D-Bus is a daemon which provides a bus, i.e. many-to-many interprocess communication mechanism.

== Installation ==

Install <code>dbus</code> package:

<pre>
# apk add dbus
</pre>

== Running ==
There are two modes of D-Bus operation:

* '''system bus''': a single system-wide bus. Services connected to this bus are available to processes launched by any user; also it can be used to listen to system events like "new hardware was added" or "printer queue was changed";
* '''session bus''': one bus per user session for user-local services for general IPC needs.

=== System bus ===
System bus can be started with [[OpenRC]]:

<pre>
# rc-service dbus start
# rc-update add dbus default
</pre>

=== User bus ===
The most convenient way to launch session bus is to use <code>dbus-launch</code>

<pre>
$ export $(dbus-launch)
</pre>

{{Note|This weird syntax is used so variable containing D-Bus socket location ($DBUS_SESSION_BUS_ADDRESS) and its PID ($DBUS_SESSION_BUS_PID) get exported as environment variables for application}}

<code>dbus-launch</code> can be used to launch a program which would use this bus:

<pre>
$ dbus-launch my-bus-client
</pre>

To run a window manager, desktop environment or a shell with a bus session address available to it, use <code>dbus-run-session</code>:

<pre>
$ dbus-run-session sway
</pre>

This way, dbus session bus will terminate after you finish with your window manager or shell.
