Question

I want to shaffle string characters and I have found ‘shuffle’ function in Data.Random.Extras. But when I am trying to import it I get the error message:

*Main> import Data.Random

<no location info>:
    Could not find module `Data.Random':
      Use -v to see a list of the files searched for.

How can I import this package? Or maybe there are another way to shuffle string characters?

Answer 1

This package doesn’t come with Haskell and needs to be installed.

Have you used cabal before? You can install new packages with

cabal install random-extras
