Updating the Games Catalog

This page covers the process for contributing to and updating Gambit’s Games Catalog. To do so, you will need to have the gambit GitHub repo cloned and be able to submit pull request via GitHub; you may wish to first review the contributor guidelines. You’ll also need to have a developer install of pygambit available in your Python environment, see Building the Python extension.

You can add games to the catalog saved in a valid representation format. Currently supported representations are:

• .efg for extensive form games

• .nfg for normal form games

Add new games

1. Create the game file:

   Use either pygambit, the Gambit CLI or GUI to create and save game in a valid representation format.

2. Add the game file:

   Create a new branch in the gambit repo. Add your new game file(s) inside the catalog dir and commit them.

3. Update the catalog:

   Reinstall the package to pick up the new game file(s) in the pygambit.catalog module. Then use the update.py script to update Gambit’s documentation & build files.

   pip install .
   python build_support/catalog/update.py --build
   

   Warning

   Running the script with the --build flag updates Makefile.am. If you moved games that were previously in contrib/games you’ll need to also manually remove those files from EXTRA_DIST.

4. Submit a pull request to GitHub with all changes.

   Warning

   Make sure you commit all changed files e.g. run git add --all before committing and pushing.
