Wow, awesome!

Sorry to comment on an ancient post, but for future reference: I got an error number -2741. After a little research it became apparent that tell atab to do javascript "window.location.reload()" should read tell atab to execute javascript "window.location.reload()".

Also, I needed to enable Chrome to execute Javascript events throught AppleScript (View -> Developer).

This looks awesome, but I'm not able to get the rb-script nor the service working in Lion. Any ideas?

Awesomely awesome! Thanks for saving some very repetitive keystrokes.
Though, I only managed to get it going in Safari (the system service version) but when I run the Crome version I, when I change one of the files inside the watched folder I get:
The action “Run Shell Script” encountered an error.

Thanks. This is very useful. I'm enjoying working through my test process using this.

A quick word though. The Watcher Automator script does not seem to work on Lion.

You wouldn't happen to have a version running on Lion, would you?

One of these processes got away from me today. Seems like using the services menu they will persist. I just stopped the service but the process (ps x | grep ruby) is still showing up.
