Ace isn't correctly highlighting R comments

[DeegC]

I'm using Ace to edit/display R code and it doesn't appear to be correctly highlighting comments; basically it ignores them. It looks like it's correctly highlighting other R constructs (like NaN) so I assume I've set it up correctly. Do you want me to open a bug somewhere?

The code I'm using to build the HTML is as follows (built using Sinatra):

<td valign="top" style="height: 400px; width: 700px">
    <input type='hidden'
           id='editorvalue'
           name='#{param_name}' />
  <div id="editor" style="height: 400px; width: 700px">#{CGI::escapeHTML(attrib.to_s)}</div>
  <script src="http://d1n0x3qji82z53.cloudfront.net/src-min-noconflict/ace.js" type="text/javascript" charset="utf-8"></script>
  <script>
      function change() {
          var field = document.getElementById("editorvalue");
          value = editor.getValue();
          field.value = value;
      }

      var editor = ace.edit("editor");
      var session = editor.session;
      session.setTabSize(4);
      session.setUseSoftTabs(true);
      session.setMode("ace/mode/javascript");
      session.on('change', change);
  </script>
</td>

to use r mode you need to use r mode, like this

session.setMode("ace/mode/r");// intead of javascript!
because NaN is higlighted in javascript as well

I had tried changing it to use "ace/mode/r" but I got no syntax highlighting at all. I was then assuming that Ace was automatically detecting the mode (which, now that I think about it, is dumb). I debugged this a little further and Chrome debug is telling me that I'm getting "access denied" when I try to hit http://d1n0x3qji82z53.cloudfront.net/src-min-noconflict/mode-r.js . Pulling that up in my browser returns:

<Error>
<Code>AccessDenied</Code>
<Message>Access Denied</Message>
<RequestId>15814FF6D8BFB635</RequestId>
<HostId>

</HostId>
</Error>

Is there something I'm doing that's wrong? Should I be using a different URL? If this isn't the appropriate area for resolving this tell me where to go.

Thanks

Ah, i see. Version on cloudfront is old and doesn't have, r mode. you can download https://github.com/ajaxorg/ace-builds/ and use ace.js from there
