Glib::OptionGroup − group of options for command line option parsing
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');

$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 ]

This method works directly on @ARGV.
May croak with a Glib::Error in $@ on failure.
