G'day Neil,

Without seeing your module code, I can't say specifically what's wrong. I suspect your has functions have one or more of required, lazy or default incorrectly set up. See Moose - EXPORTED FUNCTIONS for details. The following works for me.

Moose module: pm_moose_default_params.pm

package pm_moose_default_params; use Moose; has colour => ( is => 'rw', isa => 'Str', required => 0, lazy => 1, default => 'red', ); has shape => ( is => 'rw', isa => 'Str', required => 0, lazy => 1, default => 'circle', ); no Moose; __PACKAGE__->meta->make_immutable;

Calling script: pm_moose_default_params.pl

#!/usr/bin/env perl use 5.010; use strict; use warnings; use Getopt::Long; use pm_moose_default_params; my $colour = ''; my $shape = ''; GetOptions('colour=s' => \$colour, 'shape=s' => \$shape); say "Option --colour = $colour"; say "Option --shape = $shape"; my %param; $param{colour} = $colour if $colour; $param{shape} = $shape if $shape; say "Param $_ = $param{$_}" for keys %param; my $object = pm_moose_default_params::->new(%param); say 'Moose colour = ', $object->colour; say 'Moose shape = ', $object->shape;

Some sample runs:

$ pm_moose_default_params.pl Option --colour = Option --shape = Moose colour = red Moose shape = circle $ pm_moose_default_params.pl --colour=blue Option --colour = blue Option --shape = Param colour = blue Moose colour = blue Moose shape = circle $ pm_moose_default_params.pl --shape=square Option --colour = Option --shape = square Param shape = square Moose colour = red Moose shape = square $ pm_moose_default_params.pl --colour=blue --shape=square Option --colour = blue Option --shape = square Param colour = blue Param shape = square Moose colour = blue Moose shape = square
