hammerspoon VS bitbar

You'll be disappointed because my use case is pretty simple - move the dock, remaximize all windows on the main screen and move chrome to my secondary screen.

Maybe you can use AnyBar https://github.com/tonsky/AnyBar/ or xbar https://xbarapp.com/

xbar (Free) xbar is free and open source it allows you to put anything in your macOS menu bar, although the learning cure is high, I would put this in development too..

There’s some discussion in that in https://github.com/matryer/xbar/issues/691. Note that this XBar plugin likely won’t work out of the box since it uses some macOS-specific tools, but it can likely be ported.

Then it will create a menu bar entry titled "Hello" with a single element in its drop-down menu, which will open Hacker News when clicked. You place your program in a specific directory for xbar to run, and it can be configured to run at a given frequency, e.g. once a minute to report the results of an API call or some measurement from your system, etc. Up to you to build the menu bar app you want.

As an exercise, I've implemented a basic (and very hacky) UI for tailscale(1) as an xbar [1] plugin: https://gist.github.com/notpushkin/aa36c2d34e3e7180aa66ed2a5...

tailscaled isn't particularly stable on my machine though, so I guess I'll roll back to the closed source version. However, this could be a starting point for a Linux client!

Since everyone here like scripting, May I suggest, if you have not used it already, checkout Xbar (https://xbarapp.com/) for Mac and Argos (https://argos-scripts.github.io/) for Linux.

I have used these 2 on my machines for the last 4 years and writing tons of script for myself, here are a few:

If you use Nightscout, there is an app called XBar for MacOS which has a plugin that reads your nighscout and put displays it on your menu bar.
