This is also the main debugging feature I want and don't have in any of the ways that I currently work with Clojure. I've seen montion of libraries that one can include that will give one this kind of functionality, but I've never gotten anything to work. Does anyone know a simple way to do this that doesn't involve an Emacs-based tool set? In my former life in Common Lisp I think that every environment -- from command-line-based implementations to full-featured IDEs -- would put you in a REPL at the point of an error, from which you could examine locals all the way up the stack, evaluate expressions, and even redefine things and continue. I don't usually need all of this, but it seems cruel for the system to be throwing away all of that stack info (local variables) that I often know contains the information I need to track down and fix a bug.

So it sure would be nice to be able to see the locals that were in play when the error was triggered! -Lee -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
