Functional Software Architecture

You don't need to download and run code on your own computer, but it may be helpful to do so. In that case, you should make some preparations.

If there are problems with the setup, e-mail Mike Sperber.

Preparation

If you have a working Haskell/Cabal setup for ghc 8.8, things might just work. (ghc 8.10 will not work.)

Otherwise:

• install Docker
• give Docker at least 6GB RAM where relevant
• install Visual Studio Code
• install VS Code Extension "Remote - Containers"
• select "View" -> "Command Palette" (some modifiers + P), type "containers", select"Remote - Containers: Open Folder in Container"
• open the hearts directory

VS Code will then construct a container to do its business. That might also take while.

Starting the Game

Console

The Sync module has two functions gameAlong and gameInteractive. (Very rudimentary.)

UI version

• you'll need to comment out the buildable: False line

• in the hearts directory, run ./docker-shell.sh to start a suitable shell in a Docker container

• inside the Docker container, do cabal update && cabal build to build the server

• inside the Docker container, do ./run-server-inside-docker.sh to start the server

• outside the Docker container:

• install Elm

• cd to hearts-frontend, do:

elm reactor

• go to the URL there, typically http://localhost:8000

• click on examples, then HeartsFrontend.elm
