Documentation
data ChildProcess Source
A running process
data PosixProcess Source
Describes configuration options for the process.
linemode :: Bool -> Config PosixProcessSource
arguments :: [String] -> Config PosixProcessSource
Set command arguments
appendArguments :: [String] -> Config PosixProcessSource
Append command arguments
environment :: [(String, String)] -> Config PosixProcessSource
Set the process' environment.
toolName :: String -> Config PosixProcessSource
The name of the tool, used in error messages and in the debug file.
newChildProcess :: FilePath -> [Config PosixProcess] -> IO ChildProcessSource
Starting a new ChildProcess
sendMsg :: ChildProcess -> String -> IO ()Source
Sends a String to the ChildProcess, adding a new line for line mode.
sendMsgRaw :: ChildProcess -> CStringLen -> IO ()Source
Writes a CStringLen to the child process. It does not append a newline.
readMsg :: ChildProcess -> IO StringSource
Reads a string from the ChildProcess
waitForChildProcess :: ChildProcess -> IO ChildProcessStatusSource
Waits for the ChildProcess to exit or be terminated
