是否可以使用 ntheorem 的标题自动创建 PDF 书签?
例子:
\documentclass[a4paper]{scrartcl}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[hyperref]{ntheorem}
\usepackage{lipsum}
\usepackage{hyperref}
%ntheorem
\makeatletter
\renewtheoremstyle{break}%
{\item[\rlap{\vbox{\hbox{\hskip\labelsep \theorem@headerfont
##1\ ##2\theorem@separator}\hbox{\strut}}}]}%
{\item[\rlap{\vbox{\hbox{\hskip\labelsep \theorem@headerfont
##1\ ##2:\ ##3\theorem@separator}\hbox{\strut}}}]}%
\makeatother
\theoremstyle{break}
\theoremheaderfont{\normalfont\bfseries\large}
\theorembodyfont{\normalfont}
\theoremseparator{\medskip}
\theorempostskip{\topsep\medskip}
\newtheorem{exercise}{Exercise}
\begin{document}
\begin{exercise}[Lorem]
\lipsum[10]
\end{exercise}
\begin{exercise}[Ipsum]
\lipsum[10]
\end{exercise}
\end{document}
我想要为每个练习环境创建一个书签。
在此示例中,书签应称为“练习 1:Lorem”和“练习 2:Ipsum”。因此一般为“练习 n:名称”。
不一定非要使用 hyperref,我不介意使用其他包。
答案1
- 启动宏
\exercise
被修补以捕获可选参数。 hyperref
已经为编号练习设置了锚点。书签直接使用此锚点。- 添加了软件包
bookmark
以实现上一点。此外,书签的更新速度也更快。
