For example if \texttt{?} is already active in the document, in \verb|$?\hbox{?}$| the first \texttt{?} will use the \texttt{mathastext} definition, whereas the second one will use its original definition as active character. Let's try: \begin{verbatim} \catcode`\?=\active \def?{X} $?\mathtt{?}\hbox{?$\mathbf{?}$}$ \end{verbatim} The result is: \catcode`\?\active\def?{X}$?\mathtt{?}\hbox{?$\mathbf{?}$}$. However, after \verb|\MTnonlettersdonotobeymathxx|,\MTnonlettersdonotobeymathxx{} we get: $?\mathtt{?}\hbox{?$\mathbf{?}$}$. The original definition of the active character has been used everywhere, as expected.

With hundreds of free text fonts packaged for \LaTeX{} and only a handful of math ones, chances are your favorite text font does not mix so well with the available math ones; \mst may then help. Here is an example with Latin Modern typewriter proportional: {\advance\leftskip.1\linewidth\advance\rightskip.1\linewidth \MTversion{lmvtt} Let $(X,Y)$ be two functions of a variable $a$.

But perhaps we insist on obeying the standardized habits: {\advance\leftskip.1\linewidth\advance\rightskip.1\linewidth \MTversion{times} Let $(X,Y)$ be two functions of a variable $a$.

This document uses the |LGR| encoded fonts |cmtt|, |cmss|, and |txr|, which are part of standard \TeX{} distributions.\footnote{The first two are available (with no need to load explicitely any package in the document) via the combination |cbfonts| (|cbgreek-complete|) \& |babel|, and the |LGR| encoded |txr| font (again no package loading is necessary) is part of the files of the |txfonstb| package.} % \href{http://mirrors.ctan.org/help/Catalogue/entries/cbgreek-complete.html}{cbfonts}, % \href{http://mirrors.ctan.org/help/Catalogue/entries/txfontsb.html}{txfontsb}. \subsection{Overview} \subsubsection{Basic use} The initial ideology of \mst was to produce mathematical texts with a very uniform look, not separating math from text as strongly as is usually done. As soon as one tries out other fonts for text than the Computer Modern ones one realizes how extremely ``thin'' are the default \TeX{} fonts for mathematics: they definitely do not fit well visually with the majority of text fonts. With \mst one can get one's (simple\dots{} or not) mathematics typeset in a manner more compatible with the text, without having to look for an especially designed font. Here is a minimal example of what may go into the preamble: \begin{verbatim} \usepackage[T1]{fontenc} \usepackage{times} \usepackage[italic]{mathastext} \end{verbatim} All letters, digits, and punctuation signs inside math mode will then be typeset in Times.\footnote{let's do as if we did not know the excellent |txfonts| package which employs Times for text and has a very complete math support, including many additional mathematical glyphs in comparison to the CM fonts.} The exact list of characters concerned by \mst is a subset of the basic |ASCII| set: \begin{framed}\centering \begingroup\color{joli}\bfseries {abcdefghijklmnopqrstuvwxyz}\\ {ABCDEFGHIJKLMNOPQRSTUVWXYZ}\\ {0123456789}\\ \DeleteShortVerb{\|}% {!\,?\,\raisebox{-.3\height}{*}\,,\,.\,:\,;\,+\,\textendash\,=\,(\,)\,[\,]\,/\,\#\,% \$\,\%\,\&\,<\,>\,|\,\{\,\} {\color{black}\mdseries and }\char92}\endgroup\MakeShortVerb{\|} \end{framed} As one can see, this is a very limited list! some possibilities are offered by \mst for Greek letters and will be described later. The text characters {}'{} and {}-{} are not used, and the asterisk is done optionally: \begin{itemize} \item the derivative sign ${}'$ is left to its default as the text font glyph {}'{} is not, as a rule, a satisfying alternative.\footnote{|v1.2| adds a customizable tiny space before ${}'$ to separate it from the previous letter, this is really needed when using upright letters in math mode with the CM derivative glyph.{\MTversion{upright}\sffamily\MTprimeskip{.5mu}% Compare $f'$ with \MTprimeskip{0mu}$f'$.} } \item for the minus sign \mst uses the endash character \textendash, if available, and not the hyphen character -, \item the option §asterisk§ is necessary for \mst to replace the binary math operator $*$ (and the equivalent control sequence \cs{ast}) with a version which uses the text asterisk * suitably lowered\footnote{the amount of lowering can be customized.} (and with the correct spaces around it as binary operator). The reason for making it optional is that after this |$R^*$| or |$R^\ast$| do not work and have to be written |$R^{*}$| or |$R^{\ast}$|. \end{itemize} Nothing is changed to the ``large'' math symbols, except for $\defaultprod$ and $\defaultsum$ in inline math which, like here: $\prod\sum$, will be taken from the Symbol Font if option §symbolmisc§ was used. \subsubsection{sans in math} The following set-up often gives esthetically pleasing results: it is to use the sans-serif member of the font family for math, and the serif for text. \begin{verbatim} \renewcommand\familydefault\sfdefault \usepackage{mathastext} \renewcommand\familydefault\rmdefault \begin{document} \end{verbatim} \subsubsection{always load \mst last} As said already none of the ``large'' math symbols is modified in any way by \mst. Only loading some math font packages such as |fourier|, |kpfonts|, |mathabx|, |mathdesign|, |txfonts|, |newtxmath|, etc\dots{} will change them. Think of loading these packages before \mst, else they might undo what \mst did. The more common symbols can be taken from the Symbol font (option §symbolmisc§, or §symbolmax§ to get also the Greek letters from Symbol). \subsubsection{option \blueit{LGRgreek}} There is the issue of Greek letters. Sometimes the text font has Greek glyphs, in |LGR| encoding (this will be mentioned in the documentation of the font package). Then option §LGRgreek§ tells \mst to pick up these Greek letters. And it is possible to specify whether the Greek letters should be upright, or ``italic''.\footnote{a more detailed discussion comes next. Note that the default CM and its replacement Latin Modern for european languages are (transparently to the user) extended with |LGR| encoded fonts from the |cbfonts| (|cbgreek-complete|) package.} Of course it is always possible to leave the responsability to set up Greek letters in math mode to packages loaded previously to \mst. % \href{http://mirrors.ctan.org/help/Catalogue/entries/cbgreek-complete.html}{cbfonts} \subsubsection{avoid \texorpdfstring{\texttt{OT1}}{OT1} encoding} We specified in our minimal working example a |T1| encoding (|LY1| would have been ok, too) because the default |OT1| does not have the {\color{joli}\DeleteShortVerb{\|} $\mathord{<}\,\mathord{>}\,\mathord{|}$\,\{\,\}} and {\color{joli}$\backslash$\MakeShortVerb{\|}} glyphs. If \mst detects |OT1| as the default encoding it will leave these characters to their defaults from the math fonts.\footnote{the §subdued§ option, described next, acts a bit otherwise, it forces, contrarily to its usual low-key character, the replacement of |OT1| by |T1| for the fonts ultimately used with letters and digits in math mode.} \begin{framed} If \mst detects the obsolete |OT1| encoding it does not do anything with \DeleteShortVerb{\|}<, >, |, \{, and \} which (except for monospace fonts) are not available in that encoding.\MakeShortVerb{\|} To fully benefit from \mst it is recommended to use some other encoding having these glyphs such as |T1| or |LY1|. \end{framed} \subsection{Main options} \subsubsection{The \blueit{italic} option} In the initial version |1.0|, the Latin letters in mathematical mode assumed the exact same shape as in text mode, and this meant, generally speaking, that they would turn up upright. Doing this gives a very uniform look to the document, so that one has to make an effort and read it with attention, and this was one of the design goals of \mst. Nevertheless, soon after I posted the initial version of the package to CTAN, I was overwhelmed by numerous\footnote{this means ``more then one.''} questions\footnote{I thank in particular Tariq~\textsc{Perwez} and Kevin~\textsc{Klement} for their kind remarks (chronological order).} on how to have the letters be in italic shape. The default is still, as in version |1.0|, for everything to be in upright shape, but it suffices to pass to the package the option §italic§ to have the Latin letters in math mode in italic shape.\footnote{more precisely stated, the value of \cs{itdefault} is used.} There is also an option §frenchmath§ to make the uppercase letters nevertheless upright, because this is the way of traditional French mathematical typography.\footnote{more precisely stated, the value of \cs{shapedefault} is used.} \subsubsection{The \blueit{defaultmathsizes} option} The default sizes give for subscripts of subscripts barely legible glyphs (author's opinion!). So \mst makes more reasonable choices. It also redefines \cs{Huge} and defines a \cs{HUGE} size, copied from the |moresize| package. To cancel all of this use option §defaultmathsizes§. \subsubsection{The \blueit{subdued} option} This option was introduced in |v1.15|. It provides a manner to switch on the \mst-\emph{ification} only for limited portions of the document, with the help of the mechanism of math versions. Without the §subdued§ option, the \emph{mathastextification} applies by default to the whole of the document (and one may also define additional math versions in the preamble); with the §subdued§ option the \emph{mathastextification} is done only in \emph{math versions} distinct from the standard and bold ones. The previous description is in fact a bit optimistic: \mst was not written initially in order to allow its action to be completely cancelled, and achieving this would require a complete rewrite of large portions of the code. In order to really have the displayed math (almost) as if \mst had not been loaded, one must at a minimum also use the option §defaultmathsizes§. This does not quite suffice, because, for example, the colon, the dot, and the minus sign belong in the default \LaTeX{} math mode set-up to three distinct fonts whereas \mst will pick (even subdued) the three of them in the same font, and although it will make a reasonable choice of this font, this is not a return to the previously prevailing situation. And then arbitrary packages could have done arbitrary things... so to be on the safe side one needs the §basic§ option which limits the mathastextification to letters and digits (and should also be accompanied by §defaultimath§ which prevents redefinition of the \cs{imath} macro, and §nohbar§ which prevents redefinition of the \cs{hbar} macro\dots). And even then, in some circumstances, this will still not suffice; for example the \emph{euler} package puts the digits in the same font as the Latin letters in math mode, but the subdued \mst will pick them up in the same font as used in operator names, and in the case of the \emph{euler} package, this is the main document font. So, even subdued, \mst still kicks. But, as I think is illustrated by the examples given at the start of this document, the §subdued§ option has its utility, and works reasonably well. Furthermore, the §subdued§ action does \emph{not} extinguish package options §eulergreek§, §symbolgreek§ or §symbol§. But §LGRgreek§ is receptive to it. \subsection{Math versions} \LaTeX{} has the concept of \emph{math versions}, but most font packages do not define any such version beyond the default normal and bold (that they possibly customize to use such or such math font). The package |unicode-math| for unicode engines fruitfully uses this concept. \mst uses math versions in order to allow the math mode fonts (for letters, digits, punctuation and a few other ascii symbols) used in the different parts of the document to be kept in sync with the text fonts. However the other math symbols (sums, products, integrals, logical signs, etc\dots) will be the same throughout the document as it is not in \mst power to modify them. There are some possibilities to use different sets of fonts for the Greek letters, though. The present document illustrated the use of various fonts, here is its preamble (slightly stripped-down): \begin{center} \begin{minipage}{.8\linewidth} \begin{verbatim} \usepackage{lmodern} \usepackage[T1]{fontenc} \usepackage[subdued,italic,defaultmathsizes]{mathastext} \MTDeclareVersion[n]{lmvtt}{T1}{lmvtt}{m}{n} \usepackage{newcent} \Mathastext[newcent] \usepackage{times} \Mathastext[times] \usepackage[scaled]{helvet} \renewcommand\familydefault\sfdefault \Mathastext[helvet] \begin{document}\MTversion{normal} \end{verbatim} \end{minipage} \end{center} Let us examine this code: it uses once the command §\MTDeclareVersion§ and three times the command §\Mathastext§, thus defining four |math versions|\footnote{|math versions| are discussed in the document |fntguide.pdf| from your \TeX{} distribution.