nix-instantiate --eval {{[-E|--expr]}} {{expression}}

• Evaluate with machine readable output:

nix-instantiate --eval --xml {{[-E|--expr]}} {{expression}}

• Raw output, output of the function must be a string:

nix-instantiate --eval --raw {{[-E|--expr]}} {{expression}}

nix-instantiate --eval {{path/to/file.nix}}
