Forums Scripts & Popups Using regexps in script

Hello, i have two small regexps i would like to implement in a script.. It checks $2 for valid chars, and if not returtn..



The regexps i want to use is {[regexp -all {\(} $2]!=[regexp -all {\)} $2]} and {[regexp {[^a-zA-Z0-9\(\)_.\-]} $2]} .
How do i use them?

Look at /help $regex for info on regular expressions. The syntax you are using looks like TCL. mIRC uses the PERL (proper) syntax for regex. For more info on the syntax, go here: http://www.regular-expressions.info

Looking at your example, it seems like you want to ensure that there are equal numbers of ( and ) characters. In mIRC you can do that easily like this:

if ($count($2,$chr(40)) != $count($2,$chr(41))) return

To check if there are any invalid characters, you can use this regex:

if ($regex($2,[^\w().-])) return

Just a note, certain characters don't need to be escaped when they are within [] brackets.

Thanx dude, I'll have a look at it.

BTW; how can i check that ( always comes first before ) ?
like (hello) and not )hello( ?

//tokenize 32 (hello) | if ($regex($1,/^\50[\w.-]+\51$/)) echo -a match
//tokenize 32 )hello( | if ($regex($1,/^\50[\w.-]+\51$/)) echo -a match

The regex matches: (a-zA-Z0-9_-.) where the part in between brackets can be 1 or more consequent chars that match that criteria.

hm.. how do i use that in my script, though?
to check that ( always comes before ) in $2, and that it have to be atleast two chars within ( and )..

if ($regex($2,/^\50(?:[\w.-]{2,})\51$/)) echo -a match

Btw, you should learn basic mIRC scripting first before trying regex, as you could have solved this fairly easy with regular scripting.
