As a derived work, anything +Luaotflaod adds to that is also subject to the same license at the same +version. The “any later version” clause as used by the FSF in the license text +*does not apply* to either Context or Luaotfload, despite being kept around in +the license text given below. + +------------------------------------------------------------------------------- + LICENSE TEXT BELOW +------------------------------------------------------------------------------- + + GNU GENERAL PUBLIC LICENSE + Version 2, June 1991 + + Copyright (C) 1989, 1991 Free Software Foundation, Inc., + 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA + Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Lesser General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + <one line to give the program's name and a brief idea of what it does.> + Copyright (C) <year> <name of author> + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License along + with this program; if not, write to the Free Software Foundation, Inc., + 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary.

A +lot of files are needed for one font (\abbrev{tfm}, \abbrev{pfb}, +\abbrev{map}, \abbrev{fd}, \abbrev{vf}), and due to the 8-Bit encoding +each font is limited to 256 characters. + +But the font world has evolved since the original \TEX, and new +typographic systems have appeared, most notably the so called +\emphasis{smart font} technologies like \OpenType fonts (\abbrev{otf}). + +These fonts can contain many more characters than \TEX fonts, as well +as additional functionality like ligatures, old-style numbers, small +capitals, etc., and support more complex writing systems like Arabic +and Indic\footnote{% + Unfortunately, \identifier{luaotfload} doesn‘t support many Indic + scripts right now. + Assistance in implementing the prerequisites is greatly + appreciated. +} +scripts. + +\OpenType fonts are widely deployed and available for all modern +operating systems. + +As of 2013 they have become the de facto standard for advanced text +layout. + +However, until recently the only way to use them directly in the \TEX +world was with the \XETEX engine. + +Unlike \XETEX, \LUATEX has no built-in support for \OpenType or +technologies other than the original \TEX fonts. + +Instead, it provides hooks for executing \LUA code during the \TEX run +that allow implementing extensions for loading fonts and manipulating +how input text is processed without modifying the underlying engine. + +This is where \identifier{luaotfload} comes into play: +Based on code from \CONTEXT, it extends \LUATEX with functionality necessary +for handling \OpenType fonts. + +Additionally, it provides means for accessing fonts known to the operating +system conveniently by indexing the metadata. + +\endsection + +%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +\beginsection {Thanks} +%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% + +\identifier{Luaotfload} is part of \LUALATEX, the community-driven +project to provide a foundation for using the \LATEX format with the +full capabilites of the \LUATEX engine. +% +As such, the distinction between end users, contributors, and project +maintainers is intentionally kept less strict, lest we unduly +personalize the common effort. + +Nevertheless, the current maintainers would like to express their +gratitude to Khaled Hosny, Akira Kakuto, Hironori Kitagawa and Dohyun +Kim. +% +Their contributions -- be it patches, advice, or systematic +testing -- made the switch from version 1.x to 2.2 possible. +% +Also, Hans Hagen, the author of the font loader, made porting the +code to \LATEX a breeze due to the extra effort he invested into +isolating it from the rest of \CONTEXT, not to mention his assistance +in the task and willingness to respond to our suggestions. + +\endsection + +%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +\beginsection {Loading Fonts} +%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% + +\identifier{luaotfload} supports an extended font request syntax: + +\beginnarrower + \nonproportional{\string\font\string\foo\space= \string{}% + \meta{prefix}\nonproportional{:}% + \meta{font name}\nonproportional{:}% + \meta{font features}\nonproportional{\string}}% + \meta{\TEX font features} +\endnarrower + +\noindent +The curly brackets are optional and escape the spaces in the enclosed +font name. +% +Alternatively, double quotes serve the same purpose. +% +A selection of individual parts of the syntax are discussed below; +for a more formal description see figure \ref{font-syntax}. + +\beginsyntaxfloat + {font-syntax} + {Font request syntax. + Braces or double quotes around the + \emphasis{specification} rule will + preserve whitespace in file names. + In addition to the font style modifiers + (\emphasis{slash-notation}) given above, there + are others that are recognized but will be silently + ignored: \nonproportional{aat}, + \nonproportional{icu}, and + \nonproportional{gr}. + The special terminals are: + \smallcaps {feature\textunderscore id} for a valid font + feature name and + \smallcaps {feature\textunderscore value} for the corresponding + value. + \smallcaps {tfmname} is the name of a \abbrev{tfm} file. + \smallcaps {digit} again refers to bytes

\identifier{luaotfload}{ }Way} + +In \identifier{luaotfload}, the canonical syntax for font requests +requires a \emphasis{prefix}: +% +\beginnarrower + \nonproportional{\string\font\string\fontname\space= }% + \meta{prefix}% + \nonproportional{:}% + \meta{fontname}% + \dots +\endnarrower +% +where \meta{prefix} is either \inlinecode{file:} or \inlinecode {name:}.\footnote{% + The development version also knows two further prefixes, + \inlinecode {kpse:} and \inlinecode {my:}. + % + A \inlinecode {kpse} lookup is restricted to files that can be found by + \identifier{kpathsea} and + will not attempt to locate system fonts. + % + This behavior can be of value when an extra degree of encapsulation is + needed, for instance when supplying a customized tex distribution. + + The \inlinecode {my} lookup takes this a step further: it lets you define + a custom resolver function and hook it into the \luafunction{resolve_font} + callback. + % + This ensures full control over how a file is located. + % + For a working example see the + \hyperlink [test repo]{https://bitbucket.org/phg/lua-la-tex-tests/src/5f6a535d/pln-lookup-callback-1.tex}. +} +% +It determines whether the font loader should interpret the request as +a \emphasis{file name} or + \emphasis{font name}, respectively, +which again influences how it will attempt to locate the font. +% +Examples for font names are + “Latin Modern Italic”, + “GFS Bodoni Rg”, and + “PT Serif Caption” +-- they are the human readable identifiers +usually listed in drop-down menus and the like.\footnote{% + Font names may appear like a great choice at first because they + offer seemingly more intuitive identifiers in comparison to arguably + cryptic file names: + % + “PT Sans Bold” is a lot more descriptive than \fileent{PTS75F.ttf}. + On the other hand, font names are quite arbitrary and there is no + universal method to determine their meaning. + % + While \identifier{luaotfload} provides fairly sophisticated heuristic + to figure out a matching font style, weight, and optical size, it + cannot be relied upon to work satisfactorily for all font files. + % + For an in-depth analysis of the situation and how broken font names + are, please refer to + \hyperlink [this post]{http://www.ntg.nl/pipermail/ntg-context/2013/073889.html} + by Hans Hagen, the author of the font loader. + % + If in doubt, use filenames. + % + \fileent{luaotfload-tool} can perform the matching for you with the + option \inlinecode {--find=<name>}, and you can use the file name it returns + in your font definition. +} +% +In order for fonts installed both in system locations and in your +\fileent{texmf} to be accessible by font name, \identifier{luaotfload} must +first collect the metadata included in the files. +% +Please refer to section~\ref{sec:fontdb} below for instructions on how to +create the database. + +File names are whatever your file system allows them to be, except +that that they may not contain the characters + \inlinecode {(}, + \inlinecode {:}, and + \inlinecode {/}. +% +As is obvious from the last exception, the \inlinecode {file:} lookup will +not process paths to the font location -- only those +files found when generating the database are addressable this way. +% +Continue below in the \XETEX section if you need to load your fonts +by path. +% +The file names corresponding to the example font names above are + \fileent{lmroman12-italic.otf}, + \fileent{GFSBodoni.otf}, and + \fileent{PTZ56F.ttf}. + +\endsubsection + +\beginsubsection {Compatibility Layer} + +In addition to the regular prefixed requests, \identifier{luaotfload} +accepts loading fonts the \XETEX way. +% +There are again two modes: bracketed and unbracketed. +A bracketed request looks as follows. + +\beginnarrower + \nonproportional{\string\font\string\fontname\space = [}% + \meta{/path/to/file}% + \nonproportional{]} +\endnarrower + +\noindent +Inside the square brackets, every character except for a closing

