So I'm new to Python and the Calibre API (but not programming) and was trying to muddle my way through figuring both out by updating an old plugin for v5. Starting to think just redoing the pieces I need for now might be easier. To do this I was starting at the basics with the stuff at
https://manual.calibre-ebook.com/creating_plugins.html but the very basic plugin that should update the publisher to "hello world" is not even working. It shows the plugin loaded but importing a new epub does not add the publisher when there is none in the original metadata or when there is a publisher on the book it loads the one on the epub. Since I'm trying to do a plugin that will be manipulating/adding metadata for m4b files this example looked like a good start. Can anyone give me an idea of why? Does it need to be updated for v5? TIA.
