Manual Reference Pages - MOOSEX::GETOPT::META::ATTRIBUTE (3)
MooseX::Getopt::Meta::Attribute - Optional meta attribute for custom option names
has data => (
metaclass => Getopt,
is => ro,
isa => Str,
default => file.dat,
# tells MooseX::Getopt to use --somedata as the
# command line flag instead of the normal
# autogenerated one (--data)
cmd_flag => somedata,
# tells MooseX::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 MooseX::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.
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
Therefore, you should first try to do this:
has foo => (traits => [Getopt], cmd_flag => f);
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 <B>GetoptB> alias, like so:
has foo => (metaclass => Getopt, cmd_flag => f);
Changes the command-line flag to be this value, instead of the default,
which is the same as the attribute name.
Adds more aliases for this command-line flag, useful for short options
