Wrapper for doing beautiful commands

Project description

Capris is a MIT-licensed Python library built for writing composable apps that leverage the command line.

A simple example of writing your own git wrapper, complete with other command-line utilities that you love and use on a daily basis:

>>> from capris import Command
>>> git, grep = Command('git'), Command('grep')

>>> pipe = git.log(n=10, pretty="oneline") | grep(r'[a-f0-9]\{40\}', o=None)
>>> str(pipe)
"git log -n 10 --pretty='oneline' | grep -o '[a-f0-9]\{40\}'"

>>> response =
>>> response.status_code
>>> print response.std_out

capris allows you to write code that just calls commands and helps you focus on writing the commands that you need, not the code required to handle calling and getting responses from the commands. capris does all of the mucking around with strings and escaping for you.
