4.3.21.dist-info/entry_points.txt b/Display/.venv/lib/python3.7/site-packages/isort-4.3.21.dist-info/entry_points.txt new file mode 100644 index 0000000..3a77a18 --- /dev/null +++ b/Display/.venv/lib/python3.7/site-packages/isort-4.3.21.dist-info/entry_points.txt @@ -0,0 +1,9 @@ +[console_scripts] +isort = isort.main:main + +[distutils.commands] +isort = isort.main:ISortCommand + +[pylama.linter] +isort = isort.pylama_isort:Linter + diff --git a/Display/.venv/lib/python3.7/site-packages/isort-4.3.21.dist-info/top_level.txt b/Display/.venv/lib/python3.7/site-packages/isort-4.3.21.dist-info/top_level.txt new file mode 100644 index 0000000..2a79243 --- /dev/null +++ b/Display/.venv/lib/python3.7/site-packages/isort-4.3.21.dist-info/top_level.txt @@ -0,0 +1 @@ +isort diff --git a/Display/.venv/lib/python3.7/site-packages/isort/__init__.py b/Display/.venv/lib/python3.7/site-packages/isort/__init__.py new file mode 100644 index 0000000..9a0a073 --- /dev/null +++ b/Display/.venv/lib/python3.7/site-packages/isort/__init__.py @@ -0,0 +1,28 @@ +"""__init__.py. + +Defines the isort module to include the SortImports utility class as well as any defined settings. + +Copyright (C) 2013 Timothy Edmund Crosley + +Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated +documentation files (the "Software"), to deal in the Software without restriction, including without limitation +the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and +to permit persons to whom the Software is furnished to do so, subject to the following conditions: + +The above copyright notice and this permission notice shall be included in all copies or +substantial portions of the Software. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED +TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

It also provides some helper functions to make publishing one off messages to an MQTT server very straightforward. + +It supports Python 2.7.9+ or 3.4+, with limited support for Python 2.7 before 2.7.9. + +The MQTT protocol is a machine-to-machine (M2M)/"Internet of Things" connectivity protocol.

This means that +when client is restarted (not just reconnected, the object is recreated usually because the +program was restarted) the session is lost. This result in possible message lost. + +The following part of client session is lost: + +* QoS 2 messages which have been received from the Server, but have not been completely acknowledged. + + Since the client will blindly acknowledge any PUBCOMP (last message of a QoS 2 transaction), it + won't hang but will lost this QoS 2 message. + +* QoS 1 and QoS 2 messages which have been sent to the Server, but have not been completely acknowledged. + + This means that message passed to publish() may be lost. This could be mitigated by taking care + that all message passed to publish() has a corresponding on_publish() call. + + It also means that the broker may have the Qos2 message in the session. Since the client start + with an empty session it don't know it and will re-use the mid. This is not yet fixed. + +Also when clean_session is True, this library will republish QoS > 0 message accross network +reconnection. This means that QoS > 0 message won't be lost. But the standard say that +if we should discard any message for which the publish packet was sent. Our choice means that +we are not compliant with the standard and it's possible for QoS 2 to be received twice. +You should you clean_session = False if you need the QoS 2 guarantee of only one delivery. + +Usage and API +------------- + +Detailed API documentation is available through **pydoc**. Samples are available in the **examples** directory. + +The package provides two modules, a full client and a helper for simple publishing. + +Getting Started +*************** + +Here is a very simple example that subscribes to the broker $SYS topic tree and prints out the resulting messages: + +.. code:: python + + import paho.mqtt.client as mqtt + + # The callback for when the client receives a CONNACK response from the server. + def on_connect(client, userdata, flags, rc): + print("Connected with result code "+str(rc)) + + # Subscribing in on_connect() means that if we lose the connection and + # reconnect then subscriptions will be renewed. + client.subscribe("$SYS/#") + + # The callback for when a PUBLISH message is received from the server. + def on_message(client, userdata, msg): + print(msg.topic+" "+str(msg.payload)) + + client = mqtt.Client() + client.on_connect = on_connect + client.on_message = on_message + + client.connect("mqtt.eclipse.org", 1883, 60) + + # Blocking call that processes network traffic, dispatches callbacks and + # handles reconnecting. + # Other loop*() functions are available that give a threaded interface and a + # manual interface. + client.loop_forever() + +Client +****** + +You can use the client class as an instance, within a class or by subclassing. The general usage flow is as follows: + +* Create a client instance +* Connect to a broker using one of the ``connect*()`` functions +* Call one of the ``loop*()`` functions to maintain network traffic flow with the broker +* Use ``subscribe()`` to subscribe to a topic and receive messages +* Use ``publish()`` to publish messages to the broker +* Use ``disconnect()`` to disconnect from the broker + +Callbacks will be called to allow the application to process events as necessary. These callbacks are described below. + +Constructor / reinitialise +`````````````````````````` + +Client() +'''''''' + +.. code:: python + + Client(client_id="", clean_session=True, userdata=None, protocol=MQTTv311, transport="tcp") + +The ``Client()`` constructor takes the following arguments: + +client_id + the unique client id string used when connecting to the broker. If + ``client_id`` is zero length or ``None``, then one will be randomly + generated. In this case the ``clean_session`` parameter must be ``True``. + +clean_session + a boolean that determines the client type.

