I'm working on a similar tool (https://codeinput.com/products/merge-conflicts/online-diff), specifically focusing on how to use the diff results. For semantic parsing, I think the best option available right now is Tree-sitter (https://tree-sitter.github.io/tree-sitter), which has decent WASM support. If this interests you, feel free to shoot me an email. I'm always looking to connect with other devs who want to discuss this stuff.

Oh yeah tree-sitter it's a great foundation for semantic structure.

What I'm exploring is more about what we do with that structure once someone/smth starts generating thousands of changed lines: how to compress change into signals we can actually reason about.

Thank you for sharing. I'm actually trying your tool right now - it looks really interesting. Happy to exchange thoughts.
