Time and time again I find the need to terminate evaluation of an erb file on a certain line for debugging purposes, but can’t figure out a way to do it. Is this possible? Thanks! John ---

You need breakpointer. You’ll need to start the breakpointer utility in another terminal: ./script/breakpointer Now you can put the function breakpoint() anywhere in your controllers and I think in erb as well. The server will halt execution at the breakpoint, and the terminal that’s running breakpointer will put you into a ruby console where you can inspect variables modify values, etc. Type CTRL-D to resume.

Consider a page that does some dynamic actions in which you’re getting a nil exception, but you’re not sure why. You’d like to lump a few .inspect calls at the top of the file and then end processing there, but it doesn’t seem this is possible. I feel this would be an extremely useful feature… Thanks for the suggestions regardless! John
