Generate moon_zod schema from any JSON file with one click — copy ready-to-use @moon_zod code to your clipboard.

Features

CodeLens button — opens automatically when editing .json files
Context menu — right-click any JSON file and select "moon_zod: Copy Schema from Current File"
JSON Schema import — convert existing JSON Schema to moon_zod code via --from-json-schema
Powered by Betterlol/moon_zod — delegates schema inference and code generation to the real moon_zod library, so the output stays in sync with library updates

Requirements

MoonBit toolchain (moon CLI in PATH)
VS Code ^1.85.0

Installation

From VSIX

vsce package
code --install-extension vscode-moon-zod-schema-*.vsix

From Marketplace (once published)

Search "moon_zod Schema Generator" in the Extensions pane.

Usage

Open any .json file in VS Code
Click "Copy moon_zod Schema" in the editor top bar, or right-click → "moon_zod: Copy Schema from Current File"
The generated @moon_zod code is copied to your clipboard

The schema is generated via the bundled MoonBit package at gen/, which delegates to Betterlol/moon_zod for inference and code generation.

How It Works

The extension bundles a small MoonBit CLI tool (gen/) that runs under the hood:

moon run gen -- --verbose '<json>'

The output is parsed for ── Generated moon_zod Schema ──, and everything after that marker is copied to the clipboard.

The gen/ package uses:

@moon_zod.json_infer_schema — infer a schema from a raw JSON value
@moon_zod.schema_to_moon_zod_code — render the schema as MoonBit source code
@moon_zod.json_schema_to_moon_zod — convert JSON Schema to moon_zod code

You can also use the CLI standalone:

moon run gen -- '{"name": "Alice"}'
moon run gen -- --from-json-schema '{"type": "object", "properties": {...}}'
moon run gen -- --verbose '{"name": "Alice"}'

Development

# Install dependencies
moon add Betterlol/moon_zod

# Build & test
moon run gen -- '{"hello": "world"}'

# Package
