It’s not Ruby that you would need to learn, but Rails.
That’s a fine curiousity, but if what you want to do is write a Discourse plugin with AI, then the AI plugin doesn’t seem like the place to start. I’d want to work with an AI designed to develop code.
More than that, however, if you want to write a Discourse plugin, choose one that does something similar and change it. Cakeday doesn’t seem like an especially simple plugin, but if what you want is a plugin that puts an indicator by a user’s avatar or does something on a schedule, then it could be a good place to start.
It’s pretty complicated, though, it involves all of the following:
- adding data to the user serializer, so the front end has access to it
- running a job on a schedule
- creating a route that provides new information (Discourse Meta)
- using a plugin outlet to add information to a page
And that’s just the start.
