Over time, \XeTeX\ was extended to support OpenType % fonts and then was ported into a cross-platform program to run also on Windows % and Linux. % % More recently, \LuaTeX\ is fast becoming the \TeX\ engine of the day; it % supports Unicode encodings and OpenType fonts and opens up the internals of % \TeX\ via the Lua programming language. Hans Hagen's Con\TeX t Mk.\,IV is a % re-write of his powerful typesetting system, taking full advantage of % \LuaTeX's features including font support; a kernel of his work in this area % has been extracted to be useful for other \TeX\ macro systems as well, and % this has enabled \pkg{fontspec} to be adapted for \LaTeX\ when run with the % \LuaTeX\ engine. Elie Roux and Khaled Hosny have been instrumental and % invaluable with this development work. % % \section{Introduction} % % The \pkg{fontspec} package allows users of either \XeTeX\ or \LuaTeX\ to % load OpenType fonts in a \LaTeX\ document. No font installation is necessary, % and font features can be selected and used as desired throughout the document. % % Without \pkg{fontspec}, it is necessary to write cumbersome font definition % files for \LaTeX, since \LaTeX's font selection scheme (known as the % `\textsc{nfss}') has a lot going on behind the scenes to allow easy % commands like \cmd\emph\ or \cmd\bfseries. With an uncountable number of % fonts now available for use, however, it becomes less desirable to have to % write these font definition (|.fd|) files for every font one wishes to use. % % Because \pkg{fontspec} is designed to work in a variety of modes, this % user documentation is split into separate sections that are designed to be % relatively independent. Nonetheless, the basic functionality all behaves in % the same way, so previous users of \pkg{fontspec} under \XeTeX\ should have % little or no difficulty switching over to \LuaTeX. % % This manual can get rather in-depth, as there are a lot of details % to cover. See the example documents \path{fontspec-xetex.tex} and % \path{fontspec-luatex.tex} for a complete minimal example with each engine. % % \subsection{About this manual} % % This document is typeset with pdf\LaTeX\ using pre-compiled examples % that have been generated by either \XeTeX\ or \LuaTeX. You may regenerate % the examples by removing the \verb|doc-files/| subdirectory and typesetting the % manual with the following invocation: % \begin{Verbatim} % pdflatex -shell-escape fontspec.dtx % \end{Verbatim} % Note that many of the examples use fonts that are not included in \TeX~Live % or MiKTeX, and some of them are non-free fonts that must be purchased. % % I'd like to reduce the number of non-free fonts used in this % manual. If you know any freely available fonts that could be used % as alternative to any of the fonts in this document, please suggest them % to me. % Finally, if any aspect of the documentation is unclear or you would % like to suggest more examples that could be made, get in touch. % (Contributions especially welcome.) % % \subsection{Acknowledgements} % % This package couldn't be possible without the early and continued support % the author of \XeTeX, Jonathan Kew. When I started this package, he steered % me many times in the right direction. % % I've had great % feedback over the years on feature requests, documentation queries, bug reports, font suggestions, and so on from lots of people all around the world. % Many thanks to you all. % % Thanks to David Perry and Markus B\"ohning for numerous documentation % improvements and David Perry again for contributing the text for one of the % sections of this manual. % % Special thanks to Khaled Hosny, who had been the driving force behind the support for \LuaLaTeX, ultimately leading to version 2.0 of the package. % % \section{Package loading and options} % % For basic use, no package options are required: % \begin{Verbatim} % \usepackage{fontspec} % \end{Verbatim} % % \paragraph{\pkg{xunicode}} % Ross Moore's \pkg{xunicode} package is now automatically loaded for % users of both \XeLaTeX\ and \LuaLaTeX. % This package provides backwards compatibility with \LaTeX's methods for accessing extra % characters and accents (for example, |\%|, |\$|, |\textbullet|, |\"u|, and % so on), plus many more Unicode characters. % \textbf{Warning}: introduced in v2.1, this is a backwards incompatible change to previous % versions of \pkg{fontspec}. This change was necessary in order to provide consistent % support for users of \XeTeX\ and \LuaTeX. I'm not aware of any issues this % may cause but please let me know if you run into problems. % % \paragraph{\XeTeX\ users only} % The \pkg{xltxtra} package adds some minor extra features to \XeLaTeX, including, via the \pkg{metalogo} package, the % \cmd\XeTeX\ macro to typeset the \XeTeX\ logo. While this package was % previously recommended, it serves a much smaller r\^ole nowadays and generally % will not be required. % % \paragraph{\LuaTeX\ users only} % In order to load fonts by their name rather than by their filename (\eg, % `Latin Modern Roman' instead of `ec-lmr10'), you may need to run the script % \texttt{mkluatexfontdb}, which is distributed with the \pkg{luaotfload} % package. Note that if you do not execute this script beforehand, the first % time you attempt to typeset the process will pause for (up to) several % minutes. (But only the first time.) % Please see the \pkg{luaotfload} documentation for more information. % % \paragraph{\pkg{babel}} % \emph{The \pkg{babel} package is not really supported!} Especially Vietnamese, % Greek, and Hebrew at least might not work correctly, as far as I can tell. % There's a better chance with Cyrillic and Latin-based languages, % however---\pkg{fontspec} ensures at least that fonts should load correctly, % but hyphenation and other matters aren't guaranteed. Under \XeTeX, the % \pkg{polyglossia} package is recommended instead as a modern replacement for % \pkg{babel}. % % % % \subsection{Maths fonts adjustments} % By default, \pkg{fontspec} adjusts \LaTeX's % default maths setup in order to maintain the correct Computer Modern symbols % when the roman font changes. However, it will attempt to avoid doing this if % another maths font package is loaded (such as \pkg{mathpazo} or the % \pkg{unicode-math} package). % % If you find that \pkg{fontspec} is incorrectly changing the maths font when it should be % leaving well enough alone, apply the |[no-math]| package option to manually % suppress its maths font. % % \subsection{Configuration} If you wish to customise any part of the % \pkg{fontspec} interface (see later in this manual, \vref{sec:newfeatures} % and~\ref{sec:aliasfontfeature}), this should be done by creating your own % \texttt{fontspec.cfg} file, % which will be automatically loaded if it is found by \XeTeX\ or \LuaTeX. Either place it % in the same folder as the main document for isolated cases, or in a location % that \XeTeX\ or \LuaTeX\ searches by default; \eg\ in Mac\TeX: \path{~/Library/texmf/tex/latex/}. % The package option |[no-config]| will suppress this behaviour under all circumstances. % % \subsection{Warnings} % \label{sec:quiet-warnings} % % This package can give many warnings that can be harmless if you know what % you're doing. Use the |[quiet]| package option to write these warnings to the % transcript (\texttt{.log}) file instead. % % Use the |[silent]| package option to completely suppress these warnings if you % don't even want the |.log| file cluttered up. % % % % % % \part{General font selection} % % This section concerns the variety of commands that can be used to select % fonts. % % \cmdbox{% % \CMD{\string\fontspec} \oarg{font features} \marg{font name}\\ % \CMD{\string\setmainfont} \oarg{font features} \marg{font name}\\ % \CMD{\string\setsansfont} \oarg{font features} \marg{font name}\\ % \CMD{\string\setmonofont} \oarg{font features} \marg{font name}\\ % \CMD{\string\newfontfamily} \meta{cmd} \oarg{font features} \marg{font name} % } % % These are the main font-selecting commands of this package. % The \cs{fontspec} command selects a font for one-time use; all % others should be used to define the standard fonts used in a document. % They will be described later in this section. % % The font features argument accepts comma separated % \meta{font feature}=\meta{option} lists; these are described in later: % \begin{itemize} % \item For general font features, see \vref{sec:font-ind-features} % \item For OpenType fonts, see Part~\vref{sec:opentype-features} % \item For \XeTeX-only general font features, see Part~\vref{sec:xetex-features} % \item For \LuaTeX-only general font features, see Part~\vref{sec:luatex-features} % \item For features for \AAT\ fonts in \XeTeX, see \vref{sec:aat-features} % \end{itemize} % % \section{Font selection} % % In both \LuaTeX\ and \XeTeX, fonts can be selected either by `font name' or % by `file name'. % % \subsection{By font name} % % Fonts known to \LuaTeX\ or \XeTeX\ may be loaded by their names. % `Known to' in this case generally means `exists in a standard fonts location' % such as |~/Library/Fonts| on \MacOSX, or |C:\Windows\Fonts| on Windows. % % The simplest example might be something like % \begin{Verbatim} % \fontspec[ ... ]{Cambria} % \end{Verbatim} % in which the bold and italic fonts will be found automatically % (if they exist) and are immediately accessible with the usual % \cs{textit} and \cs{textbf} commands. % % TODO: add explanation for how to find out what the `font name' is. % % % \subsection{By file name} % \label{sec:by-file-name} % % \XeTeX\ and \LuaTeX\ also allow fonts to be loaded by file name instead of font name. % When you have a very large collection of fonts, you will sometimes not % wish to have them all installed in your system's font directories. % In this case, it is more convenient to load them from a different location on your disk. % This technique is also necessary in \XeTeX\ when loading OpenType fonts that are present within your \TeX\ distribution, such as \path{/usr/local/texlive/2010/texmf-dist/fonts/opentype/public}. % Fonts in such locations are visible to \XeTeX\ but cannot be loaded by font name, only file name; \LuaTeX\ does not have this restriction. % % When selecting fonts by file name, any font that can be found in the default % search paths may be used directly (including in the current directory) % without having to explicitly define the location of the font file on disk. % % \paragraph{\XeTeX\ \& Mac users only:} % Note that \XeTeX\ can only select fonts in this way with the |xdvipdfmx| driver, but \XeTeX\ with the |xdv2pdf| driver can only select system-installed fonts % by font name and not file name. The |xdvipdfmx| driver is default for \XeTeX, so this is only a problem if you wish to explicitly use % the |xdv2pdf| driver. % % Fonts selected by filename must include bold and italic variants explicitly. % \begin{Verbatim} % \fontspec % [ BoldFont = texgyrepagella-bold.otf , % ItalicFont = texgyrepagella-italic.otf , % BoldItalicFont = texgyrepagella-bolditalic.otf ] % {texgyrepagella-regular.otf} % \end{Verbatim} % \pkg{fontspec} knows that the font is to be selected by file name by the % presence of the `|.otf|' extension. % An alternative is to specify the extension separately, as shown following: % \begin{Verbatim} % \fontspec % [ Extension = .otf , % BoldFont = texgyrepagella-bold , % ... ] % {texgyrepagella-regular} % \end{Verbatim} % If desired, an abbreviation can be applied to the font names based on the % mandatory `font name' argument: % \begin{Verbatim} % \fontspec % [ Extension = .otf , % UprightFont = *-regular , % BoldFont = *-bold , % ... ] % {texgyrepagella} % \end{Verbatim} % In this case `texgyrepagella' is no longer the name of an actual font, % but is used to construct the font names for each shape; % the |*| is replaced by `texgyrepagella'. % Note in this case that |UprightFont| is required for constructing the font % name of the normal font to use. % % To load a font that is not in one of the default search paths, its location % in the filesystem must be specified with the |Path| feature: % \begin{Verbatim} % \fontspec % [ Path = /Users/will/Fonts/ , % UprightFont = *-regular , % BoldFont = *-bold , % ... ] % {texgyrepagella} % \end{Verbatim} % Note that \XeTeX\ and \LuaTeX\ are able to load the font without giving an % extension, but \pkg{fontspec} must know to search for the file; this can can % be indicated by declaring the font exists in an `|ExternalLocation|': % \begin{Verbatim} % \fontspec % [ ExternalLocation , % BoldFont = texgyrepagella-bold , % ... ] % {texgyrepagella-regular} % \end{Verbatim} % To be honest, |Path| and |ExternalLocation| are actually the same feature % with different names. The former can be given without an argument and the % latter can be given with one; the different names are just for clarity. % % % \section{Default font families} % \label{sec:setxxfont} % % \cmdbox{ % \cmd{\setmainfont} \oarg{font features} \marg{font name} \\ % \cmd{\setsansfont} \oarg{font features} \marg{font name} \\ % \cmd{\setmonofont} \oarg{font features} \marg{font name} % } % % These commands are used to select % the default font families for the entire document. They take the % same arguments as \cmd{\fontspec}. See \exref{fontload}. % Here, the scales of the fonts have been chosen to equalise their % lowercase letter heights. The \feat{Scale} font feature will be discussed % further in \vref{sec:font-ind-features}, including methods for automatic % scaling. % % \begin{Lexample}{fontload}{Loading the default, sans serif, and monospaced fonts.