LaTeX forum ⇒ LyX ⇒ Alpha-numerical chapters Topic is solved

[aerus]

Hello,

I try to use LyX to write my german law thesis. If I add chapters and sections, I get a structure like I, 1, 1.1 what I want is though: A, I, 1, a), aa, (i), (ii)

Is it possible with LyX? If yes, how?

Thank you in advance

Hi Aerus,

welcome to the board!

You could place LaTeX redefinitions in your LyX document preamble for that.

\renewcommand*{\thechapter}{\Alph{chapter}}
...
\renewcommand*{\thesubsubsection}{(\roman{subsubsection})}

Have a look at Manipulating the way counters are printed to learn more about that.

Thanks for your rapid reply.

If I set this into preamble, I get this error message:

LaTex Error: \thechapter undefined

What can it be?

[Stefan Kottwitz]

Obviously you use a document class which doesn't provide chapters, such as article. Or which one did you choose?

Ok, thanks, I figured it out now. I have another question. My TOC looks now like in the attachment.

I don't need the spacing between the number and the caption. How can I change this, too?

[Stefan Kottwitz]

Perhaps post your settings here, or the LyX preamble, as attachment. We cannot see yet how you produce that space or which settings cause that.

I use article with KOMA-Script. My preamble looks like this:

\renewcommand*{\thepart}{\Alph{part}}
\renewcommand*{\thesection}{\Roman{section}}
\renewcommand*{\thesubsection}{\arabic{subsection}}
\renewcommand*{\thesubsubsection}{\alph{subsubsection}}
\renewcommand*{\theparagraph}{\roman{paragraph}}
\renewcommand*{\thesubparagraph}{(\arabic{subparagraph})}

[Stefan Kottwitz]

Ok, let's make a minimal working example, with your settings and class:

\documentclass{scrartcl}
\renewcommand*{\thepart}{\Alph{part}}
\renewcommand*{\thesection}{\Roman{section}}
\renewcommand*{\thesubsection}{\arabic{subsection}}
\renewcommand*{\thesubsubsection}{\alph{subsubsection}}
\renewcommand*{\theparagraph}{\roman{paragraph}}
\renewcommand*{\thesubparagraph}{(\arabic{subparagraph})}
\begin{document}
\tableofcontents
\section{Section level}
\subsection{Subsection level}
\subsubsection{Subsubsection level}
\subsubsection{Subsubsection level}
\paragraph{Paragraph level}
\end{document}

You will get the default look, which reserves space for wider numbers, because numbering such as I.1.a. is expected.

Now let's load tocstyle. It belongs to KOMA-Script, which you have installed, and provides an option for automatically calculating the indentation in the toc.

\usepackage[tocindentauto]{tocstyle}

It will calculate during several LaTeX compiler runs, then it will finally look this way:
