CodeMirror custom showHint() call doesn't work

Question

Attempting to implement a custom showHint call for a spellcheck module. I've followed the docs but calling editor.showHint appears to do nothing and returns undefined.

I figure there is something I am missing. Here is my sandbox code to test:

editor.on('cursorActivity', function() {
    var options = {
    from: editor.getDoc().getCursor(),
    to: editor.getDoc().getCursor(),
    list: ['foo', 'bar', 'baz']
  };
  editor.showHint(options);
});

OK, figured out my problem, per the docs:

Finding hints is done with a hinting functions (the hint option), which is a function that take an editor instance and options object, and return a {list, from, to} object

Instead of passing from, to, and list into showHint(options), they must be returned from a hint function passed into showHint.

editor.on('cursorActivity', function() {
  var options = {
    hint: function() {
      return {
        from: editor.getDoc().getCursor(),
          to: editor.getDoc().getCursor(),
        list: ['foo', 'bar']
      }
    }
  };
  editor.showHint(options);
});
