Here's a great one for Rust: https://bfnightly.bracketproductions.com/rustbook/chapter_0....

It looks like it's unfinished. At the bottom of the last existing chapter, it says "We now have the second-to-last section done!" and mentions something about building "the Abyss." I wonder if the author(s) meant to finish it but never returned from the depths...

In progress might be a better way to put it.

The copyright looks old on that page but if you view the source code for that chapter it was modified last month.

The author is pretty active on /r/roguelikedev and definitely still works on this and the original library
