Combinators

stdoutOf :: CreateProcess -> Maybe Handle

Retrieve the stdin handle associated with a CreateProcess

stdinOf :: CreateProcess -> Maybe Handle

Retrieve the stdout handle associated with a CreateProcess

stderrOf :: CreateProcess -> Maybe Handle

Retrieve the stderr handle associated with a CreateProcess

closing :: HasUseHandle a => Getter CreateProcess a -> CreateProcess -> IO ()

Close something with a prism into a non-standard Handle in a CreateProcess

inheriting :: Lens' a StdStream -> a -> a

Given a lens into a StdStream, overwrite to Inherit so that the stream inherits from its parent process

Given a lens into a StdStream, overwrite to CreatePipe, piping the process

handling :: Lens' a StdStream -> Handle -> a -> a

Given a lens into a StdStream and a handle, set the handle using UseHandle.
