How to reset Codemirror Editor?

I would like to reset all the contents of the Codemirror editor. Ideally, this should clear the text box, remove all marks and clear the history.

What is the best way to achieve this?

cm.setValue(""); cm.clearHistory(); // cm.clearGutter("gutterId"); if you have gutters

If you don't want to kill an instance of CodeMirror, just change the entire document containing the text, marker data, etc.

This can be done by calling cm.swapDoc(doc: CodeMirror.Doc) .

In addition, executing cm.setValue(newValue) simply sets the contents of the editor without deleting the CM instance. Doc
