[TxMt] Ruby On Rails Stack Trace in TextMate like when starting a Ruby Script?

Hi,

I just discovered the coolness of Running a Ruby script from within Textmate. The unreadable Stack trace suddenly is readable and has amazingly cool hyperlinks to the exact line. I once saw in a Railscasts episode a Rails Bundle allowing to have such hyperlinks in the browser, but I could never keep up with which version and it broke all my other environment.

Any recommendation / direction for something as cool as the stack trace of a simple ruby file.

At the same time let me ask you how I could have a "debugger" in ruby (on or sans rails) or javascript could break into textmate.

Cheers, and hello, since this is is my first post here.
