It was Wednesday, February 26, 2003 when Shawn took the soap box, saying:
: I have an issue with this snipppet:
: if ($file =~ /^${name}(.*)${suf}$/) {
:
: ...and that is, that the $name variable can end in a couple "+" chars,
: or some other special characters. This results in:
:
: Nested quantifiers in regex; marked by <-- HERE in m/^libsigc++ <-- HERE
: (.*).tar.bz2$/ at /03data/garnome-0.21.2/gnome/Report line 91.
You need to escape things like this. If you don't want special
characters like '+' to be notices as special, wrap that part of the
regex in '\Q' and '\E' sequences. This would make your regex look
something like this (when the needless curlies are removed):
/^\Q$name\E(.*)$suf$/
Enjoy!
