% sfmath.sty by Olaf Dietrich (odt@dtrx.de) \NeedsTeXFormat{LaTeX2e} \ProvidesPackage{sfmath}[2001/09/02 v0.2 sans serif maths] % This is a simple package for sans serif maths in documents. % % (It's not working particularly well or typographically satisfying.) % % Usage: \usepackage{sfmath} or \usepackage[OPTIONS]{sfmath} % % OPTIONS are % % * slantedGreek: for slanted uppercase Greek letters % * helvet: use Postscript Helvetica (phv) for maths (explicitly) % * cm: use Computer Modern (cmss) for maths (explicitly) % * mathrmOrig: do not change the behavior of the \mathrm command % * mathbfOrig: do not change the behavior of the \mathbf command % * mathitOrig: do not change the behavior of the \mathit command % * mathsfOrig: do not change the behavior of the \mathsf command % % % This package should work with pdflatex and produce documents % with Postscript Type 1 Fonts. If \sfdefault is changed by a % package like pslatex.sty or times.sty (obsolete) or manually % then include sfmath.sty _after_ having changed \sfdefault. % Alternatively, select the desired sans serif font with the % package option helvet or cm. % % Functionality is limited by the intention to work without additionally % defined (virtual) fonts; instead, only standard fonts are used. % CHANGES: % % v0.2: % % * New option slantedGreek for slanted greek capitals % % * Options helvet and cm to select explicitly the sans serif font % for maths. Without any of these options, the current \sfdefault % is chosen. % % * Options mathxxOrig: don't change the alphabet command \mathxx; % available for \mathrm, \mathbf, \mathit, and \mathsf % % * Provide dotlessi and dotlessj (if available) % % BUGS/LIMITATIONS/PROBLEMS: % % * In many constellations with Postscript fonts (helvet.sty, % pslatex.sty, ...) the upper-case greek letters are not chosen % correctly within \mathrm, \mathbf, \mathit, ... (because % they should be part of OT1-encoded fonts but are not included % in these standard postscript fonts). % % * Bold math symbols are not always available (e. g. with pslatex.sty) % or at least not slanted (e. g. with cmss fonts), so better don't % use bold maths with this package. % % * The set symbols \mathbb{N} or \mathbbm{N} (from bbm.sty) are not % changed. You might like to use \mathbbmss{n} (from bbm.sty). % % * Some symbols have serifish shapes (\sum, \prod, probably more) and % are not changed. % % * Lower-case greek letters are not available in sans serif shape % (they don't have real serifs, but cannot be expected to harmonize % with the sans serif latin letters). % % * Is this the Right Way to do it? Or would it be preferable to define % one or two new math _versions_ (sans, sansbold), such that formulas % are switched to sans by \mathversion{sans}? % % * some more ... % HERE WE GO: % Declare options and defaults and process options \DeclareOption{helvet}{\renewcommand{\math@sfdefault}{phv}} \DeclareOption{cm}{\renewcommand{\math@sfdefault}{cmss}} \DeclareOption{slantedGreek}{\renewcommand{\greek@shape}{sl}} \DeclareOption{mathrmOrig}{\renewcommand{\mathrm@lph}{cmr}} \DeclareOption{mathbfOrig}{\renewcommand{\mathbf@lph}{cmr}} \DeclareOption{mathitOrig}{\renewcommand{\mathit@lph}{cmr}} \DeclareOption{mathsfOrig}{\renewcommand{\mathsf@lph}{cmss}} \newcommand{\math@sfdefault}{\sfdefault} \newcommand{\greek@shape}{n} \newcommand{\mathrm@lph}{\math@sfdefault} \newcommand{\mathbf@lph}{\math@sfdefault} \newcommand{\mathit@lph}{\math@sfdefault} \newcommand{\mathsf@lph}{\math@sfdefault} \ProcessOptions % Change font for digits and "operators" (\sin, \exp, ...) % to default sans serif font \SetSymbolFont{operators}{normal}{OT1}{\math@sfdefault}{m}{n} \SetSymbolFont{operators}{bold}{OT1}{\math@sfdefault}{bx}{n} % Most special math symbols remain unmodified (and many of those % don't have serifs); however all letters (A-Z, a-z) are % explicitely changed to the sans serif version (again % default sans serif font). % % Unfortunately, there is no standard slanted+bold sans serif font % available (as Postscript Type 1 font), so try an upright % version (may be better than nothing). \DeclareSymbolFont{SFMath}{OT1}{\math@sfdefault}{m}{sl} \SetSymbolFont{SFMath}{normal}{OT1}{\math@sfdefault}{m}{sl} \SetSymbolFont{SFMath}{bold}{OT1}{\math@sfdefault}{bx}{n} \DeclareMathSymbol{A}{\mathalpha}{SFMath}{`A} \DeclareMathSymbol{B}{\mathalpha}{SFMath}{`B} \DeclareMathSymbol{C}{\mathalpha}{SFMath}{`C} \DeclareMathSymbol{D}{\mathalpha}{SFMath}{`D} \DeclareMathSymbol{E}{\mathalpha}{SFMath}{`E} \DeclareMathSymbol{F}{\mathalpha}{SFMath}{`F} \DeclareMathSymbol{G}{\mathalpha}{SFMath}{`G} \DeclareMathSymbol{H}{\mathalpha}{SFMath}{`H} \DeclareMathSymbol{I}{\mathalpha}{SFMath}{`I} \DeclareMathSymbol{J}{\mathalpha}{SFMath}{`J} \DeclareMathSymbol{K}{\mathalpha}{SFMath}{`K} \DeclareMathSymbol{L}{\mathalpha}{SFMath}{`L} \DeclareMathSymbol{M}{\mathalpha}{SFMath}{`M} \DeclareMathSymbol{N}{\mathalpha}{SFMath}{`N} \DeclareMathSymbol{O}{\mathalpha}{SFMath}{`O} \DeclareMathSymbol{P}{\mathalpha}{SFMath}{`P} \DeclareMathSymbol{Q}{\mathalpha}{SFMath}{`Q} \DeclareMathSymbol{R}{\mathalpha}{SFMath}{`R} \DeclareMathSymbol{S}{\mathalpha}{SFMath}{`S} \DeclareMathSymbol{T}{\mathalpha}{SFMath}{`T} \DeclareMathSymbol{U}{\mathalpha}{SFMath}{`U} \DeclareMathSymbol{V}{\mathalpha}{SFMath}{`V} \DeclareMathSymbol{W}{\mathalpha}{SFMath}{`W} \DeclareMathSymbol{X}{\mathalpha}{SFMath}{`X} \DeclareMathSymbol{Y}{\mathalpha}{SFMath}{`Y} \DeclareMathSymbol{Z}{\mathalpha}{SFMath}{`Z} \DeclareMathSymbol{a}{\mathalpha}{SFMath}{`a} \DeclareMathSymbol{b}{\mathalpha}{SFMath}{`b} \DeclareMathSymbol{c}{\mathalpha}{SFMath}{`c} \DeclareMathSymbol{d}{\mathalpha}{SFMath}{`d} \DeclareMathSymbol{e}{\mathalpha}{SFMath}{`e} \DeclareMathSymbol{f}{\mathalpha}{SFMath}{`f} \DeclareMathSymbol{g}{\mathalpha}{SFMath}{`g} \DeclareMathSymbol{h}{\mathalpha}{SFMath}{`h} \DeclareMathSymbol{i}{\mathalpha}{SFMath}{`i} \DeclareMathSymbol{j}{\mathalpha}{SFMath}{`j} \DeclareMathSymbol{k}{\mathalpha}{SFMath}{`k} \DeclareMathSymbol{l}{\mathalpha}{SFMath}{`l} \DeclareMathSymbol{m}{\mathalpha}{SFMath}{`m} \DeclareMathSymbol{n}{\mathalpha}{SFMath}{`n} \DeclareMathSymbol{o}{\mathalpha}{SFMath}{`o} \DeclareMathSymbol{p}{\mathalpha}{SFMath}{`p} \DeclareMathSymbol{q}{\mathalpha}{SFMath}{`q} \DeclareMathSymbol{r}{\mathalpha}{SFMath}{`r} \DeclareMathSymbol{s}{\mathalpha}{SFMath}{`s} \DeclareMathSymbol{t}{\mathalpha}{SFMath}{`t} \DeclareMathSymbol{u}{\mathalpha}{SFMath}{`u} \DeclareMathSymbol{v}{\mathalpha}{SFMath}{`v} \DeclareMathSymbol{w}{\mathalpha}{SFMath}{`w} \DeclareMathSymbol{x}{\mathalpha}{SFMath}{`x} \DeclareMathSymbol{y}{\mathalpha}{SFMath}{`y} \DeclareMathSymbol{z}{\mathalpha}{SFMath}{`z} \DeclareMathSymbol{\imath}{\mathalpha}{SFMath}{"10} \DeclareMathSymbol{\jmath}{\mathalpha}{SFMath}{"11} % Take capital greek letters from cmss; other sans serif fonts % like helvetica don't have capital greeks, so here cmss is % taken instead of \sfdefault.
