\begin{document}



\maketitle



The Computer Modern font family has a sans serif typeface. However, compared to the serif typeface, it is incomplete: there are no sans serif small caps or math fonts. Furthermore, the bold slanted font is not available as an outline font.
This leads to highly unsatisfactory typography of documents that use sans serif for the body text.


The \textsf{sansmathfonts} package provides these ``missing'' fonts. Most of the usefulness of the package is in the fonts; \texttt{sansmathfonts.sty} is a small package providing \LaTeX\ support. To use it, simply say \texttt{\char`\\usepackage\char`\{sansmathfonts\char`\}} in the document preamble.

In the default (OT1) text font encoding, and also in the T1 and U font encodings, this will redefine the document's default sans serif font family from \textsf{cmss} to \textsf{xcmss}; this will make the \textsf{\textbf{\textit{bold slanted}}} and \textsf{\textsc{Caps and small caps}} fonts available via normal \LaTeX\ font commands (\verb|\textbf|, \verb|\textit| and \verb|\textsc|). If you additionally load Harald Harder's \textsf{slantsc} package, this will make \textsf{\textit{\textsc{slanted caps and small caps}}} available.

This will also switch the math fonts to sans serif:
\[\Im \mathop{\mathrm{exp}}(i\omega)=\sin(\omega) \]
If you use symbols from the \textsf{amsfonts} or \textsf{esint} packages, they will also be replaced by appropriate sans serif versions:
\[\ointclockwise \quad \mho \quad \hbar\]
By default, the commands \verb|\mathrm| and \verb|\mathsf| both produce sans serif text. To get serifed roman text, use the command \verb|\mathserif|:
\[\mathrm{mathrm}\quad\mathsf{mathsf}\quad\mathserif{mathserif}\]
\textsf{sansmathfonts} knows about the \textsf{beamer} document class and will automatically use \textsf{beamer}'s \texttt{professionalfonts} theme.

The math fonts differ slightly from Knuth's standard sans serif fonts. Specifically, for ease of reading I have chosen to put the serifs back on the uppercase I, Pi and~Xi:
\[{I}\quad\mathrm{I}\quad\mathbf{I}\quad\bm{I}\quad
\mathit{\Pi}\quad{\Pi}\quad\mathbf{\Pi}\quad
\mathit{\Xi}\quad{\Xi}\quad\mathbf{\Xi}\quad
\text{and not\quad \textsf{\font \rawfont = cmss10 \rawfont I\quad \char5\quad\char4}}\]
\textsf{Sans serif Is outside of math mode} still have no serifs unless the package option \texttt{[I]} is used; note that this option as yet only works with the OT1 and U font encodings.


Feedback is appreciated and may be sent to \texttt{origamist@gmail.com}.

\section{Package options}

\begin{itemize}
\item \texttt{[I]} The \texttt{[I]} package option puts the serifs back on the capital I even in text mode. This option only works with the OT1 and U font encodings.
\item \texttt{[onlymath]}, \texttt{[nottext]}. These options provide sans serif math but do not change the text sans serif font.
\item \texttt{[onlytext]}, \texttt{[notmath]}. These options provide sans serif text fonts and improve the behavior of \texttt{\char`\\mathsf} but do not change the default math font from roman to sans serif. You can get a similar effect by not using the \textsf{sansmathfonts} package and using the line \texttt{\char`\\renewcommand\char`\{\char`\\sfdefault\char`\}\char `\{xcmss\char`\}}
or
\texttt{\char`\\renewcommand\char`\{\char`\\sfdefault\char`\}\char `\{cmsmf\char`\}}
in the document preamble.
\end{itemize}

\section{Files in this package}\label{sec:files}

109 of the new fonts listed in \autoref{sec:fonts} come in three files each: the \TeX\ Font Metric files (extension \texttt{.tfm}), the Type 1 font file (extension \texttt{.pfb}), and Metafont source file (extension \texttt{.mf}).

The 9 \textsf{cmssxi} and \textsf{cmssbx} fonts come as \texttt{.pfb} files only, as the MetaFont sources are already part of the \TeX\ Live distribution (see also the \textsf{sauter} package at \texttt{\href{http://www.ctan.org/tex-archive/fonts/cm/sauter} {http:/\slash www.ctan.org\slash tex-archive\slash fonts\slash cm\slash sauter}}).

The 28 \textsf{cmsmf} fonts are almost identical to their \textsf{cmss} counterparts. Thus, these fonts are provided as \emph{virtual} fonts, and so come in five parts: the virtual font file (\texttt{cmsmf.vf}), the \TeX\ Font Metric file (\texttt{cmsmf.tfm}), and the font \textsf{cmsmfIPiXi} containing only the altered letters \cmsmf{I}, \cmsmf{\char4} and \cmsmf{\char5} (and \cmsmf{\textsc{i}}, in the small caps fonts); this font comes as MetaFont source (\texttt{cmsmfIPiXi.mf}), \TeX\ font metric (\texttt{cmsmfIPiXi.tfm}) and Type 1 font (\texttt{cmsmfIPiXi.pfb}).

