Alternative lp2gh JSON Importer for Mixxx issue migration
You can install this like this:
$ python3 -m venv venv
$ source venv/bin/activate
$ pip install PyGithub
To use it, you first need to obtain a bugs and milestone json file from lp2gh:
https://github.com/termie/lp2gh/blob/master/docs/moving_issues.rst#exporting-your-bugs
https://github.com/termie/lp2gh/blob/master/docs/moving_issues.rst#exporting-your-milestones
You can use it like this:
$ python json2github.py --repo Holzhaus/mixxx-gh-issue-migration --token mytoken --output-file=mixxx_bugs.json mixxx_bugs.json mixxx_milestones.json
