Something along the lines of the following should work:
package Types;
use Moose::Util::TypeConstraints;
# note, need a type here, as otherwise coersions won't work if done as
a subtype of 'Str'
type "Types.pcr"
=> where { defined $_ and $_ =~ /^\d+$/ };
coerce "Types.pcr"
=> from "Str"
=> via { my $v = shift; $v =~ s/-//g; $v };
package UsageDetail;
use Moose;
# Note the 'coerce' flag and isa here
has pcr => (
is => "rw",
isa => "Types.pcr",
coerce => 1
);
package main;
my $dashful = UsageDetail->new( pcr => "9-8-7-6-5-4-3-2-1" );
my $dashless = UsageDetail->new( pcr => "123456789" );
print "Dashful: " . $dashful->pcr . "\n";
print "Dashless: " .$dashless->pcr . "\n"
-
The above gives:
Dashful: 987654321
Dashless: 123456789
