This was super helpful, thanks!

I've found I can shorten it to:

.directive 'richTextEditor', ->
  return {
    restrict: 'A'
    replace: true
    require: '?ngModel'
    transclude: true
    template: '<div><textarea></textarea></div>' # Wrapper <div> required.
    link: (scope, element, attrs, controller) ->
      textarea = element.find('textarea').wysihtml5(
        stylesheets: null # Prevents a console error, likely a bug.
      )
      editor = textarea.data('wysihtml5').editor

      # Sync view -> model (took me 2 hours to figure this out)
      editor.on 'change', ->
        controller.$setViewValue editor.getValue()

      # Sync model -> view
      scope.$watch attrs.ngModel, (newValue, oldValue) ->
        textarea.html(newValue)
        editor.setValue newValue
  }

Just what I needed!

Thanks for the snippets! Works great. @statico I had another part of my page that was displaying the model's data so I added scope.$apply in the change listener for it to update the view.

Thanks a lot! that helped :)
@statico -

stylesheets: null # Prevents a console error, likely a bug.

its the path to wysiwyg-color.css on your server if the default ./lib/wysiwyg-color.css does not work for you

Now i have written the following code for data-bound bootstrap-wysihtml5. Seems to be working fine. I see the following issues.

1. the content change is reflected only on change. that is fired only on blur. can we use keyup and paste events somehow?
2. mine is a single page app with multiple editors in same page. when i try to change order of editors the content goes missing :( on refresh though the content is back. there is no error message on console. anyone faced this issue?
3. on trying to remove the editor from dom you get an error message. the editor tries to keep the div & textarea in sync which breaks because it isnt there anymore. anyone tried fixing this?

app.directive('richTextEditor', function() {
    return {
        restrict : "A",
        require : 'ngModel',
        replace : true,
        transclude : true,
        template : "<div><textarea></textarea></div>",
        link : function(scope, element, attrs, ctrl) {
            var textarea = $(element.find('textarea')).wysihtml5();
            var editor = textarea.data('wysihtml5').editor;

            // view -> model
            editor.on('change', function() {
                scope.$apply(function() {
                    ctrl.$setViewValue(editor.getValue());
                });
            });

            // model -> view
            ctrl.$render = function() {
                textarea.html(ctrl.$viewValue);
                editor.setValue(ctrl.$viewValue);
            };

            /* - similar to above
            scope.$watch(attrs.ngModel, function(newValue, oldValue) {
                textarea.html(newValue);
                editor.setValue(newValue);
            });
            */

            // load init value from DOM
            ctrl.$render();
        }
    };
});

I can't seem to get this working, here is my plunk! http://plnkr.co/edit/ezzDZy190ozvN1TQUt2d

activate the html mode then change to it and you will see that all the content in the attached model is lost.. it's back again after you exit the html mode and write something in the textarea

This version works with the HTML mode.

App.directive('richTextEditor', function() {
    return {
        restrict : "A",
        require : 'ngModel',
        //replace : true,
        transclude : true,
        //template : '<div><textarea></textarea></div>',
        link : function(scope, element, attrs, ctrl) {

          var textarea = element.wysihtml5({"html": true});

          var editor = textarea.data('wysihtml5').editor;

          // view -> model
          editor.on('change', function() {
              if(editor.getValue())
              scope.$apply(function() {
                  ctrl.$setViewValue(editor.getValue());
              });
          });

          // model -> view
          ctrl.$render = function() {
            textarea.html(ctrl.$viewValue);
            editor.setValue(ctrl.$viewValue);
          };

          ctrl.$render();
        }
    };
});

<textarea rich-text-editor ng-model="data"></textarea>

Really great stuff! Is it possible to prevent user to paste rich html ? I would like on paste to get only plain text inside editor.

@NenadP - I have the same problem with similar directive - the users paste from Word and everything stops working.

@joshkurz, what about Serv injection in the MainCtrl? I don't see any provider code...

Templates text style making problem , the hash tag redirect the root url ("<a class='btn dropdown-toggle' data-toggle='dropdown' href='#'>" ) please share a solution
