codeworld-tasks

This library provides abstractions and functions for evaluating images created in the vector graphics domain CodeWorld. The interface is mostly used as part of a Haskell programming task type on our e-learning platform Autotool.

Documentation is available on GitHub Pages.

Running Tasks Offline

The package provides an executable test-task to replicate the grading process of Autotool in a terminal. This currently only works on Unix systems (OSX untested, but likely works), Microsoft Windows is not supported.

First, follow the usual Student workflow:

1. Copy a task from examples/tasks into the CodeWorld editor.
2. Work on the task until you think you've solved it.
3. Paste your solution back into the template.

Now to simulate the grading process:

1. Install the z3 theorem prover (sudo apt-get install libz3-dev or similar)
2. Install Haskell Stack
3. Optionally set an alias for stack run -w run.yaml
4. Execute stack run -w run.yaml <task name> <[submission|solution]> (solution loads a sample solution)

The submission will either be rejected or accepted and feedback be printed directly into the console. Running the stack command may take a while the first time, since a lot of dependencies will have to be installed.

Sample solutions for all tasks are provided in examples/solutions for reference.

Single Page Application (SPA)
