This is an experiment of porting Chess in Haskell. Elm and Haskell share a lot of syntax and language features so this was fairly straight forward. The Haskell code makes use of certain features not available in Elm, particularly monads and list comprehensions.
There are three implementations:
- Collage uses Graphics.Collage to draw to an HTML canvas and to handle input
- Element uses Graphics.Element to draw using HTML divs and Graphics.Input to handle input
- VirtualDom uses elm-html to using an HTML table and uses onClick events for input
You can try it out at http://mtak.github.io/chess-elm/. You can build the code
by running eg elm-make VirtualDom/Main.elm --output virtualdom.html and
finding the resulting file in your browser, or you can try it out using code
you can either run it out by launching elm-reactor and navigating to
http://localhost:8000/VirtualDom/Main.elm.
