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 below; +% for a more formal description see figure \ref{font-syntax}. +% +% \begin{figure}[b] +% \setlength\grammarparsep{12pt plus 2pt minus 2pt} +% \setlength\grammarindent{5cm} +% \begingroup +% \small +% \begin{grammar} +% ::= `\\font', {\sc csname}, `=', , [ ] ; +% +% ::= `at', {\sc dimension} ; +% +% ::= `"', `"' +% \alt `{', `}' +% \alt ; +% +% ::= , [`:', ] +% \alt `[', `]', [ [`:'], ] ; +% +% ::= , [ ], \{ \} +% \alt , \{ \} ; +% +% ::= `file:', +% \alt `name:', ; +% +% ::= \{ \} ; +% +% ::= \{ \} ; +% +% ::= {\sc tfmname} | ; +% +% ::= \{ {\sc all_characters} - `]' \} ; +% +% ::= `/', (`I' | `B' | `BI' | `IB' | `S=', \{ {\sc digit} \} ) ; +% +% ::= `(', \{ {\sc digit} \}, `)' ; +% +% ::= , \{ `;', \} ; +% +% ::= {\sc feature_id}, `=', {\sc feature_value} +% \alt , {\sc feature_id} ; +% +% ::= `+' | `-' ; +% +% ::= {\sc all_characters} - ( `(' | `/' | `:' ) ; +% \end{grammar} +% \endgroup +% \caption{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: {\ttfamily aat}, +% {\ttfamily icu}, and +% {\ttfamily gr}. +% The special terminals are: +% {\sc feature\textunderscore id} for a valid font +% feature name and +% {\sc feature\textunderscore value} for the corresponding +% value. +% {\sc tfmname} is the name of a \abbrev{tfm} file. +% {\sc digit} again refers to bytes 48--57, and +% {\sc all\textunderscore characters} to all byte values. +% {\sc csname} and {\sc dimension} are the \TEX concepts.} +% \label{font-syntax} +% \end{figure} +% +% \subsection{Prefix -- the \identifier{luaotfload}{ }Way} +% +% 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=|, 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 expansion, respectively. +% See the +% \href{http://mirrors.ctan.org/systems/pdftex/manual/pdftex-a.pdf}% +% {\PDFTEX manual} +% for details. +% }: +% +% \begin{quote} +% \begin{verbatim} +% \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 (2014) 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 luaotfload-tool.lua|. +% } +% Invoked with the argument \verb|--update| it will perform a database +% update, scanning for fonts not indexed. +% +% \begin{quote} +% \begin{verbatim} +% luaotfload-tool --update +% \end{verbatim} +% \end{quote} +% +% Adding the \verb|--force| switch will initiate a complete +% rebuild of the database. +% +% \begin{quote} +% \begin{verbatim} +% luaotfload-tool --update --force +% \end{verbatim} +% \end{quote} +% +% For sake of backwards compatibility, \fileent{luaotfload-tool} may be +% renamed or symlinked to \fileent{mkluatexfontdb}. +% Whenever it is run under this name, it will update the database +% first, mimicking the behavior of earlier versions of +% \identifier{luaotfload}. +% +% \subsection{Search Paths} +% +% \identifier{luaotfload} scans those directories where fonts are +% expected to be located on a given system. +% On a Linux machine it follows the paths listed in the +% \identifier{Fontconfig} configuration files; +% consult \verb|man 5 fonts.conf| for further information. +% On \identifier{Windows} systems, the standard location is +% \verb|Windows\Fonts|, +% while \identifier{Mac OS~X} requires a multitude of paths to +% be examined. +% The complete list is is given in table \ref{table-searchpaths}. +% Other paths can be specified by setting the environment variable +% \verb+OSFONTDIR+. +% If it is non-empty, then search will be extended to the included +% directories. +% +% \begin{table}[t] +% \hrule +% \caption{List of paths searched for each supported operating +% system.} +% \renewcommand{\arraystretch}{1.2} +% \begin{center} +% \begin{tabular}{lp{.5\textwidth}} +% Windows & \verb|%WINDIR%\Fonts| +% \\ +% Linux & \fileent{/usr/local/etc/fonts/fonts.conf} and\hfill\break +% \fileent{/etc/fonts/fonts.conf} +% \\ +% Mac & \fileent{\textasciitilde/Library/Fonts},\break +% \fileent{/Library/Fonts},\break +% \fileent{/System/Library/Fonts}, and\hfill\break +% \fileent{/Network/Library/Fonts} +% \\ +% \end{tabular} +% \end{center} +% \label{table-searchpaths} +% \hrule +% \end{table} +% +% \subsection{Querying from Outside} +% +% \fileent{luaotfload-tool} 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 latter name is correct. +% +% Basic information about fonts in the database can be displayed +% using the \verb|-i| option (\verb|--info|). +% \begin{quote} +% \begin{verbatim} +% luaotfload-tool -i --find="Iwona Light Italic" +% \end{verbatim} +% \end{quote} +% \noindent +% The meaning of the printed values is described in section 4.4 of the +% \LUATEX reference manual.\footnote{% +% In \TEX Live: \fileent{texmf-dist/doc/luatex/base/luatexref-t.pdf}. +% } +% +% For a much more detailed report about a given font try the \verb|-I| option +% instead (\verb|--inspect|). +% \begin{quote} +% \begin{verbatim} +% luaotfload-tool -I --find="Iwona Light Italic" +% \end{verbatim} +% \end{quote} +% +% \verb|luaotfload-tool --help| will list the available command line +% switches, including some not discussed in detail here. +% For a full documentation of \identifier{luaotfload-tool} and its +% capabilities refer to the manpage +% (\verb|man 1 luaotfload-tool|).\footnote{% +% Or see \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 +% complicated and error-prone fashion. +% +% Below is a commented list of the files distributed with +% \identifier{luaotfload} in one way or the other. +% See figure \ref{file-graph} on page \pageref{file-graph} for a +% graphical representation of the dependencies. +% From \LUATEX-Fonts, only the file \fileent{luatex-fonts-merged.lua} +% has been imported as \fileent{luaotfload-fontloader.lua}. +% It is generated by \fileent{mtx-package}, a \LUA source code merging +% too developed by Hans Hagen.\footnote{% +% \fileent{mtx-package} is +% \href +% {http://repo.or.cz/w/context.git/blob_plain/refs/heads/origin:/scripts/context/lua/mtx-package.lua} +% {part of \CONTEXT} +% and requires \fileent{mtxrun}. +% Run +% \verb|mtxrun --script package --help| +% to display further information. +% For the actual merging code see the file +% \fileent{util-mrg.lua} that is part of \CONTEXT. +% } +% It houses several \LUA files that can be classed in three +% categories. +% +% \begin{itemize} +% \let\normalitem=\item +% \def\incitem#1{% +% \normalitem{\fileent{#1}} +% } +% \normalitem \emphasis{\LUA utility libraries}, a subset +% of what is

