MooseX::Getopt::Meta::Attribute::NoGetopt - Optional meta attribute for ignoring parameters


version 0.76


  package App;
  use Moose;

  with 'MooseX::Getopt';

  has 'data' => (
      metaclass => 'NoGetopt',  # do not attempt to capture this param
      is        => 'ro',
      isa       => 'Str',
      default   => 'file.dat',


This is a custom attribute metaclass which can be used to specify that a specific attribute should not be processed by MooseX::Getopt. All you need to do is specify the NoGetopt metaclass.

  has 'foo' => (metaclass => 'MooseX::Getopt::Meta::Attribute::NoGetopt', ... );

Use 'traits' instead of 'metaclass'

You should rarely need to explicitly set the attribute metaclass. It is much preferred to simply provide a trait (a role applied to the attribute metaclass), which allows other code to further modify the attribute by applying additional roles.

Therefore, you should first try to do this:

  has 'foo' => (traits => ['NoGetopt', ...], ...);

Custom Metaclass alias

This now takes advantage of the Moose 0.19 feature to support custom attribute metaclass. This means you can also use this as the NoGetopt alias, like so:

  has 'foo' => (metaclass => 'NoGetopt', cmd_flag => 'f');
