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
HIERARCHY¶

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)