\& al.) functionality of + Context, see the file \fileent{typo-krn.lua} there. + % + The main difference is that \identifier{luaotfload} does not + use \LUATEX attributes to assign letterspacing to regions, + but defines virtual letterspaced versions of a font. + + The option \identifier{kernfactor} accepts a numeric value that + determines the letterspacing factor to be applied to the font + size. + % + E.~g. a kern factor of $0.42$ applied to a $10$ pt font + results in $4.2$ pt of additional kerning applied to each + pair of glyphs. + % + Ligatures are split into their component glyphs unless + explicitly ignored (see below). + + For compatibility with \XETEX an alternative + \identifier{letterspace} option is supplied that interprets the + supplied value as a \emphasis{percentage}

+\endsection + +%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +\beginsection {Auxiliary Functions} +%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% + +With release version 2.2, \identifier{luaotfload} received +additional functions for package authors to call from outside +(see the file \fileent{luaotfload-auxiliary.lua} for details). +% +The purpose of this addition twofold. +% +Firstly, \identifier{luaotfload} failed to provide a stable interface +to internals in the past which resulted in an unmanageable situation +of different packages abusing the raw access to font objects by means +of the \luafunction{patch_font} callback. +% +When the structure of the font object changed due to an update, all +of these imploded and several packages had to be fixed while +simultaneously providing fallbacks for earlier versions. +% +Now the patching is done on the \identifier{luaotfload} side and can +be adapted with future modifications to font objects without touching +the packages that depend on it. +% +Second, some the capabilities of the font loader and the names +database are not immediately relevant in \identifier{luaotfload} +itself but might nevertheless be of great value to package authors or +end users. + +Note that the current interface is not yet set in stone and the +development team is open to suggestions for improvements or +additions. + +\beginsubsection {Callback Functions} + +The \luafunction{patch_font} callback is inserted in the wrapper +\identifier{luaotfload} provides for the font definition callback +(see below, page \pageref{define-font}). +% +At this place it allows manipulating the font object immediately after +the font loader is done creating it. +% +For a short demonstration of its usefulness, here is a snippet that +writes an entire font object to the file \fileent{fontdump.lua}: + +\beginlisting + \input luaotfload.sty + \directlua{ + local dumpfile = "fontdump.lua" + local dump_font = function (tfmdata) + local data = table.serialize(tfmdata) + io.savedata(dumpfile, data) + end + + luatexbase.add_to_callback( + "luaotfload.patch_font", + dump_font, + "my_private_callbacks.dump_font" + ) + } + \font \dumpme = name:Iwona + \bye +\endlisting + +\emphasis{Beware}: this creates a Lua file of around 150,000 lines of +code, taking up 3~\abbrev{mb} of disk space. +% +By inspecting the output you can get a first impression of how a font +is structured in \LUATEX’s memory, what elements it is composed of, +and in what ways it can be rearranged. + +\beginsubsubsection {Compatibility with Earlier Versions} + +As has been touched on in the preface to this section, the structure +of the object as returned by the fontloader underwent rather drastic +changes during different stages of its development, and not all +packages that made use of font patching have kept up with every one +of it. +% +To ensure compatibility with these as well as older versions of +some packages, \identifier{luaotfload} sets up copies of or references +to data in the font table where it used to be located. +% +For instance, important parameters like the requested point size, the +units factor, and the font name have again been made accessible from +the toplevel of the table even though they were migrated to different +subtables in the meantime. + +\endsubsubsection + +\beginsubsubsection{Patches} + +These are mostly concerned with establishing compatibility with \XETEX. + +\beginfunctionlist + + \beginaltitem {set_sscale_dimens} + Calculate \texmacro{fontdimen}s 10 and 11 to emulate \XETEX. + \endaltitem + + \beginaltitem {set_capheight} + Calculates \texmacro{fontdimen} 8 like \XETEX. + \endaltitem + + \beginaltitem {patch_cambria_domh} + Correct some values of the font \emphasis{Cambria Math}. + \endaltitem + +\endfunctionlist + +\endsubsection + +\beginsubsection {Package Author’s Interface} + +As \LUATEX release 1.0 is nearing, the demand for a reliable interface +for package authors increases. + +\endsubsubsection + +\beginsubsubsection{Font Properties} + +Below functions mostly concern querying the different components of a +font like for instance the glyphs it contains, or what font features +are defined for which scripts. + +\beginfunctionlist + + \beginaltitem {aux.font_has_glyph (id : int, index : int)} + Predicate that returns true if the font \luafunction{id} + has glyph \luafunction{index}. + \endaltitem + + \beginaltitem {aux.slot_of_name(name : string)} + Translates an Adobe Glyph name to the corresponding glyph + slot. + \endaltitem + + \beginaltitem {aux.name_of_slot(slot : int)} + The inverse of \luafunction{slot_of_name}; note that this + might be incomplete as multiple glyph names may map to the + same codepoint, only one of which is returned by + \luafunction{name_of_slot}. + \endaltitem + + \beginaltitem {aux.provides_script(id : int, script : string)} + Test if a font supports \luafunction{script}. + \endaltitem + + \beginaltitem {aux.provides_language(id : int, script : string, language : string)} + Test if a font defines \luafunction{language} for a given + \luafunction{script}. + \endaltitem + + \beginaltitem {aux.provides_feature(id : int, script : string, + language : string, feature : string)} + Test if a font defines \luafunction{feature} for + \luafunction{language} for a given \luafunction{script}. + \endaltitem + + \beginaltitem {aux.get_math_dimension(id : int, dimension : string)} + Get the dimension \luafunction{dimension} of font \luafunction{id}. + \endaltitem + + \beginaltitem {aux.sprint_math_dimension(id : int, dimension : string)} + Same as \luafunction{get_math_dimension()}, but output the value + in scaled points at the \TEX end. + \endaltitem + +\endfunctionlist + +\endsubsubsection + +\beginsubsubsection{Database} + +%% not implemented, may come back later +\beginfunctionlist +% \beginaltitem {aux.scan_external_dir(dir : string)} +% Include fonts in directory \luafunction{dir} in font lookups without +% adding them to the database. +% + \beginaltitem {aux.read_font_index (void)} + Read the index file from the appropriate location (usually + the bytecode file \fileent{luaotfload-names.luc} somewhere + in the \fileent{texmf-var} tree) and return the result as a + table. The file is processed with each call so it is up to + the user to store the result for later access. + \endaltitem + + \beginaltitem {aux.font_index (void)} + Return a reference of the font names table used internally + by \identifier{luaotfload}. The index will be read if it + has not been loaded up to this point. Also a font scan that + overwrites the current index file might be triggered. Since + the return value points to the actual index, any + modifications to the table might influence runtime behavior + of \identifier{luaotfload}. + \endaltitem + +\endfunctionlist + +\endsubsubsection + +\endsubsection +\endsection + +%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +\beginsection {Troubleshooting} +%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% + +\beginsubsection {Database Generation} + +If you encounter problems with some fonts, please first update to the +latest version of this package before reporting a bug, as +\identifier{luaotfload} is under active development and still a moving +target. +% +The development takes place on \identifier{github} at +\hyperlink {https://github.com/lualatex/luaotfload} where there is an issue +tracker for submitting bug reports, feature requests and the likes. + +Bug reports are more likely to be addressed if they contain the output +of + +\beginlisting + luaotfload-tool --diagnose=environment,files,permissions +\endlisting + +\noindent Consult the man page for a description of these options. + +Errors during database generation can be traced by increasing the +verbosity level and redirecting log output to \fileent{stdout}: + +\beginlisting + luaotfload-tool -fuvvv --log=stdout +\endlisting + +\noindent or to a file in \fileent{/tmp}: + +\beginlisting + luaotfload-tool -fuvvv --log=file +\endlisting + +\noindent In the latter case, invoke the \inlinecode {tail(1)} utility on the +file for live monitoring of the progress. + +If database generation fails, the font last printed to the terminal or +log file is likely to be the culprit. +% +Please specify it when reporting a bug, and blacklist it for the time +being (see above, page \pageref{font-blacklist}). + +\endsubsection + +\beginsubsection {Font Features} + +A common problem is the lack of features for some +\OpenType fonts even when specified. +% +This can be related to the fact that some fonts do not provide features +for the \inlinecode {dflt} script (see above on page \pageref{script-tag}), +which is the default one in this package. +% +If this happens, assigning a noth script when the font is defined should +fix it. +% +For example with \inlinecode {latn}: + +\beginlisting + \font \test = file:MyFont.otf:script=latn;+liga; +\endlisting + +You can get a list of features that a font defines for scripts and +languages by querying it in \fileent{luaotfload-tool}: + +\beginlisting + luaotfload-tool --find="Iwona" --inspect +\endlisting + +\endsubsection + +\beginsubsection {\LUATEX Programming} + +Another strategy that helps avoiding problems is to not access raw +\LUATEX internals directly. +% +Some of them, even though they are dangerous to access, have not been +overridden or disabled. +% +Thus, whenever possible prefer the functions in the \luafunction{aux} +namespace over direct manipulation of font objects. For example, raw +access to the \luafunction{font.fonts} table like: + +\beginlisting + local somefont = font.fonts[2] +\endlisting + +\noindent can render already defined fonts unusable. +% +Instead, the function \luafunction{font.getfont()} should be used +because it has been replaced by a safe variant. + +However, \luafunction{font.getfont()} only covers fonts handled by the +font loader, e.~g. \identifier{OpenType} and \identifier{TrueType} +fonts, but not \abbrev{tfm} or \abbrev{ofm}. +% +Should you absolutely require access to all fonts known to \LUATEX, +including the virtual and autogenerated ones, then you need to query +both \luafunction{font.getfont()} and \luafunction{font.fonts}. +% +In this case, best define you own accessor: + +\beginlisting + local unsafe_getfont = function (id) + local tfmdata = font.getfont (id) + if not tfmdata then + tfmdata = font.fonts[id] + end + return tfmdata + end + + --- use like getfont() + local somefont = unsafe_getfont (2) +\endlisting + +\endsubsection +\endsection + +\beginsection {License} + +\identifier {luaotfload} is licensed under the terms of the +\hyperlink [GNU General Public License version 2.0]% + {https://www.gnu.org/licenses/old-licenses/gpl-2.0.html}. +Following the underlying fontloader code \identifier {luaotfload} +recognizes only that exact version as its license. +The „any later version” clause of the original license text as +copyrighted by the \hyperlink [Free Software Foundation]{http://www.fsf.org/} +\emphasis {does not apply} to either \identifier {luaotfload} or the +code imported from \CONTEXT. + +The complete text of the license is given as a separate file \fileent +{COPYING} in the toplevel directory of the +\hyperlink [\fileent {Luaotfload} Git repository]{https://github.com/lualatex/luaotfload/blob/master/COPYING}. +Distributions probably package it as \fileent +{doc/luatex/luaotfload/COPYING} in the relevant \fileent {texmf} tree. + +\endsection + +\endinput + diff --git a/luaotfload-tool.rst b/doc/luaotfload-tool.rst index 08acb6c..4b1a934 100644 --- a/luaotfload-tool.rst +++ b/doc/luaotfload-tool.rst @@ -6,21 +6,22 @@ generate and query the Luaotfload font names database ----------------------------------------------------------------------- -:Date: 2014-05-18 -:Copyright: GPL v2.0 -:Version: 2.4-4 -:Manual section: 1 -:Manual group: text processing +:Date: 2014-03-30 +:Copyright: GPL v2.0 +:Version: 2.5 +:Manual section: 1 +:Manual group: text processing SYNOPSIS ======================================================================= -**luaotfload-tool** [ -bDfFiIlnpquvVhw ] +**luaotfload-tool** [ -bcDfFiIlLnpqRSuvVhw ] **luaotfload-tool** --update [ --force ] [ --quiet ] [ --verbose ] [ --prefer-texmf ] [ --dry-run ] [ --formats=[+|-]EXTENSIONS ] [ --no-compress ] [ --no-strip ] + [ --local ] [ --max-fonts=N ] **luaotfload-tool** --find=FONTNAME [ --fuzzy ] [ --info ] [ --inspect ] [ --no-reload ] @@ -31,6 +32,8 @@ SYNOPSIS **luaotfload-tool** --list=CRITERION[:VALUE] [ --fields=F1,F2,...,Fn ] +**luaotfload-tool** --bisect=DIRECTIVE + **luaotfload-tool** --help **luaotfload-tool** --version @@ -49,10 +52,6 @@ the *Luaotfload* package.

For a more +detailed description please refer to the section “CONFIGURATION FILE” +of **git-config**\(1). A brief list of rules is given below: + + * Blank lines and lines starting with a semicolon (``;``) are ignored. + + * A configuration file is partitioned into sections that are declared + by specifying the section title in brackets on a separate line: :: + + [some-section] + ... section content ... + + * Sections consist of one or more variable assignments of the form + ``variable-name = value`` E. g.:: + + [foo] + bar = baz + quux = xyzzy + ... + + * Section and variable names may contain only uppercase and lowercase + letters as well as dashes (``-``). + + +VARIABLES +======================================================================= + +Variables in belong into a configuration section and their values must +be of a certain type. Some of them have further constraints. For +example, the “color callback” must be a string of one of the values +``pre_linebreak_filter`` or ``pre_output_filter``, defined in the +section *run*. + +Currently, the configuration is organized into four sections: + +db + Options relating to the font index. + +misc + Options without a clearly defined category. + +paths + Path and file name settings. + +run + Options controlling runtime behavior of Luaotfload. + +The list of valid variables, the sections they are part of and their +type is given below. Types represent Lua types that the values must be +convertible to; they are abbreviated as follows: ``s`` for the *string* +type, ``n`` for *number*, ``b`` for *boolean*. A value of ``nil`` means +the variable is unset. + + +Section ``db`` +----------------------------------------------------------------------- + ++---------------+--------+---------------------------+ +| variable | type | default | ++---------------+--------+---------------------------+ +| compress | b | ``true`` | ++---------------+--------+---------------------------+ +| formats | s | ``"otf,ttf,ttc,dfont"`` | ++---------------+--------+---------------------------+ +| max-fonts | n | ``2^51`` | ++---------------+--------+---------------------------+ +| scan-local | b | ``false`` | ++---------------+--------+---------------------------+ +| skip-read | b | ``false`` | ++---------------+--------+---------------------------+ +| strip | b | ``true`` | ++---------------+--------+---------------------------+ +| update-live | b | ``true`` | ++---------------+--------+---------------------------+ + +The flag ``compress`` determines whether the font index (usually +``luaotfload-names.lua[.gz]`` will be stored in compressed forms. +If unset it is equivalent of passing ``--no-compress`` to +**luaotfload-tool**. Since the file is only created for convenience +and has no effect on the runtime behavior of Luaotfload, the flag +should remain set. Most editors come with zlib support anyways. + +The list of ``formats`` must be a comma separated sequence of strings +containing one or more of these elements: + +* ``otf`` (OpenType format), +* ``ttf`` and ``ttc`` (TrueType format), +* ``dfont`` (Macintosh TrueType format), +* ``afm`` (Adobe Font Metrics), +* ``pfb`` and ``pfa`` (PostScript format). + +It corresponds loosely to the ``--formats`` option to +**luaotfload-tool**. Invalid or duplicate members are ignored; if the +list does not contain any useful identifiers, the default list +``"otf,ttf,ttc,dfont"`` will be used. + +The variable ``max-fonts`` determines after processing how many font +files the font scanner will terminate the search. This is useful for +debugging issues with the font index and has the same effect as the +option ``--max-fonts`` to **luaotfload-tools**. + +The ``scan-local`` flag, if set, will incorporate the current working +directory as a font search location. NB: This will potentially slow +down document processing because a font index with local fonts will not +be saved to disk, so these fonts will have to be re-indexed whenever +the document is built. + +The ``skip-read`` flag is only useful for debugging: It makes +Luaotfload skip reading fonts. The font information for rebuilding the +index