Description

This module provides a server process (implemented using eprocess) that can receive and run actions in the Interpreter monad.

Synopsis

data ServerHandle start :: IO ServerHandle stop :: ServerHandle -> IO () runIn :: ServerHandle -> InterpreterT IO a -> IO (Either InterpreterError a) asyncRunIn :: ServerHandle -> InterpreterT IO a -> IO (MVar (Either InterpreterError a)) flush :: ServerHandle -> IO (Either InterpreterError ())

Types

data ServerHandle Source

The server handle. It's returned on process creation and should be used afterwards to send messages to it

Functions

start :: IO ServerHandle Source

Starts the server. Usage: handle <- start

stop :: ServerHandle -> IO () Source

Stops the server. Usage: stop serverhandle

runIn Source

:: => ServerHandle The action to be run -> InterpreterT IO a -> IO (Either InterpreterError a) Runs the action. Usage: result <- runIn serverhandle action

asyncRunIn Source

:: => ServerHandle The action to be run -> InterpreterT IO a -> IO (MVar (Either InterpreterError a)) Asynchronically runs an action and returns the MVar that will be filled with the result when it's there. Usage: mvar <- asyncRunIn serverhandle action

flush Source

:: ServerHandle The handle of the server that will run the action -> IO (Either InterpreterError ()) The meaningful results are stored in the corresponding mvars Runs all the pending actions (those that where run using asyncRunIn. Usage: flush serverhandle
