#: pymod2pkg
`pymod2pkg` is a simple python module for translating python module names to
corresponding package names which is a common problem in the packaging world.
Note that [rdopkg](https://github.com/redhat-openstack/rdopkg) uses this
module to check whether packages corresponding to `requirements.txt` are
available across distros and more.
## Installation
### from source
If you want to hack `pymod2pkg` or just have the latest version without
waiting for next release, I suggest using the git repo directly a la
git clone https://github.com/openstack/pymod2pkg
cd pymod2pkg
python setup.py develop --user
### from PyPI
For your convenience, `pymod2pkg` is also available from the Cheese
Shop:
pip install pymod2pkg
## Usage
`module2package` is probably all you need, it accepts a module name to convert
and a linux distribution name as returned by `platform.linux_distribution()[0]`:
import pymod2pkg
pkg = pymod2pkg.module2package('six', 'Fedora')
There's not much more, really, so RTFS.
## Fixing/extending the map
Currently, only package maps for RPM-based systems are provided, but it'd be
nice to have all the distros covered and it's really easy to do.
See `*_PKG_MAP` and `get_pkg_map`, hack it to your liking and submit review by
git review
## Running the testsuite
Run tests by:
python tests.py
