%   \noindent This package provides functionality for selecting families of
%   fonts with extended feature sets in \XeTeX-based \LaTeX.

%   fonts; \cmd\setromanfont\ sets the default for the whole
%   document, with analogous commands for \texttt{sans} and
%   \texttt{mono}. Other commands are provided for the advanced
%   selection of a large (and extensible) number of rich font features.

% \section{Introduction}
% With the introduction of \name{Jonathan Kew}'s
% \XeTeX,\footnote{\texttt{http://scripts.sil.org/xetex}} \MacOSX\
% users can now easily access system-wide fonts directly in a \TeX\
% variant, providing a best of both worlds environment. \XeTeX\
% eliminates the need for all those files required for installing
% fonts (|.tfm|, |.vf|, |.map|,\dots) and provides an easy
% way to select fonts in Plain \TeX: |\font\tenrm="Times New Roman" at 10pt|.
% 
% However, it was still necessary to write cumbersome font definition
% files for \LaTeX, since the NFSS had a lot more going on behind the
% scenes to allow easy commands like |\bfseries| and |\emph|.
%
% This package almost entirely eliminates this need by providing a
% completely automatic way to select font families in \LaTeX\ for
% arbitrary fonts. Furthermore, it allows (again, almost) total
% control over the selection of rich font features such as number case
% and fancy ligatures present in many modern fonts provided with
% \MacOSX.
%
% \subsection{Usage}
% There are no options for this package: simply call it in your
% preamble somewhere. As of \textsf{v1.6}, it is necessary to
% explicitly request \name{Ross Moore}'s \textsf{xunicode} package if
% you want access to use \LaTeX's various methods for accessing extra
% characters and accents (for example, |\textbullet|, |\"u|, |\O|, and
% so on).
%
% This is highly recommended, since macros such as |\%| will otherwise
% give you incorrect output. Note however that this will also break
% some characters in the default Computer Modern (or any other
% non-unicode encoded) fonts, but you're not using \XeTeX\ to use
% \emph{them}, are you!
% \begin{Verbatim}[gobble=4]
%   \usepackage{fontspec,xunicode}
% \end{Verbatim}
%
% \subsection{Warning}
% I still consider this package to be experimental, so I'm not
% ensuring backwards compatibility at all costs. I don't want to weigh
% the package down with old ways of doing things, so unfortunately
% this will mean that some old documents will need to be modified in
% order to compile correctly again. It'll be worth it in the long run,
% but you can curse at my lack of foresight as much as you wish in the
% meantime.
%
% Such things, and some other comments, are noted in the margin like
% this~\warn{v1.6}{An example warning!}, with a red arrow if the
% change is relevant to the current release of the package.
%
% \subsection{About this manual}
% This document has been typeset with \XeTeX\ using a variety of fonts
% to display various features that the package supports. You will not
% be able to typeset the documentation if you do not have all of these
% fonts, although I've used as many Mac~OS~X pre-installed fonts as
% possible. Running normal \LaTeX\ (\ie, with\emph{out} \XeTeX) on
% this file will generate the \texttt{fontspec.sty} file if this is
% required for some odd reason.
%
% Many examples are shown in this manual. These are typeset
% side-by-side with their verbatim source code, although various
% size-altering commands (\cs{large}, \cs{Huge}, \etc) are omitted for
% clarity. Since the package supports font features for both AAT and
% OpenType fonts (whose feature sets only overlap to some extent),
% examples are distinguished by colour: blue and red, respectively.
%
%
% \section{Font selection}
% \DescribeMacro{\fontspec} \cmd{\fontspec}\oarg{font
%   features}\marg{font name} is the base command of the package, used
% for selecting the specified \meta{font name} (which is the \MacOSX\
% display name of the font) in a \LaTeX\ family. We shall look at font
% features later. As an example, look how easy it is to select the
% Hoefler Text typeface:
% \begin{aatexample}
%   \def\pangram{The five boxing 
%                wizards jump quickly.}
%   \fontspec{Hoefler Text}
%                    \pangram       \\
%   {\itshape        \pangram  }    \\
%   {\scshape        \pangram  }    \\
%   {\itshape\scshape\pangram  }    \\
%    \bfseries       \pangram       \\
%   {\itshape        \pangram  }    \\
%   {\scshape        \pangram  }    \\
%   {\scshape\itshape\pangram  }
% \end{aatexample}
% The \pkg{fontspec} package takes care of the necessary font
% definitions for those shapes as shown above
% \emph{automatically}. Furthermore, it is not necessary to install
% the font for \XeTeX\ in any way whatsoever: every font that exists
% in one of \MacOSX's font folders may be accessed.
%
% Note that this package redefines the \cs{itshape} and \cs{scshape}
% commands in order to allow them to select italic small caps in
% conjunction.
%
% \subsection{Font instances for efficiency}
% 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 command does not
% define a new font instance after the first call, the feature options
% must still be parsed and processed.
%
% \DescribeMacro{\newfontinstance} For this reason, \emph{instances}
% of a font may be created with the \cs{newfontinstance} command, as
% shown in the following example:
% \begin{aatexample}
%   \newfontinstance\secfont[Letters=SmallCaps]{Hoefler Text}
%   \secfont Font instances for efficiency
% \end{aatexample}
%
% \subsection{Default font families}\label{sec:setxxfont}
% \DescribeMacro{\setromanfont} \DescribeMacro{\setsansfont}
% \DescribeMacro{\setmonofont} The \cs{setromanfont},
% \cs{setsansfont}, and \cs{setmonofont} commands are used to select
% the default font families for the entire document. They take the
% same arguments as \cmd{\fontspec}. For example:
% \begin{aatexample}
%   \def\pangram{Pack my box with five 
%                      dozen liquor jugs.}
%   \setromanfont{Baskerville}
%   \setsansfont[Scale=0.86]{Skia Regular}
%   \setmonofont[Scale=0.8]{Monaco}
%   \rmfamily\pangram\par
%   \sffamily\pangram\par
%   \ttfamily\pangram
% \end{aatexample}
% To match the families' sizes, you should use the \feat{Scale} feature with
% trial and error until the heights of the lowercase letters are
% equal. (Although there are more factors involved, this can often
% give a reasonable result.)
%
%
% \subsection{Arbitrary bold/italic fonts} \label{sec:bfitfonts} 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 between.  The \opt{BoldFont} and
% \opt{ItalicFont} options~\warn{v1.6}{These options used to be called
%   \opt{Bold} and \opt{Italic}, and these shorter names may still be
