# MouseX::Getopt::Meta::Attribute::Trait(3pm)

## NAME MouseX::Getopt::Meta::Attribute::Trait - Optional meta attribute trait for custom option names

## SYNOPSIS

```
  package App;
  use Mouse;
  with 'MouseX::Getopt';
  has 'data' => (
      traits    => [ 'Getopt' ],
      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',
  );
```

## DESCRIPTION

This is a custom attribute metaclass trait 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.

- **cmd\_flag**

  Changes the commandline flag to be this value, instead of the default, which is the same as the attribute name.

- **cmd\_aliases**

  Adds more aliases for this commandline flag, useful for short options and such.

- **has\_cmd\_flag**

  - **has\_cmd\_aliases**
