Vian

Welcome to Vian. Vian is a text editor written entirely in Javascript. To try it out, click on the editor pane with the cursor in it to give it keyboard focus. By default it acts like vi, but under the hood it looks a lot like Emacs. You can add major and minor modes easily by adding additional Javascript files, just like you would with emacs lisp. Vian also has a back end hosted on Google AppEngi
