Re: [Haskell-cafe] CIS 194 not compiling under new GHC

This being a beginners course, it would still be better if it were kept up to date with such changes instead of requiring newcomers to know about them. Byorgey? On Sun, Nov 6, 2022 at 12:42 PM David Feuer wrote:

The changes needed to make it work should be minor. Since you call out the chapter on monoids, any Monoid instance now needs a Semigroup instance.

Before:

instance Monoid X where mappend a b = ... mempty = ...

Now:

instance Semigroup X where a <> b = ... instance Monoid X where -- mappend no longer needs to be defined mempty = ...

Hi all,

I've been working through the CIS 194 course recently and unfortunately from lecture 7 onwards the code is not compliant with current compiler.

I can still follow the lectures but I'd like to do every homework exercise. Unfortunately most homework exercises provide you with a code framework to work with and this code does not compile.

Do any of you know about updated versions or corrections to this course? I believe there could be a repo where someone is keeping the course's homework up to date because this course is still quite popular.