is taken from the presently existing one. + +Unsetting the ``strip`` flag prevents Luaotfload from removing data +from the index that is only useful when processing font files. NB: this +can increase the size of the index files significantly and has no +effect on the runtime behavior. + +If ``update-live`` is set, Luaotfload will reload the database if it +cannot find a requested font. Those who prefer to update manually using +**luaotfload-tool** should unset this flag. + + +Section ``default-features`` +----------------------------------------------------------------------- + +By default Luaotfload enables ``node`` mode and picks the default font +features that are prescribed in the OpenType standard. This behavior +may be overridden in the ``default-features`` section. Global defaults +that will be applied for all scripts can be set via the ``global`` +option, others by the script they are to be applied to. For example, +a setting of :: + + [default-features] + global = mode=base,color=0000FF + dflt = smcp,onum + +would force *base* mode, tint all fonts blue and activate small +capitals and text figures globally. Features are specified as a comma +separated list of variables or variable-value pairs. Variables without +an explicit value are set to ``true``. + + +Section ``misc`` +----------------------------------------------------------------------- + ++---------------+--------+-------------------------+ +| variable | type | default | ++---------------+--------+-------------------------+ +| statistics | b | ``false`` | ++---------------+--------+-------------------------+ +| termwidth | n | ``nil`` | ++---------------+--------+-------------------------+ +| version | s | <Luaotfload version> | ++---------------+--------+-------------------------+ + +With ``statistics`` enabled, extra statistics will be collected during +index creation and appended to the index file. It may then be queried +at the Lua end or inspected by reading the file itself. + +The value of ``termwidth``, if set, overrides the value retrieved by +querying the properties of the terminal in which Luatex runs. This is +useful if the engine runs with ``shell_escape`` disabled and the actual +terminal dimensions cannot be retrieved. + +The value of ``version`` is derived from the version string hard-coded +in the Luaotfload source. Override at your own risk. + + +Section ``paths`` +----------------------------------------------------------------------- + ++------------------+--------+------------------------------------+ +| variable | type | default | ++------------------+--------+------------------------------------+ +| cache-dir | s | ``"fonts"`` | ++------------------+--------+------------------------------------+ +| names-dir | s | ``"names"`` | ++------------------+--------+------------------------------------+ +| index-file | s | ``"luaotfload-names.lua"`` | ++------------------+--------+------------------------------------+ +| lookups-file | s | ``"luaotfload-lookup-cache.lua"`` | ++------------------+--------+------------------------------------+ + +The paths ``cache-dir`` and ``names-dir`` determine the subdirectory +inside the Luaotfload subtree of the ``luatex-cache`` directory where +the font cache and the font index will be stored, respectively. + +Inside the index directory, the names of the index file and the font +lookup cache will be derived from the respective values of +``index-file`` and ``lookups-file``. This is the filename base for the +bytecode compiled version as well as -- for the index -- the gzipped +version. + + +Section ``run`` +----------------------------------------------------------------------- + ++------------------+--------+------------------------------+ +| variable | type | default | ++------------------+--------+------------------------------+ +| color-callback | s | ``"pre_linebreak_filter"`` | ++------------------+--------+------------------------------+ +| definer | s | ``"patch"`` | ++------------------+--------+------------------------------+ +| log-level | n | ``0`` | ++------------------+--------+------------------------------+ +| resolver | s | ``"cached"`` | ++------------------+--------+------------------------------+ + +The ``color-callback`` option determines the stage at which fonts that +defined with a ``color=xxyyzz`` feature will be colorized. By default +this happens in a ``pre_linebreak_filter`` but alternatively the +``pre_output_filter`` may be chosen, which is faster but might produce +inconsistent output. The latter also was the default in the 1.x series +of Luaotfload. + +The ``definer`` allows for switching the ``define_font`` callback. +Apart from the default ``patch`` one may also choose the ``generic`` +one that comes with the vanilla fontloader. Beware that this might +break tools like Fontspect that rely on the ``patch_font`` callback +provided by Luaotfload to perform important corrections on font data. + +The value of ``log-level`` sets the default verbosity of messages +printed by Luaotfload. Only messages defined with a verbosity of less +than or equal to the supplied value will be output on the terminal. +At a log level of five Luaotfload can be very noisy. Also, printing too +many messages will slow down the interpreter due to line buffering +being disabled (see **setbuf**\(3)). + +The ``resolver`` setting allows choosing the font name resolution +function: With the default value ``cached`` Luaotfload saves the result +of a successful font name request to a cache file to speed up +subsequent lookups. The alternative, ``normal`` circumvents the cache +and resolves every request individually. (Since to the restructuring of +the font name index in Luaotfload 2.4 the performance difference +between the cached and uncached lookups should be marginal.) + + +FILES +======================================================================= + +Luaotfload only processes the first configuration file it encounters at +one of the search locations. The file name may be either +``luaotfload.conf`` or ``luaotfloadrc``, except for the dotfile in the +user’s home directory which is expected at ``~/.luaotfloadrc``. + +Configuration files are located following a series of steps. The search +terminates as soon as a suitable file is encountered. The sequence of +locations that Luaotfload looks at is + +i. The current working directory of the LuaTeX process. +ii. The subdirectory ``luaotfload/`` inside the XDG configuration + tree, e. g. ``/home/oenothea/config/luaotfload/``. +iii. The dotfile. +iv.

A lot of -% files are needed for one font (\abbrev{tfm}, \abbrev{pfb}, \abbrev{map}, -% \abbrev{fd}, \abbrev{vf}), and due to the 8-Bit encoding each font is limited -% to 256 characters. -% But the font world has evolved since the original -% \TEX, and new typographic systems have appeared, most notably the so -% called \emphasis{smart font} technologies like \OpenType -% fonts (\abbrev{otf}). -% These fonts can contain many more characters than \TEX fonts, as well as additional -% functionality like ligatures, old-style numbers, small capitals, -% etc., and support more complex writing systems like Arabic and -% Indic\footnote{% -% Unfortunately, \identifier{luaotfload} doesn‘t support many Indic -% scripts right now. -% Assistance in implementing the prerequisites is greatly -% appreciated. -% } -% scripts. -% \OpenType fonts are widely deployed and available for all -% modern operating systems. -% As of 2013 they have become the de facto standard for advanced text -% layout. -% However, until recently the only way to use them directly in the \TEX -% world was with the \XETEX engine. -% -% Unlike \XETEX, \LUATEX has no built-in support for -% \OpenType or technologies other than the original \TEX fonts. -% Instead, it provides hooks for executing \LUA code during the \TEX run -% that allow implementing extensions for loading fonts and manipulating -% how input text is processed without modifying the underlying engine. -% This is where \identifier{luaotfload} comes into play: -% Based on code from \CONTEXT, it extends \LUATEX with functionality necessary -% for handling \OpenType fonts. -% Additionally, it provides means for accessing fonts known to the operating -% system conveniently by indexing the metadata. -% -% -% \section{Thanks} -% -% \identifier{Luaotfload} is part of \LUALATEX, the community-driven -% project to provide a foundation for using the \LATEX format with the -% full capabilites of the \LUATEX engine. -% As such, the distinction between end users, contributors, and project -% maintainers is intentionally kept less strict, lest we unduly -% personalize the common effort. -% -% Nevertheless, the current maintainers would like to express their -% gratitude to Khaled Hosny, Akira Kakuto, Hironori Kitagawa and Dohyun -% Kim. -% Their contributions -- be it patches, advice, or systematic -% testing -- made the switch from version 1.x to 2.2 possible. -% Also, Hans Hagen, the author of the font loader, made porting the -% code to \LATEX a breeze due to the extra effort he invested into -% isolating it from the rest of \CONTEXT, not to mention his assistance -% in the task and willingness to respond to our suggestions. -% -% -% \section{Loading Fonts} -% -% \identifier{luaotfload} supports an extended font request syntax: -% -% \begin{quote} -% |\font\foo={|% -% \meta{prefix}|:|% -% \meta{font name}|:|% -% \meta{font features}|}|% -% \meta{\TEX font features} -% \end{quote} -% -% \noindent -% The curly brackets are optional and escape the spaces in the enclosed -% font name. -% Alternatively, double quotes serve the same purpose. -% A selection of individual parts of the syntax are discussed

