Hi all,
I just tried the new GHCi debugger. A great new feature of GHCi 6.8.1.
When debugging a function, as for example the qsort function given as an example in the "3.5 The GHCi Debugger" documentation page, the debugger will only break on first function evaluation.
As haskell is pure and lazy it's probably a normal behavior (reuse last result instead of recompute) but it's not very practical in a debugger. I tried to reload (:r) but it doesn't seems to help. Is there a way to force the function to be re-evalutated without quitting, starting, loading prog and setting breakpoints again, other than making the function part of the IO monad. ;-)
Definitely, there should be one such way. Could you paste a ghci session demonstrating the problem? Thanks in advance, we are heavily in need of feedback and bug reports reg. the debugger. pepe
