`envoy`-like abstraction of subprocess

Question

I was really excited about the Envoy project when I first heard about it. Having a sane API for subprocess is something I very much need.

However, envoy seems not to be maintained anymore. The last commit was made 10 months ago, and the last release was made 2 years ago. There are a bunch of serious bugs in it that I reported a long time ago, but were not fixed.

I'm looking for an alternative. Does anyone know of a Python package that does the same thing as Envoy (gives a good API to subprocess), except it's actively maintained?

I asked him whether he's aware of any alternatives, but he ignored me. — Ram Rachum, Jan 01 '14 at 19:40
"Ignoring" is a strong word -- many authors of popular things tend to get busy and overloaded with work. Give it time. — Markus Unterwaditzer, Jan 01 '14 at 19:42
@MarkusUnterwaditzer I emailed him two weeks ago. He might answer someday, but I wouldn't hold my breath. I could have used a happier word than "ignoring" but I find that using happy words to describe a sad reality doesn't really make the reality happier. — Ram Rachum, Jan 01 '14 at 20:45

There is the sarge package, available with: pip install sarge

It is documented here: http://sarge.readthedocs.org/en/latest/tutorial.html#installation-and-testing

It seems to be actively maintained & the maintainer is a frequent user of stack overflow (see one of their posts on the topic here: https://stackoverflow.com/a/11032170/2942522 )

A snippet from the sarge docs & one of the usage examples provided:

"If you want to interact with external programs from your Python applications, Sarge is a library which is intended to make your life easier than using the subprocess module in Python’s standard library."

>>> from sarge import run, Capture
>>> p = run('echo foo; echo bar; echo baz', stdout=Capture())
>>> p.stdout.readline()
'foo\n'
>>> p.stdout.readline()
'bar\n'
>>> p.stdout.readline()
'baz\n'
>>> p.stdout.readline()
''

The API is not as nice as `envoy`, but at least it's maintained. Answer accepted. — Ram Rachum, Jan 05 '14 at 14:05
