%% This package was invented by Jeffrey P. Goldberg.
%% I thought that an enhancement was needed and therefore created the pageslts package,
%% https://ctan.org/pkg/pageslts. Nevertheless, for compatibility with existing
%% documents/packages as well as for the low amount of resources needed by the
%% lastpage package (no new counter!), I updated this package.
%% Thanks go to Jeffrey P. Goldberg for allowing me to do this.
%% 
%% While this package allows for things like "Page slash thepage{} of slash pageref{LastPage}"
%% to get "Page 7 of 9" or "Page VII of IX",
%% the NUMBER of pages is nowadays available from the kernel
%% (slash @abspage@last, slash thetotalpages, slash PreviousTotalPages),
%% but with pages for example I to X and then 1 to 10, the number of pages would be "20",
%% while the name of the last page is "10". Decide what you need/want!
%% 
%% This work consists of the main source file lastpage.dtx,
%% the README, and the derived files
%%    lastpage.sty, lastpage209.sty, lastpage2e.sty,
%%    lastpageclassic.sty, lastpagemodern.sty,

This example demonstrates the use of package\newline
\textsf{lastpage}, v2.1h as of 2025-08-14 (HMM; JPG).\newline
The package takes no options.\newline
For more details please see the documentation!\newline

\noindent \label{keys} To hide the \pageref{keys}{\qquad } use option
\texttt{final} instead of \texttt{draft} with the \textsf{showkeys}
package (or remove the package call from the preamble of
this document).\newline

\textbf{Hyperlinks or not:} If the \textsf{hyperref} package is loaded,
the references are also hyperlinked:\newline
\smallskip
Last page's name (LastPage): \pageref{LastPage}\newline
\noindent If the \textsf{hyperref} package is loaded, but the hyperlinks
of the references shall be suppressed, \verb|\pageref*{...}|
can be used:\newline
\smallskip
Last page's name (LastPage): \pageref*{LastPage}\newline

\textbf{Trademarks} appear throughout this example without any
trademark symbol; they are the property of their respective
trademark owner. There is no intention of infringement; the
usage is to the benefit of the trademark owner.\newline

\textbf{Tip}: Use \textit{logical page numbers}
for the display of the pdf (in Adobe Acrobat Reader 2024.005.20392:
Edit $>$ Preferences $>$ Page Display $>$
Page Content and Information: Use logical page numbers)!\newline

If you are more ambitious in respect to your aims with this package,
you might want to have a look at the \textsf{pageslts} package:\newline
\url{https://ctan.org/pkg/pageslts}.
\bigskip

\noindent The page (\verb|\thepage|): \thepage \newline
Last page's name (LastPage): \pageref{LastPage}
\newpage

\noindent The page (\verb|\thepage|): \thepage \newline
Last page's name (LastPage): \pageref{LastPage}

\bigskip

\noindent There was the question:

\begin{quote}
\begin{verbatim}
\documentclass{article}
\usepackage{hyperref}
\usepackage{lastpage}
\begin{document}
\ifnum\thepage=\pageref{LastPage} foo \else bar \fi
\end{document}
\end{verbatim}

producing the error
\textquotedblleft missing number, treated as zero\textquotedblright.
\end{quote}

\noindent \verb|\pageref| inserts a hyperlink, \verb|\pageref{LastPage}|
is not expandable and the code breaks.\newline
The code does not generally work even without hyperref.

\begin{quote}
\begin{verbatim}
\documentclass{article}
\usepackage{hyperref}
\usepackage{lastpage}
\pagenumbering{Roman}
\begin{document}
\addtocounter{page}{8}
\edef\here{\thepage}
\makeatletter
\ifx\here\lastpage@lastpage\relax foo\else bar\fi
\makeatother
\end{document}
\end{verbatim}
\end{quote}

\noindent does work (two compilations needed), because \verb|\lastpage@lastpage|
contains the name of the page, \mbox{example:}
\begin{verbatim}
Page \thepage{} is (not) page
\makeatletter\lastpage@lastpage\makeatother.
\end{verbatim}
prints:\newline
Page \thepage{} is (not) page
\makeatletter\lastpage@lastpage\makeatother.
\newline
This can be broken for example by \verb|\pagenumbering{fnsymbol}|
(because then \verb|\edef\here{\thepage}| does not work).
\newpage

\noindent The page (\verb|\thepage|): \thepage\newline
Last page's name (LastPage): \pageref{LastPage}
\bigskip

With modern \LaTeX{} it is possible to say:
\begin{quote}
\begin{verbatim}
\NeedsTeXFormat{LaTeX2e}[2024-11-01]
\documentclass{article}
\pagenumbering{fnsymbol}
\begin{document}
\addtocounter{page}{8}%
\ExplSyntaxOn%
\xdef\test{\numexpr\the\g_shipout_readonly_int +1\relax}%
\ExplSyntaxOff%
\ifnum\PreviousTotalPages=\test\relax%
This is the last page.%
\else%
This is not the last page
(or it is but \LaTeX{} needs another compilation run
to detect this).
\fi
\end{document}
\end{verbatim}
\end{quote}

\newpage
\section*{The End}
\noindent The page (\verb|\thepage|): \thepage \newline
Last page's name (LastPage): \pageref{LastPage}
\bigskip

To see the content of the \texttt{enddocument/afterlastpage}-hook
(for a recent \LaTeX-format!) use % without the \verb||, of course!
\verb|\ShowHook{enddocument/afterlastpage}|.
\end{document}
