grout13

grout13 is the public Git module for Grout's compact JS13k-style atlas compiler and generated runtime. It keeps the reviewed eight-export Grout13 facade self-contained so a tiny-game project can load a browser artifact without installing grout-render or waiting for an npm release.

Repository: https://github.com/Shoozes/grout13

Browser CDN usage

The Git-backed jsDelivr URL is the intended preview path:

<script src="https://cdn.jsdelivr.net/gh/Shoozes/grout13@main/dist/grout13.global.min.js"></script>
<script>
  const compiled = GROUT13.compileGrout13Atlas([
    { name: 'player', spec: { w: 2, h: 2, steps: [{ type: 'fill', col: 1 }] } }
  ]);
</script>

For a browser ESM import:

<script type="module">
  import { compileGrout13Atlas } from
    'https://cdn.jsdelivr.net/gh/Shoozes/grout13@main/dist/grout13.mjs';
</script>

Use @main for the current public preview. Pin a commit SHA when a game needs reproducible bytes. This repository is a public Git/CDN delivery path, not an npm release; package.json is retained for local builds and type-aware editor tooling.

Public facade

The module preserves the reviewed Grout13 v1 names:

• GROUT13_FORMAT_VERSION
• DEFAULT_GROUT13_ATLAS_OPTIONS
• compileGrout13Atlas
• decodeGrout13Atlas
• createGrout13RuntimeSourceFromCompiled
• createGrout13BundleSourceFromCompiled
• escapeGrout13InlineScriptSource
• getGrout13PayloadBytes

The compiler creates a single-page indexed atlas payload from Grout specs and can emit a matching small canvas, RGBA, or indexed runtime. Research-only layout and encoder candidates are intentionally excluded from this public facade.

Build and verify

The committed dist/ files are the consumable Git artifacts. To rebuild them from the bundled source and run the ESM/global smoke checks:

npm install
npm run verify

The module has no runtime dependency on npm, Phaser, or a network request.