In \identifier{luaotfload}, the canonical syntax for font requests -% requires a \emphasis{prefix}: -% \begin{quote} -% |\font\fontname=|\meta{prefix}|:|\meta{fontname}\dots -% \end{quote} -% where \meta{prefix} is either \verb|file:| or \verb|name:|.\footnote{% -% The development version also knows two further prefixes, -% \verb|kpse:| and \verb|my:|. -% A \verb|kpse| lookup is restricted to files that can be found by -% \identifier{kpathsea} and -% will not attempt to locate system fonts. -% This behavior can be of value when an extra degree of encapsulation is -% needed, for instance when supplying a customized tex distribution. -% -% The \verb|my| lookup takes this a step further: it lets you define -% a custom resolver function and hook it into the \luafunction{resolve_font} -% callback. -% This ensures full control over how a file is located. -% For a working example see the -% \href{https://bitbucket.org/phg/lua-la-tex-tests/src/5f6a535d/pln-lookup-callback-1.tex} -% {test repo}. -% } -% It determines whether the font loader should interpret the request as -% a \emphasis{file name} or -% \emphasis{font name}, respectively, -% which again influences how it will attempt to locate the font. -% Examples for font names are -% “Latin Modern Italic”, -% “GFS Bodoni Rg”, and -% “PT Serif Caption” -% -- they are the human readable identifiers -% usually listed in drop-down menus and the like.\footnote{% -% Font names may appear like a great choice at first because they -% offer seemingly more intuitive identifiers in comparison to arguably -% cryptic file names: -% “PT Sans Bold” is a lot more descriptive than \fileent{PTS75F.ttf}. -% On the other hand, font names are quite arbitrary and there is no -% universal method to determine their meaning. -% While \identifier{luaotfload} provides fairly sophisticated heuristic -% to figure out a matching font style, weight, and optical size, it -% cannot be relied upon to work satisfactorily for all font files. -% For an in-depth analysis of the situation and how broken font names -% are, please refer to -% \href{http://www.ntg.nl/pipermail/ntg-context/2013/073889.html} -% {this post} -% by Hans Hagen, the author of the font loader. -% If in doubt, use filenames. -% \fileent{luaotfload-tool} can perform the matching for you with the -% option \verb|--find=<name>|, and you can use the file name it returns -% in your font definition. -% } -% In order for fonts installed both in system locations and in your -% \fileent{texmf} to be accessible by font name, \identifier{luaotfload} must -% first collect the metadata included in the files. -% Please refer to section~\ref{sec:fontdb} below for instructions on how to -% create the database. -% -% File names are whatever your file system allows them to be, except -% that that they may not contain the characters -% \verb|(|, -% \verb|:|, and -% \verb|/|. -% As is obvious from the last exception, the \verb|file:| lookup will -% not process paths to the font location -- only those -% files found when generating the database are addressable this way. -% Continue below in the \XETEX section if you need to load your fonts -% by path. -% The file names corresponding to the example font names above are -% \fileent{lmroman12-italic.otf}, -% \fileent{GFSBodoni.otf}, and -% \fileent{PTZ56F.ttf}. -% -% \subsection{Compatibility Layer} -% -% In addition to the regular prefixed requests, \identifier{luaotfload} -% accepts loading fonts the \XETEX way. -% There are again two modes: bracketed and unbracketed. -% A bracketed request looks as follows. -% -% \begin{quote} -% |\font\fontname=[|\meta{path to file}|]| -% \end{quote} -% -% \noindent -% Inside the square brackets, every character except for a closing -% bracket is permitted, allowing for specifying paths to a font file. -% Naturally, path-less file names are equally valid and processed the -% same way as an ordinary \verb|file:| lookup. -% -% \begin{quote} -% |\font\fontname=|\meta{font name} \dots -% \end{quote} -% -% Unbracketed (or, for lack of a better word: \emphasis{anonymous}) -% font requests resemble the conventional \TEX syntax. -% However, they have a broader spectrum of possible interpretations: -% before anything else, \identifier{luaotfload} attempts to load a -% traditional \TEX Font Metric (\abbrev{tfm} or \abbrev{ofm}). -% If this fails, it performs a \verb|name:| lookup, which itself will -% fall back to a \verb|file:| lookup if no database entry matches -% \meta{font name}. -% -% Furthermore, \identifier{luaotfload} supports the slashed (shorthand) -% font style notation from \XETEX. -% -% \begin{quote} -% |\font\fontname=|\meta{font name}|/|\meta{modifier}\dots -% \end{quote} -% -% \noindent -% Currently, four style modifiers are supported: -% \verb|I| for italic shape, -% \verb|B| for bold weight, -% \verb|BI| or \verb|IB| for the combination of both. -% Other “slashed” modifiers are too specific to the \XETEX engine and -% have no meaning in \LUATEX. -% -% \subsection{Examples} -% -% \subsubsection{Loading by File Name} -% -% For example, conventional \abbrev{type1} font can be loaded with a \verb|file:| -% request like so: -% -% \begin{quote} -% \begin{verbatim} -% \font\lmromanten={file:ec-lmr10} at 10pt -% \end{verbatim} -% \end{quote} -% -% The \OpenType version of Janusz Nowacki’s font \emphasis{Antykwa -% Półtawskiego}\footnote{% -% \url{http://jmn.pl/antykwa-poltawskiego/}, also available in -% in \TEX Live. -% } -% in its condensed variant can be loaded as follows: -% -% \begin{quote} -% \begin{verbatim} -% \font\apcregular=file:antpoltltcond-regular.otf at 42pt -% \end{verbatim} -% \end{quote} -% -% The next example shows how to load the \emphasis{Porson} font digitized by -% the Greek Font Society using \XETEX-style syntax and an absolute path from a -% non-standard directory: -% -% \begin{quote} -% \begin{verbatim} -% \font\gfsporson="[/tmp/GFSPorson.otf]" at 12pt -% \end{verbatim} -% \end{quote} -% -% \subsubsection{Loading by Font Name} -% -% The \verb|name:| lookup does not depend on cryptic filenames: -% -% \begin{quote} -% \begin{verbatim} -% \font\pagellaregular={name:TeX Gyre Pagella} at 9pt -% \end{verbatim} -% \end{quote} -% -% A bit more specific but essentially the same lookup would be: -% -% \begin{quote} -% \begin{verbatim} -% \font\pagellaregular={name:TeX Gyre Pagella Regular} at 9pt -% \end{verbatim} -% \end{quote} -% -% \noindent -% Which fits nicely with the whole set: -% -% \begin{quote} -% \begin{verbatim} -% \font\pagellaregular ={name:TeX Gyre Pagella Regular} at 9pt -% \font\pagellaitalic ={name:TeX Gyre Pagella Italic} at 9pt -% \font\pagellabold ={name:TeX Gyre Pagella Bold} at 9pt -% \font\pagellabolditalic={name:TeX Gyre Pagella Bolditalic} at 9pt -% -% {\pagellaregular foo bar baz\endgraf} -% {\pagellaitalic foo bar baz\endgraf} -% {\pagellabold foo bar baz\endgraf} -% {\pagellabolditalic foo bar baz\endgraf} -% -% ... -% \end{verbatim} -% \end{quote} -% -% \subsubsection{Modifiers} -% -% If the entire \emphasis{Iwona} family\footnote{% -% \url{http://jmn.pl/kurier-i-iwona/}, -% also in \TEX Live. -% } -% is installed in some location accessible by \identifier{luaotfload}, -% the regular shape can be loaded as follows: -% -% \begin{quote} -% \begin{verbatim} -% \font\iwona=Iwona at 20pt -% \end{verbatim} -% \end{quote} -% -% \noindent -% To load the most common of the other styles, the slash notation can -% be employed as shorthand: -% -% \begin{quote} -% \begin{verbatim} -% \font\iwonaitalic =Iwona/I at 20pt -% \font\iwonabold =Iwona/B at 20pt -% \font\iwonabolditalic=Iwona/BI at 20pt -% \end{verbatim} -% \end{quote} -% -% \noindent -% which is equivalent to these full names: -% -% \begin{quote} -% \begin{verbatim} -% \font\iwonaitalic ="Iwona Italic" at 20pt -% \font\iwonabold ="Iwona Bold" at 20pt -% \font\iwonabolditalic="Iwona BoldItalic" at 20pt -% \end{verbatim} -% \end{quote} -% -% \section{Font features} -% -% \emphasis{Font features} are the second to last component in the -% general scheme for font requests: -% -% \begin{quote} -% |\font\foo={|% -% \meta{prefix}|:|% -% \meta{font name}|:|% -% \meta{font features}|}|% -% \meta{\TEX font