I am getting more and more used to writing things in Elixir. However, when trying to create intermediate applications that use multiple processes, my years of working with Object-Oriented Programming languages kick in, wanting to create processes that re-use some of the logic of other processes. In …

You should probably look into Elixir Protocols. Extensible Design with Protocols I wrote some code this week that reinforced the power of protocols as a tool for software design. The term “protocol” can mean many things in the world of software. Let me clarify that I’m using protocol t…

To clarify: I totally understand that processes are not the same thing as objects from an OOP-language. (Although some might argue that they are closer to what Alan Kay envisioned). I am just wondering how to properly re-use code (i.e. avoiding code-duplication), and how to talk to two different bu…

I say In FP you do everything by operate on pure functions, functions composition, higher order functions. So for example you can have higher order function drive-common with common logic for drive that has as input parameter lower order function with logic specific to Car car-specific or Vehicl…

Yep protocols are interesting. They allow to add implementation for protocol (interface in OOP) functions to existing module without modifying code of this module. Maybe something like monkey patching but much better.

Thank you. Protocols indeed seem to be what I was looking for.
