Therefore, you must include sfmath.sty after having +% changed \sfdefault, e.g., by a package such as helvet.sty or +% manually. Alternatively, use one of the font options described +% below (cm, helvet, cmbright, tx, px, or lm) in order to override +% the default sans serif font. +% +% Package OPTIONS (options marked with (+) are experimental): +% +% * slantedGreek: for slanted uppercase Greek letters +% +% * cm: use Computer Modern (cmss) for maths (explicitly) +% * helvet: use Postscript Helvetica (phv) for maths (explicitly) +% * cmbright: use CM-Bright fonts (cmbr) for maths (explicitely) +% * tx: use Postscript txfonts (tx) for maths (explicitly) +% * px: use Postscript pxfonts (tx) for maths (explicitly) +% * lm: use Latin Modern (lmss) for maths (explicitly) (+) +% +% * T1experimental: use T1 font encoding for standard maths (+) +% * AlphT1experimental: use T1 font encoding for \math*{...} commands (+) +% +% * 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 +% +% (+): Known limitations of experimental options: +% T1experimental produces a warning about the encoding of the +% operators font. +% AlphT1experimental DOES NOT WORK with uppercase Greek letters +% within the \math*{...} command! +% These options should only be used with the ec fonts. +% +% lm includes T1experimental and AlphT1experimental with the +% limitations mentioned above. +% +% RECOMMENDATION: +% use the fix-cm package instead of the experimental +% T1 options: with fix-cm.sty, the chosen ec fonts +% harmonize much better with the cm sans serif math fonts. +% Add \RequirePackage{fix-cm} _before_ \documentclass{...}. +% +% +% Some new macros are defined by sfmath.sty: +% +% * \mathsl{...}: A new math alphabet that is by default identical +% with \mathit{...}; useful in combination with the option mathitOrig. +% +% * \upOmega, \upDelta: upright versions of \Omega and \Delta; +% useful when the option slantedGreek is selected. +% +% +% More documentation can currently be found at: +% <URL:http://dtrx.de/od/tex/sfmath.html> + + +% CHANGES: +% +% v0.8: +% +% * Update documentation and add license details for CTAN upload. +% +% +% v0.7: +% +% * Add (experimental) support for latin modern (lmodern) fonts. +% +% +% v0.6: +% +% * Add some artificial intelligence to use slanted bold letters +% if available (e.g., for phv, txfonts, or pxfonts). +% Add options to select txfonts, pxfonts, and cmbright (probably +% not very useful) explicitely. +% (Thanks to Alberto Lusiani who asked for slanted bold letters.) +% +% +% v0.5: +% +% * Add experimental options for T1 font encoding of maths fonts. +% Using these options can be useful with ec fonts which look +% slightly different from the standard cm maths fonts (especially +% at large font size). About limitations see above. +% +% +% v0.4: +% +% * Add \upDelta, \upOmega command (to be a little more compatible +% with other packages that provide the slantedGreek option) +% +% +% v0.3: +% +% * Add sans serif shapes for "," and ".", "\ldotp" +% +% * Modified documentation +% +% +% 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: +% +% * Functionality is limited by the intention to work without +% additionally defined (virtual) fonts; instead, only standard +% fonts are used. +% +% * The font metrics are not adjusted to maths usage (this may +% result in typographically unsatisfying results). +% +% * 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. (This has been partially improved +% in version 0.6.) +% +% * There is a visual difference between the ec sans serif text fonts +% and the cm sans serif maths fonts, especially at larger font sizes. +% The fix-cm package might help to reduce the ugliness of the ec +% sans serif fonts and the differences between the ec text fonts +% and the cm math fonts. +% Alternatively, the experimental options T1experimental and +% AlphT1Experimental might help by using the ec fonts for maths as well. +% +% * The txfonts and pxfonts are reported to have several deficiencies +% with respect to font metrics and macro implementation; using +% these fonts is not recommended by the package author. +% +% * 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). +% +% +% TODO: +% +% * Improve documentation. +% +% * Provide LaTeX .ins/.dtx files instead of naked .sty file. +% + + +% HERE WE GO: + +% Declare options and defaults and process options + +\DeclareOption{slantedGreek}{% + \renewcommand{\greek@shape}{sl}% + \renewcommand{\greek@bold@shape}{\greek@bold@sl}% +} + +\DeclareOption{cm}{\renewcommand{\math@sfdefault}{cmss}} +\DeclareOption{lm}{\renewcommand{\math@sfdefault}{lmss}} +\DeclareOption{helvet}{\renewcommand{\math@sfdefault}{phv}} +\DeclareOption{cmbright}{\renewcommand{\math@sfdefault}{cmbr}} +\DeclareOption{tx}{\renewcommand{\math@sfdefault}{txss}} +\DeclareOption{px}{\renewcommand{\math@sfdefault}{pxss}} + +\DeclareOption{T1experimental}{\renewcommand{\math@encoding}{T1}} +\DeclareOption{AlphT1experimental}{\renewcommand{\math@lph@encoding}{T1}} + +\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{\math@encoding}{OT1} +\newcommand{\math@lph@encoding}{OT1} + +\newcommand{\mathrm@lph}{\math@sfdefault} +\newcommand{\mathbf@lph}{\math@sfdefault} +\newcommand{\mathit@lph}{\math@sfdefault} +\newcommand{\mathsf@lph}{\math@sfdefault} + + +% \math@sfGreek: Font for capital greeks: cmss or other? +% \greek@shape: Capital greeks: normal or slanted?
