计算 latex 中特定单词出现的次数

Question

我已经定义了\GreenCircle，\AmberCircle并\RedCircle根据段落的内容在段落开始前显示绿色、琥珀色或红色圆圈。在运行 latex 时，是否可以计算文档末尾每个圆圈的数量？例如：

Number of Green Circles:
Number of Amber Circles:
Number of Red Circles:  

Answer 1

好吧，为每种圆圈类型定义一个计数器并\stepcounter{redcircle}在\RedCircle命令中使用等，最后使用\theredcircle

\documentclass{article}

\newcounter{redcircle}
\newcounter{greencircle}
\newcounter{ambercircle}


\newcommand{\RedCircle}{%
  \stepcounter{redcircle}%
  % Rest of the redcircle command
}

\newcommand{\GreenCircle}{%
  \stepcounter{greencircle}%
  % Rest of the greencircle command
}

\newcommand{\AmberCircle}{%
  \stepcounter{ambercircle}%
  % Rest of the amberircle command
}



\usepackage{blindtext}

\begin{document}

\RedCircle
\blindtext[10]

\RedCircle
\blindtext[10]



\GreenCircle
\blindtext

\AmberCircle
\blindtext
\GreenCircle
\blindtext


\clearpage
Number of Green Circles: \thegreencircle

Number of Red Circles: \theredcircle

Number of Amber Circles: \theambercircle

\end{document}
