How to set two types of appendixes on memoir class?

Question

I need to set up two types of appendixes: Appendixes and Annexes

They must appear as "Appendix A - Title of Appendix A", etc, and "Annex A - Title of Annex A", etc. in the chapter head (which I managed to do with a \renewcommand{\appendixname}{Annex}.)

I also need that they appear that way in the table of contents... but a \renewcommand{\cftappendixname}{Annex} works globally...

Answer 1

My browser does not like the forms on this site, so I'll answer here.

\cftinserthook{toc}{AAA}

inserts a hook command into the toc file at the time where the command is placed in the document. The corersponding hook code does not need to be defined, if not it is silently ignored.

In our case we could simply define the hook in the preamble as

\cftinsertcode{AAA}{\renewcommand*{\cftappendixname}{Annex}}

The nice thing about this is that then one does not need to worry about \protect

Answer 2

This sort of thing is often awkward, because you need the change to occur while \tableofcontents is doing its work. A dirty trick is to put the command that changes the appendix name used by the table of contents inside the .toc file.

\documentclass{memoir}
%
\makeatletter
\newcommand\@switch[1]{ \@writefile{toc}{\renewcommand*{\cftappendixname}{#1 \space}} }
\newcommand{\switchchapname}[1]{ \protected@write \@auxout {}{\string\@switch{#1} }}
\makeatother
%
\begin{document}
\renewcommand*{\cftappendixname}{Appendix \space}
\tableofcontents
\chapter{A chapter}
text.
\appendix
\chapter{An appendix}
more text.
\switchchapname{Annex}% Corrected from \switchapname → \switchchapname
\renewcommand{\appendixname}{Annex}
\chapter{An annex}
Yet more text.
\switchchapname{Another name}% Corrected from \switchapname → \switchchapname
\renewcommand{\appendixname}{Another name}
\chapter{Something else}
Yet more text.
\end{document}
