What needs to be done to update lablst.sty?

Question

This question is related to the question How to get a list of all the labels in a LaTeX document. According to the author of lablst.sty, you can use lablst as a global option to documentstyle as \documentstyle[11pt,lablst]{article} to produce (a list of) label definitions at the end of the document.

Can this be updated so that it can be used with documentclass?

Answer 1

You can try with this newlablst.sty to be called by \usepackage{newlablst}:

\RequirePackage{atveryend,ltxcmds}
\AtVeryEndDocument{\@lablst}
\def\@lablst{
  \parindent 0pt \parskip 0pt
  \normalsize
  \newwrite \labfile \relax
  \immediate\openout \labfile =\jobname.lab\relax
  {\def\toc{toc}
   \def\@writefile##1##2{\def\temp{##1}%
     \ifx\temp\toc
       \immediate\write\labfile{\unexpanded{##2}}%
     \fi}
   \def\newlabel##1##2{\immediate\write\labfile{\string\newlabel{##1}{##2}}}
   \def\bibcite##1##2{\immediate\write\labfile{\string\bibcite{##1}{##2}}}
   \makeatletter
   \input \jobname.aux }
   \immediate\closeout\labfile
   \def\newlabel##1##2{\par \hbox to \textwidth
     {\hfill\makebox[10em][l]{\ttfamily ##1}\makebox[3.5em][l]{\first 
      ##2}\hspace{1em}Page:\makebox[3em][r]{\second ##2}\hspace{4em}}}
   \ltx@ifpackageloaded{hyperref}
     {\def\first##1##2##3##4{##1}\def\second##1##2##3##4{##2}}
     {\def\first##1##2{##1}\def\second##1##2{##2}}
   \def\bibcite##1##2{\par\makebox[2in][l]{\ttfamily ##1}[##2]\par}
   \input \jobname.lab
   \clearpage
}

EDIT

This is perhaps a more robust version; it's just the more modern lablst.tex:

\RequirePackage{atveryend,ltxcmds}
\def\@lablst{%
  \ltx@ifpackageloaded{hyperref}
    {\long\def\x@firstoftwo##1##2##3##4{##1}%
     \long\def\x@secondoftwo##1##2##3##4{##2}}
    {\long\def\x@firstoftwo##1##2{##1}%
     \long\def\x@secondoftwo##1##2{##2}}
  \let \@mlabel \@gobbletwo
  % No protection needed:
  % 
  \let \protect \relax
  % Better formatting?:
  % 
  \let \raggedright  \relax
  % Only write out toc entries:
  % 
  \def \@writefile ##1##2{%
    \def\lablst@tempa{##1}%
    \def\lablst@tempb{toc}%
    \ifx \lablst@tempa\lablst@tempb
      \par{##2}\par\nobreak
      \vspace{3pt}%
    \fi
  }
  % Allow characters like ^ _ to be printed `verbatim'.
  %
  \def\@lablstverb##1{%
    \def\lablst@tempa{##1}%
    {\ttfamily\expandafter\strip@prefix\meaning\lablst@tempa}}%
  % For first run:
  % 
  \def \newlabel ##1##2{%
    \par
    \hbox to \textwidth{%
      \hfill\makebox[10em][r]{\@lablstverb{##1}}%
      \hspace{1em}\makebox[4.5em][l]{\x@firstoftwo ##2}%
      Page:
      \makebox[2.5em][r]{\x@secondoftwo ##2}%
      \hspace{4em}}\par
  }
  \let \bibcite \@gobbletwo
  {\Large \sl Logical labels within sections}
  \input{\jobname.aux}
  % For second run:
  % 
  \def \bibcite ##1##2{\par
    \hbox to \textwidth{%
    \hfill\makebox[2in][r]{\@lablstverb{##1}}\hspace{1em}[##2]\hspace{4em}}}
  \let \newlabel \@gobbletwo
  \let \@writefile \@gobbletwo
  \par
  \vspace{2\baselineskip}
  {\Large \sl Bibliography logical labels} 
  \input{\jobname.aux}\clearpage
}

This seems to works also with hyperref.
