Haskell for Imperative Programmers

This is repository has haskell code that was built by following the video series Haskell for Imperative Programmers.

It was originally coded entirely in REPL.IT which is an online virtual repl environment.

Since in order to complete the series the project requires the installation of external dependencies, the base replt.it template chosen was the Haskell-Cabal.

Check out the template details for instructions on how to run it.

Structure

Here's the general structure of the project highlighting the files and directories we are going to touch.

(Most files and directories generated by the scaffolding process from the template are ommited).

/
|-- Cabal-example.cabal # cabal configuration file
|                       # external dependencies, runtime flags
|
|-- Entrypoint.hs # program's Main entrypoint
|
|-- /src  # "lib" code of the program
    |
    |-- /Exercises  # solutions to the exercises proposed by the video series
    |
    |-- Utils.hs  # general utility (such as printing)

Template details

This template makes it easy for you to use Haskell with Cabal on Repl.it.

Setup

• Fork this repl
• Open the shell (control/cmd + K)
• Run cabal sandbox init
• Run cabal update
• Run cabal install --only-dependencies
• Hit the run button and see "Hello, Haskell"

Usage

• Your entrypoint is Main.hs
• Run is linked to cabal run, so just hitting run would work!
• To add a new dependency simply add it to Cabal-example.cabal
• To install dependencies make sure to open the shell (control/cmd + K) and run cabal update && cabal install --only-dependencies

That's it! This template has titlecase as a dependency just for the example.
