tree-sitter grammar for the Fe language.

This repository is a generated mirror. The grammar source of truth lives in argotorg/fe at crates/tree-sitter-fe. There, the generated parser (parser.c, grammar.json, node-types.json, wasm) is not tracked — it bloats diffs. This repo regenerates and commits those artifacts so editors and other tools have a stable git tree to clone and build, with src/parser.c present.

A scheduled workflow (.github/workflows/sync.yml) regenerates the grammar from argotorg/fe:

• main tracks argotorg/fe@master; it is auto-committed whenever the grammar changes. Use this to test in-progress grammar work.
• Release tags (e.g. v26.3.0) mirror the corresponding argotorg/fe release and are the refs editor integrations should normally pin. Each tag also gets a GitHub release with the compiled tree-sitter-fe.wasm attached.

The .source-commit file records the exact argotorg/fe commit each revision was generated from.

To regenerate locally or point main at an arbitrary fe ref, run the sync script (or the Sync grammar from fe workflow's manual dispatch):

scripts/sync-from-fe.sh <branch|tag|sha>   # default: master

It needs node/npm (installs the pinned tree-sitter CLI). Building the wasm additionally needs emcc (Emscripten).

Point your editor integration at this repo with the standard root layout (src/parser.c, src/scanner.c, queries/), pinning a release tag:

• Zed: repository = "https://github.com/fe-lang/tree-sitter-fe", commit = "<sha>"
• Emacs (treesit): ("https://github.com/fe-lang/tree-sitter-fe" "v26.3.0" "src")
• Neovim / nvim-treesitter: clone this repo at the tag and compile src/parser.c
