Misc tips

This page contains stuff that ~~I couldn't be bothered to move to the new format~~ is probably outdated or just short tips.

previously: tops and bottoms

@ (at) syntax

very simple.

args@{a, b, c, ...}: {
  # args.a and a are the same
  some = "value";
}

nginx regex location

{
  locations."~ \.php$".extraConfig = ''
    # balls
  '';
}

from nixos wiki

adding a package with an overlay to a package set

for package sets with a scope, you will have to do something like

final: prev: {
  nimPackages = prev.nimPackages.overrideScope (final': prev': {
    sha1 = final'.callPackage ./sha1.nix {};
    oauth = final'.callPackage ./oauth.nix {};
  });
}

There's an alternative method that i used to use here:

however i do not think that's the best way lol

what the hell is an IFD??

IFD stands for import from derivation.

nixos/nixpkgs really need better and significantly less scattered documentation while improving manual readability.
