Just another regex engine.
I started with the Pike VM from re1 and built up something neat.
- No backtracking. (Yay Pike!)
- Arbitrary Look-Ahead / Look-Behind. If it's a valid regex, it can be used as Look-Around.
- Nesting Look-Around.
- Lots of Unicode support, except that I couldn't manage \q{} in sets, or case-munging.
- Brace-matching. (A property that Unicode kinda supports, but doesn't know it yet.)
- Better syntax than PCRE/Python/etc.
The DOCS.html file has more info.
