# Contributing & Maintaining

## A brief explanation on the source code structure

This repository contains no source code, it only contains the scripts to package everything together and ship the `monaco-editor` npm module:

These packages are described in the root file called `metadata.js` and it is possible to create an editor distribution that contains only certain plugins by editing that file.

| [vscode](https://github.com/Microsoft/vscode) | [monaco-editor-core](https://www.npmjs.com/package/monaco-editor-core) | editor core functionality (language agnostic) is shipped out of vscode. |
| [monaco-languages](https://github.com/Microsoft/monaco-languages) | [monaco-languages](https://www.npmjs.com/package/monaco-languages) | plugin that adds colorization and basic supports for dozens of languages. |
| [monaco-typescript](https://github.com/Microsoft/monaco-typescript) | [monaco-typescript](https://www.npmjs.com/package/monaco-typescript) | plugin that adds rich language support for JavaScript and TypeScript. |

## Running the editor tests

```bash
/src/vscode> npm run monaco-editor-test
# or run a test page http://localhost:8080/monaco-editor/test/?editor=src
```

> Tip: All folders must be cloned as siblings.
