Hi all,
Prompted by some discussion and a bogus patch by me, Alex came up with
a very simple but effective fix for ticket #686. We've made a new
bugfix release for irregex, 0.9.1, so here's a patch to bring Chicken
up-to-date with upstream.
The fix is pretty simple; if you know the regex is a "searcher" (one
that starts with 'bos, ie the beginning of a string), don't loop in
the fold procedure because it can't possibly match anymore. This should
also improve performance for such regex matches that can be short-cut
like this.
Cheers,
Peter
