LyX ⇒ Altered Heading Numbers

[tompv]

Hi,

I am working on an article in LyX (version 2.0.6). Sections are automatically numbered in Arabic numerals and sub-sections accordingly.

I would need to change this: Sections should be numbered in Roman numerals. Sub-sections should be numbered alphabetically (e.g. what are automatically numbered as section 2 and subsection 2.1. should rather become section II and subsection A).

Should it be possible to fix this by means of the menu-bars, that would be even easier as I'm not too comfortable with the actual coding options.

Thanks in advance for you advice!

I do not use Lyx and have no idea how to implement what you want by means of menu bars. But it is very simple to get what you want by just entering a couple of lines into the preamble of your document. Here is a minimal working example for what you want.

Code: Select all

\documentclass{article}

\renewcommand{\thesection}{\Roman{section}}
\renewcommand{\thesubsection}{\thesection.\Alph{section}}

\begin{document}

\section{Intro}

\subsection{Blah}

\section{Intro2}

\subsection{Blah blah}

\end{document}

Thanks very much.

I'm sure I must be doing something wrong, but nothing changes when I enter this into the LaTeX preamble in LyX (also not in case I open a new document)...

Whenever you enter anything in the preamble you cannot count on LyX understanding it. So always check in the compiled PDF. If you want LyX to understand it you need to read about layouts and modules. See Help > Customization.

Thanks

So, in putting the two together, I have added the code provided by mas in the local layout (rather than directly in the LaTeX preamble), as suggested by scottkosty. When adding the "Preamble" and "EndPreamble" commands at the beginning and end, respectively, the "valid layout!" message appears. Yet, nothing actually changes (in a given document) or appears (in a blank document). Thanks for your patience --- I think we're getting close

At this point, I feel it is more a LyX question than a LaTeX question Hopefully LyXers around here might help you.

Hi,

On the TeX forum, they gave me the following solution, which works:
"To get the result you ask for, add

\renewcommand\thesection{\Roman{section}}
\renewcommand\thesubsection{\Alph{subsection}}

to the preamble."

Thanks and best.
