Re: [Configobj-develop] configspec and MissingInterpolationOption error

[Robert Š. <smo...@gm...>]

Hi,
response is unbelievable quick enough if compared to our R&D ;)

Here is the code to reproduce the problem:

>>>>>>>>>>>>>>>>>>
from configobj import ConfigObj, flatten_errors
from validate import Validator

#some defaults
_pidFile = '/var/run/xdr.pid'
_defaultLogFormat = '%(asctime)s - %(levelname)s - %(message)s'

#configspec is used to validate configuration file
_configspec = ('''
[general]
pid_file = string(min=1, max=100, default=%s)

[logging]
level= option('INFO','DEBUG','CRITICAL','ERROR', default='INFO')
log_format = string(min=1, max=100, default=%s)
''' % (_pidFile, _defaultLogFormat)).split('\n')

#dummy config file
configFile = ''


#main loop, if called as a program start main
if __name__ == '__main__':
    validator = Validator()
    config = ConfigObj(configFile,configspec=_configspec)
    results = config.validate(validator)
 <<<<<<<<<<<<<<<<

The problem is, config['log_format'] should be '%(asctime)s -
%(levelname)s - %(message)s'
and the values 'asctime' are interpolated when using logging facility,
but they are evaluated during validation. Perhaps I just need to
somehow properly escape?

Thanks,

Robert