%   used if you desire.}  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.
% \begin{aatexample}
%   \fontspec[BoldFont={Helvetica Neue}]
%                           {Helvetica Neue UltraLight}
%                 Helvetica Neue UltraLight         \\
%   {\itshape     Helvetica Neue UltraLight Italic} \\
%   {\bfseries               Helvetica Neue       } \\
%   {\bfseries\itshape       Helvetica Neue Italic} \\
% \end{aatexample}
% If a bold italic shape is not defined, or you want to specify
% \emph{both} custom bold and italic shapes, the \opt{BoldItalicFont}
% option is provided~\warn{v1.6}{Yes, \opt{BoldItalic} also works}.
% \begin{aatexample}
%   \fontspec[BoldFont={Optima ExtraBlack}]{Optima Regular}
%                      Optima                            \\
%   {\itshape          Optima Italic               }     \\
%   {\bfseries         Optima ExtraBlack           }     \\
%   {\bfseries\itshape Optima ExtraBlack (italic?) }     \\
%   \addfontfeature{BoldItalic={Optima Bold Italic}}
%   {\bfseries\itshape Optima Bold Italic          }
% \end{aatexample}
% (The \cmd{\addfontfeature} command, used here for brevity, is
% described in \vref{sec:addfontfeatures}.)
%
%
% \subsection{Math(s) fonts}
%
% When \cmd\setromanfont, \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.)
%
% \DescribeMacro{\setmathrm} \DescribeMacro{\setboldmathrm}
% \DescribeMacro{\setmathsf} \DescribeMacro{\setmathtt} 
% 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 those
% commands listed in the margin (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[mathcal]{euler}
%   \usepackage{fontspec,xunicode}
%   \setromanfont{Optima Regular}
%   \setmathrm{Optima}
%   \setboldmathrm[BoldFont=Optima ExtraBlack]{Optima Bold}
% \end{verbatim}
% and this would allow you to typeset something like this:
% \begingroup
% \setromanfont{Optima Regular}
% \begin{aatexample}
%   $ X \rightarrow \mathrm{X} \rightarrow \mathbf{X} $
%   \\\boldmath
%   $ X \rightarrow \mathrm{X} \rightarrow \mathbf{X} $
% \end{aatexample}
% \endgroup
%
% \section{Selecting font features} \label{sec:selectingfeature} The
% commands discussed so far each take an optional argument for
% accessing the font features of the requested font.  These features
% are generally unavailable or harder to access in regular \LaTeX. The
% font features and their options are described in
% \vref{sec:features}, but there are, however, two other commands
% which may be used to affect font features, and they must be
% introduced first.
%
% \subsection{Default settings} \label{sec:defaults}
% \DescribeMacro{\defaultfontfeatures} 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}\marg{font features} command. This command
% is used, for example, to automatically colour all of the examples in
% this document. New calls of \cs{defaultfontfeatures} overwrite
% previous ones.
% \begin{aatexample}
%   \fontspec{Didot} 
%    Some `default' Didot 0123456789             \\
%   \defaultfontfeatures{Numbers=OldStyle, Colour=009900}
%   \fontspec{Didot}
%    Now green, with old-style figures: 0123456789
% \end{aatexample}
%
% \subsection{Changing the currently selected features}
% \label{sec:addfontfeatures}
% \DescribeMacro{\addfontfeatures} The \cs{addfontfeatures}\marg{font
%   features} command allows font features to be changed without
% knowing what features are currently selected or even what font is
% being used. A good example of this could be to add a hook to all
% tabular material to use monospaced numbers, as shown in the
% following example:
% \begin{aatexample}
%   \fontspec[Numbers=OldStyle]{Skia Regular}
%   `In 1842, 999 people sailed 97 miles in 
%    13 boats. In 1923, 111 people sailed 54
%    miles in 56 boats.'            \bigskip
%
%   \addfontfeatures{Numbers={Monospaced,Lining}}
%   \begin{tabular}{@{} cccc @{}}
%     \toprule  Year & People & Miles & Boats \\ 
%     \midrule  1842 &  999   &  75   &  13   \\ 
%               1923 &  111   &  54   &  56   \\
%     \bottomrule
%   \end{tabular}
% \end{aatexample}
% \DescribeMacro{\addfontfeature}
% This command may also be executed under the alias \cmd{\addfontfeature}.
%
% \subsection{Priority of feature selection}
% Features defined with \cs{addfontfeatures} override features
% specified by \cs{fontspec}, which in turn override features
% specified by \cs{defaultfontfeatures}.  If in doubt, whenever a
% new font is chosen for the first time, an entry is made in the
% transcript (\texttt{.log}) file displaying the font name and the
% features requested.
% 
%
% \section{Available font features} 
% \label{sec:features} 
% This section covers each and every font feature catered for by this
% package. Some, in fact, have already be seen in previous
% sections. There are too many to list in this introduction, but for a
% first taste of what is available, here is an example of the Apple
% Chancery typeface:
% \setexsize\Large
% \begin{aatexample}
%   \fontspec[
%     Colour=CC00CC,
%     Numbers=OldStyle,
%     VerticalPosition=Ordinal,
%     Variant=2]{Apple Chancery}
%   My 1st example of\\ Apple Chancery
% \end{aatexample}
% You can see that font features are accessed with a 
% \meta{feature}=\meta{option(s)} 
% interface.  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}).
%
%
% \subsection{Different features for different font shapes}
% It is entirely possible that separate fonts in a family will require
% separate options; \eg, Hoefler Text Italic contains various swash
% feature options that are completely unavailable in the upright shapes.
%
% Using the \opt{Bold-}, \opt{Italic-}, and \opt{BoldItalicFeatures}
% options, separate font features may be \emph{added} to those
% shapes. As a trivial example, let's colour each shape differently:
% \begin{aatexample}
%   \fontspec[
%      Numbers=Lining,
%      BoldFeatures={Colour=AA0000},
%      ItalicFeatures={Colour=008833},
%      BoldItalicFeatures={Colour=AA8833},
%            ]{Hoefler Text}
%                      0 -- Normal   \\
%   {\itshape          1 -- Italic}  \\
%   {\bfseries         2 -- Bold}    \\
%   {\bfseries\itshape 3 -- Bold Italic}
% \end{aatexample}
% Combined with the options for selecting arbitrary \emph{fonts} for
% the different shapes, these separate feature options allow the
% selection of arbitrary weights in (at least) the Skia typeface:
% \begin{aatexample}
%   \fontspec[BoldFont={Skia Regular},
%    BoldFeatures={Weight=2}]{Skia Regular}
%   Skia Regular \\ \bfseries Skia `Bold'
% \end{aatexample}
%
% \subsection{Font independent options}
%
% These features may be used with any font. \feat{Scale} takes a single
% numeric argument for scaling the font glyphs, and was demonstrated
% in \vref{sec:setxxfont}. \feat{Mapping} enables an \XeTeX\ text-mapping
% scheme.
% \begin{aatexample}
