monaco-textmate with grammars for most languages

See grammars/ for list of all the languages this package ships with

This package exposes LanguageRegistry class which has sweet lookup functions for language grammars.

You can get Grammar/Tokenizer either by language ID or file extension or even MIME type.

Not all grammars have been "registered/activated" for use due to lack of time, so PR's would be appreciated. To "register/activate" a language, every directory in grammars/ must have atleast one [lang-ext].config.json file that looks like this:

{
    "id": "typescript",
    "scopeName": "source.ts",
    "extensions": [".ts"],
    "mimeType": ["application/typescript"]
}

Usage

npm i monaco-textmate-languages

You must install all the peer dependencies yourself

import { LanguageRegistry } from 'monaco-textmate-languages'

const langRegistry = new LanguageRegistry({
    basePath: 'node_modules/monaco-textmate-languages',
    textFetcher: (uri) => (await fetch(uri)).text(),
    // `jsonFetcher` also works (you must provide either of those)
    // jsonFetcher: (uri) => (await fetch(uri)).json(),
})

langRegistry.getLanguageGrammarByExtension('.tsx')
    .then(grammar => {
        const tokens = grammar.tokenizeLine(`class App extends Component {}`)
        // ...
    })
