Monaco Editor

The Monaco Editor is the code editor which powers VS Code, with the features better described here.

Please note that this repository contains no source code for the code editor, it only contains the scripts to package everything together and ship the monaco-editor npm module.

Try it out

Try the editor out on our website.

Installing

$ npm install monaco-editor

You will get:

• inside esm: ESM version of the editor (compatible with e.g. webpack)
• inside dev: AMD bundled, not minified
• inside min: AMD bundled, and minified
• inside min-maps: source maps for min
• monaco.d.ts: this specifies the API of the editor (this is what is actually versioned, everything else is considered private and might break with any release).

It is recommended to develop against the dev version, and in production to use the min version.

Documentation

• Learn how to integrate the editor with these complete samples.
  • Integrate the AMD version.
  • Integrate the ESM version
• Learn how to use the editor API and try out your own customizations in the playground.
• Explore the API docs or read them straight from monaco.d.ts.
• Read this guide to ensure the editor is accessible to all your users!
• Create a Monarch tokenizer for a new programming language in the Monarch playground.
• Ask questions on StackOverflow! Search open and closed issues, there are a lot of tips in there!

FAQ

❓ What is the relationship between VS Code and the Monaco Editor?

The Monaco Editor is generated straight from VS Code's sources with some shims around services the code needs to make it run in a web browser outside of its home.

❓ What is the relationship between VS Code's version and the Monaco Editor's version?

None. The Monaco Editor is a library and it reflects directly the source code.

❓ I've written an extension for VS Code, will it work on the Monaco Editor in a browser?

No.

Note: If the extension is fully based on the LSP and if the language server is authored in JavaScript, then it would be possible.

❓ Why all these web workers and why should I care?

Language services create web workers to compute heavy stuff outside of the UI thread. They cost hardly anything in terms of resource overhead and you shouldn't worry too much about them, as long as you get them to work (see above the cross-domain case).

❓ What is this loader.js? Can I use require.js?

It is an AMD loader that we use in VS Code. Yes.

❓ I see the warning "Could not create web worker". What should I do?

HTML5 does not allow pages loaded on file:// to create web workers. Please load the editor with a web server on http:// or https:// schemes.

❓ Is the editor supported in mobile browsers or mobile web app frameworks?

No.

❓ Why doesn't the editor support TextMate grammars?

• Please see https://github.com/bolinfest/monaco-tm which puts together monaco-editor, vscode-oniguruma and vscode-textmate to get TM grammar support in the editor.

❓ What about IE 11 support?

• The Monaco Editor no longer supports IE 11. The last version that was tested on IE 11 is 0.18.1.

定制内容

增加功能

• 支持 {{}} 表达式模式的代码校验

{{...}} 外为字符串，{{...}} 内是表达式，错误校验也只会校验 {{...}} 里面的错误信息

monaco.languages.typescript.typescriptDefaults.setDiagnosticsOptions({
	enableCurlyBracesExpressionMode: true
});

• 支持 {{}} 插值内个都是表达式的模式

它与 enableCurlyBracesExpressionMode 的区别是 {{...}} 内外都是表达式，且错误校验只会校验 {{...}} 外的表达式，{{...}} 内的表达式不校验

它们是互斥的，enableCurlyBracesExpressionMode 的优先级高于 enableCurlyBracesButIgnoreInnerError

monaco.languages.typescript.typescriptDefaults.setDiagnosticsOptions({
	enableCurlyBracesButIgnoreInnerError: true
});

• 增加获取当前光标前面的代码路径的方法 getRelevantCodePath

const model = editor.getModel();
const position = editor.getPosition();
const worker = await monaco.languages.typescript.getTypeScriptWorker();
const proxy = await worker(model.uri);
const offset = model.getOffsetAt(position);
const relevantCodePath = await proxy.getRelevantCodePath(model.uri.toString(), offset);
console.log('relevantCodePath', relevantCodePath);

• 增加获取当前光标所在代码的 AST Token 方法 getRelevantTokens

const model = editor.getModel();
const position = editor.getPosition();
const worker = await monaco.languages.typescript.getTypeScriptWorker();
const proxy = await worker(model.uri);
const offset = model.getOffsetAt(position);
const relevantTokens = await proxy.getRelevantTokens(model.uri.toString(), offset);
console.log('relevantTokens', relevantTokens ? JSON.parse(relevantTokens) : relevantTokens);
