Invalid syntax in generated version.py

A package I use is distributed through Mercurial and uses setuptools_scm with setup.py like this

from setuptools import setup
setup(
    use_scm_version={
        'write_to': 'PACKAGENAME/version.py',
    },
    setup_requires=['setuptools_scm'],
#...
)

The resulting version.py is not valid python:

# coding: utf-8
# file generated by setuptools_scm
# don't change, don't track in version control
version = <ScmVersion 0.4.0 d=None n=None d=False x={}>

The issue did not occur before today, it seems that it is caused by v1.12.0 release.

Same issue here.

yikes, in response i pulled the release of pypi, i am now working on a fixup

BTW this reordering creates the issue: 80565e3#diff-cc3eb8241d67f6487179a3c8976e128eR107

format_version's rv is not used for dump_version.

i am aware, i'm testing the fix and i started Hungarian notation (parsed_version vs version_string) plus type assertions

ouch, sorry - my bad. i assumed that since tests passed, things were okay. looks like the test suite was incomplete!

[RonnyPfannschmidt]

@anarcat @untitaker please take a look at the pr

[untitaker]

Fix lgtm. No tests though :P

[RonnyPfannschmidt]

i#ll fix in a different manner

[RonnyPfannschmidt]

the result of parse will always be a parsed version now
