backslashing

[TomSommer]

I have a variable that contains ":)"

now I want to do a regexp match for this, like so
set test ":)"
regexp -nocase $test $string

But then I get "couldn't compile regular expression pattern: parentheses () not balanced"

SO, then i thought I wanted to escape ")", but is there a function for this... or something easier? thx

You could write a function, but then you wouldn't be able to use any regexp special chars because they would all be escaped. That would make regexp totally useless... just use string match instead.

Change your code like this:

set test {:\)}
regexp -nocase $text $string
