Make a release please
Because this package is needed for kajiki, I need to build a Fedora package. Please make a release to make this easier. Thank you.
0.0.2: test suite is failing
I'm packaging your module as an rpm package so I'm using the typical PEP517 based build, install and test cycle used on building packages from non-root account.
python3 -sBm build -w --no-isolation- because I'm calling
buildwith--no-isolationI'm using during all processes only locally installed modules - install .whl file in </install/prefix>
- run pytest with PYTHONPATH pointing to sitearch and sitelib inside </install/prefix>
Here is pytest output:
