Why remove this and break lots of plugins in the ecosystem? I don't see this tied to an issue with discussion or anything like that.

A few thoughts:

Version 10.0.5 still supports coffeescript. For those still using hubot and coffeescripts, they should set the hubot peer dependency to version 10.

I haven’t seen any GitHub issues about breaking plugins. I’d love to know how many people are still using hubot. And hubot with coffeescripts.

Removing coffeescript was on the roadmap issue #1658

Some background:
Development on hubot stalled sometime around 2017. I asked to be a maintainer and was added to the repo this year (at least I think it was this year). My objective was to modernize the code base, and try to pick up where the other maintainers left off with the goals in the evolution repo.

in my research, I found that almost every repo I found was last updated many years ago. Leaving me with the impression that the hubot ecosystem has gone stale.

Being the 1 person maintaining it, I’ve been trying to reduce the maintenance surface area. Specifically reducing dependencies. I still get dependabot notifications for the yo generator repo. Gotta figure out what to do with that.

I think there’s better adoption for ES6, which is my motivation to modernize hubot and evolve it to a new vision having been left stale for so long.

With all those points in mind, I removed coffeescript in v11 as I try to incorporate some of the goals initially defined in the evolution repo and figure out where hubot now fits in todays universe.

Are you still using hubot? With coffeescripts? I’d love to hear your story.
