It’s to allow interpolation of packages and environments. But in practice we don’t use it that often, so we were thinking of switching the main function to using just a second string argument. (In other words, I agree.)
import * as garn from "https://garn.io/ts/v0.0.14/mod.ts";
import * as pkgs from "https://garn.io/ts/v0.0.14/nixpkgs.ts";
export const main: garn.Executable = garn.shell`${pkgs.jq}/bin/jq --version`;
Put that in a 'garn.ts' file and run 'garn run main' and you should see the version of 'jq' that you can get from our 'nixpkgs' module.
But yeah, I completely agree with the sentiment here. This is a rather cumbersome syntax to support a use-case that we don't even have examples for. So clearly the normal usage shouldn't force you to use template strings.