} % \setmainfont{TeX Gyre Bonum} % \setsansfont[Scale=MatchLowercase]{Latin Modern Sans} % \setmonofont[Scale=MatchLowercase]{Inconsolata} % % \rmfamily Pack my box with five dozen liquor jugs\par % \sffamily Pack my box with five dozen liquor jugs\par % \ttfamily Pack my box with five dozen liquor jugs % \end{Lexample} % % % % % \section{New commands to select font families} % % \cmdbox{ % \CMD{\string\newfontfamily} \cs{\meta{font-switch}} \oarg{font features} \marg{font name} \\ % \CMD{\string\newfontface} \cs{\meta{font-switch}} \oarg{font features} \marg{font name} % } % % \noindent For cases when a specific font with a specific % feature set is going to be re-used many times in a document, it is inefficient % to keep calling \cs{fontspec} for every use. While the \cs{fontspec} command does not define % a new font instance after the first call, the feature options must still be % parsed and processed. % % \DescribeMacro{\newfontfamily} % For this reason, new commands can be created for loading a particular font % family with the \cmd\newfontfamily\ command, demonstrated in \exref{nff}. % This macro should be used to create commands that would be used in % the same way as \cmd\rmfamily, for example. % If you would like to create a command that only changes the font % inside its argument (i.e., the same behaviour as \cs{emph}) define it using regular \LaTeX\ % commands: % \begin{Verbatim} % \newcommand\textnote[1]{{\notefont #1}} % \textnote{This is a note.} % \end{Verbatim} % Note that the double braces are intentional; the inner pair are used to % to delimit the scope of the font change. % % \begin{Lexample}{nff}{Defining new font families.} % \newfontfamily\notefont{Kurier} % \notefont This is a \emph{note}. % \end{Lexample} % % \DescribeMacro{\newfontface} % Sometimes only a specific font face is desired, without accompanying italic or bold variants % being automatically selected. % This is common when selecting a fancy italic font, say, that has swash features unavailable % in the upright forms. \cmd\newfontface\ is used for this purpose, shown % in \exref{nfface}, which is repeated in \vref{sec:contextuals}. % % \begin{Xexample}{nfface}{Defining a single font face.} % \newfontface\fancy % [Contextuals={WordInitial,WordFinal}] % {Hoefler Text Italic} % \fancy where is all the vegemite % % \emph, \textbf, etc., all don't work % \end{Xexample} % % Comment for advanced users: % The commands defined by \cs{newfontface} and \cs{newfontfamily} include % their encoding information, so even if the document is set to use a % legacy \TeX\ encoding, such commands will still work correctly. For example, % \begin{Verbatim} % \documentclass{article} % \usepackage{fontspec} % \newfontfamily\unicodefont{Lucida Grande} % \usepackage{mathpazo} % \usepackage[T1]{fontenc} % \begin{document} % A legacy \TeX\ font. {\unicodefont A unicode font.} % \end{document} % \end{Verbatim} % % \subsection{More control over font shape selection} % \label{sec:bfitfonts} % % \cmdbox{ % \feat{BoldFont} = \meta{font name} \\ % \feat{ItalicFont} = \meta{font name} \\ % \feat{~BoldItalicFont} = \meta{font name} \\ % \feat{SlantedFont} = \meta{font name} \\ % \feat{BoldSlantedFont} = \meta{font name} \\ % \feat{SmallCapsFont} = \meta{font name} % } % % The automatic bold, italic, and bold italic font selections will not be % adequate for the needs of every font: while some fonts mayn't even % have bold or italic shapes, in which case a skilled (or lucky) % designer may be able to chose well-matching accompanying shapes from % a different font altogether, others can have a range of bold and % italic fonts to chose among. The \feat{BoldFont} and % \feat{ItalicFont} features are provided for these situations. If only % one of these is used, the bold italic font is requested as the % default from the \emph{new} font. See \exref{bff}. % % \begin{Xexample}{bff}{Explicit selection of the bold font.} % \fontspec[BoldFont={Helvetica Neue}] % {Helvetica Neue UltraLight} % Helvetica Neue UltraLight \\ % {\itshape Helvetica Neue UltraLight Italic} \\ % {\bfseries Helvetica Neue } \\ % {\bfseries\itshape Helvetica Neue Italic} \\ % \end{Xexample} % % If a bold italic shape is not defined, or you want to specify % \emph{both} custom bold and italic shapes, the \feat{BoldItalicFont} % feature is provided. % % \subsubsection{Input shorthands} % % For those cases that the base font name is repeated, you can % replace it with an asterisk. (This has been shown previously in \vref{sec:by-file-name}.) % For example, % some space can be saved instead of writing `\texttt{Baskerville SemiBold}': % \begin{Verbatim} % \fontspec[BoldFont={* SemiBold}]{Baskerville} % \end{Verbatim} % % As a matter of fact, this feature can also be used for the upright font too: % \begin{Verbatim} % \fontspec[UprightFont={* SemiBold}, % BoldFont={* Bold}]{Baskerville} % \end{Verbatim} % % \subsubsection{Small caps and slanted font shapes} % % For the rare situations where a font family will have slanted \emph{and} % italic shapes, these may be specified separately using the analogous % features \feat{SlantedFont} and \feat{BoldSlantedFont}. Without these, % however, the \LaTeX\ font switches for slanted (\cs{textsl}, \cs{slshape}) % will default to the italic shape. % % Old-fashioned font families used to distribute their small caps % glyphs in separate fonts due to the limitations on the number % of glyphs allowed in the PostScript Type~1 format. Such fonts may be used % by declaring the \feat{SmallCapsFont} of the family you are specifying: % \begin{Verbatim} % \fontspec[ % SmallCapsFont={Minion MM Small Caps & Oldstyle Figures} % ]{Minion MM Roman} % Roman 123 \\ \textsc{Small caps 456} % \end{Verbatim} % In fact, you may specify the small caps font for each individual bold and % italic shape as in % \begin{Verbatim} % \fontspec[ % UprightFeatures = { SmallCapsFont={ } } , % BoldFeatures = { SmallCapsFont={ } } , % ItalicFeatures = { SmallCapsFont={ } } , % BoldItalicFeatures = { SmallCapsFont={ } } , % ]{ } % Roman 123 \\ \textsc{Small caps 456} % \end{Verbatim} % % For most modern fonts that have small caps as a font feature, this level of % control isn't generally necessary, but you may still occasionally find font % families in which the small caps are in a separate font. % % All of the bold, italic, and small caps fonts can be loaded with different % font features from the main font. See \ref{sec:bfit-feat} for details. % When an OpenType font is selected for |SmallCapsFont|, the small caps % font feature is \emph{not} automatically enabled. In this case, users % should write instead % \begin{Verbatim} % \fontspec[ % SmallCapsFont={...}, % SmallCapsFeatures={Letters=SmallCaps}, % ]{...} % \end{Verbatim} % % \subsection{Math(s) fonts} % % When \cmd\setmainfont, \cmd\setsansfont\ and \cmd\setmonofont\ are used in the % preamble, they also define the fonts to be used in maths mode inside the % \cmd\mathrm-type commands. This only occurs in the preamble because \LaTeX\ % freezes the maths fonts after this stage of the processing. The \pkg{fontspec} % package must also be loaded after any maths font packages (\eg, \pkg{euler}) % to be successful. (Actually, it is \emph{only} \pkg{euler} that is the % problem.