appendicescross-referencing
I followed How to refer Appendix in a paper? and tried to refer to an appendix in the main body of the text, but it shows Section 1 instead of Appendix A. Here is the source code.
\documentclass[twoside,12pt]{article}
\usepackage{cleveref}
\begin{document}
Refer to \cref{appendix} for more information.
\section{Conclusion}
Draw conclusions here.
\appendix
\section*{Appendix A} \label{appendix}
Some text.
\end{document}
How do I display the reference text as Appendix A?
In my master document I have (in TeXnicCenter):
\appendix
\input{Appendix1}
\newpage
\input{Appendix2}
etc. And in my Appendix documents (I am using article class):
\section{Name of the Appendix}
\label{sec:Appendix1}
And then it appears as Appendix A, Appendix B, etc. in the document and in the TOC.
2- You can use the restatable environment provided by thmtools.
1- Since the environment generates an anchor, you can use the standard \label, \ref (\pageref) mechanism for cross-referencing.
A complete example:
\documentclass{article}
\usepackage{amsthm}
\usepackage{thmtools, thm-restate}
\usepackage{hyperref}
\declaretheorem{theorem}
\begin{document}
\section{Test Section}
\begin{theorem}
Test theorem
\end{theorem}
\begin{restatable}[Fundamental Theorem of Algebra]{theorem}{fta}
\label{thm:FTA}
Every non-constant single-variable polynomial with complex coefficients has at least one complex root.
\end{restatable}
\appendix
\section[Proof of the Fundamental Theorem of Algebra]{Proof of Theorem~\ref{thm:FTA} (See page~\pageref{thm:FTA})}
\fta*
\begin{proof}
Assume...
\end{proof}
\end{document}
Now that the question has been edited, and the used document class is known, here's a solution using the vldb document class (the link to the class can be found in the question):
\documentclass{vldb}
\usepackage{textcase}
\usepackage{thmtools,thm-restate}
\usepackage{hyperref}
\makeatletter
\def\@sect#1#2#3#4#5#6[#7]#8{%

\edef\@svsec{%

The problem is that vldb.cls sets the section (and also part) titles in upper case and uses the old TeX \uppercase command to this end; this will produce problems if special commands, such as \ref, are inside the argument of \section (or \part) since \uppercase don't recognize them as special commands and tretas them in the wrong way (the LaTeX command \MakeUppercase will also behave bad in this regard). To correct this situation, one can redefine (or patch) the internal command \@sect, to use \MakeTextUppercase (from the textcase package), instead of the problematic \uppercase command. In the example code above, the change was signaled with % HERE.
Best Answer
Here's a way to refer to starred sections (for the appendix, however!)
Redefine
\sectionto step a counter for the starred version as well -- this can be fed tocleverefwith appropiatecref-names.Alternatively, the command
\namereffromhyperrefpackage is clever enough itself to provide the correct name even for starred sections.Best, don't use starred sections here, this will remove the necessity of numbering them by hand.
