For more details about ruby-debug, see my write up about it.
The command line is great, and there are times when you are working on a remote server where nothing else will do. But having the ability to set breakpoints at the click of the mouse, see your variables in a separate pane, see a lot more of your source code is something quite convenient.
And with the added speed of ruby-debug, this should make debugging in Rad Rails something you can’t afford not to use.
This is very welcome news and I look forward to use it!