\note{Speaking of \pkg{euler}, if you want to use its % \texttt{[mathbf]} option, it won't work, and you'll need to put this after % \pkg{fontspec} is loaded instead: % \ttfamily\cmd\AtBeginDocument\char`\{\cmd\DeclareMathAlphabet\cmd\mathbf\char`\{U\char`\}\char`\{eur\char`\}\char`\{b\char`\}\char`\{n\char`\}}) % % Note that \pkg{fontspec} will not change the font for general mathematics; % only the upright and bold shapes will be affected. % To change the font used for the mathematical symbols, see either the % \pkg{mathspec} package or the \pkg{unicode-math} package. % % Note that you may find that loading some maths packages won't be as smooth as % you expect since \pkg{fontspec} (and \XeTeX\ in general) breaks many of the % assumptions of \TeX\ as to where maths characters and accents can be found. % Contact me if you have troubles, but I can't guarantee to be able to fix any % incompatibilities. The Lucida and Euler maths fonts should be fine; for all % others keep an eye out for problems. % % \cmdbox{ % \cmd{\setmathrm} \oarg{font features} \marg{font name} \\ % \cmd{\setmathsf} \oarg{font features} \marg{font name} \\ % \cmd{\setmathtt} \oarg{font features} \marg{font name} \\ % \cmd{\setboldmathrm} \oarg{font features} \marg{font name} % } % % However, the default text fonts may not necessarily be the ones you % wish to use when typesetting maths (especially with the use of fancy % ligatures and so on). For this reason, you may optionally use the % commands above (in the same way as our other % \cmd\fontspec-like commands) to explicitly state which fonts to use % inside such commands as \cmd\mathrm. Additionally, the % \cmd\setboldmathrm\ command allows you define the font used for % \cmd\mathrm\ when in bold maths mode (which is activated with, among % others, \cmd\boldmath). % % For example, if you were using Optima with the Euler maths font, you % might have this in your preamble: % \begin{Verbatim} % \usepackage{mathpazo} % \usepackage{fontspec,xunicode} % \setmainfont{Optima} % \setmathrm{Optima} % \setboldmathrm[BoldFont={Optima ExtraBlack}]{Optima Bold} % \end{Verbatim} % % % \subsection{Miscellaneous font selecting details} % % \paragraph{Spaces} % \cmd\fontspec\ and \cmd\addfontfeatures\ ignore trailing spaces as % if it were a `naked' control sequence; \eg, `|M. \fontspec{...} N|' and % `|M. \fontspec{...}N|' are the same. % % \paragraph{Italic small caps} % Note that this package redefines the \cs{itshape} and \cs{scshape} % commands in order to allow them to select italic small caps in % conjunction. % % \paragraph{Emphasis and nested emphasis} % You may specify the behaviour of the \cs{emph} command by setting the % \cs{emshape} command. \Eg, for bold emphasis:\par % \indent|\renewcommand\emshape{\bfseries}|\par\noindent % Nested emphasis is controlled by the \cs{eminnershape} command. % For example, for |\emph{\emph{...}}| to produce small caps:\par % \indent|\renewcommand\eminnershape{\scshape}|\par\noindent % % % % % % \section{Selecting font features} % \label{sec:selectingfeature} % % The commands discussed so far such as \cs{fontspec} each take an optional argument for % accessing the font features of the requested font. % Commands are provided to set default features to be applied for all fonts, and even to change the features that a font is presently loaded with. % Different font shapes can be loaded with separate features, and different features can even be selected for different sizes that the font appears in. % This section discusses these options. % % \subsection{Default settings} \label{sec:defaults} % % \cmdbox{\cmd\defaultfontfeatures \marg{font features}} % % It is desirable to define % options that are applied to every subsequent font selection command: % a default feature set, so to speak. This may be defined with the % \cmd{\defaultfontfeatures} command, shown in \exref{dff}. % New calls of \cs{defaultfontfeatures} overwrite previous ones. % % \begin{Xexample}{dff}{A demonstration of the \cs{defaultfontfeatures} command.} % \fontspec{TeX Gyre Adventor} % Some default text 0123456789 \\ % \defaultfontfeatures{ % Numbers=OldStyle, Color=888888 % } % \fontspec{TeX Gyre Adventor} % Now grey, with old-style figures: % 0123456789 % \end{Xexample} % % \subsection{Changing the currently selected features} % \label{sec:addfontfeatures} % % \cmdbox{\cmd\addfontfeatures \marg{font features}} % % This command allows font features to % be changed without knowing what features are currently selected or even what % font is being used.

The four-letter codes are given below along with the \pkg{fontspec} names for various features, for the benefit of people who are already familiar with OpenType. You can ignore the codes if they don't mean anything to you. % % % \subsection{How to select font features} % % Font features are selected by a series of \meta{feature}=\meta{option} % selections. Features are (usually) grouped logically; for example, all % font features relating to ligatures are accessed by writing \verb|Ligatures={...}| with the appropriate argument(s), which could be \texttt{TeX}, \texttt{Rare}, etc., as shown below in \ref{sec:ot-feat-liga}. % % Multiple options may be given to % any feature that accepts non-numerical input, although doing so will % not always work. Some options will override others in generally % obvious ways; \Verb|Numbers={OldStyle,Lining}| doesn't make much % sense because the two options are mutually exclusive, and \XeTeX\ % will simply use the last option that is specified (in this case % using \opt{Lining} over \opt{OldStyle}). % % If a feature or an option is requested that the font does not have, % a warning is given in the console output. As mentioned in \vref{sec:quiet-warnings} % these warnings can be suppressed by selecting the \texttt{[quiet]} package option. % % \section{Complete listing of OpenType font features} % \label{sec:ot-feat} % % \subsection{Ligatures} % \label{sec:ot-feat-liga} % % \feat{Ligatures} refer to the replacement of two separate characters % with a specially drawn glyph for functional or \ae sthetic reasons. % The list of options, of which multiple may be selected at one time, % is shown in \ref{feat:Ligatures}. % A demonstration with the Linux Libertine fonts\note{\url{http://www.linuxlibertine.org/}} is shown in \exref{lig}. % % Note the additional features accessed with \verb|Ligatures=TeX|. These are % not actually real OpenType features, but additions provided by \pkg{luaotfload} (i.e., \LuaTeX\ only) to emulate \TeX's behaviour for \textsc{ascii} input of curly quotes and punctuation.

These correspond to the OpenType features |cv01| to |cv99|. % % For each character that can be varied, it is possible to select among % possible options for that particular glyph. % For example, in \exref{cv} a variety of glyphs for the character `v' are % selected, in which |5| corresponds to the character `v' for this font feature, % and the trailing |:|\meta{n} corresponds to which variety to choose. % Georg Duffner's open source Garamond revival font\footnote{\url{http://www.georgduffner.at/ebgaramond/}} is used in this example. % Character variants are specifically designed not to conflict with each % other, so you can enable them individually per character as shown in % \exref{cv2}.

