Nix-shell: how to specify a custom environment variable?
I am learning nixos and nix expressions. In the project folder I have created shell.nix and when I run nix-shell
I want it to set an environment variable for me. For example, to set PGDATA env var.
I know there are several ways to write nix expression files (I'm not used to most of them yet). Here's my example:
shell.nix
let
pkgs = import <nixpkgs> {};
name = "test";
in pkgs.myEnvFun {
buildInputs = [
pkgs.python
pkgs.libxml2
];
inherit name;
extraCmds = ''
export TEST="ABC"
'';
}
