Message-ID: <18667.25652.771618.151560@gargle.gargle.HOWL> (raw)
I've been using the following mods to json.el with good results,
am attaching diff output.
Change Summary:
Use forward-char in json-advance
Use skip-syntax-forward to implement skipping whitespace
diff json.el ~/sourceforge/emacs/lisp/json.el

< (forward-char n))

> (unless n (setq n 1))
> (let ((goal (+ (point) n)))
> (goto-char goal)
> (when (< (point) goal)
> (signal 'end-of-file nil))))
