This kind of problems is similar to the one mentioned in another thread about modifying config options after executing commands. In that case I mentioned that the same dict-like interface also holds for WinReg and so on ...

So thinking big (yes ! I have a big head ! ) I think that the best approach in this case is to build an adaptation (simple) layer on top of ConfigParser, JSON, WinReg, PyCode, YAML, ... and build specific extensions for these formats . Perhaps the proper interfaces are already there (e.g. dict, shelve ) and I'm just blind and looking somewhere else ;o) Sorry, you've lost me :-)

Never mind . I was just trying to say that using dict, an adapter could be implemented (if not already there ;o) for multiple formats like the ones I mentioned above and the solution would cover many config formats ... and also I was saying that I was not sure about whether this is correct , I mean for ANY config formats, but definitely will work for many ;o)

Why ? So I'm free to mutate self.config as I see fit.

why not to let the user do it if he | she thinks so. I mean if somebody supplies in a temporary mapping that can be written then why to spend that time cloning the dict ? If the function has side-effects, well just document it ;o)

extension is cool ... what's the point about adding the new method instead of using DictConfigurator directly ? When you say "the new method", if you mean "configure" - the pattern is so that a subclass can override init and do additional setup before configure() is called.

Sorry I was confused. I was talking about dictConfig FUNCTION (to be added to logging.config ... isn't it ? ;o). I mean if dictConfig is sematically equivalent to a simple dc.configure why to add such function ?

PS: Not a big problem anyway ;o)
