Per the (somewhat dated) Singular documentation @hannes14 (https://www.singular.uni-kl.de/index.php/graphical-interface.html), Singular can be used from a Jupyter notebook via @sebasguts's PySingular and jupyter-kernel-singular.

Here we add the single module providing the PySingular API into passagemath-singular, enabling use of jupyter-kernel-singular with it.

Declaring extras for easy installation, using one of:

$ pip install "passagemath-singular[jupyterkernel]"
$ pip install "passagemath-singular[notebook]"
$ pip install "passagemath-singular[jupyterlab]"

jupyter-kernel-singular does not work with Python 3.13

Traceback (most recent call last):
  File "<frozen runpy>", line 198, in _run_module_as_main

    import imghdr

This is one of the removed "dead batteries". Replacement: https://pypi.org/project/standard-imghdr/

@sebasguts Do you accept patches to this old project of yours, or would you be willing to add me (and/or others) to https://pypi.org/project/jupyter-kernel-singular/ to post updated releases?
