[BUG] NixOS Packages not being detected

[HeitorAugustoLN]

General description of bug:

• What happened: nix-user packages not being shown and some of the nix-system packages not being detected
• What should happen: nix-user packages should be shown and all nix-system packages should be detected
• Fastfetch version used: 2.12.0
• Did it work in an older version: I don't know, first time using fastfetch
• Where did you get the binary: Nixpkgs unstable
• Does this issue still occurs in the latest dev build? Couldn't test

If fastfatch crashed or freezed

Paste the stacktrace here. You may get it with:

# You may need Ctrl+C to stop the process if it freezes
gdb -q -ex 'set confirm off' -ex run -ex 'bt full' -ex quit --args /path/to/fastfetch

If you are able to identify which module crashed, the strace can be helpful too

strace /path/to/fastfetch --multithreading false -s {MODULE} --pipe

If you cannot do the instructions above, please upload the core dump file:

If fastfetch is slow

Use time fastfetch --stat to show time usage for each module.

If my image logo didn't show / work

• The image protocol you used:
• The terminal you used:
• Upload the image file here, or paste the image URL:
• Does it work with --logo-width {WIDTH} --logo-height {HEIGHT}?

If fastfetch behaves incorrectly on shell starting

• The bug is reproduceable with fresh / clean shell configuration (i.e. fastfetch is the single line of .zshrc or ~/.config/fish/config.fish):
• Does sleep 1 before running fastfetch work?

The neofetch output for nix package count is inaccurate. Neofetch counts the output of nix-store -qR /run/current-system/sw, which

1. Misses some packages in /run/current-system/sw/kernel and other folders. diff <(nix-store -qR /run/current-system/sw) <(nix-store -qR /run/current-system)
2. Incorrectly take a lot of meta packages into account. eg. nix-store -qR /run/current-system/sw | grep -e 'man$'

I don't know why nix-user doesn't work. It does work for me in VM. Maybe remove this line https://github.com/fastfetch-cli/fastfetch/pull/844/files#diff-7e1606f87baf0c6ee9d09351142102852dc3b5e7db95290e5774287d6d93ae8aR514 @xoltia

Oh, i didn't know that.
Maybe it is not working because both .nix-profile and $XDG_STATE_HOME/nix/profile exists for me, but i'm not sure

Nice!
