It is + numbered 2 because it goes with version 2 of the ordinary GPL.] + + 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 Library General Public License, applies to some +specially designated Free Software Foundation software, and to any +other libraries whose authors decide to use it. You can use it for +your libraries, 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 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 a program 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. + + Our method of protecting your rights has two steps: (1) copyright +the library, and (2) offer you this license which gives you legal +permission to copy, distribute and/or modify the library. + + Also, for each distributor's protection, we want to make certain +that everyone understands that there is no warranty for this free +library. If the library is modified by someone else and passed on, we +want its recipients to know that what they have is not the original +version, 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 companies distributing free +software will individually obtain patent licenses, thus in effect +transforming the program into proprietary software. To prevent this, +we have made it clear that any patent must be licensed for everyone's +free use or not licensed at all. + + Most GNU software, including some libraries, is covered by the ordinary +GNU General Public License, which was designed for utility programs. This +license, the GNU Library General Public License, applies to certain +designated libraries. This license is quite different from the ordinary +one; be sure to read it in full, and don't assume that anything in it is +the same as in the ordinary license. + + The reason we have a separate public license for some libraries is that +they blur the distinction we usually make between modifying or adding to a +program and simply using it. Linking a program with a library, without +changing the library, is in some sense simply using the library, and is +analogous to running a utility program or application program. However, in +a textual and legal sense, the linked executable is a combined work, a +derivative of the original library, and the ordinary General Public License +treats it as such. + + Because of this blurred distinction, using the ordinary General +Public License for libraries did not effectively promote software +sharing, because most developers did not use the libraries. We +concluded that weaker conditions might promote sharing better. + + However, unrestricted linking of non-free programs would deprive the +users of those programs of all benefit from the free status of the +libraries themselves. This Library General Public License is intended to +permit developers of non-free programs to use free libraries, while +preserving your freedom as a user of such programs to change the free +libraries that are incorporated in them. (We have not seen how to achieve +this as regards changes in header files, but we have achieved it as regards +changes in the actual functions of the Library.) The hope is that this +will lead to faster development of free libraries. + + 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, while the latter only +works together with the library. + + Note that it is possible for a library to be covered by the ordinary +General Public License rather than by this special one. + + GNU LIBRARY GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library which +contains a notice placed by the copyright holder or other authorized +party saying it may be distributed under the terms of this Library +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 compile 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) 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. + + c) 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. + + d) 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 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. + + 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 to +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 Library 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. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO +WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. +EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR +OTHER PARTIES PROVIDE THE LIBRARY "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 +LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME +THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. 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 LIBRARY 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 +LIBRARY (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 LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), 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 Libraries + + If you develop a new library, and you want it to be of the greatest +possible use to the public, we recommend making it free software that +everyone can redistribute and change. You can do so by permitting +redistribution under these terms (or, alternatively, under the terms of the +ordinary General Public License). + + To apply these terms, attach the following notices to the library. 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 library is free software; you can redistribute it and/or + modify it under the terms of the GNU Library General Public + License as published by the Free Software Foundation; either + version 2 of the License, or (at your option) any later version. + + This library 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 + Library General Public License for more details. + + You should have received a copy of the GNU Library General Public + License along with this library; if not, write to the + Free Software Foundation, Inc., 59 Temple Place - Suite 330, + Boston, MA 02111-1307 USA. + +Also add information on how to contact you by electronic and paper mail. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the library, if +necessary.

The only exception known to me + is Firefox that adjusts glyph widths to do justification. Most other + uses that do not write to the returned structs (or structs accessible from + them) should be ported to the new readonly API to benefit from major + optimizations (in this case, line extents caching). The list includes, + but is not limited to, Gtk+, SWT, ClassPath, gnome-applets, libgnomeprint, + xmlroff, GtkMathView, Conglomerate, Dia, Anjuta, wxWindows, The Gimp, + and various other applications/libraries: + + http://www.google.com/codesearch?hl=en&q=+pango_layout_(iter_)%3Fget_(lines%3F%7Crun)%5B%5E_%5D&start=50&sa=N + + Worth noting here is that, many uses of pango_layout_get_lines() can be + replaced by a pango_layout_get_iter() that works both more elegantly and + more efficiently. The versioning macros introduced in this release can be + used to make code use these new symbols without breaking compilation + against older Pango (though, such code compiled with the new Pango cannot + be run against an older Pango). + + - pango_language_get_default(): Note that, this does not make Pango + fallback to the default language automatically (yet), but the user can + use this function to set the default language of the locale on a context: + + pango_context_set_language (context, pango_language_get_default()); + + This essentially deprecates gtk_get_default_language().

Avoids one pango_font_get_glyph_extents() + call per glyph per layout rendering. We now make 2 such calls. + - Don't cache run_logical_rect in PangoLayoutIter. + Avoids one pango_font_get_glyph_extents() call per glyph per layout + rendering. We are down to 1 now. + - Cache line extents. This avoids the final pango_font_get_glyph_extents() + call per glyph per layout rendering. Now we don't make any + pango_font_get_glyph_extents() calls when rendering a layout (some + conditions apply)! + - Replace PANGO_IS_RENDERER with PANGO_IS_RENDERER_FAST for most + internal uses, that is, just a NULL-check. + - Use simple, fast, casts instead of PANGO_CAIRO_*() macros where the + object cannot have reached us if it wasn't of the right type. + +* Bugs fixed in this release: + Bug 135683 – Cache glyphstring extents + Red Hat Bug 211964: [ta] Rendering issue with Tamil + Patch from LingNing Zhang + Red Hat Bug 213632: ZWJ (200d) and ZWNJ (200c) showing same output + Patch from LingNing Zhang + Bug 371388 – Add Thai langauage engine + Patch from Theppitak Karoonboonyanan + Bug 377975 – bug in _pango_glyph_item_iter_next_cluster + Bug 369670 – Checked g_free calls + +Changes that also appeared between 1.14.7 and 1.14.8 +===================================================== +* Improved thread-safety.

Pango can be used anywhere that text layout +is needed; however, most of the work on Pango so far has been done using +the GTK widget toolkit as a test platform. Pango forms the core of text +and font handling for GTK. + +Pango is designed to be modular; the core Pango layout can be used +with different font backends.

It has the +advantage that the same code can be used for display and printing. + +We suggest using Pango with Cairo as described above, but you can also +do X-specific rendering using the Xft library. The Xft backend uses +version 2 of the Xft library to manage client side fonts. Version 2 of +Xft is available from https://xlibs.freedesktop.org/release/. You'll +need the libXft package, and possibly the libXrender and renderext +packages as well.

Their +pkg-config files are needed on all builds unless marked with a *, where +only their headers/import libraries are needed on Visual Studio: + +-GLib +-Fribidi +-Cairo* (With Win32 support built in, and optionally FreeType and FontConfig + support for building PangoFT2.) +-FreeType* (Optional, needed for PangoFT2) +-FontConfig* (Optional, needed for PangoFT2) +-HarfBuzz* (Optional, GLib and FreeType support required if used, needed for PangoFT2) + +Please see meson.build to see what versions are needed for these dependencies. + +Follow the following steps to build Pango: + +1) Invoke the Meson configuration as follows, in a directory separate from the sources: + +(With MinGW, please adjust the paths accordingly, in a MSYS/MSYS2 bash prompt) +PATH=/devel/dist/glib-2.8.0/bin:$PATH ACLOCAL_FLAGS="-I /devel/dist/glib-2.8.0/share/aclocal" PKG_CONFIG_PATH=/devel/dist/glib-2.8.0/lib/pkgconfig:$PKG_CONFIG_PATH CC='gcc -mtune=pentium3' CPPFLAGS='-I/opt/gnu/include' LDFLAGS='-L/opt/gnu/lib' CFLAGS=-O meson $(PATH_TO_SRC) --buildtype=$(buildtype) --prefix=$(PREFIX) + +(With Visual Studio, set the INCLUDE, LIB, PATH and PKG_CONFIG_PATH envvars as +needed before running the following in a Visual Studio command prompt) +python $(PATH_TO_meson.py) $(PATH_TO_SRC) --buildtype=$(buildtype) --prefix=$(PREFIX) + +For Visual Studio builds, building using the Visual Studio IDE is also supported +with Visual Studio 2010, 2015 and 2017. Append --backend=vs to the Meson +configuration command above to use this support. + +2) Build Pango by running Ninja, or by opening and building the generated + Visual Studio 2010/2015/2017 solution file. + +3) Run tests and/or install the build using the "test" and "install" targets + or sub-projects respectively. + +4) If building with Visual Studio 2008, you will need to do the run the following + lines in the Visual Studio or SDK command prompt after building and installing. + From the build directory: + for /f %a in (*.dll.manifest) do if exist $(PREFIX)\bin\%~na /manifest %a /outputresource:$(PREFIX)\bin\%~na;2 + for /f %a in (*.exe.manifest) do if exist $(PREFIX)\bin\%~na /manifest %a /outputresource:$(PREFIX)\bin\%~na;1 + for /f %a in (*.exe.manifest) do if exist $(PREFIX)\libexec\installed-tests\pango\%~na /manifest %a /outputresource:$(PREFIX)\libexec\installed-tests\pango\%~na;1 + + So that the security manifests that are generated can be embedded into the built + DLLs and EXEs so that they can be usable. + +See the following GNOME Live! page for a more detailed description of building +Pango's dependencies with Visual Studio: +

With the base Pango interfaces, you could create a +PangoAttrList and apply it to the +text; the problem is that you'd need to apply attributes to some +numeric range of characters, for example "characters 12-17." This is +broken from an internationalization standpoint; once the text is +translated, the word you wanted to italicize could be in a different +position. + + + +The solution is to include the text attributes in the string to be +translated. Pango provides this feature with a small markup language. +You can parse a marked-up string into the string text plus a +PangoAttrList using either of +pango_parse_markup() or +pango_markup_parser_new(). + + + +A simple example of a marked-up string might be: +"<span foreground="blue" size="x-large">Blue text</span> is <i>cool</i>!" + + + +Pango uses #GMarkup to parse this language, which means that XML features +such as numeric character entities such as &#169; for © can +be used too. + + + +The root tag of a marked-up document is <markup>, but pango_parse_markup() allows you to +omit this tag, so you will most likely never need to use it. The most +general markup tag is <span>, then there are some convenience +tags. <span> has the following attributes: +<span> attributes + + +fontSince 1.21 +font_desc + +A font description string, such as "Sans Italic 12". See +pango_font_description_from_string() +for a description of the format of the string representation . Note that any +other span attributes will override this description.

Pango will make sure that + * Asian languages take the right form, while other scripts are rotated normally. + * + * The correct way to set gravity on a layout is to set it on the context + * associated with it using pango_context_set_base_gravity(). The context + * of a layout can be accessed using pango_layout_get_context(). The currently + * set base gravity of the context can be accessed using + * pango_context_get_base_gravity() and the resolved + * gravity of it using pango_context_get_gravity(). The resolved gravity is + * the same as the base gravity for the most part, except that if the base + * gravity is set to %PANGO_GRAVITY_AUTO, the resolved gravity will depend + * on the current matrix set on context, and is derived using + * pango_gravity_get_for_matrix(). + * + * The next thing an application may want to set on the context is the + * gravity hint. A #PangoGravityHint instructs how + * different scripts should react to the set base gravity. + * + * Font descriptions have a gravity property too, that can be set using + * pango_font_description_set_gravity() and accessed using + * pango_font_description_get_gravity(). However, those are rarely useful + * from application code and are mainly used by #PangoLayout internally. + * + * Last but not least, one can create #PangoAttributes for gravity + * and gravity hint using pango_attr_gravity_new() and + * pango_attr_gravity_hint_new(). + */ +#include "config.h" + +#include "pango-gravity.h" + +#include + +/** + * pango_gravity_to_rotation: + * @gravity: gravity to query + * + * Converts a #PangoGravity value to its natural rotation in radians. + * @gravity should not be %PANGO_GRAVITY_AUTO. + * + * Note that pango_matrix_rotate() takes angle in degrees, not radians. + * So, to call pango_matrix_rotate() with the output of this function + * you should multiply it by (180. / G_PI). + * + * Return value: the rotation value corresponding to @gravity. + * + * Since: 1.16 + */ +double +pango_gravity_to_rotation (PangoGravity gravity) +{ + double rotation; + + g_return_val_if_fail (gravity != PANGO_GRAVITY_AUTO, 0); + + switch (gravity) + { + default: + case PANGO_GRAVITY_AUTO: /* shut gcc up */ + case PANGO_GRAVITY_SOUTH: rotation = 0; break; + case PANGO_GRAVITY_NORTH: rotation = G_PI; break; + case PANGO_GRAVITY_EAST: rotation = -G_PI_2; break; + case PANGO_GRAVITY_WEST: rotation = +G_PI_2; break; + } + + return rotation; +} + +/** + * pango_gravity_get_for_matrix: + * @matrix: (nullable): a #PangoMatrix + * + * Finds the gravity that best matches the rotation component + * in a #PangoMatrix. + * + * Return value: the gravity of @matrix, which will never be + * %PANGO_GRAVITY_AUTO, or %PANGO_GRAVITY_SOUTH if @matrix is %NULL + * + * Since: 1.16 + */ +PangoGravity +pango_gravity_get_for_matrix (const PangoMatrix *matrix) +{ + PangoGravity gravity; + double x; + double y; + + if (!matrix) + return PANGO_GRAVITY_SOUTH; + + x = matrix->xy; + y = matrix->yy; + + if (fabs (x) > fabs (y)) + gravity = x > 0 ?