}: |lmvtt|, |newcent|, |times|, and |helvet|. The names can be taken arbitrarily (they only need to be suitable arguments to the \LaTeX{} \cs{DeclareMathVersion} command which is invoked internally, so no spaces in the names). Two additional math versions preexist: the |normal| and |bold|, which, because there was the §subdued§ option, were left untouched by \mst. Once these |math versions| are defined, §\Mathastextversion\{name\_of\_version\}§, or equivalently §\MTversion\{name\_of\_version\}§ in the body of the document enacts the font switches. As is usual with \LaTeX{} one can limit the scope to the inside of a group, or also switch back to the main set-up through issuing \cs{Mathastextversion\{normal\}}. When \cs{Mathastext} is used in the preamble, it records the current font defaults and (except for the |normal| and |bold| versions under the §subdued§ regime) sets up the math font to be used in that version to be the text font as found in \cs{familydefault}. But it is still possible for a \mst-declared math version to have distinct fonts for text and math: \begin{enumerate} \item in the body of the \TeX{} source, an optional argument (the name of a \mst-declared math version) to \cs{MTversion} is allowed, and for example we used in the source of this document \cs{MTversion[newcent]\{helvet\}} meaning ``New Century Schoolbook for the text and Helvetica for the math.'' \item there are preamble-only commands \cs{MTencoding}, \cs{MTfamily}, \cs{MTseries}, \cs{MTshape}, \cs{MTlettershape} which tell \mst what to do (for math \emph{only}) in each math version declared \emph{afterwards}, independently of the text fonts. \end{enumerate} In the body of the document the \LaTeX{} command \cs{mathversion}\marg{version\_name} will change only the fonts used in math mode. It is recommended to use instead the package command \csb{mathastextversion} (or its synonyms \csb{MTversion}, \cs{Mathastextversion}, \cs{MTVersion}), with a mandatory argument \marg{version\_name}. It \begin{itemize} \item checks in case the §subdued§ option was specified whether the asked-for math version is \meta{normal} or \meta{bold}, and adapts the following to that case, \item sets the font which will be used in math mode for letters (including math operator names), digits, punctuations and other ascii symbols, \item sets the font of the document text (if another version name is additionally passed as optional argument, it uses instead the corresponding font for text), \item resets the |\(family,rm,sf,tt)default|s to their values as registered at the time of definition of the version, \item (see section \ref{sec:extraskips}) resets the user-defined extra spaces after the symbols $\exists$, $\forall$ and before the derivative ${}'$ to the values as decided in the preamble on a \emph{per version} basis, \item (see section \ref{sec:ic}) checks if the used font is upright and then activates the automatic insertion of italic corrections after each letter in math mode, \item (see section \ref{sec:mathxx}) makes the math operator names as well as the `easy' non letter characters (and the asterisk) obey the math alphabets, \item does some additional set up for Greek letters when the §LGRgreek§ option was used. \end{itemize} The scope is limited to the current \LaTeX{} environment or group. It is sometimes not compatible with \mst to load a font package after it, as the font package may contain instructions which will modify the math set-up. This may be a bit hidden to the user: for example the |epigrafica| package loads |pxfonts|. Hence it will interfere with \mst if it is loaded after it.\footnote{may typically give a `too many math alphabets' error message.} But one can use instead |\renewcommand{\rmdefault}{epigrafica}|,\footnote{sometimes one needs to look in the |.sty| file of the font package to figure out the font name (it is rarely as |epigrafica|, the same as the package name), and, if one does not know the arcanes of finding |.fd| files in one's \TeX{} distribution, one should look at the log file of a test document to see if for example |T1| is available for that font; for |epigrafica| it is not, only |OT1| and |LGR| are possible.} followed with \cs{Mathastext}, or also |\MTfamily{epigrafica}\Mathastext| which will only change the font in math. To use |epigrafica| for Greek in math mode one can use the package option §LGRgreek§ and the command |\MTgreekfont{epigrafica}\Mathastext|. Or \cs{usepackage}|{epigrafica}| followed with |\usepackage[LGRgreek]{mathastext}|. \subsection{Extended scope of the math alphabets commands} \label{sec:mathxx} \begingroup \MTversion{italic}\renewcommand\familydefault\sfdefault % il faudra peut-être que j'annule cette façon qu'à mathastext de tripatouiller % \familydefault... \makeatletter\let\mst@doasterisk\relax\makeatother Ever since the initial version of the package, some characters usually unaffected by the math alphabet commands \cs{mathbf}, \cs{mathtt}, \cs{mathsf}\dots{} are declared to be of `variable family type', in order for them to obey these commands: for example the hash sign $\#$ gives $\mathbf{\#}$ if input as |$\mathbf{\#}$| (\mst, especially in its beginnings, wanted as many characters as possible to be picked up from the text font and to behave similarly to letters and digits). So it was especially frustrating that mathematical characters such as $+$, or $<$, or $]$ could not be declared of `variable family' (in addition to being picked up in the text font) as this would, for reasons of the inner workings of \TeX{}, not be compatible with the automatically inserted spaces around them. A revolutionary ;-) novelty is introduced with version |1.2| of the package: \begin{enumerate} \item the pre-declared or user-declared (using the |amsmath| \cs{DeclareMathOperator} or equivalent) operator names obey the math alphabet commands,\footnote{contrarily to the next feature, this one is not likely to create incompatibilities with other packages, so it is activated by default.} \item and, \emph{optionally}, all non alphabetical characters treated by \mst, \emph{i.e.}, if not disabled by options, ${!}\,{?}\,{,}\,{:}\,{;}\,{+}\,{-}\,{=}\,{(}\,{)}\,{[}\,{]}\,{<}\,{>}\,{\{}\,{\}}$, the asterisk $*$, and $.\,/\,\vert\,\backslash\,{\#}\,{\$}\,{\%}\,{\&}$\footnote{% ${\#}\,{\$}\,{\%}\,{\&}$ obey the math alphabets since the initial version of \mst; the dot $.$, the slash $/$, the vertical bar $\vert$ and the backslash $\backslash$ do not have specific spacings inserted by \TeX{} around them, and the procedure is then not a devilish one, this is why it is made the default for these characters which are listed apart. The math symbols \cs{mid} (which is $\vert$ with type \cs{mathrel}) and \cs{setminus} ($\backslash$ with type \cs{mathbin}) are counted among the `hard' cases, not the `easy non-letters'.} will also obey the math alphabet commands (when not used as delimiters). The important thing is that the spaces added by \TeX{} before and after are not modified. \end{enumerate} Let us compare, for example, the new behavior of \cs{mathtt} and \cs{mathbf} \MTmathoperatorsobeymathxx\MTnonlettersobeymathxx\MTeasynonlettersobeymathxx \[ \mathtt{(\sin(n!)<\cos(m-p)?)}\qquad \mathbf{[\sin(x+y)=\cos(z-t)]}\] with the traditional default behavior: \MTmathoperatorsdonotobeymathxx\MTnonlettersdonotobeymathxx \MTeasynonlettersdonotobeymathxx \[ \mathtt{(\sin(n!)<\cos(m-p)?)}\qquad \mathbf{[\sin(x+y)=\cos(z-t)]}\] The first feature is activated by default, except of course for the normal and bold math versions when the package was given the \emph{subdued} option. The second feature is \emph{off} by default for the characters listed first. It is \emph{on} for the `easy' cases ${\#}\,{\$}\,{\%}\,{\&}\,.\,/\,\vert\,\backslash$ (activating the feature for them puts no constraint on the user input and should not be too upsetting to other packages), and also for $*$ but only if this was required explicitely by the option §asterisk§, as the user then is supposed to know that |$R^*$| is no valid input anymore and should be replaced by |$R^{*}$|. The remaining `hard' cases create similar constraints, which will be commented more upon next. The relevant commands are\\ \mbox{}\hspace{2cm}\csb{MTmathoperatorsdonotobeymathxx}\\ \mbox{}\hspace{2cm}\csb{MTnonlettersdonotobeymathxx}\\ \mbox{}\hspace{2cm}\csb{MTeasynonlettersdonotobeymathxx}\\ for deactivation and \\ \mbox{}\hspace{2cm}\csb{MTmathoperatorsobeymathxx}\\ \mbox{}\hspace{2cm}\csb{MTnonlettersobeymathxx}\\ \mbox{}\hspace{2cm}\csb{MTeasynonlettersobeymathxx}\\ for activation.\footnote{these commands are to be used outside of math mode. Their scope is limited to the current \LaTeX{} environment or group. They use the \cs{everymath} and \cs{everydisplay} mechanism so if the document needs to modify these token lists it has to do so in a responsible manner, extending not annihilating their previous contents.} \footnote{when in subdued mode, the math alphabets are the default ones, not the ones modified by \mst to use the document text fonts. As a result, matters of font encodings may then give unexpected results, for example for $-$. On the present document page we switched to a math version to escape from the |subdued| mode and avoid the problem with \cs{mathbf\{-\}} giving in the normal (subdued) math version {\MTversion{normal}\MTnonlettersobeymathxx$\mathbf-$\sffamily, when `non-letters' are declared to obey math alphabets.}} \begin{framed} \textbf{Important:} the package does \cs{MTnonlettersdonotobeymathxx} by default. The reason is that activating the mechanism adds some constraints to the way things must be input, adding |\usepackage{mathastext}|{}\cs{MTnon\-letters\-obey\-mathxx} to a pre-existing document might well create errors: All these characters treated by \mst, such as |?|, |[|, |<| now represent (in math mode only!) \emph{two} `tokens' and this will utterly confuse \TeX{} if some precautions are not taken: |$x^?$|, |$R^+$| or |$\mathopen$| \emph{must} now be coded as |$x^{?}$|, |$R^{+}$| and |$\mathopen{<}A\mathclose{>}$| (the rule is to do as if |?|, |+|, |<| or |>| were each really \emph{two} characters). Even if this rule is respected in the document source, it is still a possibility that incompatibilities with other packages will arise because \mst does a `mathematical activation' of the characters which could be unexpected and unchecked for by other packages. This is precisely the case with the |amsmath| package, and the problem goes away by just making sure that |amsmath| is loaded before \mst{} (generally speaking, \mst should be loaded last after all packages dealing with math things). \end{framed} The brace control sequences |\{| and |\}| have their own (supplementary) switch, which is (even) less activated by default. The reason is that after \csb{MTexplicitbracesobeymathxx}, they regrettably can not be used anymore as delimiters: |\big\{| or |\big\}| cease to function and must be replaced by |\big\lbrace| and |\big\rbrace|. But \MTmathoperatorsobeymathxx\MTnonlettersobeymathxx\MTexplicitbracesobeymathxx we can now enjoy $\mathtt{\{a, a>b\}}$, $\mathbf{\{a, a>b\}}$, $\mathsf{\{a, a>b\}}$, or even $\mathnormalbold{\{a, a>b\}}$.\footnote{this last example uses the \cs{mathnormalbold} additional alphabet defined by \mst.} There is no such restriction with $($, $)$ or the brackets $[$, $]$. When used as delimiters though, they will become again unreactive to the math alphabets: the same applies to $<$ and $>$ or to any of the other characters such as the slashes $/$, $\backslash$, when they are used as delimiters. This is a rather obvious restriction except possibly for the smallest size delimiters (the so-called `small variants'), as all other sizes will be anyway absent from the text fonts. Even the small variants may not be really available in the text fonts: for example the standard $<$ used as a delimiter is in \LaTeX{} a \cs{langle}: $\langle$. With standard \LaTeX{} |$\left< x\right>$| gives $\langle x\rangle$. Actually, \mst does try to pick up most of the `small variants' in the text font: |$\left$| gives $\left$ (but |$\left$| gives $\left$.) If you don't like that use the option §nosmalldelims§ (it is indeed perhaps a bit strange to have $\left< x\right>$ next to $\left< X\right>$, again before blaming me, consider using §nosmalldelims§.) At any rate, whether `small' or not, delimiters are not under the extended law of math alphabets, this is a general rule of the way \mst manages these things. Examples: |\mathbf{}| gives $\mathbf{}$. |\mathbf{\left}| gives $\mathbf{\left}$. |\mathbf{\mathopen{<}a,b \mathclose{>}}| gives $\mathbf{\mathopen{<} a,b \mathclose{>}}$. The \LaTeX{} standard behavior for |\mathbf{\mathopen{<}a,b\mathclose{>}}| is \endgroup $\mathbf{\mathopen{<} a,b \mathclose{>}}$. \subsection{Italic corrections} \label{sec:ic} \begingroup % \showboxbreadth=\maxdimen % \showboxdepth=\maxdimen \fboxsep0pt\fboxrule.1pt With the §italic§ option the letters in math will be generally in italic shape (and, normally, upright in operator names). For the built-in placement routines of \TeX{} in math mode to work as well as they usually do, the characters from the math italic font obviously should have their bounding boxes wide enough for the glyphs not to collide with other symbols. A letter from a text italic font such as \emph{f} extends way out of its declared bounding box; let us compare the bounding boxes\footnote{let's be honest, we are lying here about what exactly the first of these is bounding; this is explained later!} for the letter $f$ in the math italic font to the one from the text italic font: \fbox{$f$} vs. {\itshape\fbox{f}}. This could make us think that attempting to use in math a text italic font will lead to disaster. Well, surprisingly the situation is not that bad. Sure |$f(x)$| is wider with the standard math italic \fbox{$f(x)$} (\setbox0=\hbox{$f(x)$}\texttt{\the\wd0}) than it is with the text italic font used in math:\footnote{we used simply \texttt{\$\string\mathit\{f(x)\}\$}.} \fbox{$\mathit{f(x)}$} (\setbox0=\hbox{$\mathit{f(x)}$}\texttt{\the\wd0}) but we should be surprised that our text italic {\itshape f} did not end up even closer to the opening parenthesis. Why is it so? The explanation is that \TeX{} uses in such a situation the \emph{italic correction} for the letter {\itshape f}. The italic correction also exists and is used for the math italic font, it was inserted in |$f$| without us having to ask anything. Its value is \texttt{1.17865pt} for the math italic $f$ and \texttt{1.8919pt} for the text italic \emph{f}.\footnote{these values are for the Latin Modern fonts of course.} With the italic corrections included our bounding boxes are indeed more alike: \fbox{\usefont{OML}{lmm}{m}{it}f\/} vs \fbox{\itshape f\/}. Without the italic corrections\footnote{here we give correctly the bounding box for the math italic $f$... without its italic correction!} it is \fbox{\usefont{OML}{lmm}{m}{it}f} vs \fbox{\itshape f}. I said that |$f$| included the italic correction automatically, but if we tell \TeX{} to use the text italic in math, and typeset the alphabet, we obtain something exactly identical to typing the letters in text, hence without any italic correction:\par {\leftskip2cm\rightskip5cm% \noindent{\itshape abcdefghijklmnopqrstuvwxyz}\hfill\rlap{\texttt{text italic in text}}\break $\mathit{abcdefghijklmnopqrstuvwxyz}$\hfill \rlap{\texttt{text italic in math}}\break $abcdefghijklmnopqrstuvwxyz$\hfill \rlap{\texttt{math italic in math}}\break {\usefont{OML}{cmm}{m}{it}abcdefghijklmnopqrstuvwxyz}\hfill \rlap{\texttt{math italic in text}}\par} Where are our italic corrections gone? the last line was done with \cs{usefont\{OML\}\{lmm\}\{m\}\{it\}} and confirms that italic corrections have been used for the math italic in math. Turning to the \TeX book (and its Appendix G) we learn that in such circumstances, for the italic corrections to be put in from the font, one of its parameters, the interword space (aka \cs{fontdimen2}), should be zero. It is indeed zero for the math italic font, not for the text italic. It is possible to make \TeX{} believe it is. Doing so, we obtain in math mode with the text italic:\par {\leftskip2cm\rightskip5cm% \noindent{\mathastextversion{italic}% $\xdef\mstrestorefontdimen{\fontdimen2\textfont\symmtletterfont= \the\fontdimen2\textfont\symmtletterfont}% \fontdimen2\textfont\symmtletterfont=0pt% abcdefghijklmnopqrstuvwxyz$}\hfill\rlap{\texttt{text italic in math}}\break $abcdefghijklmnopqrstuvwxyz$\hfill\rlap{\texttt{math italic in math}}\par} We saw that the italic correction was taken into acount automatically (independently of the value of the interword space font parameter) in expressions such as |$f(x)$|. Another clever thing done by \TeX{} is to use it for the placement of superscripts; the next examples systematically use the text italic in math. We see that {\mathastextversion{italic}$\mstrestorefontdimen f^j$} is very different from $\hbox{\itshape f}^j$... where the latter was coded with |$\hbox{\itshape f}^j$|. The inputs |$\mathit{\hbox{\itshape f\/}^j}$| and |$\mathit{f^j}$| give almost identical results: \fbox{$\mathit{\hbox{\itshape f\/}^j}$} vs. \fbox{$\mathit{f^j}$}. Close examination reveals that the horizontal spacing is exactly identical, however the exponent in the second case is a bit lower. Anyway, the point is that in the second case the italic correction for $\mathit f$ was indeed used. Subscripts are another matter: they do \emph{not} take into account the italic correction. For example |$\mathit{f_i}$| gives the same horizontal positions as |$\mathit{\hbox{\itshape f}_i}$|: $\mathit{f_i}$ vs. $\mathit{\hbox{\itshape f}_i}$. Printing them one on another gives \rlap{$\mathit{f_i}$}$\mathit{\hbox{\itshape f}_i}$ and reveals (use the zoom of your viewer!) that only the vertical placement was affected, not the horizontal placement. We learn in Appendix G of the \TeX book that the italic correction is used for the horizontal shift of the superscript with respect to the position of the subscript: $\mathit{f_i^j}$, or, going back now to the the standard math italics $f_i^j$. In the next paragraphs we use $f_i^i$ for more accurate comparison of the positioning of the sub- and superscript. If we try something like this: |${f\/}_i^i$| we obtain ${f\/}_i^i$. Our overlapping game with |\rlap{$f_i^i$}${f\/}_i^i$| gives \rlap{$f_i^i$}${f\/}_i^i$. We discover that the effect of the explicit italic correction has mainly been to translate the subscript horizontally to be positioned exactly below the superscript!\footnote{there are also some tiny vertical displacements of the sub- and superscripts.} We most probably do \emph{not} want this to happen for our indices and exponents in math mode. So perhaps we can rejoice in how astute \TeX{} has been in judiciously using the italic correction data, and there seems to be no need into fiddling with this algorithm which seems to work well even when applied to a text italic font. Actually we may even be of the opinion that the text italic version $\mathit{f_i^i}$ is a bit better-looking than the true math italic $f_i^i$ . . . But wait... \mst was initially developed to easily use in math mode the document text font not in its italic variant, but as is, so, usually, upright. And upright \TeX{} fonts may also have italic correction data! And what I just said about the shift of the superscript with respect to the subscript apply equally well to such a font, if \TeX{} has been told to use it. Let's try Latin Modern Upright for letters in math: |$f_i^i$| now gives\footnote{we just use \texttt{\$\string\mathrm\{f\_i\^{}i\}\$}.} $\mathrm{f_i^i}$. We see the italic correction in action for the positioning of the superscript! Compare with |$\mathrm{\hbox{f}_i^i}$|: $\mathrm{\hbox{f}_i^i}$. Overlapping with |\rlap{$\mathrm{f_i^i}$}$\mathrm{\hbox{f}_i^i}$| gives \rlap{$\mathrm{f_i^i}$}$\mathrm{\hbox{f}_i^i}$ and shows that the upright $\mathrm{f}$ has an italic correction which was used to shift the superscript to the right (and it is now in a slightly lower position). Let's now do |$\mathrm{{f\/}_i^i}$|: this gives $\mathrm{{f\/}_i^i}$ and the subscript is shifted to the right, and is now on the same vertical axis as the superscript. There are also some slight vertical displacements, |\rlap{$\mathrm{f_i^i}$}$\mathrm{{f\/}_i^i}$| gives \rlap{$\mathrm{f_i^i}$}$\mathrm{{f\/}_i^i}$. People will tell me crazy, but if we decide for using upright fonts in math, wouldn't it be satisfying to have the subscript and superscript positioned on the same vertical axis? the letter has no slant, why should the indices display one? We end up in this strange situation that it is attractive to systematically incorporate the italic corrections after the upright Latin letters in math! But we don't want to do this inside the arguments to math alphabets as this would make impossible the formation of ligatures (the standard |$\mathrm{ff}$|, |$\mathit{ff}$|, |$\mathbf{ff}$|, |$\mathsf{ff}$| all give ligatures $\mathrm{ff}$, $\mathit{ff}$, $\mathbf{ff}$, and $\mathsf{ff}$ and we would like to preserve this behavior). \begin{framed}\kern-.75\baselineskip \begin{framed} Starting with version |v1.2b|, \mst adds the italic correction automatically after each letter of the Latin alphabet in math mode, \emph{except} when these letters are italic or slanted.\footnotemark\par These italic corrections are cancelled inside the arguments to the math alphabet commands others than \cs{mathnormal}, to allow the formation of ligatures as is expected in the standard default \TeX{} font set-up in math. \end{framed}\vskip-.75\baselineskip \end{framed} \footnotetext{the situation is rather ironical! by the way, the warnings in section \ref{sec:mathxx} related to \cs{MTnonletters\-obeymathxx} are less of an issue here, because the additional italic correction is added \emph{after} the original character.

