Hello,

A colleague of mine writes an article for a journal. The style guide for
sections and subsections in the appendix is like

APPENDIX A: Title
1. Subtitle for A

He managed to get the uppercase APPENDIX and the colon and final dot.
But now the references look bad (like see B: or see 1.. at the end of a
sentence). I found some approaches, but couldn't make them work.

https://tex.stackexchange.com/a/413816
https://tex.stackexchange.com/q/22435 (first two answers)

The document with the bad references is below. It would look better if
the colon and the dot would not appear in the references. Any help is
appreciated.

Holger

For reference: Sometimes the solution is making it more simple. :-)
Removing the package appendix and just using \appendix and changing
\appendixname solves the problem (see changes in the example below).

Each section command writes to the .aux file a \newlabel command to
create the reference. Maybe you could redefine this command to remove
the trailing colon. Something like that (not tested!!) :

\makeatletter
\newcommand*\org@newlabel{}
\let\org@newlabel\newlabel
\renewcommand*\newlabel[2]{{\def\@tempa##1##2##3##4##5{\count0=#2
\def\@tempb{{##3}{##4}{##5}}%
}%
\@tempa#2%
\edef\@tempa{\noexpand\org@newlabel{#1}{{APPENDIX \@Alph\count0}{\the\count0}\@tempb}}%
\expandafter}\@tempa
} \makeatother

This way seems to work:

--------8<-----------8<-----------8<-----------8<-----------8<-------
% In preamble
\DeclareRobustCommand*\annexesecnumformatter[1]{ANNEXE #1:}% with colon
\makeatletter
\newcommand*\org@newlabel{}
\let\org@newlabel\newlabel
\renewcommand*\newlabel[2]{{%
\def\annexesecnumformatter##1{ANNEXE ##1}% w/o colon
\edef\@tempa{\noexpand\org@newlabel{#1}{#2}}%
\expandafter}\@tempa
} \makeatother

....
% In APPENDIX
\renewcommand*\thesection{\annexesecnumformatter{\Alph{section}}}
--------8<-----------8<-----------8<-----------8<-----------8<-------

Hello Vincent,

Thank you very much for the idea. This gives the desired result when
using the package appendix.

Full working example (with slight changes) is below.

Thanks again,
Holger
