Add the repeating operator to the regex engine

One thing I have been frustrated about for a long time is the lack of the repeating operator (syntax being: {min,max} in the regex engine. It would be wonderful if you could add that to the regex engine in mIRC. For more info see http://www.regular-expressions.info/repeat.html

Khaled, your program is great. Keep up the good work!

It works fine, you just have to enclose it inside capturing brackets or put the regex in a variable first. This is because mIRC sees the , as an argument separator for the identifier.

Method 1: //echo -a $regex(abc,/(?:.{1,3})/)

Method 2: //var %re = /.{1,3}/ | echo -a $regex(abc,%re)

mirc's regex libraries already support the {N,M} quantifier!

Code:

//var %regex = /lo{1,5}l/ | echo -a $regex(looool,%regex)

i suspect you're having trouble with that comma, trying to plug it into the regex directly:

Code:

//echo -a $regex(looool,/lo{1,5}l/)

reason that doesn't work is pretty much the same effect as putting a comma directly into any other identifier. in the above, $regex() is passed 3 parameters, name = looool, string = /lo{1 and regex = 5}l/

there's a workaround, you can put the comma inside a group of parentheses:

Code:

//echo -a $regex(looool,/(?:lo{1,5}l)/)

if enclosed in (), the comma is no longer seen as a parameter separator :>

Hm, maybe. But it would be usefull if we didn't have to do all that work

It's really not possible not to, since mIRC wouldn't be able to tell whether you're passing a name, a string and expression, or just a string and expression.
