Show CoffeeScript Lint on Codemirror

Question

I was playing with CoffeeScript earlier on Codemirror and I don't know why but linting is not working with Codemirror. Even the lint that's provided with the Codemirror package is not working for me.

What am I doing wrong and how can I solve this problem?

 // Initialize CodeMirror editor var editor = CodeMirror.fromTextArea(document.getElementById("code"), { mode: "text/x-coffeescript", tabMode: "indent", styleActiveLine: true, lineNumbers: true, lineWrapping: true, autoCloseTags: true, foldGutter: true, dragDrop: true, lint: true, gutters: ["CodeMirror-lint-markers", "CodeMirror-linenumbers", "CodeMirror-foldgutter"] }) 

 .CodeMirror { width: 100%; height: auto; }

Haha funny mistake. I forgot to add lint.js .

<script src="http://codemirror.net/addon/lint/lint.js"></script>

A quick note for anyone using this. I tried refreshing the lint with editor.refresh() to refresh the CodeMirror instance to get CoffeeScript lints instead of JavaScript lints in my editor, but the only way I could get it to work was disabling lints and re-enabling with...

editor.setOption("lint", false)
editor.setOption("lint", true)

Here's the snippet!

 // Initialize CodeMirror editor var editor = CodeMirror.fromTextArea(document.getElementById("code"), { mode: "text/x-coffeescript", tabMode: "indent", styleActiveLine: true, lineNumbers: true, lineWrapping: true, autoCloseTags: true, foldGutter: true, dragDrop: true, lint: true, gutters: ["CodeMirror-lint-markers", "CodeMirror-linenumbers", "CodeMirror-foldgutter"] }) 

 .CodeMirror { width: 100%; height: auto; }
