nh os info

[NotAShelf]

Quick and dirty implementation for nh os info, which would list

• Information for current generation
• Rest of the generations (if any) in a formatted table

when executed. WIP, I'll be working on this once I have some more time. Feedback welcome.

Closes #198

[viperML]

Thank you for this. I guess you already know, but to sync:

• Set the command name to info, not generations
• Fix the "current" generation being displayed
• Add some color to the output with owo_colors

After this is merged, I'll look into adding more stuff to info, but that would be after.

[NotAShelf]

Yes I intend to get to all of those points (as we have previously discussed). This is here for visibility, and in case anyone wants to chime in.

Hopefully I will complete this in the following weeks when my mental load is a bit more bearable.

[NotAShelf]

Okay, implementation should be fine but I've not added colors. That can be done at a later date, or on maintainer's own discretion - I cannot come up with good looking colors.

Current design:

It is ready.

I just ran nh os info on macOS 15.2.
I got not a useful result

[NotAShelf]

nh os is for NixOS, not Darwin. I do not have any darwin systems to test (nor do I like the darwin ecosystem) so the implementation makes no effort to be compatible.

[bestlem]

@NotAShelf fair enough that was viperML's issue as well.

I would leave this here so someone like @ToyVo who does have access to macOS could see if it could be implemented.
