Subtask

A simple wrapper around subprocess.Popen to reduce the painfulness of running multiple processes concurrently.

task = Subtask(['python', 'hello.py'])
task.wait()
assert task.read_stdout().strip() == "Hello, world!"

What is Subtask for?

Subtask makes it easy to keep track of many concurrent subprocesses. It makes it much easier to capture outputs and give inputs to these processes.

What is Subtask not for?

Subtask is designed for simplicity. It should not be used if you want high performance, or to chain outputs for many files together.
