마지막 환경을 기반으로 한 카운터 값

Question

규칙이 마지막 환경만 활성화해야 하는 TeX 매크로를 사용하여 조건을 설정하는 방법은 무엇입니까 test?

문서에 규칙이 하나만 포함되어 있다고 가정해 보겠습니다 \begin{test}...\end{test} .

\begin{test}...\end{test}문서 규칙에 여러 개가 포함된 경우 마지막에만 활성화해야 합니다 \begin{test}...\end{test}.

\documentclass{book}
\pagestyle{empty}
\makeatletter
\newif\ifruletest\global\ruletestfalse
\newcounter{testcounter}
\setcounter{testcounter}{0}

\newenvironment{test}{\noindent\parindent0pt}
{\par\stepcounter{testcounter}
\ifnum\value{testcounter}>0\rule{\textwidth}{1bp}\global\ruletestfalse\else\fi\bigskip}


\makeatother

Answer 1

당신이 사용할 수있는 totcount; 환경 수가 test변경되면 LaTeX를 두 번 실행해야 합니다.

\documentclass{book}
\usepackage{totcount}

\newtotcounter{testcounter}

\newenvironment{test}
 {\par\setlength{\parindent}{0pt}}
 {\par\stepcounter{testcounter}
  \ifnum\totvalue{testcounter}=\value{testcounter}%
    \nobreak\rule{\textwidth}{1bp}\bigskip
  \fi}

\begin{document}

\begin{test}
Sample text Sample text Sample text Sample text