features} -% \end{quote} -% -% \noindent -% If style modifiers are present (\XETEX style), they must precede -% \meta{font features}. -% -% The element \meta{font features} is a semicolon-separated list of feature -% tags\footnote{% -% Cf. \url{http://www.microsoft.com/typography/otspec/featurelist.htm}. -% } -% and font options. -% Prepending a font feature with a |+| (plus sign) enables it, whereas -% a |-| (minus) disables it. For instance, the request -% -% \begin{quote} -% \begin{verbatim} -% \font\test=LatinModernRoman:+clig;-kern -% \end{verbatim} -% \end{quote} -% -% \noindent activates contextual ligatures (|clig|) and disables -% kerning (|kern|). -% Alternatively the options |true| or |false| can be passed to -% the feature in a key/value expression. -% The following request has the same meaning as the last one: -% -% \begin{quote} -% \begin{verbatim} -% \font\test=LatinModernRoman:clig=true;kern=false -% \end{verbatim} -% \end{quote} -% -% \noindent -% Furthermore, this second syntax is required should a font feature -% accept other options besides a true/false switch. -% For example, \emphasis{stylistic alternates} (|salt|) are variants of given -% glyphs. -% They can be selected either explicitly by supplying the variant -% index (starting from one), or randomly by setting the value to, -% obviously, |random|. -% -% \iffalse TODO verify that this actually works with a font that supports -% the salt/random feature!\fi -% \begin{quote} -% \begin{verbatim} -% \font\librmsaltfirst=LatinModernRoman:salt=1 -% \end{verbatim} -% \end{quote} -% -% \noindent Other font options include: -% -% \begin{description} -% -% \item [mode] \hfill \\ -% \identifier{luaotfload} has two \OpenType processing -% \emphasis{modes}: -% \identifier{base} and \identifier{node}. -% -% \identifier{base} mode works by mapping \OpenType -% features to traditional \TEX ligature and kerning mechanisms. -% Supporting only non-contextual substitutions and kerning -% pairs, it is the slightly faster, albeit somewhat limited, variant. -% \identifier{node} mode works by processing \TeX’s internal -% node list directly at the \LUA end and supports -% a wider range of \OpenType features. -% The downside is that the intricate operations required for -% \identifier{node} mode may slow down typesetting especially -% with complex fonts and it does not work in math mode. -% -% By default \identifier{luaotfload} is in \identifier{node} -% mode, and \identifier{base} mode has to be requested where needed, -% e.~g. for math fonts. -% -% \item [script] \label{script-tag} \hfill \\ -% An \OpenType script tag;\footnote{% -% See \url{http://www.microsoft.com/typography/otspec/scripttags.htm} -% for a list of valid values. -% For scripts derived from the Latin alphabet the value -% |latn| is good choice. -% } -% the default value is |dlft|. -% Some fonts, including very popular ones by foundries like Adobe, -% do not assign features to the |dflt| script, in -% which case the script needs to be set explicitly. -% -% \item [language] \hfill \\ -% An \OpenType language system identifier,\footnote{% -% Cf. \url{http://www.microsoft.com/typography/otspec/languagetags.htm}. -% } -% defaulting to |dflt|. -% -% \item [featurefile] \hfill \\ -% A comma-separated list of feature files to be applied to the -% font. -% Feature files contain a textual representation of -% \OpenType tables and extend the features of a font -% on fly. -% After they are applied to a font, features defined in a -% feature file can be enabled or disabled just like any -% other font feature. -% The syntax is documented in \identifier{Adobe}’s -% \OpenType Feature File Specification.\footnote{% -% Cf. \url{http://www.adobe.com/devnet/opentype/afdko/topic_feature_file_syntax.html}. -% } -% -% For a demonstration of how to set a |tkrn| feature consult -% the file |tkrn.fea| that is part of \identifier{luaotfload}. -% It can be read and applied as follows: -% -% |\font\test=Latin Modern Roman:featurefile=tkrn.fea;+tkrn| -% -% \item [color] \hfill \\ -% A font color, defined as a triplet of two-digit hexadecimal -% \abbrev{rgb} values, with an optional fourth value for -% transparency -% (where |00| is completely transparent and |FF| is opaque). -% -% For example, in order to set text in semitransparent red: -% -% \begin{quote} -% \begin{verbatim} -% \font\test={Latin Modern Roman}:color=FF0000BB -% \end{verbatim} -% \end{quote} -% -% \item [kernfactor \& letterspace] \hfill \\ -% Define a font with letterspacing (tracking) enabled. -% In \identifier{luaotfload}, letterspacing is implemented by -% inserting additional kerning between glyphs. -% -% This approach is derived from and still quite similar to the -% \emphasis{character kerning} (\texmacro{setcharacterkerning} / -% \texmacro{definecharacterkerning} \& al.) functionality of -% Context, see the file \fileent{typo-krn.lua} there. -% The main difference is that \identifier{luaotfload} does not -% use \LUATEX attributes to assign letterspacing to regions, -% but defines virtual letterspaced versions of a font. -% -% The option \identifier{kernfactor} accepts a numeric value that -% determines the letterspacing factor to be applied to the font -% size. -% E.~g. a kern factor of $0.42$ applied to a $10$ pt font -% results in $4.2$ pt of additional kerning applied to each -% pair of glyphs. -% Ligatures are split into their component glyphs unless -% explicitly ignored (see below). -% -% For compatibility with \XETEX an alternative -% \identifier{letterspace} option is supplied that interprets the -% supplied value as a \emphasis{percentage} of the font size but -% is otherwise identical to \identifier{kernfactor}. -% Consequently, both definitions in below snippet yield the same -% letterspacing width: -% -% \begin{quote} -% \begin{verbatim} -% \font\iwonakernedA="file:Iwona-Regular.otf:kernfactor=0.125" -% \font\iwonakernedB="file:Iwona-Regular.otf:letterspace=12.5" -% \end{verbatim} -% \end{quote} -% -% Specific pairs of letters and ligatures may be exempt from -% letterspacing by defining the \LUA functions -% \luafunction{keeptogether} and \luafunction{keepligature}, -% respectively, inside the namespace \verb|luaotfload.letterspace|. -% Both functions are called whenever the letterspacing callback -% encounters an appropriate node or set of nodes. -% If they return a true-ish value, no extra kern is inserted at -% the current position. -% \luafunction{keeptogether} receives a pair of consecutive -% glyph nodes in order of their appearance in the node list. -% \luafunction{keepligature} receives a single node which can be -% analyzed into components. -% (For details refer to the \emphasis{glyph nodes} section in the -% \LUATEX reference manual.) -% The implementation of both functions is left entirely to the -% user. -% -% -% \item [protrusion \& expansion] \hfill \\ -% These keys control microtypographic features of the font, -% namely \emphasis{character protrusion} and \emphasis{font -% expansion}. -% Their arguments are names of \LUA tables that contain -% values for the respective features.\footnote{% -% For examples of the table layout please refer to the -% section of the file \fileent{luaotfload-fonts-ext.lua} where the -% default values are defined. -% Alternatively and with loss of information, you can dump -% those tables into your terminal by issuing -% \begin{verbatim} -% \directlua{inspect(fonts.protrusions.setups.default) -% inspect(fonts.expansions.setups.default)} -% \end{verbatim} -% at some point after loading \fileent{luaotfload.sty}. -% } -% For both, only the set \identifier{default} is predefined. -% -% For example, to define a font with the default -% protrusion vector applied\footnote{% -% You also need to set -% \verb|pdfprotrudechars=2| and -% \verb|pdfadjustspacing=2| -% to activate protrusion and

