tikzmark 和 chappg 的兼容性

我在文档中使用tikzmark和时遇到了一个奇怪的问题：chappg

\documentclass{scrbook} 

\usepackage{chappg}
\usepackage{tikz}
\usetikzlibrary{tikzmark}

\begin{document}

\chapter{Test} 

foo\tikzmark{foo}

\vspace{2cm}

bar\tikzmark{bar}

\begin{tikzpicture}[overlay,remember picture]
   \draw (pic cs:foo) -- (pic cs:bar); 
\end{tikzpicture}

\end{document}

这得出

l.21    \draw (pic cs:foo)
                           -- (pic cs:bar);

      ! Missing number, treated as zero.

第二次运行时。如果我删除文件aux并在没有的情况下编译它chappg，则一切正常。为什么会这样？

正如 Stefan 提到的his answer，似乎有问题tikzmark；在

execute at end picture={%
\ifpgfrememberpicturepositiononpage%
\edef\pgf@temp{%
\noexpand\write\noexpand\pgfutil@auxout{%
\string\savepicturepage{\pgfpictureid}{\noexpand\thepage}}}%
\pgf@temp
\fi%
},

它使用\thepage，使用 更安全。下面是更正后的版本（的定义中\value{page}还有一个，但由于这里没有用到，所以这里不相关，不过它也应该被修改）：\thepage\pgfmark

\documentclass{scrbook} 

\usepackage{chappg}
\usepackage{tikz}
\usetikzlibrary{tikzmark}

\makeatletter
\tikzset{%
remember picture with id/.style={%
remember picture,
overlay,
save picture id=#1,
},
every picture/.append style={%
execute at end picture={%
\ifpgfrememberpicturepositiononpage%
\edef\pgf@temp{%
\noexpand\write\noexpand\pgfutil@auxout{%
\string\savepicturepage{\pgfpictureid}{\the\value{page}}}}%
\pgf@temp
\fi%
},
},
save picture id/.code={%
\immediate\write\pgfutil@auxout{%
\string\savepointas{#1}{\pgfpictureid}}%
},
if picture id/.code args={#1#2#3}{%
\@ifundefined{save@pt@#1}{%
\pgfkeysalso{#3}%
}{
\pgfkeysalso{#2}%
}
},
next page/.is choice,
next page vector/.initial={\pgfqpoint{0pt}{0pt}},
next page/below/.style={%
next page vector={\pgfqpoint{0pt}{-\the\paperheight}}%
},
next page/above/.style={%
next page vector={\pgfqpoint{0pt}{\the\paperheight}}%
},
next page/left/.style={%
next page vector={\pgfqpoint{-\the\paperwidth}{0pt}}%
},
next page/right/.style={%
next page vector={\pgfqpoint{\the\paperwidth}{0pt}}%
},
next page/ignore/.style={%
next page vector={\pgfqpoint{0pt}{0pt}}%
},
}
\makeatother


\begin{document}

\chapter{Test} 

foo\tikzmark{foo}

\vspace{2cm}

bar\tikzmark{bar}
\begin{tikzpicture}[overlay,remember picture]
   \draw (pic cs:foo) -- (pic cs:bar); 
\end{tikzpicture}

\end{document}

页码用于排序和引用标记位置。但是，chappg更改页码，例如从 1 更改为 1-1。会出现错误，因为那不再是一个数字。

您可以通过以下方式验证

\renewcommand*{\chappgsep}{0}

它将会起作用，因为它是数字。

无需进一步深入研究，我会说这是一个错误，因为它已经无法使用罗马页码：

\documentclass{scrbook} 
\usepackage{tikz}
\usetikzlibrary{tikzmark}
\pagenumbering{roman}
\begin{document}
foo\tikzmark{foo}

bar\tikzmark{bar}
\begin{tikzpicture}[overlay,remember picture]
   \draw (pic cs:foo) -- (pic cs:bar); 
\end{tikzpicture}
\end{document}

这也带来了：

! Missing number, treated as zero.
<to be read again> 
                   i
l.10    \draw (pic cs:foo)
                           -- (pic cs:bar);

所以它独立于chappg。