\identifier{luaotfload} cannot locate the +% merged file, it will load the individual \LUA libraries +% instead. +% Their names remain the same as in \CONTEXT (without the +% \verb|otfl|-prefix) since we imported the relevant section of +% \fileent{luatex-fonts.lua} unmodified into \fileent{luaotfload-main.lua}. +% Thus if you prefer running bleeding edge code from the +% \CONTEXT beta, all you have to do is remove +% \fileent{luaotfload-merged.lua} from the search path. +% +% Also, the merged file at some point +% loads the Adobe Glyph List from a \LUA table that is contained in +% \fileent{luaotfload-glyphlist.lua}, which is automatically generated by the +% script \fileent{mkglyphlist}.\footnote{% +% See \fileent{luaotfload-font-enc.lua}. +% The hard-coded file name is why we have to replace the procedure +% that loads the file in \fileent{luaotfload-override.lua}. +% } +% There is a make target \identifier{glyphs} that will create a fresh +% glyph list so we don’t need to import it from \CONTEXT +% any longer. +% +% In addition to these, \identifier{luaotfload} requires a number of +% files not contained in the merge. Some of these have no equivalent in +% \LUATEX-Fonts or \CONTEXT, some were taken unmodified from the +% latter. +% +% \begin{itemize} +% \let\normalitem=\item +% \def\ouritem#1{% +%

letterspacing. +% \end{itemize} +% +% \begin{figure}[b] +% \caption{Schematic of the files in \identifier{Luaotfload}} +% \includegraphics[width=\textwidth]{filegraph.pdf} +% \label{file-graph} +% \end{figure} +% +% \section{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. +% +% \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

