Parley

Par·ley n.

To have a discussion, especially with an enemy.

Parley is a web application for storing and retrieving comments. It is an educational example whose primary goal is to demonstrate the application of beginner Haskell concepts in a real project.

Building and running

To build parley, run the following from the root of the project:

$ cabal install --only-dependencies
$ cabal configure --enable-tests
$ cabal build

Once parley has been built successfully, you may run it thusly:

$ cabal run parley
$ # OR
$ ./dist/build/parley/parley

...and with command line options

$ cabal run parley -- --port=8888
$ # OR
$ ./dist/build/parley/parley --port=8888

Finally, if you're using GHCi, you can run the application from there and pass command line arguments as well.

λ> :main --port=8888

Troubleshooting

You may need to install the zlib1g-dev package on Ubuntu before you can install dependencies.

$ sudo apt-get install zlib1g-dev
$ cabal install --only-dependencies
