gotreesitter is a pure-Go reimplementation of the tree-sitter runtime with no CGo dependency, no C toolchain requirement, and WASM compatibility. It supports 205 language grammars, incremental parsing, S-expression queries, syntax highlighting, and symbol tagging. Benchmarks show incremental edits are ~90x faster than the CGo binding (1.38 μs vs 124 μs), and full parses are ~1.5x faster. The architecture includes a table-driven LR(1)/GLR parser, DFA lexer, arena allocator, external scanner VM, and lazy-loaded compressed grammar blobs. It eliminates cross-compilation issues, CI C-toolchain requirements, and CGo boundary problems with race detectors and fuzzers.