They are especially useful when using an upright font in math mode.\footnote{The |mu| is a unit length used in math mode (`math unit', 1/18th of the `quad' value of the symbol font in the current style). Its value is relative to the current math style.} \begin{itemize} \item compare $\forall B$ with\MTforallskip{2mu} $\forall B$, typeset after |\MTforallskip{2mu}|, \item compare $\exists N$ with\MTexistsskip{2mu} $\exists N$, typeset after |\MTexistsskip{2mu}|, \item and finally compare $f'$ with\MTprimeskip{2mu} $f'$, typeset after |\MTprimeskip{2mu}|. \end{itemize} These three commands may be used throughout the document, or also in the preamble, in that case the declared math versions will record the then current values of the skips. \mst applies the following (small) default skips: |0.6667mu| for the skip after $\forall$, |1mu| for the skip after $\exists$, and |0.5mu| for the skip before the prime. The examples above become \MTforallskip{.6667mu}\MTexistsskip{1mu}\MTprimeskip{.5mu}$\forall B$, $\exists N$ and $f'$.\footnote{the derivative glyph from the |txfonts| math symbols adapts itself better to an upright letter, no skip seems to be needed then.} With the §italic§ option the defaults are set to zero. \MTversion{italic}\renewcommand\familydefault\sfdefault Indeed $\forall B$, $\exists N$ and $f'$ look fine without additional skips. If the document decides then to declare in the preamble a math version with an upright font it is thus recommended to use the commands in the preamble before the \cs{Mathastext}\oarg{version\_name} (or \cs{MTDeclareVersion}) command defining the version. They will be remembered when this math version is entered in the document. Or, the commands may be used directly in the document. Also, when the §subdued§ option has been used, the normal and bold math versions have by default zero length skips (no preamble setting will change that). Nevertheless it is possible to use also then the commands in the body of the document. \endgroup \subsection{Greek letters} The Computer Modern fonts are very light and thin in comparison to many text fonts, and as a result rarely mix well with them (particularly if the Latin letters in math mode are upright). The following options are provided by \mst: \begin{description} \item[no option:] nothing is done by the package, Greek letters are the default Computer Modern ones or have been set-up by other packages; for example by the |fourier| package with option `upright', which gives upright Greek letters. \item[§LGRgreek§:] this is for fonts which additionally to Latin letters also provide Greek letters in |LGR| encoding. Here is a list from a 2012 standard \TeX{} installation: the Computer Modern, Latin Modern, and the CM-LGC fonts; the Greek Font Society fonts (such as GFS Didot), the epigrafica and kerkis packages, the txfontsb package which extends the txfonts package with LGR-encoded Greek letters; the Droid fonts, the DejaVu fonts, the Comfortaa font, and the Open Sans font. The |LGR| encoded |CM/LM| fonts (in serif, sans-serif and typewriter family) give the nice Greek letters in upright shape from the |cbfonts| package. To get these letters in your \mst math mode, you can do the following: \begin{verbatim} % instructions to load the document fonts: \usepackage{nice_font} % and then the following: \renewcommand{\familydefault}{cmr} % or cmss or cmtt for sans resp. mono \usepackage[LGRgreek]{mathastext} \renewcommand{\familydefault}{\rmdefault} \Mathastext % this re-initializes mathastext with the nice_font, % without changing the LGR font cmr/cmss/cmtt used for Greek letters % in math mode. \begin{document} \end{verbatim} If you use the §italic§ option note that the italic Greek letters from the |cbfonts| are not the same glyphs as the default Greek letters from the |OML| encoded font |cmmi|. \item[§eulergreek§:] the Greek letters will be taken from the Euler font (the document does not have to load the eulervm package, \mst directly uses some file included in this package, as it provides a mechanism to scale by an arbitrary factor the Euler font.) The letters are upright. \item[§symbolgreek§:] the Greek letters will be taken from the (Adobe Postscript) Symbol font. A command is provided so that the user can scale the Symbol font to let it better fit with the text font. The letters are upright. \item[§selfGreek§:] this option concerns only the eleven Greek capitals from the |OT1|-encoding. It does nothing for the lowercase Greek letters. The encoding used in the document does not have to be |OT1|. \end{description} There is also §LGRgreeks§ which tells \mst to pick up in each math version the letters from the |LGR| encoded font used in that version, and §selfGreeks§ to tell \mst to do as for §selfGreek§ but separately in all math versions. The §subdued§ option interacts with the options for Greek letters in the following way: \begin{enumerate} \item in its presence, the §LGRgreek§ and §LGRgreeks§ options cease to have any effect in the normal and bold math versions, \item §selfGreek(s)§, §eulergreek§ and §symbolgreek§ act normally, they are not affected by the presence or absence of §subdued§. \end{enumerate} \subsubsection{Shape of Greek letters} Classic \TeX{} uses in math mode italic lowercase and upright uppercase Greek letters. French typography uses upright shape for both lowercase and uppercase. And the ISO standard is to use italic shape for both lowercase and uppercase. The Euler and Symbol fonts not being available in other than their default upright shape, this question of shapes for Greek letters raises issues only in the case of the options §LGRgreek§ and §selfGreek§. The options §frenchmath§, §itgreek§, §upgreek§, §itGreek§ and §upGreek§ modify the Greek letter shapes according to the following rules, listed from the lowest to the highest priority: \begin{description} \item[no option:] the lowercase Greek letters are in the same shape as Latin letters, and the uppercase in the same shape as applied to digits and operator names, \item[§frenchmath§:] both lowercase and uppercase are in the same shape as the digits and operator names (most of the time this means ``upright shape'', but it can be otherwise), \item[§itgreek,upgreek§:] both lowercase and uppercase are in the \cs{itdefault}, respectively the \cs{updefault} shape (at the time of loading the package or at the time of a subsequent call to \cs{Mathastext} or \cs{MathastextWillUse}), \item[§itGreek,upGreek§:] same as above, but only for the uppercase letters. \end{description} So, the default gives the classic \TeX{} behavior when option §italic§ was passed. Each call to \cs{Mathastext} (or \cs{MathastextWillUse}) macros (described in a later section) reinitializes the computation of the shapes. As mentioned already the package allows to define various ``math versions''. In the case of §eulergreek§ or §symbolgreek§ they apply to all these versions. In the case of the options §LGRgreeks§ or §selfGreeks§ (notice the additional ``s''), each math version is assumed to have its text font available in |LGR| (or |OT1| encoding) and also the shapes will be local to the math version. Finally version |1.15c| of \mst introduces new preamble-only commands to change the shapes, and even the font, used for Greek letters, in case of package options §LGRgreek§/§selfGreek§. They are §\MTitgreek§, §\MTupgreek§, §\MTitGreek§, §\MTupGreek§: these are used like the options and change only the shapes for the math versions which will be declared \emph{next} in the preamble; and §\MTgreekfont\{name\_of\_font\}§ will tell the \emph{next} math versions to use that font family. To use this command you need to know the (little) name of a suitable font family available in |LGR| encoding: for example |lmr|, |txr| (needs |txfontsb| package on your system), |DejaVuSerif-TLF| (needs |dejavu| package on your system), etc\dots \enlargethispage{\baselineskip} \subsection{Unicode engines} \mst has been made minimally unicode-aware and can be used with \XeTeX{} or \LuaLaTeX{}, but the user is strongly advised to look first at the |mathspec| package, which is a far more powerful package designed for unicode (only for \XeTeX{}), and to |unicode-math| (to use OpenType math fonts). Of course \mst is extremely far from being able to define a math font, as it applies basically only to a subset of the 32-127 ascii range, and in particular it does not know how to use a given Unicode font simultaneously for Latin and Greek letters. Again the user is strongly advised to look at |mathspec| and |unicode-math|. When using \mst with either \XeTeX{} or \LuaLaTeX{} it is recommended to use the |fontspec| package. Else, some of the encoding dependent things done by \mst like using the en-dash character to get a minus sign in math mode will not be put in place. Furthermore, it is \emph{necessary} to load |fontspec| with its |no-math| option, and this \emph{must} happen before loading \mst. \begin{framed} Use |fontspec| with its \emph{no-math} option, and load it \emph{prior} to \mst. \end{framed} \begin{framed} The |amsmath| package, if used, \emph{must} be loaded \emph{prior} to \mst. \end{framed} A little piece of the functionality of \mst is less fully realized under the \LuaLaTeX{} engine than it is with \XeTeX{}. This is a temporary situation as the needed feature of \LuaLaTeX{} has been implemented in its latest development release. I will update \mst when these binaries will have reached the distribution stage. I already mentioned in the section \ref{sec:ic} the fact that the italic corrections were not available for OpenType fonts under the \XeTeX{} engine and only partially available for the \LuaLaTeX{} engine, with the result that the spacings in math mode when using for the letters an upright text font will be less satisfying than with the standard |pdfetex| engine (the OpenType fonts not being usable with the latter engine, this is not a criterion of choice anyhow). To specify math versions using unicode fonts, use the |fontspec| \cs{setmainfont} command (with arbitrary optional features). This command can be issued before loading \mst, or after and then will be followed by a \cs{Mathastext} command with the name of the version in square brackets. It is possible to mix unicode fonts and classical \TeX{} fonts. But this is definitely \emph{not} recommended as \mst decides once and for all what is the font slot of things such as the text endash (used for the minus sign) and this is encoding dependent. So it is best to have either only unicode fonts, or only old-fashioned \TeX{} fonts in a fixed encoding (T1, or LY1 for example). The package was not extensively tested with unicode engines, but I include here two examples which compiled successfully with \XeTeX{} and \LuaLaTeX{}, the first one on a Linux machine, the second one on a Mac OS X machine.