With the base Pango interfaces, you could create a + * #PangoAttrList and apply it to the text; the problem is that you'd + * need to apply attributes to some numeric range of characters, for + * example "characters 12-17." This is broken from an internationalization + * standpoint; once the text is translated, the word you wanted to + * italicize could be in a different position. + * + * The solution is to include the text attributes in the string to be + * translated. Pango provides this feature with a small markup language. + * You can parse a marked-up string into the string text plus a + * #PangoAttrList using either of pango_parse_markup() or + * pango_markup_parser_new(). + * + * A simple example of a marked-up string might be: + * |[ + * Blue text is cool! + * ]| + * + * Pango uses #GMarkup to parse this language, which means that XML + * features such as numeric character entities such as &#169; for + * © can be used too. + * + * The root tag of a marked-up document is <markup>, but + * pango_parse_markup()allows you to omit this tag, so you will most + * likely never need to use it. The most general markup tag is <span>, + * then there are some convenience tags. + * + * <span> has the following attributes: + * + * font_desc + * : A font description string, such as "Sans Italic 12". + * See pango_font_description_from_string() for a description of the + * format of the string representation . Note that any other span + * attributes will override this description. So if you have "Sans Italic" + * and also a style="normal" attribute, you will get Sans normal, + * not italic. + * + * font_family + * : A font family name + * + * font_size, size + * : Font size in 1024ths of a point, or one of the absolute + * sizes 'xx-small', 'x-small', 'small', 'medium', 'large', + * 'x-large', 'xx-large', or one of the relative sizes 'smaller' + * or 'larger'. If you want to specify a absolute size, it's usually + * easier to take advantage of the ability to specify a partial + * font description using 'font'; you can use |font='12.5'| + * rather than |size='12800'|. + * + * font_style + * : One of 'normal', 'oblique', 'italic' + * + * font_weight + * : One of 'ultralight', 'light', 'normal', 'bold', + * 'ultrabold', 'heavy', or a numeric weight + * + * font_variant + * : One of 'normal' or 'smallcaps' + * + * font_stretch, stretch + * : One of 'ultracondensed', 'extracondensed', 'condensed', + * 'semicondensed', 'normal', 'semiexpanded', 'expanded', + * 'extraexpanded', 'ultraexpanded' + * + * font_features + * : A comma separated list of OpenType font feature + * settings, in the same syntax as accepted by CSS. E.g: + * |font_features='dlig=1, -kern, afrc on'| + * + * foreground, fgcolor + * : An RGB color specification such as '#00FF00' or a color + * name such as 'red'. Since 1.38, an RGBA color specification such + * as '#00FF007F' will be interpreted as specifying both a foreground + * color and foreground alpha. + * + * background, bgcolor + * : An RGB color specification such as '#00FF00' or a color + * name such as'red'. + * Since 1.38, an RGBA color specification such as '#00FF007F' will + * be interpreted as specifying both a background color and + * background alpha. + * + * alpha, fgalpha + * : An alpha value for the foreground color, either a plain + * integer between 1 and 65536 or a percentage value like '50%'. + * + * background_alpha, bgalpha + * : An alpha value for the background color, either a plain + * integer between 1 and 65536 or a percentage value like '50%'. + * + * underline + * : One of 'none', 'single', 'double', 'low', 'error' + * + * underline_color + * : The color of underlines; an RGB color + * specification such as '#00FF00' or a color name such as 'red' + * + * rise + * : Vertical displacement, in Pango units. Can be negative for + * subscript, positive for superscript. + * + * strikethrough + * : 'true' or 'false' whether to strike through the text + * + * strikethrough_color + * : The color of strikethrough lines; an RGB + * color specification such as '#00FF00' or a color name such as 'red' + * + * fallback + * : 'true' or 'false' whether to enable fallback. If + * disabled, then characters will only be used from the closest + * matching font on the system. No fallback will be done to other + * fonts on the system that might contain the characters in the text. + * Fallback is enabled by default. Most applications should not + * disable fallback. + * + * allow_breaks + * : 'true' or 'false' whether to allow line breaks or not. If + * not allowed, the range will be kept in a single run as far + * as possible. Breaks are allowed by default. + * + * insert_hyphens + * : 'true' or 'false' whether to insert hyphens when breaking + * lines in the middle of a word. Hyphens are inserted by default. + * + * show + * : A value determining how invisible characters are treated. + * Possible values are 'spaces', 'line-breaks', 'ignorables' + * or combinations, such as 'spaces|line-breaks'. + * + * lang + * : A language code, indicating the text language + * + * letter_spacing + * : Inter-letter spacing in 1024ths of a point. + * + * gravity + * : One of 'south', 'east', 'north', 'west', 'auto'. + * + * gravity_hint + * : One of 'natural', 'strong', 'line'. + * + * The following convenience tags are provided: + * + * <b> + * : Bold + * + * <big> + * : Makes font relatively larger, equivalent to <span size="larger"> + * + * <i> + * : Italic + * + * <s> + * : Strikethrough + * + * <sub> + * : Subscript + * + * <sup> + * : Superscript + * + * <small> + * : Makes font relatively smaller, equivalent to <span size="smaller"> + * + * <tt> + * : Monospace + * + * <u> + * : Underline + */ + +/* FIXME */ +#define _(x) x + +/* CSS size levels */ +typedef enum +{ + XXSmall = -3, + XSmall = -2, + Small = -1, + Medium = 0, + Large = 1, + XLarge = 2, + XXLarge = 3 +} SizeLevel;

It has such + * features as anti-aliased primitives, alpha-compositing, and + * gradients. Multiple backends for Cairo are available, to allow + * rendering to images, to PDF files, and to the screen on X and on other + * windowing systems. The functions in this section allow using Pango + * to render to Cairo surfaces. + * + * Using Pango with Cairo is straightforward. A #PangoContext created + * with pango_cairo_font_map_create_context() can be used on any + * Cairo context (cairo_t), but needs to be updated to match the + * current transformation matrix and target surface of the Cairo context + * using pango_cairo_update_context(). The convenience functions + * pango_cairo_create_layout() and pango_cairo_update_layout() handle + * the common case where the program doesn't need to manipulate the + * properties of the #PangoContext. + * + * When you get the metrics of a layout or of a piece of a layout using + * functions such as pango_layout_get_extents(), the reported metrics + * are in user-space coordinates. If a piece of text is 10 units long, + * and you call cairo_scale (cr, 2.0), it still is more-or-less 10 + * units long. However, the results will be affected by hinting + * (that is, the process of adjusting the text to look good on the + * pixel grid), so you shouldn't assume they are completely independent + * of the current transformation matrix.

PangoFcFontMap is the + * major caching container of a Pango system on a Linux desktop. Here is + * a short overview of how it all works. + * + * In short, Fontconfig search patterns are constructed and a fontset loaded + * using them. Here is how we achieve that: + * + * - All FcPattern's referenced by any object in the fontmap are uniquified + * and cached in the fontmap. This both speeds lookups based on patterns + * faster, and saves memory. This is handled by fontmap->priv->pattern_hash. + * The patterns are cached indefinitely. + * + * - The results of a FcFontSort() are used to populate fontsets. However, + * FcFontSort() relies on the search pattern only, which includes the font + * size but not the full font matrix. The fontset however depends on the + * matrix. As a result, multiple fontsets may need results of the + * FcFontSort() on the same input pattern (think rotating text). As such, + * we cache FcFontSort() results in fontmap->priv->patterns_hash which + * is a refcounted structure. This level of abstraction also allows for + * optimizations like calling FcFontMatch() instead of FcFontSort(), and + * only calling FcFontSort() if any patterns other than the first match + * are needed. Another possible optimization would be to call FcFontSort() + * without trimming, and do the trimming lazily as we go. Only pattern sets + * already referenced by a fontset are cached. + * + * - A number of most-recently-used fontsets are cached and reused when + * needed. This is achieved using fontmap->priv->fontset_hash and + * fontmap->priv->fontset_cache. + * + * - All fonts created by any of our fontsets are also cached and reused. + * This is what fontmap->priv->font_hash does. + * + * - Data that only depends on the font file and face index is cached and + * reused by multiple fonts. This includes coverage and cmap cache info. + * This is done using fontmap->priv->font_face_data_hash. + * + * Upon a cache_clear() request, all caches are emptied. All objects (fonts, + * fontsets, faces, families) having a reference from outside will still live + * and may reference the fontmap still, but will not be reused by the fontmap. + * + * + * Todo: + * + * - Make PangoCoverage a GObject and subclass it as PangoFcCoverage which + * will directly use FcCharset.

