package module: counting non-system packages with a custom shell script

[rsenna]

Hi 👋🏽

New fastfetch user here. Really liking the tool.

I was trying to show a new record with totals for some "custom" package managers I'm using, based on this past discussion.

Note

The example shown in the link above has a small bug for the npm package count.
Since that shell snippet is based on directories, it might show wrong values if you have ever uninstalled global packages.
That's why it's best to use the tool itself (npm) to list and count packages, like I'm doing in the snippet below.

So I wrote a (not so) small nushell script to provide it for a couple of package managers - asdf, npm and uv in my case - but which can easily be extended (or rewritten in another shell such as bash, zsh, fish, if you prefer...):

EDIT: moved code to a gist.
