I think you guys are going down the wrong track.<br><br>On Tuesday, November 8, 2011, Marius Hofert &lt;<a href="mailto:marius.hofert@math.ethz.ch">marius.hofert@math.ethz.ch</a>&gt; wrote:<br>&gt; I just figured out that if I start emacs from the Mac&#39;s terminal (via &quot;emacs&quot; which starts /Applications/Emacs.app/Contents/MacOS/Emacs) and open an emacs shell with M-x shell, I can tab-complete a2ps.<br>
&gt;<br>&gt; Hmmm... so the GUI version seems to act weird...<br><br>It sounds to me like OSX&#39;s launcher is not setting some environment variable that does get set when you run the terminal.  Possibly $FPATH.  I would guess that it&#39;s looking for and not finding a function called _a2ps to do the completion.<br>
