regsub prob

[jamesp0tter]

i've got 2 raw binds 2 get the chan topic, 332 & 333, but the topic often has chars like "[" and "]".. so it finishes up with "\]" and things like that..
so regsub to the rescue, but it keeps returming me this damn error:

[11:14] Tcl error [topic]: couldn't compile regular expression pattern: invalid escape \ sequence

what 2 do ?

i'm using -> regsub -all "\\" $tpc "" tpc <- anything wrong ? which should i use ?

tks in advance

There is no need to regsub.

The issue with the /, is usualy the cause of using Tcl lists and strings incorrectly.

The only thing I can sugest, is looking at the post in the FAQ forum, or posting the code, so we can point you in the right direction.

In lists, the use of proper list functions usually remove these pesty characthers... F.ex: if you are loading in the topic from the raw:

It comes in format
(the format is not 100% correct, but the general idea should be)
33x #chan :topic

You can use this to get the topic in correctly

set topic [split $topic ":"]
set topic [lindex $topic 1]

This should remove any pesky []...

If you want to use regexp for removing \ you need to use following escape sequence
"\\\\\\" or {\\} (not sure if i got the number \ correctly, but the amount is large...)
