Remove dots from appendix chapter numbering in KOMA-Script 3.34

Question

I would like to display the appendix chapter title as "Appendix A Appendixname" in the table of contents and "A Appendixname" in the text.

So far i get the right order of "A" and "Appendix" using \usepackage[titletoc]{appendix} but an unwanted dot gets printed (i.e. "Appendix A. Appendixname) in the toc.

Previously, one could alter appendix titleformats using the \appendixmore-trick, however this functionality seems to be depreached as of KOMA-Script 3.34 (see changelog). Unfortunately i don't know enough LaTEX to find a new solution with the information presented in the changelog.

My current code:

\documentclass{scrreprt}
\usepackage[titletoc]{appendix}
% appendixmore-trick (not working anymore)
\newcommand{\appendixmore}{%
  \renewcommand{\sectionformat}{\appendixname~\thesection\autodot\enskip}
  \renewcommand*{\sectionmarkformat}{\appendixname~\thesection\autodot\enskip}
}
\begin{document}
\tableofcontents
\chapter{Lorem ipsum}
\section{Dolor sit amet}
\appendix
\begin{appendices}
  \chapter{Consectetur adipiscing elit}
  \chapter{Mauris euismod}
\end{appendices}
\end{document}

This works apart from the unwanted dots:

Same for the chapter title:

Any help is appreciated :)

Answer 1

Your definition of \appendixmore will works with KOMA-Script version 3.34, too.

If LaTeX as of version 2021/06/01 is used with a KOMA-Script class

From changelog of version 3.34

• \appendix contains a LaTeX hook named <class>/appendix, where <class> is the name of the KOMA-Script class.
• This hook is executed before \appendixmore.
• Option appendixprefix (and headings=onelineappendix and headings=twolineappendix) is no longer implemented via \appendixmore, but via the LaTeX hook <class>/appendix.

So a user defined \appendixmore will be executed with KOMA-Script version 3.34, too. Additionally you can use \newcommand\appendixmore{...} even if you use one of the options appendixprefix, headings=onelineappendix or headings=twolineappendix.

Example:

\documentclass
  [appendixprefix=false]
  {scrreprt}
\newcommand{\appendixmore}{\renewcommand{\chapterformat}{This is \appendixname:\enskip}}
\begin{document}
\chapter{Foo}
\appendix
\chapter{Bar}
\KOMAScriptVersion
\end{document}

works with an uptodate KOMA-Script prerelease of version 3.34 and LaTeX as of version 2021/06/01. But with KOMA-Script version 3.33 or older you would get the error message »Command \appendixmore already defined.«, because the old KOMA-Script versions have defined this macro to implement the options appendixprefix etc.

---

The following example can be used with KOMA-Script version 3.33 or version 3.34. It removes the dot only from appendix chapters numbering and adds the prefix in ToC without an additional package:

\documentclass{scrreprt}
\newcommand{\appendixmore}{
  \renewcommand{\chapterformat}{\thechapter\enskip}%
  \renewcommand*{\chaptermarkformat}{\thechapter\enskip}%
  \addtocontents{toc}{\protect\appendixtocentry}%
}
\newcommand*{\appendixtocentry}{%
  \DeclareTOCStyleEntry[
    entrynumberformat=\appendixprefixfixintoc,
    dynnumwidth
  ]{default}{chapter}%
}
\newcommand{\appendixprefixfixintoc}[1]{%
  \def\autodot{}%
  \appendixname~#1%
}
\begin{document}
\tableofcontents
\KOMAScriptVersion
\chapter{Lorem ipsum}
\section{Dolor sit amet}
\appendix
\chapter{Consectetur adipiscing elit, Consectetur adipiscing elit, Consectetur adipiscing elit}
\chapter{Mauris euismod}
\end{document}

It is also possible to use the new hook provided by KOMA-Script version 3.34:

\documentclass{scrreprt}[2021-04-30]
\AddToHook{scrreprt/appendix}{%
  \AddToHook{cmd/chapterformat/before}{\def\autodot{}}%
  \AddToHook{cmd/chaptermarkformat/before}{\def\autodot{}}%
  \addtocontents{toc}{\appendixtocentry}%
}
\NewDocumentCommand{\appendixtocentry}{}{%
  \DeclareTOCStyleEntry[
    entrynumberformat=\appendixprefixfixintoc,
    dynnumwidth
  ]{default}{chapter}%
}
\NewDocumentCommand{\appendixprefixfixintoc}{m}{%
  \def\autodot{}%
  \appendixname~#1%
}
\begin{document}
\tableofcontents
\KOMAScriptVersion
\chapter{Lorem ipsum}
\section{Dolor sit amet}
\appendix
\chapter{Consectetur adipiscing elit, Consectetur adipiscing elit, Consectetur adipiscing elit}
\chapter{Mauris euismod}
\end{document}

But may be it is better to use a generic hook of command \appendix: cmd/appendix/after. It is executed at the very end of the command body of \appendix. Note \appendixmore - if defined - would be executed before this hook.

\documentclass{scrreprt}[2021-04-30]
\AddToHook{cmd/appendix/after}{%
  \AddToHook{cmd/chapterformat/before}{\def\autodot{}}%
  \AddToHook{cmd/chaptermarkformat/before}{\def\autodot{}}%
  \addtocontents{toc}{\appendixtocentry}%
}
\NewDocumentCommand{\appendixtocentry}{}{%
  \DeclareTOCStyleEntry[
    entrynumberformat=\appendixprefixfixintoc,
    dynnumwidth
  ]{default}{chapter}%
}
\NewDocumentCommand{\appendixprefixfixintoc}{m}{%
  \def\autodot{}%
  \appendixname~#1%
}
\begin{document}
\tableofcontents
\KOMAScriptVersion
\chapter{Lorem ipsum}
\section{Dolor sit amet}
\appendix
\chapter{Consectetur adipiscing elit, Consectetur adipiscing elit, Consectetur adipiscing elit}
\chapter{Mauris euismod}
\end{document}

The result is the same as above.

Answer 2

I found an answer to the problem:

Use the numbers=noenddot option of scrreprt to prevent trailing dots in the toc. In contrary to my initial plan, this removes all trailing dots throughout the numbering sceme of the document but i am actually happy with this.

\documentclass[numbers=noenddot]{scrreprt}

Secondly, as linked by schtandard, the format of the chapter title can be changed by overwriting \chapterformat right before the appendix. (See also KOMA-Script scrbook: How to remove period after part)

\renewcommand*{\chapterformat}{\appendixname~\thechapter~~}

Remember to change the command back to its original form if you want the following sections to be displayed in the usual way.
