Labels – Comprehensive List of All Labels with Hyperlinks in LaTeX

Question

I'm writing a document with several \label{} environments and I'm looking for an opportunity to generate a list of all of them at the beginning, something like this:

Label 1 ..... 1
Label 2 ..... 2
Label 3 ..... 4

And so on. I had a look at tocloft but couldn't find anything.

Answer 1

The label information is all in the aux file, so you can extract it something like this:

\documentclass{article}

\usepackage{hyperref}

\long\def\findlabel#1#2\findlabel{%
 \ifx\newlabel#1\lablist\expandafter{\the\lablist\showlabel#2}\fi}

%hyerref has 4 felds in each label culd use them but don't here
\def\showlabel#1#2{%
\par \noindent Label: \texttt{\detokenize{#1}}\dotfill \ref{#1} on page \pageref{#1}}

\newtoks\lablist
\newread\zz
\immediate\openin\zz=\jobname.aux
\loop
\ifeof\zz\else
\read\zz to \tmp
\expandafter\findlabel\tmp\relax\findlabel
\repeat
\begin{document}

\section*{Labels}

\the\lablist
