Javascript shell?

I know that this question has already been asked HERE but sadly none of the answers suggest a javascript standalone shell that has auto completion. I am reopening this question again, in the hope that some new answers might be found.

From stackoverflow

• http://www.faqts.com/knowledge_base/view.phtml/aid/1438 lists some JavaScript interpreters. I am not about to download them to confirm they have (tab?) completion.

  [I'm not sure what you mean by auto-completion, since that implies more of an IDE-type approach].

  Is this for web-based development/debugging? If so, I can really recommend the squarefree JS shell bookmarklet for Firefox, which was listed in the linked post. True, it is not standalone, but does have tab completion.

• If you're looking at client side Javascript, have you looked at Firebug? It gives you command completion for the current window - including any pulled in libraries, etc?

  You can run it as a plugin from Firefox, or include it in any web pages for other browsers (not sure whether completion works with firebug lite)

• According to this blog post, autocompletion is now available for Rhino, as long as the JLine library is included.

  esiegel : Thanks, I'll give that go.

• Jash is a DHTML-based window that gives you command-line JavaScript access to the current browser window. With this console you can quickly run debug scripts. It has auto completion using the TAB key: http://www.billyreisinger.com/jash/

  Firebug is a Firefox extension with an advanced command-line. It also features auto completion in the single line mode. See the full command line API: http://getfirebug.com/commandline.html

  If you want a shell in you OS environment try Mozilla's Rhino Shell. This JavaScript shell provides a simple way to run scripts in batch mode or an interactive environment for exploratory programming.
