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: +% $8/13$. +% \endgroup +% +% +% \section{The Template Interface} +% +% \begin{TemplateInterfaceDescription}{xfrac} +% +% \TemplateArgument{1} +% {The numerator} +% +% \TemplateArgument{2} +% {The separator} +% +% \TemplateArgument{3} +% {The denominator} +% +% \TemplateSemantics +% +% Typesets arguments 1 and 3 separated by argument 2, which in text +% mode by default is a \emph{solidus}. This is taken from +% \package{textcomp} where it is denoted \cs{textfractionsolidus}. +% This is the character used for the ready made split level +% fractions such as \textonehalf---except in the (European) Computer +% Modern fonts. In math mode a \emph{virgule} is used instead as +% this is more appropriate and it is always available in the math +% fonts. The solidus is a text symbol only. +% +% \end{TemplateInterfaceDescription} +% +% \begin{TemplateDescription}{xfrac}{text} +% +% \TemplateKey{numerator-font}{n} +% {Font family specification to use for the numerator.} +% {\cs{f@family}} +% +% \TemplateKey{numerator-format}{f1} +% {Action to be taken on the numerator.} +% {Process argument unchanged} +% +% \TemplateKey{slash-symbol}{n} +% {The separator symbol.
