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 client <- connectSession -- Request a list of
connected clients from the bus reply <- call_ client (methodCall
"/org/freedesktop/DBus" "org.freedesktop.DBus" "ListNames") {
methodCallDestination = Just "org.freedesktop.DBus" }
-- org.freedesktop.DBus.ListNames() returns a single value, which is --
a list of names (here represented as [String]) let Just names =
fromVariant (methodReturnBody reply !! 0) -- Print each name on a
line, sorted so reserved names are below -- temporary names.
