CodeMirror is a JavaScript component that provides a code editor in the browser. When a mode is available for the language you are coding in, it will color your code, and optionally help with indentation. A rich programming API and a CSS theming system are available for customizing CodeMirror to fit your application, and extending it with new functionality. This is the complete package available from http://codemirror.net.
