helix

Helix is actively developed, they just haven’t cut a release since July last year. Most recent major feature to land in master was workspace trust. The Scheme-based plugin system (https://github.com/mattwparas/helix/tree/steel-event-system) is almost ready to go. The plan is to merge it to master after the next release, whenever they get round to that. It’s easy to build from source though, I’ve been using it daily for over a year, and there already are several dozen reasonably sophisticated plugins available. You can browse a list of mine here: https://github.com/stars/waddie/lists/helix-plugins-steel-li...

There is a working prototype (that's gone as far as implementing a vim-dirvish picker): https://github.com/mattwparas/helix/tree/mwp-steel-integrati... The maintainers are collaborating with the dev and hope to get a PR open sometime this upcoming year.
