I read some Elixir books and I did some small toy projects with Elixir. My mind is still too object oriented programming but I want to start creating “real code”, specifically, I’d like to create shrinerb in Elixir. It is an awesome library that I use in Ruby and I think it could be cool to learn some Elixir.
My question is about the integrated plugin system. The author explained it very well in this blog post Briefly, it consists some base classes with a few methods which do very little. Then the plugins overwrite those methods adding some functionality and calling super, this way they don’t conflict each other. The user can select the plugins he needs and only those plugins are loaded. I think it is very elegant.
I don’t find a way to translate this to Elixir. The only solution I can think it is to create a “middleware engine” for each method of each class, so the plugins can inject their code safely. Two ways to do this are creating something similar to Tesla middleware or using defoverridable. However, I actually see this an overkill task. I don’t have enough experience to determinate if they are Elixir-ish solutions.
What do you think? Are good solutions? Or am I translating OOP to a functional language and it does not fit? In this case, what would be your solution?
Thank you very much for your time
