Francy is a framework for Interactive Discrete Mathematics built for GAP - Groups, Algorithms, Programming - a System for Computational Discrete Algebra.
Unlike XGAP, Francy is not linked with any GUI framework and instead, this package generates a semantic model of data structures that can be used to produce a graphical representation of these, using any other framework / language.
We provide a Javascript module able to produce graphical representations of the semantic model, that works on Jupyter environments, embedded in a Web page or as a Desktop Application (e.g. using electron).

In order to use this module in JupyterLab and Notebook >=7.0.0, install it as follows:
mcmartins@local:~$ pip install -U jupyterlab-francyIf you still use the old Jupyter Notebook (<7.0.0), you should use the old extension v1.2.4:
mcmartins@local:~$ pip install -U jupyter-francyPlease note that in order to use Francy, it is required that the JupyterKernel GAP package is installed.
See Jupyter GAP Kernel for more information.

All developments should happen on the branch develop and this should be merged into master when one is happy to release.
To release, the official ReleaseTools procedure should be followed.
To update the JS packages version, run the following command and pick the new version:
user@local js/ $ yarn run versionTo update the Python3 package version, please change it on the pyproject.toml:
js/packages/francy-extension-jupyterlab/pypproject.toml
To update the GAP package version, please change it on the PackageInfo.g file:
PackageInfo.g
There are 2 workflows defined for this project:
- CI - This workflow runs all tests (JS and GAP) for every commit/pull request on branches
developandmaster - RELEASE - This workflow runs the Python PyPi.org and NPM releases on new
tags created, normally after running the ReleaseTools procedure.
