How to build python-packages depends on the output of other project
by Young Yang June 4, 2016

June 4, 2016

hi, I'm writing python-binding for project A. My python-binding depends on the compile output of project A(It is a .so file), and the project A is not installed in the system(so we can't find the .so files in the system libraries pathes) What's the elegant way to package my python-binding, so that I can install everything by run `python setup.py` ? Any suggestions and comments will be appreciated :) -- Best wishes, Young

Accessing tests_require and setup_requires from the setup.py
by Christopher Baines June 3, 2016

June 3, 2016

I'm trying to write a script to get information about a source distributions requirements (from the source distribution), but I'm not sure how to access the tests_require and setup_requires that can sometimes be found in the setup.py? Apologies if this is really simple, and I've just missed the answer, but I've searched for it a few times now, and not come up with anything. Thanks, Chris

Alternate long_description formats, server-side
by Nick Timkovich June 3, 2016

June 3, 2016

When I brought up enabling Markdown previously, I was a bit over-eager and started talking implementation before there was any sort of consensus about it in principle, so it was a bit of a straw-man. The previous discussion seemed to rest with the onus being on the user to do it themselves, perhaps by installing (the non-Python) pandoc (non-trivial on Windows) as well as pypandoc and then integrating it into twine or some such. There seems to be a chasm between the GitHubbers that have various issues and PRs to this effect on the pypa/readme_renderer repo that are met with a frustrating silence from people with commit-power. Is the solution to basically write a full spec (PEP?) before touching any code? That seems like an actionable solution, but is it simply going to be rejected out-of-hand because of the "just learn rST" sentiment among the maintainers?

Officially deferring the Metadata 2.0 specification
by Nick Coghlan June 2, 2016

June 2, 2016

Metadata 2.0 has been deferred-in-practice for quite some time, but I just updated the PEP itself to reflect the deferral and link to more of the incremental improvement PEPs: https://hg.python.org/peps/rev/94c1afae202e This makes the current policy that enhancement proposals should avoid depending on the definition and implementation of metadata 2.0 explicit. Regards, Nick. P.S. PEP 459 (standard metadata extensions) depends on 426, and has also been marked as Deferred -- Nick Coghlan | ncoghlan(a)gmail.com | Brisbane, Australia

PyPi upload fails with TypeError
by Luís de Sousa June 2, 2016

June 2, 2016

Dear all, I am trying to upload a new package to PyPi with this command: $ python3 setup.py sdist upload The process seems to go on well until the running upload bit, at which point I get this exception: Traceback (most recent call last): File "setup.py", line 33, in <module> "Topic :: Scientific/Engineering :: GIS", File "/usr/lib/python3.4/distutils/core.py", line 148, in setup dist.run_commands() File "/usr/lib/python3.4/distutils/dist.py", line 955, in run_commands self.run_command(cmd) File "/usr/lib/python3.4/distutils/dist.py", line 974, in run_command cmd_obj.run() File "/usr/lib/python3.4/distutils/command/upload.py", line 65, in run self.upload_file(command, pyversion, filename) File "/usr/lib/python3.4/distutils/command/upload.py", line 139, in upload_file user_pass = (self.username + ":" + self.password).encode('ascii') TypeError: Can't convert 'NoneType' object to str implicitly I verified that Topic :: Scientific/Engineering :: GIS is a valid topic. What else am I missing? Thank you, Luís Sent from [ProtonMail](https://protonmail.ch), encrypted email based in Switzerland.
