Works with: https://github.com/mtomwing/freeseer/tree/config_refactor/src/freeseer/framework/config

test.py

from freeseer.framework.config.options import StringOption, IntegerOption
from freeseer.framework.config.persist import ParserConfig


class FreeseerConfig(ParserConfig):
    name = StringOption('Michael Tom-Wing')
    age = IntegerOption(0)


if __name__ == '__main__':
    config = FreeseerConfig('/tmp/freeseer.conf', 'Global')
    config.load_if_possible()

    print 'Name:', config.name, type(config.name)
    print 'Age:', config.age, type(config.age)

    config.age += 20

    print 'Name:', config.name, type(config.name)
    print 'Age:', config.age, type(config.age)

    config.save()

The file it generated:

thinkpad[~] cat /tmp/freeseer.conf 
[Global]
age = 100
name = Michael Tom-Wing
