Nix antiquotation

Within Nix strings^ᛦ, the result of any Nix expression which can be coerced to a string can be interpolated into the string with the syntax ${expression} where expression is the Nix expression.

Examples

• Simple string "Path to hello: ${hello}"

• Indented string

  ''
  What if I wanted the path to hello
  down here?
  ${if wantPathHere then ${hello} else ""}
