The Pylint Plugin Proxy allows to define and distribute pylint astrioid transform and in future also likely type inference plugins with the python module they provide additional static knowledge for.
Add the path the Pylint Plugin Proxy module is stored to the PYTHON path envirionment variable. Activate the plugin on the commandline by calling
pylint --load-plugins=pylint_plugin_proxy <filetolint>.py
or set the correspoinding parameter in the pylintrc file accordingly.
Change to the directory where MyModule.py is stored and create the corresponding
MyModule.ast.py plugin module by typing
editor MyModule.ast.py
An example on how to write a transform plugin can be found on https://pylint.readthedocs.io/en/latest/how_tos/transform_plugins.html
The next time pylint is called using the above line MyModule.ast.py plugin module will be loaded and used when a class defined in MyModule.py is encountered by Pylint.
