makecode

MKC - command line tool for MakeCode editors

This package includes a tool that can compile MakeCode (PXT) projects by downloading parts of a released MakeCode web app and running them in node.js.

This is different than pxt command line tool, which is used primarily during development of MakeCode editors.

Installation

To install globally, run

npm install -g makecode

To update the client,

npm install -u -g makecode

Usage

In a folder with pxt.json file, run:

> makecode

You can also pass --hw f4, --hw d5 etc. Try --hw help to get a list. Use makecode -j to build JavaScript (it defaults to native).

The tool is configured with optional mkc.json file. Example:

{
    "targetWebsite": "https://arcade.makecode.com/beta",
    "hwVariant": "samd51",
    "links": {
        "jacdac-services": "../../pxt-jacdac-services"
    },
    "overrides": {
      "testDependencies": {}
    }
}

All fields are optional.

• targetWebsite says where to take the compiler from; if you omit it, it will be guessed based on packages used by pxt.json; you can point this to a live or beta version of the editor, as well as to a specific version (including SHA-indexed uploads generated during PXT target builds)
• hwVariant specifies default hardware variant (currently only used in Arcade); try --hw help command line option to list variants
• links overrides specific packages; these can be github packages or built-in packages
• overrides is used to override specific keys in pxt.json

You can use --config-path to build for a different configuration, eg. makecode -c mkc-arcade.json.

Local development

This section describes how to build mkc itself.

• install node.js
• run

npm install

• start the build

npm run watch

Releases

A new release will be automatically generated by the build system based on these commit naming guidelines.

• feat: A new feature
• fix: A bug fix
• docs: Documentation only changes style: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
• refactor: A code change that neither fixes a bug nor adds a feature
• perf: A code change that improves performance
• test: Adding missing or correcting existing tests
• chore: Changes to the build process or auxiliary tools and libraries such as documentation generation

TODO

• allow updating shims.d.ts/enums.d.ts
