Highlighting the command line based on arbitrary rules

Highlighting the command line based on arbitrary rules

[Richard Hartmann]

Dear all,

this may be approaching the clinically and/or criminally insane, but
is it possible to highlight sections of the command based on arbitrary
rules?

My specific use case is to detect git commit message subjects which
are longer than the recommended 50 characters as such:

    git commit foo/bar -m 'foo/bar: More gizmos, less snafus, and a
general disregard of subject length'

I would want everything after 'general' would be highlighted and,
ideally, not run the highlighting code unless `git ` is at the
beginning of the command line.


Again, this may be a really stupid, or even impossible, idea but being
stuck at an airport without Internet connection but a git repo, a TODO
list, and a massive hangover make this look good.


Thanks,
Richard

Definitely.  Google for zsh-syntax-highlight for an extreme example.

Somebody probably even has a git plugin for that, but it's difficult
to search for, because of course the project is stored in github so
the addition of "git" to the search keywords is not helpful.

One caveat is that zsh-syntax-highlighting is currently known to tickle
an obscure memory management bug somewhere in the depths of ZLE.  We're
still hoping for somebody who can reproduce it to give us a valgrind or
similar debugging output.

Yeah, I've been noticing that a bunch of us old CVS-heads (myself
included) don't particularly bother with including a "subject" in our
commit messages.

Probably overkill in this case, but you might be interested in zpython
as well, see http://www.zsh.org/mla/workers/2013/msg00089.html .

Thanks.

If it's any consolation, it took me, a SVN-head, years to really _get_
git. Once you realize (a few times in a row, at deeper and deeper
levels) what "branches are cheap" implies, it's bliss.

Along similar line, you will learn to love the subject lines.
