ABSTRACT

Data-Object Command-line Options

SYNOPSIS

use Data::Object::Opts;

my $opts = Data::Object::Opts->new(
  args => ['--resource', 'users', '--help'],
  spec => ['resource|r=s', 'help|h'],
  named => { method => 'resource' } # optional
);

$opts->method; # $resource
$opts->get('resource'); # $resource

$opts->help; # $help
$opts->get('help'); # $help

DESCRIPTION

This package provides an object-oriented interface to the process' command-line options.

INTEGRATIONS

This package integrates behaviors from:

Data::Object::Role::Stashable

LIBRARIES

This package uses type constraints defined by:

Data::Object::Library

ATTRIBUTES

This package has the following attributes.

args

args(ArrayRef[Str])

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

spec

spec(ArrayRef[Str])

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

named

named(HashRef)

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

METHODS

This package implements the following methods.

exists

exists(Str $key) : Any

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

exists example
$opts->exists('method'); # exists $resource
$opts->exists('resource'); # exists $resource

get

get(Str $key) : Any

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

get example
$opts->get('method'); # $resource
$opts->get('resource'); # $resource

name

name(Str $key) : Any

The name method takes a name and returns the stash key if the the associated value exists.

name example
$opts->name('method'); # resource
$opts->name('resource'); # resource

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
my $options = $opts->parse;
my $options = $opts->parse(['bundle']);

set

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

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

set example
$opts->set('method', 'people'); # people
$opts->set('resource', 'people'); # people

stashed

stashed() : HashRef

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

stashed example
$opts->stashed; # {...}

warned

warned() : Num

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

warned example
my $warned = $opts->warned; # $count

warnings

warnings() : ArrayRef[ArrayRef[Str]]

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

warnings example
my $warnings = $opts->warnings;
my $warning = $warnings->[0][0];

die $warning;