%   \fontspec[Mapping=tex-text]{Cochin}
%   ``!`A small amount of---text!''
% \end{aatexample}
% \feat{Colour} (or \feat{Color}), also shown in \vref{sec:defaults} and
% \vref{sec:features}, uses \XeTeX\ font specifications to set the colour of
% the font. The colour is defined as a triplet of two-digit Hex RGB
% values, with optionally another value for the transparency (where
% |00| is completely transparent and |FF| is opaque.)
% \begin{aatexample}
%   \fontsize{48}{48}
%   \fontspec{Hoefler Text Black}
%   {\addfontfeature{Color=FF000099}W}\kern-1ex
%   {\addfontfeature{Color=0000FF99}S}\kern-0.8ex
%   {\addfontfeature{Color=DDBB2299}P}\kern-0.8ex
%   {\addfontfeature{Color=00BB3399}R}
% \end{aatexample}
% \XeTeX\ has more advanced colour management abilities, but they
% cannot be accessed through this package (yet, if at all).
%
% \subsection{Optical font sizes} \label{sec:opticalsize}
% 
% Optically scaled fonts thicken out as the font size decreases
% in order to make the glyph shapes more robust (less prone to losing
% detail) which improves legibility. Conversely, at large optical
% sizes the serifs and other small details may be more delicately
% rendered. This is how type was set back in the day of lead and
% presses.
%
% Optically sized fonts can be seen in either OpenType or Multiple
% Master varieties. The differences when dealing with these two are
% quite significant. OpenType fonts with optical scaling will exist in
% several discrete sizes, and these will be selected by \XeTeX\
% \emph{automatically} determined by the current font size. The
% \opt{OpticalSize} option may be used to specify a different optical
% size.
%
% For the OpenType font Warnock Pro, we have three optically sized
% variants: caption, subhead, and display. With \opt{OpticalSize} set
% to zero, these are selected as with a regular font:
% \begin{opentypeexample}
%   \fontspec[OpticalSize=0]{Warnock Pro Caption}
%    Warnock Pro optical sizes                \\
%   \fontspec[OpticalSize=0]{Warnock Pro}        
%    Warnock Pro optical sizes                \\
%   \fontspec[OpticalSize=0]{Warnock Pro Subhead}
%    Warnock Pro optical sizes                \\
%   \fontspec[OpticalSize=0]{Warnock Pro Display}
%    Warnock Pro optical sizes
% \end{opentypeexample}
%
% Automatic OpenType optical scaling is shown in the following
% example, in which we've scaled down some large text in order to be
% able to compare the difference for equivalent font sizes: (this
% gives the same output as we saw in the previous example for Warnock
% Pro Display)
% \begin{opentypeexample}
%   \fontspec{Warnock Pro}
%    Automatic optical size                  \\
%   \scalebox{0.4}{\Huge 
%    Automatic optical size}
% \end{opentypeexample}
% 
% Multiple Master fonts, on the other hand, are parameterised over
% orthogonal font axes, allowing continuous selection along such
% features as weight, width, and optical size~(see \vref{sec:mm} for
% 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 large 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{aatexample}
%   \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{aatexample}
%
%
%
%
% \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}.
%
% The first three are also supported in OpenType fonts, which may also
% use \opt{Historical} and \opt{Contextual}. To turn a ligature option
% \emph{off}, prefix its name with \opt{No}: \eg, \opt{NoDiphthong}.
% \setexsize\Large
% \begin{aatexample}
%   \fontspec[Ligatures=Rare]{Hoefler Text}
%    strict firefly                         \\
%   \fontspec[Ligatures=NoCommon]{Hoefler Text}
%    strict firefly
% \end{aatexample}
% \setexsize\large
% \begin{aatexample}
%   \fontspec
%     [Ligatures={Rare,Logos,Rebus,Diphthong}]
%     {Palatino}
%   Rare: Dh Th dh th                \\
%   Logos: apple                     \\
%   Rebus: \%0                       \\
%   Dipht\null hong: AE OE ae oe 
% \end{aatexample}
% 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.
%
% \subsection{Letters}
% The \opt{Letters} feature~\warn{v1.6}{This feature has changed names
%   along with its options, \textbf{breaking} backwards
%   compatibility!}  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}.
% \begin{aatexample}
%   \fontspec[Letters=Uppercase]{Palatino}
%    THIS Sentence no verb             \\
%   \fontspec[Letters=Lowercase]{Palatino}
%    THIS Sentence no verb             \\
%   \fontspec[Letters=InitialCaps]{Palatino}
%    THIS Sentence no verb
% \end{aatexample}
% OpenType fonts have some different options:
% \opt{SmallCaps}, \opt{PetiteCaps}, \opt{SMALLCAPS}, \opt{PETITECAPS}, and
% \opt{Unicase}. Petite caps are smaller than small caps. Mixed case
% commands turn lowercase letters into the smaller caps letters,
% whereas uppercase options turn the capital letters to the smaller
% caps (good, \eg, for applying to already uppercase acronyms like
% `NASA'). Finally, unicase is a weird hybrid of upper and lower case
% letters.
% \begin{opentypeexample}
%   \fontspec[Letters=SmallCaps]{Warnock Pro}
%    THIS SENTENCE no verb                \\
%   \fontspec[Letters=SMALLCAPS]{Warnock Pro}
%    THIS SENTENCE no verb
% \end{opentypeexample}
%
%
% \subsection{Numbers} 
% The \feat{Numbers} feature defines how numbers will look in the
% selected font. For both AAT and OpenType 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}.
%
% For OpenType fonts, there is also the \opt{SlashedZero} option which
% replaces the default zero with a slashed version to prevent
% confusion with an uppercase `O'.
% \begin{opentypeexample}
%   \fontspec[Numbers=Lining]{Warnock Pro}
%    0123456789
%   \fontspec[Numbers=SlashedZero]{Warnock Pro}
%    0123456789
% \end{opentypeexample}
%
% \subsection{Swashes} 
% \feat{Swashes} are fancy ornaments on letters. The options for AAT are
% \opt{WordInitial}, \opt{WordFinal}, \opt{LineInitial},
% \opt{LineFinal}, and \opt{Inner} (also known as `non-final'). As
% non-exclusive selectors, like the ligatures, you can turn them off
% by prefixing their name with \opt{No}.
% \begin{aatexample}
%   \fontspec
%       [Swashes={WordInitial,WordFinal}]
%                        {Hoefler Text Italic}
%   where is all the vegemite
% \end{aatexample}
% \begin{aatexample}
%   \fontspec[Swashes=Inner]{Hoefler Text}
%   `Inner' swashes can \emph{sometimes}    \\
%    contain the archaic long~s.
% \end{aatexample} 
% For OpenType fonts, all but the \opt{LineInitial} and \opt{Inner} features
% are also supported, and \opt{Contextual} turns on contextual
% swashes.
% \begin{opentypeexample}
%   \fontspec{Warnock Pro}\itshape
%    Without Contextual Swashes             \\
%   \fontspec[Swashes=Contextual]{Warnock Pro}
%    With Contextual Swashes; cf. W C S
