How to package a command line tool in Nix?
Suppose you have a simple collection of scripts bash
that make up a command line tool, with a main script in bin/
and some library scripts in lib/
, all of which will be packaged with Nix with tool.nix
s default.nix
for convenience:
scriptdir
└─ bin/
└─ tool
└─ lib/
└─ default.nix
└─ tool.nix
What should it look like tool.nix
to properly package this tool to be tool
wrapped with tool <args>
?

After some help IRC works tool.nix
:
{ stdenv }:
let
version = "0.0.1";
in stdenv.mkDerivation
rec
{
name = "tool-${version}";
src = ./.;
installPhase =
''
mkdir -p $out
cp -R ./bin $out/bin
cp -R ./lib $out/lib
'';
}
For completeness it default.nix
will look like
{ pkgs ? import <nixpkgs> {} }:
pkgs.callPackage ./tool.nix {}
and can be set by calling nix-env -f ./default.nix -i
from scriptdir
.
