paulski has asked for the wisdom of the Perl Monks concerning the following question:

I found a better module on CPAN that does exactly what I need Parse::RandGen::Regexp.pm.

The problem I'm having now is how to get a regexp into this function. I wrote a stub progam to test.

#!/usr/bin/perl -w use strict; use Parse::RandGen::Regexp; my $regexp = "/^STOR\s[^\n]{100}/smi"; my $r = Parse::RandGen::Regexp->new($regexp); my $string = $r->pick(match=>1, captures=>{}); print("\$string: $string\n");
This throws the following error.
Unrecognized escape \s passed through at ./regexp2.pl line 6. %Error: Parse::RandGen::Regexp has an element that is not a Regexp re +ference (ref="")! at /usr/lib/perl5/site_perl/5.8.6/Parse/RandGen/Reg +exp.pm line 36 Parse::RandGen::Regexp::_newDerived('Parse::RandGen::Regexp=HASH(0 +x9dcdd88)', 'HASH(0x9e5f138)') called at /usr/lib/perl5/site_perl/5.8 +.6/Parse/RandGen/Condition.pm line 81 Parse::RandGen::Condition::new('Parse::RandGen::Regexp', '/^STORs[ +^\x{a}]{100}/smi') called at ./regexp2.pl line 7
Now I need the string in regexp format to pass to the function. I could just put the string in qr//s but in my real program I need to read the regexps from a list so they will come in scalar format.

i.e. How do I convert:

"/^STOR\s[^\n]{100}/smi";
to
qr/^STOR\s[^\n]{100}/smi
I'm not sure how to do this conversion.

Thanks,

Paul
