Question

imge of errror

I'm very new to haskell and the entire installation process was confusing to me. I downloaded power shell and then installed chocolatey and haskell. now im putting ghci into my command prompt and trying to run my.hs file.

Answer 1

In order to load a file, you should work with the :load (or its shortcut :l ) directive, so:

:load C:\Users\gravon\OneDrive\Desktop\yoo.hs

once you loaded the file, you can run a function, for example a main , given this function is defined in the yoo.hs .

You can also work with runhaskell [haskell.org] and thus run a file in the shell with:

$ runhaskell 'C:\Users\gravon\OneDrive\Desktop\yoo.hs'
