This code is a work-in-progress prototype! Proper documentation is not yet written!
For now it is able to rename local variables, definitions, attributes, parameters that can be assumed to be private to the module (all their uses should be inside the obfuscated script and can be renamed as well). The idea is to remove some degree of information from the script without changing its behaviour. The obfuscated script can be published to allow execution without making it unnecessarily easy to understand and modify it.
There are some limitations:
getattr()/setattr()/hasattr()etc. will not work for renamed attributes- Access to namespaces and attribute dictionaries will see the renamed identifiers.
This affects
locals(),globals(),__dict__etc. - Removing a local variable (with
del) to access a variable with the same name in a parent scope will not work. - ... there is more to be written!
