First of all, the things that are promised for 5.10. :) These include:
- defined or: // and //=
- speed improvements in regexes as promised (and implemented) by demerphq
- recursive regexes! (ditto)
Aside from that, I'd like to see support for matching regexes across boundaries for partially loaded buffers. That would ease processing files in blocks of a few k each, instead of having to load the entire file into a string.
As an example: say you're looking for a word "SELECT" and the buffer contains:
my $sth = $dbh->prepare('SEL
It's possible that it would have matched "SELECT" if the buffer wasn't cut off.
I'd like regexes to be able to catch that. Automatically.
I don't really care how it's done, but I personally favor a system that takes some action (die, set a variable, call a callback sub) when the lookahead "touches" the back end of the buffer. (I call that the "electric fence" approach: touch it and you're dead.)
