行号在“lineno”包内

我对这个 MWE 有疑问

\documentclass{article}
\usepackage{lineno}

\parindent=0pt
\renewcommand{\thelinenumber}{-\arabic{linenumber}-}

\begin{document}
\linenumbers
Text \thelinenumber\ text \\
Text \thelinenumber\ text \\
Text \thelinenumber\ text \par
Text \thelinenumber\ text 

\end{document}

在此处输入图片描述

除 之后的行外，其他行内的计数器linenumber均未增加\par，与页面左侧显示的行号相反。

如何在行内显示或使用行号（例如在条件中）？

答案1

为了提取序数行号的表示，你可以设置一个\linelabel，并使用常规的组合来检索它\getrefnumber（从refcount；避免将其提取到计数器）和\ordinalnum（从fmtcount）。

在此处输入图片描述

\documentclass{article}

\usepackage{lineno,refcount,fmtcount,xcolor}

\setlength{\parindent}{0pt}
\renewcommand{\thelinenumber}{-\arabic{linenumber}-}
\renewcommand{\theLineNumber}{\arabic{linenumber}}

\newcounter{linecntr}
\newcommand{\ordinalline}{%
  \stepcounter{linecntr}%
  \begingroup\edef\x{\endgroup\noexpand\linelabel{linecntr-\thelinecntr}}\x%
  \textcolor{red}{\ordinalstringnum{\getrefnumber{linecntr-\thelinecntr}}}}

\begin{document}
\linenumbers