font feature file is a plain text file describing OpenType layout % feature of a font in a human-readable format. The syntax of OpenType feature % files is defined by Adobe\note{\url{http://www.adobe.com/devnet/opentype/afdko/topic_feature_file_syntax.html}}. % % Feature files can be used to add or customize OpenType features of a font on % the fly without editing the font file itself. % % Adding a new OpenType feature is as creating a plain text file defining % the new feature and then loading it by passing its name or path to % \feat{FeatureFile}, then OpenType features defined in the file can be % activated as usual. % % For example, when adding one of the default features like \texttt{kern} % or \texttt{liga}, no special activation is needed. On the other hand, % an optional feature like \texttt{onum} or \texttt{smcp} will be % activated when old style numbers or small capitals are activated, % respectively. However, OpenType feature in the feature file can have any % and that can be used to selectively activate the feature; for example % defining a ligature feature called \texttt{mlig} and then activating it % using \feat{RawFeature} option without activating other ligatures in the % font. % % Figure~\ref{fig:featurefile} shows an example feature file. The first two % lines set the script and language under which the defined features will be % available, which the default language in both default and Latin scripts, % respectively. % % Then it defines a \texttt{liga} feature, which is a glyph substitution % feature. The names starting with backslash are glyph names that is to be % substituted and while the leading backslash is optional, it is used to % escape glyph names when they interfere with preserved keywords. It should % also be noted that glyph names are font specific and the same glyph can be % named differently in different fonts. % % Glyph positioning features like kerning can be defined in a similar way, % but instead of the keyword \texttt{sub(stitute)} the keyword % \texttt{pos(ition)} is used instead. Figure~\ref{fig:featurefile} shows % an example of adding kerning between \texttt{AY} and \texttt{ay}\note{ % The kerning is expressed in font design units which are fractions of em % depending on the \emph{units per em} value of the font, usually 1000 for % PostScript fonts and 2048 for TrueType fonts.}. % % Lines starting with \verb|#| are comments and will be ignored. % % An OpenType feature file can have any number of features and can have a % mix of substitution and positioning features, please refer to the full % feature file specification for further documentation. % % \begin{figure} % \caption{An example font feature file.} % \label{fig:featurefile} % \hrule % \begin{Verbatim} % languagesystem DFLT dflt; % languagesystem latn dflt; % % # Ligatures % feature liga { % sub \f \i by \fi; % sub \f \l by \fl; % } liga; % % # Kerning % feature kern { % pos \A \Y -200; % pos \a \y -80; % } kern; % \end{Verbatim} % \hrule % \end{figure} % % \part{Fonts and features with \XeTeX} % \label{sec:xetex-features} % % % % % \section{\XeTeX-only font features} % % The features described here are available for any font % selected by \pkg{fontspec}. % % \subsection{Mapping} % \label{sec:mapping} % % \feat{Mapping} enables a \XeTeX\ text-mapping scheme, shown in \exref{mapping}. % % \begin{Xexample}{mapping}{\XeTeX's \feat{Mapping} feature.} % \fontspec[Mapping=tex-text]{Cochin} % ``!`A small amount of---text!'' % \end{Xexample} % % Using the |tex-text| mapping is also equivalent to writing |Ligatures=TeX|. % The use of the latter syntax is recommended for better compatibility with % \LuaTeX\ documents. % % % \subsection{Letter spacing} % Letter spacing, or tracking, is the term given to adding (or subtracting) a small amount of horizontal space in between adjacent characters. It is specified with the \feat{LetterSpace}, which takes a numeric argument, % shown in \exref{tracking}. % % The letter spacing parameter is a normalised additive factor (not a scaling factor); it is defined as a percentage of the font size. That is, for a 10\,pt font, a letter spacing parameter of `|1.0|' will add 0.1\,pt between each letter. % % \begin{Xexample}{tracking}{The \feat{LetterSpace} feature.} % \fontspec{Didot} % \addfontfeature{LetterSpace=0.0} % USE TRACKING FOR DISPLAY CAPS TEXT \\ % \addfontfeature{LetterSpace=2.0} % USE TRACKING FOR DISPLAY CAPS TEXT % \end{Xexample} % % This functionality \emph{should not be used for lowercase text}, which is spacing correctly to begin with, but it can be very useful, in small amounts, when setting small caps or all caps titles. % Also see the OpenType \opt{Uppercase} % option of the \feat{Letters} feature (\vref*{sec:letters}). % % \subsection{Different font technologies: \AAT\ and \ICU}\label{sec:renderer} % % \XeTeX\ supports two rendering technologies for typesetting, selected with % the \feat{Renderer} font feature. The first, \opt{AAT}, is % that provided (only) by \MacOSX\ itself. The second, \opt{ICU}, % is an open source OpenType interpreter. It provides much greater support for % OpenType features, notably contextual arrangement, over \opt{AAT}. % % In general, this feature will not need to be explicitly called: for OpenType % fonts, the \opt{ICU} renderer is used automatically, and for \AAT\ fonts, % \opt{AAT} is chosen by default. Some fonts, however, will contain font tables % for \emph{both} rendering technologies, such as the Hiragino Japanese fonts % distributed with \MacOSX, and in these cases the choice may be required. % % Among some other font features only available through a specific renderer, % \opt{ICU} provides for the \feat{Script} and \feat{Language} features, which allow % different font behaviour for different alphabets and languages; see \vref{sec:ot} % for the description of these features. {\em Because these font features can % change which features are able to be selected for the font instance, they are selected % by \pkg{fontspec} before all others and will automatically and without warning % select the \opt{ICU} renderer.} % % % \subsection{Optical font sizes} \label{sec:aat-opticalsize} % % Multiple Master fonts are parameterised over % orthogonal font axes, allowing continuous selection along such % features as weight, width, and optical size~(see \vref{sec:mm} for % further details). Whereas an OpenType font will have only a few separate % optical sizes, a Multiple Master font's optical size can be % specified over a continuous range. Unfortunately, this flexibility makes % it harder to create an automatic interface through \LaTeX, and the % optical size for a Multiple Master font must always be specified % explicitly. % \begin{Verbatim} % \fontspec[OpticalSize=11]{Minion MM Roman} % MM optical size test \\ % \fontspec[OpticalSize=47]{Minion MM Roman} % MM optical size test \\ % \fontspec[OpticalSize=71]{Minion MM Roman} % MM optical size test \\ % \end{Verbatim} % % % % % \section{\MacOSX's \AAT\ fonts} % \label{sec:aat-features} % % \MacOSX's font technology began life before the ubiquitous-OpenType era % and revolved around the Apple-invented `\AAT' font format. This format % had some advantages (and other disadvantages) but it never became widely % popular in the font world. % % Nonetheless, this is the font format that was first supported by \XeTeX\ % (due to its pedigree on \MacOSX\ in the first place) and was the first % font format supported by \pkg{fontspec}. A number of fonts distributed with % \MacOSX\ are still in the \AAT\ format, such as `Skia'. Documents % that use these fonts should be compiled with \XeLaTeX\ using the % \texttt{xdv2pdf} driver, as opposed to the default \texttt{xdvipdfmx}. E.g., % \begin{Verbatim} % xelatex -output-driver="xdv2pdf" filename.tex % \end{Verbatim} % % \MacOSX\ also supports Multiple Master fonts, which are discussed % in \ref{sec:mm}. % % \subsection{Ligatures} % % \feat{Ligatures} refer to the replacement of two separate characters % with a specially drawn glyph for functional or \ae sthetic reasons. % For \AAT\ fonts, you may choose from any combination of \opt{Required}, % \opt{Common}, \opt{Rare} (or \opt{Discretionary}), \opt{Logos}, \opt{Rebus}, % \opt{Diphthong}, \opt{Squared}, \opt{AbbrevSquared}, and \opt{Icelandic}. % % Some other Apple \AAT\ fonts have those `Rare' ligatures contained in % the \opt{Icelandic} feature. Notice also that the old \TeX\ trick of % splitting up a ligature with an empty brace pair does not work in % \XeTeX; you must use a 0\,pt kern or \cs{hbox} (\eg, \cs{null}) to % split the characters up if you do not want a ligature to be performed (the usual examples for when this might be desired are words like `shelf\null full'). % % \subsection{Letters} \label{sec:aat-letters} % The \opt{Letters} feature specifies how the letters in the current font % will look. For \AAT\ fonts, you may choose from \opt{Normal}, % \opt{Uppercase}, \opt{Lowercase}, \opt{SmallCaps}, and % \opt{InitialCaps}. % % % \subsection{Numbers} % The \feat{Numbers} feature defines how numbers will look in the % selected font. For \AAT\ fonts, they may be a % combination of \opt{Lining} or \opt{OldStyle} and \opt{Proportional} or % \opt{Monospaced} (the latter is good for tabular material). The synonyms % \opt{Uppercase} and \opt{Lowercase} are equivalent to \opt{Lining} and % \opt{OldStyle}, respectively. The differences have been shown previously % in \vref{sec:addfontfeatures}. % % \subsection{Contextuals} \label{sec:contextuals} % This feature refers to glyph substitution that vary by their position; % things like contextual swashes are implemented here. % The options for \AAT\ fonts are % \opt{WordInitial}, \opt{WordFinal} (\exref{wordcx}), \opt{LineInitial}, % \opt{LineFinal}, and \opt{Inner} (\exref{longsaat}, also called `non-final' sometimes). As % non-exclusive selectors, like the ligatures, you can turn them off % by prefixing their name with \opt{No}. % % \begin{Xexample}{wordcx}{Contextual glyph for the beginnings and ends of words.