+README for the `xfrac' package.
+
+The `xfrac' package is designed for production of split level
+fractions in LaTeX2e*. Yes that's right: there is indeed a star in
+the LaTeX version. It is very much a prototype implementation
+intended for future use, so you'll need an up-to-date (at least at
+the time of writing) LaTeX setup.
+
+Dependencies are:
+ e-TeX extensions needed in the LaTeX format
+ LaTeX release of 2003/12/01
+ The LaTeX2e* package `template'
+ The experimental package `xparse'
+
+The last two of these dependencies can be downloaded as part of
+the `xbase' bundle from
+ http://www.latex-project.org/code/experimental/
+
+Documentation dependencies are
+ The `nicefrac' package (part of the `units' bundle)
+ The `eco' package and its virtual fonts.
+
+These two are just to illustrate problems often seen when not
+using an advanced approach such as `xfrac'.

+%
+% \section{A Bit of History}
+%
+% \subsection{The Past}
+%
+% One of the first exercises in \emph{The \TeX Book} is to design a
+% macro for split level fractions. The solution shows a level of
+% simplicity only rivaled by its fundamental design flaws: It can
+% only be used when the text font and the math font are the same and
+% worse still it uses a \emph{virgule} (a slash) for separating the
+% two components. The proper symbol for that is a \emph{solidus}
+% which sadly is absent from Computer Modern. It is however
+% available in the European Computer Modern fonts, but I'll get back
+% to that.
+%
+% \subsection{The Present}
+%
+% So how does people produce split level fractions nowadays? The
+% answer is that they use the \package{nicefrac} package. For text
+% it gives you \nicefrac{1}{2}, while the built-in
+% \package{textcomp} symbol is \textonehalf. Hmmm, bad example due
+% to the strange design of the EC fonts. Lets try Palatino instead.
+% Then |\nicefrac{1}{2}| produces \switch{ppl}{\nicefrac{1}{2}}
+% while the built-in symbol is \switch{ppl}{\textonehalf}, and it's
+% plain to see the problems; a)~it uses the virgule instead of the
+% solidus and b)~the font size of the numerator and the denominator
+% is bigger than in the built-in symbol. We'll have to take care of
+% this somehow.
+%
+% Another problem arises when the font has old style figures as the
+% \package{eco} package provides for Computer Modern. Here we get
+% results like \switch{cmor}{\nicefrac{1}{2}} and
+% \switch{cmor}{\nicefrac{8}{9}}. We'll have to do better than that.
+%
+% That was text mode. I wonder what happens in math mode?
+% \begin{verbatim}
+% \[
+% \mathbf{ 2 \times \nicefrac{1}{2} }
+% \times \mathit{2\times \nicefrac{1}{2}}
+% \]
+% \end{verbatim}
+% \[
+% \mathbf{ 2 \times \nicefrac{1}{2} }
+% \times \mathit{2\times \nicefrac{1}{2}}
+% \]
+% Whoops! Didn't see that coming, did you? I certainly didn't.
+%
+%
+% This section sounds very much like me tearing the
+% \package{nicefrac} package apart and well, yes, that's precisely
+% what I'm doing. It \emph{is} simple and it \emph{does} produce
+% somewhat acceptable results for Computer Modern, but if we want a
+% single package for producing such fractions we need a radical new
+% approach.
+%
+%
+%
+%
+% \subsection{The Future}
+%
+% Fonts are wildly different; one macro that works fine for Computer
+% Modern obviously doesn't work well at all in Palatino. For one we
+% have to make the separator symbol configurable, and we need to
+% take care of several details as well: font scaling of the
+% numerator/denominator pair (ND), font selection of ND etc. If we
+% are to have a single package for this in the future\footnote{As
+% this is intended to be about the future, the \package{xfrac} package
+% requires the \eTeX{} extensions.} we have to define a totally
+% generic interface for the fraction commands and then adjust
+% parameters depending on the current font. What you see in this
+% prototype implementation of \package{xfrac} is just that.
