Part of: https://github.com/NixOS/nixpkgs/issues/108938 meta = with stdenv.lib; is a widely used pattern. We want to slowly remove the `stdenv.lib` indirection and encourage people to use `lib` directly. Thus let’s start with the meta field. This used a rewriting script to mostly automatically replace all occurances of this pattern, and add the `lib` argument to the package header if it doesn’t exist yet. The script in its current form is available at https://cs.tvl.fyi/depot@2f807d7f141068d2d60676a89213eaa5353ca6e0/-/blob/users/Profpatsch/nixpkgs-rewriter/default.nix

# Provides a facility to hook into rfkill changes.

|
|
# Exemplary usage:
|
|
#
|
|
# Add this package to udev.packages, e.g.:
|
|
# udev.packages = [ pkgs.rfkill_udev ];
|
|
#
|
|
# Add a hook script in the managed etc directory, e.g.:
|
|
# etc."rfkill.hook" = {
|
|
# mode = "0755";
|
|
# text = ''
|
|
# #!${pkgs.runtimeShell}
|
|
#
|
|
# if [ "$RFKILL_STATE" -eq "1" ]; then
|
|
# exec ${config.system.build.upstart}/sbin/initctl emit -n antenna-on
|
|
# else
|
|
# exec ${config.system.build.upstart}/sbin/initctl emit -n antenna-off
|
|
# fi
|
|
# '';
|
|
# }
|
|

|
# Note: this package does not need the binaries
|
|
# in the rfkill package.
