SYNOPSIS

package Term::CLI::Command {

   use Moo;

   with('Term::CLI::Role::ArgumentSet');

};

my $cmd = Term::CLI::Command->new( ... );

$cmd->add_argument( Term::CLI::Argument->new(...) );

DESCRIPTION

Role for Term::CLI::Command(3p) elements to represent a set of Term::CLI::Argument(3p) objects.

This role is consumed by Term::CLI::Command(3p).

ATTRIBUTES

This role defines two additional attributes:

arguments => ArrayRef

Reference to an array containing Term::CLI::Argument object instances that describe the parameters that the command takes, or undef.

Note that the elements of the array are copied over to an internal array, so modifications to the ArrayRef will not be seen.

ACCESSORS AND PREDICATES

has_arguments

Predicate function that returns whether or not any Term::CLI::Arguments have been added.

arguments

Return the list of Term::CLI::Argument object references that are owned by this object.

METHODS

set_arguments ( ARG, ... )

Reset the list of arguments to (ARG, ...). Each ARG should be a reference to a Term::CLI::Argument object.

add_argument ( ARG, ... )

Add ARG(s) to the argument set. Each ARG should be a reference to a Term::CLI::Argument object.

argument_names

Return the list of (sub-)command names (in the order they were specified).

SEE ALSO

Term::CLI(3p), Term::CLI::Command(3p).
