Network.MPD

Description

An MPD client library. MPD is a daemon for playing music that is controlled over a network socket.

To use the library, do:

import qualified Network.MPD as MPD
Synopsis

Basic data types

class (Monad m, MonadError MPDError m) => MonadMPD m #

A typeclass to allow for multiple implementations of a connection to an MPD server.

Minimal complete definition

open, close, send, getPassword, setPassword, getVersion

Instances

MonadMPD MPD # 
Instance details

Defined in Network.MPD.Core

Methods

open :: MPD () #

close :: MPD () #

send :: String -> MPD [ByteString] #

getPassword :: MPD Password #

setPassword :: Password -> MPD () #

getVersion :: MPD (Int, Int, Int) #

data MPD a #

The main implementation of an MPD client. It actually connects to a server and interacts with it.

To use the error throwing/catching capabilities:

import Control.Monad.Error (throwError, catchError)

To run IO actions within the MPD monad:

import Control.Monad.Trans (liftIO)

Eq ACKType #

Defined in Network.MPD.Core.Error

Methods

(==) :: ACKType -> ACKType -> Bool

(/=) :: ACKType -> ACKType -> Bool

type Response = Either MPDError #

A response is either an MPDError or some result.

type Host = String #

type Port = Integer #

type Password = String #

Connections

withMPD :: MPD a -> IO (Response a) #

A wrapper for withMPDEx that uses localhost:6600 as the default host:port, or whatever is found in the environment variables MPD_HOST and MPD_PORT. If MPD_HOST is of the form "password@host" the password will be supplied as well.

Examples:

withMPD $ play Nothing
withMPD $ add_ "tool" >> play Nothing >> currentSong

withMPD_ #

Arguments

:: Maybe String

optional override for MPD_HOST

-> Maybe String

optional override for MPD_PORT

-> MPD a 
-> IO (Response a) 

Same as withMPD, but takes optional arguments that override MPD_HOST and MPD_PORT.

This is e.g. useful for clients that optionally take --port and --host as command line arguments, and fall back to withMPD's defaults if those arguments are not given.

withMPDEx :: Host -> Port -> Password -> MPD a -> IO (Response a) #

The most configurable API for running an MPD action.

data Query #

An interface for creating MPD queries.

For example, to match any song where the value of artist is "Foo", we use:

Artist =? "Foo"

We can also compose queries, thus narrowing the search. For example, to match any song where the value of artist is "Foo" and the value of album is "Bar", we use:

Artist =? "Foo" <> Album =? "Bar"
