위의 코드는 파일을 만듭니다 Theorem.tex
. 하지만 모든 댓글(이것은 댓글 1, 이것은 댓글 2)이 사라집니다. 모든 댓글을 보관하는 방법은 무엇입니까 %this is comment 1, %this is comment 2
?
답변1
\documentclass[12pt,a4paper,oneside]{book}
\begin{document}
\newwrite\copyfile
\immediate\openout\copyfile=Theorem.tex
{\catcode`\%=12
\immediate\write\copyfile{hello %this is comment 1
%this is comment 2
}
}
\immediate\closeout\copyfile
\end{document}
catcode 12를 사용하면 %
주석 상태가 사라집니다. (개행 문자를 보존하고 싶을 수도 있습니다.)
위의 내용은
hello %this is comment 1 %this is comment 2
\documentclass[12pt,a4paper,oneside]{book}
\begin{document}
\newwrite\copyfile
\immediate\openout\copyfile=Theorem.tex
{\catcode`\%=12
\endlinechar=`\^^J%
\immediate\write\copyfile{hello %this is comment 1
%this is comment 2
}%
}%
\immediate\closeout\copyfile
\end{document}
생산하다
hello %this is comment 1
%this is comment 2

모든 특수 문자를 허용하는 더 복잡한 예입니다. 이는 Plain LuaTeX 및 LuaLaTeX에서 작동하며 일부 변경 사항을 적용하면 다른 엔진에서도 작동합니다. 구현은 filecontents
LaTeX 커널 환경 과 유사합니다 .
\catcode`@=11
\newwrite\file
\immediate\openout\file=xxx.zzz\relax
\newif\if@firstline
\def\@makeother#1{\catcode`#112\relax}

Let's test:
\verbatimwrite\file\endverbatimwrite This is deleted!
