Streaming interface to system processes.

Concurrent, streaming access to the input and outputs of system processes.

process-streaming

A library for interacting with system processes in a streaming fashion.

The basic goals:

• Concurrent, streaming access to stdin, stdout and stderr...

• ...all the while preventing deadlocks caused by mishandling of the streams.

• Easy integration with consumers from pipes, parsers from pipes-parse and folds from foldl.

• Facilitate the use of sum types to signal failures, when desired.

• No fussing around with process handles: wait for the process by waiting for the IO action, terminate the process by killing the thread executing the IO action.
