Id like to create a custom command type i guess you'd call it. the idea is every time the command is called it first checks its custom attribute then modifies that same attribute.

here is the code i have so far, though it doesn't work i hope it demonstrates what im trying to do.

class Perc(commands.Command):
    def __init__(self , func , basePrice = 10):
        super().__init__(func)
        self.basePrice : int = basePrice
        
    async def __call__(self, *args, **kwargs):
        # modify base price
        self.basePrice  = 10
        return await super().__call__(*args, **kwargs)
        
@Perc(basePrice = 25)
async def testPerc(ctx : commands.Context):
    await ctx.send("command called")

CodePudding user response：

You need to make the factory function that returns the new class. To decorate a function, you need @decorator(args) which does (decorator(args))(func). This is why __call__ does not work.

If you look at the source code
