"Tree-sitter - a new parsing system for programming tools" by Max Brunsfeld

Here is a small work I did a few years ago based on top of tree-sitter - https://github.com/autosoft-dev/tree-hugger

Marijn Haverbeke is also working on a re-implementation of Tree Sitter for JavaScript, called lezer. I believe it is how they plan on writing syntax highlighters for CodeMirror 6