\footnote{running |latex| on the source of this document |mathastext.dtx| (in a temporary repertory) extracts the test files.} \begin{verbatim} \documentclass{article} \usepackage[hscale=0.8]{geometry} \usepackage{multicol} \usepackage[no-math]{fontspec} \usepackage{lmodern} \usepackage[subdued,italic]{mathastext} \setmainfont[Color=999999]{Verdana} \Mathastext[Verdana] \setmainfont[Color=0000FF]{Arial} \Mathastext[Arial] \setmainfont[Color=00FF00]{DejaVu Serif} \Mathastext[DejaVu] \MTDeclareVersion{times}{T1}{ptm}{m}{n} \MTlettershape{n} \setmainfont[Color=FF0000]{Andale Mono} \Mathastext[Andale] \begin{document} \newcommand\TEST[1]{\MTversion{#1}% \begin{multicols}{2} \hbox to\columnwidth{\hbox to\columnwidth{\hfil $abcdefghijklmnopqrstuvwxyz$\hfil}\kern-2.5em{#1}} \centerline{ $ABCDEFGHIJKLMNOPQRSTUVWXYZ$ } \centerline{ $0123456789$ } \centerline{ $!\,?\,*\,,\,.\,:\,;\,+\,-\,=\,(\,)\,[\,]\,/\,\#\,% \$\,\%\,\&\,<\,>\,|\,\{\,\}\,\backslash$ } \columnbreak \centerline{ abcdefghijklmnopqrstuvwxyz } \centerline{ ABCDEFGHIJKLMNOPQRSTUVWXYZ } \centerline{ 0123456789} \centerline{ !\,?\,*\,,\,.\,:\,;\,+\,-\,=\,(\,)\,[\,]\,/\,\#\,% \$\,\%\,\&\,<\,>\,|\,\{\,\}\,\char92 } \end{multicols}} \begin{multicols}{2} \centerline{\textbf{math mode}} \columnbreak \centerline{ \textbf{text} } \end{multicols} \TEST{DejaVu}\TEST{Verdana}\TEST{times}\TEST{Andale} \TEST{Arial}\TEST{bold}\TEST{normal} \end{document} \end{verbatim} And now the same thing with fonts available on Mac OS X: \begin{verbatim} \documentclass{article} \usepackage[hscale=0.8]{geometry} \usepackage{multicol} \usepackage[no-math]{fontspec} \usepackage{lmodern} \usepackage[subdued,italic]{mathastext} \setmainfont[Color=FF0000]{Hoefler Text} \Mathastext[Hoefler] \setmainfont[Color=336633]{American Typewriter}\Mathastext[Typewriter] \setmainfont[Color=0000FF]{Herculanum} \Mathastext[Herculanum] \setmainfont[Color=FF00FF]{Didot} \Mathastext[Didot] \setmainfont[Color=999999]{Comic Sans MS} \Mathastext[Comic] \begin{document} --- copy here the code from the previous example --- \TEST{Didot}\TEST{Comic}\TEST{normal}\TEST{Herculanum} \TEST{Hoefler}\TEST{Typewriter}\TEST{bold} \end{document} \end{verbatim} \subsection{Compatibility issues} Compatibility issues (or just questions of who decides last) are naturally to be expected with packages dealing with the math setting; the fix is simply to load \mst last. And one should always load |amsmath| before \mst (this is especially true when using Unicode engines but applies in general as well). In case of a `too many math alphabets' message try the |defaultalphabets| option or one of its |defaultnormal|, |defaulttt|, etc\dots sub-options. Starting with version |1.2|, \mst makes characters `mathematically active' to achieve certain effects: automatic insertion of the italic corrections when using an upright text font in math, extended scope of the math alphabet commands which now apply to non-letter symbols (and also to math operator names, but this is much easier to achieve). And the (already mathematically active) right quote is modified to have some extra space added before the derivative glyph ${}'$. Version |1.2b| does this in a careful manner with the hope to not create conflict with packages (typically, language definition files from the |babel| system) making characters `globally active' in the document.\footnote{it is better if these characters are not `catcode active' at the time of loading \mst, and fortunately |babel| does the activation of characters only at the \texttt{\string\begin\{document\}}.} All the action done by \mst is done anew at each math environment and has no effect elsewhere (even in hboxes included in a math mode group). Still, it is to be expected that all these `math active' characters will create incompatibilities (at least, surprises) with other packages. One such radical incompatibility arose with |amsmath|. To fix it, \mst now replaces an inner macro of |amsmath| (\cs{resetMathstrut@}) with its own version.\\ \null\hspace{1cm}\fbox{Always load |amsmath| before \mst.}\\ Actually this last commandment was already made necessary by the use of the text endash to represent the minus sign in math mode, and, especially for Unicode engines, some aspects of the \cs{DeclareMathOperator} macro from |amsmath|. \begin{framed}\kern-.75\baselineskip \begin{framed} \textbf{Important!} As is mentioned in the section \ref{sec:mathxx}, with the ``non letters obey math alphabets'' mechanism, characters such as |?|, or |[|, now represent \emph{two} `tokens' and this will utterly confuse \TeX{} if some precautions are not taken. Examples: |$0^+$| or |$x\mathrel?y$| \emph{must} be input now as |$0^{+}$| and, respectively, |$x\mathrel{?}y$|. This is why the package does \cs{MTnonletters\textbf{donot}\-obeymathxx} by default. \end{framed}\vskip-.75\baselineskip \end{framed} One thing to take note of is that this mechanism uses the \cs{everymath} and \cs{everydisplay}, so if it is needed to add to these \TeX{} `token lists' some additional things this should be done in a way preserving the former contents. Doing (after the |\begin{document}|) |\everymath={}| and |\everydisplay={}| (preemptively) annihilates all of the \mst (evil) doing with math active characters but it annihilates also everything else some other package might have put in there, so it is much better, in case the need arises to preemptively cancel the action of \mst, to use the package macros \cs{MTmathoperatorsdonotobeymathxx}, \cs{MTnonlettersdonotobeymathxx} (this is default), \cs{MTnoicinmath}, and \cs{MTnormalprime} (which cancels the redefinition done by \mst of the action of the right quote |'| in math mode). An exception is with the modifications to $\oldexists$ and $\oldforall$ which are done by the package in the preamble; the old definitions can be saved before to be reestablished after loading the package. Just using |\MTexistsskip{0mu}| and |\MTforallskip{0mu}| should be sufficient, except if it is important that the \cs{exists} and \cs{forall} control sequences always expand to only one token each. \section{Package options and commands} \subsection{Summary of main options} \begin{description} \item[{§italic, frenchmath§}:] italic letters in math, upright uppercase if §frenchmath§. \item[{§subdued§}:] acts in a subdued way. The \LaTeX{} normal and bold math versions are left (quasi) unchanged. With version |1.15e| of the package this statement applies also to the math alphabets \cs{mathbf}, \cs{mathit}, \cs{mathsf}, and \cs{mathtt} (and not only to \cs{mathnormal} and \cs{mathrm} as in previous versions.) \item[{§LGRgreek, eulergreek, symbolgreek§}:] the Greek letters will be taken, respectively from the text font itself (in |LGR| encoding), or from the Euler font, or from the Postscript Symbol font. \item[{§symbolmax§}:] all characters other than letters and digits, are taken from the Symbol font. This option also makes a number of further glyphs available, such as some basic mathematical arrows, and the sum and product signs. For documents with very simple needs in mathematical symbols, \mst with option §symbolmax§ may give in the end a PDF file quite smaller than the one one would get without the package. \item[{§defaultmathsizes§}:] \mst sets up bigger sizes for subscripts (it also copies code from the §moresize§ package to redefine \cs{Huge} and define \cs{HUGE}). Use this option to prevent it from doing so. \item[{§defaultalphabets§}:] by default, \mst redeclares the math alphabets \cs{mathrm}, \cs{mathit}, \cs{mathtt} etc\dots{} (but not \cs{mathcal} of course) to refer to the current document text fonts (at the time of loading the package and in each \mst math version). Use this option to prevent it from doing so (each alphabet also has its own disabling option). \end{description} \subsection{Miscellaneous} \begin{description} \item[the en-dash as minus sign:] very often the - character from the text font does not give a good minus sign. So by default, the package uses the en-dash sign \textendash{}. Use §noendash§ to deactivate it. Starting with version |1.12| of the package this `en-dash as minus' should work in all encodings, including Unicode (if |fontspec| has been loaded). \item[amsmath:] the behavior of the \cs{DeclareMathOperator} command of |amsmath| is slightly modified by \mst. This command initially allows crazy things like \cs{DeclareMathOperator}\cs{crazy}\{m.ch-in'tr/u:c\} and then the ., -, ', / and : will be typeset in the roman font. But the font number was hardcoded in the macro and furthermore the code of |amsmath| would cause an error with Unicode engine as soon as some Unicode code is assigned to the minus character.