} % \newfontface\fancy % [Contextuals={WordInitial,WordFinal}] % {Hoefler Text Italic} % \fancy where is all the vegemite % \end{Xexample} % % \begin{Xexample}{longsaat}{A contextual feature for the `long s' can be convenient as the character does not need to be marked up explicitly.} % \fontspec[Contextuals=Inner]{Hoefler Text} % `Inner' swashes can \emph{sometimes} \\ % contain the archaic long~s. % \end{Xexample} % % % % \subsection{Vertical position} % The \feat{VerticalPosition} feature is used to access things like % subscript (\opt{Inferior}) and superscript (\opt{Superior}) numbers and % letters (and a small amount of punctuation, sometimes). % The \opt{Ordinal} option is (supposed to be) % contextually sensitive to only raise characters that appear directly % after a number. % These are shown in \exref{aat-supp}. % % \begin{Xexample}{aat-supp}{Vertical position for AAT fonts.} % \fontspec{Skia} % Normal % \fontspec[VerticalPosition=Superior]{Skia} % Superior % \fontspec[VerticalPosition=Inferior]{Skia} % Inferior \\ % \fontspec[VerticalPosition=Ordinal]{Skia} % 1st 2nd 3rd 4th 0th 8abcde % \end{Xexample} % % The \pkg{realscripts} package % (also loaded by \pkg{xltxtra}) % redefines the \cmd\textsubscript\ and % \cmd\textsuperscript\ commands to use the above font features, % including for use in footnote labels. % % \subsection{Fractions} % Many fonts come with the capability to typeset various forms of % fractional material. This is accessed in \pkg{fontspec} with the % \feat{Fractions} feature, which may be turned \opt{On} or \opt{Off} % in both \AAT\ and OpenType fonts. % % In \AAT\ fonts, the `fraction slash' or solidus character, is % to be used to create fractions. When \feat{Fractions} are turned % \opt{On}, then only pre-drawn fractions will be used. % See \exref{aat-frac}. % % Using the \opt{Diagonal} option (\AAT\ only), the font will attempt % to create the fraction from superscript and subscript % characters. % % \edef\caretcc{\the\catcode`\^} % \catcode`\^=12\relax % \begin{Xexample}{aat-frac}{Fractions in AAT fonts.

Some fonts will contain many alternate % glyphs in order to be able to display these gylphs % correctly in whichever form is appropriate. Both \AAT\ and OpenType % fonts support the following \feat{CJKShape} options: % \opt{Traditional}, \opt{Simplified}, \opt{JIS1978}, \opt{JIS1983}, % \opt{JIS1990}, and \opt{Expert}. OpenType also supports the \opt{NLC} option. % % \subsection{Character width} % See \vref{sec:CharacterWidth} for relevant examples; the features are % the same between OpenType and \AAT\ fonts. % \AAT\ also allows \feat{CharacterWidth}|=|\opt{Default} to return to % the original font settings. % % % % % % \subsection{Vertical typesetting} % % TODO: improve! % % \XeTeX\ provides for vertical typesetting simply with the ability to rotate % the individual glyphs as a font is used for typesetting, as shown in % \exref{vert}. % % \begin{Xexample}[firstline=2]{vert}{Vertical typesetting.} % \def\verttext{共産主義者は} % \fontspec{Hiragino Mincho Pro} % \verttext % % \fontspec[Renderer=AAT,Vertical=RotatedGlyphs]{Hiragino Mincho Pro} % \rotatebox{-90}{\verttext}% requires the graphicx package % \end{Xexample} % % No actual provision is made for typesetting top-to-bottom % languages; for an example of how to do this, see the vertical Chinese % example provided in the \XeTeX\ documentation. % % % % % \subsection{Diacritics} % Diacritics are marks, such as the acute accent or the tilde, applied to letters; they usually indicate a change in pronunciation. % In Arabic scripts, diacritics are used to indicate vowels. % You may either choose % to \opt{Show}, \opt{Hide} or \opt{Decompose} them in \AAT\ fonts. % The \opt{Hide} option is for scripts such as Arabic which may be % displayed either with or without vowel markings. E.g., % \verb|\fontspec[Diacritics=Hide]{...}| % % Some older fonts distributed with \MacOSX\ included `|O/|' \etc\ as shorthand for writing `\O' under the label of the \feat{Diacritics} feature. If you come across such fonts, you'll % want to turn this feature off (imagine typing |hello/goodbye| and % getting `hell\o goodbye' instead!) by decomposing the two characters % in the diacritic into the ones you actually % want. I recommend using % the proper \LaTeX\ input conventions for obtaining such characters % instead. % % % % \subsection{Annotation} % Various Asian fonts are equipped with a more extensive range of % numbers and numerals in different forms. These are accessed through % the \feat{Annotation} feature (see \exref{aat-annot}) with the following % options: \opt{Off}, % \opt{Box}, \opt{RoundedBox}, \opt{Circle}, \opt{BlackCircle}, % \opt{Parenthesis}, \opt{Period}, \opt{RomanNumerals}, \opt{Diamond}, % \opt{BlackSquare}, \opt{BlackRoundSquare}, and \opt{DoubleCircle}. % % \begin{Xexample}{aat-annot}{Various annotation forms.} % \fontspec{Hei Regular} % 1 2 3 4 5 6 7 8 9 \\ % \fontspec[Annotation=Circle]{Hei Regular} % 1 2 3 4 5 6 7 8 9 \\ % \fontspec[Annotation=Parenthesis]{Hei Regular} % 1 2 3 4 5 6 7 8 9 \\ % \fontspec[Annotation=Period]{Hei Regular} % 1 2 3 4 5 6 7 8 9 % \end{Xexample} % % \section{\AAT\ \& Multiple Master font axes} \label{sec:mm} % % Multiple Master and \AAT\ font specifications both provide continuous % variation along font parameters. For example, they don't have just % regular and bold weights, they can have any bold weight you like between % the two extremes. % Note these features can only be used when your document is compiled using % the \verb|xdv2pdf| driver for Mac~OS~X. % % \opt{Weight}, \opt{Width}, and \opt{OpticalSize} are supported by this % package. Skia, which is distributed with % Mac~OS~X, has two of these variable parameters, allowing for the % demonstration in \exref{aatmm}. % Variations along a multiple master font's optical size axis has been % shown previously in \vref{sec:opticalsize}. % % \begin{Xexample}{aatmm}{Continuously variable font parameters. These fonts % are unfortunately quite rare.} % \fontspec[Weight=0.5,Width=3]{Skia} % Really light and extended Skia \\ % \fontspec[Weight=2,Width=0.5]{Skia} % Really fat and condensed Skia % \end{Xexample} % % % \part{Programming interface} % % This is the beginning of some work to provide some hooks that use % \pkg{fontspec} for various macro programming purposes. % % % \section{Defining new features} \label{sec:newfeatures} % This package cannot hope to contain every possible font % feature. Three commands are provided for selecting font features % that are not provided for out of the box. If you are using % them a lot, chances are I've left something out, so please let me % know. % % \DescribeMacro{\newAATfeature} % New \AAT\ features may be created with this command:\par % {\centering\cmd\newAATfeature\marg{feature}\marg{option}\marg{feature code}\marg{selector code}\par}\noindent % Use the \XeTeX\ file \path{AAT-info.tex} to obtain the code numbers. % See \exref{newAATfeat}. % % \begin{Xexample}{newAATfeat}{Assigning new \AAT\ features.} % \newAATfeature{Alternate}{HoeflerSwash}{17}{1} % \fontspec[Alternate=HoeflerSwash]{Hoefler Text Italic} % This is XeTeX by Jonathan Kew. % \end{Xexample} % % % \DescribeMacro{\newICUfeature} % \DescribeMacro{\newopentypefeature} % New OpenType features may be created with this command:\par % {\centering\cmd\newICUfeature\marg{feature}\marg{option}\marg{feature tag}\par} % The synonym \cs{newopentypefeature} is provided for \LuaLaTeX\ users. % % Here's what it would look like in practise: % \begin{Verbatim} % \newopentypefeature{Style}{NoLocalForms}{-locl} % \end{Verbatim} % % \DescribeMacro{\newfontfeature} % In case the above commands do not accommodate the desired font feature % (perhaps a new \XeTeX\ feature that \pkg{fontspec} hasn't been updated % to support), a command is provided to pass arbitrary input into the % font selection string:\par % {\centering\cmd{\newfontfeature}\marg{name}\marg{input string}\par} % % For example, Zapfino % contains the feature `Avoid d-collisions'.

