Chorex is a brand-new Elixir library for choreographic programming: Chorex provides a macro-based DSL that lets you describe how processes communicate to perform a computation. This top-down description of interacting processes is called a choreography. From this choreography, Chorex creates modules for each process that handle all the message-passing in the system. The interactions performed by the generated code will never deadlock by construction because the choreographic DSL ensures that no processes will be waiting on each other at the same time.
