使用点填充使文本居中

Question

我正在写一份合同，当行结束时，以及当文本居中时，使用点来填充空白处。所以我在寻找一个居中的文本，左右两侧都有点。类似于： \dotfill text \dotfill。我找到了一种方法，但也许还有更有效的方法：

\begin{center}
    \begin{minipage}[b]{0.37 \textwidth}
        \dotfill
    \end{minipage}% 
    \begin{minipage}[b]{0.25\textwidth}
        \centering
        TEXTSAMPLE
    \end{minipage}
    \begin{minipage}[b]{0.37\textwidth}
        \dotfill
    \end{minipage}
\end{center}

Answer 1

使用最新的 LaTeX 版本，您可以执行以下操作：

\documentclass{article}

\ExplSyntaxOn

\NewDocumentEnvironment{fillcenter}{+b}
 {
  \begin{center}
  \seq_set_split:Nnn \l_tmpa_seq { \\ } { #1 }
  \dotfill \seq_use:Nn \l_tmpa_seq { \\ \dotfill }
  \end{center}
 }
 {}

\ExplSyntaxOff

\AddToHook{para/end}[dotfill]{\ifhmode\unskip\dotfill\fi}

\begin{document}

This is a paragraph where the final blank space is
filled with dots.
This is a paragraph where the final blank space is
filled with dots.

\begin{fillcenter}
This is a centered \\
block where the \\
filling is on \\
either side
\end{fillcenter}

And this is again filled.

\end{document}

Answer 2

快速实验：

\documentclass{article}
\usepackage[showframe]{geometry}
\begin{document}
\begin{center}
\dotfill TEXTSAMPLE\dotfill
\end{center}

\begin{center}
\dotfill\ TEXTSAMPLE\ \dotfill
\end{center}

\begin{center}
    \begin{minipage}[b]{0.37\textwidth}
        \dotfill
    \end{minipage}%
    \begin{minipage}[b]{0.25\textwidth}
        \centering
        TEXTSAMPLE
    \end{minipage}%
    \begin{minipage}[b]{0.37\textwidth}
        \dotfill
    \end{minipage}
\end{center}
\end{document}
