Subject: [Cython] Running doctests with Cython?
To: [email protected]: [email protected]
I'm cythonizing an existing module with lots of doctests, which would be useful
in catching any errors or changes in behaviour that might result. However, I
have trouble running doctests in a cython-compiled module. The compiled module
offers the usual __doc__ strings (simple example follows below), yet python -m
fails with "No code object available". Is there a trick?
