Member Presentations

Some presentations relevant to the course from years gone past:

Getting Started

Install Stack

This project uses Stack to build and test the assignments. To install it, follow the steps here.

Or, use Homebrew:

brew install haskell-stack

Clone the Repo (Don't Fork!!)

15:07 $ git clone [email protected]:laser/cis-194-summer-2018.git
Cloning into 'cis-194-summer-2018'...
remote: Counting objects: 350, done.
remote: Compressing objects: 100% (9/9), done.
remote: Total 350 (delta 13), reused 10 (delta 10), pack-reused 331
Receiving objects: 100% (350/350), 9.41 MiB | 2.93 MiB/s, done.
Resolving deltas: 100% (134/134), done.
Checking connectivity... done.

Create a Branch

Create a new branch off of master whose name is the same as your GitHub username. Then, push the branch to the remote (GitHub) repository. If you don't have permission to push to this repository, let me know and I'll grant them.

15:07 $ cd cis-194-summer-2018/

15:09 $ git checkout -b laser
Switched to a new branch 'laser'

15:09 $ git push origin laser
Total 0 (delta 0), reused 0 (delta 0)
To [email protected]:laser/cis-194-summer-2018.git
 * [new branch]      laser -> laser

Initialize Stack

We use Stack to build our project. After cloning the repository, run stack setup.

Running the Tests

Assignments are tested with Hspec and QuickCheck. The full test suite can be run by running the stack test command.

To run a single test:

15:10 $ stack build && stack runghc test/Homework/Week01Spec.hs

To rebuild and run the tests each time one of the project's files change:

15:13 $ stack test --file-watch

To rebuild the project and re-run a single test when a file changes, look into something like entr.
