dragonfly, debugging
Two tutorials on using Opera Dragonfly (and other debuggers) by yours truly are out:
debugging DOM issues on thinkvitamin.com and the brand new
advanced JavaScript debugging on A List Apart. Hope you'll find them worth reading.

dragonfly, user javascript, debugging
The web is full of scripts that are "compressed" with all whitespace removed to make them download faster. Such scripts are hard to debug..
Here is a small user JavaScript which re-formats script source code to make those "compressed" files simpler to debug with
Opera DragonflyDownload User Javascript..Note: this script is converted from PHP in a quick and messy way - apologies for any PHPisms, and for the variables that are still prefixed with a dollar sign. I've been using it for a while but I still find bugs and scripts that the formatter can not handle, so be prepared that there may still be some work to do.. Let's call it an alpha release

dragonfly, developer tools
Dragonfly blog has details and download links.
dev.opera.com has technical details and tutorials.
Now, this is an alpha release. Some issues you may have to overlook gracefully include:
- If you enable breaking on every script, the debugger will also break when Opera runs browser.js or user scripts - but no code will appear in the code pane! You will have to click "run" one or more times to get past your user scripts.
- It only responds every second time you press [F10]..
- Live CSS editing is missing..
- ..and so is HTTP logging and some other nice features that will arrive later.
That said, Dragonfly is already making itself useful in its present form. Have fun with it!
