bug#61936: Wish list: Tree-sitter support for GAP

[Tor Kringeland]

GAP is a computer algebra system (CAS) used in various areas of math.

There is already `gap-mode.el' [1] but it is not included in Emacs.

A tree-sitter module is available for GAP [2].

Is GAP free software?  That affects the moral/political question of
how much support for GAP we should include in Emacs (or any of our
software).

If GAP is free software then we would like to support it, unless
that causes a practical difficulty (it probably won't).

If it is nonfree, in principle we would rather not even mention its
existence.  But we can compromise in certain cases.  If it is already
quite well known, we can support it and say we support it, but keep in
mind that the goal of supporting is to encourage GAP users to use
Emacs while NOT encouraging Emacs users to use GAP.

If GAP is only somewhat well known, we can support it in the same way,
but we should not mention very much that we do support it.  We don't
want to publicize it!

GAP's license is GPL 2.0+.

That's good -- there is no copyright issue using it in Emacs.

Hei, Tor!

I see no reason not to support this in Emacs.  I do not know or use GAP
myself, but I'd be happy to review a patch adding it.  If you want to
make an attempt, I'd suggest to look at some of the simpler tree sitter
modes, such as java-ts-mode.el, and go from there.  The grammar file is
only ~350 lines, so I suspect support for it will only run in at less
than half the size of java-ts-mode.el :-)
