Instance Method Details

#convert_script(el) ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Hook into the <script> tag conversion process so that we have a chance to generate :gist elements based on the src attribute of the tag.
