经典论文草稿标尺上的重复数字

Question

当使用选项draft来classicthesis处理文档时，会显示顶部和底部标尺。但是，几乎在每种情况下，它们的数字都是重复的（有时在从模式切换到final模式后第一次编译时不会出现deaft这种情况）。可以以某种方式修复此行为吗？

\documentclass[draft]{scrbook}

\usepackage{blindtext}

\ifdim\overfullrule>0pt
  \PassOptionsToPackage{draft=false}{scrlayer-scrpage}
  \usepackage{xcolor}
  \AfterPackage*{scrlayer-scrpage}{%
%    \DeclareNewLayer[
%      head,
%      height=0pt,
%      foreground,
%      contents=\textcolor{gray!70}{\layercontentsmeasure}
%    ]{head.ruler}
    \DeclareNewLayer[
      foot,
      height=\textheight+0.1cm,
      addvoffset=-\textheight-1.2cm,
      background,
      contents=\textcolor{lightgray}{\layercontentsmeasure}
    ]{foot.ruler}
    \AddLayersAtBeginOfPageStyle{scrheadings}{foot.ruler}
    \AddLayersAtBeginOfPageStyle{plain.scrheadings}{foot.ruler}
    \AtBeginDocument{\chead*{DRAFT}\cfoot*{DRAFT}}
  }
\fi

\usepackage{classicthesis}
\usepackage{arsclassica}
\usepackage[margin=3cm,heightrounded]{geometry} % just to show bigger rulers
\usepackage{lipsum}% only for dummy text

\begin{document}

\chapter{Chapter one}

编辑#2：下面问题中唯一未解决的问题现在似乎是将数字及其引导线放在 bix 之外，以便可以将其缩小到与 完全相同的大小textarea。

编辑：现在我几乎设法获得了所需的结果，但我的修改方式非常不专业。我认为需要进行以下更改才能获得最终的改进：

1. 显示标尺也是垂直方向的，大致围绕文本块（类似于showframe），一边以厘米为单位，另一边以英寸为单位（解决了）；
2. 将数字及其线条放在标尺矩形的外面（这样它们就不会干扰文本或头部/脚部）（未解）；
3. 在章节（目录等）页面中添加单词“DRAFT”（解决了）；
4. 将“DRAFT”一词垂直移动到离页面边框更近的地方，这样它就不会干扰文档本身的页眉/页脚（解决了）。

以下是我得到的（部分）结果。

\documentclass[draft]{scrbook}

\usepackage{soulutf8}

\usepackage{ifdraft}

\ifoptiondraft{%
    \PassOptionsToPackage{draft=false}{scrlayer-scrpage}
    \PassOptionsToPackage{draft=false}{microtype}
    \usepackage{xcolor}
    \AfterPackage*{scrlayer-scrpage}{%
        \def\myrcoeff{1}
        \DeclareNewLayer[
        textarea,
        addvoffset=\myrcoeff\dimexpr-\headsep\relax,
        height=\textheight+\myrcoeff\dimexpr\headsep+\footskip-\footheight\relax,

        width=\textwidth+\myrcoeff\dimexpr+2\headsep+\footskip-\footheight\relax,

        ]{textarea.ruler}
        \AddLayersAtBeginOfPageStyle{scrheadings}{textarea.ruler}
        \AddLayersAtBeginOfPageStyle{plain.scrheadings}{textarea.ruler}

Answer 1

选项draft为图层页面样式的每一层添加标尺。由 定义的页面样式scrlayer-scrpage由 10 个图层组成，每页使用其中 6 个图层：请参阅使用 scrlayer-scrpage 的“草稿”类/包选项。

draft即使设置了类选项，为了避免标尺，也传递draft=false给包选项scrlayer-scrpage：

\documentclass[draft]{scrbook}
\PassOptionsToPackage{draft=false}{scrlayer-scrpage}
\usepackage{classicthesis}

\usepackage[margin=3cm]{geometry} % just to show bigger rulers
\usepackage{lipsum}% only for dummy text
\begin{document}
\lipsum[1]
\parbox[t]{\textwidth}{\lipsum[2]}% to see the overfullrule if draft is enabled
\end{document}

你可以用 content 定义自己的图层\layercontentsmeasure。下面是显示页眉和页脚基线的位置和长度的示例：

\documentclass[draft]{scrbook}
\ifdim\overfullrule>0pt
  \PassOptionsToPackage{draft=false}{scrlayer-scrpage}
  \usepackage{xcolor}
  \AfterPackage*{scrlayer-scrpage}{%
    \DeclareNewLayer[
      head,
      height=0pt,
      foreground,
      contents=\textcolor{gray!70}{\layercontentsmeasure}
    ]{head.ruler}
    \DeclareNewLayer[
      foot,
      height=0pt,
      addvoffset=\footheight-\dp\strutbox,
      background,
      contents=\textcolor{lightgray}{\layercontentsmeasure}
    ]{foot.ruler}
    \AddLayersAtBeginOfPageStyle{scrheadings}{head.ruler,foot.ruler}
    \AddLayersAtBeginOfPageStyle{plain.scrheadings}{head.ruler,foot.ruler}
    \AtBeginDocument{\chead*{DRAFT}\cfoot*{DRAFT}}
  }
\fi
\usepackage{classicthesis}
\usepackage{arsclassica}
\usepackage[margin=3cm]{geometry} % just to show bigger rulers
\usepackage{lipsum}% only for dummy text
\begin{document}
\lipsum[1]
\end{document}

Answer 2

这是我第一次尝试得到的结果：

\documentclass[draft]{scrbook}

\usepackage{ifdraft}

\ifoptiondraft{%
    \PassOptionsToPackage{draft=false}{scrlayer-scrpage}
    \usepackage{scrlayer-scrpage}
    \usepackage{xcolor}
    \newcommand*\showlayer[2][black]{%
        \IfLayerAtPageStyle{scrheadings}{#2}{%
            \DeclareNewLayer[clone=#2,contents=\textcolor{#1}{\layercontentsmeasure}]{#2.size}%
            \AddLayersToPageStyleAfterLayer{scrheadings}{#2.size}{#2}%
        }{}%
    }
    %\showlayer[lightgray]{scrheadings.head.oneside}
    \showlayer[red!30]{scrheadings.head.below.line}
    %\showlayer[green!30]{scrheadings.head.above.line}
    %\showlayer[lightgray]{scrheadings.foot.oneside}
    \showlayer[red!30]{scrheadings.foot.above.line}%
    %\showlayer[green!30]{scrheadings.foot.below line}%
}{}

\usepackage{classicthesis}
\usepackage{arsclassica}

\ifoptiondraft{%
    \chead{DRAFT}
    \cfoot{DRAFT}%
}{}

\usepackage[margin=3cm]{geometry} % just to show bigger rulers

\begin{document}
    Text.
