Release Date: 2014-11-15 // over 9 years ago

  • 🆕 New features

    • defhandlecall, defhandlecast, and defhandleinfo for implementation of handlers only
    • 0️⃣ default arguments can be specified via \\
    • defcall and defcast can be called without specifying the body
    • 👌 Support for timeout and hibernate replies.

    💥 Breaking changes

    • Pattern matching now works on interface functions as well (previously it was done only in handler functions).
    • Starter functions are not automatically generated anymore. You can use defstart macro to create them.
    • When calling use ExActor.* options :initial_state, and :starters are not available anymore.
    • definfo is renamed to defhandleinfo
    • Option export: false is not available in defcall and defcast. If you want to implement just handlers, use defhandle*

    A non exhaustive list of changes you may have to do in your project:

    • ➕ Add explicit starters via defstart. If you need to support start and start_link, you can do it like this:
    defstart start(x, y)
defstart start_link(x, y) do
  # initialization runs for both start/2 and start_link/2
end
    • Replace all definit with defstart if possible, or use body-less defstart with an explicit definit.
    • If you used initial_state, set the state explicitly in defstart.
    • Replace definfo with defhandleinfo.
