Pieshell is a Python shell environment that combines the expressiveness of shell pipelines with the power of python iterators.

This release adds support for async/await and async iterators for all shell pipelines, as well as MacOS X support.

Pieshell can be used as an interactive shell replacing e.g. bash or imported as an ordinary python module, providing a superset of the functionality of subprocess.Popen etc.

Example of what Pieshell lets you do:

for name in ls | grep("-e", ".pyc"):
rm(name)
