>From what I understand in PEP 345, "Requires-Dist" is the name in PKG-INFO files for a distribution's dependencies on other distributions.
>From what I also understand from personal experience, when using setuptools, install_requires is the name of the keyword argument to setup() that specifies a dependency on another distribution. Sanity-check: This doesn't mean that one should call setup() with a "required_dist" keyword argument, right? Relatedly, https://mail.python.org/pipermail/distutils-sig/2010-January/015211.htmlseems to suggest that one day in our glorious future, when we can lay down our setup.py files and switch to setup.cfg, then we can call it requires_dist in that format. As I understand it. the setup.cfg revolution never happened, so I should still encourage new people packaging their own things to write install_requires in their calls to setuptools.setup(). Also, I just created a trivial setup.py that contains an "install_requires" and doing "python setup.py develop --user" does seem to have created a PKG-INFO file, but it doesn't have a "Requires-Dist" line. Details of my test case: ➜ rofl python Python 2.7.6 (default, Mar 22 2014, 15:40:47) [GCC 4.8.2] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import setuptools >>> print setuptools.__version__ 3.4.2 ➜ rofl cat setup.py from setuptools import setup setup(install_requires=['mwparser']) ➜ rofl grep mwparser UNKNOWN.egg-info/* UNKNOWN.egg-info/requires.txt:mwparser I expected to also see it in a Requires-Dist property within UNKNOWN.egg-info/PKG-INFO. Is that a mistaken expectation? If so, what if anything writes a "Requires-Dist" line anywhere? Thanks for your patience with me, and for your speedy responses so far! I'm really hoping to provide as much high quality information to people at PyCon as I can, and grateful that so many wise people are willing to have these conversations with me. -- Asheesh.
