Hello perl-diddler,

If you look at the documentation for qr//, you’ll see that the /g modifier is not supported:

qr/STRING/msixpodualn
— perlop#Regexp-Quote-Like-Operators

Which makes sense: qr turns STRING into a regular expression, which may then be used in any number of m{...} and s{...}{...} constructs. The appropriate place to add a /g modifier is at the point of use:

use strict;
use warnings;
use P;      

my $re = qr{ (\w+) }x;
my $dat = "Just another cats meow";
my @matches = $dat =~ /$re/g;
P "#matches=%s, matches=%s", scalar(@matches), \@matches;
exit scalar(@matches);

Output:

12:53 >perl 1645_SoPW.pl
#matches=4, matches=["Just", "another", "cats", "meow"]

12:54 >

Update:

P.S. - I also just noticed that in addition to stripping out the 'g' option, the 'x' option doesn't seem to work in the regex's parens, i.e. - (?x).

I don’t understand what you’re saying here. Can you give some example code?

Hope that helps,