می‌رم درسامو می‌خونم.» به خدا ما چه می‌دونستیم، به خیالمون عروسی آبجیشه، آقا! فقط با دو نفر دوستیم: مهدی ملخ و حسن گامبو. مهدی از بس مردنیه، همه ملخ صداش می‌کنن. باباش قوری بست می‌زنه. وسط بازی یهو پیداش می‌شه، می‌آد می‌گه: «اگه منو بازی ندین، بازی‌تونو بهم می‌زنم.» اونوقت تا که دس بهش می‌خوره، جیغش می‌ره هوا، میگه: «گه خوردم، گه خوردم.» اونوقت می‌ره از حرصش با میخ یه شکل‌هایی می‌کشه روی دیوار، می‌گه: «این عکس کاظمه.» فسقلی فوتش کنی، قل می‌خوره، ها. آقا، ما دوچرخه خیلی دوست داریم، بعضی وقتا می‌ریم یه تومن می‌دیم چرخ کرایه می‌کنیم. حسن گامبو زورش می‌آد، با سنگ می‌زنه، می‌گه: «منو باید سوار کنی.» من هم می‌بینم داره دلش می‌شکنه، می‌گم: «بیا تو هم سوار شو!» داداش حسن گامبو پنج ماهه رفته لب مرز با خارجیا بجنگه. حسن می‌گه: «رفته امریکا رو نابود کنه، برگرده.» بابای حسن آهنکاره؛ یعنی قالب می‌سازه، پشقاب می‌سازه، همه‌چی می‌سازه. نه که حسن خیکیه، بچه‌ها صداش می‌کنن: «حسن گامبو، سرت تو شامپو!» می‌خواییم با این دو نفر هم قهر کنیم بره. هی می‌آن در خونمون داد می‌زنن: «کاظم، بیا بازی، بیا بازی!» بازی چیه، آقا؟ بده بچه بازی کنه. رفوزه بشیم چه کار؟ دلم می‌خواد دکتر، مهندس، بازنشست، نیرو هوایی، هرچی شد بشیم، بریم پی کارمون بره. ولی تو خونه ما نمی‌شه درس خوند. تا می‌آم بشینم، باید پاشم برم نون بخرم، جارو کنم، خشتک زهرامونو بشورم. پارسال که رفوزه شدم، همه‌ش نیم نمره می‌خواستم قبول بشم. مدرسه‌مونم خیلی هردمبیه، آقا! بچه‌هاش دزدن، می‌آن دفترامونو می‌دزدن. سر کلاس یکی گچ پرت می‌کنه، یکی رو نیمکت ضرب می‌گیره، یکی پا می‌شه می‌رقصه. ما هم که می‌بینیم خر تو خره، حوصله‌مون سر می‌ره، از مدرسه جیم می‌شیم، می‌ریم فروشگاه بزرگ. اونجا پله‌برقی داره. می‌ریم می‌ایستیم خودمونو می‌زینم به اون راه. الکی نگاه می‌کنیم به جنس منس‌ها؛ یعنی مثلا ما هم اومدیم چیز بخریم. بعد می‌ریم سوار پله‌برقی می‌شیم، می‌ریم سواری می‌خوریم، عشق می‌کنیم. آقا، اجازه؟ سه تا دایی هم دارم، آقا! یکی‌شون دایی ضامن، یکی‌شونم دایی مرتضی. اونی که وضعش خوبه اسمش دایی رضوانه. یه وانت داره با یه اتوشویی. تا پامونو می‌ذاریم در دکونش، نامرد یه لگد می‌زنه در اونجامون، می‌گه: «بزن به چاک! باز اومدی از دخل کف ببری» به خدا تهمت می‌زنه، آقا! آقا، به خدا هیچکی به اندازه ما از دزدی بدش نمی‌آد. آقا، دایی مرتضی‌مون اولها کارگر بلورسازی بود، ولی وقتی من هنوز تو دل مادرم بودم، افتاد زندان. یه شب هفت نفر ریختن سرش، اون هم چاقو کشید، زد یکی‌شونو کشت. بعد دادگاه هم اومد بیخودی تقصیر رو گذاشت گردن دایی ما. قبل انقلاب از زندان اومد بیرون، رفت معتاد شد. حالا هم همیشه با زنش دعوا مرافعه داره. گاهی می‌ذاره از خونه‌ش می‌ره، می‌ره می‌ره پیداش نمی‌شه. بعد که برمی‌گرده، الکی به زنش می‌گه، رفته بودم بیمارستان ترک کنم. دایی مرتضی یه بچه کوچولو داره، هروقت می‌آد خونمون، می‌خواد از پله‌هامون بره بالا، بیاد پایین. ما هم می‌ریم دنبالش که نیفته سرش بشکنه. می‌ریم بغلش می‌کنیم. اونوقت می‌ترسه، سفت آدمو می‌گیره. دایی ضامن‌مون توی دولت آباد نفتیه، بعضی روزها که می‌ره نفت پخش کنه منو هم با خودش می‌بره. اون تا می‌ره نفت بده به خونه‌ها، بچه‌ها می‌گیرن مسخره‌م می‌کنن، می‌گن: «ای عرب پا نفتی، کی اومدی، کی رفتی؟» سنگ می‌زنن تو کله‌ام. من هم که زورم نمی‌رسه، گریه‌م می‌گیره. یه روز رفتیم در یه خونه نفت بدیم، اونوقت یه پسره بود - لال بود - دنبالمون کرد تا سر کوچه‌شون. فحش مادر داد، گفت: «دیگه در خونه ما نیا!» لال بود، آقا! نمی‌دونیم چی می‌گفت... آقا، هر وقت از مادرمون حرف می‌زنیم، بغض می‌آد گلومونو می‌گیره، ول‌مون نمی‌کنه... مادرمون سر بچه مرد، آقا! شب درد بچه گرفتش. رفتیم نبات خانومو آوردیم. نبات خانوم مامای محله‌س، شله، یه چشمش هم چپه. صبح که بچه اومد دنیا، مادرمون گذاشت از دنیا رفت. بچه‌ هم پشت سرش مرد، آقا!... مادرمون اون وقت که زنده بود، توی کارخونهٔ استارلایت کار می‌کرد. جوراب شلواری می‌بافت. وقتی شکمش اومد بالا، از اونجا بیرونش کردن. مادرمون اینقده سختی کشیده که خدا بگه، بس! همیشه مریض بود، بعضی وقتا هم غش می‌کرد. پاهاش قد یه متکا باد کرده بود، آقا!... آقا، باور کن، آقا... وقتی مادرمون مرد ما صد برابر الان بغض کردیم. من و زهرا و مصطفی شب تا صبح خوابمون نبرد. بابام اون شب هزار تا سیگار کشید،‌ ولی صبحش مادرمون مرد. وقتی رفتیم خاکش کنیم، ننه غلام نمی‌خواست بذاره ما بریم تماشا، می‌گفت، ما بچه‌ایم، گناه داریم. ولی من دزدکی توی مرده‌شور خونه هم رفتم. بوی بدی می‌ده مرده‌شور خونه، بوی گربهٔ مرده. آدم می‌خواد دل و روده‌شو بالا بیاره. وقتی مادرمونو اوردن گذاشتن توی سالن مرده‌شور خونه، هفت تا مرده زودتر مرده بودن. مادرمون نفر هشتم بود. مرده‌ها منتظر بودن دوش خالی بشه، سر نوبت برن تو، غسل کنن. جنازه یه دختر مدرسه هم بود. نمی‌دونی فک و فامیل دختره چی‌کار می‌کردن؛ یکی سرشو می‌زد به دیوار، یکی کفش‌شو دراورده بود می‌زد تو سر خودش. مادرمونو که اوردن بذارن توی قبر، سروکله‌ٔ مصطفی هم پیداش شد. مادرمون با مصطفی خوب بود. خدا بیامرز که رفت توی قبر، نمی‌دونم از کجا یه مگس اومد نشست روی کفنش. تا مصطفی کیش‌اش کرد، مگسه گذاشت در رفت. بعد شروع کردن با بیل خاک ریختن روی سر مادرمون. رباب خانم با ناخن صورتشو می‌کند. بابام داشت توی دل خودش گریه می‌کرد. اگه مصطفی نمی‌زد زیر گریه و توی خاک و خل غلت نمی‌خورد، من هم گریه نمی‌کردم... مادرمونو که خاک کردیم، دم قبرستان حلوای نذری پخش می‌کردن. واسه اینکه بوی گربهٔ مرده از دماغم بره، یه قاشق حلوا گذاشتم دهنم. ولی صاحب عذا که روشو برگردوند، تفش کردم. آقا، هیچی نمی‌تونستیم بخوریم. آقا، ما دلمون خیلی تنگه، هیشکی نیست ما را زفت کنه. دل‌مون می‌خواد از این دنیا می‌رفتیم. آقا، باورتون نمی‌شه، توی محله ما ملت تند تند می‌میرن، آقا! زهرامون یه همبازی داره، همقد خودشه. اسمش الهامه، پنج سالشه. ده بیست روز پیش باباش از داربست افتاد زمین عکس برگردون شد، مرد. دیروز الهام اومده بود خونه‌مون، یه عکس از باباش هم اورده بود، می‌گفت، هر شب خواب باباشو می‌بینه که اون دنیا آتیش درست کرده، می‌خواد بیاد بگیره اونو کباب کنه بخوره. یه حرفهایی می‌زد که مو به تن آدم سیخ می‌شد. اونوقت شب که خوابم برد، خوابیدم، خواب دیدم عزرائیل و شمر با آتیش اومدن بالای سرم، هی می‌چرخن و چه‌چه می‌خندن. عزرائیل نصفه‌س، آقا! یعنی پا نداره. من هم اومدم از دست‌شون در برم که دیدم یه خرگوشه داره با مامانش قایم موشک بازی می‌کنه. رفتم بگم، من هم بازی که گذاشتن در رفتن. من هم دنبالشون کردم. خسته که شدم دیدم سوار یه قایقم، یه سگ هم داشتم. داشتم با سگ بازی می‌کردم که یهو امیر ریزه پشت پا انداخت، افتادم توی آب. من هم رفتم سوار دوچرخه شدم، زدم به چاک. سگ هم از توی قایق پرید، اومد دنبالم. بعدش دیدم یه هلی‌کوپتر بالای سرمه، می‌خواد باید بستنی لیوانی‌مو قاپ بزنه. من هم با سنگ زدم شیشه‌شو شکوندم. اون هم ترسید در رفت، توی کوچه دباغ‌ها غیب شد. بعدش دیدم عباس آقا گرگ شده، می‌خواد بیاد زهرامونو بگیره لقمه‌ٔ چپش کنه. از ترسم دویدم توی پارک و رفتم سوار تاب شدم. اینقده تاب بازی کردم تا حسابی سرم گیج رفت. اومدم از تاب بپرم پایین، دیدیم زیر پام یه چاهه، یه چاه به این گندگی. داشتم ول می‌شدم ته چاه که از خواب پریدم. نشستم گریه کردم. اونوقت بابام بیدار شد، پرسید: «باز چی شده؟ شاشیدی؟» گفتم: «می‌ترسم.» گفت: «بگیر بخواب بابا تو هم دلت خوشه!» من هم لحافو که کشیدم روی سرم، همه‌ش خدا خدا می‌کردم ایم دفعه که خوابم برد، شانسم بگه، بزنه خواب خوشبختی ببینم، دلم خوش بشه. ولی اگه ما شانس داشتیم، آقا، اسم‌مونو می‌ذاشتن شانسعلی. diff --git a/utils/test-mixed.markup b/utils/test-mixed.markup new file mode 100644 index 00000000..894a1b81 --- /dev/null +++ b/utils/test-mixed.markup @@ -0,0 +1,9 @@ +你好，这是中文竖排测试。 +欢迎来到中国北京。 +白日依山尽， +Roses are Red, +Grass is Green. 2006 +Arabic is گل‌ها قرمزند،‏ +چمن سبز. ۲۰۰۶ +ＡＢＣ 白日依山尽， 2006 +「ノートを買った。」 diff --git a/utils/test-mixed.txt b/utils/test-mixed.txt new file mode 100644 index 00000000..e23f0314 --- /dev/null +++ b/utils/test-mixed.txt @@ -0,0 +1,9 @@ +你好，这是中文竖排测试。 +欢迎来到中国北京。 +白日依山尽， +Roses are Red, +Grass is Green. 2006 +Arabic is گل‌ها قرمزند،‏ +چمن سبز. ۲۰۰۶ +ＡＢＣ 白日依山尽， 2006 +「ノートを買った。」 diff --git a/utils/test-mongolian.txt b/utils/test-mongolian.txt new file mode 100644 index 00000000..9117b7b1 --- /dev/null +++ b/utils/test-mongolian.txt @@ -0,0 +1,15 @@ +ᠡᠷᠲᠡ ᠤᠷᠢᠳᠠ ᠺᠠᠪᠠᠯᠢᠺ ᠪᠠᠯᠭᠠᠰᠤᠨ ᠳᠤᠷ ᠪᠢᠷᠠᠮᠠᠨ ᠤ ᠬᠠᠮᠤᠭ ᠤᠬᠠᠭᠠᠨ ᠤ ᠵᠦᠢᠯ ᠳᠦᠷ ᠮᠡᠷᠭᠡᠨ ᠪᠣᠯᠤᠭᠰᠠᠨ ᠰᠠᠢᠨ ᠲᠥᠷᠥᠯ ᠲᠦ ᠬᠡᠮᠡᠬᠦ +ᠨᠢᠭᠡᠨ ᠪᠢᠷᠠᠮᠠᠨ ᠪᠦᠯᠦᠭᠡ᠃ ᠲᠡᠷᠡ ᠪᠢᠷᠠᠮᠠᠨ ᠳᠤᠷ ᠰᠡᠳᠬᠢᠯ ᠳᠤᠷ ᠲᠠᠭᠠᠯᠠᠬᠤ ᠨᠡᠷᠡᠲᠦ ᠨᠢᠭᠡᠨ ᠬᠠᠲᠤᠭᠲᠠᠢ ᠪᠦᠯᠦᠭᠡ᠃ ᠲᠡᠷᠡ ᠬᠣᠶᠠᠷ  +ᠠᠴᠠ ᠨᠢᠭᠡᠨ ᠬᠥᠪᠡᠭᠦᠨ ᠲᠥᠷᠥᠵᠦᠬᠦᠢ᠃ ᠲᠡᠷᠡ ᠬᠥᠪᠡᠭᠦᠨ ᠢᠨᠤ ᠦᠴᠦᠭᠦᠬᠡᠨ ᠡᠴᠡ ᠭᠡᠭᠡᠨ ᠣᠶᠤᠲᠤ ᠶᠡᠬᠡᠰ ᠦᠨ ᠶᠠᠪᠤᠳᠠᠯ ᠢᠶᠠᠷ ᠶᠠᠪᠤᠭᠴᠢ +ᠨᠢᠭᠡᠨ ᠪᠣᠯᠪᠠᠢ᠃ ᠲᠡᠨᠳᠡ ᠡᠬᠡ ᠢᠨᠤ ᠠᠶ᠎ᠠ ᠡᠨᠡ ᠬᠥᠪᠡᠭᠦᠨ ᠲᠥᠷᠥᠭᠡᠳ ᠰᠠᠴᠠ ᠶᠡᠬᠡᠰ ᠦᠨ ᠶᠠᠪᠤᠳᠠᠯ ᠢᠶᠠᠷ ᠶᠠᠪᠤᠭᠴᠢ ᠭᠡᠭᠡᠨ ᠣᠶᠤᠲᠤ +ᠪᠦᠬᠦ ᠶᠢᠨ ᠲᠤᠯᠠ᠃ ᠮᠠᠭᠠᠳ ᠨᠢᠭᠡᠨ ᠵᠠᠶᠠᠭ᠋᠎ᠠ ᠲᠤ ᠪᠤᠢ ᠵ᠎ᠠ ᠬᠡᠮᠡᠵᠦ᠃ ᠭᠡᠢᠭᠰᠡᠨ ᠬᠡᠮᠡᠨ ᠨᠡᠷ᠎ᠡ ᠥᠭᠭᠦᠭᠡᠳ᠃ ᠠᠢ ᠡᠨᠡ ᠬᠥᠪᠡᠭᠦᠨ  +ᠳ᠋ᠦᠷ ᠬᠠᠮᠤᠭ ᠤᠬᠠᠭᠠᠨ ᠤ ᠵᠦᠢᠯ ᠢ ᠰᠤᠷᠭᠠᠰᠤᠭᠠᠢ ᠬᠡᠮᠡᠵᠦ ᠪᠦᠷᠦᠨ᠃ ᠡᠴᠢᠭᠡ ᠡᠬᠡ ᠬᠣᠶᠠᠷ ᠪᠡᠷ ᠰᠤᠷᠭᠠᠭᠰᠠᠨ ᠳᠤᠷ᠃ ᠳᠥᠷᠪᠡᠯ +ᠦᠭᠡᠢ ᠮᠡᠳᠡᠬᠦᠢ ᠨᠢᠭᠡᠨ ᠪᠣᠯᠪᠠᠢ᠃ ᠲᠡᠷᠡ ᠬᠥᠪᠡᠭᠦᠨ ᠢᠨᠤ ᠳᠣᠯᠣᠭᠠᠨ ᠵᠢᠯ ᠪᠣᠯᠤᠭᠰᠠᠨ ᠳᠤᠷ᠃ ᠪᠢᠷᠠᠮᠠᠨ ᠤ ᠤᠬᠠᠭᠠᠨ ᠤ ᠵᠦᠢᠯ ᠳᠦᠷ +ᠮᠡᠷᠭᠡᠨ ᠪᠣᠯᠤᠭᠰᠠᠨ ᠡᠷᠳᠡᠮ ᠦᠳ ᠢᠨᠤ ᠬᠠᠮᠤᠭ ᠪᠦᠭᠦᠳᠡᠭᠡᠷ ᠲᠦᠷ ᠰᠣᠨᠣᠰᠲᠠᠭᠰᠠᠨ᠋᠎ᠠ᠃ ᠲᠡᠷᠡ ᠴᠠᠭ ᠲᠤᠷ ᠺᠠᠪᠠᠯᠢᠺ ᠪᠠᠯᠭᠠᠰᠤᠨ ᠳᠠᠬᠢᠨ ᠤᠬᠠᠭᠠᠨ ᠤ +ᠵᠦᠢᠯ ᠳᠦᠷ ᠮᠡᠷᠭᠡᠨ ᠪᠣᠯᠤᠭᠰᠠᠨ ᠬᠠᠮᠤᠭ ᠪᠢᠷᠠᠮᠠᠨ ᠴᠢᠭᠤᠯᠵᠤ ᠤᠬᠠᠭᠠᠨ ᠤ ᠵᠦᠢᠯ ᠳᠦᠷ ᠲᠡᠮᠡᠴᠡᠭᠰᠡᠨ ᠳᠦᠷ᠃ ᠪᠢᠷᠠᠮᠠᠨ ᠤ ᠭᠡᠢᠭᠰᠡᠨ ᠬᠥᠪᠡᠭᠦᠨ +ᠮᠠᠱᠢ ᠶᠡᠬᠡ ᠦᠯᠡᠮᠵᠢ ᠪᠣᠯᠤᠭᠰᠠᠨ ᠳᠤᠷ᠃ ᠲᠡᠳᠡᠭᠡᠷ ᠪᠢᠷᠠᠮᠠᠨ ᠥᠭᠦᠯᠡᠷ ᠦᠨ᠃ ᠠᠢ ᠬᠥᠪᠡᠭᠦᠨ ᠠ᠋ ᠨᠠᠰᠤᠨ ᠴᠢᠨᠤ ᠡᠢᠮᠦ ᠵᠠᠯᠠᠭᠤ +ᠪᠥᠭᠡᠲᠡᠯ᠎ᠡ᠃ ᠤᠬᠠᠭᠠᠨ ᠤ ᠵᠦᠢᠯ ᠳᠦᠷ ᠡᠨᠡ ᠮᠡᠲᠦ ᠮᠡᠷᠭᠡᠨ ᠪᠣᠯᠤᠭᠰᠠᠨ ᠬᠡᠷ ᠪᠤᠶᠤ ᠬᠡᠮᠡᠨ ᠠᠰᠠᠭᠪᠠᠰᠤ᠃ ᠬᠥᠪᠡᠭᠦᠨ ᠥᠭᠦᠯᠡᠷ ᠦᠨ᠃ +ᠲᠣᠭᠣᠯᠤᠭᠰᠠᠨ ᠪᠤᠷᠬᠠᠨ ᠪᠡᠷ ᠪᠠᠭᠱᠢ ᠮᠢᠨᠤ ᠪᠤᠢ᠃ ᠪᠣᠭᠳᠠᠰ ᠤᠨ ᠨᠣᠮ ᠪᠡᠷ ᠢᠪᠡᠭᠡᠭᠴᠢ ᠮᠢᠨᠤ ᠪᠤᠢ᠃ ᠪᠤᠷᠰᠠᠩ ᠬᠤᠸᠠᠷᠠᠭ ᠤᠳ ᠪᠡᠷ +ᠤᠳᠤᠷᠢᠳᠳᠤᠭᠴᠢ ᠮᠢᠨᠤ ᠪᠤᠢ᠃ ᠭᠤᠷᠪᠠᠨ ᠡᠷᠳᠡᠨᠢᠰ ᠦᠨ ᠠᠳᠢᠰᠲᠢᠳ ᠬᠢᠭᠰᠡᠨ ᠦ ᠬᠦᠴᠦ ᠪᠡᠷ ᠦᠢᠯᠡ ᠦᠷᠡᠰ ᠲᠦᠷ ᠦᠨᠡᠮᠱᠢᠭᠰᠡᠨ ᠦ ᠲᠤᠯᠠ᠃ +ᠰᠡᠱᠢᠭ ᠦᠭᠡᠢ ᠡᠷᠲᠡ ᠱᠢᠯᠲᠠᠭᠠᠨ ᠤ ᠬᠥᠷᠥᠩᠭᠡ ᠰᠠᠴᠤᠭᠰᠠᠨ ᠳᠤᠷ᠃ ᠦᠷ᠎ᠡ ᠦᠯᠦ ᠬᠣᠮᠰᠠᠳᠬᠤ ᠪᠤᠶᠠᠨ ᠢ ᠬᠢᠴᠢᠶᠡᠭᠰᠡᠨ ᠪᠤᠢ᠃ ᠨᠠᠰᠤᠨ +ᠮᠢᠨᠤ ᠵᠠᠯᠠᠭᠤ ᠪᠣᠯᠪᠠᠰᠤ᠃ ᠤᠬᠠᠭᠠᠨ ᠤ ᠵᠦᠢᠯ ᠳᠦᠷ ᠮᠡᠷᠭᠡᠨ ᠪᠣᠯᠤᠭᠰᠠᠨ ᠤ ᠤᠴᠢᠷ ᠲᠡᠢᠮᠦ ᠪᠤᠢ ᠅ ᠅ diff --git a/utils/test-nko.txt b/utils/test-nko.txt new file mode 100644 index 00000000..65a4347e --- /dev/null +++ b/utils/test-nko.txt @@ -0,0 +1,15 @@ +ߝߘߊ߬ߝߌ߲߬ߠߊ߫ ߟߊ߬ߘߏ߲߬ߞߏ߬ߦߊ߬ߟߌ ߜߙߋ߬ߡߊ߬ߕߍ߰ߟߌ +ߞߖ߭ߊߓߎߟߊ߲ߞߊ ߓߍ߲߬ߡߊ߬ߞߊ߲ ߠߎ߬ : + +ߝߘߊ߬ߝߌ߲߬ߠߊ߫ ߘߎ߰ߙߋ߲ ߠߎ߬ ߟߊ߫ ߢߐ߲߯ߓߍ߲ ߟߊ߬ߘߏ߲߬ߞߏ߬ߦߊ߬ߟߌ ߞߊߡߊ߬ ߞߖ߭ߊߓߎߟߊߟߊ߲ߞߊ߫߸ ( ߞߊ߬ߓߌߛߊ߬ ) ߣߌ߫ ( ߓߌ߬ߛ߭ߊ߯ߙߊ ) ߘߍ߬ߘߊ ߟߎ߬ ߟߊ߫ ߓߊ߯ߙߊ߫ +ߘߊߞߎ߲ ߡߌ߬ߘߊ߬ ߞߣߍ ߞߊ߲߬߸ (IDRC = ߞߣߊߘߊ߫ ߝߘߏ߬ߓߊ߬ ߡߣߊ߬ߙߏ߲߬ߠߌ߲ ߝߊ߲ߓߊ ߞ.ߝ.ߡ.ߝ.) ߞߊ߬ ߡߍ߲ ߖߐ߰ߣߍ ߓߐ߫ ߸ (MTDS = +ߡߊ߬ߙߐߞߎ߫ ߖߊ߬ߥߏ ߟߊ߬ߥߙߎ߬ߞߌ߬ߟߌ ߗߋߢߊߟߌ ߡ.ߖ.ߥߗ.) ߝߊ߬ߙߊ ߘߐ߫ ߊ߬ ߞߊ߲߬ ( ߞߖ߭ߊߓߎߟߊ߲ߞߊ߫ ߕߎߞߑߣߏߔߊߞ ) ߘߍ߬ߞߙߎ ߝߊ߲ߓߊ ߝߍ߬. + +ߞߎ߲߬ߜߙߊ ߣߌ߲߬ ߞߊ߬ ߕߣߐ߬ߓߊ߫ ߛߐ߬ߘߐ߲߬ ߡߊߙߐߞߎ߬ ߖߡߊ߬ߣߊ ߡߊ߬ߞߐ߬ߙߐ߲߬ߞߐ߬ߙߐ߲߬ߠߌ ߞߏߕߌ߮ ߣߴߊ߬ ߣߐ߬ߝߍ߬ ߖߡߊ ߟߊ߫ ߸ ߏ߬ ߟߎ߬ ߡߍ߲ ߠߎ߫ ߣߊ߬ ߘߊ߫ +ߞߏߕߌ߯ ߟߎ߬ ߞߊ߲ߕߌ߮ ߞߐߦߌ߬ߘߊ߬، ߞߊ߬ ߕߐ߬ߣߐ߫ ߛߐ߬ߘߐ߲߬ ߞߣߊߘߊ߫ ߟߊ߬ߛߌ߰ߘߋ߲ ߝߣߊ߫ ߟߊ߫ ߣߊ߬ߟߌ ߣߌ߫ ߜߙߋ߫ ߜߘߍ ߘߎ߰ߙߋ߲߫ ߣߊ߬ߓߊ߮ ߟߎ߬ ߟߊ߫. + +ߕߋ߬ߟߋ߫ ߛߓߊ߬ ߖߊ߬ߣߍ߲߬ ߓߊ߯ߙߊ ߘߝߊߣߍ߲ ߞߐ߫ ߸ ߞߎ߲߬ߜߙߊ ߕߘߍ߬ߒ߬ߘߐ߬ߓߊ߰ߕߐ ߟߎ߫ ߓߍ߲߬ ߘߊ߫ ߞߊ߲߫ ߣߊ߬ߕߐ ߢߌ߲߬ ߠߎ߫ ߡߊ߬ : + +• ߕߟߋ߬ߓߊ߮ ߛߋߒߞߏߟߦߊ ߣߌ߫ ߟߐ߲ߕߊ ( ߕ.ߛ.ߟ.

