Re: Can this be a 1 line or simpler regex?

in reply to Can this be a 1 line or simpler regex?

(fixed the code)

I suppose a single regex could be devised for this but it'd be suboptimal compared to what you already have. A short loop would also do this and again, I prefer your original.

$text =~ s/\\$r/\\\\$r/g for qw/t n r f/;

for(qw't n r f') {
    my $r = "\\$_";
    $text =~ s/$r/$r/g;
}

How's that supposed to work? As is it's a no-op. Makeshifts last the longest.	[reply]
