A thing has happened! The SwiftTreeSitter project has been transferred to the tree-sitter organization.
I'll still be involved, but it's now definitely more official.

did the folks behind tree-sitter ever get some sort of award? with hindsight, it was industry-changing stuff — completely transformed the landscape of syntax highlighting.

expectation: tree-sitter grammars are large because, y'know, LR parsing, big tables, complicated grammars, idk.
reality: I fucking linked the WHOLE tree-sitter crate from each of them, complete with regex, aho-corasick, memchr, etc. etc.

You know, it would be super convenient if you could get a report of the test failures of your tree sitter corpus as an HTML file. You could even have syntax highlighting, perhaps using something like tree sit–Never mind.

Big fan of @fasterthanli.me’s new library wrapping tree-sitter grammars up with a really nice Rust API. Spent a bit of the afternoon replacing a Syntect-based highlighting setup with an Arborium-based setup and much prefer it—and tree-sitter grammars are much more robust than old Textmate grammars!

I'm happy to announce arborium, a collection of 96 tree-sitter grammars (so far) that compile cleanly as crates and npm packages, for desktop & wasm.
It comes with themes, two rustdoc integrations, a clean HTML+ANSI highlighter, get it while it's hot:

I'm learning a lot of things dealing with tree-sitter grammars. For example, one lean is equal two SQLs
(ie. lean's grammar compiles to 3 million LOC)
