About

This is an EditorJs wrapper for CodeCup - A lovely lightweight zero-dep code formatter

It was built to be an improvement on :

• https://github.com/editor-js/code - Too Basic
• https://github.com/dev-juju/codebox - Agressive styling, and exports more data than markdown can handle

Demo

Built with:

• CodeCup
• Prism

Installation / Use

import EditorJS from '@editorjs/editorjs';
import editorjsCodecup from '@calumk/editorjs-codecup';

var editor = new EditorJS({
  // ...
  tools: {
    ...
    code : editorjsCodecup
  },
});

Language Selection

The plugin provides two ways to handle language selection:

• Free-form Language Input: By default (when no languages are configured), users can enter any valid Prism.js language key through a text input.

• Predefined Language Dropdown: When you provide a languages configuration, users can select from a predefined list of languages through a dropdown menu.

You can configure the language selection behavior using these options:

Predefined Languages

Provide a custom mapping of Prism.js language keys to their display names:

var editor = new EditorJS({
  // ...
  tools: {
    code: {
      class: editorJsCodeCup,
      config: {
        languages: { 
          javascript: "JavaScript",
          python: "Python",
          java: "Java",
          cpp: "C++",
          csharp: "C#",
          go: "Go",
          none: "Plain Text",
        }
      } 
    }
  },
});

Force Show Language Input

If you want to allow both predefined language selection AND free-form language input, use the forceShowLanguageInput option:

var editor = new EditorJS({
  // ...
  tools: {
    code: {
      class: editorJsCodeCup,
      config: {
        languages: { 
          javascript: "JavaScript",
          python: "Python",
          // ... other languages
        },
        forceShowLanguageInput: true // Shows both dropdown and language input
      } 
    }
  },
});

Refer to Prism.js supported languages for the available language mappings.

Data Format

The data imported/exported from the block is as follows:

Name	Description
code	The code that is displayed in the editor, with line breaks
language (optional)	The programming language
showlinenumbers (optional)	Will show/hide the line numbers (Default true)
showCopyButton (optional)	Will show/hide the copy button (Default true)

Since language and linenumbers are optional, existing code blocks can safley use this plugin
