CodeMirror 6 Code Evaluation

npm install @management/cm-evaluate

This package should be used with the stable release of the CodeMirror 6 packages (version 6.x.x). Using this with the beta versions of CodeMirror 6 will cause errors.

Basic Usage

import { EditorView, basicSetup } from "codemirror";
import { evaluation } from "@management/cm-evaluate";

// Define a function that handles evaluated code
function myEval({ evaluation: { code } }) {
  eval(code);
}

// Then, pass that into a codemirror instance
let view = new EditorView({
  extensions: [evaluation(myEval), basicSetup],
  parent: document.body,
});

By default, this creates two keyboard shortcuts:

• Shift+Enter: Evaluate the current line
• Ctrl+Enter (Cmd+Enter on Mac): Evaluate the current block of lines separated by blank lines
