Re^2: storing pre-compiled binary regexes

[Random_Walk]

Six years on and 5.10 is with us. Is it now possible to serialise and store the binary compiled version of the regex ?

Cheers,

OK, not sure if I am doing something wrong but from my testing Perl 5.10 can not do this either

This is perl, v5.10.0 built for MSWin32-x86-multi-thread
(with 3 registered patches, see perl -V for more detail)

Here is an attempt to store some compiled regex

#!/usr/bin/perl
#create the Storable file
use warnings;
use Storable;
use Data::Dumper;

my %sigs;
while (<DATA>){
    chomp;
   ($name,$value) = split(/\s+=\s+/,$_);
   next unless $value;
   $sigs{$name}= qr/$value/; 
}

store(\%sigs, 'z1.bin') or die "Can't store %a in z1.bin !\n";
print Dumper \%sigs;
exit;

And here I try to read it back again

#!/usr/bin/perl
#read the Storable file
#use strict;
use warnings;
use Storable;
use Data::Dumper;

my %sigs = %{retrieve('z1.bin')} or die "Unable to retrieve from z1.bi
+n:$!\n" ; 
print Dumper \%sigs;
exit;

__DATA__
1_Friday    = Friday
2_random    = [Rr]andom
3_catch any = .*

These are the results of the two dumps:

C:\Perl_5_10\play>..\bin\perl store.pl
$VAR1 = {
          '3_catch any' => qr/(?-xism:.*)/,
          '2_random' => qr/(?-xism:[Rr]andom)/,
          '1_Friday' => qr/(?-xism:Friday)/
        };

C:\Perl_5_10\play>..\bin\perl read.pl
$VAR1 = {
          '3_catch any' => qr/Regexp=SCALAR(0x1a6bca4)/,
          '2_random' => qr/Regexp=SCALAR(0x1a7c90c)/,
          '1_Friday' => qr/Regexp=SCALAR(0x1c47c7c)/
        };

if I try to use the read back regex they fail to match

Cheers,
R.