% \end{opentypeexample}
%
%
% \subsection{Diacritics}
% Diacritics refer to characters that include extra marks that usually
% indicate pronunciation; \eg, accented letters. You may either choose
% to \opt{Show}, \opt{Hide} or \opt{Decompose} them in AAT fonts.
%
% Some fonts include |O/| \etc\ as diacritics for writing \O. 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 would recommend using
% the proper \TeX\ input conventions for obtaining such characters
% instead.
% \begin{aatexample}
%   \fontspec[Diacritics=Show]{Palatino}
%    O´ \quad  O¨ \quad  O/ \par
%   \fontspec[Diacritics=Decompose]{Palatino}
%    O´ \quad  O¨ \quad  O/ \par
%   Better: \'O \"O \O % (requires xunicode)
% \end{aatexample}
% The \opt{Hide} option is for Arabic-like fonts which may be
% displayed either with or without vowel markings.
%
% No options for OpenType fonts.
%
%
% \subsection{Vertical position} 
% Some subscript (\opt{Superior}) and superscript (\opt{Inferior}) numbers and
% letters (and a small amount of punctuation, sometimes) are available
% in various fonts. The \opt{Ordinal} feature is (supposed to be)
% contextually sensitive to only raise characters that appear directly
% after a number.
% \begin{aatexample}
%   \fontspec{Skia Regular}
%    Normal
%   \fontspec[VerticalPosition=Superior]{Skia Regular}
%    Superior
%   \fontspec[VerticalPosition=Inferior]{Skia Regular}
%    Inferior                \\
%   \fontspec[VerticalPosition=Ordinal]{Skia Regular}
%    1st 2nd 3rd 4th 0th 8abcde
% \end{aatexample}
% OpenType fonts also have the option \opt{ScientificInferior} which
% extends further below the baseline than \opt{Inferior}s, as well as
% \opt{Numerator} and \opt{Denominator} for creating arbitrary fractions (see
% next section). Beware, the \opt{Ordinal} feature will not work
% correctly for all OpenType fonts!
% \begin{opentypeexample}
%   \fontspec[VerticalPosition=Superior]{Warnock Pro}
%    Sup: abdehilmnorst (-\$12,345.67)                      \\
%   \fontspec[VerticalPosition=Numerator]{Warnock Pro}
%    Numerator: 12345                                       \\
%   \fontspec[VerticalPosition=Denominator]{Warnock Pro}
%    Denominator: 12345                                     \\
%   \fontspec[VerticalPosition=ScientificInferior]{Warnock Pro}
%    Scientific~Inferior: 12345                             \\
%   \fontspec[VerticalPosition=Ordinal]{Warnock Pro}
%   `Ordinals': 1st 2nd 3rd 4th 0th
% \end{opentypeexample}
%
% \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.~\warn{v1.7}{This feature has
%   changed: no backwards compatibility!}
%
% In AAT fonts, the `fraction slash' or solidus character, which may
% be obtained by typing `{\fontspec{Lucida Grande}⌥⇧\,1}', is (supposed)
% to be used to create fractions. When \feat{Fractions} are turned
% \opt{On}, then (supposedly) only pre-drawn fractions will be used.
% \setmonofont[Scale=0.8]{Monaco}
% \begin{aatexample}
%   \fontspec[Fractions=On]{Palatino}
%    1⁄2 \quad 5⁄6 \\ % fraction slash
%    1/2 \quad 5/6    % regular  slash
% \end{aatexample}
% Using the \opt{Diagonal} option (AAT only), the font will attempt
% to create the fraction from superscript and subscript
% characters. This is shown in the following example by Hoefler Text,
% whose fraction support may actually not be turned off.
% \begin{aatexample}
%   \fontspec{Hoefler Text}
%          13579⁄24680 \\ % fraction slash
%    \quad 13579/24680    % regular  slash
% \end{aatexample}
% \setmonofont[Scale=0.95]{Osaka-Mono}
% OpenType fonts simply use a regular text slash to create fractions:
% \begin{opentypeexample}
%   \fontspec{Hiragino Maru Gothic Pro W4}
%    1/2 \quad 1/4 \quad 5/6 \quad 13579/24680 \\
%   \addfontfeature{Fractions=On}
%    1/2 \quad 1/4 \quad 5/6 \quad 13579/24680 \\
% \end{opentypeexample}
% Some (Asian fonts predominantly, perhaps) also provide for the
% \opt{Alternate} feature:
% \begin{opentypeexample}
%   \fontspec{Hiragino Maru Gothic Pro W4}
%    1/2 \quad 1/4 \quad 5/6 \quad 13579/24680 \\
%   \addfontfeature{Fractions=Alternate}
%    1/2 \quad 1/4 \quad 5/6 \quad 13579/24680 \\
% \end{opentypeexample}
% You may wish to use a command like the following to build arbitrary
% vulgar fractions in fonts with numerator and denominator glyphs if
% the font doesn't support it explicitly:
% \begin{opentypeexample}
%   \newcommand*\vulgarfraction[2]{%
%     {\addfontfeature{VerticalPosition=Numerator}#1}%
%      \textfractionsolidus
%     {\addfontfeature{VerticalPosition=Denominator}#2}}
%   \fontspec{Warnock Pro}
%   There's a reason they're called `vulgar':
%   \vulgarfraction{13579}{24680}
% \end{opentypeexample}
% (Requires the \pkg{xunicode} package for \cs{textfractionsolidus}.)
%
% \subsection{AAT Character Alternates} 
% Alternates are tricky, because there's no definition for what they
% can be. This is where the swashes are in Hoefler Text, but you can't
% guarantee that this is where they'll always be or that they'll use
% the same number. So unfortunately selection of Character Alternates
% must be done numerically on a per font basis (although
% \vref{sec:newfeatures} may help a little in this regard).
% \begin{aatexample}
%   \fontspec[Alternate=0]{Hoefler Text Italic}
%    Sphinx Of Black Quartz, {\scshape Judge My Vow} \\
%   \fontspec[Alternate=1]{Hoefler Text Italic}
%    Sphinx Of Black Quartz, {\scshape Judge My Vow}
% \end{aatexample}
% For an OpenType font, stylistic alternates used to be accessed
% through here, but now they're through the \feat{Style}
% feature~\warn{v1.7}{Yes, I don't have a high regard for backwards
%   compatibility at the moment. Sorry.}.
%
% \subsection{Variants}
% The \feat{Variant} feature takes a single numerical input for
% choosing different alphabetic shapes. Don't mind my fancy example
% \texttt{:)} I'm just looping through the nine~(\,!\,) variants of
% Zapfino.
% \begin{aatexample}
%   \Huge
%   \newcounter{var}\newcounter{trans}
%   \raisebox{0pt}[\height][0pt]{%
%     \whiledo{\value{var}<9}{%
%       \stepcounter{trans}%
%       \fontspec[Variant=\thevar,
%         Colour=005599\thetrans\thetrans]{Zapfino}%
%       \makebox[0.75\width]{d}%
%       \stepcounter{var}}}
% \end{aatexample}
% For OpenType fonts, \opt{Variant} selects a Stylistic Set, specified
% numerically between one and twenty. I don't have a font to
% demonstrate this feature with, unfortunately.
% 
% \subsection{Style}
% The options of the \feat{Style} feature 
% \warn{v1.7}{The old name, \feat{StyleOptions}, still works.} 
% are defined in AAT as one of the following: \opt{Display},
% \opt{Engraved}, \opt{IlluminatedCaps}, \opt{Italic}, 
% \opt{Ruby},\footnotemark\ \opt{TitlingCaps}, or \opt{TallCaps}.
% \footnotetext{`Ruby' refers to a small optical size, historically for

