I've been learning a lot lately by following along with the development of xi[1], a new text editor written in Rust. Through reading that project's RFCs I've then come across other interesting projects, like swiobe[2] and wi[3].
What are the other canonical resources on this topic? It feels like tons of the interesting thought is scattered around various blogs and usenet posts and the like. I'd love to create a nice collection of good writing on text-editing / tools, but I'm not sure where to start.

Kakoune[1] has been posted recently here on HN to great reception. As a C++ developer, I think it has a very high quality codebase, especially considering how non-trivial it is.
As a user, it's been my main text editor for over a year.
It also has a vibrant community, jump in on IRC if you have questions or ideas.
