Kwargs in messenger

Is keyword arguments supported in messenger?

   def some_function(self, a=1, b=2, c=3):
       some function
   messenger.send('event name', [c=5]) 

in the above example, is it possible to pass specific variable values?
or the only solution would be messenger.send('event name', [1,2,5]) ?

This is not supported at the moment. Do you have a use case where this is necessary?

Instead of relying on kwargs, you could pass a dictionary:

def some_function(self, args_dict):
    defaults = {'a':1, 'b':2, 'c':3}
    args_dict = defaults.update(args_dict)
messenger.send('event name', [{'c':5}])

This isn’t as clean as kwargs, but it should do the trick.

That said, it would not be particularly hard to add this feature, so feel free to add this as a feature request, if you can show a good use case.

Not necessary, was just thinking a clean way to pass specific arguments in messenger.
But I think Moguri’s solution was a clean and elegant alternative to **kwargs!! :+1:

could definitely use this. Passing a dict is fine in most cases but not as pythonic :wink:

However, I am also currently hooking into some other code which uses the **kwargs magic and I need to create a dict handler to pass to my functions


def messyKwargPasser(f, arglist, kwargdict):
     return f(*arglist,**kwargdict) 

def foo(*args,**kwargs):
    print("args: ", args)
    print("kwargs: ", kwargs)

base.accept("mouse1", messyKwargPasser, extraArgs = [ foo, ['hello' ], {'well':'hi there'} ] )

would be nice to have some functionality like

base.accept("mouse1", foo , extraArgs = ["hello"], extraKwargs = {'well':'hi there'} )