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

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. 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.} +% +% \item +% {\sc 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{enumerate} +% +% +% \begin{center} +% {\Large\sc End of Terms and Conditions} +% \end{center} +% +% +% \pagebreak[2] +% +% \section*{Appendix: 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. +% +% \begin{quote} +% one line to give the program's name and a brief idea of what it does. \\ +% Copyright (C) yyyy 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. +% \end{quote} +% +% 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: +% +% \begin{quote} +% Gnomovision version 69, Copyright (C) yyyy 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. +% \end{quote} +% +% +% The hypothetical commands {\tt show w} and {\tt show c} should show the +% appropriate parts of the General Public License. Of course, the commands +% you use may be called something other than {\tt show w} and {\tt show c}; +% they could even be mouse-clicks or menu items---whatever suits your +% program. +% +% You should also get your employer (if you work as a programmer) or your +% school, if any, to sign a ``copyright disclaimer'' for the program, if +% necessary. Here is a sample; alter the names: +% +% \begin{quote} +% Yoyodyne, Inc., hereby disclaims all copyright interest in the program \\ +% `Gnomovision' (which makes passes at compilers) written by James Hacker. \\ +% +% signature of Ty Coon, 1 April 1989 \\ +% Ty Coon, President of Vice +% \end{quote} +% +% +% This General Public License does not permit incorporating your program +% into proprietary programs.

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 below; -% for a more formal description see figure \ref{font-syntax}. -% -% \begin{figure}[b] -% \setlength\grammarparsep{12pt plus 2pt minus 2pt} -% \setlength\grammarindent{5cm} -% \begingroup -% \small -% \begin{grammar} -% ::= `\\font', {\sc csname}, `=', , [ ] ; -% -% ::= `at', {\sc dimension} ; -% -% ::= `"', `"' -% \alt `{', `}' -% \alt ; -% -% ::= , [`:', ] -% \alt `[', `]', [ [`:'], ] ;

{\sc feature\textunderscore value} for the corresponding -% value. -% {\sc tfmname} is the name of a \abbrev{tfm} file. -% {\sc digit} again refers to bytes 48--57, and -% {\sc all\textunderscore characters} to all byte values. -% {\sc csname} and {\sc dimension} are the \TEX concepts.} -% \label{font-syntax} -% \end{figure} -% -% \subsection{Prefix -- the \identifier{luaotfload}{ }Way} -% -% 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=|, 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: -% -%

\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. -%

that are not defined -% in the original \OpenType specification, most of them -% aiming at emulating the behavior familiar from other \TEX engines. -% Currently (2014) 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

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

under this name, it will update the database -% first, mimicking the behavior of earlier versions of -% \identifier{luaotfload}. -% -% \subsection{Search Paths} -% -% \identifier{luaotfload} scans those directories where fonts are -% expected to be located on a given system. -% On a Linux machine it follows the paths listed in the -% \identifier{Fontconfig} configuration files; -% consult \verb|man 5 fonts.conf| for further information. -% On \identifier{Windows} systems, the standard location is -% \verb|Windows\Fonts|, -% while \identifier{Mac OS~X} requires a multitude of paths to

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 latter name is correct. -% -% Basic information about fonts in the database can be displayed -% using the \verb|-i| option (\verb|--info|). -% \begin{quote} -% \begin{verbatim} -% luaotfload-tool -i

\begin{verbatim} -% luaotfload-tool -I --find="Iwona Light Italic" -% \end{verbatim} -% \end{quote} -% -% \verb|luaotfload-tool --help| will list the available command line -% switches, including some

\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 -%

\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}} -% -% As of version 2.5, the file \fileent{luaotfload.lua} is no

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.
