pippy - Faster installs!
pippy is a pip extension that will allow you to keep local copies of prebuilt python packages. It’s main purpose is to be used with virtstrap so that virtstrap can create copies of each project without ever having to download or build anything. It accomplishes this only when it knows the exact version of the package you wish to download. Otherwise it behaves just as pip would behave.
Since virtstrap generates a VEfile.lock (similar to Ruby Bundler’s Gemfile.lock). Virtstrap tracks the exact version of the software you’re using. For this very reason, pippy is planned to be included in virtstrap.
By default pippy stores all of the packages in ~/.pippy. To change this directory just change the environment variable PIPPY_CACHE to point to the desired directory. The folder structure for the storage is this:
~/.pippy packages/ source/ # <- stores the sources for packages package-name/ .. tons of zips/tars .. package-name/ package-name/ cpython/ # <- stores builds for cpython 2.5/ # <- stores builds for python 2.5 package-name/ .. tons of tars .. 2.6/ # <- for python 2.6 ... more python versions ... pypy/ # <- stores builds for pypy ... more implementations ...
The CLI currently only accepts one argument, a pip requirements file:
It is highly suggested that the requirements file use only exact specifications for the requirements.
Eventually, pippy will provide almost the same commands as pip, plus some additional commands for managing the installed packages.
These issues will be rectified as soon as possible
