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.
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');
