`pkgs.makeSetupHook` is a build helper that produces hooks that go in to `nativeBuildInputs`
|
||
|
|
|
||
|
|
## Usage {#sec-pkgs.makeSetupHook-usage}
|
||
|
|
|
||
|
|
```nix
|
||
|
|
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 {#sec-pkgs.makeSetupHook-usage-example}
|
||
|
|
|
||
|
|
```nix
|
||
|
|
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

#!@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
