Thanks. I’m on mobile now and I don’t even know if I have access to submit updates to the wiki, but I’ll try when I’m at a computer if fox doesn’t fix it first (which he probably will).
My other comment was tongue-in-cheek, but honestly if you’ve done PHP coding just take a look at the plugins bundled in the core, it’s pretty straightforward. For each “hook” TT-RSS passes a value to registered plugins for that hook. Your plugin returns the result. Multiple plugins on the same hook are called in sequence. Your plugin just needs to be wrapped in the correct class with minimum methods for verifying API version, etc.
Take a look and reply with questions if you have any.
