KOMA-Script 图层中的索引

KOMA-Script 图层中的索引

背景。 我想更换故意留白的页面或者空页 在scrbook每张空白页上都会显示一条新引文。感谢scrbook而 LuaTeX 编写起来并不难。

这是我的问题。 不幸的是，这些页面的索引不起作用。条目未显示在.idx文件中。

评论。

  • 选择与 LuaTeX 不同的引擎不是一个选择。
  • tables这里没有显示从 Lua 访问引用的代码，以避免 MWE 臃肿和.lua文件分离。
  • 选择不同的类别scrbook不是一个选择。
  • 页眉和页脚也出现相同的问题。
  • 索引index does work here A和index does work here B工作正常。

我的 MWE。

\documentclass[paper=a4,twoside]{scrbook}

\usepackage{fontspec,polyglossia}
\setdefaultlanguage[variant=usmax]{english}

\usepackage{hyperref,makeidx}

\usepackage{scrlayer,scrlayer-scrpage}
\DeclareNewLayer[
foreground,
align=l,
area={.25\paperwidth}{.37\paperheight}{.5\paperwidth}{.5\paperheight},
contents={A quote which is accessed by Lua. But not in the MWE. But the \textbf{index}\index{index does not work here} does not work here!
Just some Lua code: \directlua{tex.sprint(math.exp(-1))}.}
]{intentionallyBlankLayer}
\DeclareNewPageStyleByLayers{intentionallyBlank}{intentionallyBlankLayer}
\KOMAoptions{cleardoublepage=intentionallyBlank}

\ihead[bar \index{bar head index does not work}]{foo \index{foo head index does not work}}
\ifoot[bar \index{bar foot index does not work}]{foo \index{foo foot index does not work}}

\makeindex
\begin{document}

\chapter{Lorem foo}
Some text with a working index\index{index does work here A}.
\chapter{Lorem bar}
Some other text with a working index\index{index does work here B}.

\printindex
\end{document}

答案1

页面样式在输出例程中使用，并且\index被重新定义为不执行任何操作。您可以尝试使用低级命令编写索引条目，但这样您就无法从 hyperref 获得链接。您还可以将索引代码移动到onselect页面样式的 -hook。但由于可以在各个地方选择页面样式，而无需在最后使用，因此您可能会得到太多的索引条目。onevenpage-option 看起来更合乎逻辑，但不起作用。

答案2

乌尔丽克·菲舍尔在她的评论中描述了不同的解决方案KOMA-Script 图层中的索引重新定义\cleardoublepage。我希望有一个优雅的解决方案，不基于覆盖某些东西。以下代码基于https://tex.stackexchange.com/a/205536/128553。

\documentclass[paper=a4,twoside]{scrbook}

\usepackage{fontspec,polyglossia}
\setdefaultlanguage[variant=usmax]{english}

\usepackage{hyperref,makeidx}

\usepackage{scrlayer,scrlayer-scrpage}
\newcommand*{\blankpage}{%
  \par\vspace*{\fill}%
  {A quote which is accessed by Lua. But not in the MWE. But the \textbf{index}\index{index does now work here} does not work here!
Just some Lua code: \directlua{tex.sprint(math.exp(-1))}.}
  \vspace{\fill}%
}
\makeatletter
\renewcommand*{\cleardoubleoddstandardpage}{%
  \clearpage
  \if@twoside
    \ifodd\c@page
    \else
      \blankpage
      \thispagestyle{empty}%
      \newpage
      \if@twocolumn\hbox{}\newpage\fi
    \fi
  \fi
}
\makeatother

\makeindex
\begin{document}

\chapter{Lorem foo}
Some text with a working index\index{index does work here A}.
\chapter{Lorem bar}
Some other text with a working index\index{index does work here B}.

\printindex
\end{document}

评论。这个答案是问题的一部分，现在作为答案发布以遵守本网站的惯例。答案https://tex.stackexchange.com/a/360327/128553因给出两个解决方案而被接受，而这个解决方案只是她第二个建议的实现。
