Ok, well firstly I don't know anything about $regex() but if the duration is really in bold you could so something like:
//echo -a $gettok("Blehblehbleh got posted 16d 5h 42m 12s ago by blehbleh..",2,2)

Hey dude, you could try to do this with a combination of Token Identifiers. You could try this until someone comes up with a $regex() pattern, but this seems to work for me. I've put it in a little alias to show you whats happening.
alias post {
var %string = Blehblehbleh got posted 16d 5h 42m 12s ago by blehbleh..
echo -a $gettok($gettok(%string,$+($findtok(%string,posted,1,32),-,$findtok(%string,ago,1,32)),32),$+(2,-,$calc($numtok($gettok(%string,$+($findtok(%string,posted,1,32),-,$findtok(%string,ago,1,32)),32),32) - 1)),32)
}
Obviously, %string holds the "Blehblehbleh got posted 16d 5h 42m 12s ago by blehbleh.." but this should give you an idea on how to manipulate it. Then just echoes it back basically. -Andy

var %blah = $regex($1-,/got posted (.*?) ago by/iS) This assumes $1- has the text line, strips color codes and ignores case (iS) and gives the time you wanted in $regml(1), until you do another $regex or $regsub. The var %blah is just used to get rid of the output of $regex, you can check if it actually matched or not, but then you better use if ($regex(..)) { ... } immediately if you want all numbers separately: var %blah = $regex($1-,/got posted (\d+d |)(\d+h |)(\d+m |)(\d+s |)ago by/iS) where $regml(1) has number of days or is $null if none, $regml(2) is hours, ... $regml(4) is seconds or $null if not present

Ah, that actually worked superb, Kelder. Another short question; How do i grab the fourth last word in a sentence? [ bapplander / today ] (what i wanna grab is marked in bold, and the phrase is at the end of a full sentence..

hey only 4 days to go! Not that its important here, as i see hes got a regex now but... I looked at your code, and have had to do the same thing myself (refrencing something twice, the gettok from posted to ago), I came up with a sneaky method of getting around that, although i think it could be done without this otherways, heres one way of reducing your code overhead, and processing time, for things like this. I incase the original $gettok(post to ago) inside a $iif( ,$v1), this then allows me to refrence it again as $v1, see the spaced out alignment of the two lines below.
echo -a $gettok( $gettok(%string,$+($findtok(%string,posted,1,32),-,$findtok(%string,ago,1,32)),32) ,$+(2,-,$calc($numtok($gettok(%string,$+($findtok(%string,posted,1,32),-,$findtok(%string,ago,1,32)),32),32) - 1)),32)
echo -a $gettok( $iif($gettok(%string,$+($findtok(%string,posted,1,32),-,$findtok(%string,ago,1,32)),32),$v1) ,$+(2,-,$calc($numtok($v1 ,32) - 1)),32)

Hehe very sneaky with $v1 to make ot shorter, I actually never thought of it. Yep 4 days, but it's almost midnight here in England, so theoretically it'll be 3 days, almost time to update profile..  -Andy

It's somewhat unclear what you want (and consider a word), so here's some guesses
get 4th last word, word being stuff between spaces: $gettok($1-,-4,32)
get something that is between "[ " and " / today ]": $regex($1-,/\[ (\w+?) \/ today \]/)) and the word is in $regml(1)

Blehblehbleh got posted 16d 5h 42m 12s ago by blehbleh
alias gettime {
if ($regex($strip($1-),/posted\s((?:\d+d\s)?(?:\d+h\s)?(?:\d+m\s)?(?:\d+s\s)?)\s?ago/)) { return $regml(1) }
}
Then just $gettime(input) well returned the parsed bit you wanted.

That's why I'd love to learn $regex() heh, it makes the code I did seem like I took the long route out, but I guess our codes did the same thing anyway, but yours is more smaller and don't take up a whole line, hehe..  -Andy

alias gettime {
if ($regex($strip($1-),/posted\s((?:\d+d\s)?(?:\d+h\s)?(?:\d+m\s)?(?:\d+s\s)?)\s?ago/)) { return $regml(1) }
}
Then just $gettime(input) well returned the parsed bit you wanted. [/quote] Well, that actually seemed to work quite good! However, i just discovered.. when the post is older than 24 hrs, the date is added to it aswell.. So then the correct string will be: Blehblehbleh got posted 16d 5h 42m 12s [11/05/2005] ago by blehblehIs it possible to modify the regex to fit to that? Get it to like skip or ignore [date] or something..? And also, i get "1 16d 5h 42m 12s" in the output, why do i get the first "1" character?

alias gettime {
if ($regex($1-,/posted ((?:\d+d )?(?:\d+h )?(?:\d+m )?(?:\d+s)?) ?(?:\[[\d/]+?\] )?ago/S)) {
return $regml(1)
}
}This should match the [date] stuff and ignore it. Used the //S modifier instead of $strip, rest is about the same...
