I'm pretty new in Haskell, few days since I started learning it. I want to debu my programs. I'm currently using WinHugs, and I prefer debugger for this. I tried googling and I found Hugs.Observer. I like it how it works, but still I have one BIG problem with it. It doesn't work well with floats. Following example import Hugs.Observe ex8 :: [Float] ex8 = (observe "after reverse" ) reverse [10.0,7.0,3.0,0.0,4.0] gives me
ex8 [4.0,0.0,3.0,7.0,10.0]
> Observations <<<<<<
after reverse { \ ($-990871 : $-990888 : $-990905 : $-990922 : $-990939 : []) -> $-990939 : $-990922 : $-990905 : $-990888 : $-990871 : [] } Which is not useful. After that I try to install http://www.haskell.org/hat/ but for installing that I need hmake, and when I try to install hmake, I typed first configure -prefix, and then, make. cd src/hmake; make HC=ghc BUILDCOMP=ghc all config make[1]: Entering directory `/cygdrive/E/Haskell/hmake/src/hmake' Makefile:59: *** target pattern contains no `%'. Stop. make[1]: Leaving directory `/cygdrive/E/Haskell/hmake/src/hmake' make: *** [targets/ix86-CYGWIN_NT-5.1/hmake-ghc] Error 2 as you can see I'm using cygwin. I'm really stacked here, and I will kindly ask for help.
