Is libcaf_python gone? #1081

Closed alatdneg closed 4 years ago

alatdneg commented 4 years ago

Hi, I'm trying to implement a python module , using libcaf_python, but I've just noticed that it's now gone, and atom_value is also gone.

I updated my build off master a few weeks ago, and only just noticed the changes.

Is it still possible to do this ? And if so what should I replace atom_value with ?

Cheers.

I've almost got it working, but the atoms are causing me grief, I can't work out how to set them up so they are recognised by python and the c++ code.

We recently dropped libcaf_python: https://github.com/actor-framework/actor-framework/issues/775#issuecomment-608623572. That's not to say that we wouldn't add Python bindings in the future again, just that the Python shell didn't had a purpose any more at the moment.

what should I replace atom_value with ?

CAF 0.18 is going to implement atoms using tag types. The simplest way to define them is by using the CAF_ADD_ATOM macro. As an example of the new API, you can have a look at the dining philosophers.

As to how to make binding to the new atoms: either one creates one Python type per atom or one could create a dictionary to look up types by name at runtime.

We will also update the docs if CAF 0.18 nears completion.

Finally got it working, didn't realise you now need to register each "atom" as a message type as well, couldn't workout why the remote wasn't receiving any messages.

cheers
