Is it possible to print the index numbers which are referring to a code line number instead of a page in typewirter font.

I know that I can change \main, but on this way I can’t change the format of the auto indexed commands.


% \iffalse



% \fi
% \DoNotIndex{\newcommand}
% \section{Usage}
% \DescribeMacro{\test} This is a stupid example
% for \cmd{\test}, but it prducec the right index
% formatting.
% \StopEventually{\PrintIndex}
% \section{Implementaion}
% \begin{macro}{\test}
% This is how Test is defined
%    \begin{macrocode}
\newcommand{\test}{Some text}
%    \end{macrocode}
% \end{macro}
% \begin{macro}{\supertest}
% And here \cmd{\test} is used in another macro
%    \begin{macrocode}
\newcommand{\supertest}{\test{} without sense}
%    \end{macrocode}
% \end{macro}
% \Finale

build with

pdflatex example.dtx
makeindex -s gind.ist -o example.ind example.idx
pdflatex example.dtx



But it should be
\test . . . . . . 1,1,2
(with 1 underlined)

You may try


after loading the class.

Indeed, in the index writing process, the class uses directly \number\c@CodelineNo, so this should work.

Writing also


will use typewriter type for the line numbers in the index, but consecutive line numbers will not be printed correctly (they form a unique link, so also the comma will be printed in typewriter type). This can be cured by calling makeindex with the -r option (that disables page ranges formation).

I tried it, but the font change affects only the line numbering in the implementation part but not the numbers in the index. – Tobi Sep 20 '11 at 12:36
This seems to be quite difficult to solve. :( – egreg Sep 20 '11 at 13:19
My idea was to find the lines in doc.sty that generate the entry and change them to add |texttt but I failed to find these lines … – Tobi Sep 20 '11 at 13:35
Unfortunately doc and hypdoc don't use the standard \index command, but do their own writing. – egreg Sep 20 '11 at 14:17
And can we (or better: you …) hack/patch into it? Could you please point me the relevant lines, so I can have a look myself. – Tobi Sep 20 '11 at 15:09
