Thanks for the reply. What's the simplest path to getting this? I'm not very familiar with haskell tools, library management. I'm using ubuntu if that helps On Mon, Jan 5, 2015 at 2:25 PM, Carl Eyeinsky wrote:

Hi Dustin,

perhaps you're missing mtl. (There are also C.M.Trans.State in transformers, though IIRC you have to use lift there to access the methods in your monad stack.) On Jan 5, 2015 9:28 PM, "Dustin Lee" wrote:

From the homework description I've tried running:

dlee@morty ~/repos/cis194/week7 $ runhaskell StringBufEditor.hs

Editor.hs:11:8: Could not find module `Control.Monad.State' Perhaps you meant Control.Monad.ST (from base) Control.Monad.ST.Safe (from base) Control.Monad.Fix (from base) Use -v to see a list of the files searched for.

Is my haskell install messed up? Have the libraries changed since the homework was created?

Thanks,

dustin

You can see examples of how to use Cabal and sandboxes to install packages like mtl in an article I wrote for HowIStart: http://howistart.org/posts/haskell/1 People are getting steered toward minimal GHC installs on purpose. New people have to learn how to install packages anyway. You just have to show them and then they can handle it fine. --- Chris Allen On Mon, Jan 5, 2015 at 3:28 PM, Brandon Allbery wrote:

It sounds like you have a minimal ghc installation. Many things were shifted from ghc's minimal install to the Haskell Platform.
