Text Formatting ⇒ verbatim | Verbatim Environment causes critical Errors

[Puppy]

Hi, this is my first post regarding LaTeX problems. If I forgot to include any important information please ask so I can provide it.

My problem has to do with the verbatim and the listing packages. I use MiKTeX 2.9 with TechnicCenter RC1 stable version.

My document looks like this:

Code: Select all

\documentclass[a4paper,12pt]{article}
\usepackage{a4wide}%papierrand
\usepackage{graphicx}
\usepackage{graphics}
\usepackage{german}
\usepackage{float}
\usepackage[latin1]{inputenc}%latin1 inputenc gibt das ß und die umlaute her
\usepackage{amsmath}%formelnumerierungen und anordnungszeugs
%\usepackage[Ausrichtung]{floatflt}%bilder mit text umzu
\usepackage[T1]{fontenc}
\usepackage{url}
\usepackage{subfigure}
\usepackage{setspace} %1.5 facher zeilenabstand
\onehalfspacing				%1.5 facher zeilenabstand
\usepackage[left=3cm,right=3cm,top=2cm,bottom=2cm]{geometry}
\def\bra#1{\ensuremath{\langle{#1}\vert}}
\def\ket#1{\ensuremath{\vert{#1}\rangle}}
%\usepackage{hyperref}
\usepackage{url}
\usepackage[pdffitwindow=true, pdftex]{hyperref}
\usepackage{color}
%\usepackage{listings}	
\usepackage{verbatim}
\begin{document}

...
\input{bla.tex}
.
.
.
\input{appendix.tex}
\end{document}

In the appendix.tex is a verbatim environment which I want to use since listings produce only errors with any kind of matlab code I want to include. none of the errors are known anybody else. So i though ok screw you nicely formated text, you will be just black and white. and now this:

-appendix.tex-

Code: Select all

\begin{verbatim}

%opa129u

plot(1:length(dat),dat(:,2)*10^3)

n=0
for i=1:600:length(dat(:,2))
    n=n+1;
    if i+1200>=length(dat(:,2)) break
    end
drift(n)=mean(dat(i+600:i+1200,2))-mean(dat(i:i+600,2));
end

std(dat2(:,2))
rms=sqrt(sum((dat2(:,2)-mean(dat2(:,2))).^2)/length(dat2))
n=0
for i=1:600:length(dat2(:,2))
    n=n+1;
    if i+1200>=length(dat2(:,2)) break
    end
drift(n)=mean(dat2(i+600:i+1200,2))-mean(dat2(i:i+600,2));
end
figure
plot([1:length(drift)],10^6*abs(drift),'-o');
set(gca,'FontSize',14)
title('Drift des Femt- DLCPA 200 bei eienr Verstärkung von 10^9 V/A')

print('-djpeg100','../Bilder/driftfemto.jpg');

%drift

	\centering
		\includegraphics[width=0.80\textwidth]{../Bilder/platzhalter.jpg}
	\caption{Platzhalter Strom abstandskurve}

\end{figure}

this code works fine - 0 errors - however this is not the code I want to present. If I modify this code to:

-appendix.tex-

I get this errors:

I've inserted a begin-math/end-math symbol since I think
you left one out. Proceed, with fingers crossed.

you can ask a wizard to enlarge me.

I have no idea why I tried to fix this for three days now. I hope anybody can help me.

The error appears next to where you've written

Code: Select all

ylabel('Drift in µV/min')

Since this doesn't appear in the code that's working it's a good guess that this the one causing the trouble. I would especially think that the µ causes the problems.

Indeed can the error be reproduced with this minimal working example:

Code: Select all

\documentclass{article}
\usepackage[latin1]{inputenc}
\begin{document}

\begin{verbatim}
 ylabel('Drift in µV/min')
\end{verbatim}

\end{document}

A similar code with utf8 encoding works nicely, though:

Code: Select all

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{textgreek}
\usepackage{newunicodechar}
\newunicodechar{µ}{\textmu}
\begin{document}

\begin{verbatim}
 ylabel('Drift in µV/min')
\end{verbatim}

\end{document}

I guess that changing the encoding of your source would cause more trouble than solve anything but unfortunately I don't know enough about encodings to be able to help you. Maybe someone else has an idea?

Clemens already pointed out the source of the error. And it can be fixed amazingly simple by loading the textcomp package.

While this is working for the verbatim package, it doesn't neither with listings nor with its extension listingsutf8 (from the oberdiek bundle).

If you want your listings to have nice syntax highlighting, you can use the minted package as a possible alternative. Tips on how to make it work are given in the forum [1]. For a detailed description of its capabilities refer to the package manual. A small example based on your code (see attachment).

Code: Select all

\documentclass[11pt,a4paper,ngerman]{article}
\usepackage[T1]{fontenc}
\usepackage{selinput}
\SelectInputMappings{
  adieresis={ä},
  germandbls={ß},
  Euro={€}
}
\usepackage{babel}
\usepackage[hmargin=3cm,vmargin=2cm]{geometry}
\usepackage{minted}
\usepackage{textcomp}

\begin{document}
  \inputminted[linenos,fontsize=\footnotesize]{matlab}{drift.m}
\end{document}

For more clarity I swapped the actual Matlab code into an external file (see attachment). Line 30 of the Matlab code is a bit problematic because due to missing blank spaces it cannot be wrapped.

Finally some remarks regarding the code you presented.

• The a4wide package is obsolete. It isn't needed here anyway because you pass the a4paper option to the document class and use the geometry package.
• The subfigure package is obsolete. Use its direct successor subfig or a more sophisticated package.
  • floatrow
  • subcaption (from the caption bundle)
• The german package is obsolete. For documents in German replace it with babel along with the ngerman language option (in my example given globally to the document class so that other packages may benefit).
• The setspace package can be directly loaded with a corresponding option for the desired line spacing.

  Code: Select all

  \usepackage[onehalfspacing]{setspace}

• You only need to load the graphicx package, which in turn loads graphics.
• Replace color with the more sophisticated xcolor.
• Use float with caution.
• Think about using the braket package.
• Think about using a class from the KOMA-Script bundle.

For details and a deeper understanding of their capabilities refer to the respective manuals of the involved packages.

Wow. Do you know what textcomp does to fix this? Defining the right symbol for µ, I suppose...

I've never heard of listingsutf8 before. A nice one, even if only \lstinputlisting is patched.

[localghost]

Wow. Do you know what textcomp does to fix this? Defining the right symbol for µ, I suppose... […]

That's correct. The package just supports the Text Companion fonts by providing corresponding symbols. In this case it's \textmu that makes the difference.

Wow, thanks for the help. Yes the µ made problems. Now without it, even nicely colored code is archiveable. Thank you guys very much.
