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.

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

$key_file->set_boolean_list ($group_name, $key, ...)

$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)

$group_name (string)
$key (string)
$value (boolean)

Sets a boolean value to $key inside $group_name. If $key is not found, it is created.

string = $key_file->get_comment ($group_name=undef, $key=undef)

$group_name (string or undef)
$key (string or undef)

Retreives a comment above $key from $group_name. If $key is undef then $comment will be read from above $group_name. If both $key and $group_name are undef, then $comment will be read from above the first group in the file.
