=head1 NAME
MooseX::App::Cmd::Command - Base class for MooseX::Getopt based App::Cmd::Commands
=head1 VERSION
version 0.34
=head1 SYNOPSIS
use Moose;
extends qw(MooseX::App::Cmd::Command);
# no need to set opt_spec
# see MooseX::Getopt for documentation on how to specify options
has option_field => (
isa => 'Str',
is => 'rw',
required => 1,
);
sub execute {
my ( $self, $opts, $args ) = @_;
print $self->option_field; # also available in $opts->{option_field}
}
=head1 DESCRIPTION
This is a replacement base class for L<App::Cmd::Command|App::Cmd::Command>
classes that includes
L<MooseX::Getopt|MooseX::Getopt> and the glue to combine the two.
=head1 METHODS
=head2 _process_args
Replaces L<App::Cmd::Command|App::Cmd::Command>'s argument processing in favor
of L<MooseX::Getopt|MooseX::Getopt> based processing.
If your class does the L<MooseX::ConfigFromFile|MooseX::ConfigFromFile> role
(or any of its consuming roles like
L<MooseX::SimpleConfig|MooseX::SimpleConfig>), this will provide an additional
C<--configfile> command line option for loading options from a configuration
file.