+%
+%
+% \section{The User Interface}
+%
+% The \package{xfrac} package defines a document command \cs{sfrac}
+% with the following syntax:
+% \begin{quote}
+% \cs{sfrac}\oarg{instance}\marg{num}\oarg{sep}\marg{denom}
+% \end{quote}
+% Lets show a few examples:
+% \begin{verbatim}
+% \sfrac{1}{2}, $\sfrac{1}{2}$,
+% $\mathbf{3\times\sfrac{1}{2}}$
+% \quad \fontfamily{ppl}\selectfont Palatino: \sfrac{1}{2}
+% \quad \fontfamily{ptm}\selectfont Times: \sfrac{1}{2}
+% \end{verbatim}
+% \begin{quote}
+% \sfrac{1}{2}, $\sfrac{1}{2}$, $\mathbf{3\times\sfrac{1}{2}}$
+% \quad \fontfamily{ppl}\selectfont Palatino: \sfrac{1}{2}
+% \quad \fontfamily{ptm}\selectfont Times: \sfrac{1}{2}
+% \end{quote}
+% You'll notice something interesting: Not only does the \cs{sfrac}
+% command work as it should in math mode, it also gets the job done
+% for other fonts as well.
+%
+% \subsection{Text mode}
+%
+% The usual problem in text mode has a name: Computer Modern. The
+% solidi of all the Computer Modern fonts leave a lot to be desired,
+% although things are potentially looking better as the Latin Modern
+% fonts are becoming more stable and widespread. As long as the
+% default fonts are Computer Modern variants we must however work
+% around this. One idea that comes to mind is to see what happens
+% when you use a solidus from another font instead. Lets try with
+% Times:
+% \begin{quote}
+% \DeclareInstance{xfrac}{cmr2}{text}{
+% slash-symbol-font = ptm,
+% }
+% ``You take \sfrac[cmr2]{1}{2} cup of sugar, \ldots''
+% \end{quote}
+% That looks quite good actually, so it was probably very difficult
+% to obtain that result. Nope, it was extremely easy---if you happen
+% to know about \emph{instances}:
+% \begin{verbatim}
+% \DeclareInstance{xfrac}{cmr}{text}{
+% slash-symbol-font = ptm,
+% }
+% \end{verbatim}
+% So we define an instance with the name `cmr' from the template
+% `text' which in turn is of template type `xfrac'. You'll notice
+% the `cmr' is also the name of the font family for Computer Modern
+% Roman and the reasoning behind is that every font family should
+% have it's own settings, and if a document command is to work well
+% in that scheme, letting it use the name of the current font family
+% seems like a good idea. Thus the \cs{sfrac} command checks to see
+% whether an instance with same name as the current font family
+% exists and uses it if the test is true; otherwise the default
+% setting is used. Here we defined the instance to be used for the
+% font family `cmr' and just told it to use the Times font for
+% typesetting the slash symbol which turns out to be a solidus by
+% default.
+%
+% The option \texttt{cm-recommended} which is loaded by default uses
+% the Times solidus for Computer Modern Roman and Computer Modern
+% Sans Serif and the Palatino solidus for Computer Modern Typewriter
+% Type. This looks quite good. Should you however not want this you
+% can use the option \texttt{cm-standard} which produces somewhat
+% acceptable results using Computer Modern exclusively.
+%
+% So what about old style figures? If you use the \package{eco}
+% package you might define an instance similar to this (`cmor' is
+% the name of the roman font activated by \package{eco}):
+% \DeclareInstance{xfrac}{cmor}{text}{
+% slash-symbol-font = ptm,
+% numerator-font = cmr,
+% denominator-font = cmr,
+% }
+% \begin{verbatim}
+% \DeclareInstance{xfrac}{cmor}{text}{
+% slash-symbol-font = ptm,
+% numerator-font = cmr,
+% denominator-font = cmr,
+% }
+% \end{verbatim}
+% We also use regular Computer Modern Roman for typesetting ND, so
+% we end up with \switch{cmor}{\sfrac{1}{2}} and
+% \switch{cmor}{\sfrac{8}{9}} instead of
+% \switch{cmor}{\nicefrac{1}{2}} and \switch{cmor}{\nicefrac{8}{9}}.
+% Much better.
+%
+% There are also situations where other tricks are useful. If you
+% don't have the inferior and superior figures available in a font,
+% or the font doesn't have a wider design for small font sizes, you
+% can cheat by manually scaling the ND-pair. I got nice results for
+% Adobe's Stempel Garamond (with small caps and old style figures)
+% with the following setup:
+% \begin{verbatim}
+% \DeclareInstance{xfrac}{pegj}{text}{
+% numerator-font = pegx,
+% denominator-font = pegx,
+% scale-factor = .9,
+% h-scale = 1.1,
+% }
+% \end{verbatim}
+% We use the font family `pegx' (Stempel Garamond with real small
+% caps) for typesetting the ND-pair. Additionally the key
+% \key{scale-factor} specifies that the font size used for the
+% ND-pair should be $0.9$ of the height of the solidus, and the key
+% \key{h-scale} specifies that the ND-pair should be scaled an extra
+% 10\% horizontally.