% \begin{aatexample}
%   \fontspec[Style=Engraved]{Hoefler Text}

% OpenType supported options are \opt{Alternate}~\warn{v1.7}{%
%   Note the difference with the \feat{Alternate} \emph{feature}, which is for
%   AAT fonts.}, 
% \opt{Italic}, \opt{Ruby},\footnotemark[\savemark] 
% \opt{Swash}, and \opt{TitlingCaps}.
% \setexsize\Large

%    TITLING CAPS
% \end{opentypeexample}
% (Look closely.)
%
% \subsection{Character Shape}
%
% There have been many standards for how Japanese (and other?) kanji
% glyphs are `supposed' to look. Some fonts will have many alternate
% glyphs available in order to be able to display these gylphs
% correctly in whichever form is appropriate. Both AAT and OpenType
% fonts support the following \feat{CharacterShape} options:
% \opt{Traditional}, \opt{Simplified}, \opt{JIS1978}, \opt{JIS1983},
% \opt{JIS1990}, and \opt{Expert}. OpenType also supports the \opt{NLC} option.
%
% \setexsize\LARGE
% \begin{opentypeexample}
%   \fontspec{Hiragino Mincho Pro W3}
%   {\addfontfeature{CharacterShape=Traditional}
%    唖噛躯 妍并訝 }                          \\
%   {\addfontfeature{CharacterShape=NLC}
%    唖噛躯 妍并訝 }                          \\
%   {\addfontfeature{CharacterShape=Expert}
%    唖噛躯 妍并訝 }
% \end{opentypeexample}
% 
% \subsection{Text Spacing}
%
% Many Asian fonts are equipped with variously spaced characters for
% shoe-horning into their generally monospaced text. These are
% accessed through the \feat{TextSpacing} feature.\footnote{Apple
%   seems to be adapting its AAT features in this regard (at least in
%   the fonts it distributes with \MacOSX) to have a one-to-one
%   correspondence with the equivalent OpenType features. Previously
%   AAT was more fine grained, but naturally they're not documenting
%   their AAT tables any more, so if the following features don't work
%   for a specific font let me know and I'll try and see if anything
%   can be salvaged from the situation.} For now, OpenType and AAT
% share the same six options for this feature: \opt{Proportional},
% \opt{FullWidth}, \opt{HalfWidth}, \opt{ThirdWidth},
% \opt{QuarterWidth}, \opt{AlternateProportional}, and
% \opt{AlternateHalfWidth}. AAT also allows \opt{Default} to return to
% whatever was originally specified.
%
% Japanese alphabetic glyphs (hiragana or katakana) may be typeset
% proportionally, to better fit horizontal measures, or monospaced, to
% fit into the rigid grid imposed by ideographic typesetting. In this
% latter case, there are also half-width forms for squeezing more kana
% glyphs (which are less complex than the kanji they are amongst) into
% a given block of space. The same features are given to roman letters
% in Japanese fonts, for typesetting foreign words in the same style
% as the surrounding text.
% \begin{opentypeexample}
%   \def\test{\makebox[2cm][l]{ようこそ}%
%             \makebox[2.5cm][l]{ワカヨタレソ}%
%             \makebox[2.5cm][l]{abcdef}}
%   \fontspec{Hiragino Mincho Pro W3}
%   {\addfontfeature{TextSpacing=Proportional}\test}\\
%   {\addfontfeature{TextSpacing=FullWidth}\test}\\
%   {\addfontfeature{TextSpacing=HalfWidth}\test}
% \end{opentypeexample}
% The same situation occurs with numbers, which are provided in
% increasingly illegible compressed forms: 
% \setexsize\large
% \begin{opentypeexample}
%   \fontspec{Hiragino Mincho Pro W3}
%   {\addfontfeature{TextSpacing=FullWidth}
%    ---12321---}\\
%   {\addfontfeature{TextSpacing=HalfWidth}
%    ---1234554321---}\\
%   {\addfontfeature{TextSpacing=ThirdWidth}
%    ---123456787654321---}\\
%   {\addfontfeature{TextSpacing=QuarterWidth}
%    ---12345678900987654321---}
% \end{opentypeexample}
%
%
%
% \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 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{aatexample}
%   \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{aatexample}
% For OpenType fonts, the only option supported is \opt{On} and \opt{Off}:
% \begin{opentypeexample}
%   \fontspec{Hiragino Maru Gothic Pro W4}
%    1 2 3 4 5 6 7 8 9                         \\
%   \addfontfeature{Annotation=On}
%    1 2 3 4 5 6 7 8 9    
% \end{opentypeexample}
% I'm not sure if \XeTeX\ can access alternate annotation
% forms, even if they exist (as in this case) in the font.
%
% \subsection{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 have any bold weight you like between
% the two extremes.
%
% \opt{Weight}, \opt{Width}, and \opt{OpticalSize} are supported by this
% package. Luckily Skia, which is distributed with
% Mac~OS~X, has these variable parameters, allowing for a
% demonstration:
% \begin{aatexample}
%   \fontspec[Weight=0.5,Width=3]{Skia Regular}
%    Really light and extended Skia         \\
%   \fontspec[Weight=2,Width=0.5]{Skia Regular}
%    Really fat and condensed Skia
% \end{aatexample}
% Variations along a Multiple Master font's optical size axis has been
% shown previously in \vref{sec:opticalsize}.
%
%
% \subsection{OpenType scripts and languages}
%
% When dealing with fonts that include glyphs for various languages,
% they may contain different font features for the different character
% sets and languages it supports. These may be selected with the
% \opt{Script} and \opt{Language} features. The possible options are
% tabulated in \vref{tab:ot-scpt} and \vref{tab:ot-lang},
% respectively.
%
% In the following examples, the same font is used to typeset the
% verbatim input and the \XeTeX\ output. Because the \opt{Script} is
% only specified for the output, the text is rendered incorrectly in
% the verbatim input. Many examples of incorrect diacritic spacing as
% well as a lack of contextual ligatures and rearrangement can be
% seen. Thanks to \name{Jonathan Kew}, \name{Yves Codet} and
% \name{Gildas Hamel} for their contributions towards these examples.

