Maybe Escape in Dynamic RegExpsby stefan k (Curate)
|on Apr 30, 2004 at 08:14 UTC||Need Help??|
stefan k has asked for the wisdom of the Perl Monks concerning the following question:
it has already been hard enough to find a good title for this question and even harder for me to find the solution to this problem (which -I am sure- must be very plain and simple, because I am looking for it so long(*))
I am building a regexp dynamically, say
(using a look behind just to make it a little more spicy) where $a and $b will always contain exactly one char, but that char might be special in regexps. For example $a can be "?" or "-" depending on the current situation.
The question is: is there any way (a module at CPAN which I have overlooked or an operator I didn't fully understand or ...) to dynamically escape those w/o me going through a list of special chars and checking them?
