Has anyone done any choreographic programming with Elixir? The idea is that, instead of writing parts of a concurrent system separately and hoping that you’ve gotten the interactions between clients and server right, you instead write a choreography from some global viewpoint; a compiler of some sort then takes this choreography and constructs projections for each participant in the system.

A recent paper implemented an IRC client/server with choreographies: Real-World Choreographic Programming: Full-Duplex Asynchrony and Interoperability

Has anyone been working on something similar in Elixir?

I’m not 100% sure we are not doing this already in Elixir.

Care to share an example of how this would look like in for example an imperative language like golang or similar?

Highly doubt it, such concepts that involve a paradigm shift need to be extremely good for anyone to take them seriously. I can see how languages like Java could greatly benefit from it, however in Elixir I doubt this improves anything over existing way to write code.

yeah, i would say “we” do. it feels to me like actor model kind of stuff, sooner or later enters territory of orchestration or choreography.

i guess it comes with sufficient scale/complexity of the system.

OK, so it sounds like you’re saying that you (@fmn and @D4no0) feel like choreographies are a common paradigm in Elixir code (I agree based on my experience) but that no one is doing mechanical endpoint projection. That’s good! That means I’ve got some work to do. :slight_smile:

That’s very neat—it’s in an entirely different realm however. Good luck building it!
