Python: all plugins set initialization parameters

Summary

I am using Python and I add plugins through directories because I need to use nativecli for RPC calls in various Managers. I would like to know if it is possible to set self.nativecli directly for all classes in the NativePlugin using the following approach:

Current Implementation

Here is an example of how I am currently initializing the WeatherManager class within NativePlugin:

class WeatherManager:
    def __init__(self, **kwargs):
        self.nativecli: Client = kwargs.get('nativecli', None)
        return

    @kernel_function(description="...")
    def weather(self, location):
        return self.nativecli.weather(location)

And this is how I am adding the plugin:

kernel.add_plugin(
    parent_directory="plugins", plugin_name="NativePlugin",
    class_init_arguments={
        "XXXManager": {"nativecli": self.nativecli},
        "XXXManager": {"nativecli": self.nativecli},
        "XXXManager": {"nativecli": self.nativecli},
        ...
    }
)

Proposed Simplification

I would like to simplify the above approach by using a wildcard to set self.nativecli for all classes in NativePlugin. Here is the proposed implementation:

kernel.add_plugin(
    parent_directory="plugins", plugin_name="NativePlugin",
    class_init_arguments={
        "*": {"nativecli": self.nativecli},
    }
)

Question

Is the proposed wildcard approach feasible for setting self.nativecli for all classes in NativePlugin? If not, do you have any better suggestions for achieving this simplification?

Thank you for your assistance!

Hi @nblog, apologies for the delay on this: currently, we do not support wildcard arguments ("*": {"nativecli": self.nativecli}) for initializing multiple classes via class_init_arguments. The SDK implementation explicitly matches initialization arguments to class names individually.

A potential approach is to programmatically construct your initialization arguments, like this:

def init_args_for_all(nativecli, classes):
    return {cls: {"nativecli": nativecli} for cls in classes}

kernel.add_plugin(
    parent_directory="plugins",
    plugin_name="NativePlugin",
    class_init_arguments=init_args_for_all(self.nativecli, ["ManagerA", "ManagerB", "ManagerC"])
)
