Freezes the install_requires in your setup.py
What it does: setup-freeze will edit your setup.py for you, pinning your install_requires to the exact version that you have installed.
What it doesn’t do: Add or remove entries in your install_requires. Touch any of the other arguments that specify requirements, like setup_requires or extras_require (yet).
How to use it: pip install setup-freeze, then cd to a directory with a setup.py in it and run setup-freeze.
What you need to know: Your setup.py needs to contain a call to setup(), with an install_requires argument set to a list, tuple, or set literal that contains string literals. It also needs to be UTF-8 encoded, and parseable by the version of Python that setup-freeze is installed in (so, if you install setup-freeze globally in Python 2, your setup.py needs to be Python-2-friendly even if you’re in a Python 3 virtualenv, or vice versa).
What you can do with the source code: Whatever you like, provided that you comply with the conditions of the MIT License.
What you shouldn’t blame me for: This is beta software, and as such comes with no guarantee that it won’t completely mess up your setup.py, delete your entire project, or set your computer on fire. I’m pretty sure it won’t, but having version control, backups, and fire extinguishers is good practice anyway, right?
