The type hinting introduced by PR #755 is broken. By inspection of the stub files
*.pyiit appears that the utility toolstubgenfrom themypypackage is producing garbage for modules generated by Cython .This PR replaces the usage of
stubgenby a new Python scriptpyxstubgen.pythat parsesjsbsim.pyxto find all the classes, methods and functions declarations with their type hints and then generates a proper stub file_jsbsim.pyi.Since parsing a Cython file is no trivial job, the script
pystubgen.pyis using the lark parser (a parser toolkit fully written in Python). A grammar filecython.larkhas been created for that purpose. It is the minimum grammar that works for the JSBSim cython code and is by no means pretending to be able to read any cython file.This PR is addressing some proverbial itch scratching: I am annoyed that my favorite IDE does not autocomplete the classes and functions from the JSBSim Python module. I have run some tests that confirm that autocomplete works when the Python module is generated using the new script
pyxstubgen.py.Please note that this feature is meant to be used by our CI workflow when building the packages that will uploaded to PyPI. It is not part of the standard development cycle (i.e. write code/build/tests) so developers do not need to install
larkon their systems.