+%
+% Should you be so fortunate the have a font with inferior and
+% superior figures like in the Monotype Janson example from Philipp
+% Lehman's excellent \emph{The Font Installation Guide}. In that
+% example Philipp defines the font families `mjn0' for the inferior
+% figures and `mjn1' for the superior. Thus to get the \cs{sfrac}
+% command to use them on the fly for the font family `mjnj' (Janson,
+% old style figures) we would say
+% \begin{verbatim}
+% \DeclareInstance{xfrac}{mjnj}{text}{
+% numerator-font = mjn1,
+% denominator-font = mjn0,
+% scaling = false,
+% numerator-bot-sep = 0pt,
+% denominator-bot-sep = 0pt,
+% }
+% \end{verbatim}
+% I think this example is a very clean way to do it. An alternative
+% approach could be to use the keys \key{numerator-format} and
+% \key{denominator-format} to process the arguments and let them
+% determine what to do.
+%
+% As a side note Harald Harders was so kind to test it, and it
+% \emph{does} actually work---I hadn't tested it myself.
+%
+% \subsection{Math Mode}
+%
+% In math mode the choices are a lot fewer because first of all
+% \TeX{} comes with a built-in limitation of 16 math families.
+% Additionally we will not need a solidus for typesetting split
+% fractions in math, as tradition is to use a virgule instead. We
+% define the basic `mathdefault' instance to simply use the math
+% family in use when the instance is run. So if we're in normal math
+% like |$\sfrac{7}{9}$| we simply get family~$-1$. If we're inside a
+% \cs{mathbf} we're in family~$4$ (in the standard setup at least),
+% and so the fraction is typeset with the same math family. Simple,
+% isn't?
+%
+% You can also declare instances for the math families, but I really
+% don't see why you would. If you do then name them according to the
+% scheme `mathfam\meta{N}', where \meta{N} is the family number, and
+% only do it if you \emph{really} know how to set up math fonts.
+% That is, if \cs{DeclareMathAlphabet} is unbeknownst to you, then
+% just don't go there.
+%
+%
+% Another example: If we want \cs{sfrac} to produce split fractions
+% without doing anything at all, we can choose the collection
+% `plainmath', which is defined as
+% \begin{verbatim}
+% \DeclareCollectionInstance{plainmath}{xfrac}{mathdefault}{math}{
+% denominator-bot-sep = 0pt,
+% numerator-bot-sep = 0pt,
+% numerator-top-sep = \maxdimen,
+% scaling = false,
+% slash-right-mkern = 0mu,
+% slash-left-mkern = 0mu,
+% }
+% \end{verbatim}
+% This creates an alternative version of the instance `mathdefault'
+% with settings as specified by the keys. In the default math setup
+% \key{numerator-top-sep} is set to 0~pt, and here we set
+% \key{numerator-bot-sep} to 0~pt as well, so in order to avoid
+% over-specification (and an error message) we must set
+% \key{numerator-top-sep} to \cs{maxdimen}. We activate (obeying
+% normal scoping rules) it with:
+% \begin{verbatim}
+% \UseCollection{xfrac}{plainmath}
+% \end{verbatim}
+% Then |$\sfrac{8}{13}$| produces\begingroup
+% \UseCollection{xfrac}{plainmath}
+% $\sfrac{8}{13}$ and just typing |$8/13$| gives the same result:
+% $8/13$.

+% \TemplateSemantics
+%
+% This template is a restricted version of the `text' template. Only
+% the keys that are different from the `text' template are shown
+% here. Also bear in mind that the attributes \key{slash-left-kern}
+% and \key{slash-right-kern} have no meaning in this template.
+%
+% \end{TemplateDescription}
+%
+%
+%
+% \StopEventually{}
+%
+% \section{Implementation}
+%
+% We set up the programming interface. We need the
+% \package{template} and \package{xparse} packages from the
+% experimental code, more precisely from the `xbase' bundle. The
+% other packages are well-known.
+% \begin{macrocode}
+\RequirePackage{textcomp,graphicx,amstext}
+\RequirePackage{template}[2001/07/25]
+\RequirePackage{xparse}[2000/01/29]
+% \end{macrocode}
+% \changes{v0.10b}{2004/04/07}{Now uses \cs{InternalSyntaxOn}} With
+% v0.10b I introduced the new internal syntax using |_| and |:|.
