A little Clojure-like LISP in JavaScript — this fork focuses on portable, standalone binaries and a minimal Docker image while keeping browser usage intact.

Quick start: standalone binaries

• Prebuilt Bun-compiled CLIs live in dist/ (e.g., wisp-bun-linux-x64).
• Run directly: ./dist/wisp-bun-linux-x64 --help.
• Build your own: make cli-bin (host arch) or make cli-bin-all for bun-linux-x64, bun-linux-arm64, bun-darwin-x64, bun-darwin-arm64.

Quick start: Docker image

• Scratch-based image published to GHCR (built from the Bun-compiled binary).
• Run: docker run --rm ghcr.io/rcarmo/wisp:latest --help.
• Use for compilation: docker run --rm -v "$PWD:/src" -w /src ghcr.io/rcarmo/wisp:latest myscript.wisp.

Browser usage (unchanged)

1. Read about the language essentials & documentation.
2. Drop wisp.min.js into your HTML code:

<script src="wisp.min.js"></script>

<script type="application/wisp">
  (alert "Hello world!")
</script>

<!-- Load from a file: -->
<script type="application/wisp" src="my-script.wisp"></script>

Build from source

• Install deps: bun install (preferred) or npm install.
• Build everything: bun run build (Makefile auto-detects Bun, falls back to Node).
• Tests: bun run test.
• Force Node: JS_RUNTIME=node make all.

About this fork

• Bun-first tooling for faster local builds and minified browser bundles.
• Self-contained Bun-compiled CLI binaries and a scratch-based Docker image targeting multiple architectures.

Wisp is currently in maintenance mode. We're merging PRs but not actively writing new code.
