pc 0.0.2

process control -- easy fork-exec and pipe with I/O redirection

Design goals:

• Easy to fork-exec commands, wait or no wait

• Easy to capture stdout/stderr of children (command substitution)

• Easy to express I/O redirections

• Easy to construct pipelines

• Use short names for easy interactive typing

In effect, make Python a sane alternative to non-trivial shell scripts.

Technically, pc.py is a layer on top of subprocess. The subprocess module support a rich API but is clumsy for many common use cases, namely sync/async fork-exec, command substitution and pipelining, all of which is trivial to do on system shells.

Documentation is at <http://github.com/aht/pc.py/>.

This module depends on Python 2.6, or where subprocess is available. Doctests require /bin/sh to pass. Tested on Linux.

This is an alpha release. Some features are unimplemented. Expect bugs.
