I want to use nix-shell which allows getting all tooling for a script
<https://nix.dev/manual/nix/2.34/command-ref/nix-shell.html#options>.
I’m trying to do
#!/usr/bin/env nix-shell
#!nix-shell ./env.nix -i factor
USE: io
IN: hello-world
: hello ( -- ) "Hello world" print ;
MAIN: hello
But when trying to exec my new script, I get
2: #!nix-shell ./env.nix -i factor
^
No word named '#!nix-shell' found in current vocabulary search path
The error makes sense if multiline shebangs aren’t supported (yet), but
I think this a bug & probably trivial fix.
------------------------------------------------------------------------
NOTE: I would prefer to use plain `nix-shell -i factor` but the factor
the binary ends up with a lower priority than `factor` from GNU
coreutlis — which means I have to do a hack with an ./env.nix file:
{ pkgs ? import <nixpkgs> { } }:
let
inherit (pkgs) lib factor-lang mkShellNoCC nix nixfmt;
in
mkShellNoCC {
buildInputs = [
(lib.hiPrio factor-lang.override { guiSupport = false; })
nix
nixfmt
];
}
