Print javascript function tree

Question

I need to parse some javascript code and print a tree of function declarations and calls (and nothing else).

Something like this:

function test3()

function test()
  declares 
    function test2()
      calls test3()
  calls test2()

What is the fastest and easies way to do this ? I have multiple functions and files.

I've tried using Antlr, spent 2 days and finally gave up, it's too complicated for me.

Any help will be appreciated.