\font\test=LatinModernRoman:protrusion=default -% \end{verbatim} -% \end{quote} -% \end{description} -% -% \paragraph{Non-standard font features} -% \identifier{luaotfload} adds a number of features that are not defined -% in the original \OpenType specification, most of them -% aiming at emulating the behavior familiar from other \TEX engines. -% Currently (2013) there are three of them: -% -% \begin{description} -% -% \item [anum] -% Substitutes the glyphs in the \abbrev{ascii} number range -% with their counterparts from eastern Arabic or Persian, -% depending on the value of \identifier{language}. -% -% \item [tlig] -% Applies legacy \TEX ligatures: -% -% \begin{tabular}{rlrl} -% `` & \verb|``| & '' & \verb|''| \\ -% ` & \verb|`| & ' & \verb|'| \\ -% " & \verb|"| & -- & \verb|--| \\ -% --- & \verb|---| & !` & \verb|!`| \\ -% ?` & \verb|?`| & & \\ -% \end{tabular} -% -% \footnote{% -% These contain the feature set \verb|trep| of earlier -% versions of \identifier{luaotfload}. -% -% Note to \XETEX users: this is the equivalent of the -% assignment \verb|mapping=text-tex| using \XETEX's input -% remapping feature. -% } -% -% \item [itlc] -% Computes italic correction values (active by default). -% -% \end{description} -% -% -% -% \section{Font names database} -% \label{sec:fontdb} -% -% As mentioned above, \identifier{luaotfload} keeps track of which -% fonts are available to \LUATEX by means of a \emphasis{database}. -% This allows referring to fonts not only by explicit filenames but -% also by the proper names contained in the metadata which is often -% more accessible to humans.\footnote{% -% The tool \href{http://www.lcdf.org/type/}{\fileent{otfinfo}} (comes -% with \TEX Live), when invoked on a font file with the \verb|-i| -% option, lists the variety of name fields defined for it. -% } -% -% When \identifier{luaotfload} is asked to load a font by a font name, -% it will check if the database exists and load it, or else generate a -% fresh one. -% Should it then fail to locate the font, an update to the database is -% performed in case the font has been added to the system only -% recently. As soon as the database is updated, the resolver will try -% and look up the font again, all without user intervention. -% The goal is for \identifier{luaotfload} to act in the background and -% behave as unobtrusively as possible, while providing a convenient -% interface to the fonts installed on the system. -% -% Generating the database for the first time may take a while since it -% inspects every font file on your computer. -% This is particularly noticeable if it occurs during a typesetting run. -% In any case, subsequent updates to the database will be quite fast. -% -% \subsection[luaotfload-tool / mkluatexfontdb.lua]% -% {\fileent{luaotfload-tool} / -% \fileent{mkluatexfontdb.lua}\footnote{% -% The script may be named just \fileent{mkluatexfontdb} in your -% distribution. -% }} -% -% It can still be desirable at times to do some of these steps -% manually, and without having to compile a document. -% To this end, \identifier{luaotfload} comes with the utility -% \fileent{luaotfload-tool} that offers an interface to the database -% functionality. -% Being a \LUA script, there are two ways to run it: -% either make it executable (\verb|chmod +x| on unixoid systems) or -% pass it as an argument to \fileent{texlua}.\footnote{% -% Tests by the maintainer show only marginal performance gain by -% running with Luigi Scarso’s -% \href{https://foundry.supelec.fr/projects/luajittex/}% -% {\identifier{Luajit\kern-.25ex\TEX}}, -% which is probably due to the fact that most of the time is spent -% on file system operations. -% -% \emphasis{Note}: -% On \abbrev{MS} \identifier{Windows} systems, the script can be run -% either by calling the wrapper application -% \fileent{luaotfload-tool.exe} or as -% \verb|texlua.exe

also provides rudimentary means of -% accessing the information collected in the font database. -% If the option \verb|--find=|\emphasis{name} is given, the script will -% try and search the fonts indexed by \identifier{luaotfload} for a -% matching name. -% For instance, the invocation -% -% \begin{quote} -% \begin{verbatim} -% luaotfload-tool --find="Iwona Regular" -% \end{verbatim} -% \end{quote} -% -% \noindent -% will verify if “Iwona Regular” is found in the database and can be -% readily requested in a document. -% -% If you are unsure about the actual font name, then add the -% \verb|-F| (or \verb|--fuzzy|) switch to the command line to enable -% approximate matching. -% Suppose you cannot precisely remember if the variant of -% \identifier{Iwona} you are looking for was “Bright” or “Light”. -% The query -% -% \begin{quote} -% \begin{verbatim} -% luaotfload-tool -F --find="Iwona Bright" -% \end{verbatim} -% \end{quote} -% -% \noindent -% will tell you that indeed the

\verb|luaotfload-tool.rst| in the source directory. -% } -% -% \subsection{Blacklisting Fonts} -% \label{font-blacklist} -% -% Some fonts are problematic in general, or just in \LUATEX. -% If you find that compiling your document takes far too long or eats -% away all your system’s memory, you can track down the culprit by -% running \verb|luaotfload-tool -v| to increase verbosity. -% Take a note of the \emphasis{filename} of the font that database -% creation fails with and append it to the file -% \fileent{luaotfload-blacklist.cnf}. -% -% A blacklist file is a list of font filenames, one per line. -% Specifying the full path to where the file is located is optional, the -% plain filename should suffice. -% File extensions (\fileent{.otf}, \fileent{.ttf}, etc.) may be omitted. -% Anything after a percent (|%|) character until the end of the line -% is ignored, so use this to add comments. -% Place this file to some location where the \identifier{kpse} -% library can find it, e.~g. -% \fileent{texmf-local/tex/luatex/luaotfload} if you are running -% \identifier{\TEX Live},\footnote{% -% You may have to run \verb|mktexlsr| if you created a new file in -% your \fileent{texmf} tree. -% } -% or just leave it in the working directory of your document. -% \identifier{luaotfload} reads all files named -% \fileent{luaotfload-blacklist.cnf} it finds, so the fonts in -% \fileent{./luaotfload-blacklist.cnf} extend the global blacklist. -% -% Furthermore, a filename prepended with a dash character (|-|) is -% removed from the blacklist, causing it to be temporarily whitelisted -% without modifying the global file. -% An example with explicit paths: -% -% \begin{verbatim} -% % example otf-blacklist.cnf -% /Library/Fonts/GillSans.ttc % Luaotfload ignores this font. -% -/Library/Fonts/Optima.ttc % This one is usable again, even if -% % blacklisted somewhere else. -% \end{verbatim} -% -% \section{Files from \CONTEXT and \LUATEX-Fonts} -% -% \identifier{luaotfload} relies on code originally written by Hans -% Hagen\footnote{% -% The creator of the \href{http://wiki.contextgarden.net}{\CONTEXT} -% format. -% } -% for and tested with \CONTEXT. -% It integrates the font loader as distributed in -% the \identifier{\LUATEX-Fonts} package. -% The original \LUA source files have been combined using the -% \fileent{mtx-package} script into a single, self-contained blob. -% In this form the font loader has no further dependencies\footnote{% -% It covers, however, to some extent the functionality of the -% \identifier{lualibs} package. -% } -% and requires only minor adaptions to integrate into -% \identifier{luaotfload}. -% The guiding principle is to let \CONTEXT/\LUATEX-Fonts take care of -% the implementation, and update the imported code from time to time. -% As maintainers, we aim at importing files from upstream essentially -% \emphasis{unmodified}, except for renaming them to prevent name -% clashes. -% This job has been greatly alleviated since the advent of -% \LUATEX-Fonts, prior to which the individual dependencies had to be -% manually spotted and extracted from the \CONTEXT source code in a -%

release version 2.2, \identifier{luaotfload} received -% additional functions for package authors to call from outside -% (see the file \fileent{luaotfload-auxiliary.lua} for details). -% The purpose of this addition twofold. -% Firstly, \identifier{luaotfload} failed to provide a stable interface -% to internals in the past which resulted in an unmanageable situation -% of different packages abusing the raw access to font objects by means -% of the \luafunction{patch_font} callback. -% When the structure of the font object changed due to an update, all -% of these imploded and several packages had to be fixed while -% simultaneously providing fallbacks for earlier versions. -% Now the patching is done on the \identifier{luaotfload} side and can -% be adapted with future modifications to font objects without touching -% the packages that depend on it. -% Second, some the capabilities of the font loader and the names -% database are not immediately relevant in \identifier{luaotfload} -% itself but might nevertheless be of great value to package authors or -% end users. -% -% Note that the current interface is not yet set in stone and the -% development team is open to suggestions for improvements or -% additions. -% -% \subsection{Callback Functions} -% -% The \luafunction{patch_font} callback is inserted in the wrapper -% \identifier{luaotfload} provides for the font definition callback -% (see below, page \pageref{define-font}). -% At this place it allows manipulating the font object immediately after -% the font loader is done creating it. -% For a short demonstration of its usefulness, here is a snippet that -% writes an entire font object to the file \fileent{fontdump.lua}: -% -% \begin{quote} -% \begin{verbatim} -% \input luaotfload.sty -% \directlua{ -% local dumpfile = "fontdump.lua" -% local dump_font = function (tfmdata) -% local data = table.serialize(tfmdata) -% io.savedata(dumpfile, data) -% end -% -% luatexbase.add_to_callback( -% "luaotfload.patch_font", -% dump_font, -% "my_private_callbacks.dump_font" -% ) -% } -% \font\dumpme=name:Iwona -% \bye -% \end{verbatim} -% \end{quote} -% -% \emphasis{Beware}: this creates a Lua file of around 150,000 lines of -% code, taking up 3~\abbrev{mb} of disk space. -% By inspecting the output you can get a first impression of how a font -% is structured in \LUATEX’s memory, what elements it is composed of, -% and in what ways it can be rearranged. -% -% \subsubsection{Compatibility with Earlier Versions} -% -% As has been touched on in the preface to this section, the structure -% of the object as returned by the fontloader underwent rather drastic -% changes during different stages of its development, and not all -% packages that made use of font patching have kept up with every one -% of it. -% To ensure compatibility with these as well as older versions of -% some packages, \identifier{luaotfload} sets up copies of or references -% to data in the font table where it used to be located. -% For instance, important parameters like the requested point size, the -% units factor, and the font name have again been made accessible from -% the toplevel of the table even though they were migrated to different -% subtables in the meantime. -% -% \subsubsection{Patches} -% -% These are mostly concerned with establishing compatibility with -% \XETEX. -% -% \begin{itemize} -% \let\normalitem=\item -% \def\ouritem#1{% -% \normalitem{\luafunction{#1}}% -% \hfill\break -% } -% -% \ouritem {set_sscale_dimens} -% Calculate \texmacro{fontdimen}s 10 and 11 to emulate \XETEX. -% -% \ouritem {set_capheight} -% Calculates \texmacro{fontdimen} 8 like \XETEX. -% -% \ouritem {patch_cambria_domh} -% Correct some values of the font \emphasis{Cambria Math}. -% -% \end{itemize} -% -% \subsection{Package Author’s Interface} -% -% As \LUATEX release 1.0 is nearing, the demand for a reliable interface -% for package authors increases. -% -% \subsubsection{Font Properties} -% -% Below functions mostly concern querying the different components of a -% font like for instance the glyphs it contains, or what font features -% are defined for which scripts. -% -% \begin{itemize} -% \let\normalitem=\item -% \def\ouritem#1{% -% \normalitem{\luafunction{#1}}% -% \hfill\break -% } -% -% \ouritem {aux.font_has_glyph (id : int, index : int)} -% Predicate that returns true if the font \luafunction{id} -% has glyph \luafunction{index}. -% -% \ouritem {aux.slot_of_name(name : string)} -% Translates an Adobe Glyph name to the corresponding glyph -% slot. -% -% \ouritem {aux.name_of_slot(slot : int)} -% The inverse of \luafunction{slot_of_name}; note that this -% might be incomplete as multiple glyph names may map to the -% same codepoint, only one of which is returned by -% \luafunction{name_of_slot}. -% -% \ouritem {aux.provides_script(id : int, script : string)} -% Test if a font supports \luafunction{script}. -% -% \ouritem {aux.provides_language(id : int, script : string, language : string)} -% Test if a font defines \luafunction{language} for a given -% \luafunction{script}. -% -% \ouritem {aux.provides_feature(id : int, script : string, -% language : string, feature : string)} -% Test if a font defines \luafunction{feature} for -% \luafunction{language} for a given \luafunction{script}. -% -% \ouritem {aux.get_math_dimension(id : int, dimension : string)} -% Get the dimension \luafunction{dimension} of font \luafunction{id}. -% -% \ouritem {aux.sprint_math_dimension(id : int, dimension : string)} -% Same as \luafunction{get_math_dimension()}, but output the value -% in scaled points at the \TEX end. -% -% \end{itemize} -% -% \subsubsection{Database} -% -% \begin{itemize} -% \let\normalitem=\item -% \def\ouritem#1{% -% \normalitem{\luafunction{#1}}% -% \hfill\break -% } -% -% \ouritem {aux.scan_external_dir(dir : string)} -% Include fonts in directory \luafunction{dir} in font lookups without -% adding them to the database. -% -% \end{itemize} -% -% \section{Troubleshooting} -% -% \subsection {Database Generation} -% If you encounter problems with some fonts, please first update to the latest -% version of this package before reporting a bug, as -% \identifier{luaotfload} is under active development and still a -% moving target. -% The development takes place on \identifier{github} at -% \url{https://github.com/lualatex/luaotfload} where there is an issue -% tracker for submitting bug reports, feature requests and the likes -% requests and the likes. -% -% Bug reports are more likely to be addressed if they contain the output of -% -% \begin{quote} -% \begin{verbatim} -% luaotfload-tool --diagnose=environment,files,permissions -% \end{verbatim} -% \end{quote} -% -% \noindent Consult the man page for a description of these options. -% -% Errors during database generation can be traced by increasing the -% verbosity level and redirecting log output to \fileent{stdout}: -% -% \begin{quote} -% \begin{verbatim} -% luaotfload-tool -fuvvv --log=stdout -% \end{verbatim} -% \end{quote} -% -% \noindent or to a file in \fileent{/tmp}: -% -% \begin{quote} -% \begin{verbatim} -% luaotfload-tool -fuvvv --log=file -% \end{verbatim} -% \end{quote} -% -% \noindent In the latter case, invoke the \verb|tail(1)| utility on the file -% for live monitoring of the progress. -% -% If database generation fails, the font last printed to the terminal or log -% file is likely to be the culprit. -% Please specify it when reporting a bug, and blacklist it for the time -% being (see above, page \pageref{font-blacklist}). -% -% \subsection {Font Features} -% A common problem is the lack of features for some -% \OpenType fonts even when specified. -% This can be related to the fact that some fonts do not provide -% features for the \verb|dflt| script (see above on page -% \pageref{script-tag}), -% which is the default one in this package. -% If this happens, assigning a noth script when the font is defined should -% fix it. -% For example with \verb|latn|: -% -% \begin{quote} -% \begin{verbatim} -% \font\test=file:MyFont.otf:script=latn;+liga; -% \end{verbatim} -% \end{quote} -% -% You can get a list of features that a font defines for scripts and languages -% by querying it in \fileent{luaotfload-tool}: -% -% \begin{quote} -% \begin{verbatim} -% luaotfload-tool --find="Iwona" --inspect -% \end{verbatim} -% \end{quote} -% -% \subsection {\LUATEX Programming} -% Another strategy that helps avoiding problems is to not access raw \LUATEX -% internals directly. -% Some of them, even though they are dangerous to access, have not been -% overridden or disabled. -% Thus, whenever possible prefer the functions in the -% \luafunction{aux} namespace over direct manipulation of font objects. -% For example, raw access to the \luafunction{font.fonts} table like: -% -% \begin{quote} -% \begin{verbatim} -% local somefont = font.fonts[2] -% \end{verbatim} -% \end{quote} -% -% \noindent can render already defined fonts unusable. -% Instead, the function \luafunction{font.getfont()} should be used because -% it has been replaced by a safe variant. -% -% However, \luafunction{font.getfont()} only covers fonts handled by the font -% loader, e.~g. \identifier{OpenType} and \identifier{TrueType} fonts, but -% not \abbrev{tfm} or \abbrev{ofm}. -% Should you absolutely require access to all fonts known to \LUATEX, including -% the virtual and autogenerated ones, then you need to query both -% \luafunction{font.getfont()} and \luafunction{font.fonts}. -% In this case, best define you own accessor: -% -% \begin{quote} -% \begin{verbatim} -% local unsafe_getfont = function (id) -% local tfmdata = font.getfont (id) -% if not tfmdata then -% tfmdata = font.fonts[id] -% end -% return tfmdata -% end -% -% --- use like getfont() -% local somefont = unsafe_getfont (2) -% \end{verbatim} -% \end{quote} -% -% \part{Implementation} -% -% \section{\fileent{luaotfload.lua}} -% -% This file initializes the system and loads the font loader. -% To minimize potential conflicts between other packages and the -% code imported from \CONTEXT, several precautions are in order. -% Some of the functionality that the font loader expects to be present, -% like raw access to callbacks, are assumed to have been disabled by -% \identifier{luatexbase} when this file is processed. -% In some cases it is possible to trick it by putting dummies into -% place and restoring the behavior from \identifier{luatexbase} after -% initilization. -% Other cases such as attribute allocation require that we hook the -% functionality from \identifier{luatexbase} into locations where they -% normally wouldn’t be. -% -% Anyways we can import the code base without modifications, which is -% due mostly to the extra effort by -% Hans Hagen to make \LUATEX-Fonts self-contained and encapsulate it, -% and especially due to his willingness to incorporate our suggestions. -% -% \iffalse -%<*lua> -% \fi -% \begin{macrocode} -luaotfload =

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