* 'listings' package used but not required in LaTeX export

Hi List, 

at the risk that this is caused by some personnal configuration I'm not
aware of at the moment, I report it nevertheless:

When I export an .org buffer with source code blocks (e.g. R) to LaTeX,
functions from the 'listings' package are used in the LaTeX sources,
like e.g. 

,---------------------------------
| \lstset{language=R,numbers=none}
| \begin{lstlisting}
`---------------------------------

but there is no 

,----------------------
| \usepackage{listings}
`----------------------

statement in the preamble. This is about exporting with no further
options or properties set, the default case so to say. 

PS
Emacs Version:
(24.3.1 24 3 gnu/linux hostname x86_64-unknown-linux-gnu x nil)

Org-mode version 8.0.3 (release_8.0.3-165-g60ca9e @
/home/tj/gitclone/org-mode/lisp/)

cheers,
Thorsten

This is a feature to my understanding.

Several packagess can format, and I for instance prefer pygments if I
need code formatting.

You could add listings to your packages list, either
org-latex-packages-alist or even org-latex-default-packages-alist, if
you really want to.

You could probably also write a clever filter to load a package if it
is missing.

When in doubt, do it!

mmhh ... I would rather say that the defaults can be as simple as
possible (or desired), but should result in reasonable output without
any user interaction. But without adding a \usepackage{listings} or
modifying the variables you mention the LaTeX output is unusable in this
case.

Then the default should be loading one of them rather than using package
macros in the exported LaTeX sources without loading a package that
contains those macros.

I could, and thanks for the tips, but I still think this can be
considered a bug (if I'm not the only one having the problem).

By default, `org-latex-listings' is nil, which means no "listings" code
is inserted in the output. Therefore, the problem comes from your
configuration (i.e. you changed variable's value without reading its
docstring).

Ok, thanks to both of you, knowing what to search for I found the entry
in my init file and adapted my settings such that 'listings' are enabled
_and_ the package is loaded by default.
