package App; use Mouse; with 'MouseX::Getopt'; has 'data' => ( metaclass => 'MouseX::Getopt::Meta::Attribute', is => 'ro', isa => 'Str', default => 'file.dat', # tells MouseX::Getopt to use −−somedata as the # command line flag instead of the normal # autogenerated one (−−data) cmd_flag => 'somedata', # tells MouseX::Getopt to also allow −−moosedata, # −m, and −d as aliases for this same option on # the commandline. cmd_aliases => [qw/ moosedata m d /], # Or, you can use a plain scalar for a single alias: cmd_aliases => 'm', );
This is a custom attribute metaclass which can be used to specify a the specific command line flag to use instead of the default one which MouseX::Getopt will create for you.
This is certainly not the prettiest way to go about this, but for now it works for those who might need such a feature.
Custom Metaclass alias
This now takes advantage of the Moose 0.19 feature to support custom attribute metaclass aliases. This means you can also use this as the Getopt alias, like so:
has 'foo' => (metaclass => 'Getopt', cmd_flag => 'f');
Changes the commandline flag to be this value, instead of the default, which is the same as the attribute name.
Adds more aliases for this commandline flag, useful for short options and such.
