This started as a hard requirement for my TUI-based editor application, it ended up going in a few different directions.A suite of tools that help with semantic code entities: https://github.com/odvcencio/gts-suiteA next-gen version control system called Got: https://github.com/odvcencio/gotI think this has some pretty big potential! I think there's many classes of application (particularly legacy architecture) that can benefit from these kinds of analysis tooling. My next post will be about composing all these together, an exciting project I call GotHub. Thanks!

Could you build this?

No Porting Tree-sitter—a complex C incremental GLR parsing library with intricate memory management and dynamic state tracking—purely into Go requires deep compiler design and formal grammar parsing expertise.

What it would actually take: The implementation requires translating Tree-sitter's core C runtime into idiomatic Go while maintaining identical GLR (Generalized LR) parsing semantics, error recovery algorithms, and binary compatibility with generated parser tables. The stack involves low-level Go unsafe pointers, custom allocators or slices to manage syntax trees efficiently, and comprehensive fuzz testing against the original C test suites. This demands specialized expertise in compiler construction and parser runtime internals.
