TeX - LaTeX Asked by Frank Wilson on March 25, 2021
I am trying to define my own document class with some lead-in style heading text and pdf bookmarks.
Here is my class file myclass.cls:
NeedsTeXFormat{LaTeX2e}
ProvidesClass{myclass}
LoadClass[12pt,oneside,a4paper]{article}
makeatletter
% disable section numbering
setcounter{secnumdepth}{-2}
% define lead-in section
renewcommandsection{
@startsection{section}{1}{z@}{-1ex}{-1.5ex}{bfseriesMakeUppercase}%
}
RequirePackage{hyperref}
hypersetup{bookmarksdepth=4}
makeatother
And here is my document source mydoc.tex:
documentclass{myclass}
usepackage[english]{babel}
usepackage{blindtext}
begin{document}
section{First Section}
blindtext[5]
section{Second Section}
blindtext[5]
section{Third Section}
blindtext[5]
end{document}
If I compile this with pdflatex I get the following warnings:
pdfTeX warning (dest): name{section*.
3} has been referenced but does not exist, replaced by a fixed one
pdfTeX warning (dest): name{section*.2} has been referenced but does not exist,
replaced by a fixed one
pdfTeX warning (dest): name{section*.1} has been referenced but does not exist,
replaced by a fixed one
And pdf bookmarks do not go to their respective heading with clicked in the pdfviewer.
If the renewcommand below the comment % define lead-in section is removed. The bookmarks work fine (but then I won’t have the heading style I was looking for. I’d strongly prefer to keep the automatic section labelling/bookmarking if possible. Any ideas on how this can be achieved?
Probably you can use the MakeUppercase-variant of the textcase-package and patch its underlying @uclcnotmath-command to prevent case-changing also with Hy@SectionAnchorHref, which, when hyperref is loaded, creates anchors/named destinations of sections:
documentclass[12pt,oneside,a4paper]{article}
usepackage[overload]{textcase}
usepackage{etoolbox}
makeatletter
patchcmd{@uclcnotmath}%
{@nonchangecaseensuremath}%
{@nonchangecaseensuremath@nonchangecaseHy@SectionAnchorHref}%
{message{!!! Patching successful !!!}}%
{message{!!! Patching failed !!!}}%
makeatother
setcounter{secnumdepth}{-2}
makeatletter
renewcommandsection{%%%%
@startsection{section}{1}{z@}{-1ex}{-1.5ex}{bfseriesMakeUppercase}%
}
makeatother
RequirePackage{hyperref}
hypersetup{bookmarksdepth=4}
usepackage[english]{babel}
usepackage{blindtext}
begin{document}
section{First Section}
blindtext[5]
section{Second Section}
blindtext[5]
section{Third Section}
blindtext[5]
end{document}
