In many Gnu Packages, much math expressions are not necessary.

Yep, it is very natural and a good example for many who want to use math expressions. Macros become important for fundamental expressions that occur frequently in a given field because they would have the advantage of simply calling them using popular names. > -- > Pat >

I think that a special mention would stil be good even if it is likely that math in a macro is not prevalent, as it is probably the main case with \ appearing naturally in text. -- Pat

I don't know if your use of math inside macros is likely to be prevalent enough to warrant special mention.
Re: @macro to accept hyphen
Have not seen a mathematical expression in the manual. Thusly I have provided
you with one. Works perfectly, no problem with it.
You have this sentence in the macro.
To get a single ‘\’ in the macro expansion, use ‘\\’
Although the information is there, it is very cryptic. If we include an
indented
example with a real math expression, users will be immediately drawn to it.

Your example works perfectly; what is the problem with it?
Re: @macro to accept hyphen
Did not know about the doubling \\. How is that? Could you include an example
of a macro with Mathematical expression? Have written an example for you.
@macro Mtk
@tex
In spherical coordinates, the Laplacian Operator is $\\nabla^2 \\phi(r)$.
$$\\nabla^2 \\phi(r) =
{1 \\over r^2} {\\partial \\over \\partial r}
\\bigg\\lbrack r^2 {\\partial \\phi \\over \\partial r}\\bigg\\rbrack$$
@end tex
@end macro

Re: @macro to accept hyphen
I have seen that mathematical expressions are not displayed when called within a macro. @macro Regu @tex \alpha @end tex @end macro @Regu @tex \beta @end tex > Sent: Saturday, November 07, 2020 at 10:38 PM > From: "Gavin Smith" > To: "Christopher Dimech" > Cc: "help-texinfo gnu" > Subject: Re: @macro to accept hyphen > > On Sat, Nov 07, 2020 at 08:23:50PM +0100, Christopher Dimech wrote: > > Would it be possible to allow macro names to use hyphens? > > > > @macro Regexp-EsnStruct > > Body > > @end macro > > It's a reasonable question, but it could cause horrendous problems > with TeX.

There is already special treatment of hyphens in various contexts (monospaced font, URL's, etc.) and trying to support hyphens in macro names could easily break in one of these contexts. In fact, digits are not even supported: only the 26 lower-case letters and 26 upper-case letters.
@macro to accept hyphen
Would it be possible to allow macro names to use hyphens? @macro Regexp-EsnStruct Body @end macro
