Emmet plugin for CodeMirror online editor

Primary LanguageJavaScript

Deprecated: use codemirror-plugin instead with upcoming Emmet 2.0


Emmet plugin for CodeMirror 4.x+

To add Emmet support for CodeMirror editor, simply add dist/emmet.js as a <script> tag into your HTML page right after CodeMirror script. This script creates global emmetCodeMirror function but also can be loaded as Require.JS module. You should pass CodeMirror editor instance to emmetCodeMirror() to add Emmet support.

var editor = CodeMirror.fromTextArea(document.getElementById("code"), {
	mode : 'text/html',
	
	// define Emmet output profile
	profile: 'xhtml'
});
emmetCodeMirror(editor);

Available profiles are: html, xhtml, xml, but you can create your own output profile with emmetCodeMirror.emmet.loadProfiles({name: options}).

See profile.js for a list of available options.

Overriding keybindings

The emmetCodeMirror() function simply adds default Emmet action keybindings to editor instance. If you want your own keybindings or disable some of them, simply pass keymap (object) as second argument to emmetCodeMirror() method:

emmetCodeMirror(editor, {
    'Tab': 'emmet.expand_abbreviation_with_tab',
    'Cmd-Alt-B': 'emmet.balance_outward'
});

See defaultKeymap for available actions. The default keymap is exposed as emmetCodeMirror.defaultKeymap property.

NB: The Cmd key will be automatically replaced with Ctrl on non-OSX platforms.
