On approximately 10/7/2009 7:49 AM, came the following characters from
the keyboard of Vinay Sajip:
In outline, the scheme I have in mind will look like this, in terms of the new
public API:
class DictConfigurator:
def __init__(self, config): #config is a dict-like object (duck-typed)
import copy
self.config = copy.deepcopy(config)
def configure(self):
# actually do the configuration here using self.config
dictConfigClass = DictConfigurator
def dictConfig(config):
dictConfigClass(config).configure()
This allows easy replacement of DictConfigurator with a suitable subclass where
needed.
Concept sounds good, and the idea of separating the syntax of the
configuration file from the action of configuring is a clever way of
avoiding the "syntax of the (day|platform|environment)" since everyone
seems to invent new formats. So people that want to expose a text file
to their users have the choice of syntaxes to expose, and then they do
logCfg = readMyFavoriteSyntax( logCfgFile )
# or extract a subset of a larger config file for their project
DictConfigurator( logCfg )
But DictConfigurator the name seems misleading... like you are
configuring how dicts work, rather than how logs work. Maybe with more
context this is not a problem, but if it is a standalone class, it is
confusing what it does, by name alone.
