Awesome project, you're inspiring me to pick back up a text editor project I had started to learn Rust a while back. Yours is much more featureful, however! By the way, if anyone else is thinking about doing the same, HN had a great discussion on an article (also very useful) on the various data structures one can use for text editors: https://news.ycombinator.com/item?id=11244103 https://news.ycombinator.com/item?id=11244103

Thanks for the link and the encouragement! You have your Rust project somewhere online? I'd love to take a look at it. I sometimes fantasize about rewriting Ewig in Rust, as a learning project (have been reading about it but didn't dare to write code in it yet). But I'd like to use RRB-Vector there too. Sadly, this data-structure is not really trivial to implement... (the concat algorithm in particular). Maybe one day I'll find the time :-)

  It's not on a public repo, and I abandoned it half-done a couple of years ago while using Rust Nightly, so it will need some work I think to run on current Rust. I stopped because I got frustrated and confused with Rust's lifetimes, and just quit Rust for over a year. Fortunately, a few months ago, after another attempt at Rust writing a simple ML-like language, something clicked and now I'm enjoying writing Rust. If you do attempt Rust, just expect to be frustrated for a while with Rust's ownership system, it's a new concept for almost everyone. I think it's kind of like monads in Haskell, you struggle with it until suddenly it "clicks" and then it doesn't seem very hard, but it then becomes hard to convey your understanding to someone else. Rewriting Ewig in Rust, including the persistent tree-based immutable vector, would be an excellent exercise. Indeed, just starting with the RRB-Vector would be a great project. By the way, your immutable data structures library is quite impressive, it would be nice to have such a library in Rust. As far as I know, there is no such maintained library of functional data structures in Rust.

I tried a rust one as well [1], (antirez based). It's a decent amount of fun, would like to try implementing some of the more interesting features/data structures. [1] https://github.com/khadiwala/kilo-rs https://github.com/khadiwala/kilo-rs
