Forums Scripts & Popups //x in regex

can any1 tell me what does //x in regex and if u can so //s too

Check the numerous of regex tutorials that floats around on the internet.

thank you, any1 else ??

//x makes regex ignore any whitespaces in the pattern. Example:
$regex(abc,/a b c/) -> 0
$regex(abc,/a b c/x) -> 1

//s makes the dot ( ".") match the LF character (char 10) too. By default, the dot matches every character except LF. Example:
$regex($lf,/./) -> 0
$regex($lf,/./s) -> 1

Seeing that most people vaguely recommend tutorials and stuff, I'd like to point out that it matters WHICH tutorial/manual you choose. mirc uses the PCRE library for regular expressions, so to learn all about mirc regex, one has to read the PCRE manual, not Perl/php/vbscript or whatever manual on regexes. For basic stuff, all these are ok, but your question is a good example of why the PCRE manual is necessary. Here it is

ok i will try to read him, and thx

hmm... but, why do i need to use //x if i can use:
$remove(...,$chr(32))

uh huh

It's there so you can make your pattern more readable. Why use $remove when you can smash it all together. I never use //x but then again I don't use $regex very often.

because regex isn't a mIRC invention - other languages don't have a $remove that functions just like mIRC's, and it makes a more readable regex pattern (hello oxymoronville)

hmm, there is a problem in that, i found out that it removes other chars except space

It also removes (ignores) #comments (preceded by "#"), therefore will remove #channel along with #comment.