% \section{Defining new features}
% \label{sec:newfeatures}
% This package cannot hope to contain every possible font
% feature. Two 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{\newfontfeature}
% \cmd{\newfontfeature}\marg{tag}\marg{feature string} takes two
% arguments: \meta{tag} is the name to reference the new feature by
% when selecting it in your font; and \meta{feature string} the string
% that activates the particular font feature. For example, Zapfino
% contains a non-standard feature `Avoid d-collisions'. To access it
% with this package, you could do the following:
% \begin{aatexample}
%   \newfontfeature{AvoidD}{Special=Avoid d-collisions}
%   \newfontfeature{NoAvoidD}{Special=!Avoid d-collisions}
%   \fontspec[AvoidD,Variant=1]{Zapfino} 
%    sockdolager rubdown               \\
%   \fontspec[NoAvoidD,Variant=1]{Zapfino} 
%    sockdolager rubdown
% \end{aatexample}
% Of course, you may perform similar operations with OpenType
% features, \eg, |\newfontfeature{OTSwash}{+swsh}| to activate swash forms.
%
% \DescribeMacro{\newfeaturecode}
% \cmd{\newfeaturecode}\marg{tag}\marg{feature number}\marg{selector
%   number} performs the same function as the last macro, but instead
% of using a string, it takes two arguments to define the
% \meta{feature number} and \meta{selector number} of the feature. It
% works only for AAT fonts. There is no mechanism yet for the package
% to help inform you what codes are available for a specific font, sorry.
% \begin{aatexample}
%   \newfeaturecode{Swash}{17}{1}
%   \fontspec[Swash]{Hoefler Text Italic}
%    This is XeTeX by Jonathan Kew.
% \end{aatexample}
%
% \iffalse
% \subsection{Renaming existing features}\label{sec:aliasfeature}
%
% \DescribeMacro{\aliasfeature} 
% If you don't like the name that a certain font feature is defined with,
% it may be aliased to another with the
% \cs{aliasfeature}\marg{existing name}\marg{new name} command:
% \begin{aatexample}
%   \aliasfeature{VerticalPosition}{Vert Pos}
%   \fontspec[Vert Pos=Ordinal]{Hoefler Text}
%   0th 1st 2nd 3rd 4th 5th
% \end{aatexample}
% (Yes, note yet another Hoefler Text bug.)
%
% Spaces in feature and option names \emph{are} allowed (you may have
% noticed this in the lists of OpenType scripts and languages). This
% command only works (for now) with \emph{font} features. What does
% this mean? You can't alias \feat{BoldFont}, or \feat{Mapping}, or
% \feat{Script}, or\dots

% \section{Implementation}
% Herein lies the implementation details of this package. Welcome!
% It's my first.
% 
% For some reason, I decided to prefix all the package internal
% command names and variables with |zf|. I don't know why I chose
% those letters, but I guess I just liked the look/feel of the
% letters together at the time.  
%    \begin{macrocode}
%<*fontspec> 
%    \end{macrocode} 
% Only proceed if it is \XeTeX\ that is doing the typesetting.
%    \begin{macrocode}
\expandafter\ifx\csname XeTeXversion\endcsname\relax
  \@latex@error{^^J
   *************************************************^^J
   *** Sorry!                                       ^^J
   *** The fontspec package only works with XeTeX.  ^^J
   *************************************************}
\fi
%    \end{macrocode}
% While the business of encoding names is up in the air, I'll continue
% to use the |U| encoding.
% \changes{v1.6}{2005/03/03}{\textsf{utf8accents} is no longer loaded
%   by this package!}

