[Configobj-develop] python objects in config files

[Iain M. <iai...@gm...>]

Hi all,

I have a need to specify a python class (as opposed to a string 
referring to said class) as the value of a ConfigObj config variable.

If I do so without importing the relevant module in the config file, 
then I get a "configobj.UnreprError: Unknown name or type in value". If 
I import the module at the start of the config file, then I get a parser 
error, cos its not good config file syntax.

I realise its a bit outside scope of a Win INI, but was hoping that 
somebody might have had a similar problem before and know a solution.

Thanks
Iain

I'm afraid you can't do it within ConfigObj. Allowing it would allow the 
loading of a config file to trigger code execution, which is potentially 
unsafe and outside the scope of ConfigObj.

You could pickle objects into strings and store them in ConfigObj which 
would also be pretty evil. Best to allow the storing of names 
corresponding to objects and turn it back into an object yourself.

All the best,

Michael