With pyparsing, you +don't need to learn a new syntax for defining grammars or matching expressions - the parsing module +provides a library of classes that you use to construct the grammar directly in Python. + +Here is a program to parse "Hello, World!" (or any greeting of the form +C{"<salutation>, <addressee>!"}), built up using L{Word}, L{Literal}, and L{And} elements +(L{'+'<ParserElement.__add__>} operator gives L{And} expressions, strings are auto-converted to +L{Literal} expressions):: + + from pyparsing import Word, alphas + + # define grammar of a greeting + greet = Word(alphas) + "," + Word(alphas) + "!" + + hello = "Hello, World!" + print (hello, "->", greet.parseString(hello)) + +The program outputs the following:: + + Hello, World! -> ['Hello', ',', 'World', '!'] + +The Python representation of the grammar is quite readable, owing to the self-explanatory +class names, and the use of '+', '|' and '^' operators. + +The L{ParseResults} object returned from L{ParserElement.parseString<ParserElement.parseString>} can be accessed as a nested list, a dictionary, or an +object with named attributes. + +The pyparsing module handles some of the problems that are typically vexing when writing text parsers: + - extra or missing whitespace (the above program will also handle "Hello,World!", "Hello , World !", etc.) + - quoted strings + - embedded comments + + +Getting Started - +----------------- +Visit the classes L{ParserElement} and L{ParseResults} to see the base classes that most other pyparsing +classes inherit from. Use the docstrings for examples of how to: + - construct literal match expressions from L{Literal} and L{CaselessLiteral} classes + - construct character word-group expressions using the L{Word} class + - see how to create repetitive expressions using L{ZeroOrMore} and L{OneOrMore} classes + - use L{'+'<And>}, L{'|'<MatchFirst>}, L{'^'<Or>}, and L{'&'<Each>} operators to combine simple expressions into more complex ones + - associate names with your parsed results using L{ParserElement.setResultsName} + - find some helpful expression short-cuts like L{delimitedList} and L{oneOf} + - find more useful common expressions in the L{pyparsing_common} namespace class +""" + +__version__ = "2.2.1" +__versionTime__ = "18 Sep 2018 00:49 UTC" +__author__ = "Paul McGuire <ptmcg@users.sourceforge.net>" + +import string +from weakref import ref as wkref +import copy +import sys +import warnings +import re +import sre_constants +import collections +import pprint +import traceback +import types +from datetime import datetime + +try: + from _thread import RLock +except ImportError: + from threading import RLock + +try: + # Python 3 + from collections.abc import Iterable + from collections.abc import MutableMapping +except ImportError: + # Python 2.7 + from collections import Iterable + from collections import MutableMapping + +try: + from collections import OrderedDict as _OrderedDict +except ImportError: + try: + from ordereddict import OrderedDict as _OrderedDict + except ImportError: + _OrderedDict = None + +#~ sys.stderr.write( "testing pyparsing module, version %s, %s\n" % (__version__,__versionTime__ ) ) + +__all__ = [ +'And', 'CaselessKeyword', 'CaselessLiteral', 'CharsNotIn', 'Combine', 'Dict', 'Each', 'Empty', +'FollowedBy', 'Forward', 'GoToColumn', 'Group', 'Keyword', 'LineEnd', 'LineStart', 'Literal', +'MatchFirst', 'NoMatch', 'NotAny', 'OneOrMore', 'OnlyOnce', 'Optional', 'Or', +'ParseBaseException', 'ParseElementEnhance', 'ParseException', 'ParseExpression', 'ParseFatalException', +'ParseResults', 'ParseSyntaxException', 'ParserElement', 'QuotedString', 'RecursiveGrammarException', +'Regex', 'SkipTo', 'StringEnd', 'StringStart', 'Suppress', 'Token', 'TokenConverter', +'White', 'Word', 'WordEnd', 'WordStart', 'ZeroOrMore', +'alphanums', 'alphas', 'alphas8bit', 'anyCloseTag', 'anyOpenTag', 'cStyleComment', 'col', +'commaSeparatedList', 'commonHTMLEntity', 'countedArray', 'cppStyleComment', 'dblQuotedString', +'dblSlashComment', 'delimitedList', 'dictOf', 'downcaseTokens', 'empty', 'hexnums', +'htmlComment', 'javaStyleComment', 'line', 'lineEnd', 'lineStart', 'lineno', +'makeHTMLTags', 'makeXMLTags', 'matchOnlyAtCol', 'matchPreviousExpr', 'matchPreviousLiteral', +'nestedExpr', 'nullDebugAction', 'nums', 'oneOf', 'opAssoc', 