hi,
one of the rex maintainers here. I personally don't consider rex as a dead project, despite the low activity. I wish I could work on it more, but it proves to be hard to find the quality time simply because life happens (in chronological order: being knocked out of tech for a year due to burnout, changing jobs, moving to a another city hundreds of kilometres away, getting married, selling/renovating flats in another country).
In fact, I started to organize an open source contribution meetup locally so I have some dedicated time to work on non-paid open source stuff again (mostly rex) in a managed fashion. So at least once a month I'm sitting down and going through open issues and pull requests. Plus I committed a contribution guide earlier this year that should make many workflows around the project smoother.
Maintaining all the surrounding additional stuff (website, CI, build pipelines, repos, etc. + sister projects like repositorio and rex-recipes + support over IRC/mailing list) are currently beyond me. If anyone is interested in helping out, I'm happy to discuss ideas and review code.
All help are welcome :)
Have fun,
FErki
