Adding page meta to pages during on_file?

[Andre601]

Need help finding a possible fix for an issue I'm currently facing.

The issue is, that the categories plugin by EddyLuten is not picking up any categories enries added to the metadata of a page by the meta plugin from Squidfunk.
I've discussed this already with EddyLuten and the issue is, that the categories plugin pulls the metadata during the on_files phase, while the meta plugin adds theirs during the on_page_markdown phase, so after the categories plugin retrieved the metadata already.

While EddyLuten will try to find a fix, I in the mean time would like to see, if there's a workaround for this issue, even if it is "hacky"... Preferably using a hook that mimics the meta plugin's behaviour...

For clarity, the meta plugin allows you to add a .meta.yml (file name configurable) to your docs folders to apply metadata (frontmatter) to any pages and sub-pages in that directory.

I used it to add primary categories to multiple pages and I hope I can somehow redo/use this...
