[Haskell-beginners] Debugging in Haskell

[m00nlight]

Emacs can be configured to look great, see the following quora answer for example. You can just try to get used to it and
add your configuration incremently. After a few time, it will be of beautiful appearance.

             I did try to use Leksah, but did not like the interface. I don't    think it helped with debugging, but may be mistaken. I'm now using    sublime 3 and hoping that someday I will be able to use Atom. Emacs    appears to be the standard, but it is just too ugly for me.

That's interesting.
         
         I must confess that I find the need to debug in Haskell          greatly reduced because I tend to design stuff in small          incremental steps in ghci / emac in a Lisp like way which          means that I am reasoning out my code as I write it which          usually means there are no logical bugs at least.
       

       However I can see the need on occasion to maybe debug into        issues relating to threads / STM and behaviours between        processes in general.
       
       Have you tried using Leksah, the Haskell IDE?

         I need to            improve my Haskell debugging skills. I know of quickcheck,            but that's for testing. It seems that:
           
           - Debug.Trace and
           - dynamic breakpoints in GHCi
           
           Are the two easy ways to check the state of your program at            a specific point in execution.
           Is there another simple tool that I should know about? Any            tips?
           
           Thank you,
