Its just a lickalized /i flag. So instead /i applying to your entire regex you apply it only to the parts it needs to be. Its a nice thing and I use it a lot.	[reply]

Well, I discovered that if I put the following in my code: `our $tom = "a big worthless poopyhead";` [download] and a guy named Tom who just so happens to be on the same development team as myself decides to look over said code in an attempt to understand what the sub that follows the declaration does, then he may become somewhat upset. I wonder what lesson tomorrow holds for me :-/	[reply] [d/l]

Has anyone else learned anything interesting today? No, but maybe you'll help me out on that score... You said, "Looking over my cow-orker's shoulder today" and that got me to wondering: Just how do you "ork" a cow? It isn't illegal, is it? Can you get a degree in cow-orking? (That would have to be a B.S. I guess.) How do you pay your cow-orker? Is he salaried? Hourly? Or do you pay by the cow? :-) -sauoq "My two cents aren't worth a dime.";	[reply]

You mean you've never orked? Been there, done that. I even have the T-shirt & cap :)) Examine what is said, not who speaks.

Well, I haven't learned anything today (yet), but the other day I learned that I really did know how to set up PGP to do a decrypt of a file. Now, if we can just get it to run properly in Windows from an unattached batch script.... :-) "Ex libris un peut de tout"	[reply]

is around thirty times faster Actually this dependent on the size of @patterns. When I benchmark them against each other i get more like a 100% speedup. Precalculating a hash of the patterns and then doing a hash lookup is infinitely faster.

Re: Re: You learn something every day by Jasper (Chaplain) on Aug 04, 2003 at 22:02 UTC
aha, but @patterns didn't contain just strings, it was full of all sort of regular expression trickery. Show me a hash lookup that'll work for that! Jasp Also, just in case anyone thought cow-orker really was a type, don't you read Dilbert?	[reply]
Re: Re: Re: You learn something every day by demerphq (Chancellor) on Aug 05, 2003 at 07:17 UTC
The use of /^(...)$/ lead me to believe it was simply strings. If @patterns is fully regexes then why not build the final regex only once with qr//? --- demerphq _{<Elian> And I do take a kind of perverse pleasure in having an OO assembly language...}	[reply] [d/l]

I learned that (?i:foo) does a case-insensitive non-remembering pattern match. Avoid /i Juerd # { site => 'juerd.nl', plp_site => 'plp.juerd.nl', do_not_use => 'spamtrap' }	[reply]
