I'm trying to convert a setup.py to use setuptools (specifically the docutils build, FWIW). The existing setup.py has some custom command stuff to run 2to3 on build.
Aside: I believe there's consensus now that 2to3 is not the best way to support Python 2.x and 3.x. It's not that hard to have a single source tree in a portable subset of Python 2.x and 3.x. See python3porting.com and https://pypi.python.org/pypi/six.
As I understand it, setuptools should do this automatically by using use_2to3=True.
So, I've changed the code to just do:
setup( ... packages=find_packages(), use_2to3=True, ... )
However, when I do python setup.py bdist_wheel, I find that docutils/__init__.py within the wheel still contains (for example)
class ApplicationError(StandardError): ...
So the StandardError -> Exception fixer isn't being run.
Am I doing something wrong here? The setuptools documentation isn't very clear on what I should do, or what to expect.
I wouldn't be surprised to learn that bdist_wheel doesn't support use_2to3, but I don't actually *know* that for a fact, since I never used 2to3. Marius Gedminas -- What goes up, must come down. Ask any system administrator.
