Re^5: Putting the stringified Regexp object into code

No, it's not necessary -- I said the qr was unnecessary, not qr//.

#!/usr/bin/perl
use strict;
use warnings;

my $re = qr(/);

$re =~ s!/!\\/!g;
my $code = "if (\$data =~ /$re/) { blah() }";

my $data = '/';
eval $code;

sub blah {
    print "hi"
}

I understand that you are auto-generating code; perhaps roboticus's response in Re^3: Putting the stringified Regexp object into code will make my point more clearly. There are times when string evaluated code is appropriate, but this would not be a time I'd select it.

#11929 First ask yourself `How would I do this without a computer?' Then have the computer do it the same way.

Ah, sorry. You're right of course. I have removed the "qr". Also see my response to roboticus. Point taken, but I do want to generate string code in this case. eval()-ing the string is just one, not the only thing, I want to do with the it.	[reply]
