shmalaga is a Galaga clone that I wrote for a class project. It is no
longer being maintained, but I think it’s interesting to consult for reference
purposes because it demonstrates how to use Haskell’s gloss library to create
an action game in a pure functional style. The methods gloss uses for
e.g. redrawing sprites and event handling are somewhat reminiscent of
functional reactive programming.
This software was originally built for Arch Linux and Mac OS X, but recently the Gloss library seems to have stopped working on Linux. See this discussion for details. However, the project still compiles and runs on OS X Mojave. The following are required to compile it:
- Glasgow Haskell compiler (8.6.4)
- Cabal build system
This project only requires cabal and ghc to be installed. Cabal will
automatically pull the latest version of the Gloss library from Hackage and
compile it as part of the build process, so no need to install it separately.
To compile shmalaga, run the following command in the root directory of the
project:
$ cabal new-build
To play the game, run it using cabal:
$ cabal new-exec shmalaga
The game will begin running in a separate window.
The source files are located in the root directory of the project:

- EnemyMoves.hs
- EventHandler.hs
