Since making things looks really nice in XUL is really hard, I decided that I would build the UI in the current Firefox content window (sorry tbird etc, but I built a less shiny version of this into Mozmill trunk for all of you).

Some of the functionality that I decided was a top priority was some slightly abstracted access to the window mediator which I am calling ‘windows’, and is simply an array of all the different windows available in the whole browser. The other big one is dir(), I am constantly looking for a property in one of the many, many objects I am trying to access and now that is really easy.

All of that goodness combined with enough space to stick real code blocks and a full history (which you can access using the shift key and up/down arrows), I find myself pretty comfortable.

After installing the extension, you can simply press ‘meta (cmd on mac) + shift + s’ and you should be greeted with the following (toggling will show/hide the shell):

UPDATE: It was pointed out to me that on windows meta may not be bound, so I have updated both the extension and git, please try ‘alt+shift+ctrl+s’ or ‘ctrl+shift+s’ on windows/linux, (I am testing in a VM so it’s a bit strange. Sorry about the confusion!) 

Welcome to XUSH

To get started, you can type ‘help’ to see what is available to you.

Help Menu

Other available functionality includes a big chunk of the mozmill controller for driving user actions in the browser, as well as elementslib — which gives you all kinds of powerful features for looking up nodes in the browser.

ElementsLib

As I mentioned above, the windows helper can quickly give you an idea of what is open in the browser and let you directly access the objects in the windows[x] array.

Windows Helper

The nice big console gives you enough space (and using shift) you can do multiple line commands to actually execute code snippets:

Code Blocks

My next round of features will include some more helpers, including tab completion and any bug fixes I find, please let me know of any that you find!

If you would like to play with the source, I have it on github and have a python script that uses mozrunner to launch it in dev mode (with venkman installed, although now I don’t really need it), but saves you from installing and uninstalling the extension every-time you want to try out your latest code changes:

python xush.py


That should launch Firefox with XUSH and Venkman both installed and allow you to hit the shortcut and wham, test away.

After another round of bug fixes I will be submitting this to Mozilla AMO.

Other projects you might be into if this interests you:

• Venkman
• Mozmill
• Chomebug

Thanks for your interest!
