pkgs.makeSetupHook

pkgs.makeSetupHook is a build helper that produces hooks that go in to nativeBuildInputs

Usage

pkgs.makeSetupHook {
  name = "something-hook";
  propagatedBuildInputs = [ pkgs.commandsomething ];
  depsTargetTargetPropagated = [ pkgs.libsomething ];
} ./script.sh;

setup hook that depends on the hello package and runs hello and @shell@ is substituted with path to bash

pkgs.makeSetupHook
  {
    name = "run-hello-hook";
    # Put dependencies here if they have hooks or necessary dependencies propagated
    # otherwise prefer direct paths to executables.
    propagatedBuildInputs = [
      pkgs.hello
      pkgs.cowsay
    ];
    substitutions = {
      shell = "${pkgs.bash}/bin/bash";
      cowsay = "${pkgs.cowsay}/bin/cowsay";
    };
  }
  (
    writeScript "run-hello-hook.sh" ''
      #!@shell@
      # the direct path to the executable has to be here because
      # this will be run when the file is sourced
      # at which point '$PATH' has not yet been populated with inputs
      @cowsay@ cow

      _printHelloHook() {
        hello
      }
      preConfigureHooks+=(_printHelloHook)
    ''
  );

Attributes
