ConfigViper 0.3

Handles configuration saved as JSON files.

ConfigViper is a set of Python classes for handling configuration files saved in JSON format. For example:

from configviper import ConfigViper

ConfigViper.configure()

conf = ConfigViper()
conf.set('a.b.c', 'd')

And the JSON file will looks like:

{
    "a": {
        "b": {
            "c": "d"
        }
    }
}

Goals

1. Simple to define default values (avoiding “defaults” everywhere);

2. Simple to write converters between Python and JSON types (even for complex Python types);

3. Human editable format (JSON is readable enough);

4. Portable configuration format (JSON is portable enough);

5. Easy to add configuration options without destroying existing ones;

6. Accessible anywhere in the app code (avoiding singleton’s boring discussions);

7. Small and really simple.
