Obsidian Code Emitter

This plugin allows code blocks executed interactively like jupyter notebooks. It is based on HTTP REST APIs and JS sandbox and Webassembly technology, and has no local environment requirements, so it supports all platforms supported by Obsidian.

Supports all Obsidian supported platforms, includes:

• Windows
• MacOS
• Linux
• Android
• IOS

Currently, support languages:

Supported language	Way
Rust	https://play.rust-lang.org
Kotlin	https://play.kotlinlang.org
V	https://play.vosca.dev/
JavaScript	JS Sandbox (qiankun)
TypeScript[]	TypeScript Compiler + JS Sandbox
Wenyan	Wenyan Compiler + JS Sandbox
Python	WebAssembly (Pyodide)
Java	Sololearn
Go	Sololearn
c/c++	Sololearn
CSharp	Sololearn
Swift	Sololearn
R	Sololearn

Note: Only Python、TypeScript、JavaScript are run locally in sandbox(js / webassembly). Other's will send code to third-party website to eval the results (eg: https://play.kotlinlang.org, https://play.rust-lang.org). Please take care to avoid sending your potentially-sensitive source code.

Any languages that support CORS

Here is the example to support Ruby.

const runCode = async (code: string, lang: 'cpp' | 'go' | 'c' | 'java' | 'cs' | 'swift' | 'rb') => {
  const header = {
    'User-Agent': 'Obsidian Code Emitter/0.1.0 (If this is not allowed, please let me know)',

  };
		
  const res = await fetch(url, {
    'headers': header,
    'body': JSON.stringify({
      'code': code,
      'codeId': null,
      'input': '',
      'language': lang
    }),
    'method': 'POST',
  });
  return (await res.json()) as {
    success: boolean,
    errors: string[],
    data: {
      sourceCode: number,
      status: number,
      errorCode: number,
      output: string,

console.log((await runCode(ruby_code, 'rb')).data.output);
