title: Relationship between Eclipse, Aptana, PyDev, and LiClipse
body: <p>I've been going nowhere but in circles trying to understand the odd relationships between and varying levels of "standalone-ness" of these tools.</p>
  
  <p>I've been using Aptana Studio on OSX for about 4 years and been happy with it, however my recent update to 3.6 blew up so many things I ended up rolling back to 3.4 just so I could work.</p>
  
  <p>For better or worse, I do like Aptana, but I'm not bound to it and am now very frustrated with the latest version, specifically that all the python stuff went haywire.  Searching for help is painful, as threads and advice are many years old.</p>
  
  <p>So, in way of questions: </p>
  
  <ul>
  <li>can anyone explain the relationship between Eclipse, Aptana, PyDev, and LiClipse? And more importantly:</li>
  <li>a recommendation that meets the following criteria</li>
  </ul>
  
  <p>What I need/want is: </p>
  
  <ul>
  <li>something free and open source</li>
  <li>with a current and active community</li>
  <li><em>easily</em> themeable with dark colors so I'm not staring at the sun 8 hours a day</li>
  <li>tight python features (pep, pylint, ability to jump to references with a keypress, etc)</li>
  <li>tight html/css/javascript features</li>
  </ul>
  
  <p>Like I said, I do like Aptana, just frustrated in the apparent lack of a current community and how it seems to be falling apart.</p>
