NAME

Glib::OptionGroup - group of options for command line option parsing  

SYNOPSIS

  my ($verbose, $source, $filenames) = ('', undef, []);

  my $entries = [
    { long_name => 'verbose',
      short_name => 'v',
      arg_type => 'none',
      arg_value => \$verbose,
      description => 'be verbose' },

    { long_name => 'source',
      short_name => 's',
      arg_type => 'string',
      arg_value => \$source,
      description => 'set the source',
      arg_description => 'source' },

    [ 'filenames', 'f', 'filename-array', \$filenames ],
  ];

  my $context = Glib::OptionContext->new ('- urgsify your life');
  $context->add_main_entries ($entries, 'C');
  $context->parse ();

  # $verbose, $source, and $filenames are now updated according to the
  # command line options given

METHODS

 

optioncontext = Glib::OptionContext->new ($parameter_string)

$parameter_string (string)
 

optiongroup = Glib::OptionGroup->new (key => value, ...)

Creates a new option group from the given key-value pairs. The valid keys are name, description, help_description, and entries. The first three specify strings while the last one, entries, specifies an array reference of option entries. Example:

  my $group = Glib::OptionGroup->new (
                name => 'urgs',
                description => 'Urgs Urgs Urgs',
                help_description => 'Help with Urgs',
                entries => \@entries);

An option entry is a hash reference like this:

  { long_name => 'verbose',
    short_name => 'v',
    flags => [qw/reverse hidden in-main/],
    arg_type => 'none',
    arg_value => \$verbose,
    description => 'verbose desc.',
    arg_description => 'verbose arg desc.' }

Of those keys only long_name, arg_type, and arg_value are required. So this is a valid option entry too:

  { long_name => 'package-names',
    arg_type => 'string-array',
    arg_value => \$package_names }

For convenience, option entries can also be specified as array references containing long_name, short_name, arg_type, and arg_value:

  [ 'filenames', 'f', 'filename-array', \$filenames ]

If you don't want an option to have a short name, specify undef for it:

  [ 'filenames', undef, 'filename-array', \$filenames ]

 

$context->add_group ($group)

$group (Glib::OptionGroup)
 

$context->add_main_entries ($entries, $translation_domain)

$entries (scalar) reference to an array of option entries
$translation_domain (string)
 

boolean = $context->get_help_enabled

 

$context->set_help_enabled ($help_enabled)

$help_enabled (boolean)
 

boolean = $context->get_ignore_unknown_options

 

$context->set_ignore_unknown_options ($ignore_unknown)

$ignore_unknown (boolean)
 

optiongroup = $context->get_main_group

 

$context->set_main_group ($group)

$group (Glib::OptionGroup)
 

boolean = $context->parse

This method works directly on @ARGV.

May croak with a Glib::Error in $@ on failure.  

$group->set_translate_func ($func, $data=undef)

$func (scalar)
$data (scalar)
 

$group->set_translation_domain ($domain)

$domain (string)