\footnote{To the experts: the $\sin$, $\cos$, \dots{} operator names are \emph{not} defined by |amsmath| with the help of the \cs{DeclareMathOperator} macro, hence are not the cause of an error in \XeTeX{}/\LuaLaTeX{}. What \mst does is to let to relax the \cs{newmcodes@} macro, so it is possible to save it before loading \mst and re-establish later, if really really this is what you want.} This specific issue will perhaps be fixed by some hypothetic future release of |amsmath|, or by other packages providing patches, but I decided for a preemptive strike. As a result the declaration above will not cause an error when \cs{crazy} is used with a Unicode engine, but there are now some spacings around the punctuation characters. To avoid this use (also with \LaTeX{}):\\ \centerline{\cs{DeclareMathOperator}\cs{crazy}\{m\{.\}ch\{-\}in\{'\}tr\{/\}u\{:\}c\}} Note though that the quote ' will be typeset as a derivative sign $'$. \item[hbar:] the definition of \cs{hbar} inherited from default \LaTeX{} will in our context make use of the §h§ of the current math font (so for us, it is also the text font, perhaps in italic shape), but the bar accross the §h§ will come from the original default math font for letters (usually |cmmi|), and furthermore its placement on the §h§ can be odd-looking. So we redefine \cs{hbar} to use only the text font (and this will be aware of the §italic§ option). Our construction does not always give an optimal result (and its scope is limited to the |OT1|, |LY1| and |T1| encodings), so an option §nohbar§ deactivates it. There is no \cs{hslash} provided by the package, though. The version |1.12| of the package when dealing with a Unicode font tries to get the \cs{hbar} directly as a glyph from the font. \item[dotless i and j:] by default the package redefines \cs{i} and \cs{j} to give the dotless i and j (if it exists at all), \emph{also in math mode,} in the text font. Will overwrite the default commands \cs{imath} and \cs{jmath}. In version |1.12| of the package this should work in all encodings, including Unicode (it is then assumed that |fontspec| has been loaded, and of course that the glyphs are indeed in the font). \item[asterisk:] previous versions of \mst did not do anything with the \cs{ast} control sequence but did pick the asterisk $*$ in the document text font, and this often was a rather silly thing as the text asterisk is generally in a raised position. Furthermore, the $*$ lost its status of a binary operator and was treated as an `ordinary' symbol. An option |noasterisk| turned this feature off. Starting with |1.2d|, the |noasterisk| option is deprecated and the new default is to do nothing. But when option §asterisk§ is received by the package, then both \cs{ast} and $*$ are simultaneously modified to use (as binary operators) the text asterisk, slightly lowered. The amount of lowering is decided by the argument to the macro \csb{MTlowerast}\marg{dimen} whose default value is |0.3\height|.\footnote{with the option \texttt{symbolmisc}, the asterisk is picked from the Symbol font, and the amount of lowering is non-customizable; however if a math alphabet command is used, the asterisk is then again from a text font and the lowering will be as specified by \cs{MTlowerast}.} The symbol will behave as expected in subscripts and subscripts of subscripts. But $*$ is now `mathematically active'\thinspace\footnote{in a hopefully safe way, for example {\ttfamily\$\string\label\{eq*1\}\$} is ok.} and |$R^*$| or |$R^\ast$| \emph{must} be input as |$R^{*}$| and |$R^{\ast}$|. Furthermore, they will obey the math alphabet commands. \item[\XeTeX{} and \LuaLaTeX{}:] for the en-dash and the dotless i and j, the package expects to detect either the EU1 encoding for XeTeX{} or the EU2 encoding for \LuaLaTeX{} (this will be true if |fontspec| was loaded), or one of |OT1|, |LY1| or |T1|, else it will renounce and not attempt to access the en-dash or the dotless i and j glyphs. With \LaTeX{} and Pdf\LaTeX{}, there is no such limitation and all 8bit-encodings (containing these glyphs) should be ok. \item[fontspec:] one more note to users of \XeTeX{}/\LuaLaTeX{} with |fontspec|: it has to be loaded {with the option} §no-math§, {and before} \mst. \item[vec accent:] The default \cs{vec} accent is not appropriate for upright letters, so \mst provides a \cs{fouriervec} which takes its glyph in a Fourier font, and an Ersatz \cs{pmvec} which is reasonably good looking on upright letters and works with the \cs{rightarrow} glyph. Contrarily to version |1.0|, the default \cs{vec} is not overwritten with \cs{fouriervec}. And contrarily to version |1.1|, one now needs to pass the option §fouriervec§ to have the math accent \cs{fouriervec} defined by the package. \item[math alphabets:] \begin{itemize} \item We define a new math alphabet command \cs{mathnormalbold} which gives direct access to the bold version of the \cs{mathnormal} alphabet (rather than using either the \cs{bm} command from the |bm| package or the \cs{boldsymbol} command from the |amsbsy| package). As it does not exist in the default \LaTeX{} math font set-up, this alphabet is \emph{not} subjected to the {subdued option} action. \item The other math alphabet changing commands defined by the package are \cs{MathEulerBold}, \cs{MathEuler} and \cs{MathPSymbol}. \item \cs{mathnormal}, \cs{mathrm}, \cs{mathbf}, \cs{mathit}, \cs{mathsf} and \cs{mathtt} are modified to make reference to the document text fonts (this can be disabled by suitable package options). \item version |1.2| of \mst has extended the scope of the math alphabets to apply to non-alphabetical characters and to operator names. This respects the automatic white spaces added by \TeX{} around math symbols. \end{itemize} \item[math accents:] an option §mathaccents§ is provided to pick up the accents in math mode from the text font, but the package knows only |T1|, |LY1| or |OT1|-compatible encodings. \end{description} Regarding the encoding-dependent glyphs: the en-dash, the dotless i and j, the math accents, the hbar, are encoding dependent and the relevant decisions are made once by \mst at the time it is loaded and are applied to all declared math versions. So you can use math versions with different encodings but, regarding these characters only those with the same encoding as the normal math version will display them correctly. \begin{framed} It is thus recommended that all declared mathastext math versions use the same font encoding. \end{framed} \subsection{Commands} \subsubsection{Preamble-only commands} These commands mainly facilitate the definition of math versions, in a \mst extended sense. It is thus not necessary to use them to activate the package basic functionalities, loading \mst is enough. \begin{itemize} \item §\Mathastext§ (or §\mathastext§): reinitializes \mst according to the current defaults of encoding, family, series and shape.\footnote{updates also the font and shapes for the Greek letters (§LGRgreek§ option), and the skips to be inserted after the symbols $\oldforall$ and $\oldexists$, see \emph{infra.}} \begin{itemize} \item It can also be preceded optionally by one or more of\footnote{these commands exist also with long names: \texttt{\char92Mathastextencoding}, etc\dots{} The same applies to the other commands mentioned in this section.} §\MTencoding§\marg{enc}, §\MTfamily§\marg{fam}, §\MTseries§\marg{ser}, §\MTshape§\marg{sh}, and, new with version |1.1|, §\MTlettershape§\marg{sh}. For example valid values are, respectively, \meta{T1}, \meta{phv}, \meta{m}, \meta{n}, and \meta{it}: this is the Helvetica font in T1-encoding, regular (medium) series, upright shape, and the letters will be in italic shape. Once used their effect applies to all succeeding calls to \cs{Mathastext}, and can only be undone by using them again. \item \textbf{math versions:} starting with version |1.12| \cs{Mathastext} accepts an optional argument \oarg{version\_name}, which will serve as a name to designate the corresponding math version (without optional argument \cs{Mathastext} redefines the default normal and bold versions.) This argument, being optional, must be enclosed within square brackets.\footnote{The allowed version names are as for the \LaTeX{} \cs{DeclareMathVersion} macro. Do not use ``normal'' or ``bold''; this is already taken care of by the initial loading of the package or a later command \cs{Mathastext} without any optional argument.} \end{itemize} \item §\MTWillUse§\oarg{ltsh}\marg{enc}\marg{fam}\marg{ser}\marg{sh}: tells \mst to use the font with the specified encoding, family, series, and shape for the letters and digits (and all other afflicted characters) in math mode. The optional argument \meta{ltsh} specifies a shape for the letters, for example \cs{itdefault}, or directly \meta{it} or \meta{sc}. \item §\MTDeclareVersion§\oarg{ltsh}\marg{name}\marg{enc}\marg{fam}\marg{ser}\marg{sh}: declares that the document will have access to the font with the specified characteristics, under the math version name \meta{name}. For example:\\ \hbox to\hsize{\hss§\MTDeclareVersion[sc]\{palatino\}\{T1\}\{ppl\}\{b\}\{sl\}§\hss} declares under the name |palatino| a version where mathematics will be typeset using the Palatino font in T1-encoding, bold, slanted, and the letters will in fact be in caps and small caps (and bold).\footnote{I do not especially recommend to use this in real life!} When the optional argument is absent, and \mst was loaded with the §italic§ option, then the default letter shape will be |it|,\footnote{more precisely, the shape is the latest value passed in one of the previously used package commands to specify the shape of letters, or the \cs{itdefault} of the time of loading the package.