=head1 NAME Glib::KeyFile - Parser for .ini-like files =cut =for position SYNOPSIS =head1 SYNOPSIS use Glib; $data .= $_ while (<DATA>); $f = Glib::KeyFile->new; $f->load_from_data($data); if ($f->has_group('Main') && $f->has_key('Main', 'someotherkey')) { $val = $f->get_integer('Main', 'someotherkey'); print $val . "\n"; } 0; __DATA__ # a comment [MainSection] somekey=somevalue someotherkey=42 someboolkey=true listkey=1;1;2;3;5;8;13;21 localekey=Good Morning localekey[it]=Buon giorno localekey[es]=Buenas dias localekey[fr]=Bonjour =for position DESCRIPTION =head1 DESCRIPTION B<Glib::KeyFile> lets you parse, edit or create files containing groups of key-value pairs, which we call key files for lack of a better name. Several freedesktop.org specifications use key files now, e.g the Desktop Entry Specification and the Icon Theme Specification. The syntax of key files is described in detail in the Desktop Entry Specification, here is a quick summary: Key files consists of groups of key-value pairs, interspersed with comments. =cut =for object Glib::KeyFile Parser for .ini-like files =cut =head1 METHODS =head2 keyfile = Glib::KeyFile-E<gt>B<new> =head2 boolean = $key_file->B<get_boolean> ($group_name, $key) =over =item * $group_name (string) =item * $key (string) =back Retrieves a boolean value from $key inside $group_name.
