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. Dimitri On 09/04/15 02:03, emacstheviking wrote:

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?

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,

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. http://www.quora.com/How-can-I-go-from-good-to-great-in-Emacs --m00nlight 在2015年04月10 08时18分, "Dimitri DeFigueiredo"写道: I did try to use Leksah, but did not like the interface.
