интерфейс D-Bus локализованной системы (The D-Bus interface of systemd-localed)
Имя (Name)
org.freedesktop.locale1 - The D-Bus interface of systemd-localed
Вступление (Introduction)
systemd-localed.service(8) is a system service that can be used
to control the system locale and keyboard mapping from user
programs. This page describes the D-Bus interface.
API D-bus (системы межпроцессного взаимодействия) (The d-bus API)
The service exposes the following interfaces on the bus:
node /org/freedesktop/locale1 {
interface org.freedesktop.locale1 {
methods:
SetLocale(in as locale,
in b interactive);
SetVConsoleKeyboard(in s keymap,
in s keymap_toggle,
in b convert,
in b interactive);
SetX11Keyboard(in s layout,
in s model,
in s variant,
in s options,
in b convert,
in b interactive);
properties:
readonly as Locale = ['...', ...];
readonly s X11Layout = '...';
readonly s X11Model = '...';
readonly s X11Variant = '...';
readonly s X11Options = '...';
readonly s VConsoleKeymap = '...';
readonly s VConsoleKeymapToggle = '...';
};
interface org.freedesktop.DBus.Peer { ... };
interface org.freedesktop.DBus.Introspectable { ... };
interface org.freedesktop.DBus.Properties { ... };
};
Methods
If you set a new system locale all old system locale settings
will be dropped and the new settings will be saved to disk. The
locale will also be passed to the system manager, and
subsequently started daemons will inherit the new system locale.
Note that already running daemons will not learn about the new
value.
The SetVConsoleKeyboard() method may be used to set the key
mapping for the virtual console. Similarly, SetX11Keyboard() may
be used to set the default key mapping of any X11 servers.
Note that SetVConsoleKeyboard() instantly applies the new key
mapping to the console, while SetX11Keyboard() simply sets a
default that may be used by later sessions.
The boolean argument convert may be set to optionally convert the
console keyboard configuration to X11 keyboard mappings and vice
versa. If true and SetVConsoleKeyboard() is used, the nearest X11
keyboard setting for the chosen console setting is set. If true
and SetX11Keyboard() is used, the nearest console keyboard
setting for the chosen X11 setting is set. Hence, it is usually
sufficient to call only one of the two functions.
For graphical UIs that need to set the system keyboard mapping
simply invoke SetX11Keyboard(), set convert=true and ignore
SetVConsoleKeyboard().
Use the empty string for the keymap parameters you wish not to
set.
The interactive boolean parameters can be used to control whether
polkit
Signals
Whenever the system locale or keymap is changed via the daemon,
PropertyChanged signals are sent out to which clients can
subscribe.
Properties
The system locale is shown in the Locale property. It is an array
containing environment-variable-assignment-like strings. The
following strings are known: LANG=, LC_CTYPE=, LC_NUMERIC=,
LC_TIME=, LC_COLLATE=, LC_MONETARY=, LC_MESSAGES=, LC_PAPER=,
LC_NAME=, LC_ADDRESS=, LC_TELEPHONE=, LC_MEASUREMENT=,
LC_IDENTIFICATION=.
The X11Layout, X11Model, X11Variant, and X11Options properties
show values configurable with SetX11Keyboard() described above
(or SetVConsoleKeyboard() with convert=true). The VConsoleKeymap
and VConsoleKeymapToggle properties show values configurable with
SetVConsoleKeyboard() (or SetX11Keyboard() with convert=true).
Security
Changing the system locale or keymap using this interface is
authenticated via polkit. The polkit action for SetLocale() is
org.freedesktop.locale1.set-locale. The polkit action for
SetX11Keyboard() and SetVConsoleKeyboard() is
org.freedesktop.locale1.set-keyboard.
Примеры (Examples)
Example 1. Introspect org.freedesktop.locale1 on the bus
$ gdbus introspect --system \
--dest org.freedesktop.locale1 \
--object-path /org/freedesktop/locale1
