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 `[', `]', [ [`:'], ] ;

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. -%

\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

\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

\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 -%

\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)}

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

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.
