如何调整 ConTeXt 目录中条目的位置？

我有一个定义如下的目录：

\setuphead[part][number=no]
\setuphead[chapter][number=no]
\setuphead[section][number=no]

\setuplist[part][alternative=a, margin=0em]
\setuplist[chapter][alternative=a, margin=0em]
\setuplist[section][alternative=d, margin=0em]

\starttext
    \startfrontmatter
        \completecontent
    \stopfrontmatter
    \startbodymatter
        \part{This is a part title}
            \chapter{This is a chapter title}
                \section{This is a section title}
                \section{This is another section title}
    \stopbodymatter
\stoptext

编译后显示如下：

Contents

   This is a part title 2

    This is a chapter title 3
This is a section title   3 This is another section title   3

这有三个问题：

  • 各个部分级别没有水平对齐。
  • alternative=a和的章节标题条目和页码之间的水平距离不同alternative=d。
  • 垂直行距不一致。

我想创建这样的结果：

Contents

This is a part title   2
This is a chapter title   3
This is a section title   3 This is another section title   3
  • 为什么alternative=a和alternative=d看起来如此不同？
  • 我怎样才能使条目沿左侧排列、一致地设置页码的位置以及调整行距以使所有条目都相同？

答案1

我怎样才能使条目沿左侧排列、一致地设置页码的位置以及调整行距以使所有条目都相同？

distance可以通过设置列表的和参数来控制左对齐，通过下一个较低类别（尝试）的和键来控制width行距。beforeafterblank[line]

但是，章节列表中页码的间距在 listalternative 中是固定的。要解决这个问题，您可以定义自己的替代命令。

\setuphead    [part] [number=no]
\setuphead [chapter] [number=no]
\setuphead [section] [number=no]

%% Set the spacing left of the page number.
\newdimen \mypagenumdistance \mypagenumdistance .7em
\def\fillercmd{\nobreak\hskip\mypagenumdistance}
%% Install the spacing handler for use with alternative “a” in the part
%% and chapter list.
\setuplistalternative [a] [width=\zeropoint,filler=\fillercmd,]
%% Define a list alternative for the section list; we drop the structure
%% number (arg #1) as in the question.
\definelistplacement[my_list_placement][command]#1#2#3%
  {#2\fillercmd#3\hskip1.5em}
%% Part and chapter lists need their distance and width dimensions
%% nil’ed.
\setuplist    [part] [alternative=a, distance=\zeropoint, width=\zeropoint,before=,]
\setuplist [chapter] [alternative=a, distance=\zeropoint, width=\zeropoint,before=,]
%% Hook our list placement into the section list.
\setuplist [section] [alternative=my_list_placement]
%% Section list hook.
\startsetups toc:section
    \noindentation\placelist[section]
\stopsetups
%% Chapter list hook, with transition to the section list.
\startsetups toc:chapter
    \noindentation\placelist[chapter][after=\setups{toc:section}]
\stopsetups

\starttext
    \startfrontmatter
        %% \completecontent is imprecise, we’ll do it ourselves.
        \title{Contents}
        %% Part list is the top level structure, contains the chapter hook.
        \placelist [part] [criterium=text,after=\setups{toc:chapter}]
    \stopfrontmatter
    %% Testing section.
    \startbodymatter
      \dorecurse{3}{%
        \part{This is a part title}
          \dorecurse{5}{%
            \chapter{This is a chapter title}
                \dorecurse{10}{\section{some section title}}%
          }
      }
    \stopbodymatter
\stoptext

使用最新版本的 mkiv 会产生以下输出：示例目录
