I want to get it!

Okay, then please use pip to do so:

pip install pipin-req

Yeah, pipin was already taken, so sad. :(

How do I use it?

Pipin is meant to be used from the command line. Just pass it the requirement file in which you want to pin versions:

pipin requirements.txt

It also works with multiple filenames:

pipin requirements/docs.txt requirements/tests.txt

For each package it encounters that doesn't have a pinned version, pipin will search in your python environment for that package. If it find a matching package, its version will be used.

Why should I use it?

My use case was templating. When I create a project, I have a bunch of unpinned dependencies (as I want to begin a project with latest versions). I made this project to pin their versions once my virtualenv is setup.

Why the name pipin?

It's the contraction of pip and pin. A simple word play!