\def\zf@enc{U}
%\RequirePackage[\zf@enc]{fontenc}
\renewcommand\encodingdefault{\zf@enc}
%    \end{macrocode}
% \DescribeMacro{\define@key}\DescribeMacro{\setkeys} The \pkg{keyval}
% package makes processing comma separated inputs very simple with the
% \cs{define@key} and \cs{setkeys} commands:
% \begin{itemize}
% \item \cmd{\define@key}\marg{family}\marg{option}\marg{commands
%       to process}
% \item \cmd{\setkeys}\marg{family}\marg{input list}
% \end{itemize}
% \cmd{\define@key} is used to define each \meta{option}, grouped by
% \meta{family}, each of which executes its \meta{commands to process}
% when it is included in an \meta{input list} in a call to
% \cmd{\setkeys}.
%    \begin{macrocode}
\RequirePackage{keyval}
%    \end{macrocode}
%
% A typical example of what happens when this package runs various
% user commands is outlined below. I'll find some better way of
% slotting it into the real documentation sometime in the future.
%
% \begin{enumerate}
% \item The commands
%       \begin{Verbatim}[gobble=8]
%         \defaultfontfeatures{Numbers=OldStyle}
%         \fontspec[Ligatures=Rare]{Warnock Pro}
%       \end{Verbatim}
% \item are equivalent to
%       \begin{Verbatim}[gobble=8]
%         \fontspec[Numbers=OldStyle,%
%                   Ligatures=Rare]{Warnock Pro}
%       \end{Verbatim}
% \item which produces the font family
%       \begin{Verbatim}[gobble=8]
%         WarnockPro+onum+dlig
%       \end{Verbatim}
%       (for use with \cs{fontfamily{}}, \etc)
% \item which, in \cs{csname...}\cs{endcsname}, gives
%       \begin{Verbatim}[gobble=8]
%         {Numbers=OldStyle,Ligatures=Rare}%
%         {Warnock Pro}
%       \end{Verbatim}
% \item This is used by
%       \begin{Verbatim}[gobble=8]
%         \addfontfeature{Color=CC0000}
%       \end{Verbatim}
% \item which is in this case equivalent to
%       \begin{Verbatim}[gobble=8]
%         \fontspec[Numbers=OldStyle,%
%                   Ligatures=Rare,%
%                   Color=CC0000]{Warnock Pro}
%       \end{Verbatim}
% \item and the process starts again.
% \end{enumerate}
%
% \subsection{User commands}\label{sec:codeuser}
%
%
% This section contains the definitions of the commands detailed in
% the user documentation.  Only the `top level' definitions of the
% commands are contained herein; they all use or define macros which
% are defined or used later on in \vref{sec:codeinternal}.
%
%
% \subsubsection{Font selection}
% \begin{macro}{\fontspec}
%   This is the main command of the package that
%   selects fonts with various features. It takes two arguments: the
%   Mac OS X font name and the optional requested features of that
%   font. It simply runs \cs{zf@fontspec}, which takes the same
%   arguments as the top level macro and puts the new-fangled font
%   family name into the global \cmd{\zf@family}. Then this new font
%   family is selected.
%
%   \changes{v1.6}{2005/01/25}{Removed \cs{zf@currfont} (unnecessary)}
%
%    \begin{macrocode}
\newcommand*\fontspec[2][]{%
  \zf@fontspec{#1}{#2}%
  \fontfamily\zf@family\selectfont}
%    \end{macrocode}
% \end{macro}
%
%
%
% \begin{macro}{\setromanfont}
%
%   \changes{v1.1}{2004/10/18}{Implemented (with friends).}
%   \changes{v1.6}{2005/01/25}{Changed \cs{rmdefault}, etc., assigning
%     to use \cs{let} directly.}
%
% \begin{macro}{\setsansfont} \begin{macro}{\setmonofont} 
%
%     The following three macros perform equivalent operations setting
%     the default font (using \cs{let} rather than \cs{renewcommand}
%     because \cs{zf@family} will change in the future) for a
%     particular family: roman, sans serif, or typewriter
%     (monospaced). I end them with |\normalfont| so that if they're
%     used in the document, the change registers immediately.

%
% \begin{macro}{\setmathsf} \begin{macro}{\setboldmathrm} \begin{macro}{\setmathtt} 
%
% These commands are analogous to \cmd\setromanfont\ and others,
% but for selecting the font used for \cmd\mathrm, \etc. They
% can only be used in the preamble of the
% document. \cmd\setboldmathrm\ is used for specifying which
% fonts should be used in \cmd\boldmath.
%
%    \begin{macrocode}
\newcommand*\setmathrm[2][]{%
  \zf@fontspec{#1}{#2}%
  \let\zf@rmmaths\zf@family}

%    \end{macrocode}
% If the commands above are not executed, then \cmd\rmdefault\ (etc.)
% will be used.