'operatorPrecedence', 'printables', +'punc8bit', 'pythonStyleComment', 'quotedString', 'removeQuotes', 'replaceHTMLEntity', +'replaceWith', 'restOfLine', 'sglQuotedString', 'srange', 'stringEnd', +'stringStart', 'traceParseAction', 'unicodeString', 'upcaseTokens', 'withAttribute', +'indentedBlock', 'originalTextFor', 'ungroup', 'infixNotation','locatedExpr', 'withClass', +'CloseMatch', 'tokenMap', 'pyparsing_common', +] + +system_version = tuple(sys.version_info)[:3] +PY_3 = system_version[0] == 3 +if PY_3: + _MAX_INT = sys.maxsize + basestring = str + unichr = chr + _ustr = str + + # build list of single arg builtins, that can be used as parse actions + singleArgBuiltins = [sum, len, sorted, reversed, list, tuple, set, any, all, min, max] + +else: + _MAX_INT = sys.maxint + range = xrange + + def _ustr(obj): + """Drop-in replacement for str(obj) that tries to be Unicode friendly.

You can look at the +method of importing numpy and pg.surfarray.

Learning to use numpy for images like this takes a +bit of learning, but the payoff is extremely fast image +manipulation in python. + +For Pygame 1.9.2 and up, this example also showcases a new feature +of surfarray.blit_surface: array broadcasting. If a source array +has either a width or height of 1, the array is repeatedly blitted +to the surface along that dimension to fill the surface. In fact, +a (1, 1) or (1, 1, 3) array results in a simple surface color fill. + +Just so you know how this breaks down. For each sampling of +time, 30% goes to each creating the gradient and blitting the +array.

There +are the main Sprite class and several Group classes that contain Sprites. +The use of these classes is entirely optional when using Pygame. The classes +are fairly lightweight and only provide a starting place for the code +that is common to most games. + +The Sprite class is intended to be used as a base class for the different +types of objects in the game. There is also a base Group class that simply +stores sprites. A game could create new types of Group classes that operate +on specially customized Sprite instances they contain. + +The basic Sprite class can draw the Sprites it contains to a Surface. The +Group.draw() method requires that each Sprite have a Surface.image attribute +and a Surface.rect. The Group.clear() method requires these same attributes +and can be used to erase all the Sprites with background. There are also +more advanced Groups: pygame.sprite.RenderUpdates() and +pygame.sprite.OrderedUpdates(). + +Lastly, this module contains several collision functions. These help find +sprites inside multiple groups that have intersecting bounding rectangles. +To find the collisions, the Sprites are required to have a Surface.rect +attribute assigned. + +The groups are designed for high efficiency in removing and adding Sprites +to them. They also allow cheap testing to see if a Sprite already exists in +a Group. A given Sprite can exist in any number of groups. A game could use +some groups to control object rendering, and a completely separate set of +groups to control interaction or player movement. Instead of adding type +attributes or bools to a derived Sprite class, consider keeping the +Sprites inside organized Groups. This will allow for easier lookup later +in the game. + +Sprites and Groups manage their relationships with the add() and remove() +methods. These methods can accept a single or multiple group arguments for +membership. The default initializers for these classes also take a +single group or list of groups as arguments for initial membership. It is safe +to repeatedly add and remove the same Sprite from a Group. + +While it is possible to design sprite and group classes that don't derive +from the Sprite and AbstractGroup classes below, it is strongly recommended +that you extend those when you create a new Sprite or Group class. + +Sprites are not thread safe, so lock them yourself if using threads. + +""" + +##todo +## a group that holds only the 'n' most recent elements. +## sort of like the GroupSingle class, but holding more +## than one sprite +## +## drawing groups that can 'automatically' store the area +## underneath so they can "clear" without needing a background +## function. obviously a little slower than normal, but nice +## to use in many situations.

