EyeCatch Syntax Highlighter

One of the main issues when posting code on a blog is that it is very hard to read. Several javascript libraries have been made to solve this problem, and the most used one to date is Syntax Highlighter by Alex Gorbatchev.

My website is running on Umbraco and it uses TinyMCE v3 as text editor. Inspired by the old SyntaxHighlighter plugin by Nawaf Albadia I created a new and improved version that is compatible with the latest version of Syntax Highlighter (3.0.83).

I also created a version that is designed to run on Umbraco v4.7 and also leverages the power of Client Dependency Framework. This means that all the necessary stylesheets and javascripts are added and minified automatically. All you need to do is to add one line to your master template.


  1. Uninstall the installed version (otherwise TinyMCE.config will be messed up).
  2. Head over to the project page on our.umbraco.org and download the package there.
  3. Install it in the Developer section in Umbraco by clicking "Packages" -> "Install local package". Browse to the file you downloaded and click install.
  4. Then add the macro "EyeCatch Syntax Highlighter" to the <head /> section of the page you want syntax highlighting on. If you want to use a different theme than the default one, just specifiy the name in the "Theme" parameter. Otherwise leave blank.
    Note: This version of the package requires that jQuery is loaded on your page before the macro. In future versions this will not be needed.
  5. Open a content page with a richtext editor on it, and click the code icon to the right on the toolbar. Paste your code in the window that appears, choose the language and then optionally some settings.


  1. Go to a content page with the TinyMCE editor on it. Click the code button that has now appeared on the right side of the toolbar.
  2. Paste your code in the textarea, select the language and optionally set some settings.
  3. Press insert and then save your page.
Thats it! Simple eh?

You can also use a custom theme by uploading your css file to "/umbraco_client/tinymce3/plugins/syntaxhighlighter/styles/themes/" and specifying the file name (without .css) as the Theme parameter.