+% White space is ignored as well, so any |@|-signs in the code are
+% remnants of old \LaTeX{} coding conventions.
+% \begin{macrocode}
+\InternalSyntaxOn
+% \end{macrocode}
+% Some programming tools which will probably be included in the
+% \LaTeX3 API.
+% \begin{macrocode}
+\@ifundefined{else:}{\let\else:=\else}{}
+\@ifundefined{fi:}{\let\fi:=\fi}{}
+\@ifundefined{if_dim:w}{\let\if_dim:w =\ifdim}{}
+\@ifundefined{if_mathmode:}{\let\if_mathmode: =\ifmmode}{}
+\def\xfrac_namelet:cN #1#2{%
+ \expandafter\let\csname#1\endcsname#2}
+% \end{macrocode}
+% Boolean data type. No error checking!
+% \begin{macrocode}
+\def\xfrac_new_boolean:c #1{
+ \expandafter\@ifdefinable\csname if_boolean_#1:\endcsname{
+ \@namedef{boolean_#1_true:}
+ {\xfrac_namelet:cN{if_boolean_#1:}\iftrue}%
+ \@namedef{boolean_#1_false:}
+ {\xfrac_namelet:cN{if_boolean_#1:}\iffalse}%
+ \@nameuse{boolean_#1_false:}%
+ }
+}
+\def\xfrac_set_boolean:cc #1#2{ \@nameuse{boolean_#1_#2:}}
+\def\if_boolean:cTF #1{
+ \@nameuse{if_boolean_#1:}
+ \expandafter\@firstoftwo

+\def\if_boolean:cT #1#2{ \if_boolean:cTF {#1}{#2}{} }
+\def\if_boolean:cF #1#2{ \if_boolean:cTF {#1}{}{#2} }
+% \end{macrocode}
+%
+% An option:
+% \begin{macrocode}
+\xfrac_new_boolean:c {cm_recommended}
+\DeclareOption{cm-recommended}
+ { \xfrac_set_boolean:cc {cm_recommended}{true} }
+\DeclareOption{cm-standard}
+ { \xfrac_set_boolean:cc {cm_recommended}{false} }
+\ExecuteOptions{cm-recommended}
+\ProcessOptions\relax
+% \end{macrocode}
+%
+% \begin{macro}{\l_xfrac_temp_box}
+% \begin{macro}{\l_xfrac_slash_box}
+% We use two box registers. We could probably get away with using
+% scratch boxes, but this feels safer. Anyway we're all using
+% \eTeX{} now so why not?
+% \begin{macrocode}
+\newsavebox\l_xfrac_temp_box
+\newsavebox\l_xfrac_slash_box
+% \end{macrocode}
+% \end{macro}
+% \end{macro}
+%
+% \subsection{The Templates}
+% Then we declare the template.
+% \begin{macrocode}
+\DeclareTemplateType{xfrac}{3}
+% \end{macrocode}
+% The template type `text'.
+% \begin{macrocode}
+\DeclareTemplate{xfrac}{text}{3}{

+ {\def\xfrac_fontscale: {
+ \fontsize{\xfrac_scalefactor: \xfrac_relscale:}{\z@}\selectfont}}
+ { \let\xfrac_fontscale: \relax },
+% \end{macrocode}
+% Here comes some fake lengths. I've decided to call them with the
+% suffix |_fdim|, so that I will remember to use them right.
+% \begin{macrocode}
+ numerator-top-sep = L [\maxdimen] \l_xfrac_numeratortopsep_fdim,

+% \end{macrocode}
+% As calc can't handle |\muskip|s, I've made them of type `n' and
+% added the suffix |_fmu| to indicate `fake mu skip'.
+% \begin{macrocode}

+ }
+ }
+}
+% \end{macrocode}
+%
+% Since math and text mode are wildly different entities we define a
+% separate template for each. You already saw the `text' template,
+% and here is the `math' template.
+% \begin{macrocode}
+\DeclareRestrictedTemplate{xfrac}{math}{text}{
+ numerator-font = \number\fam,
+ slash-symbol = /,
+ slash-symbol-font = \number\fam,
+ denominator-font = \number\fam,
+ scale-factor = 0.7,
+ scale-relative = false,
+ scaling = true,
+ numerator-top-sep = 0pt,
+ denominator-bot-sep = 0pt,
+ math-mode = true,
+ phantom = (,
+}
+% \end{macrocode}
+%
+% \subsection{The Default Instances}
+%
+% For the default instances we just use the relevant templates with
+% the default settings.
