tree-sitter-ascript

A tree-sitter grammar for AScript — a small, dynamically-typed, JavaScript-flavored scripting language (.as files) with optional runtime-checked type contracts and a batteries-included standard library. This package provides incremental parsing plus a full set of editor query files (syntax highlighting, code folding, indentation, and more) for any editor or tool built on tree-sitter.

Install

npm:

npm install tree-sitter-ascript

Cargo (Cargo.toml):

[dependencies]
tree-sitter-ascript = "0.1"

Queries

The package ships the following tree-sitter query files under queries/:

• highlights.scm — syntax highlighting
• injections.scm — embedded-language injections
• locals.scm — local scope / definition & reference tracking
• folds.scm — code folding regions
• indents.scm — auto-indentation rules
• textobjects.scm — selection text objects (functions, classes, parameters, etc.)
• tags.scm — symbol tags for code navigation
• brackets.scm — matching-bracket pairs

Source of truth

This repo is a published mirror. The canonical grammar lives in the AScript monorepo (ascript-lang/ascript) at the top-level tree-sitter-ascript/ directory — the single source of truth for both this npm/cargo artifact and the AScript engine itself (the engine's build.rs compiles the same src/parser.c directly). Changes are made there and mirrored here via git subtree (see scripts/sync-grammar.sh / the mirror-grammar workflow in the monorepo). When the grammar changes, regenerate parser.c with tree-sitter generate --abi 14 so both consumers stay in sync.