This +module will only be functional when pygame can use the external Numpy or +Numeric packages. + +Every pixel is stored as a single integer value to represent the red, +green, and blue colors. The 8bit images use a value that looks into a +colormap. Pixels with higher depth use a bit packing process to place +three or four values into a single number. + +The arrays are indexed by the X axis first, followed by the Y +axis. Arrays that treat the pixels as a single integer are referred to +as 2D arrays. This module can also separate the red, green, and blue +color values into separate indices. These types of arrays are referred +to as 3D arrays, and the last index is 0 for red, 1 for green, and 2 for +blue. + +Supported array types are + + numpy + numeric (deprecated; will be removed in Pygame 1.9.3.) + +The default will be numpy, if installed. Otherwise, Numeric will be set +as default if installed, and a deprecation warning will be issued. If +neither numpy nor Numeric are installed, the module will raise an +ImportError. + +The array type to use can be changed at runtime using the use_arraytype() +method, which requires one of the above types as string. + +Note: numpy and Numeric are not completely compatible. Certain array +manipulations, which work for one type, might behave differently or even +completely break for the other. + +Additionally, in contrast to Numeric, numpy does use unsigned 16-bit +integers. Images with 16-bit data will be treated as unsigned +integers. Numeric instead uses signed integers for the representation, +which is important to keep in mind, if you use the module's functions +and wonder about the values. +""" + +# Try to import the necessary modules. +# import pygame._numpysurfarray as numpysf +numpysf = None + + +from pygame.pixelcopy import array_to_surface, make_surface as pc_make_surface + +__all__ = ["array_to_surface", "pc_make_surface"] + +def blit_array (surface, array): + """pygame.surfarray.blit_array(Surface, array): return None + + Blit directly from a array values. + + Directly copy values from an array into a Surface.

It reads +and writes PNG files with all allowable bit depths (1/2/4/8/16/24/32/48/64 +bits per pixel) and colour combinations: greyscale (1/2/4/8/16 bit); RGB, +RGBA, LA (greyscale with alpha) with 8/16 bits per channel; colour mapped +images (1/2/4/8 bit). Adam7 interlacing is supported for reading and +writing. A number of optional chunks can be specified (when writing) +and understood (when reading): ``tRNS``, ``bKGD``, ``gAMA``. + +For help, type ``import png; help(png)`` in your python interpreter. + +A good place to start is the :class:`Reader` and :class:`Writer` classes. + +This file can also be used as a command-line utility to convert +`Netpbm `_ PNM files to PNG, and the reverse conversion from PNG to +PNM. The interface is similar to that of the ``pnmtopng`` program from +Netpbm. Type ``python png.py --help`` at the shell prompt +for usage and a list of options. + +A note on spelling and terminology +---------------------------------- + +Generally British English spelling is used in the documentation. So +that's "greyscale" and "colour". This not only matches the author's +native language, it's also used by the PNG specification. + +The major colour models supported by PNG (and hence by PyPNG) are: +greyscale, RGB, greyscale--alpha, RGB--alpha. These are sometimes +referred to using the abbreviations: L, RGB, LA, RGBA. In this case +each letter abbreviates a single channel: *L* is for Luminance or Luma or +Lightness which is the channel used in greyscale images; *R*, *G*, *B* stand +for Red, Green, Blue, the components of a colour image; *A* stands for +Alpha, the opacity channel (used for transparency effects, but