Library

Reusable rendering API

Use checked rendering, JSON helpers, dotted lookups, strict diagnostics, and bundle APIs from another MoonBit package.

CLI

Tooling-friendly workflows

Render from inline templates or files, validate multi-file bundles, export plans, and scan variable or partial references before integration.

Reports

Evaluator-facing evidence

Generate scenario reports, official spec compatibility reports, and downstream consumer proof with reproducible command lines.

Playground

Browser-facing demo

The local Vue playground lets users edit template, JSON context, and partials while the MoonBit engine handles rendering and diagnostics underneath.

Positioning

Why this project matters in MoonBit

Compared with ad hoc string concatenation

Moon Mustache gives reusable template syntax, better diagnostics, partial reuse, and more stable downstream workflows.

Compared with a contest-only prototype

This repository includes package publication, reports, CI, governance, downstream proof, and a browser-facing showcase layer.

Compared with building a custom template language

Mustache semantics are smaller, easier to trust, and already familiar across ecosystems, which lowers adoption friction for MoonBit users.
