A little orm for config file, do transformation to/from python object

example.ini:

[Section1]
bool_field = True
int_field = 123
#int_default_field = 567
float_field = 456.7
string_field = hello, world

[Section2]
ip_field = 127.0.0.1
ipport_field = 127.0.0.1:12345
ipport_list_field = 127.0.0.1:12345, 127.0.0.2:12346

    [Section3]
    choice_field = release

example.py:

from ormconfig import *
import sys

class MyConfig(Config):
    class Section1(Section):
        bool_field = BoolField()
        int_field = IntField()
        int_default_field = IntField(default='default value 6')
        float_field = FloatField()
        string_field = StringField()
    class Section2(Section):
        ip_field = IPField()
        ipport_field = IPPortField()
        ipport_list_field = ListField(IPPortField())
    class Section3(Section):
                    choice_field = ChoiceField(StringField(), ['debug', 'release'], 'debug')

try:
    config = MyConfig.load('example.ini')
except Error as e:
    print('Failed to load file: %s' % str(e))
    sys.exit(1)

print(config.Section1.bool_field)
print(config.Section1.int_field)
print(config.Section1.int_default_field)
print(config.Section1.float_field)
print(config.Section1.string_field)
print(config.Section2.ip_field)
print(config.Section2.ipport_field)
print(config.Section2.ipport_list_field)
    print(config.Section3.choice_field)

output:

True
123
default value 6
456.7
hello, world
127.0.0.1
('127.0.0.1', 12345)
[('127.0.0.1', 12345), ('127.0.0.2', 12346)]
    release