+%
+% The default `text' instance.
+% \begin{macrocode}
+\DeclareInstance{xfrac}{default}{text}{ }
+% \end{macrocode}
+% The default `math' instance.
+% \begin{macrocode}
+\DeclareInstance{xfrac}{mathdefault}{math}{ }
+% \end{macrocode}
+% \begin{macrocode}
+\DeclareCollectionInstance{plainmath}{xfrac}{mathdefault}{math}{
+ denominator-bot-sep=0pt,
+ numerator-bot-sep=0pt,
+ numerator-top-sep=\maxdimen,
+ scale-factor = 1,
+ scale-relative = false,
+ scaling = true,
+ slash-right-mkern=0mu,
+ slash-left-mkern=0mu,
+}
+% \end{macrocode}
+% Default Computer Modern setup. Far from optimal, but better than
+% nothing.
+% \begin{macrocode}
+\DeclareInstance{xfrac}{cmr}{text}{
+ denominator-bot-sep=0pt,
+ numerator-top-sep=\DelayEvaluation{.2ex},
+ slash-left-kern=\DelayEvaluation{-.1em},
+ slash-right-kern=\DelayEvaluation{-.1em},
+}
+\DeclareInstance{xfrac}{cmss}{text}{
+ denominator-bot-sep=0pt,
+ numerator-top-sep=\DelayEvaluation{.2ex},
+ slash-left-kern=\DelayEvaluation{-.1em},
+ slash-right-kern=\DelayEvaluation{-.1em},
+}
+\DeclareInstance{xfrac}{cmtt}{text}{
+ denominator-bot-sep=0pt,
+ numerator-top-sep=\DelayEvaluation{.2ex},
+ slash-left-kern=\DelayEvaluation{-.1em},
+ slash-right-kern=\DelayEvaluation{-.1em},
+}
+% \end{macrocode}
+% We can do better for the Computer Modern fonts. For the roman
+% family we choose Times.
+% \begin{macrocode}
+\DeclareCollectionInstance{cm-recommended}{xfrac}{cmr}{text}{
+ slash-symbol-font = ptm,
+}
+% \end{macrocode}
+% Times also blends well with `cmss'.
+% \begin{macrocode}
+\DeclareCollectionInstance{cm-recommended}{xfrac}{cmss}{text}{
+ slash-symbol-font = ptm,
+}
+% \end{macrocode}
+% For `cmtt' we choose the Palatino solidus as it is slightly
+% thicker than Times.
+% \begin{macrocode}
+\DeclareCollectionInstance{cm-recommended}{xfrac}{cmtt}{text}{
+ slash-symbol-font = ppl,
+}
+% \end{macrocode}
+% If we used the \texttt{cm-recommended} setup we activate it.
+% \begin{macrocode}
+\if_boolean:cT {cm_recommended}
+ {\UseCollection{xfrac}{cm-recommended}}
+% \end{macrocode}
+%
+% \subsection{The User Command}
+%
+% Currently there is just a single user command. \cs{sfrac} takes
+% two mandatory arguments: numerator and denominator. It can take an
+% optional argument between the mandatory specifying the separator
+% like this:
+% \begin{verbatim}
+% \sfrac{7}[/]{12}
+% \end{verbatim}
+% It also has an optional argument that comes before the first
+% mandatory argument. If used it will use that instance instead of
+% the auto-detected one, so a user who has defined the instance
+% `cmr2' may use
+% \begin{verbatim}
+% \sfrac[cmr2]{7}{12}
+% \end{verbatim}
+% and get the settings from `cmr2' instead of the settings of the
+% current font family.
+% \begin{macrocode}
+\DeclareDocumentCommand \sfrac {o mom}{
+ \if_mathmode:
+ \edef\xfrac_next: {mathfam\number\fam}
+ \IfExistsInstanceTF{xfrac}{\xfrac_next: }
+ {\UseInstance{xfrac}{\xfrac_next: }}
+ {\UseInstance{xfrac}{mathdefault}}
+ {#2}{#3}{#4}
+ \else:
+ \IfExistsInstanceTF{xfrac}{#1}
+ {\UseInstance{xfrac}{#1}{#2}{#3}{#4}}
+ {\IfExistsInstanceTF{xfrac}{\f@family}
+ {\UseInstance{xfrac}{\f@family}}
+ {\UseInstance{xfrac}{default}}
+ {#2}{#3}{#4}
+ }
+ \fi:
+}
+% \end{macrocode}
