## A brief explanation on the source code structure

This repository contains source code only for Monaco Editor Languages, the core editor source lives in the [vscode repository](https://github.com/microsoft/vscode).

## Contributing a new tokenizer / a new language

Please understand that we only bundle languages with the monaco editor that have a significant relevance (for example, those that have an article in Wikipedia).

- create `$/src/basic-languages/{myLang}/{myLang}.contribution.ts`
- create `$/src/basic-languages/{myLang}/{myLang}.ts`
- create `$/src/basic-languages/{myLang}/{myLang}.test.ts`
- edit `$/src/basic-languages/monaco.contribution.ts` and register your new language
- create `$/website/index/samples/sample.{myLang}.txt`

```js
import './{myLang}/{myLang}.contribution';
```
