I've been toying around with tree-sitter and have seen the potential for a proper, non-regex based highlighter. It's really powerful because it actually parses the text into an AST. With the AST it's possible for example to make variables the same colour everywhere. A function passed as a parameter could be highlighted as a function even in the parameter list.

I'm happy to see that tree sitter highlighting on the web is finally a thing. This seems really solid although the bundle size is a lot.

I'm the author of the post, thanks for your feedback! I was inspired by your comment on HN a while back and started learning about this stuff, reading the source code of `memchr` was especially great.

You're totally right about the first part there was a serious consideration to add this to zig's standard library, there would definitely need to be a fallback to avoid the `O(m*n)` situation.

I'll admit that there are a lot of false assumptions at the end, you could totally specialize it for u8 and also get the block size according to CPU features at compile time with `std.simd.suggestVectorSize()`
