emacs-ts-mode

Comprehensive guide for building Emacs tree-sitter major modes. Covers the full treesit.el API, font-lock rules, indentation, navigation, imenu, and best practices distilled from studying 17+ production modes. Use when creating or modifying an Emacs tree-sitter mode (*-ts-mode), working with treesit-font-lock-rules, treesit-simple-indent-rules, or any Emacs tree-sitter integration. Trigger: user mentions 'ts-mode', 'tree-sitter mode', 'treesit', 'font-lock-rules', 'indent-rules', or asks about Emacs tree-sitter major mode development.

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).

Emacs Tree-Sitter Mode Development Guide

Complete reference for building Emacs 29+ tree-sitter major modes, distilled from the Emacs core treesit.el API and 17+ production modes (built-in: go, rust, c/c++, elixir, python, ruby, typescript; third-party: clojure, ada, haskell, scala, templ, swift, zig, and others).

Reference modes are cloned at ~/projects/jai-ts-mode/reference-modes/ for direct study.

Key built-in files to consult:

reference-modes/emacs/lisp/treesit.el — core infrastructure (5835 lines)
reference-modes/emacs/lisp/progmodes/go-ts-mode.el — clean standalone mode
reference-modes/emacs/lisp/progmodes/rust-ts-mode.el — advanced font-lock patterns
reference-modes/emacs/lisp/progmodes/c-ts-mode.el — complex dual-language, preprocessor handling
reference-modes/emacs/lisp/progmodes/c-ts-common.el — reusable C-family utilities

Key third-party modes:

reference-modes/clojure-ts-mode/ — best-documented, has doc/design.md
reference-modes/ada-ts-mode/ — most feature-complete single-language mode
reference-modes/elixir-ts-mode/ — upstreamed to Emacs core, multi-language embedding

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