higher +values are more opaque, so it makes sense to call it opacity). + +A note on formats +----------------- + +When getting pixel data out of this module (reading) and presenting +data to this module (writing) there are a number of ways the data could +be represented as a Python value. Generally this module uses one of +three formats called "flat row flat pixel", "boxed row flat pixel", and +"boxed row boxed pixel". Basically the concern is whether each pixel +and each row comes in its own little tuple (box), or not. + +Consider an image that is 3 pixels wide by 2 pixels high, and each pixel +has RGB components: + +Boxed row flat pixel:: + + list([R,G,B, R,G,B, R,G,B], + [R,G,B, R,G,B, R,G,B]) + +Each row appears as its own list, but the pixels are flattened so that +three values for one pixel simply follow the three values for the previous +pixel. This is the most common format used, because it provides a good +compromise between space and convenience. PyPNG regards itself as +at liberty to replace any sequence type with any sufficiently compatible +other sequence type; in practice each row is an array (from the array +module), and the outer list is sometimes an iterator rather than an +explicit list (so that streaming is possible). + +Flat row flat pixel:: + + [R,G,B, R,G,B, R,G,B, + R,G,B, R,G,B, R,G,B] + +The entire image is one single giant sequence of colour values. +Generally an array will be used (to save space), not a list. + +Boxed row boxed pixel:: + + list([ (R,G,B), (R,G,B), (R,G,B) ], + [ (R,G,B), (R,G,B), (R,G,B) ]) + +Each row appears in its own list, but each pixel also appears in its own +tuple. A serious memory burn in Python. + +In all cases the top row comes first, and for each row the pixels are +ordered from left-to-right. Within a pixel the values appear in the +order, R-G-B-A (or L-A for greyscale--alpha). + +There is a fourth format, mentioned because it is used internally, +is close to what lies inside a PNG file itself, and has some support +from the public API. This format is called packed. When packed, +each row is a sequence of bytes (integers from 0 to 255), just as +it is before PNG scanline filtering is applied. When the bit depth +is 8 this is essentially the same as boxed row flat pixel; when the +bit depth is less than 8, several pixels are packed into each byte; +when the bit depth is 16 (the only value more than 8 that is supported +by the PNG image format) each pixel value is decomposed into 2 bytes +(and `packed` is a misnomer). This format is used by the +:meth:`Writer.write_packed` method. It isn't usually a convenient +format, but may be just right if the source data for the PNG image +comes from something that uses a similar format (for example, 1-bit +BMPs, or another PNG file). + +And now, my famous members +-------------------------- +""" + +__version__ = "$URL: http://pypng.googlecode.com/svn/trunk/code/png.py $ $Rev: 228 $" + +from pygame.compat import geterror, imap_ +from array import array +from pygame.tests.test_utils import tostring +import itertools +import math +import operator +import struct +import sys +import zlib +import warnings + +__all__ = ["Image", "Reader", "Writer", "write_chunks", "from_array"] + + +# The PNG signature. +# http://www.w3.org/TR/PNG/#5PNG-file-signature +_signature = struct.pack("8B", 137, 80, 78, 71, 13, 10, 26, 10) + +_adam7 = ( + (0, 0, 8, 8), + (4, 0, 8, 8), + (0, 4, 4, 8), + (2, 0, 4, 4), + (0, 2, 2, 4), + (1, 0, 2, 2), + (0, 1, 1, 2), +) + + +def group(s, n): + # See + # http://www.python.org/doc/2.6/library/functions.html#zip + return zip(*[iter(s)] * n) + + +def isarray(x): + """Same as ``isinstance(x, array)``. + """ + return isinstance(x, array) + + +# Conditionally convert to bytes.

