Feature: Dot notation in py configuration
chinghwayu opened this issue · comments
Can dots be enabled as a separator in python configuration files? That seems more intuitive that specifying _ or __.
Doesn't this work already as is?
Is the new test in the branch https://github.com/tr11/python-configuration/tree/python-config-dotted what you need?
I'd like to be able to specify conf.py as:
a.b = 3
Then load:
cfg = config_from_python(
["conf.py"], prefix="", separator=".", lowercase_keys=True
)
a.b would expand to {"a": {"b": 3}}
Is this possible?
Not sure how without creating object a and setting its members; a.b = 3 won't be valid without a defined. Are you planning on defining a as some sort of attribute-enabled dict or something like that?
ack... yes, I should've added that detail. How could I import in an attribute-enabled dict in config?
I think I figured it out...
from config.helpers import AttributeDict
a = AttributeDict()
a.b = 3
del AttributeDict
Yeah, that's what I meant. I think this is an import use case; I'll add it as an example to the docs and maybe promote the AttributeDict class to the config module (instead of the helpers).
I noticed that the AttributeDict class doesn't allow for nesting of more than 1 level. For example, you can't do something such as:
from config.helpers import AttributeDict
a = AttributeDict()
a.b.c = 3
del AttributeDict
For that, the user would need to use something like python-box. Not sure if you want to implement that but may be worth noting in the docs.
