[O] How to prevent tabs from turning into spaces in source-code export?

[James Harkins]

I have (where TAB is a tab character):

#+BEGIN_SRC {}
// SuperCollider code here

(
r = p.chan.play(Pspawner { |sp|
TABvar num, subdiv,
...
});
)
#+END_SRC

The exported .tex file contains:

\begin{lstlisting}
// SuperCollider code here

(
r = p.chan.play(Pspawner { |sp|
spcspcspcspcspcspcspcspcvar num, subdiv,
...
});
)
\end{lstlisting}

I do not want this conversion to happen. If it doesn't happen, then I
can use listings' tabsize property to control the tab width.

Failing that, how do I tell org to use fewer than 8 spaces? The tabs
are much much too wide in the resulting pdf.

Try to preserve indentation:

  #+begin_src {} -i
  ...
  #+end_src

Hi Nicolas,

as indentation might be provided by TAB and whitespace chars likewise, what 
about following setting of `indent-tabs-mode'?

Best,

Andreas

It is indeed possible to propagate `indent-tabs-mode' value to the
original buffer's copy where export happens, but it will not be enough
to guaranty that indentation related TAB characters are preserved (e.g.,
if relative indentation falls below `tab-width' value although global
one was above).

The only way to make sure TAB will be preserved is to set
`org-src-preserve-indentation' to a non-nil value (or, locally, to use
-i switch).
