Regexp problem

[Mark Healey]

Here is the line that is giving me problems:

$Falbum =~ s/$edir\/.\/$Fartist\///;

The problem is that $Fartist sometimes has grouping characters "()[]"
which screws up the search.

How do I get it to treat these characters as if they were "\(\)\[\]"?

perldoc -f quotemeta

This doesn't help when I'm using some meta characters in my search
strings. I need something that only does it to the variables.

It was a hint that does help if you add some imagination. Following it
up by reading about \Q in "perldoc perlre" would also be useful.

Maybe I'm missing something but is there a problem with
$Fartist = quotemeta($Fartist);

Yes it does.

quotemeta only does it where you ask it to do it, so ask it to
do it "to the variables":

$edir = quotemeta $edir;
$Fartist = quotemeta $Fartist;
$Falbum =~ s#$edir/./$Fartist/##; # Look Ma! No backslashes!

or, lookup the \Q that the docs mention:

$Falbum =~ s#\Q$edir\E/./\Q$Fartist/##;

Is this a reference to the great Petomane?

Like most open source perldoc sucks. By the time you know enough to pick
the right terms to look for you don't need it.

$Falbum =~ s#\Q$edir\E/./\Q$Fartist/##;

That wasn't on my cheat sheet but I did eventually find it.

I know I don't need you.

Good to know there are some constants in life ;-) Like the infinite supply
of killfile candidates.
