Summary: A client library for the D-Bus IPC system.

Description: 

D-Bus is a simple, message-based protocol for inter-process communication,
which allows applications to interact with other parts of the machine and
the user's session using remote procedure calls.

D-Bus is a essential part of the modern Linux desktop, where it replaces
earlier protocols such as CORBA and DCOP.

This library is an implementation of the D-Bus protocol in Haskell. It can
be used to add D-Bus support to Haskell applications, without the awkward
interfaces common to foreign bindings.

Example: connect to the session bus, and get a list of active names.

@ {-\# LANGUAGE OverloadedStrings \#-}

import Data.List (sort) import DBus import DBus.Client

main = do &#x20; client <- connectSession &#x20; // &#x20; \-- Request a
list of connected clients from the bus &#x20; reply <- call_ client
(methodCall \"\/org\/freedesktop\/DBus\" \"org.freedesktop.DBus\"
\"ListNames\") &#x20; &#x7b; methodCallDestination = Just
\"org.freedesktop.DBus\" &#x20; &#x7d; &#x20; // &#x20; \--
org.freedesktop.DBus.ListNames() returns a single value, which is &#x20;
\-- a list of names (here represented as [String]) &#x20; let Just names =
fromVariant (methodReturnBody reply !! 0) &#x20; // &#x20; \-- Print each
name on a line, sorted so reserved names are below &#x20; \-- temporary
names. &#x20; mapM_ putStrLn (sort names) @
