 Posted: Tue Dec 22, 2015 12:04 am Post subject: Remove everything from last occurence |
 |
|
Trying my hand at some regex. I'm trying to take a string and remove everything after the last occurrence of and symbol.
I'm using | Code: | | regsub {\-.*} $text "" |
but it only works if there is only one occurrence of "-" but if text has more than one "-" it removing everything from the first occurrence back. Any help?
I have tried to use string and trim right but that doesn't help either
| Code: | | string range $text 0 [string last \- $text]-1 |

From the partyline in a bot of mine:
| Code: |
[09:18] <mynick> .set text abc-def-ghi-jkl-mno-pqr-stu-vwx-yz
[09:18] <botnick> [14:18:30] #jacky# set text abc-def-ghi-jkl-mno-pqr-stu-vwx-yz
[09:18] <botnick> Ok, set.
[09:18] <mynick> .tcl regsub -start [string last \- $text] {\-.*} $text ""
[09:18] <botnick> Tcl: abc-def-ghi-jkl-mno-pqr-stu-vwx
|
I hope this helps.

| Will this remove "-" in addition to everything after it? |

??
That's copy-n-paste, in my post above. It shows you exactly what it does.
Better yet, experiment with it in a script on your own bot. 
If it doesn't do what you wanted, then most likely it means that I didn't understand what you actually wanted.
Let us know how it goes.

Are you familiar with using the
.tcl
command in the partyline?
If not, perhaps what I put in my post is not something you instantly recognize, and you need to look that up and get familiar with it. It is very handy, at times.
