> What is the syntax of regular expressions in scsh?
Well, there is plenty of documentation about regexps in various
widespread programs' documentation, like (e)grep, Emacs or Perl--you
certainly have one of these. The syntax is quite portable for the
"usual" operators, like ".", "", etc. The only difference worth
noting between Emacs' and scsh's regexps is that the "or" is written
"|" with scsh, not "\|" (Emacs notation) and the grouping operator is
"(" with scsh, and not "\(" (Emacs notation).
> Is there a scsh documentation project?
No, officially not (at least not to my knowledge). There was some
talk here about such a project a while back, but nothing happened.
The three sources of documentation about scsh are currently:
1. The scsh distribution, with all the files in the "doc" directory.
2. Shriram Krishnamurthi's notes about using the scsh web server,
3. The FAQ, available at:
(which contains a section called "Where can I find documentation
about scsh?" which might be of some interest to you).
And I also have an embryo of a scsh reference card in LaTeX (including
R4RS functions, etc.) lying somewhere on my hard-disk, but I lack the
time finishing it (and I will be in the army for the next four months
[*sigh*] so don't expect anything soon). Anyway, if someone has some
time to spend on it, I would be very happy to send him my embryo.
