How to pass environment variables while running nix-shell

[aszenz]

I have a project which needs the NIXPKGS_ALLOW_UNSUPPORTED_SYSTEM=1 env variable to be set before it can work, just wondering how to activate the nix environment in vscode for the same, right now it fails

@aszenz Unfortunatel, the extension doesn't support env variable before executing nix-shell. I think I can add the ability in a new release. But now I can suggest you workaround.

You can create custom script with shebang line, make it executable and pass in config for the extension instead of nix-shell. I hope it will work.

Something like:

#!/bin/bash
export NIXPKGS_ALLOW_UNSUPPORTED_SYSTEM=1
nix-shell $@