This results in bindings like PyGI thinking that they are entirely separate arguments, which is an introspection API break (and probably not something that can practically be called any more).

It is + numbered 2 because it goes with version 2 of the ordinary GPL.] + + 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 Library General Public License, applies to some +specially designated Free Software Foundation software, and to any +other libraries whose authors decide to use it. You can use it for +your libraries, 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 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 a program 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. + + Our method of protecting your rights has two steps: (1) copyright +the library, and (2) offer you this license which gives you legal +permission to copy, distribute and/or modify the library. + + Also, for each distributor's protection, we want to make certain +that everyone understands that there is no warranty for this free +library. If the library is modified by someone else and passed on, we +want its recipients to know that what they have is not the original +version, 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 companies distributing free +software will individually obtain patent licenses, thus in effect +transforming the program into proprietary software. To prevent this, +we have made it clear that any patent must be licensed for everyone's +free use or not licensed at all. + + Most GNU software, including some libraries, is covered by the ordinary +GNU General Public License, which was designed for utility programs. This +license, the GNU Library General Public License, applies to certain +designated libraries. This license is quite different from the ordinary +one; be sure to read it in full, and don't assume that anything in it is +the same as in the ordinary license. + + The reason we have a separate public license for some libraries is that +they blur the distinction we usually make between modifying or adding to a +program and simply using it. Linking a program with a library, without +changing the library, is in some sense simply using the library, and is +analogous to running a utility program or application program. However, in +a textual and legal sense, the linked executable is a combined work, a +derivative of the original library, and the ordinary General Public License +treats it as such. + + Because of this blurred distinction, using the ordinary General +Public License for libraries did not effectively promote software +sharing, because most developers did not use the libraries. We +concluded that weaker conditions might promote sharing better. + + However, unrestricted linking of non-free programs would deprive the +users of those programs of all benefit from the free status of the +libraries themselves. This Library General Public License is intended to +permit developers of non-free programs to use free libraries, while +preserving your freedom as a user of such programs to change the free +libraries that are incorporated in them. (We have not seen how to achieve +this as regards changes in header files, but we have achieved it as regards +changes in the actual functions of the Library.) The hope is that this +will lead to faster development of free libraries. + + 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, while the latter only +works together with the library. + + Note that it is possible for a library to be covered by the ordinary +General Public License rather than by this special one. + + GNU LIBRARY GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library which +contains a notice placed by the copyright holder or other authorized +party saying it may be distributed under the terms of this Library +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 compile 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) 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. + + c) 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. + + d) 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 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. + + 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 to +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 Library 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. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO +WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. +EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR +OTHER PARTIES PROVIDE THE LIBRARY "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 +LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME +THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. 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 LIBRARY 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 +LIBRARY (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 LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), 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 Libraries + + If you develop a new library, and you want it to be of the greatest +possible use to the public, we recommend making it free software that +everyone can redistribute and change. You can do so by permitting +redistribution under these terms (or, alternatively, under the terms of the +ordinary General Public License). + + To apply these terms, attach the following notices to the library. 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 library is free software; you can redistribute it and/or + modify it under the terms of the GNU Library General Public + License as published by the Free Software Foundation; either + version 2 of the License, or (at your option) any later version. + + This library 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.

Since the functionality can be generally useful, the API is made + public. + + The pango_extents_to_pixels() function in conjunction with + pango_matrix_transform_rectangle() makes it possible to convert extents to + device space and round then, instead of having to transform rounded + user-space extents. + +- Bugs fixed in this release: + Bug 351496 – PangoAnalysis::gravity breaks binary compatibility + Bug 388702 – Crash when there's no Hangul glyph in the font. + Bug 384543 – FcFontMatch misuse + Bug 392789 – vpath build fails in basic module + Patch from J.

The only exception known to me + is Firefox that adjusts glyph widths to do justification. Most other + uses that do not write to the returned structs (or structs accessible from + them) should be ported to the new readonly API to benefit from major + optimizations (in this case, line extents caching). The list includes, + but is not limited to, Gtk+, SWT, ClassPath, gnome-applets, libgnomeprint, + xmlroff, GtkMathView, Conglomerate, Dia, Anjuta, wxWindows, The Gimp, + and various other applications/libraries: + + http://www.google.com/codesearch?hl=en&q=+pango_layout_(iter_)%3Fget_(lines%3F%7Crun)%5B%5E_%5D&start=50&sa=N + + Worth noting here is that, many uses of pango_layout_get_lines() can be + replaced by a pango_layout_get_iter() that works both more elegantly and + more efficiently.

Pango can be used anywhere that text layout +is needed; however, most of the work on Pango so far has been done using +the GTK widget toolkit as a test platform. Pango forms the core of text +and font handling for GTK. + +Pango is designed to be modular; the core Pango layout can be used +with different font backends.

PangoFcFontMap is the + * major caching container of a Pango system on a Linux desktop. Here is + * a short overview of how it all works. + * + * In short, Fontconfig search patterns are constructed and a fontset loaded + * using them. Here is how we achieve that: + * + * - All FcPattern's referenced by any object in the fontmap are uniquified + * and cached in the fontmap. This both speeds lookups based on patterns + * faster, and saves memory. This is handled by fontmap->priv->pattern_hash. + * The patterns are cached indefinitely. + * + * - The results of a FcFontSort() are used to populate fontsets. However, + * FcFontSort() relies on the search pattern only, which includes the font + * size but not the full font matrix. The fontset however depends on the + * matrix. As a result, multiple fontsets may need results of the + * FcFontSort() on the same input pattern (think rotating text). As such, + * we cache FcFontSort() results in fontmap->priv->patterns_hash which + * is a refcounted structure. This level of abstraction also allows for + * optimizations like calling FcFontMatch() instead of FcFontSort(), and + * only calling FcFontSort() if any patterns other than the first match + * are needed. Another possible optimization would be to call FcFontSort() + * without trimming, and do the trimming lazily as we go. Only pattern sets + * already referenced by a fontset are cached. + * + * - A number of most-recently-used fontsets are cached and reused when + * needed. This is achieved using fontmap->priv->fontset_hash and + * fontmap->priv->fontset_cache. + * + * - All fonts created by any of our fontsets are also cached and reused. + * This is what fontmap->priv->font_hash does. + * + * - Data that only depends on the font file and face index is cached and + * reused by multiple fonts. This includes coverage and cmap cache info. + * This is done using fontmap->priv->font_face_data_hash. + * + * Upon a cache_clear() request, all caches are emptied. All objects (fonts, + * fontsets, faces, families) having a reference from outside will still live + * and may reference the fontmap still, but will not be reused by the fontmap. + * + * + * Todo: + * + * - Make PangoCoverage a GObject and subclass it as PangoFcCoverage which + * will directly use FcCharset.

Be concise but not too +brief. + +Fixes: #1234 +``` + + - Always add a brief description of the commit to the _first_ line of + the commit and terminate by two newlines (it will work without the + second newline, but that is not nice for the interfaces). + + - First line (the brief description) must only be one sentence and + should start with a capital letter unless it starts with a lowercase + symbol or identifier. Don't use a trailing period either. Don't exceed + 72 characters. + + - The main description (the body) is normal prose and should use normal + punctuation and capital letters where appropriate. Consider the commit + message as an email sent to the developers (or yourself, six months + down the line) detailing **why** you changed something. There's no need + to specify the **how**: the changes can be inlined. + + - When committing code on behalf of others use the `--author` option, e.g. + `git commit -a --author "Joe Coder "` and `--signoff`. + + - If your commit is addressing an issue, use the + [GitLab syntax](https://docs.gitlab.com/ce/user/project/issues/automatic_issue_closing.html) + to automatically close the issue when merging the commit with the upstream + repository: + +```plain +Closes #1234 +Fixes #1234 +Closes: https://gitlab.gnome.org/GNOME/gtk/issues/1234 +``` + + - If you have a merge request with multiple commits and none of them + completely fixes an issue, you should add a reference to the issue in + the commit message, e.g. `Bug: #1234`, and use the automatic issue + closing syntax in the description of the merge request. diff --git a/subprojects/gi-docgen/LICENSES/Apache-2.0.txt b/subprojects/gi-docgen/LICENSES/Apache-2.0.txt new file mode 100644 index 00000000..d6456956 --- /dev/null +++ b/subprojects/gi-docgen/LICENSES/Apache-2.0.txt @@ -0,0 +1,202 @@ + + Apache License + Version 2.0, January 2004 + http://www.apache.org/licenses/ + + TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION + + 1.

