named

named(HashRef)

This attribute is read-only, accepts (HashRef) values, and is optional.

METHODS

The exists method takes a name or index and returns truthy if an associated value exists.

• exists example #1

    # given: synopsis
  
    $args->exists(0); # truthy
  

• exists example #2

    # given: synopsis
  
    $args->exists('flag'); # truthy
  

• exists example #3

    # given: synopsis
  
    $args->exists(2); # falsy
  

get

get(Str $key) : Any

The get method takes a name or index and returns the associated value.

• get example #1

    # given: synopsis
  
    $args->get(0); # --help
  

• get example #2

    $args->get('flag'); # --help

    package main;
  
    use Data::Object::Args;
  
    local @ARGV = qw(--help execute --format markdown);
  
    my $args = Data::Object::Args->new(
      named => { flag => 0, command => 1 }
    );
  
    $args->unnamed # ['--format', 'markdown']
  

• unnamed example #2

    package main;
  
    use Data::Object::Args;
  
    local @ARGV = qw(execute phase-1 --format markdown);