\def\zf@sfmaths{\sfdefault}
\def\zf@ttmaths{\ttdefault}
%    \end{macrocode}
% \end{macro} \end{macro} \end{macro} \end{macro}
%
%
%
% \begin{macro}{\newfontinstance}
%   \changes{v1.6}{2005/01/02}{Implemented.}  
%
%   This macro takes the arguments of \cs{fontspec} with a prepended
%   \meta{instance cmd} (code for middle optional argument generated
%   by \name{Scott Pakin}'s \textsf{newcommand.py}). This command is used
%   when a specific font instance needs to be referred to repetitively
%   (\eg, in a section heading) since continuously calling
%   \cs{zf@fontspec} is inefficient because it must parse the
%   option arguments every time.
%
%   \cs{zf@fontspec} defines a font family and saves its name in
%   \cs{zf@family}. So then this value is expanded in a temporary
%   macro also containing the \emph{unexpanded} commands to later
%   select the font family to which it refers. Finally, the requested
%   name for the font instance is \cs{let}ed from the temporary macro.
%
%    \begin{macrocode}
\newcommand*\newfontinstance[1]{%
  \@ifnextchar[{\newfontinstance@i#1}{\newfontinstance@i#1[]}}
\def\newfontinstance@i#1[#2]#3{%
  \zf@fontspec{#2}{#3}%
  \edef\zf@tempinst{\noexpand\fontfamily{\zf@family}\noexpand\selectfont}%
  \let#1\zf@tempinst}
%    \end{macrocode}
% \end{macro}
%
%
% \subsubsection{Font feature selection}
%
% \begin{macro}{\defaultfontfeatures}
%
% \changes{v1.3}{2004/10/25}{Implemented.}
% \changes{v1.4}{2004/11/25}{Name changed from \cs{setdefaultoptions}.}
%
% \begin{macro}{\zf@default@options}
%
%   This macro takes one argument that consists of all of feature
%   options that will be applied by default to all subsequent
%   \cs{fontspec}, et al., commands. It stores its value in
%   \cs{zf@default@options} (initialised empty), which is
%   concatenated with the individual macro choices in the
%   \cs{zf@get@feature@requests} macro.
%
%    \begin{macrocode}
\newcommand*\defaultfontfeatures[1]{\def\zf@default@options{#1}}
\let\zf@default@options\@empty
%    \end{macrocode}
% \end{macro} \end{macro}
%
%
%
% \begin{macro}{\addfontfeatures}
%
%   In order to be able to extend the feature selection of
%   a given font, two things need to be known: the currently selected
%   features, and the currently selected font. Every time a font
%   family is creating, this information is saved inside a control
%   sequence with the name of the font family itself.
%
%   This macro extracts this information, then appends the requested
%   font features to add to the already existing ones, and calls the
%   font again with the top level \cs{fontspec} command.
%
%   The default options are \emph{not} applied (which is why they're
%   saved and restored with \cs{zf@default@options@old}), so this
%   means that the only added features to the font are strictly those
%   specified by this command.
%
%   \cs{addfontfeature} is defined as an alias, as I found that I
%   often typed this instead when adding only a single font feature.
%
%   \changes{v1.5}{2004/11/29}{Implemented.}
%   \changes{v1.6}{2005/02/03}{Removed \cs{relax}ing of temporary macros.}

%   \cs{newfontfeature} takes two arguments: the name of the feature

%   defined, a control sequence is defined made up of the
%   concatenation of |+zf-| and the new feature tag. This long-winded
%   control sequence is then called upon to update the font family
%   string when a new instance is requested.

% \subsection{Internal macros}\label{sec:codeinternal}
%
%
% \begin{macro}{\zf@fontspec}
%   This is the command that defines font families for use. Given a
%   list of font features (|#1|, stored in \cs{zf@options} for
%   \cs{zf@get@feature@requests}) for a requested font (|#2|, stored
%   in \cs{zf@macname} globally for the \cs{zf@set@font@type} and
%   \cs{zf@make@aat@feature@string} macros), it will define an NFSS
%   family for that font and put the family name into \cs{zf@family}.
%
%   Then we check with \cs{zf@set@font@type} whether the font is AAT
%   or OpenType, and convert the requested features to font definition
%   strings. This is performed with \cs{zf@get@feature@requests}, in
%   which \cs{setkeys} retrieves the requested font features and
%   processes them. To build up the complex family name, it
%   concatenates each font feature with the family name of the
%   font. So since \cs{setkeys} is run more than once (since different
%   font faces may have different feature names), we only want the
%   complex family name to be built up once, hence the \cs{zf@firsttime}
%   conditionals.
%
% \changes{v1.7}{2005/03/22}{Optional argument now mandatory.}

% Now that we have the complex family name, we

% do so. Once the family name is created, save \emph{in} it the user
% string of the requested options and font name for use with
% \cs{addfontfeatures} (this info is separately braced for easy
% extraction with the \cs{@first-} and \cs{@secondoftwo} commands).
%
% \cs{zf@current@options} is the option list prepended by the default
% option list, if any.

%   This macro uses \cs{DeclareFontShape} to define the font shape in

%   necessitates |\globaldefs=1| so the macro is visible to the rest
%   of the package. The mandatory arguments are: |#2|~the font name,
%   |#3|~the font series, and |#4|~the font shape. The optional
%   argument is used when making the font shapes for bold, italic, and
%   bold italic fonts using \XeTeX's auto-recognition with |/B|, |/I|,
%   and |/BI| font name suffixes. If no such font is found, it falls
%   back to the original font name, in which case this macro doesn't

% \subsection{Italic small caps} \label{sec:sishape} 
% The following code for utilising italic small caps sensibly is taken
% pretty much verbatim from Philip Lehman's \textit{Font Installation
%   Guide}. Note that |\upshape| needs to be used \emph{twice} to get
% from italic small caps to regular upright (it always goes to small
% caps, then regular upright).
% \begin{macro}{\sishape}\begin{macro}{\textsi}
%     First, the commands for actually selecting italic small caps are
%     defined. I use |si| as the NFSS shape for italic small caps, but
%     I have seen |itsc| and |slsc| also used. |\sidefault| may be
%     redefined to one of these if required for compatibility.
%    \begin{macrocode}
\providecommand*{\sidefault}{si}
\DeclareRobustCommand{\sishape}{%
  \not@math@alphabet\sishape\relax
  \fontshape\sidefault\selectfont}
\DeclareTextFontCommand{\textsi}{\sishape}
%    \end{macrocode}
% \end{macro} \end{macro}
% \begin{macro}{\zf@merge@shape}
%   This is the macro which enables the overload on the |\..shape|
%   commands. It takes three such arguments. In essence, the macro
%   selects the first argument, unless the second argument is already
%   selected, in which case it selects the third.
%    \begin{macrocode}
\newcommand*{\zf@merge@shape}[3]{%
  \edef\@tempa{#1}%
  \edef\@tempb{#2}%
  \ifx\f@shape\@tempb
    \expandafter\ifx
    \csname\f@encoding/\f@family/\f@series/#3\endcsname
    \relax\else
      \edef\@tempa{#3}% 
    \fi 
  \fi 
  \fontshape{\@tempa}\selectfont}
%    \end{macrocode}
% \end{macro}
% \begin{macro}{\itshape} \begin{macro}{\scshape} \begin{macro}{\upshape}
%       Here the original |\..shape| commands are redefined to use the
%       merge shape macro.
%    \begin{macrocode}
\DeclareRobustCommand{\itshape}{% 
  \not@math@alphabet\itshape\mathit

% \subsection{Selecting maths fonts}
% Here, the fonts used in math mode are redefined to correspond to the
% default roman, sans serif and typewriter fonts. Unfortunately, you
% can only define maths fonts in the preamble, otherwise I'd run this
% code whenever \cs{setromanfont} and friends was run.

%
% Since every maths setup is slightly different, we also take
% different paths for defining various math glyphs depending which
