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)
