Description

  • https://github.com/tree-sitter/tree-sitter (GLR)
    • @matklad pointed it out as a possible parser generator for Rust's libsyntax
    • has incremental reparsing but no dynamic ambiguity introspection (AFAICT?)
      • we should look closer at its incremental capabilities
    • C API, with bindings in many other languages
      • we could also provide a C API and/or just generate source for other languages

Contributor guide

Research direction
Review tree sitter's documentation and source code to understand its incremental reparsing and dynamic ambiguity introspection. Evaluate whether it can serve as a replacement for GLL in Rust's libsyntax.
