This repository contains the calculations engine behind the ShadowCraft theorycrafting webapp for the Rogue class in World of Warcraft. For the web application including the UI see shadowcraft-ui.

ShadowCraft-Engine is written in Python and supports both Python 2 and 3. The calculation modules can be found in shadowcraft/calcs. Objects used for those calculations are defined in shadowcraft/objects.

How To

In order to support both Python 2 and 3, ShadowCraft-Engine depends on the future library. You can install it by running:

pip install future

To run a simple calculation for the rogue spec of your choice you can look at the examples in the scripts folder. Feel free to play around and edit those files as you see fit, when testing. E.g. to run a DPS calculation for Subtlety, type:

python scripts/


Although the tests currently do not provide good number testing for the different specialization models, they can be used to ensure that nothing major is broken. Run the tests using the following command:

python tests/

Of course, we appreciate any help in extending the test coverage for the engine.


The ShadowCraft team is always looking for help. If you would like to contribute to the engine, you can always contact the active developers or open a pull request on GitHub. There is also a #shadowcraft channel on the Ravenholdt Discord Server that can be used for discussion about the project.
