A CLI tool for watching, getting, and setting configuration variables

[hadilq]

I was using dconf in GNOME, here to setup my custom configuration. It has three functionality that I really liked.

• it could watch for the configuration changes by other tools. I just needed to run dconf watch, then do my change in other applications to see what config has change.
• I could read the config.
• I could set them, which comes very handy in my declarative setup with home-manager, here

So here I propose to have a similar CLI tool for COSMIC as well. It will solve the config file format for everyone, since any format could be read by a parser and run this CLI tool! Use JSON, TOML, XML, NIX whatever you like for the configs.
