sorry for the delay
just one comment, otherwise LGTM.
not sure how you want to proceed for the unit tests: either 1) the current tests can be converted to stop relying on the global client (and we can add one simple test to make sure the global client still works), or 2) we can keep the current tests as they are and add a simple test for the "scripting" use case

I feel like set_global_client is actually not needed in setup:
- when using p4runtime_sh for scripts, there is no need for global client support IMO
- when using p4runtime_sh as a CLI, setting the global client can be done here, in the
mainfunction

@antoninbas I started de-coupling the
client/contextfields. Here is my current approach which should not break the current prompt.However, there are breaking changes for people who use scripting:
p4runtime_sh.shell.clientwas renamed top4runtime_sh.shell.global_clientp4_runtime_sh.shell.contextwas moved into thecontextfield onP4RuntimeClientSo, if library users use
p4_runtime_sh.shell.clientandp4_runtime_sh.shell.contextdirectly (which is not documented in the README), they will get undefined-errors.While this is a breaking change, I am convinced that moving the
Contextinto theP4RuntimeClientis the right way since the context is closely coupled to the client. For example, when setting the forwarding config via theP4RuntimeClient, theContextshould be adapted as well.To make clear that we introduce "breaking" changes, we can introduce versioning, e.g., by tagging the repo in the current state as
v1and directly moving tov2with my changes.🚧 Important: these changes were only tested manually. I will add unit tests as soon as the general approach is approved!
