Forums Scripts & Popups regsub to remove NON numerics ????

ok i suck at regsub, and i could always just do a dirty big $remove but i thought someone might know a simple $regsub for it that wont look so ugly, like regex any non number and replace with nothing?

I want to remove anything besides 0123456789 from a var

example
var %value = 489.290djdue93jd93hjs923" $+ , $+ 59sj39e3333" ssss999 $crlf blah 1
(ie: anything at all)

Result i want 4892909393923593933339991

Thanks in advance guys. (and girls?)

Using $regsub



Using $regsubex



[0-9] will match any digit, by adding the ^ it means to match anything except a digit. The /g modifier is used to find all matches in the string.

Thanks man, damn simple when u know how, i spent 15 to 20 mins on it and still couldnt do it LOL, damn my old brain! its run out of room for anything new like regex.

Erm, sorry. If you use the $regsubex method, it can be simply:

alias numonly return $regsubex($1-,/[^0-9]/Sg,)

I just realized it should have been that way, however it will work either way. Though, in this one I added the S modifier to strip text before matching (in the off chance that your var contains colors).

If you wish to learn regex, hixxy has a pretty good tutorial: here to get you started if you haven't already looked through it.

Not to nitpick, but [0-9] is \d and [^0-9] is \D .

And in this specific case, the S switch isn't necessary since all control codes would be considered "not digits" anyway.

To nitpick even further I'd use \D+ to remove multiple consecutive non-digits in one sweep, rather than removing them one by one.

Not necessarily true. schaefer31 clarified:

Eg $regsubex(1test2,/\D+/g,) = "12"
but $regsubex(1test2,/\D+/gS,) = "2"
So it really depends on what DaveC wants: if he wants to keep only "visible" (ie not part of a color sequence) digits, /S should be used.

Thanks everyone for the adjustments, also thanks for explaining the /S, however $regsubex($1-,/\D+/g,) is what i require for my need, the data im parsing isnt irc messages, so i doubt there would be control codes there anyway, but just as i think i said, any non numerics need dumping. (I should have thought to include a ctrl-k12,3 with output retaining 123 in it but i didnt really think about it)
