pip-pop

Working with lots of requirements.txt files can be a bit annoying. Have no fear, pip-pop is here!

(work in progress)

Planned Commands

$ pip-diff [--fresh | --stale] <reqfile> <reqfile>

Generates a diff between two given requirements files. Lists either stale or fresh packages.

$ pip-grep <reqfile> <package>...

Takes a requirements file, and searches for the specified package (or packages) within it. Essential when working with included files.

Possible Future Commands

• Install with blacklisting support (wsgiref, distribute, setuptools).

Development

To run the tests:

1. pip install -r requirements.txt
2. tox

Building artifact for buildpacks

We need to create a tarball that contains a distribution of this repo (as a tarball) along with docopt

1. Create a tarball of the pip-pop code (python setup.py sdist)
2. Download the latest artifact from buildpacks.cloudfoundry.org (wget https://buildpacks.cloudfoundry.org/dependencies/manual-binaries/pip-pop/pip-pop-0.1.3-fc106ef6.tar.gz)
3. Extract the docopt tarball into the dist directory (tar xf pip-pop-0.1.3-fc106ef6.tar.gz -C dist docopt-0.6.2.tar.gz)
4. Create a new tarball containing the new pip-pop tarball and the docopt tarball (tar czf pip-pop.tgz -C dist ./)
5. Rename the file to include the version and the first 8 characters of it's sha256 (mv pip-pop.tgz pip-pop-0.1.4-$(shasum -a256 pip-pop.tgz | cut -c1-8).tar.gz)
