Antlr4 Editor

Overview

The goal of this project/library is to provide developers with a simple to use API to develop web compatible code editors, using only Antlr4 Grammars. Allowing for the creation of the editor and language to be more unified during the development process.

(Currently the only fully supported editor platform is codemirror at the moment)

Getting Started

npm install -S antlr4-editor

Example Generating An Editor

Generate the source files for creating a C Editor.

antlr4-editor -o src/editor -r compilationUnit samples/c/C.g4

Example Output

Run the Test Editor Application

node ./src/editor/test-editor-app.js

Javascript Code of a Simple C Editor

Given that you've generated editor source code, the following code creates a simple C language code editor.

const createEditor = require('./editor').createEditor;

const editor = createEditor();
editor.setEditorPlaceholderText('Enter your code here...');

editor.setShowLineNumbers(true);
editor.setDisplayEditorErrors(true);
editor.focus();

const el = editor.getDomElement();

// Render the editor
document.body.appendChild(el);
