tree-sitter-grammar

Comprehensive tree-sitter grammar development guide covering the JavaScript DSL, precedence systems, conflict resolution, external scanners, state explosion mitigation, and best practices distilled from studying 17 reference grammars and the official documentation. Use when building or modifying tree-sitter grammars, debugging parse errors, optimizing parser generation, or understanding tree-sitter internals. Trigger: user mentions 'tree-sitter', 'grammar.js', 'parser generation', 'tree-sitter conflicts', 'external scanner', 'state explosion', or asks about tree-sitter grammar development.

Tree-Sitter Grammar Development Guide

Complete reference for building tree-sitter parsers, distilled from the official tree-sitter documentation (v0.26.x), 17 reference grammars, and practical experience.

Reference grammars cloned at ~/projects/tree-sitter-jai/reference-grammars/ for direct study:

tree-sitter/ — Official documentation and source
tree-sitter-go/ — Clean baseline (983 lines, 6 prec levels, no scanner)
tree-sitter-rust/ — Well-structured (1600+ lines, 15 prec levels, scanner for raw strings)
tree-sitter-odin/ — Closest to Jai (960 lines, 11 prec levels, no scanner)
tree-sitter-d/ — Feature-rich (2580 lines, scanner for heredocs/delimited strings)
tree-sitter-zig/ — Comptime system (named prec levels, 6 conflicts)
tree-sitter-c/, tree-sitter-cpp/ — C family patterns
Plus: java, javascript, typescript, python, ruby, elixir, haskell, nickel, swift

See references/cheatsheet.md for the full development cheatsheet.

actor-pattern

Apply the actor pattern for thread-safe state management. Use when: (1) multiple threads/goroutines need shared mutable state, (2) replacing mutex-locked structs or atomic patterns, (3) building a service layer that owns in-memory state plus persistence, (4) application has distinct operational modes (setup, running, error) requiring a coordinator that manages sub-actors, (5) the user mentions 'actor pattern', 'goroutine event loop', 'channel-based state management', or 'actors managing actors'. Supports Go, Jai, C, Rust, Odin, and Zig.

jai-language

Comprehensive Jai programming language reference and cheat sheet. Use when working with Jai code, tree-sitter-jai grammar development, or answering questions about Jai syntax and semantics. Covers declarations, types, control flow, directives, metaprogramming, and all language features. Trigger: user mentions 'Jai', 'Jai language', 'tree-sitter-jai', or asks about Jai syntax.

interface-first

Design around contracts, not implementations. Use when: (1) building multi-step features where placeholders would otherwise accumulate, (2) expensive or stateful objects need mock and real implementations (databases, caches, external services), (3) scaling fault lines exist where in-proc vs. remote implementations should be swappable, (4) test mocks need to verify behavior through observation hooks, (5) designing a system that may need to scale from single-process to distributed without a rewrite, (6) the user mentions 'interface first', 'mock implementation', 'store interface', 'transaction boundary', 'scaling fault line', 'single binary', 'deployment topology', or 'test contract'. Primarily Go, but applicable to any language with interface-like constructs (Rust traits, Java/Scala interfaces).
