=== runCommand + builder.sh === | |||
Instead of <code>stdenv.mkDerivation</code>, we can also use <code>runCommand</code> to call an external bash script: | |||
<syntaxHighlight lang="nix"> | |||
# default.nix | |||
{ | |||
outputTxtPath = runCommand "output.txt" { | |||
nativeBuildInputs = [ coreutils jq ]; | |||
# only strings can be passed to builder | |||
someString = "hello"; | |||
someNumber = builtins.toString 42; | |||
someJson = builtins.toJSON { dst = "world"; }; | |||
} (builtins.readFile ./builder.sh); | |||
} | |||
