Problems with source code listings in PDF

Problems with source code listings in PDF

[Avdi Grimm]

[-- Attachment #1: Type: text/plain, Size: 973 bytes --]

I'm working on creating a PDF eBook with Org-Mode, and I'm running
into some difficulty getting them to come out looking decent.

I've followed the directions I found in the list archives for
outputting colorized source code listings. I set
org-export-latex-listings to t, and customized
org-export-latex-packages-alist according to the directions in the
org-export-latex-listings docs.

I'm seeing a few problems with the output:

1. There is no color; only bolded keywords.
2. Listings are formatted in a not-very-well-rendered font with serifs
that just doesn't look good at all.
3. In begin_example sections, spaces are replaced with odd little
curved underscores.

I've attached some examples to show what I mean.

I'm running Org-Mode 7.4 on Ubuntu 10.10 with Emacs 23.1.50.1.

Has anyone had any luck formatting source code and example listings in
PDF output? What I'd really like to get is output identical to the
listings exported to HTML.

Thanks!

I must admit that colour has never been something I've considered...
it is, however, an option for the listings package.

I've had no problems with typeface etc for listings in the past.

The use of curved underscores for spaces is deliberate and whether this
is done will depend on your source language.  You can customise this in
any case (see below).

In summary, you may need to add a line customising the listings
package.  Check out the user manual at

: ftp://ftp.tex.ac.uk/tex-archive/macros/latex/contrib/listings/listings.pdf

and then have something like this in your org file near the top:

#+latex_header: \lstset{showspaces=false, ...}

(replacing ... with the other options you may wish).

HTH.

add these definitions to the headers of the org file - they should
provide colour and a list of other things you can customize - these are
not from me, I think they are from this list or from worg.

Instructions for setting up different fonts can be found here:

http://orgmode.org/worg/org-tutorials/org-latex-export.html#sec-14

Note that some of the fonts clash with the amssymb LaTeX package,  
which Org-mode loads by default.  You'll want to choose a font that  
doesn't clash, or configure Org-mode so the amssymb package isn't  
loaded.

All the best,
Tom

I think a better answer for point 2. might be a header line of


#+LaTeX_HEADER: \lstset{ basicstyle=\small\ttfamily }
