Re: [PD] Chords parsing (with regexp)
I think it's best put as "PCRE *can* be slower", take care with non-greedy matches and captures in Perl type regex. For chords I guess you want the first good match anyway, although that's an assumption.

Re: [PD] Chords parsing (with regexp)
Hi, regex uses POSIX regex. pcre uses Perl-like regex, which are more powerful, but non-standard, I think. PCRE might be slower though. a 2007/4/26, IOhannes m zmoelnig <[EMAIL PROTECTED]>: > Alexandre Quessy wrote: > > Hi, > > > > I join an old draft patch using my draft [pcre] external.
