The dbus package
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.
mapM_ putStrLn (sort names)
