Improve pkgx integration

[felipecrs]

Description

This improves the pkgx integration through the following:

• Now only pkgx-installed packages will be shown
  • pkgx can run any package without having to install it. When not installing, the package is just cached. The current implementation shows all currently cached packages, which in my opinion is not as useful as showing only the installed packages.
• Fix tea -> pkgx on macOS
• Check for pkgx regardless of the OS (they are working to support Windows, for example)

• pkgx list-installed pkgxdev/pkgx#985 (comment)

Screenshots

The only thing you'll notice is the decreased number of packages shown in the list, as only the installed packages will be shown.

Right, this is definitely a better way of detecting pkgx packages. Still, I really hope they add a list packages option tho, that would work better in case any package has more than one binary or stub command. But they seem to be moving nowhere after the primary focus shifted to the crypto aspect ☹️

Anyways, thanks!!

Me too, for sure.

Oh, this implementation handles it (through the sort -u).

Yeah, it's unfortunate to see pkgx project not receiving much love. But at least the pantry seems to be SUPER active: https://github.com/pkgxdev/pantry
