Debug Repl — debugging clojure code
Lets first make sure we need a debugging tool. I for one believe (addicted) to test driven development. I should not say believe, in fact my mind works better when I write tests. Writing tests force to me to think all different scenarios code could be executed and what should be the outcome. So I have good test coverage and it is easy to debug my code when a test fail. As I will know exactly where the problem is. But when I am running my code in context of some environment it is difficult to find issues. That is when I use poor man’s debugging tool (yes I am talking about println) and try to find what is causing issue. So there is a need for a debugging tool …
My friend and colleague George introduced to me to debug-repl. In fact he wrote it. It is so simple to use. Include
where you want debug repl to start. When you run code, debug repl will stop the execution of code and will start a repl. Now you are free to see what values are set etc.

Happy debugging … (but write tests … no excuses)
