As the author of QuickTile, which is written in Python but even closer to what you describe than a window manager would be, I have to say that, yeah, doing X11 stuff takes a lot of knowledge that's not ideally documented in non-print sources. Source: over 1 year ago

Actually, I plan to add a .nojekyll file and then use something like Pelican with custom plugins, then set GitHub Actions to run my update.sh on push... Similar to how http://ssokolow.com/quicktile/ is a Sphinx-based site hosted on GitHub Pages and automatically regenerated from the pushed sources. Source: about 2 years ago

I've been using ssokolow.com/quicktile for this purpose, it does what I need and doesn't replace the wm. Source: about 2 years ago

The best I could do for the API documentation for this project of mine was to use the automodule directive to autogenerate at the coarsest level possible and remember to never create new .py files if I could possibly avoid it. Source: almost 3 years ago

Then, I can only suggest http://hammerspoon.org/ and then you can start implementing window movement using it https://www.hammerspoon.org/go/#winmoveintro. Source: almost 1 year ago

MacOS doesn't do this natively, but you have options: - If you just want to move windows around with some degree of keyboard customization, go for Rectangle. - If you want more control, such as sizing a bunch of windows at the same time, use Slate. - If you can code and want really high degrees of customization, you won't go wrong with Hammerspoon.

Both of those can be replaced by the open-source Hammerspoon (actually a significant number of the things in this thread can, including BTT). Source: about 2 years ago

Depending on what you want from KM, Hammerspoon may be a good alternative. You can also look up on AlternativeTo for other options. Source: over 2 years ago