} else letters will have the same shape as used for digits and operator-names. \item §\MTboldvariant§\marg{var}: when used before §\Mathastext§, specifies which bold (|b|, |sb|, |bx|, \dots) to be used by \cs{mathbf} (and \cs{boldmath}). Default is the \cs{bfdefault} at the time of loading \mst. When used before the declaration of a version, decides the way \cs{mathbf} will act in this version. \item §\MTEulerScale§\marg{factor}: scales the Euler font by \meta{factor}. \item §\MTSymbolScale§\marg{factor}: scales the Symbol font by \meta{factor}. \item §\MTitgreek§, §\MTupgreek§, §\MTitGreek§, §\MTupGreek§: optional commands, active only in the case of the §LGRgreek§ option, to decide the shape of the Greek letters in the versions which will be declared next. \item §\MTgreekfont§\marg{fontfamily}: optional command with a mandatory argument which specifies the font for Greek letters in all \mst math versions declared afterwards via \cs{Mathastext} or \cs{MTDeclareVersion}. Only effective with §LGRgreek§ option. \end{itemize} \subsubsection{Commands usable everywhere}\label{sec:cmds} \begin{itemize} \item §\MTexistsskip§\marg{math glue}: specifies the amount of skip or more generally glue to put after each $\oldexists$ math symbol. Indeed, upright letters (or digits for that matter) often appear to be positioned a bit too close to the quantifier: $\oldexists\mathrm{B}$. The package default is to add a |1mu| skip (this default is set to zero in the case of §italic§): $\oldexists\mskip 1mu\mathrm{B}$. One can change the default with the following syntax: |\MTexistsskip{2mu plus 1mu minus 1mu}|, which if used in the preamble and followed with a \cs{Mathastext} command (or \cs{MTDeclareVersion}), will be recorded in the definition of this math version (and subsequent ones). One may also use the command at any time in the document. In the case of the option §subdued§, the skips are set to zero for the normal and bold math versions. In the case of the option §italic§, the default skip is set to zero. \item §\MTforallskip§\marg{math glue}: the default is to add a |.6667mu| math skip after each $\oldforall$ (except with the option §italic§ for which the default is set to zero). Compare $\oldforall\mskip.6667mu\mathrm{F}$ (has the skip) with $\oldforall\mathrm{F}$ (has no skip). Use this command in the preamble to set up the skip or glue to be used in the \emph{next to be declared} math versions. In the case of the option §subdued§, the skips are set to be zero by default in the normal and bold math versions. In the case of the option §italic§, the default skip is zero for all math versions. One may use the command also at any time in the document. \item §\MTprimeskip§\marg{math glue}: the default is to add a |0.5mu| skip before the derivative glyph, except for the §italic§ option, and except in the normal and bold math versions with option §subdued§. The same observations apply. \item §\MTlowerast§\marg{dimen}: a \cs{raisebox} command is used to lower the text asterisk to produce a reasonable math asterisk. The package uses the command with the argument |0.3\height|, this will have to be fine-tuned for each given text font but worked out ok with the fonts we tried. Not that the dimension argument will be used also in sub-scripts and sub-sub-scripts, so it is best not to use an absolute measure. \item §\MTmathoperatorsobeymathxx§, §\MTmathoperatorsdonotobeymathxx§, §\MTnonlettersobeymathxx§, §\MTnonlettersdonotobeymathxx§, §\MTexplicitbra\-cesobeymathxx§, §\MTexplicitbracesdonotobeymathxx§, §\MTeasynonlettersobeymathxx§, §\MTeasynonlettersdonotobeymathxx§: these commands without argument must be used \emph{outside} of math mode. \mst issues automatically §\MTmathoperatorsobeymathxx§, §\MTeasynonlettersobeymathxx§ and and §\MTnonletters\textbf{donot}obeymathxx§ at the time of \cs{usepackage\{math\-as\-text\}}. See the discussion in section \ref{sec:mathxx}. The `explicit braces' activation works only when \cs{MTnonletters\-obeymathxx} has already been used. \item §\MTicinmath§: this command tells \mst to add italic corrections after all letters in math mode. Its effect is cancelled inside math alphabets (except \cs{mathnormal}). The command is issued by default in the preamble when the shape of the letters used in math mode is neither italic nor slanted. It is reissued each time a math version is entered, under the same conditions (and except of course for the normal and bold subdued math versions). Its effect is local to the group or environment in which it has been issued. From inside math mode, it will only revert an earlier \cs{MTnoicinmath} from the same math group, and the math mode itself must have been entered with the italic corrections on. \item §\MTnoicinmath§: this command deactivates the package added italic corrections. It can be used inside as well as outside of math mode (or in the preamble of the document). Its effect remains local to the group or environment where it was issued. \item §\MTICinmath§, §\MTnoICinmath§: these commands set up the italic corrections only for the uppercase letters. Using §\MTICinmath§ de-activates the added italic corrections for uppercase letters in the arguments of \emph{all} the math alphabet commands. \item §\MTicalsoinmathxx§: this command de-activates the de-activation of the italic corrections inside the arguments to the math alphabet commands apart from \cs{mathnormal}. It can be issued in as well as outside of math mode.\footnote{it is provided for the \mst defined math alphabet \cs{mathnormalbold} which contrarily to \cs{mathnormal} is not treated apart from the other math alphabets.} To cancel its effect either enclose it in a group or environment or re-issue \cs{MTicinmath} after it. \end{itemize} \subsubsection{Body-only commands} \begin{itemize} \item §\MTversion§\oarg{nametext}\marg{namemath}:\footnote{\cs{MTversion} is also available as \cs{MTVersion}, \cs{Mathastextversion} and \cs{mathastextversion}.} in the absence of the optional argument changes simultaneously the text and the math fonts to be the fonts corresponding to the version \meta{namemath}. If there is an optional argument then the text fonts will use \meta{nametext} and the math mode will use \meta{namemath}. To change only the math fonts, one may use the \LaTeX{} command \cs{mathversion}. However this is not recommended as \mst does quite a lot of additional configuration when invoked with \cs{MTversion}. Each invocation of §\MTversion§ checks the chosen shape of letters in math mode and if it is not \emph{italic} or \emph{slanted} it activates the automatic insertion of italic corrections in math mode, for better positioning of subscripts. See the discussion in the section \ref{sec:ic}. With the §frenchmath§ option the package checks separately whether to insert the italic corrections after lowercase and/or uppercase letters. With the §subdued§ option, \cs{MTversion\{normal\}} and \cs{MTversion\{bold\}} do \cs{MTmathoperatorsdonotobeymathxx} (and \cs{MTnonlettersdonotobeymathxx}). \end{itemize} All further commands are for math mode only. \begin{itemize} \item §\hbar§: this is constructed (in a way compatible with the §italic§ option) from the §h§ letter and the \={ } accent from the \mst font. Note that \cs{mathrm}|{\hbar}| and \cs{mathbf}|{\hbar}| should work and that \cs{hbar} does scale in subscripts and exponents. Only for |T1| and |OT1| (or |LY1|) encodings. \item §\fouriervec§: this is a |\vec| accent taken from the Fourier font; the |fourier| package need not be loaded. Active only if option §fouriervec§. \item §\pmvec§: this provides a poor man \cs{vec} accent command, for upright letters. It uses the right arrow. Does not change size in subscripts and exponents. \item §\mathnormal§, §\mathrm§, §\mathbf§, §\mathit§, §\mathsf§, §\mathtt§: modifications of the original \cs{mathnormal}, \cs{mathrm}, \cs{mathbf}, \cs{mathit}, \cs{mathsf}, \cs{mathtt} to use the mathastextified font. The underlying internal \LaTeX{} structures related to the original commands are not overwritten, so the original commands can be saved under other names before |\usepackage{mathastext}|, to be used in case of necessity (this is what option |subdued| does.) \item §\mathnormalbold§: a bold version of \cs{mathnormal}. Differs from §\mathbf§ when the §italic§ option has been used, or when use has been made of §\MTlettershape§ to specify a shape for letters distinct from the one for digits and operator names, or similarly when the math version has been declared via §\MTDeclareVersion§ with its optional parameter for shape of letters. \item §\inodot§, §\jnodot§: the corresponding glyphs in the chosen font for math mode. By default, will overwrite |\imath| and |\jmath|. With version |1.12| by default §\i§ and §\j§ work also in math mode and give then §\inodot§, resp. §\jnodot§. This should work for all 8bit-encodings having these glyphs, and also in Unicode. \item §\MathEuler§, §\MathEulerBold§: math alphabets to access all the glyphs of the Euler font, if option §eulergreek§ (or §eulerdigits§) was passed to the package. \item §\MathPSymbol§: math alphabet to access the Symbol font. \item when one of the options §symbolgreek§, §eulergreek§, or §selfGreek§ is passed to the package the capital Greek letters which look like their Latin counterparts acquire names: \cs{Digamma}, \cs{Alpha}, \cs{Beta}, \cs{Epsilon}, \cs{Zeta}, \cs{Eta}, \cs{Iota}, \cs{Kappa}, \cs{Mu}, \cs{Nu}, \cs{Omicron}, \cs{Rho}, \cs{Tau}, \cs{Chi} (no \cs{Digamma} for Symbol). Also an \cs{omicron} control sequence is provided. \item |LGR| Greek and `var'-letters: only the \cs{varsigma} is available in this encoding, so using for example \cs{varphi} will load the previous default math font. It might thus be suitable when recompiling already written \LaTeX{} sources to add to the preamble \cs{let}\cs{varphi}$=$\cs{phi}, \cs{let}\cs{varepsilon}$=$\cs{epsilon}, etc\dots, in case only the `variant' form of the letter was used in the documents. \item \hypertarget{symbolmisc}{Miscelleneous mathematical symbols} from the postscript Symbol font are made available (or replaced) by option §symbolmisc§.