Briefly: + "small" bit depths (1,2,4) are only allowed with greyscale and + colour mapped images; colour mapped images cannot have bit depth + 16. + + For colour mapped images (in other words, when the `palette` + argument is specified) the `bitdepth` argument must match one of + the valid PNG bit depths: 1, 2, 4, or 8. (It is valid to have a + PNG image with a palette and an ``sBIT`` chunk, but the meaning + is slightly different; it would be awkward to press the + `bitdepth` argument into service for this.) + + The `palette` option, when specified, causes a colour mapped image + to be created: the PNG colour type is set to 3; greyscale + must not be set; alpha must not be set; transparent must + not be set; the bit depth must be 1,2,4, or 8. When a colour + mapped image is created, the pixel values are palette indexes + and the `bitdepth` argument specifies the size of these indexes + (not the size of the colour values in the palette). + + The palette argument value should be a sequence of 3- or + 4-tuples. 3-tuples specify RGB palette entries; 4-tuples + specify RGBA palette entries. If both 4-tuples and 3-tuples + appear in the sequence then all the 4-tuples must come + before all the 3-tuples. A ``PLTE`` chunk is created; if there + are 4-tuples then a ``tRNS`` chunk is created as well. The + ``PLTE`` chunk will contain all the RGB triples in the same + sequence; the ``tRNS`` chunk will contain the alpha channel for + all the 4-tuples, in the same sequence. Palette entries + are always 8-bit. + + If specified, the `transparent` and `background` parameters must + be a tuple with three integer values for red, green, blue, or + a simple integer (or singleton tuple) for a greyscale image. + + If specified, the `gamma` parameter must be a positive number + (generally, a float). A ``gAMA`` chunk will be created. Note that + this will not change the values of the pixels as they appear in + the PNG file, they are assumed to have already been converted + appropriately for the gamma specified. + + The `compression` argument specifies the compression level + to be used by the ``zlib`` module. Higher values are likely + to compress better, but will be slower to compress. The + default for this argument is ``None``; this does not mean + no compression, rather it means that the default from the + ``zlib`` module is used (which is generally acceptable). + + If `interlace` is true then an interlaced image is created + (using PNG's so far only interlace method, *Adam7*). This does not + affect how the pixels should be presented to the encoder, rather + it changes how they are arranged into the PNG file. On slow + connexions interlaced images can be partially decoded by the + browser to give a rough view of the image that is successively + refined as more image data appears. + + .. note :: + + Enabling the `interlace` option requires the entire image + to be processed in working memory. + + `chunk_limit` is used to limit the amount of memory used whilst + compressing the image.

It doesn't actually work. Please bear with us. Meanwhile + enjoy the complimentary snacks (on request) and please use a + 2-dimensional array. + + Unless they are specified using the *info* parameter, the PNG's + height and width are taken from the array size. For a 3 dimensional + array the first axis is the height; the second axis is the width; + and the third axis is the channel number. Thus an RGB image that is + 16 pixels high and 8 wide will use an array that is 16x8x3. For 2 + dimensional arrays the first axis is the height, but the second axis + is ``width*channels``, so an RGB image that is 16 pixels high and 8 + wide will use a 2-dimensional array that is 16x24 (each row will be + 8*3==24 sample values). + + *mode* is a string that specifies the image colour format in a + PIL-style mode. It can be: + + ``'L'`` + greyscale (1 channel) + ``'LA'`` + greyscale with alpha (2 channel) + ``'RGB'`` + colour image (3 channel) + ``'RGBA'`` + colour image with alpha (4 channel) + + The mode string can also specify the bit depth (overriding how this + function normally derives the bit depth, see below). Appending + ``';16'`` to the mode will cause the PNG to be 16 bits per channel; + any decimal from 1 to 16 can be used to specify the bit depth. + + When a 2-dimensional array is used *mode* determines how many + channels the image has, and so allows the width to be derived from + the second array dimension. + + The array is expected to be a ``numpy`` array, but it can be any + suitable Python sequence. For example, a list of lists can be used: + ``png.from_array([[0, 255, 0], [255, 0, 255]], 'L')``. The exact + rules are: ``len(a)`` gives the first dimension, height; + ``len(a[0])`` gives the second dimension; ``len(a[0][0])`` gives the + third dimension, unless an exception is raised in which case a + 2-dimensional array is assumed. It's slightly more complicated than + that because an iterator of rows can be used, and it all still + works.

A 1 byte datatype will give a bit depth of + 8, a 2 byte datatype will give a bit depth of 16. If the datatype + does not have an implicit size, for example it is a plain Python + list of lists, as above, then a default of 8 is used. + + The *info* parameter is a dictionary that can be used to specify + metadata (in the same style as the arguments to the + :class:``png.Writer`` class). For this function the keys that are + useful are: + + height + overrides the height derived from the array dimensions and allows + *a* to be an iterable. + width + overrides the width derived from the array dimensions. + bitdepth + overrides the bit depth derived from the element datatype (but + must match *mode* if that also specifies a bit depth). + + Generally anything specified in the + *info* dictionary will override any implicit choices that this + function would otherwise make, but must match any explicit ones. + For example, if the *info* dictionary has a ``greyscale`` key then + this must be true when mode is ``'L'`` or ``'LA'`` and false when + mode is ``'RGB'`` or ``'RGBA'``. + """ + + # We abuse the *info* parameter by modifying it.