License Grant. Subject to the terms and conditions of this License, +Licensor hereby grants You a worldwide, royalty-free, non-exclusive, +perpetual (for the duration of the applicable copyright) license to +exercise the rights in the Work as stated below: + + a. to Reproduce the Work, to incorporate the Work into one or more + Collections, and to Reproduce the Work as incorporated in the + Collections; + b. to create and Reproduce Adaptations provided that any such Adaptation, + including any translation in any medium, takes reasonable steps to + clearly label, demarcate or otherwise identify that changes were made + to the original Work. For example, a translation could be marked "The + original work was translated from English to Spanish," or a + modification could indicate "The original work has been modified."; + c. to Distribute and Publicly Perform the Work including as incorporated + in Collections; and, + d. to Distribute and Publicly Perform Adaptations. + e. For the avoidance of doubt: + + i. Non-waivable Compulsory License Schemes. In those jurisdictions in + which the right to collect royalties through any statutory or + compulsory licensing scheme cannot be waived, the Licensor + reserves the exclusive right to collect such royalties for any + exercise by You of the rights granted under this License; + ii. Waivable Compulsory License Schemes. In those jurisdictions in + which the right to collect royalties through any statutory or + compulsory licensing scheme can be waived, the Licensor waives the + exclusive right to collect such royalties for any exercise by You + of the rights granted under this License; and, + iii. Voluntary License Schemes. The Licensor waives the right to + collect royalties, whether individually or, in the event that the + Licensor is a member of a collecting society that administers + voluntary licensing schemes, via that society, from any exercise + by You of the rights granted under this License. + +The above rights may be exercised in all media and formats whether now +known or hereafter devised. The above rights include the right to make +such modifications as are technically necessary to exercise the rights in +other media and formats. Subject to Section 8(f), all rights not expressly +granted by Licensor are hereby reserved. + +4. Restrictions. The license granted in Section 3 above is expressly made +subject to and limited by the following restrictions: + + a. You may Distribute or Publicly Perform the Work only under the terms + of this License. You must include a copy of, or the Uniform Resource + Identifier (URI) for, this License with every copy of the Work You + Distribute or Publicly Perform. You may not offer or impose any terms + on the Work that restrict the terms of this License or the ability of + the recipient of the Work to exercise the rights granted to that + recipient under the terms of the License. You may not sublicense the + Work. You must keep intact all notices that refer to this License and + to the disclaimer of warranties with every copy of the Work You + Distribute or Publicly Perform. When You Distribute or Publicly + Perform the Work, You may not impose any effective technological + measures on the Work that restrict the ability of a recipient of the + Work from You to exercise the rights granted to that recipient under + the terms of the License. This Section 4(a) applies to the Work as + incorporated in a Collection, but this does not require the Collection + apart from the Work itself to be made subject to the terms of this + License. If You create a Collection, upon notice from any Licensor You + must, to the extent practicable, remove from the Collection any credit + as required by Section 4(c), as requested. If You create an + Adaptation, upon notice from any Licensor You must, to the extent + practicable, remove from the Adaptation any credit as required by + Section 4(c), as requested. + b. You may Distribute or Publicly Perform an Adaptation only under the + terms of: (i) this License; (ii) a later version of this License with + the same License Elements as this License; (iii) a Creative Commons + jurisdiction license (either this or a later license version) that + contains the same License Elements as this License (e.g., + Attribution-ShareAlike 3.0 US)); (iv) a Creative Commons Compatible + License. If you license the Adaptation under one of the licenses + mentioned in (iv), you must comply with the terms of that license. If + you license the Adaptation under the terms of any of the licenses + mentioned in (i), (ii) or (iii) (the "Applicable License"), you must + comply with the terms of the Applicable License generally and the + following provisions: (I) You must include a copy of, or the URI for, + the Applicable License with every copy of each Adaptation You + Distribute or Publicly Perform; (II) You may not offer or impose any + terms on the Adaptation that restrict the terms of the Applicable + License or the ability of the recipient of the Adaptation to exercise + the rights granted to that recipient under the terms of the Applicable + License; (III) You must keep intact all notices that refer to the + Applicable License and to the disclaimer of warranties with every copy + of the Work as included in the Adaptation You Distribute or Publicly + Perform; (IV) when You Distribute or Publicly Perform the Adaptation, + You may not impose any effective technological measures on the + Adaptation that restrict the ability of a recipient of the Adaptation + from You to exercise the rights granted to that recipient under the + terms of the Applicable License. This Section 4(b) applies to the + Adaptation as incorporated in a Collection, but this does not require + the Collection apart from the Adaptation itself to be made subject to + the terms of the Applicable License. + c. If You Distribute, or Publicly Perform the Work or any Adaptations or + Collections, You must, unless a request has been made pursuant to + Section 4(a), keep intact all copyright notices for the Work and + provide, reasonable to the medium or means You are utilizing: (i) the + name of the Original Author (or pseudonym, if applicable) if supplied, + and/or if the Original Author and/or Licensor designate another party + or parties (e.g., a sponsor institute, publishing entity, journal) for + attribution ("Attribution Parties") in Licensor's copyright notice, + terms of service or by other reasonable means, the name of such party + or parties; (ii) the title of the Work if supplied; (iii) to the + extent reasonably practicable, the URI, if any, that Licensor + specifies to be associated with the Work, unless such URI does not + refer to the copyright notice or licensing information for the Work; + and (iv) , consistent with Ssection 3(b), in the case of an + Adaptation, a credit identifying the use of the Work in the Adaptation + (e.g., "French translation of the Work by Original Author," or + "Screenplay based on original Work by Original Author"). The credit + required by this Section 4(c) may be implemented in any reasonable + manner; provided, however, that in the case of a Adaptation or + Collection, at a minimum such credit will appear, if a credit for all + contributing authors of the Adaptation or Collection appears, then as + part of these credits and in a manner at least as prominent as the + credits for the other contributing authors. For the avoidance of + doubt, You may only use the credit required by this Section for the + purpose of attribution in the manner set out above and, by exercising + Your rights under this License, You may not implicitly or explicitly + assert or imply any connection with, sponsorship or endorsement by the + Original Author, Licensor and/or Attribution Parties, as appropriate, + of You or Your use of the Work, without the separate, express prior + written permission of the Original Author, Licensor and/or Attribution + Parties. + d. Except as otherwise agreed in writing by the Licensor or as may be + otherwise permitted by applicable law, if You Reproduce, Distribute or + Publicly Perform the Work either by itself or as part of any + Adaptations or Collections, You must not distort, mutilate, modify or + take other derogatory action in relation to the Work which would be + prejudicial to the Original Author's honor or reputation. Licensor + agrees that in those jurisdictions (e.g. Japan), in which any exercise + of the right granted in Section 3(b) of this License (the right to + make Adaptations) would be deemed to be a distortion, mutilation, + modification or other derogatory action prejudicial to the Original + Author's honor and reputation, the Licensor will waive or not assert, + as appropriate, this Section, to the fullest extent permitted by the + applicable national law, to enable You to reasonably exercise Your + right under Section 3(b) of this License (right to make Adaptations) + but not otherwise. + +5. Representations, Warranties and Disclaimer + +UNLESS OTHERWISE MUTUALLY AGREED TO BY THE PARTIES IN WRITING, LICENSOR +OFFERS THE WORK AS-IS AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY +KIND CONCERNING THE WORK, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE, +INCLUDING, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTIBILITY, +FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT, OR THE ABSENCE OF +LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OF ABSENCE OF ERRORS, +WHETHER OR NOT DISCOVERABLE. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION +OF IMPLIED WARRANTIES, SO SUCH EXCLUSION MAY NOT APPLY TO YOU. + +6. Limitation on Liability. EXCEPT TO THE EXTENT REQUIRED BY APPLICABLE +LAW, IN NO EVENT WILL LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY FOR +ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES +ARISING OUT OF THIS LICENSE OR THE USE OF THE WORK, EVEN IF LICENSOR HAS +BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. + +7. Termination + + a. This License and the rights granted hereunder will terminate + automatically upon any breach by You of the terms of this License. + Individuals or entities who have received Adaptations or Collections + from You under this License, however, will not have their licenses + terminated provided such individuals or entities remain in full + compliance with those licenses. Sections 1, 2, 5, 6, 7, and 8 will + survive any termination of this License. + b. Subject to the above terms and conditions, the license granted here is + perpetual (for the duration of the applicable copyright in the Work). + Notwithstanding the above, Licensor reserves the right to release the + Work under different license terms or to stop distributing the Work at + any time; provided, however that any such election will not serve to + withdraw this License (or any other license that has been, or is + required to be, granted under the terms of this License), and this + License will continue in full force and effect unless terminated as + stated above. + +8. Miscellaneous + + a. Each time You Distribute or Publicly Perform the Work or a Collection, + the Licensor offers to the recipient a license to the Work on the same + terms and conditions as the license granted to You under this License. + b. Each time You Distribute or Publicly Perform an Adaptation, Licensor + offers to the recipient a license to the original Work on the same + terms and conditions as the license granted to You under this License. + c. If any provision of this License is invalid or unenforceable under + applicable law, it shall not affect the validity or enforceability of + the remainder of the terms of this License, and without further action + by the parties to this agreement, such provision shall be reformed to + the minimum extent necessary to make such provision valid and + enforceable. + d. No term or provision of this License shall be deemed waived and no + breach consented to unless such waiver or consent shall be in writing + and signed by the party to be charged with such waiver or consent. + e. This License constitutes the entire agreement between the parties with + respect to the Work licensed here. There are no understandings, + agreements or representations with respect to the Work not specified + here. Licensor shall not be bound by any additional provisions that + may appear in any communication from You. This License may not be + modified without the mutual written agreement of the Licensor and You. + f. The rights granted under, and the subject matter referenced, in this + License were drafted utilizing the terminology of the Berne Convention + for the Protection of Literary and Artistic Works (as amended on + September 28, 1979), the Rome Convention of 1961, the WIPO Copyright + Treaty of 1996, the WIPO Performances and Phonograms Treaty of 1996 + and the Universal Copyright Convention (as revised on July 24, 1971). + These rights and subject matter take effect in the relevant + jurisdiction in which the License terms are sought to be enforced + according to the corresponding provisions of the implementation of + those treaty provisions in the applicable national law. If the + standard suite of rights granted under applicable copyright law + includes additional rights not granted under this License, such + additional rights are deemed to be included in the License; this + License is not intended to restrict the license of any rights under + applicable law. + + +Creative Commons Notice + + Creative Commons is not a party to this License, and makes no warranty + whatsoever in connection with the Work.

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

This also includes volunteers, maintainers, leaders, contributors, contribution reviewers, issue reporters, GNOME users, and anyone participating in discussion in GNOME online spaces. + +## Reporting an Incident + +If you believe that someone is violating the Code of Conduct, or have +any other concerns, please [contact the Code of Conduct committee](https://wiki.gnome.org/Foundation/CodeOfConduct/ReporterGuide). + +## Our Standards + +The GNOME online community is dedicated to providing a positive experience for everyone, regardless of: + + * age + * body size + * caste + * citizenship + * disability + * education + * ethnicity + * familial status + * gender expression + * gender identity + * genetic information + * immigration status + * level of experience + * nationality + * personal appearance + * pregnancy + * race + * religion + * sex characteristics + * sexual orientation + * sexual identity + * socio-economic status + * tribe + * veteran status + +### Community Guidelines + +Examples of behavior that contributes to creating a positive environment include: + + * **Be friendly.** Use welcoming and inclusive language. + * **Be empathetic.** Be respectful of differing viewpoints and experiences. + * **Be respectful.** When we disagree, we do so in a polite and constructive manner. + * **Be considerate.** Remember that decisions are often a difficult choice between competing priorities. Focus on what is best for the community. Keep discussions around technology choices constructive and respectful. + * **Be patient and generous.** If someone asks for help it is because they need it. When documentation is available that answers the question, politely point them to it. If the question is off-topic, suggest a more appropriate online space to seek help. + * **Try to be concise.** Read the discussion before commenting in order to not repeat a point that has been made. + +### Inappropriate Behavior + +Community members asked to stop any inappropriate behavior are expected to comply immediately. + +We want all participants in the GNOME community have the best possible experience they can. In order to be clear what that means, we've provided a list of examples of behaviors that are inappropriate for GNOME community spaces: + + * **Deliberate intimidation, stalking, or following.** + * **Sustained disruption of online discussion, talks, or other events.** Sustained disruption of events, online discussions, or meetings, including talks and presentations, will not be tolerated. This includes 'Talking over' or 'heckling' event speakers or influencing crowd actions that cause hostility in event sessions. Sustained disruption also includes drinking alcohol to excess or using recreational drugs to excess, or pushing others to do so. + * **Harassment of people who don't drink alcohol.** We do not tolerate derogatory comments about those who abstain from alcohol or other substances. We do not tolerate pushing people to drink, talking about their abstinence or preferences to others, or pressuring them to drink - physically or through jeering. + * **Sexist, racist, homophobic, transphobic, ableist language or otherwise exclusionary language.** This includes deliberately referring to someone by a gender that they do not identify with, and/or questioning the legitimacy of an individual's gender identity. If you're unsure if a word is derogatory, don't use it. This also includes repeated subtle and/or indirect discrimination. + * **Unwelcome sexual attention or behavior that contributes to a sexualized environment.** This includes sexualized comments, jokes or imagery in interactions, communications or presentation materials, as well as inappropriate touching, groping, or sexual advances. Sponsors should not use sexualized images, activities, or other material. Meetup organizing staff and other volunteer organizers should not use sexualized clothing/uniforms/costumes, or otherwise create a sexualized environment. + * **Unwelcome physical contact.** This includes touching a person without permission, including sensitive areas such as their hair, pregnant stomach, mobility device (wheelchair, scooter, etc) or tattoos. This also includes physically blocking or intimidating another person. Physical contact or simulated physical contact (such as emojis like "kiss") without affirmative consent is not acceptable. This includes sharing or distribution of sexualized images or text. + * **Violence or threats of violence.** Violence and threats of violence are not acceptable - online or offline. This includes incitement of violence toward any individual, including encouraging a person to commit self-harm. This also includes posting or threatening to post other people's personally identifying information ("doxxing") online. + * **Influencing or encouraging inappropriate behavior.** If you influence or encourage another person to violate the Code of Conduct, you may face the same consequences as if you had violated the Code of Conduct. + * **Possession of an offensive weapon at a GNOME event.** This includes anything deemed to be a weapon by the event organizers. + +The GNOME community prioritizes marginalized people's safety over privileged people's comfort. The committee will not act on complaints regarding: + + * "Reverse"-isms, including "reverse racism," "reverse sexism," and "cisphobia" + * Reasonable communication of boundaries, such as "leave me alone," "go away," or "I'm not discussing this with you." + * Criticizing racist, sexist, cissexist, or otherwise oppressive behavior or assumptions + * Communicating boundaries or criticizing oppressive behavior in a "tone" you don't find congenial + +The examples listed above are not against the Code of Conduct. If you have questions about the above statements, please [read this document](https://github.com/sagesharp/code-of-conduct-template/blob/master/code-of-conduct/example-reversisms.md#supporting-diversity). + +If a participant engages in behavior that violates this code of conduct, the GNOME Code of Conduct committee may take any action they deem appropriate.