\footnote{option §asterisk§ is also required to treat the $*$. Recall from section \ref{sec:mathxx} that the asterisk in math mode (also when using the control sequence \cs{ast}) appears then to \TeX{} to be a composite object.} \makeatletter\let\mst@doasterisk\mst@@doasterisk\makeatother They are \cs{prod}~$\prod$ \cs{sum}~$\sum$ \cs{implies}~$\implies$ \cs{impliedby}~$\impliedby$ \cs{iff}~$\iff$ \cs{shortiff}~$\shortiff$ \cs{to}~$\to$ \cs{longto}~$\longto$ \cs{mapsto}~$\mapsto$ \cs{longmapsto}~$\longmapsto$ \cs{aleph}~$\aleph$ \cs{inftypsy}~$\inftypsy$ \cs{emptyset}~$\emptyset$ \cs{surd}~$\surd$ \cs{nabla}~$\nabla$ \cs{angle}~$\angle$ \cs{forall}~$\forall$ \cs{exists}~$\exists$ \cs{neg}~$\neg$ \cs{clubsuit}~$\clubsuit$ \cs{diamondsuit}~$\diamondsuit$ \cs{heartsuit}~$\heartsuit$ \cs{spadesuit}~$\spadesuit$ \cs{smallint}~$\smallint$ \cs{wedge}~$\wedge$ \cs{vee}~$\vee$ \cs{cap}~$\cap$ \cs{cup}~$\cup$ \cs{bullet}~$\bullet$ \cs{div}~$\div$ \cs{otimes}~$\otimes$ \cs{oplus}~$\oplus$ \cs{pm}~$\pm$ \cs{ast}~$\ast$ \cs{times}~$\times$ \cs{proptopsy}~$\proptopsy$ \cs{mid}~$\mid$ \cs{leq}~$\leq$ \cs{geq}~$\geq$ \cs{approx}~$\approx$ \cs{supset}~$\supset$ \cs{subset}~$\subset$ \cs{supseteq}~$\supseteq$ \cs{subseteq}~$\subseteq$ \cs{in}~$\in$ \cs{sim}~$\sim$ \cs{cong}~$\cong$ \cs{perp}~$\perp$ \cs{equiv}~$\equiv$ \cs{notin}~$\notin$ \cs{langle}~$\langle$ \cs{rangle}~$\rangle$. And a \cs{DotTriangle}~$\DotTriangle$ is made available by option §symbolre§ (which overwrites \cs{Re} and \cs{Im}: $\Re,\Im$). The \cs{inftypsy} and \cs{proptopsy} have these names to leave up to the user the choice to replace (or no) the original (larger) \cs{infty} $\infty$ and \cs{propto} $\propto$. Regarding the \cs{prod} and \cs{sum} commands: they will use the Symbol glyphs $\prod\sum$ in inline math, and in display math the Computer Modern ones (or whatever is set up by other packages) : \[\prod\sum\] The package provides \cs{prodpsy} and \cs{sumpsy}: if one really wants in all situations the Symbol glyphs, one can do \cs{let}\cs{prod}\cs{prodpsy} and \cs{let}\cs{sum}\cs{sumpsy}. Also \cs{defaultprod} and \cs{defaultsum} will refer to the \cs{prod} and \cs{sum} before redefinition by the package: this is to allow constructs such as |$\displaystyle\defaultprod$| or |\[\textstyle\defaultprod\]|, because they would not work with the \cs{prod} and \cs{sum} as re-defined by the package. \end{itemize} \subsection{Complete list of options} \begin{itemize} \item §basic§: only mathastextify letters and digits. \item §subdued§: do not change the default fonts or the math alphabets in math mode for the normal and bold math versions, turn on the \mst-ification only after an explicit \cs{MTversion} (or \cs{mathastextversion}) command activating an additional math version as declared in the preamble. With option §subdued§ each \cs{MTversion\{normal\}} or \cs{MTversion\{bold\}} does \cs{MTmathoperatorsdonotobeymathxx} (and \cs{MTnonlettersdonotobeymathxx}). \item §italic§: the letters default to italic shape in math mode. \item §frenchmath§: italic lowercase Latin letters, but uppercase Latin letters in the same font as for digits and operator names. In general this means that they will be upright. In case of the §LGRgreek§ option, §frenchmath§ influences also the shape of the Greek letters. \item §endash§, §emdash§: use the text font en-dash (\textendash) or even the em-dash (\textemdash, but this seems crazy) for the minus sign rather than {}-{}. §endash§ option is default for the package. \item §asterisk§: use the text font (or the Symbol font) asterisk in math mode. \item §noendash§: the minus sign will be the - from the text font, not the en-dash \textendash. \item §nohbar§: prevents \mst from defining its own \cs{hbar}. \item §nolessnomore§: besides !\,?\,,\,.\,:\,;\,+\,\textendash\,=\,(\,)\,[\,]\,/\,\#\,\$\,\%\,\& \mst treats also \DeleteShortVerb{\|} $\mathord{<}\,\mathord{>}\,\mathord{|}$\, \{\,\} and $\backslash$.\MakeShortVerb{\|} Use this option to let it not do it. This is the default in case of |OT1|-encoding. \item further excluding options: §noexclam§ !\,?\ \ §nopunctuation§ ,\,.\,:\,;\ §noplus§, §nominus§, §noplusnominus§\ +\,\textendash{} §noequal§ =\ §noparenthesis§ (\,)\,[\,]\,/\ §nospecials§ \#\,\$\,\%\,\&\ and §nodigits§. \item §alldelims§: true by default, means that the characters excluded by §nolessnomore§ are treated. Use this option in case of a mono-width |OT1|-encoded font. \item §nosmalldelims§: this prevents \mst from trying to pick up in the text font the `small variants' of some math delimiters; it only affects what happens when a character such as a left parenthesis $($ or $[$ is used as a delimiter, and \TeX{} has chosen the smallest sized variant. This has no impact on what happens when they are not used as delimiters: then, and if not disabled by the corresponding options, these characters are always picked up from the text font. \item §symbolgreek§, §symboldigits§: to let Greek letters (digits) use the Symbol font. \item §symbolre§: replaces \cs{Re} and \cs{Im} by the Symbol glyphs $\Re, \Im$ and defines a \cs{DotTriangle} command ($\DotTriangle$). \item §symbolmisc§: takes quite a few glyphs, including logical arrows, product and sum signs from Symbol. They are listed \hyperlink{symbolmisc}{\emph{supra}}. Doing \cs{renewcommand\{\string\int\}\{\string\smallint\}} will maximize even more the use of the Symbol font. \item §symboldelimiters§: the characters apart from letters and digits will be taken from the Symbol font. \item §symbol§: combines §symbolgreek§, §symbolre§, and §symbolmisc§. \item §symbolmax§: combines §symbol§ and §symboldelimiters§. \item §eulergreek§, §eulerdigits§: to let Greek letters (digits) use the Euler font. \item §LGRgreek§: this is for a font which is also available in LGR-encoding. It is possible to change the font per math version, via the use of the §\MTgreekfont§ command in the preamble. \item §LGRgreeks§: each declared math version will be supposed to be with a font which is also available in LGR-encoding. \item §selfGreek§: this is for a font which is also available in |OT1|-encoding and contains the glyphs for the default eleven capital Greek letters. \item §selfGreeks§: each declared math version will be supposed to be with a font with the eleven capital Greek letters in its |OT1|-encoded version. \item §upgreek§, §itgreek§, §upGreek§, §itGreek§: options to tell to use \cs{itdefault} or \cs{updefault} for the lowercase and uppercase (or only the uppercase) Greek letters. Only operant in the case of the §LGRgreek(s)§ and §selfGreek(s)§ options. \item §mathaccents§: use the text font also for the math accents. As in vanilla \LaTeX{}, they are taken from the font for the digits and \cs{log}-like names. Obey the alphabet changing commands. Will work only for |T1|, |LY1|, or |OT1|-compatible encodings. \item §defaultbf§, §defaultit§, §defaultsf§, §defaulttt§: do not set up, respectively, the \cs{mathbf}, \cs{mathit}, \cs{mathsf}, and \cs{mathtt} commands to use the mathastext-ified font. This also prevents \mst to create internally \cs{Mathxx} alphabets (it never overwrites the original \cs{mathxx} things but let \cs{mathxx} point to \cs{Mathxx} instead), so one can use these options if one encounters a `too many math alphabets' \LaTeX{} error. \item §defaulnormal§, §defaultrm§: do not identify the default \cs{mathnormal} (resp. \cs{mathrm}) with the newly created \cs{Mathnormal} (resp. \cs{Mathrm}) commands which use the mathastextified fonts in each math version. \item §defaultalphabets§: all the §defaultxx§ options together, and additionally tells \mst not to create the \cs{mathnormalbold} alphabet either. \item §defaultimath§: do not overwrite \cs{imath} and \cs{jmath}, do not extend \cs{i} and \cs{j} to math mode use. \item §defaultmathsizes§: do not change the \LaTeX{} defaults for the sizes of exponents and subscripts. \item §fouriervec§: provides a \cs{fouriervec} command. The user can then add in the preamble \cs{let}\cs{vec}$=$\cs{fouriervec}. There is also always available a ``poor man'' vec accent \cs{pmvec} for upright letters. \end{itemize} Thanks to Kevin~\textsc{Klement}, Tariq~\textsc{Perwez} and Ricard~\textsc{Torres} for sending bug reports and feature requests when the first version of the package was issued. \begin{center} Numerous examples will be found there:\\ \url{http://jf.burnol.free.fr/mathastext.html}\\ \url{http://jf.burnol.free.fr/showcase.html} \end{center} \catcode`\§=12 \makeatletter \StopEventually{\check@checksum\end{document}} \makeatother \newgeometry{hmarginratio=3:2} \small \section{Implementation} \makeatletter \begingroup \topsep\MacrocodeTopsep \trivlist\parskip\z@\item[] \macro@font \leftskip\@totalleftmargin \advance\leftskip\MacroIndent \rightskip\z@ \parindent\z@ \parfillskip\@flushglue \global\@newlistfalse \global\@minipagefalse \ifcodeline@index \everypar{\global\advance\c@CodelineNo\@ne \llap{\theCodelineNo\ \hskip\@totalleftmargin}}% \fi \string\ProvidesPackage\string{\pkgname\string}\par \noindent\space [\pkgdate\space\pkgversion\space\pkgdescription]\par \nointerlineskip \global\@inlabelfalse \endtrivlist \endgroup \makeatother % The catcode hackery next is to avoid to have <*package> to be listed % in the commented source code... % (c) 2012/11/19 jf burnol ;-) \MakePercentIgnore % % \catcode`\<=0 \catcode`\>=11 \catcode`\*=11 \catcode`\/=11 % \let\relax % \def<*package>{\catcode`\<=12 \catcode`\>=12 \catcode`\*=12 \catcode`\/=12} % % %<*package> % \begin{macrocode} \NeedsTeXFormat{LaTeX2e} % \end{macrocode} % Testing for XeTeX and LuaLaTeX.
