So I understand that you really require to call your code from outside
of emacs. When you're not in emacs, there's AFAIK no way to tell which
buffer is "current". You may have many buffers, and also any number of
frames and windows. This code takes the buffer that the first window
of the currently selected frame is pointing to, which will probably do
what you want: 

  (with-current-buffer (window-buffer (frame-first-window)) (current-word nil t))

HTH,
