Rails 2.0 :: Debugger

To tie it all together, we have a stream of improvements for Rails in general. My favorite amongst these is the return of the breakpoint in form of the debugger. It’s a real debugger too, not just an IRB dump. You can step back and forth, list your current position, and much more. It’s all coming from the gracious note of the ruby-debug gem. So you’ll have to install that for the new debugger to work.

To use the debugger, you just install the gem, put “debugger” somewhere in your application, and then start the server with —debugger or -u. When the code executes the debugger command, you’ll have it available straight in the terminal running the server. No need for script/breakpointer or anything else. You can use the debugger in your tests too.