In addition, this package should come with the following 29 supplementary Metafont source files:

\begin{itemize}
\item \texttt{eczi.mf}
\item \texttt{eczo.mf}
\item \texttt{eczx.mf}
\item \texttt{eczz.mf}
\item \texttt{sans-amsya.mf}
\item \texttt{sans-amsyb.mf}
\item \texttt{sans-asymbols.mf}
\item \texttt{sans-bigdel.mf}
\item \texttt{sans-bigint.mf}
\item \texttt{sans-bigop.mf}
\item \texttt{sans-bsymbols.mf}
\item \texttt{sans-calu.mf}
\item \texttt{sans-csc.mf}
\item \texttt{sans-greekl.mf}
\item \texttt{sans-greeku.mf}
\item \texttt{sans-IPiXi.mf}
\item \texttt{sans-IPiXicsc.mf}
\item \texttt{sans-mathex.mf}
\item \texttt{sans-mathint.mf}
\item \texttt{sans-mathsl.mf}
\item \texttt{sans-mathsy.mf}
\item \texttt{sans-roman.mf}
\item \texttt{sans-romanu.mf}
\item \texttt{sans-romms.mf}
\item \texttt{sans-slantms.mf}
\item \texttt{sans-sym.mf}
\item \texttt{sans-symbol.mf}
\item \texttt{sans-xbbold.mf}
\item \texttt{sansfontbase.mf}
\end{itemize}

This package should also come with the following 11 \LaTeX\ Font Definition files:

\begin{itemize}
\item \texttt{omlcmssm.fd}
\item \texttt{omscmsssy.fd}
\item \texttt{omxcmssex.fd}

\item \texttt{ot1cmsmf.fd}
\item \texttt{ot1xcmss.fd}
\item \texttt{t1xcmss.fd}

\item \texttt{ucmsmf.fd}
\item \texttt{ussesint.fd}
\item \texttt{ussmsa.fd}
\item \texttt{ussmsb.fd}
\item \texttt{uxcmss.fd}
\end{itemize}

Finally, it should come with the font map file, LaTeX package, and documentation:

\begin{itemize}
\item \texttt{sansmathfonts.map}
\item \texttt{sansmathfonts.sty}
\item \texttt{sansmathfonts.tex}
\item \texttt{sansmathfonts.pdf}
\end{itemize}

% The subfolders should contain:

% doc: 2 files
% map: 1 file
% tex: 12 files

% New Type 1 fonts: 	137
% Old fonts as Type 1: 	9
% Virtual fonts:		28
% Supplementary .mf:	29

% source: 166 files (=137+29)
% tfm: 165 files	(=137+28)
% type1: 146 files  (=137+9)
% vf: 28  			(=28)

This work has the LPPL maintenance status ``maintained''.

Almost all of the Metafont files in this package are very closely based on existing files in the 2011 \TeX\ Live distribution; see comments near the start of the individual files for notes on their sources. Also, note that the 
files
\begin{itemize}
\item \texttt{cmssxi8.pfb}
\item \texttt{cmssxi9.pfb}
\item \texttt{cmssxi10.pfb}
\item \texttt{cmssxi12.pfb}
\item \texttt{cmssxi17.pfb}
\item \texttt{cmssbx8.pfb}
\item \texttt{cmssbx9.pfb}
\item \texttt{cmssbx12.pfb}
\item \texttt{cmssbx17.pfb}
\end{itemize}
were derived from unedited MetaFont source files in the \textsf{sauter} package using mftrace 1.2.18 and Fontforge. 

\section{Revision history}

\begin{itemize}
\item
April 2013: Original upload
\item
February 2017: Corrected the font names in \texttt{sansmathfonts.map}; this allowed the package to be used correctly with \textsf{dvips}.  
\item
April 2019: Fixed a bug in the file \texttt{ucmsmf.fd} that prevented the \texttt{[I]} package option from working correctly; rewrote most of the \texttt{.fd} files to allow fonts to be loaded at arbitrary sizes; changed maintenance status from ``author-maintained'' to ``maintained''.
\item
June 2019: Rewrote the file \texttt{omxcmssex.fd} to allow the math extended characters to be loaded at arbitrary sizes.
\item
June 2021: Rewrote the OT1, T1, and U font definition files to substitute bold-extended fonts for bold fonts as necessary. Added some package errors and warnings if the document font encoding is not supported.
\end{itemize}
