Plugin system in Elixir

I don’t think this is what you’re after - but just in case - eplugin has a totally different approach to plugins.

There is a dedicated gen_server process that is responsible compiling the plugins and managing their particulars in ETS tables.

I didn’t know the library. It seems very nice to decoupling the code. However, I see lack of flow control for my use case, stop the processing for example. I could define several callbacks, before_action and after_action, where the plugins can stop the action but it feels complicated.

I just do plugins via gen_event, isn’t that the easiest and most built-in way?

Literally I just send an event at whatever hook points I want and let whatever is listening to them do whatever they want at that point.

gen_event has it’s share of problems that I fixed in an erlang replacement library long ago, like using monitors instead of links (gen_event predates monitors did you know? ). Does Elixir have a GenEvent that uses monitors? I’ve not actually checked, I just use my Erlang library in Elixir thus far… >.>

Same here, it is perfect to decouple the code but not to control the flow of the code.