By contrast, \cmd\newfontfeature\ will not give a warning % for improper input. % % \section{Going behind \pkg{fontspec}'s back} % Expert users may wish not to use \pkg{fontspec}'s feature handling at all, % while still taking advantage of its \LaTeX\ font selection conveniences. The % \feat{RawFeature} font feature allows literal \XeTeX\ font feature selection % when you happen to have the OpenType feature tag memorised. % % \begin{Xexample}{raw}{Using raw font features directly.} % \fontspec[RawFeature=+smcp]{TeX Gyre Pagella} % Pagella small caps % \end{Xexample} % % Multiple features can either be included in a single declaration:\par % {\centering|[RawFeature=+smcp;+onum]|\par} % \noindent or with multiple declarations:\par % {\centering|[RawFeature=+smcp, RawFeature=+onum]|\par} % % \section{Renaming existing features \& options} % \label{sec:aliasfontfeature} % % \DescribeMacro{\aliasfontfeature} % If you don't like the name of a particular font feature, % it may be aliased to another with the % \cs{aliasfontfeature}\marg{existing name}\marg{new name} command, % such as shown in \exref{alias}. % % \begin{Xexample}{alias}{Renaming font features.} % \aliasfontfeature{ItalicFeatures}{IF} % \fontspec[IF = {Alternate=1}]{Hoefler Text} % Roman Letters \itshape And Swash % \end{Xexample} % % Spaces in feature (and option names, see below) \emph{are} allowed.

That is, \opt{Proportional} can be aliased to \opt{Prop} in the % \feat{Letters} feature, but \opt{550099BB} cannot be substituted for \opt{Purple} % in a \feat{Color} specification. For this type of thing, the \cmd\newfontfeature\ % command should be used to declare a new, \eg, \feat{PurpleColor} feature: % \begin{Verbatim} % \newfontfeature{PurpleColor}{color=550099BB} % \end{Verbatim} % Except that this example was written before support for named colours was % implemented. But you get the idea. % % \section{Programming details} % % In some cases, it is useful to know what the \LaTeX\ font family % of a specific \pkg{fontspec} font is. After a \cmd\fontspec-like % command, this is stored inside the \cmd\l_fontspec_family_tl\ macro. % Otherwise, \LaTeX's own \cmd\f@family\ macro can be useful here, % too. % The raw \TeX\ font that is defined is stored temporarily % in \cmd{\l_fontspec_font}. % % The following commands in \pkg{expl3} syntax may be used % for writing codes that interface with fontspec-loaded fonts. % All of the following conditionals also exist with |T| and |F| % as well as |TF| suffixes. % % \begin{macro}{\fontspec_if_fontspec_font:TF} % Test whether the currently selected font has been loaded by fontspec. % \end{macro} % % % \begin{macro}{\fontspec_if_aat_feature:nnTF} % Test whether the currently selected font contains the \AAT\ % feature (|#1|,|#2|). % \end{macro} % % % \begin{macro}{\fontspec_if_opentype:TF} % Test whether the currently selected font is an OpenType font. % Always true for LuaTeX fonts. % \end{macro} % % \begin{macro}{\fontspec_if_feature:nTF} % Test whether the currently selected font contains the raw OpenType % feature |#1|.

Therefore, we use \LaTeX's NFSS % information, which is more likely to be correct. % % \section{Unicode footnote symbols} % By default \LaTeX\ defines symbolic footnote characters in terms of commands % that don't resolve well; better results can be achieved by using specific Unicode characters or proper LICRs with the \pkg{xunicode} package. % % This problem has been solved by loading the \pkg{fixltx2e} package. % % \section{Verbatim} % \label{sec:verb} % % Many verbatim mechanisms assume the existence of a `visible space' character that exists in the \textsc{ascii} space slot of the typewriter font. This character is known in Unicode as \unichar{2434}{box open}, which looks like this: `\verb*| |'. % % When a Unicode typewriter font is used, \LaTeX\ no longer prints visible spaces for the |verbatim*| environment and |\verb*| command. This problem is fixed by using the correct Unicode glyph, and the following packages are patched to do the same: % \pkg{listings}, \pkg{fancyvrb}, \pkg{moreverb}, and \pkg{verbatim}. % % In the case that the typewriter font does not contain `\verb*| |', the Latin Modern Mono font is used as a fallback. % % \section{Discretionary hyphenation: \cmd\-} % \label{sec:hyphen} % % \LaTeX\ defines the macro \cmd\-\ to insert discretionary hyphenation points. % However, it is hard-coded in \LaTeX\ to use the hyphen |-| character. Since \pkg{fontspec} % makes it easy to change the hyphenation character on a per font basis, it would % be nice if \cmd\-\ adjusted automatically --- and now it does. % % \section{Commands for old-style and lining numbers} % % \DescribeMacro{\oldstylenums} % \DescribeMacro{\liningnums} % \LaTeX's definition of \cs{oldstylenums} relies on strange font encodings. % We provide a \pkg{fontspec}-compatible alternative and while we're at it % also throw in the reverse option as well.

