add support for Python 3.5 infix matrix multiplication

[zackmdavis]

This came up while working on a momentarily forthcoming pull request (the topic of which can be easily inferred) for Hy.

CI informs me that this project is supposed to be Python 2.6–compatible, where the @unittest.skipIf decorator I had tried to use doesn't exist. Fixed-up and force-pushed.

[berkerpeksag]

Could you also add a test to test_codegen.py?

[zackmdavis]

Hm. f27c059 uses unittest2 if available (and also adds a test to test_codegen), but CI fails again on Python 2.6 ('module' object has no attribute 'skipIf').

[berkerpeksag]

There's a typo in the import statement :)

import unitttest2 as unittest

See three t in unittest2.

[zackmdavis]

(force-pushed) Okay, what about 30b310d? In addition to using the correct number of ts in "unittest2", it explicitly checks for for SkipTest, and avoids the context-manager form of assertRaises, so it should work on Python 2.6 regardless.

Thanks! The test looks good. We can simply the other test a bit:

@unittest.skipUnless(sys.version_info >= (3, 5), "ast.MatMult introduced in Python 3.5")
def test_get_mat_mult(self):
    self.assertEqual('@', astor.misc.get_binop(ast.MatMult()))

(amended again)

[berkerpeksag]

Thanks! :) I will release 0.5 today or tomorrow.
