ConTeXt：在标题文本下画一条线

有时，为了将标题文本与文本区域分开，我需要在标题文本下方画一条线。

\setuppagenumbering
[location=,
 alternative=doublesided]

\definepagebreak
[chapterpagebreak]
[yes,header,footer,right]

\setuphead
[chapter]
[style=\bfc,
 header={empty,nomarking}, 
 page=chapterpagebreak]

\def\pageoddoreven{%
\ifodd\pagenumber
  {\getmarking[sectionnumber]\hskip1em\getmarking[section][first]}
\else
  {Chapter~\getmarking[chapternumber]\hskip1em\getmarking[chapter]}
\fi}

\setupheadertexts
[text][\pageoddoreven][pagenumber]

\setupheader
[style=bold,after=\thinrule]

\starttext
\chapter{First Chapter}
this is the first chapter
\page   
the second page of the first chapter
\chapter{Second Chapter}
this is the second chapter
\page
the second page of the second chapter
\stoptext

但\thinrule将跨越整个页面，这就是我想要的。

细规则

我想要一条仅横跨文本区域的线，不延伸到左右边缘。我该如何绘制这条线？

正如 Timothy Li 所说，Aditya 的解决方案在每一页上都画了线。可以定义一个只出现在有内容的页面上的页眉（或页脚）。就我的目的而言，我使用了页脚，但以下代码同样可以应用于页眉：

\setuphead[chapter][
  header=empty,
]

% Define the appearance for the section name in the footer.
\defineframed[FooterSection][
  frame=off,
  topframe=on,
  align=flushleft,
  width=\makeupwidth,
  rulethickness=1.6pt,
  location=bottom,
  foregroundstyle=\tfx\ss,
  height=broad,
  top={\blank[small]},
]

% Define the appearance of the page number in the footer.
\defineframed[FooterPage][
  frame=off,
  location=bottom,
  foregroundstyle=\tfx\bold\ss,
]

% Include the section name and page number in the footer.
\setupfootertexts
  [\FooterSection{\getmarking[section]}]
  [\FooterPage{\pagenumber}]

\starttext
  \startfrontmatter

  \startstandardmakeup
    \startalignment[middle]\tfa{Title Page}\stopalignment
  \stopstandardmakeup

  \setuppagenumbering[conversion=romannumerals]
  \setcounter[userpage][1]
  \completecontent
  \stopfrontmatter

  \startchapter [title=alpha] \stopchapter
    \startsection[title=alphasec] \stopsection
  \startchapter [title=beta]  \stopchapter
    \startsection[title=alphasec] \stopsection
  \startchapter [title=gamma] \stopchapter
    \startsection[title=alphasec] \stopsection
\stoptext

这是实现此目的的一种方法。另请注意，我清理了您设置标题文本的方式。

\setuplayout
  [
    header=\lineheight,
    headerdistance=\lineheight,
  ]

\setuppagenumbering
  [
    location=,
    alternative=doublesided,
  ]

\definepagebreak
  [chapterpagebreak]
  [yes,header,footer,right]

\setuphead
  [chapter]
  [
    style=\bfc,
    header=empty,
    page=chapterpagebreak,
  ]

\setupheader[style=bold]

\setupheadertexts
  [{\getmarking[sectionnumber]\hskip1em\getmarking[section][first]}]
  [pagenumber]
  [{Chapter~\getmarking[chapternumber]\hskip1em\getmarking[chapter]}]
  [pagenumber]

\setupbackgrounds[header][text][bottomframe=on]

\starttext
\chapter{First Chapter}
this is the first chapter
\page   
the second page of the first chapter
\chapter{Second Chapter}
this is the second chapter
\page
the second page of the second chapter
\stoptext

编辑要删除空白页上的页眉，请使用：

\unprotect
\installpagebreakmethod {reallyempty}
  {\page_otr_flush_all_floats
   \page_otr_command_next_page
   \doifnot{\namedlayoutelementparameter\v!header\c!state}\v!stop{\setuplayoutelement[\v!header][\c!state=\v!high]}%
   \doifnot{\namedlayoutelementparameter\v!footer\c!state}\v!stop{\setuplayoutelement[\v!footer][\c!state=\v!high]}%
   \page_otr_insert_dummy_page}
\protect

\definepagebreak
  [chapterpagebreak]
  [yes,reallyempty,right]

\setuphead
  [chapter]
  [
    style=\bfc,
    header=high,
    before={\blank[force,\the\headerheight]},
    page=chapterpagebreak,
  ]
