Run ncspot in the background using tmux

[Jiogo18]

ncspot user interface is nice, but sometimes we just want the music without terminal.
Here is a solution that allows you to use ncspot in the background.

1. Start a ncspot instance with tmux new -s ncspot -d ncspot
2. Open with tmux attach -t ncspot
3. Detach with Ctrl+b, d (the instance will still run in the background with tmux)
4. Stop with tmux kill-session -t ncspot

Add the keybind "q" = "exec tmux detach > /dev/null to detach by pressing q.

Advantages

It is possible to attach to the same instance multiple time,
so you don't have to find which terminal you started ncspot with.

Start as a service

Create a service of Type=forking, set ExecStart and ExecStop with the above commands.

Smaller footprint

ncspot uses 38 MB in my case
But this measure is missing the terminal and the shell.

With a custom configuration:
The terminal takes 125-150 MB (shared with multiple shell)
The shell takes 44-50 MB

With a lighter terminal+shell:
xterm and bash use around 17 MB

With tmux/screen:
The screen+bash takes 6 MB,
When detached, no terminal+shell is required
When attached, add 4 MB to the terminal+shell measure

Not a huge deal in front of the incredible 35-46 MB of ncspot, but not negligible.

screen

The original post used screen, which doesn't work well for ncspot (click will freeze).
If you prefer screen:

1. Start a ncspot instance with screen -dmS ncspot ncspot
2. Open with screen -S ncspot -x
3. Detach with Ctrl+a, d or with exec screen -d > /dev/null for the keybind
4. Stop with screen -XS ncspot quit
