- 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 |$\mathopen<A\mathclose>$| \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: |$\left<x\right>$| gives $\left<x\right>$ (but |$\left<b\right>$| gives $\left<b\right>$.) 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{<a,b>}| gives $\mathbf{<a,b>}$.
-|\mathbf{\left<a,b\right>}| gives $\mathbf{\left<a,b\right>}$.
-|\mathbf{\mathopen{<}a,b \mathclose{>}}| gives $\mathbf{\mathopen{<} a,b
- \mathclose{>}}$.

+
+\item §\MTsetmathskips§\marg{a-z|A-Z}\marg{muglue}\marg{muglue}:
+ \MakeShortVerb{\|}is used to specify extra skips (or rather mu glue) to be
+ inserted in math mode, before and after a letter. The rationale is that
+ standard text fonts used in math mode may sometimes cause glyph (near-)
+ collisions with math symbols, as \TeX{} has some implicit expectations on the
+ design of fonts for math letters. Random (silly) examples:
+ \centeredline{|\MTsetmathskips{x}{\medmuskip}{\thickmuskip}|} \centeredline
+ {|\MTsetmathskips{A}{.5mu}{2.3mu plus .5mu minus .5mu}|} and the effect:

+ rules.
+
+ Note that contrarily to the \csb{MTexistsskip}, \csb{MTforallskip}, and
+ \csb{MTprimeskip} commands described below, these extra skips (which may be
+ specified in the preamble) are not recorded in the definition of the math
+ version (as defined via \cs{Mathastext} with its optional argument or via

+ until modified or canceled, independently of the switches of math versions (of
+ course, \mst cancels the effect in the normal and bold math versions if
+ package option \blueit{subdued} was used).\DeleteShortVerb{\|}
+
+\item §\MTunsetmathskips§\marg{a-z|A-Z}: \MakeShortVerb{\|} cancels the effect
+ of a previous \cs{MTsetmathskips} for that letter (this is better than setting
+ the skips to |0mu|, which would still prevent formation of ligatures when the
+ letter is used inside a \cs{mathbf} for example). Example (using a version
+ with upright Latin
+ Modern): \centeredline
+ {|\MTsetmathskips{f}{8mu}{0mu}$gffg\MTunsetmathskips{f}ff\mathbf{ff}$|}

+\item §\MTmathstandardletters§: this command cancels the mechanism (used by the

+% The usual catcode regime for letters and digits is assumed and some characters
+% such as `, ", = are supposed to be of catcode other at the time of loading of
+% \mst. The source of \mst takes precautions for some other characters such as
+% the right quote ', which may thus be active with no harm at the time of
+% loading. By the way, I think \LaTeX2e should have provided to authors a
+% standard macro to be used at the beginning of a style file to make sure the
+% catcodes are standard. Shorthands created by Babel should be mostly no problem

+% |1.3| [2013/09/02]: user level command to specify extra spaces in math mode

+% skip to be inserted after; for example \cs{thickmuskip} or explicitely
+% |0.1mu| or |0.1mu plus 0.1mu minus 0.1mu|.
+%
+% For this, letters are made mathematically active. This is now the package

+% standard way.
+%
+% The command \cs{MTmathstandardletters} turns off math activation and its
