  1. Great plug-in!  Thank you for building it!

  2. Grea plugin, I love syntax highlighting

  3. There's an error in codemirror/plugin.js. Line 92 needs comma removed after "codeMirrorTheme".

  4. I have a bug when including this plugin

    We use CK in an Ajax enviroment, and we use the create and destroy function.... after 29 times, IE crashes 

    When we removed this plugin form a fresh CK 4.1 or 4.03 we had no more memory leak

    I contact the CKteam and the have confirmed the problem with your Plugin ~

    can you please provide a fix:

     

    here a sample code to replicate a user opening and closeing ck 40 times note plenty of time is given for create and destrpy to run

     


    <!DOCTYPE html>
    <html>
    <head>
        <meta charset="utf-8">
        <title></title></head>
    <body><a onclick="createEditor()">Reload editor in inf loop</a><br>
        reloaded: <span id="number">30</span> times<br>
        <textarea id="textarea"></textarea><script src="ckeditor/ckeditor.js"></script><script>var count = 0; function createEditor() { CKEDITOR.replace('textarea', { on: { instanceReady: function (evt) { count++; document.getElementById('number').innerHTML = count; setTimeout(function () { evt.editor.destroy(); setTimeout(function () { createEditor(); }, 500); }, 500); } } }) }</script></body></html>

    • should be fixed now, new version is online.

      • Thank you the new version fixed the problem !

         

        That was so quick Tks !

  5. I have a minor issue that I hope can be solved easily.  I am using this plugin on a WordPress site and I believe I have found a small bug.  The HTML formatter is adding a new line before and after inline tags.

    I can't post the pictures here.  You can see the original post on the CKEditor site (Your plugin page)

     

    The pictures show what is going on.  I am using 4.1.1 with the latest version of your plugin.

    Edit:  Just a quick question, is code mirror doing the reformatting or is ckeditor?  When I get a chance, I will fire it up in NetBeans and see if I can find the issue with the debugger.

    Any ideas?

    • Turn off autoformatting in the codemirror settings in the editor config

      config.codemirror : {
      autoFormatOnStart: false,
      autoFormatOnModeChange: false} 

  6. It is possible to release a version for CKEditor 4.2?

    In CKEditor 4.2 I can't see Icons, if I download a package with the builder.

    A PHP highlighting would be greatful

    Thank you!

    • Download the plugin manually from the Github page.

      The CKBuilder doesnt work it doesnt include all files. And i also can not upload new versions here because that is also broken.
