Why must named functions be in a separate file in hugs?
In Haskell in 5 steps the factorial function is defined as follows: let fac n = if n == 0 then 1 else n * fac (n-1) But for hugs, it says that fac needs to be in fac.h. Can anyone explain why this is the case - missing the ability to define named functions seems like a massive limitation for an interpreter? ...
How can you change the path where Hugs98 (Haskell) looks for Module and Libraries?
I have installed Ubuntu as a virtual machine so I could use Hugs98. However, after installing I realised I couldn't use Data.Char and Data.Ratio modules. I had to load them manually with :load /usr/lib/etc . It seems this happens because the modules are not in the place where they should be. Can anyone please tell me how I can change the...
