Implementation

The following is the current implementation of this function.

getExe' =
    x: y:
    assert assertMsg (isDerivation x)
      "lib.meta.getExe': The first argument is of type ${typeOf x}, but it should be a derivation instead.";
    assert assertMsg (isString y)
      "lib.meta.getExe': The second argument is of type ${typeOf y}, but it should be a string instead.";
    assert assertMsg (match ".*/.*" y == null)
      "lib.meta.getExe': The second argument \"${y}\" is a nested path with a \"/\" character, but it should just be the name of the executable instead.";
    "${getBin x}/bin/${y}";
