5## Usage {#sec-pkgs.makeSetupHook-usage}
6
7```nix
8pkgs.makeSetupHook {
9 name = "something-hook";
10 propagatedBuildInputs = [ pkgs.commandsomething ];
11 depsTargetTargetPropagated = [ pkgs.libsomething ];
12} ./script.sh
13```
14
15### setup hook that depends on the hello package and runs hello and @shell@ is substituted with path to bash {#sec-pkgs.makeSetupHook-usage-example}
16
17```nix
18pkgs.makeSetupHook
19 {
20 name = "run-hello-hook";
21 # Put dependencies here if they have hooks or necessary dependencies propagated
22 # otherwise prefer direct paths to executables.
23 propagatedBuildInputs = [
24 pkgs.hello
25 pkgs.cowsay
26 ];
27 substitutions = {
28 shell = "${pkgs.bash}/bin/bash";
29 cowsay = "${pkgs.cowsay}/bin/cowsay";
30 };
31 }
32 (
33 writeScript "run-hello-hook.sh" ''
34 #!@shell@
35 # the direct path to the executable has to be here because
36 # this will be run when the file is sourced
37 # at which point '$PATH' has not yet been populated with inputs
38 @cowsay@ cow

40 _printHelloHook() {
41 hello
