ATTRIBUTES

This package has the following attributes:

args

args(ArrayRef[Str])

This attribute is read-only, accepts (ArrayRef[Str]) values, and is optional.

named

named(HashRef)

METHODS

This package implements the following methods:

exists

exists(Str $key) : Any

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

• exists example #1

    # given: synopsis
  
    $opts->exists('resource'); # truthy
  

• exists example #2

    # given: synopsis
  
    $opts->exists('method'); # truthy
  

• exists example #3

    # given: synopsis
  
    $opts->exists('resources'); # falsy
  

get

get(Str $key) : Any

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

• get example #1

    # given: synopsis
  
    $opts->get('resource'); # users
  

• get example #2

    # given: synopsis
  
    $opts->get('method'); # users
  

• get example #3

    # given: synopsis
  
    $opts->get('resources'); # undef
  

name

name(Str $key) : Any

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

• name example #1

    # given: synopsis
  
    $opts->name('resource'); # resource
  

• name example #2

    # given: synopsis
  
    $opts->name('method'); # resource
  

• name example #3

    # given: synopsis
  
    $opts->name('resources'); # undef
  

parse

parse(Maybe[ArrayRef] $config) : HashRef

The parse method optionally takes additional Getopt::Long parser configuration options and retuns the options found based on the object args and spec values.

• parse example #1

    # given: synopsis
  
    $opts->parse;
  

• parse example #2

    # given: synopsis
  
    $opts->parse(['bundling']);
  

set

set(Str $key, Maybe[Any] $value) : Any

The set method takes a name or index and sets the value provided if the associated argument exists.

• set example #1

    # given: synopsis
  
    $opts->set('method', 'people'); # people
  

• set example #2

    # given: synopsis
  
    $opts->set('resource', 'people'); # people
  

• set example #3

    # given: synopsis
  
    $opts->set('resources', 'people'); # undef
  
    # is not set
  

stashed

stashed() : HashRef

The stashed method returns the stashed data associated with the object.

• stashed example #1

    # given: synopsis
  
    $opts->stashed;
  

warned

warned() : Num

The warned method returns the number of warnings emitted during option parsing.

• warned example #1

    package main;
  
    use Data::Object::Opts;
  
    my $opts = Data::Object::Opts->new(
      args => ['-vh'],
      spec => ['verbose|v', 'help|h']
    );
  
    $opts->warned;
  

warnings

warnings() : ArrayRef[ArrayRef[Str]]

The warnings method returns the set of warnings emitted during option parsing.

• warnings example #1

    package main;
  
    use Data::Object::Opts;
  
    my $opts = Data::Object::Opts->new(
      args => ['-vh'],
      spec => ['verbose|v', 'help|h']
