ConfigViper
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('spam.ham.eggs', 'sausage')
And the JSON file will looks like:
{
"spam": {
"ham": {
"eggs": "sausage"
}
}
}
Goals
Simple to define default values (avoiding “defaults” everywhere);
Simple to write converters between Python and JSON types (even for complex Python types);
Human editable format (JSON is readable enough);
Portable configuration format (JSON is portable enough);
Easy to add configuration options without destroying existing ones;
Accessible anywhere in the app code (avoiding singleton’s boring discussions);
Small and really simple.
Installation
Install ConfigViper using pip install ConfigViper command. If you downloaded the sources from PyPI go to ConfigViper-<version> directory and type python setup.py install command. You can also get the sources from BitBucket repository (you will need Mercurial SCM installed on your system):
