MooseX::Getopt::Meta::Attribute - Optional meta attribute for custom option
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.
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 => ['Getopt'], cmd_flag => 'f');
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 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 and such.
