NAME¶
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__ # 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
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.
list = $key_file->get_boolean_list ($group_name, $key)¶
- $group_name (string)
- $key (string)
Retrieves a list of booleans from $key inside $group_name.

- $group_name (string)
- $key (string)
- ... (list) list of booleans
Sets a list of booleans in $key inside $group_name. If $key cannot be found then it is created. If $group_name cannot be found then it is created.
$key_file->set_boolean ($group_name, $key, $value)¶