هر روز هر روز کتک. بابام دیشب بیخودی مصطفی رو گرفت زد. گرفت زدش گفت: «چرا وقتی می‌ری دست به آب، سر پا می‌شاشی؟ بشی بشاش!» مصطفی‌مون هیچی حالیش نمی‌شه. قد زهرامون بوده که از بالا پشت بوم افتاده، رگ کله‌اش تکون خرده. حالا سیزده سالشه. نه چارده،‌ چارده سالشه. داداش بزرگ‌ مونه. الان مدرسه عقب افتاده‌ها درس می‌خونه. آب، بابا، بار میخونه یاد بگیره، بیاد جلو. دو سه کلمه بلده حرف بزنه ولی چیزه... نمیتونه قشنگ حرف بزنه. بابام می‌خواد از مدرسه ورش داره، بذاره یه جا که کار یاد بگیره. بابا زهرا را از همه بیشتر می‌خواد. اون هم هر کاری دلش بخواد می‌کنه. هرچی می‌گیم گوش نمی‌کنه، می‌ره تو جوب محل کثافت‌کاری می‌کنه. اون روزی حواسم نبود، رفت یه مشت دیگ مونده سر کوچه بود ورداشت خورد. شب دلش درد گرفت نزدیک بود بمیره. اونوقت بابام اومد گرفت منو با شیلنگ کشت. آقا مگه شهر هرته؟ خر کتک می‌خوره. دیگه چرا ما رو می‌زنن؟ برن به خر بزنن! آخه من که نمی‌تونم همه‌ش مواظب زهرا باشم. راستی یه صاحب حیاط داریم، خیلی بد اخلاقه آقا! اسمش عباس آقاس. صبح می‌ره ظهر می‌آد. سپور شهرداریه. بیست و چار ساعت می‌آد بند میکنه به ما، میگه: «آب زیاد مصرف نکنین، چاه پر میشه.» زهرامون که گاهی گریه می‌کنه، دادش بلند می‌شه می‌گه: «صدای این تخم‌سگو خفه کنین!» اونوقت که مادرمون زنده بود، یه دفعه می‌خواست از دست عباس آقا نفت بریزه سرش، خودشو آتیش بزنه. عباس آقا اصلاً رحم حالیش نمی‌شه؛ پسر سیزده ساله‌شو گرفته از خونه انداخته بیرون. اون هم رفته توی کوچه‌ پس ‌کوچه‌‌ها ول شده. حالا خدا می‌دونه کجاس، چه کار می‌کنه،‌ از کجا می‌آره می‌خوره. بچه‌ها می‌گن: «شب‌ها می‌ره توی پارک‌ها پیش سگها می‌خوابه.» که رفته دهات خونهٔ باباش، می‌گه دیگه نمی‌آم تهران. آقا، ما هم دلمون می‌خواد میرفتیم دهمون با گوسفندها بازی می‌کردیم؛ با بابا بزرگ‌مون می‌رفتیم دشت بز می‌چروندیم،‌ بادوم پاک می‌کردیم، انگور می‌چیدیم. دهمون ولی خیلی دوره آخه! زن عباس آقا حق داره، آقا! محله‌مون خیلی بده. هر روز اونجا دعواس، دعوا، چاقو کشی. توی خرابه هم پر معتاده، بگی دوهزار تا هم بیشتر. می‌رن اونجا قمار می‌کنن، شیره می‌کشن، آمپول می‌زنن تو رگشون. ماهم از ترس معتادها جرأت نمی‌کنیم از خونه بریم کوچه، یه ذره بازی کنیم. از کمیته‌م نمی‌ترسن، میگیرن بچه‌های مردمو می‌دزدن، میبرن توی کوره‌ها،‌ توی دلاشون چیز قایم می‌کنن؛ هروئین قایم میکنن. یه امیر ریزه هست تریاکیه، اون روزی اومد خرم کنه، گفت: «بیا سوار ماشین بشیم، بریم یه جائی.» من هم از ترسم خر نشدم. یه چیز خنده دار بگم بخندی، آقا: اینورمون یه همسایه داریم، اسمش ربابه. انوقت توپ،‌ لنگه کفش، تنکه، هرچی بیفته خونشون،‌ شوهرش ور می‌داره می‌اندازه توی آب انبارشون. هروقت هم کوچه شلوغ بشه، شوهر رباب می‌آد بیرون می‌گه: «واق، عو!» اون هم مث مصطفی‌ ما لقوه‌ایه‌؛ دستش می‌لزره، همه جاش می‌لرزه. اون روز اومد دم دکون، رفت اونور جوب نشت. این یکی همسایه‌مون رفت یه کتاب دربارهٔ خدا و فرشته‌ها آورد براش خوند. رباب خانم خودش خونه یه اعیونه کار می‌کنه؛ چیزاشونو می‌شوره، باغ‌شونو آب می‌ده؛ کلفتی می‌کنه. بعد همه‌ش می‌آد پز اربابشو می‌ده. الان دیگه همه اهل محل می‌دونن باغ خونهٔ ارباب رباب خانوم اندازه پارک شهره. استخرش از مال پارک شهر هم گنده‌تره. هروقت هم که ارباب می‌خواد‌ آبتنی کنه،‌ اول یه قطره دوای مخصوص هست، می‌ریزه توی استخر که آب‌شو می‌کنه مث اشک چشم. بعد می‌ره زیر دوش، با عطر و گلاب خودشو می‌شوره. بعد می‌پره توی استخر، می‌گیره شوخی شوخی آب می‌پاشه به رباب خانوم. زن اربابش هم خارجیه. مال همون کشوریه که شیش ماه شبه، شیش ماه روز. رباب یه چاخان‌هایی می‌کنه که کلهٔ آدم سوت می‌کشه! می‌گه ارباب یه سگ پشمالو داره،‌ اسمش مونیکاس. قسم می‌خوره می‌گه مونیکا غذاشو با کارد و چنگال می‌خوره. اللَه اکبر به این دروغ. یه پیرزنه هم هست سر کوچمونه. با خودش تنهایی زندگی می‌کنه. اسمش ننه غلامه. هشتاد نود سالشه ولی خجالت نمی‌کشه،‌ از امریکا خوشش می‌آد. همه ازش می‌ترسن؛ هر وفت بیاد بیرون، فحش می‌ده، جیغ و ویغ می‌زنه. مثلا من اذیتش کردم، می‌آد سر فحش‌رو می‌کشه به تو. وقتی بچه‌ها بخوان لج‌شو در‌بیارن، می‌گن: «مرگ بر امریکا!» اونوقت اون هم حرصش می‌گیره، هزار تا فحش بی‌ناموسی و خوار و مادر می‌کشه به جون همه. ننه غلام دیونه‌س. بعضی وقتا هم با‌ آدم خوبه. یه روز من و زهرا رو گرفت به زور برد خونه‌ش، کله پاچه داد، گفت «بخورین!» ما هم خوردیم. ته کاسه یه لقمه موند که روش یه عالمه مو بود. گفت: «اگه نخورین با همین چاقو سرتونو می‌برم.» ما هم از ترس جونمون خوردیم. ننه غلام وقتی سر حاله، چیز می‌آره می‌ده آدم. مثلا یکی زخمه،‌ دوا می‌آره بهش می‌ده. مثلا کسی چیزی نداره، چیز می‌آره بهش می‌ده، وسط کوچه‌مون یه خونه‌س که دخترهاش خرابن، آقا. اونوقت شیره‌ای‌ها و چاقوکش‌ها می‌رن خونه‌شون، کار بد می‌کنن. بعضی وقتا هم دختر‌هاش لباس سرخ و زرد تن می‌کنن و کفش پاشنه بلند تق‌تقی می‌پوشن، می‌رن واسه بالاشهری‌ها قر می‌دن. یه دفعه هم داشتم می‌رفتم پیش بچه‌ها «لیس پس لیس» بازی کنم که دختر کوچیکه‌ش امیر ریزه رو صدا کرد و بهش گفت: «تو چقدر پاهات لاغره!» بعد امیر ریزه هم نامردی نکرد. گفت:«خودت چرا لمبه‌هات چاقه؟» بعد دوتایی کرکر خندیدن. خودم با همین دو تا چشمام دیدم، آقا! اونوقت ما هم که می‌بینیم محله‌مون پر از بی‌تربیتی‌یه، زدیم با هفت‌تا از بچه محلامون قهر کردیم. با اون هفت‌تا هم بمیرم آشتی نمی‌کنم، آقا. با یکی‌شون یه ساله قهریم، اسمش محمده. یه روز سر کوچه‌مون عروسی بود، ما هم داشتیم بازی می‌کردیم. من دراومدم به محمد گفتم: «محمد امشب چه خبره؟ آبجی‌ت می‌ره حجله؟» ناراحت شد، گفت: «باهات قهرم.» من هم گفتم: «چه بهتر! می‌رم درسامو می‌خونم.» به خدا ما چه می‌دونستیم، به خیالمون عروسی آبجیشه، آقا! فقط با دو نفر دوستیم: مهدی ملخ و حسن گامبو. مهدی از بس مردنیه، همه ملخ صداش می‌کنن. باباش قوری بست می‌زنه. وسط بازی یهو پیداش می‌شه، می‌آد می‌گه: «اگه منو بازی ندین، بازی‌تونو بهم می‌زنم.» اونوقت تا که دس بهش می‌خوره، جیغش می‌ره هوا، میگه: «گه خوردم، گه خوردم.» اونوقت می‌ره از حرصش با میخ یه شکل‌هایی می‌کشه روی دیوار، می‌گه: «این عکس کاظمه.» فسقلی فوتش کنی، قل می‌خوره، ها. آقا، ما دوچرخه خیلی دوست داریم، بعضی وقتا می‌ریم یه تومن می‌دیم چرخ کرایه می‌کنیم. حسن گامبو زورش می‌آد، با سنگ می‌زنه، می‌گه: «منو باید سوار کنی.» من هم می‌بینم داره دلش می‌شکنه، می‌گم: «بیا تو هم سوار شو!» داداش حسن گامبو پنج ماهه رفته لب مرز با خارجیا بجنگه. حسن می‌گه: «رفته امریکا رو نابود کنه، برگرده.» بابای حسن آهنکاره؛ یعنی قالب می‌سازه، پشقاب می‌سازه، همه‌چی می‌سازه. نه که حسن خیکیه، بچه‌ها صداش می‌کنن: «حسن گامبو، سرت تو شامپو!» می‌خواییم با این دو نفر هم قهر کنیم بره. هی می‌آن در خونمون داد می‌زنن: «کاظم، بیا بازی، بیا بازی!» بازی چیه، آقا؟ بده بچه بازی کنه. رفوزه بشیم چه کار؟ دلم می‌خواد دکتر، مهندس، بازنشست، نیرو هوایی، هرچی شد بشیم، بریم پی کارمون بره. ولی تو خونه ما نمی‌شه درس خوند. تا می‌آم بشینم، باید پاشم برم نون بخرم، جارو کنم، خشتک زهرامونو بشورم. پارسال که رفوزه شدم، همه‌ش نیم نمره می‌خواستم قبول بشم. مدرسه‌مونم خیلی هردمبیه، آقا! بچه‌هاش دزدن، می‌آن دفترامونو می‌دزدن. سر کلاس یکی گچ پرت می‌کنه، یکی رو نیمکت ضرب می‌گیره، یکی پا می‌شه می‌رقصه. ما هم که می‌بینیم خر تو خره، حوصله‌مون سر می‌ره، از مدرسه جیم می‌شیم، می‌ریم فروشگاه بزرگ. اونجا پله‌برقی داره. می‌ریم می‌ایستیم خودمونو می‌زینم به اون راه. الکی نگاه می‌کنیم به جنس منس‌ها؛ یعنی مثلا ما هم اومدیم چیز بخریم. بعد می‌ریم سوار پله‌برقی می‌شیم، می‌ریم سواری می‌خوریم، عشق می‌کنیم. آقا، اجازه؟ سه تا دایی هم دارم، آقا! یکی‌شون دایی ضامن، یکی‌شونم دایی مرتضی. اونی که وضعش خوبه اسمش دایی رضوانه. یه وانت داره با یه اتوشویی. تا پامونو می‌ذاریم در دکونش، نامرد یه لگد می‌زنه در اونجامون، می‌گه: «بزن به چاک! باز اومدی از دخل کف ببری» به خدا تهمت می‌زنه، آقا! آقا، به خدا هیچکی به اندازه ما از دزدی بدش نمی‌آد. آقا، دایی مرتضی‌مون اولها کارگر بلورسازی بود، ولی وقتی من هنوز تو دل مادرم بودم، افتاد زندان. یه شب هفت نفر ریختن سرش، اون هم چاقو کشید، زد یکی‌شونو کشت. بعد دادگاه هم اومد بیخودی تقصیر رو گذاشت گردن دایی ما. قبل انقلاب از زندان اومد بیرون، رفت معتاد شد. حالا هم همیشه با زنش دعوا مرافعه داره. گاهی می‌ذاره از خونه‌ش می‌ره، می‌ره می‌ره پیداش نمی‌شه. بعد که برمی‌گرده، الکی به زنش می‌گه، رفته بودم بیمارستان ترک کنم. دایی مرتضی یه بچه کوچولو داره، هروقت می‌آد خونمون، می‌خواد از پله‌هامون بره بالا، بیاد پایین. ما هم می‌ریم دنبالش که نیفته سرش بشکنه. می‌ریم بغلش می‌کنیم. اونوقت می‌ترسه، سفت آدمو می‌گیره. دایی ضامن‌مون توی دولت آباد نفتیه، بعضی روزها که می‌ره نفت پخش کنه منو هم با خودش می‌بره. اون تا می‌ره نفت بده به خونه‌ها، بچه‌ها می‌گیرن مسخره‌م می‌کنن، می‌گن: «ای عرب پا نفتی، کی اومدی، کی رفتی؟» سنگ می‌زنن تو کله‌ام. من هم که زورم نمی‌رسه، گریه‌م می‌گیره. یه روز رفتیم در یه خونه نفت بدیم، اونوقت یه پسره بود - لال بود - دنبالمون کرد تا سر کوچه‌شون. فحش مادر داد، گفت: «دیگه در خونه ما نیا!» لال بود، آقا! نمی‌دونیم چی می‌گفت... آقا، هر وقت از مادرمون حرف می‌زنیم، بغض می‌آد گلومونو می‌گیره، ول‌مون نمی‌کنه... مادرمون سر بچه مرد، آقا! شب درد بچه گرفتش. رفتیم نبات خانومو آوردیم. نبات خانوم مامای محله‌س، شله، یه چشمش هم چپه. صبح که بچه اومد دنیا، مادرمون گذاشت از دنیا رفت. بچه‌ هم پشت سرش مرد، آقا!... مادرمون اون وقت که زنده بود، توی کارخونهٔ استارلایت کار می‌کرد. جوراب شلواری می‌بافت. وقتی شکمش اومد بالا، از اونجا بیرونش کردن. مادرمون اینقده سختی کشیده که خدا بگه، بس! همیشه مریض بود، بعضی وقتا هم غش می‌کرد. پاهاش قد یه متکا باد کرده بود، آقا!... آقا، باور کن، آقا... وقتی مادرمون مرد ما صد برابر الان بغض کردیم. من و زهرا و مصطفی شب تا صبح خوابمون نبرد. بابام اون شب هزار تا سیگار کشید،‌ ولی صبحش مادرمون مرد. وقتی رفتیم خاکش کنیم، ننه غلام نمی‌خواست بذاره ما بریم تماشا، می‌گفت، ما بچه‌ایم، گناه داریم. ولی من دزدکی توی مرده‌شور خونه هم رفتم. بوی بدی می‌ده مرده‌شور خونه، بوی گربهٔ مرده. آدم می‌خواد دل و روده‌شو بالا بیاره. وقتی مادرمونو اوردن گذاشتن توی سالن مرده‌شور خونه، هفت تا مرده زودتر مرده بودن. مادرمون نفر هشتم بود. مرده‌ها منتظر بودن دوش خالی بشه، سر نوبت برن تو، غسل کنن. جنازه یه دختر مدرسه هم بود. نمی‌دونی فک و فامیل دختره چی‌کار می‌کردن؛ یکی سرشو می‌زد به دیوار، یکی کفش‌شو دراورده بود می‌زد تو سر خودش. مادرمونو که اوردن بذارن توی قبر، سروکله‌ٔ مصطفی هم پیداش شد. مادرمون با مصطفی خوب بود. خدا بیامرز که رفت توی قبر، نمی‌دونم از کجا یه مگس اومد نشست روی کفنش. تا مصطفی کیش‌اش کرد، مگسه گذاشت در رفت. بعد شروع کردن با بیل خاک ریختن روی سر مادرمون. رباب خانم با ناخن صورتشو می‌کند. بابام داشت توی دل خودش گریه می‌کرد. اگه مصطفی نمی‌زد زیر گریه و توی خاک و خل غلت نمی‌خورد، من هم گریه نمی‌کردم... مادرمونو که خاک کردیم، دم قبرستان حلوای نذری پخش می‌کردن. واسه اینکه بوی گربهٔ مرده از دماغم بره، یه قاشق حلوا گذاشتم دهنم. ولی صاحب عذا که روشو برگردوند، تفش کردم. آقا، هیچی نمی‌تونستیم بخوریم. آقا، ما دلمون خیلی تنگه، هیشکی نیست ما را زفت کنه. دل‌مون می‌خواد از این دنیا می‌رفتیم. آقا، باورتون نمی‌شه، توی محله ما ملت تند تند می‌میرن، آقا! زهرامون یه همبازی داره، همقد خودشه. اسمش الهامه، پنج سالشه. ده بیست روز پیش باباش از داربست افتاد زمین عکس برگردون شد، مرد. دیروز الهام اومده بود خونه‌مون، یه عکس از باباش هم اورده بود، می‌گفت، هر شب خواب باباشو می‌بینه که اون دنیا آتیش درست کرده، می‌خواد بیاد بگیره اونو کباب کنه بخوره. یه حرفهایی می‌زد که مو به تن آدم سیخ می‌شد. اونوقت شب که خوابم برد، خوابیدم، خواب دیدم عزرائیل و شمر با آتیش اومدن بالای سرم، هی می‌چرخن و چه‌چه می‌خندن. عزرائیل نصفه‌س، آقا! یعنی پا نداره. من هم اومدم از دست‌شون در برم که دیدم یه خرگوشه داره با مامانش قایم موشک بازی می‌کنه. رفتم بگم، من هم بازی که گذاشتن در رفتن. من هم دنبالشون کردم. خسته که شدم دیدم سوار یه قایقم، یه سگ هم داشتم. داشتم با سگ بازی می‌کردم که یهو امیر ریزه پشت پا انداخت، افتادم توی آب. من هم رفتم سوار دوچرخه شدم، زدم به چاک. سگ هم از توی قایق پرید، اومد دنبالم. بعدش دیدم یه هلی‌کوپتر بالای سرمه، می‌خواد باید بستنی لیوانی‌مو قاپ بزنه. من هم با سنگ زدم شیشه‌شو شکوندم. اون هم ترسید در رفت، توی کوچه دباغ‌ها غیب شد. بعدش دیدم عباس آقا گرگ شده، می‌خواد بیاد زهرامونو بگیره لقمه‌ٔ چپش کنه. از ترسم دویدم توی پارک و رفتم سوار تاب شدم. اینقده تاب بازی کردم تا حسابی سرم گیج رفت. اومدم از تاب بپرم پایین، دیدیم زیر پام یه چاهه، یه چاه به این گندگی. داشتم ول می‌شدم ته چاه که از خواب پریدم. نشستم گریه کردم. اونوقت بابام بیدار شد، پرسید: «باز چی شده؟ شاشیدی؟» گفتم: «می‌ترسم.» گفت: «بگیر بخواب بابا تو هم دلت خوشه!» من هم لحافو که کشیدم روی سرم، همه‌ش خدا خدا می‌کردم ایم دفعه که خوابم برد، شانسم بگه، بزنه خواب خوشبختی ببینم، دلم خوش بشه. ولی اگه ما شانس داشتیم، آقا، اسم‌مونو می‌ذاشتن شانسعلی. diff --git a/utils/test-mixed.markup b/utils/test-mixed.markup new file mode 100644 index 00000000..894a1b81 --- /dev/null +++ b/utils/test-mixed.markup @@ -0,0 +1,9 @@ +你好，这是中文竖排测试。 +欢迎来到中国北京。 +白日依山尽， +Roses are Red, +Grass is Green. 2006 +Arabic is گل‌ها قرمزند،‏ +چمن سبز. ۲۰۰۶ +ＡＢＣ 白日依山尽， 2006 +「ノートを買った。」 diff --git a/utils/test-mixed.txt b/utils/test-mixed.txt new file mode 100644 index 00000000..e23f0314 --- /dev/null +++ b/utils/test-mixed.txt @@ -0,0 +1,9 @@ +你好，这是中文竖排测试。 +欢迎来到中国北京。 +白日依山尽， +Roses are Red, +Grass is Green. 2006 +Arabic is گل‌ها قرمزند،‏ +چمن سبز. ۲۰۰۶ +ＡＢＣ 白日依山尽， 2006 +「ノートを買った。」 diff --git a/utils/test-mongolian.txt b/utils/test-mongolian.txt new file mode 100644 index 00000000..9117b7b1 --- /dev/null +++ b/utils/test-mongolian.txt @@ -0,0 +1,15 @@ +ᠡᠷᠲᠡ ᠤᠷᠢᠳᠠ ᠺᠠᠪᠠᠯᠢᠺ ᠪᠠᠯᠭᠠᠰᠤᠨ ᠳᠤᠷ ᠪᠢᠷᠠᠮᠠᠨ ᠤ ᠬᠠᠮᠤᠭ ᠤᠬᠠᠭᠠᠨ ᠤ ᠵᠦᠢᠯ ᠳᠦᠷ ᠮᠡᠷᠭᠡᠨ ᠪᠣᠯᠤᠭᠰᠠᠨ ᠰᠠᠢᠨ ᠲᠥᠷᠥᠯ ᠲᠦ ᠬᠡᠮᠡᠬᠦ +ᠨᠢᠭᠡᠨ ᠪᠢᠷᠠᠮᠠᠨ ᠪᠦᠯᠦᠭᠡ᠃ ᠲᠡᠷᠡ ᠪᠢᠷᠠᠮᠠᠨ ᠳᠤᠷ ᠰᠡᠳᠬᠢᠯ ᠳᠤᠷ ᠲᠠᠭᠠᠯᠠᠬᠤ ᠨᠡᠷᠡᠲᠦ ᠨᠢᠭᠡᠨ ᠬᠠᠲᠤᠭᠲᠠᠢ ᠪᠦᠯᠦᠭᠡ᠃ ᠲᠡᠷᠡ ᠬᠣᠶᠠᠷ  +ᠠᠴᠠ ᠨᠢᠭᠡᠨ ᠬᠥᠪᠡᠭᠦᠨ ᠲᠥᠷᠥᠵᠦᠬᠦᠢ᠃ ᠲᠡᠷᠡ ᠬᠥᠪᠡᠭᠦᠨ ᠢᠨᠤ ᠦᠴᠦᠭᠦᠬᠡᠨ ᠡᠴᠡ ᠭᠡᠭᠡᠨ ᠣᠶᠤᠲᠤ ᠶᠡᠬᠡᠰ ᠦᠨ ᠶᠠᠪᠤᠳᠠᠯ ᠢᠶᠠᠷ ᠶᠠᠪᠤᠭᠴᠢ +ᠨᠢᠭᠡᠨ ᠪᠣᠯᠪᠠᠢ᠃ ᠲᠡᠨᠳᠡ ᠡᠬᠡ ᠢᠨᠤ ᠠᠶ᠎ᠠ ᠡᠨᠡ ᠬᠥᠪᠡᠭᠦᠨ ᠲᠥᠷᠥᠭᠡᠳ ᠰᠠᠴᠠ ᠶᠡᠬᠡᠰ ᠦᠨ ᠶᠠᠪᠤᠳᠠᠯ ᠢᠶᠠᠷ ᠶᠠᠪᠤᠭᠴᠢ ᠭᠡᠭᠡᠨ ᠣᠶᠤᠲᠤ +ᠪᠦᠬᠦ ᠶᠢᠨ ᠲᠤᠯᠠ᠃ ᠮᠠᠭᠠᠳ ᠨᠢᠭᠡᠨ ᠵᠠᠶᠠᠭ᠋᠎ᠠ ᠲᠤ ᠪᠤᠢ ᠵ᠎ᠠ ᠬᠡᠮᠡᠵᠦ᠃ ᠭᠡᠢᠭᠰᠡᠨ ᠬᠡᠮᠡᠨ ᠨᠡᠷ᠎ᠡ ᠥᠭᠭᠦᠭᠡᠳ᠃ ᠠᠢ ᠡᠨᠡ ᠬᠥᠪᠡᠭᠦᠨ  +ᠳ᠋ᠦᠷ ᠬᠠᠮᠤᠭ ᠤᠬᠠᠭᠠᠨ ᠤ ᠵᠦᠢᠯ ᠢ ᠰᠤᠷᠭᠠᠰᠤᠭᠠᠢ ᠬᠡᠮᠡᠵᠦ ᠪᠦᠷᠦᠨ᠃ ᠡᠴᠢᠭᠡ ᠡᠬᠡ ᠬᠣᠶᠠᠷ ᠪᠡᠷ ᠰᠤᠷᠭᠠᠭᠰᠠᠨ ᠳᠤᠷ᠃ ᠳᠥᠷᠪᠡᠯ +ᠦᠭᠡᠢ ᠮᠡᠳᠡᠬᠦᠢ ᠨᠢᠭᠡᠨ ᠪᠣᠯᠪᠠᠢ᠃ ᠲᠡᠷᠡ ᠬᠥᠪᠡᠭᠦᠨ ᠢᠨᠤ ᠳᠣᠯᠣᠭᠠᠨ ᠵᠢᠯ ᠪᠣᠯᠤᠭᠰᠠᠨ ᠳᠤᠷ᠃ ᠪᠢᠷᠠᠮᠠᠨ ᠤ ᠤᠬᠠᠭᠠᠨ ᠤ ᠵᠦᠢᠯ ᠳᠦᠷ +ᠮᠡᠷᠭᠡᠨ ᠪᠣᠯᠤᠭᠰᠠᠨ ᠡᠷᠳᠡᠮ ᠦᠳ ᠢᠨᠤ ᠬᠠᠮᠤᠭ ᠪᠦᠭᠦᠳᠡᠭᠡᠷ ᠲᠦᠷ ᠰᠣᠨᠣᠰᠲᠠᠭᠰᠠᠨ᠋᠎ᠠ᠃ ᠲᠡᠷᠡ ᠴᠠᠭ ᠲᠤᠷ ᠺᠠᠪᠠᠯᠢᠺ ᠪᠠᠯᠭᠠᠰᠤᠨ ᠳᠠᠬᠢᠨ ᠤᠬᠠᠭᠠᠨ ᠤ +ᠵᠦᠢᠯ ᠳᠦᠷ ᠮᠡᠷᠭᠡᠨ ᠪᠣᠯᠤᠭᠰᠠᠨ ᠬᠠᠮᠤᠭ ᠪᠢᠷᠠᠮᠠᠨ ᠴᠢᠭᠤᠯᠵᠤ ᠤᠬᠠᠭᠠᠨ ᠤ ᠵᠦᠢᠯ ᠳᠦᠷ ᠲᠡᠮᠡᠴᠡᠭᠰᠡᠨ ᠳᠦᠷ᠃ ᠪᠢᠷᠠᠮᠠᠨ ᠤ ᠭᠡᠢᠭᠰᠡᠨ ᠬᠥᠪᠡᠭᠦᠨ +ᠮᠠᠱᠢ ᠶᠡᠬᠡ ᠦᠯᠡᠮᠵᠢ ᠪᠣᠯᠤᠭᠰᠠᠨ ᠳᠤᠷ᠃ ᠲᠡᠳᠡᠭᠡᠷ ᠪᠢᠷᠠᠮᠠᠨ ᠥᠭᠦᠯᠡᠷ ᠦᠨ᠃ ᠠᠢ ᠬᠥᠪᠡᠭᠦᠨ ᠠ᠋ ᠨᠠᠰᠤᠨ ᠴᠢᠨᠤ ᠡᠢᠮᠦ ᠵᠠᠯᠠᠭᠤ +ᠪᠥᠭᠡᠲᠡᠯ᠎ᠡ᠃ ᠤᠬᠠᠭᠠᠨ ᠤ ᠵᠦᠢᠯ ᠳᠦᠷ ᠡᠨᠡ ᠮᠡᠲᠦ ᠮᠡᠷᠭᠡᠨ ᠪᠣᠯᠤᠭᠰᠠᠨ ᠬᠡᠷ ᠪᠤᠶᠤ ᠬᠡᠮᠡᠨ ᠠᠰᠠᠭᠪᠠᠰᠤ᠃ ᠬᠥᠪᠡᠭᠦᠨ ᠥᠭᠦᠯᠡᠷ ᠦᠨ᠃ +ᠲᠣᠭᠣᠯᠤᠭᠰᠠᠨ ᠪᠤᠷᠬᠠᠨ ᠪᠡᠷ ᠪᠠᠭᠱᠢ ᠮᠢᠨᠤ ᠪᠤᠢ᠃ ᠪᠣᠭᠳᠠᠰ ᠤᠨ ᠨᠣᠮ ᠪᠡᠷ ᠢᠪᠡᠭᠡᠭᠴᠢ ᠮᠢᠨᠤ ᠪᠤᠢ᠃ ᠪᠤᠷᠰᠠᠩ ᠬᠤᠸᠠᠷᠠᠭ ᠤᠳ ᠪᠡᠷ +ᠤᠳᠤᠷᠢᠳᠳᠤᠭᠴᠢ ᠮᠢᠨᠤ ᠪᠤᠢ᠃ ᠭᠤᠷᠪᠠᠨ ᠡᠷᠳᠡᠨᠢᠰ ᠦᠨ ᠠᠳᠢᠰᠲᠢᠳ ᠬᠢᠭᠰᠡᠨ ᠦ ᠬᠦᠴᠦ ᠪᠡᠷ ᠦᠢᠯᠡ ᠦᠷᠡᠰ ᠲᠦᠷ ᠦᠨᠡᠮᠱᠢᠭᠰᠡᠨ ᠦ ᠲᠤᠯᠠ᠃ +ᠰᠡᠱᠢᠭ ᠦᠭᠡᠢ ᠡᠷᠲᠡ ᠱᠢᠯᠲᠠᠭᠠᠨ ᠤ ᠬᠥᠷᠥᠩᠭᠡ ᠰᠠᠴᠤᠭᠰᠠᠨ ᠳᠤᠷ᠃ ᠦᠷ᠎ᠡ ᠦᠯᠦ ᠬᠣᠮᠰᠠᠳᠬᠤ ᠪᠤᠶᠠᠨ ᠢ ᠬᠢᠴᠢᠶᠡᠭᠰᠡᠨ ᠪᠤᠢ᠃ ᠨᠠᠰᠤᠨ +ᠮᠢᠨᠤ ᠵᠠᠯᠠᠭᠤ ᠪᠣᠯᠪᠠᠰᠤ᠃ ᠤᠬᠠᠭᠠᠨ ᠤ ᠵᠦᠢᠯ ᠳᠦᠷ ᠮᠡᠷᠭᠡᠨ ᠪᠣᠯᠤᠭᠰᠠᠨ ᠤ ᠤᠴᠢᠷ ᠲᠡᠢᠮᠦ ᠪᠤᠢ ᠅ ᠅ diff --git a/utils/test-nko.txt b/utils/test-nko.txt new file mode 100644 index 00000000..65a4347e --- /dev/null +++ b/utils/test-nko.txt @@ -0,0 +1,15 @@ +ߝߘߊ߬ߝߌ߲߬ߠߊ߫ ߟߊ߬ߘߏ߲߬ߞߏ߬ߦߊ߬ߟߌ ߜߙߋ߬ߡߊ߬ߕߍ߰ߟߌ +ߞߖ߭ߊߓߎߟߊ߲ߞߊ ߓߍ߲߬ߡߊ߬ߞߊ߲ ߠߎ߬ : + +ߝߘߊ߬ߝߌ߲߬ߠߊ߫ ߘߎ߰ߙߋ߲ ߠߎ߬ ߟߊ߫ ߢߐ߲߯ߓߍ߲ ߟߊ߬ߘߏ߲߬ߞߏ߬ߦߊ߬ߟߌ ߞߊߡߊ߬ ߞߖ߭ߊߓߎߟߊߟߊ߲ߞߊ߫߸ ( ߞߊ߬ߓߌߛߊ߬ ) ߣߌ߫ ( ߓߌ߬ߛ߭ߊ߯ߙߊ ) ߘߍ߬ߘߊ ߟߎ߬ ߟߊ߫ ߓߊ߯ߙߊ߫ +ߘߊߞߎ߲ ߡߌ߬ߘߊ߬ ߞߣߍ ߞߊ߲߬߸ (IDRC = ߞߣߊߘߊ߫ ߝߘߏ߬ߓߊ߬ ߡߣߊ߬ߙߏ߲߬ߠߌ߲ ߝߊ߲ߓߊ ߞ.ߝ.ߡ.ߝ.) ߞߊ߬ ߡߍ߲ ߖߐ߰ߣߍ ߓߐ߫ ߸ (MTDS = +ߡߊ߬ߙߐߞߎ߫ ߖߊ߬ߥߏ ߟߊ߬ߥߙߎ߬ߞߌ߬ߟߌ ߗߋߢߊߟߌ ߡ.ߖ.ߥߗ.) ߝߊ߬ߙߊ ߘߐ߫ ߊ߬ ߞߊ߲߬ ( ߞߖ߭ߊߓߎߟߊ߲ߞߊ߫ ߕߎߞߑߣߏߔߊߞ ) ߘߍ߬ߞߙߎ ߝߊ߲ߓߊ ߝߍ߬. + +ߞߎ߲߬ߜߙߊ ߣߌ߲߬ ߞߊ߬ ߕߣߐ߬ߓߊ߫ ߛߐ߬ߘߐ߲߬ ߡߊߙߐߞߎ߬ ߖߡߊ߬ߣߊ ߡߊ߬ߞߐ߬ߙߐ߲߬ߞߐ߬ߙߐ߲߬ߠߌ ߞߏߕߌ߮ ߣߴߊ߬ ߣߐ߬ߝߍ߬ ߖߡߊ ߟߊ߫ ߸ ߏ߬ ߟߎ߬ ߡߍ߲ ߠߎ߫ ߣߊ߬ ߘߊ߫ +ߞߏߕߌ߯ ߟߎ߬ ߞߊ߲ߕߌ߮ ߞߐߦߌ߬ߘߊ߬، ߞߊ߬ ߕߐ߬ߣߐ߫ ߛߐ߬ߘߐ߲߬ ߞߣߊߘߊ߫ ߟߊ߬ߛߌ߰ߘߋ߲ ߝߣߊ߫ ߟߊ߫ ߣߊ߬ߟߌ ߣߌ߫ ߜߙߋ߫ ߜߘߍ ߘߎ߰ߙߋ߲߫ ߣߊ߬ߓߊ߮ ߟߎ߬ ߟߊ߫. + +ߕߋ߬ߟߋ߫ ߛߓߊ߬ ߖߊ߬ߣߍ߲߬ ߓߊ߯ߙߊ ߘߝߊߣߍ߲ ߞߐ߫ ߸ ߞߎ߲߬ߜߙߊ ߕߘߍ߬ߒ߬ߘߐ߬ߓߊ߰ߕߐ ߟߎ߫ ߓߍ߲߬ ߘߊ߫ ߞߊ߲߫ ߣߊ߬ߕߐ ߢߌ߲߬ ߠߎ߫ ߡߊ߬ : + +• ߕߟߋ߬ߓߊ߮ ߛߋߒߞߏߟߦߊ ߣߌ߫ ߟߐ߲ߕߊ ( ߕ.ߛ.ߟ.

