bookmarkshyperref
I have a document that has many sections. I don't want section numbers to show up in the document, but I do want the sections to show up automagically as bookmarks in the PDF using the hyperref package.
I know I can use the \section* command to eliminate section numbers in the document, but this also removes the bookmark. Is there some sort of compromise?
Just set counter secnumdepth accordingly.
If the paragraph titles do not appear in the table of contents (counter tocdepth), then the depth can set to a different value for the bookmarks.
Full example:
\documentclass{article}
\usepackage{hyperref}
\usepackage{bookmark}
\bookmarksetup{
open,
numbered,
depth=5, % otherwise the setting of counter `tocdepth' would be used
}
\setcounter{secnumdepth}{2}
\begin{document}
\section{Section}
\subsection{Subsection}
\paragraph{Paragraph}
\subparagraph{Subparagraph}
\end{document}
Option addtohook of package bookmark allows to change the settings for a bookmark in dependence of some parameters such as the bookmark level.
Thus the following would solve the problem:
\bookmarksetup{
numbered,
addtohook={%
\ifnum\bookmarkget{level}>1 %
\bookmarksetup{numbered=false}%
\fi
},
}
Unhappily option numbered is evaluated before the hook in \bookmark is executed, see the definition of \Hy@writebookmark in package bookmark.
Thus the following example changes the effect of option numbered instead:
\documentclass[a4paper,12pt]{article}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage[atend]{bookmark}
\bookmarksetup{
open,
openlevel=2,
numbered,
addtohook={%
\ifnum\bookmarkget{level}>1 %
\DisableBookmarkNumbering
\fi
},
}
\makeatletter
\newcommand*{\DisableBookmarkNumbering}{%
\let\numberline\@gobble
% The followings are not needed for subsections and below
% \let\booknumberline\@gobble
% \let\partnumberline\@gobble
% \let\chapternumberline\@gobble
}
\makeatother
\begin{document}
\section{Bla bla}
...
\subsection{Lorem}
...
\subsection{ipsum}
..
\section{Bla bla bla}
\end{document}

You can just suppress the appearance of the section number:
The macro
\@seccntformatis responsible for printing the section number; by redefining it to "do nothing" the number is not printed, but hyperref is able to create the bookmark correctly.The bookmark package is a good add-on, as it avoids some weaknesses of the original implementation of bookmark creation.