The basic command is {\centering \verb|\fontspec[font features]{font display name}|.\par} The default, sans serif, and typewriter fonts may be set with the \verb|\setmainfont|, \verb|\setsansfont| and \verb|\setmonofont| commands, respectively, as shown in the preamble. They take the same syntax as the \verb|\fontspec| package. All expected font shapes are available: \begin{center} {\itshape Italics and \scshape small caps\dots}\\ {\sffamily\bfseries Bold sans serif and \itshape bold italic sans serif\dots} \end{center} Text fonts in maths mode are also changed (e.g., notice the cosine function in `$\cos(n\pi)=\pm 1$') but only if the roman and sans serif fonts are set in the preamble; \verb|\setmainfont| will not affect these maths mode fonts when called mid-document. Maths symbols themselves are not affected. Notice the font features used to load the default fonts in the preamble. The first, \verb|Ligatures=TeX|, enables regular \TeX{} ligatures like \verb|``---''| for ``---''. The second, \verb|Scale=MatchLowercase|, automatically scales the fonts to the same x-height. Please see the complete \textsf{fontspec} documentation for further information. \end{document} % \end{macrocode} % % %<*testsuite> % % \begin{macrocode} \documentclass{article} \usepackage{fontspec,fancyvrb,geometry,graphicx,calc,multicol} \geometry{margin=2cm,a4paper} \setmainfont[Ligatures=TeX]{TeX Gyre Pagella} \setmonofont{Consolas} \newcommand\meta[1]{$\langle$\emph{#1}$\rangle$} \newcommand\TEST[1]{% \section{Test #1} \begin{minipage}{0.5\textwidth} \VerbatimInput{testsuite/#1.ltx} \end{minipage} \hfill \begin{minipage}{8cm+4pt} \fboxsep=1pt \fboxrule=1pt \fbox{\insertpdf#1\END} \end{minipage} } \def\insertpdf#1#2\END{% \ifnum`#1=70\relax \includegraphics[width=8cm]{testsuite/#1#2.Lsafe.pdf}% \else \includegraphics[width=8cm]{testsuite/#1#2.safe.pdf}% \fi } \newcommand\codeline[1]{\par{\centering#1\par}\par\noindent\ignorespaces} \pagestyle{empty} \begin{document} \title{The \textsf{fontspec} test suite} \author{Will Robertson} \date{Compiled: \today} \maketitle \thispagestyle{empty} \section*{Preamble} \begin{multicols}{2}\noindent The examples shown in the remainder of the document are generated directly from the code shown alongside. As well as being good minimal examples, these tests are useful to ensure that changes to \textsf{fontspec} don't affect old behaviour. When the test suite is run, the new output is compared pixel by pixel with that shown here and warnings produced if the outputs are not identical (within a small tolerance to account for rounding errors). Tests with a name that begins with `\textit X' are processed with \texttt{xelatex} only; `\textit L' with \texttt{lualatex}; and `\textit F' with both. In the latter case, the output from both engines is compared with each other, ensuring that the package is consistent cross-platform. To generate tests yourself, write a new file in the \texttt{testsuite/} folder with filename \codeline{\meta{F,L,X}\meta{num}\meta{letter}\texttt{.ltx}} according to the naming scheme above and the following numbering scheme. If you are writing a new test entirely, increment the \meta{num}; if you are writing a variation on an old test, increment the \meta{letter}. No need to be too fussy, though. After writing the new test, run \codeline{\texttt{make initest}} This will generate the reference output (\texttt{*.safe.pdf}) from which to check all future tests. After any changes have been made to \textsf{fontspec}, the entire test suite is compiled with \codeline{\texttt{make check}} If you want to run just a single test, use \codeline{\texttt{make }\meta{testname}} (but this syntax \emph{may} be fragile and need to be changed in the future). \end{multicols} \input{testsuite/testsuite-listing.tex} \end{document} % \end{macrocode} % % %<*doc-style> % \begin{macrocode} \ProvidesPackage{fontspec-style} \usepackage{booktabs,calc,caption,color,enumitem,fancyvrb,hologo,graphicx,ifthen,url,varioref,varwidth,microtype,tocloft} % ToC formatting: \setlength\cftsubsecnumwidth{1.4\cftsubsecnumwidth} \def\@cfttocstart{\begin{multicols}{2}} \def\@cfttocfinish{\end{multicols}} \fvset{gobble=2} \captionsetup[table]{position=above} \captionsetup[figure]{position=above} \newcommand\XeTeX{\hologo{XeTeX}} \newcommand\XeLaTeX{\hologo{XeLaTeX}} \newcommand\LuaTeX{\hologo{LuaTeX}} \newcommand\LuaLaTeX{\hologo{LuaLaTeX}} \usepackage{tgpagella,eulervm} \usepackage{inconsolata} \usepackage[ bookmarks=true, colorlinks=true, linkcolor=niceblue, urlcolor=niceblue, citecolor=niceblue, pdftitle={The fontspec package}, pdfsubject={Advanced font selection for XeLaTeX/LuaLaTeX}, pdfauthor={Will Robertson}, pdfkeywords={xetex, xelatex, luatex, lualatex, unicode, opentype, aat} ]{hyperref} %% ToC \def\@dotsep{1000} \setcounter{tocdepth}{2} \setlength\columnseprule{0.4pt} \renewcommand\tableofcontents{\relax \begin{multicols}{2}[\section*{\contentsname}]\relax \@starttoc{toc}\relax \end{multicols}} %% Index \setcounter{IndexColumns}{2} \renewenvironment{theglossary} {\small\list{}{} \item\relax \glossary@prologue\GlossaryParms \let\item\@idxitem \ignorespaces \def\pfill{\hspace*{\fill}}} {\endlist} %% varioref definitions: \labelformat{table}{Table~#1} \labelformat{section}{Section~#1} \labelformat{subsection}{Section~#1} \definecolor{niceblue}{rgb}{0.1,0.2,0.8} \newsavebox\X \newsavebox\Y \newcounter{example} \newcommand\exref[1]{Example~\ref{ex:#1}} \newcommand\Exref[1]{Example~\ref{ex:#1}} \newenvironment{Xexample}[3][] {\VerbatimEnvironment\begin{Fexample}[#1]{#2}{#3}{X}} {\end{Fexample}} \newenvironment{Lexample}[3][] {\VerbatimEnvironment\begin{Fexample}[#1]{#2}{#3}{L}} {\end{Fexample}} \newenvironment{Fexample}[4][] {% \def\options{#1}% \def\filename{#2}% \def\captiontext{#3}% \def\prefix{#4} \refstepcounter{example}% \label{ex:\filename}% \IfFileExists{doc-files/\theexample-\prefix-\filename.tex}{}{% \immediate\write18{cd doc-files && rm -f \theexample-* ;}% }% \VerbatimEnvironment \begin{VerbatimOut}{doc-files/\theexample-\prefix-\filename.tex}} % text in the environment {\end{VerbatimOut} \begin{figure} \setlength\parindent{0pt}% \edef\@tempa{[gobble=0,fontsize=\noexpand\small,\options]}% \savebox\X{% \expandafter\BVerbatimInput \@tempa{doc-files/\theexample-\prefix-\filename.tex}% }% \IfFileExists{doc-files/\theexample-\prefix-\filename.pdf}{} {% \edef\1{% cd doc-files;
