@mmmnt/feat-grammar

The TextMate grammar for .feat — the single highlighting artifact behind every surface. Editor extensions, websites, and any TextMate-compatible tool consume this package; the grammar is tested by tokenizing real corpus exemplars with vscode-textmate (the engine VS Code itself uses).

Websites (Shiki)

import { createHighlighter } from "shiki";
import featLanguage from "@mmmnt/feat-grammar";

const highlighter = await createHighlighter({
  themes: ["github-dark"],
  langs: [featLanguage],
});
const html = highlighter.codeToHtml(specText, { lang: "feat", theme: "github-dark" });

Editors

• VS Code / Windsurf / Cursor / Devin: install the feat-vscode extension (VS Code Marketplace + Open VSX) — it bundles this grammar.
• JetBrains IDEs: Settings → Editor → TextMate Bundles → add a directory containing feat.tmLanguage.json.
• GitHub.com rendering: requires a github-linguist submission (planned once the language has public usage).
