Subject: org-babel: [PATCH] allow emacs-lisp results to be pretty-printed
Date: Sat, 03 Oct 2009 20:29:15 +0200	[thread overview]
Message-ID: <87r5tkqqkk.fsf@in-ulm.de> (raw)

Hey there,

on irc (#org-mode) someone asked how one would go about to insert the
result of a emacs-lisp function without it being transformed into a
org-mode table.

I didn't see any other way, so I wrote a small patch that allows the
parameter :results to accept 'pp'. Is this the right way? And where
should this special parameter be documented?
