Open .cfg files on your Mac.

.cfg

Python packaging and tool settings (flake8, pytest, mypy) in INI style, sections and options at a glance.

Loper is a free, minimal editor for macOS that opens Python setup.cfg / tool config instantly and colors every part of the file, so you find the value you need at a glance and can fix it right there. No IDE, no project to load, no gray wall of text.
