How to install and test from source?

[ctrueden]

I'm interested in helping move this extension forward, but I don't know how to install it from source. Could you offer some brief instructions? Since I'm on Ubuntu 20.04, I'd like to help finish the ubuntu-focal branch (is it functional yet?).

The version in ubuntu-focal is written in Python so the interpreter should be enough.
I'm sorry for such short answer but I don't use Ubuntu nor Debian on desktop so I don't know more.

I cloned the source, then created a conda environment with Python 3.8.6, pygobject and python-xlib packages. Running python mousewheelzoom.py launches without complaint, but no combination of modifier keys plus mouse wheel seems to do anything. There does not seem to be any interaction with GNOME's usual accessibility zoom feature (super+alt+8 to toggle the zoom feature, then super+alt+= or super+alt+- to zoom in and out, respectively).

I tried reading about how to install GNOME extensions but it's opaque to me how dropping this repository into ~/.local/share/gnome-shell/extensions could possibly do anything... there is no metadata.json for one thing, and even if there were, I don't see how it would link the Python script to any sort of execution by the GNOME extensions framework.

I guess I'm just too much of a noob to help here, without pointers to the proper documentation.

I don't think you are noob and if so then we both are.

Regarding your research: You do everythink correct - the Gnome API changed.

We need to change the code.

It looks like it was using the gnome magnifier and contacting it over dbus, any info on the changes to gnome magnifier ?
