How to do it...

1. Create a new project called hedis-trie with a simple stack template:

        stack new hedis-trie simple

2. Add a dependency on the hedis library in the build-depends sub-section of the executable section:

        executable hedis-trie
          hs-source-dirs:      src
          main-is:             Main.hs
          default-language:    Haskell2010
          build-depends:       base >= 4.7 && < 5
                             , hedis
                             , bytestring

3. Open src/Main.hs. We will be adding our source here.

4. Add the initial module declaration and import the required headers. Enable OverloadedStrings as we will be dealing with ByteString in this recipe:

 {-# LANGUAGE OverloadedStrings #-} module Main where import Prelude as P import Database.Redis import Data.ByteString.Char8 as B import Data.Char import Data.Monoid import Control.Monad ...
