Compile mixin to JS in JADE

问题

When trying to compile this JADE mixin (from their official docs)

mixin pets(pets)
  ul.pets
    - each pet in pets
      li= pet

into JavaScript using jade --client --no-debug pets.jade I get this output, which, as far as I can tell, doesn't actually do anything:

function template(locals) {
    var buf = [];
    var jade_mixins = {};
    var jade_interp;




    ;return buf.join("");
}

Is this a bug in the JADE compiler or am I doing something wrong? I was expecting it to compile it into something like function pets(pets)...

I'm on JADE 1.3.1
