DESCRIPTION

33       Glib::KeyFile lets you parse, edit or create files containing groups of
34       key-value pairs, which we call key files for lack of a better name.
35       Several freedesktop.org specifications use key files now, e.g the
36       Desktop Entry Specification and the Icon Theme Specification.
37
38       The syntax of key files is described in detail in the Desktop Entry
39       Specification, here is a quick summary: Key files consists of groups of
40       key-value pairs, interspersed with comments.

METHODS

43   keyfile = Glib::KeyFile->new
44   boolean = $key_file->get_boolean ($group_name, $key)
45       •   $group_name (string)
46
47       •   $key (string)
48
49       Retrieves a boolean value from $key inside $group_name.
50
51       May croak with a Glib::Error in $@ on failure.
52
53   list = $key_file->get_boolean_list ($group_name, $key)
54       •   $group_name (string)
55
56       •   $key (string)
57
58       Retrieves a list of booleans from $key inside $group_name.
59
60       May croak with a Glib::Error in $@ on failure.
61
62   $key_file->set_boolean_list ($group_name, $key, ...)
63       •   $group_name (string)
64
65       •   $key (string)
66
67       •   ... (list) list of booleans
68
69       Sets a list of booleans in $key inside $group_name.  If $key cannot be
70       found then it is created.  If $group_name cannot be found then it is
71       created.
72
73   $key_file->set_boolean ($group_name, $key, $value)
74       •   $group_name (string)
75
76       •   $key (string)
77
78       •   $value (boolean)
79
80       Sets a boolean value to $key inside $group_name.  If $key is not found,
81       it is created.
82
83   string = $key_file->get_comment ($group_name=undef, $key=undef)
84       •   $group_name (string or undef)
85
86       •   $key (string or undef)
87
88       Retreives a comment above $key from $group_name.  If $key is undef then
89       $comment will be read from above $group_name.  If both $key and
90       $group_name are undef, then $comment will be read from above the first
91       group in the file.

103       $comment will be written above $group_name.  If both $key and
104       $group_name are undef, then $comment will be written above the first
105       group in the file.
