Glib::KeyFile - Parser for .ini-like files  

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__

DESCRIPTION

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.  

METHODS

 

keyfile = Glib::KeyFile->new

 

boolean = $key_file->get_boolean ($group_name, $key)

•
$group_name (string)
•
$key (string)

Retrieves a boolean value from $key inside $group_name.

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

•
$group_name (string)
•
$key (string)
•
... (list) list of booleans