To the greatest extent permitted by, but not in contravention of, + applicable law, Affirmer hereby overtly, fully, permanently, irrevocably and + unconditionally waives, abandons, and surrenders all of Affirmer's Copyright + and Related Rights and associated claims and causes of action, whether now + known or unknown (including existing as well as future claims and causes of + action), in the Work (i) in all territories worldwide, (ii) for the maximum + duration provided by applicable law or treaty (including future time extensions), + (iii) in any current or future medium and for any number of copies, and (iv) + for any purpose whatsoever, including without limitation commercial, advertising + or promotional purposes (the "Waiver").

The License shall be deemed effective as of the date CC0 + was applied by Affirmer to the Work. Should any part of the License for any + reason be judged legally invalid or ineffective under applicable law, such + partial invalidity or ineffectiveness shall not invalidate the remainder of + the License, and in such case Affirmer hereby affirms that he or she will + not (i) exercise any of his or her remaining Copyright and Related Rights + in the Work or (ii) assert any associated claims and causes of action with + respect to the Work, in either case contrary to Affirmer's express Statement + of Purpose. + . + 4.

"Collection" means a collection of literary or artistic works, such as + encyclopedias and anthologies, or performances, phonograms or + broadcasts, or other works or subject matter other than works listed + in Section 1(f) below, which, by reason of the selection and + arrangement of their contents, constitute intellectual creations, in + which the Work is included in its entirety in unmodified form along + with one or more other contributions, each constituting separate and + independent works in themselves, which together are assembled into a + collective whole.

"Creative Commons Compatible License" means a license that is listed + at https://creativecommons.org/compatiblelicenses that has been + approved by Creative Commons as being essentially equivalent to this + License, including, at a minimum, because that license: (i) contains + terms that have the same purpose, meaning and effect as the License + Elements of this License; and, (ii) explicitly permits the relicensing + of adaptations of works made available under that license under this + License or a Creative Commons jurisdiction license with the same + License Elements as this License. + d.

"Publicly Perform" means to perform public recitations of the Work and + to communicate to the public those public recitations, by any means or + process, including by wire or wireless means or public digital + performances; to make available to the public Works in such a way that + members of the public may access these Works from a place and at a + place individually chosen by them; to perform the Work to the public + by any means or process and the communication to the public of the + performances of the Work, including by public digital performance; to + broadcast and rebroadcast the Work by any means including signs, + sounds or images. + k. "Reproduce" means to make copies of the Work by any means including + without limitation by sound or visual recordings and the right of + fixation and reproducing fixations of the Work, including storage of a + protected performance or phonogram in digital form or other electronic + medium. + . + 2.

License Grant. Subject to the terms and conditions of this License, + Licensor hereby grants You a worldwide, royalty-free, non-exclusive, + perpetual (for the duration of the applicable copyright) license to + exercise the rights in the Work as stated below: + . + a. to Reproduce the Work, to incorporate the Work into one or more + Collections, and to Reproduce the Work as incorporated in the + Collections; + b. to create and Reproduce Adaptations provided that any such Adaptation, + including any translation in any medium, takes reasonable steps to + clearly label, demarcate or otherwise identify that changes were made + to the original Work. For example, a translation could be marked "The + original work was translated from English to Spanish," or a + modification could indicate "The original work has been modified."; + c. to Distribute and Publicly Perform the Work including as incorporated + in Collections; and, + d. to Distribute and Publicly Perform Adaptations. + e. For the avoidance of doubt: + . + i. Non-waivable Compulsory License Schemes. In those jurisdictions in + which the right to collect royalties through any statutory or + compulsory licensing scheme cannot be waived, the Licensor + reserves the exclusive right to collect such royalties for any + exercise by You of the rights granted under this License; + ii. Waivable Compulsory License Schemes. In those jurisdictions in + which the right to collect royalties through any statutory or + compulsory licensing scheme can be waived, the Licensor waives the + exclusive right to collect such royalties for any exercise by You + of the rights granted under this License; and, + iii. Voluntary License Schemes. The Licensor waives the right to + collect royalties, whether individually or, in the event that the + Licensor is a member of a collecting society that administers + voluntary licensing schemes, via that society, from any exercise + by You of the rights granted under this License. + . + The above rights may be exercised in all media and formats whether now + known or hereafter devised. The above rights include the right to make + such modifications as are technically necessary to exercise the rights in + other media and formats. Subject to Section 8(f), all rights not expressly + granted by Licensor are hereby reserved. + . + 4. Restrictions. The license granted in Section 3 above is expressly made + subject to and limited by the following restrictions: + . + a. You may Distribute or Publicly Perform the Work only under the terms + of this License. You must include a copy of, or the Uniform Resource + Identifier (URI) for, this License with every copy of the Work You + Distribute or Publicly Perform. You may not offer or impose any terms + on the Work that restrict the terms of this License or the ability of + the recipient of the Work to exercise the rights granted to that + recipient under the terms of the License. You may not sublicense the + Work. You must keep intact all notices that refer to this License and + to the disclaimer of warranties with every copy of the Work You + Distribute or Publicly Perform. When You Distribute or Publicly + Perform the Work, You may not impose any effective technological + measures on the Work that restrict the ability of a recipient of the + Work from You to exercise the rights granted to that recipient under + the terms of the License. This Section 4(a) applies to the Work as + incorporated in a Collection, but this does not require the Collection + apart from the Work itself to be made subject to the terms of this + License. If You create a Collection, upon notice from any Licensor You + must, to the extent practicable, remove from the Collection any credit + as required by Section 4(c), as requested. If You create an + Adaptation, upon notice from any Licensor You must, to the extent + practicable, remove from the Adaptation any credit as required by + Section 4(c), as requested. + b. You may Distribute or Publicly Perform an Adaptation only under the + terms of: (i) this License; (ii) a later version of this License with + the same License Elements as this License; (iii) a Creative Commons + jurisdiction license (either this or a later license version) that + contains the same License Elements as this License (e.g., + Attribution-ShareAlike 3.0 US)); (iv) a Creative Commons Compatible + License. If you license the Adaptation under one of the licenses + mentioned in (iv), you must comply with the terms of that license. If + you license the Adaptation under the terms of any of the licenses + mentioned in (i), (ii) or (iii) (the "Applicable License"), you must + comply with the terms of the Applicable License generally and the + following provisions: (I) You must include a copy of, or the URI for, + the Applicable License with every copy of each Adaptation You + Distribute or Publicly Perform; (II) You may not offer or impose any + terms on the Adaptation that restrict the terms of the Applicable + License or the ability of the recipient of the Adaptation to exercise + the rights granted to that recipient under the terms of the Applicable + License; (III) You must keep intact all notices that refer to the + Applicable License and to the disclaimer of warranties with every copy + of the Work as included in the Adaptation You Distribute or Publicly + Perform; (IV) when You Distribute or Publicly Perform the Adaptation, + You may not impose any effective technological measures on the + Adaptation that restrict the ability of a recipient of the Adaptation + from You to exercise the rights granted to that recipient under the + terms of the Applicable License. This Section 4(b) applies to the + Adaptation as incorporated in a Collection, but this does not require + the Collection apart from the Adaptation itself to be made subject to + the terms of the Applicable License. + c. If You Distribute, or Publicly Perform the Work or any Adaptations or + Collections, You must, unless a request has been made pursuant to + Section 4(a), keep intact all copyright notices for the Work and + provide, reasonable to the medium or means You are utilizing: (i) the + name of the Original Author (or pseudonym, if applicable) if supplied, + and/or if the Original Author and/or Licensor designate another party + or parties (e.g., a sponsor institute, publishing entity, journal) for + attribution ("Attribution Parties") in Licensor's copyright notice, + terms of service or by other reasonable means, the name of such party + or parties; (ii) the title of the Work if supplied; (iii) to the + extent reasonably practicable, the URI, if any, that Licensor + specifies to be associated with the Work, unless such URI does not + refer to the copyright notice or licensing information for the Work; + and (iv) , consistent with Ssection 3(b), in the case of an + Adaptation, a credit identifying the use of the Work in the Adaptation + (e.g., "French translation of the Work by Original Author," or + "Screenplay based on original Work by Original Author"). The credit + required by this Section 4(c) may be implemented in any reasonable + manner; provided, however, that in the case of a Adaptation or + Collection, at a minimum such credit will appear, if a credit for all + contributing authors of the Adaptation or Collection appears, then as + part of these credits and in a manner at least as prominent as the + credits for the other contributing authors. For the avoidance of + doubt, You may only use the credit required by this Section for the + purpose of attribution in the manner set out above and, by exercising + Your rights under this License, You may not implicitly or explicitly + assert or imply any connection with, sponsorship or endorsement by the + Original Author, Licensor and/or Attribution Parties, as appropriate, + of You or Your use of the Work, without the separate, express prior + written permission of the Original Author, Licensor and/or Attribution + Parties. + d. Except as otherwise agreed in writing by the Licensor or as may be + otherwise permitted by applicable law, if You Reproduce, Distribute or + Publicly Perform the Work either by itself or as part of any + Adaptations or Collections, You must not distort, mutilate, modify or + take other derogatory action in relation to the Work which would be + prejudicial to the Original Author's honor or reputation. Licensor + agrees that in those jurisdictions (e.g. Japan), in which any exercise + of the right granted in Section 3(b) of this License (the right to + make Adaptations) would be deemed to be a distortion, mutilation, + modification or other derogatory action prejudicial to the Original + Author's honor and reputation, the Licensor will waive or not assert, + as appropriate, this Section, to the fullest extent permitted by the + applicable national law, to enable You to reasonably exercise Your + right under Section 3(b) of this License (right to make Adaptations) + but not otherwise. + . + 5. Representations, Warranties and Disclaimer + . + UNLESS OTHERWISE MUTUALLY AGREED TO BY THE PARTIES IN WRITING, LICENSOR + OFFERS THE WORK AS-IS AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY + KIND CONCERNING THE WORK, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE, + INCLUDING, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTIBILITY, + FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT, OR THE ABSENCE OF + LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OF ABSENCE OF ERRORS, + WHETHER OR NOT DISCOVERABLE. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION + OF IMPLIED WARRANTIES, SO SUCH EXCLUSION MAY NOT APPLY TO YOU. + . + 6. Limitation on Liability. EXCEPT TO THE EXTENT REQUIRED BY APPLICABLE + LAW, IN NO EVENT WILL LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY FOR + ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES + ARISING OUT OF THIS LICENSE OR THE USE OF THE WORK, EVEN IF LICENSOR HAS + BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. + . + 7. Termination + . + a. This License and the rights granted hereunder will terminate + automatically upon any breach by You of the terms of this License. + Individuals or entities who have received Adaptations or Collections + from You under this License, however, will not have their licenses + terminated provided such individuals or entities remain in full + compliance with those licenses. Sections 1, 2, 5, 6, 7, and 8 will + survive any termination of this License. + b. Subject to the above terms and conditions, the license granted here is + perpetual (for the duration of the applicable copyright in the Work). + Notwithstanding the above, Licensor reserves the right to release the + Work under different license terms or to stop distributing the Work at + any time; provided, however that any such election will not serve to + withdraw this License (or any other license that has been, or is + required to be, granted under the terms of this License), and this + License will continue in full force and effect unless terminated as + stated above. + . + 8. Miscellaneous + . + a. Each time You Distribute or Publicly Perform the Work or a Collection, + the Licensor offers to the recipient a license to the Work on the same + terms and conditions as the license granted to You under this License. + b. Each time You Distribute or Publicly Perform an Adaptation, Licensor + offers to the recipient a license to the original Work on the same + terms and conditions as the license granted to You under this License. + c. If any provision of this License is invalid or unenforceable under + applicable law, it shall not affect the validity or enforceability of + the remainder of the terms of this License, and without further action + by the parties to this agreement, such provision shall be reformed to + the minimum extent necessary to make such provision valid and + enforceable. + d. No term or provision of this License shall be deemed waived and no + breach consented to unless such waiver or consent shall be in writing + and signed by the party to be charged with such waiver or consent. + e. This License constitutes the entire agreement between the parties with + respect to the Work licensed here. There are no understandings, + agreements or representations with respect to the Work not specified + here. Licensor shall not be bound by any additional provisions that + may appear in any communication from You. This License may not be + modified without the mutual written agreement of the Licensor and You. + f. The rights granted under, and the subject matter referenced, in this + License were drafted utilizing the terminology of the Berne Convention + for the Protection of Literary and Artistic Works (as amended on + September 28, 1979), the Rome Convention of 1961, the WIPO Copyright + Treaty of 1996, the WIPO Performances and Phonograms Treaty of 1996 + and the Universal Copyright Convention (as revised on July 24, 1971). + These rights and subject matter take effect in the relevant + jurisdiction in which the License terms are sought to be enforced + according to the corresponding provisions of the implementation of + those treaty provisions in the applicable national law. If the + standard suite of rights granted under applicable copyright law + includes additional rights not granted under this License, such + additional rights are deemed to be included in the License; this + License is not intended to restrict the license of any rights under + applicable law. + . + . + Creative Commons Notice + . + Creative Commons is not a party to this License, and makes no warranty + whatsoever in connection with the Work.

Jul 2021 21:08:31 +0200 +Subject: font-desc: Use local volatile double values to store sizes + +Under i386 multiplying double and integer values and cast it to integer +may end up to compute the wrong value when only 387 FPU is used, because +the temporary value will be stored in a register whose precision isn't +good enough. +And so, some multiplications which are expected to produce an integer, +will actually return a truncated value, that will be eventually floored. + +An example is 1.2 * 12800 that is clearly 15360.0, but will produce +15359 when casted to int in the said i386 environment. + +So use a temporary double variable to ensure that we do this computation +in the double scope, before casting to int. + +And this will avoid using the said register, even when using more +aggressive optimizations (as per marking the local variable volatile). + +Fixes: https://gitlab.gnome.org/GNOME/pango/-/issues/580 + +Origin: https://gitlab.gnome.org/GNOME/pango/-/merge_requests/377

And so, some multiplications which are expected to produce an integer, will actually return a truncated value, that will be eventually floored. An example is 1.2 * 12800 that is clearly 15360.0, but will produce 15359 when casted to int in the said i386 environment. So use a temporary double variable to ensure that we do this computation in the double scope, before casting to int. And this will avoid using the said register, even when using more aggressive optimizations (as per marking the local variable volatile).
