(tye)Re: Fast lookup for prefixes in hash

I think that will probably be a whole lot slower than a (few) hash lookup(s) unless you optimize the regex like is dicussed in this thread: SAS log scanner

I'm well aware of that optimization necessity. I'm putting it in my book somewhere. _____________________________________________________ Jeff`[japhy]`Pinyan: Perl, regex, and perl hacker. `s++=END;++y(;-P)}y js++=;shajsj<++y(p-q)}?print:??;`	[reply]

Of course if you ever rewrite the regexp engine, you know what optimization will make the need for manually optimizing that regexp completely not needed... (Can I bribe you into trying? :-)	[reply]

You can stand by my side with a barf bag and/or the necessary drugs to program and debug the optimization. `;)` I'd like to try it, when I get the time. _____________________________________________________ Jeff`[japhy]`Pinyan: Perl, regex, and perl hacker. `s++=END;++y(;-P)}y js++=;shajsj<++y(p-q)}?print:??;`	[reply]
