SYNOPSIS

9         my ($verbose, $source, $filenames) = ('', undef, []);
10
11         my $entries = [
12           { long_name => 'verbose',
13             short_name => 'v',
14             arg_type => 'none',
15             arg_value => \$verbose,
16             description => 'be verbose' },
17
18           { long_name => 'source',
19             short_name => 's',
20             arg_type => 'string',
21             arg_value => \$source,
22             description => 'set the source',
23             arg_description => 'source' },
24
25           [ 'filenames', 'f', 'filename-array', \$filenames ],
26         ];
27
28         my $context = Glib::OptionContext->new ('- urgsify your life');
29         $context->add_main_entries ($entries, 'C');
30         $context->parse ();
31
32         # $verbose, $source, and $filenames are now updated according to the
33         # command line options given

METHODS

40   optioncontext = Glib::OptionContext->new ($parameter_string)
41       •   $parameter_string (string)
42
43   optiongroup = Glib::OptionGroup->new (key => value, ...)
44       Creates a new option group from the given key-value pairs.  The valid
45       keys are name, description, help_description, and entries.  The first
46       three specify strings while the last one, entries, specifies an array
47       reference of option entries.  Example:
48
49         my $group = Glib::OptionGroup->new (
50                       name => 'urgs',
51                       description => 'Urgs Urgs Urgs',
52                       help_description => 'Help with Urgs',
53                       entries => \@entries);
54
55       An option entry is a hash reference like this:
56
57         { long_name => 'verbose',
58           short_name => 'v',
59           flags => [qw/reverse hidden in-main/],
60           arg_type => 'none',
61           arg_value => \$verbose,
62           description => 'verbose desc.',
63           arg_description => 'verbose arg desc.' }
64
65       Of those keys only long_name, arg_type, and arg_value are required.  So
66       this is a valid option entry too:
67
68         { long_name => 'package-names',
69           arg_type => 'string-array',
70           arg_value => \$package_names }
71
72       For convenience, option entries can also be specified as array
73       references containing long_name, short_name, arg_type, and arg_value:
74
75         [ 'filenames', 'f', 'filename-array', \$filenames ]
76
77       If you don't want an option to have a short name, specify undef for it:
78
79         [ 'filenames', undef, 'filename-array', \$filenames ]
80
81   $context->add_group ($group)
82       •   $group (Glib::OptionGroup)
83
84   $context->add_main_entries ($entries, $translation_domain)
85       •   $entries (scalar) reference to an array of option entries
86
87       •   $translation_domain (string)
88
89   boolean = $context->get_help_enabled
90   $context->set_help_enabled ($help_enabled)
91       •   $help_enabled (boolean)
92
93   boolean = $context->get_ignore_unknown_options
94   $context->set_ignore_unknown_options ($ignore_unknown)
95       •   $ignore_unknown (boolean)
96
97   optiongroup = $context->get_main_group
98   $context->set_main_group ($group)
99       •   $group (Glib::OptionGroup)
100
101   boolean = $context->parse
102       This method works directly on @ARGV.
103
104       May croak with a Glib::Error in $@ on failure.
105
106   $group->set_translate_func ($func, $data=undef)
107       •   $func (scalar)
108
109       •   $data (scalar)
110
111   $group->set_translation_domain ($domain)
112       •   $domain (string)
113
