Hi there,

I’m trying out Ruby on Rails for the first time. I want to know if  
there is a good debugger for it. Does anybody know of one?

Thanks

Hi,

at least you can start by using script/breakpointer and put “breakpoint”  
statement on your code. Then, when the breakpointer reacts to the  
breakpoint your can examine all the environment (local instances, class  
instances, and so on)

Honestly, I didn’t needed anything else until now

David-

```
Kent S. has recently made a quite nice debugger that you can

use on rails apps. Here’s his blog:
