[Python-apps-team] Bug#780084: pyflakes and pyflakes3 don't pay attention to shebangs leading to invalid syntax errors

[Paul Wise]

Package: pyflakes
Version: 0.8.1-1
Severity: normal
Usertags: check-all-the-things

As you can see below, pyflakes and pyflakes3 don't pay attention to
shebangs, leading to invalid syntax errors. This makes both of them
harder to use since you have to check the current directory for what
kind of Python scripts are present and only pass those ones to pyflakes.

pabs at chianamo ~/tmp-test-pyflakes-pyflakes3 $ head *.py
==> bar2.py <==
#!/usr/bin/env python2
print 'foo'

==> bar3.py <==
#!/usr/bin/env python3
nonlocal foo

==> bar.py <==
#!/usr/bin/env python
print 'foo'

==> foo2.py <==
#!/usr/bin/python2
print 'foo'

==> foo3.py <==
#!/usr/bin/python3
nonlocal foo

==> foo.py <==
#!/usr/bin/python
print 'foo'
pabs at chianamo ~/tmp-test-pyflakes-pyflakes3 $ pyflakes .
