title: Eclipse: associate an editor with a content type
body: <p>Can I change editor associations based on the content type rather than individual file types?</p>
  
  <p>If I go to <code>Window -&gt; Preferences -&gt; General -&gt; Editors -&gt; File Associations</code>, I see a list of file types based on the file extension.</p>
  
  <p>Clicking on "*.py" for example, the Associated Editors box lists editors that are "locked by 'Python File' content type".</p>
  
  <p>I can see the message at the top that says I can "See 'Content Types' for content-type based associations", but that section of the preferences (General -> Content Types) only shows file extensions associated with the content types, not editors.</p>
  
  <p>Since the hierarchy of content types is organized in a way that most files are under the "Text" content type, one of the things I'd like to do is add gvim as an external editor available for Text/* files rather than go to each file type individually and add the editor.</p>
  
  <p>Thank you.</p>