By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) 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 +this service 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 make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. 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. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute 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 and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +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 +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the 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 a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, 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. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE 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. + + 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 +convey 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 2 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, write to the Free Software + Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA + + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author + Gnomovision 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, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary. Here is a sample; alter the names: + + Yoyodyne, Inc., hereby disclaims all copyright interest in the program + `Gnomovision' (which makes passes at compilers) written by James Hacker. + + , 1 April 1989 + Ty Coon, President of Vice + +This 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 Library General +Public License instead of this License. diff --git a/Display/.venv/lib/python3.7/site-packages/pylint-2.5.3.dist-info/INSTALLER b/Display/.venv/lib/python3.7/site-packages/pylint-2.5.3.dist-info/INSTALLER new file mode 100644 index 0000000..a1b589e --- /dev/null +++ b/Display/.venv/lib/python3.7/site-packages/pylint-2.5.3.dist-info/INSTALLER @@ -0,0 +1 @@ +pip diff --git a/Display/.venv/lib/python3.7/site-packages/pylint-2.5.3.dist-info/METADATA b/Display/.venv/lib/python3.7/site-packages/pylint-2.5.3.dist-info/METADATA new file mode 100644 index 0000000..5e19131 --- /dev/null +++ b/Display/.venv/lib/python3.7/site-packages/pylint-2.5.3.dist-info/METADATA @@ -0,0 +1,204 @@ +Metadata-Version: 2.1 +Name: pylint +Version: 2.5.3 +Summary: python code static checker +Home-page: https://github.com/PyCQA/pylint +Author: Python Code Quality Authority +Author-email: code-quality@python.org +License: GPL +Platform: UNKNOWN +Classifier: Development Status :: 6 - Mature +Classifier: Environment :: Console +Classifier: Intended Audience :: Developers +Classifier: License :: OSI Approved :: GNU General Public License (GPL) +Classifier: Operating System :: OS Independent +Classifier: Programming Language :: Python +Classifier: Programming Language :: Python :: 3 +Classifier: Programming Language :: Python :: 3.5 +Classifier: Programming Language :: Python :: 3.6 +Classifier: Programming Language :: Python :: 3.7 +Classifier: Programming Language :: Python :: 3.8 +Classifier: Programming Language :: Python :: 3 :: Only +Classifier: Programming Language :: Python :: Implementation :: CPython +Classifier: Programming Language :: Python :: Implementation :: PyPy +Classifier: Topic :: Software Development :: Debuggers +Classifier: Topic :: Software Development :: Quality Assurance +Classifier: Topic :: Software Development :: Testing +Requires-Python: >=3.5.* +Requires-Dist: astroid (<=2.5,>=2.4.0) +Requires-Dist: isort (<5,>=4.2.5) +Requires-Dist: mccabe (<0.7,>=0.6) +Requires-Dist: toml (>=0.7.1) +Requires-Dist: colorama ; sys_platform=="win32" + + +README for Pylint - http://pylint.pycqa.org/ +============================================ + +.. image:: https://travis-ci.org/PyCQA/pylint.svg?branch=master + :target: https://travis-ci.org/PyCQA/pylint + +.. image:: https://ci.appveyor.com/api/projects/status/rbvwhakyj1y09atb/branch/master?svg=true + :alt: AppVeyor Build Status + :target: https://ci.appveyor.com/project/PCManticore/pylint + +.. image:: https://coveralls.io/repos/github/PyCQA/pylint/badge.svg?branch=master + :target: https://coveralls.io/github/PyCQA/pylint?branch=master + + +.. image:: https://img.shields.io/pypi/v/pylint.svg + :alt: Pypi Package version + :target: https://pypi.python.org/pypi/pylint + +.. image:: https://readthedocs.org/projects/pylint/badge/?version=latest + :target: http://pylint.readthedocs.io/en/latest/?badge=latest + :alt: Documentation Status + +.. image:: https://img.shields.io/badge/code%20style-black-000000.svg + :target: https://github.com/ambv/black + +.. |tideliftlogo| image:: doc/media/Tidelift_Logos_RGB_Tidelift_Shorthand_On-White_small.png + :width: 75 + :height: 60 + :alt: Tidelift + +.. list-table:: + :widths: 10 100 + + * - |tideliftlogo| + - Professional support for pylint is available as part of the `Tidelift + Subscription`_.
