如果我有一個名為 的文檔，是否可以透過附加單字來my exam.tex使其輸出 PDF 文件的名稱為my exam [solved].pdf[solved] 僅有的何時啟answers用班級選項？

\documentclass[answers]{exam}
\begin{document}
    text
\end{document}

答案1

這是我對這個問題的解決方案。

如果您在沒有 的情況下編譯-shell-escape，它只會正常運行（即，如果您使用該answers選項，它將輸出答案，否則不會；\jobname使用預設值。）

如果使用 進行編譯-shell-escape，則會輸出兩個檔案：\jobname.pdf包含問題和\jobname-solved.pdf答案。無論answers選項是否傳遞給類​​別，它都會執行此操作。

我已經使用了latexmk自動考慮所需的多次編譯。

\usepackage{iftex}

\makeatletter

\ltx@IfUndefined{pdf@shellescape}
  {}
  {\ifnum\pdf@shellescape=1
     \ifpdftex
       \def\latexmkengine{-pdf}%

         -usepretex="\string\AtBeginDocument{\string\printanswerstrue}"
         "\jobname"
     }%
     \pdf@system{%
       latexmk \latexmkengine\space
         -usepretex="\string\AtBeginDocument{\string\printanswersfalse}"
         "\jobname"
     }%
     \expandafter\stop
   \fi}

\makeatother

\begin{document}
\begin{questions}
  \question One of these things is not like the others; one of these things is
  not the same. Which one is different?
  \begin{oneparchoices}
    \choice John
    \choice Paul
    \choice George
    \choice Ringo
    \CorrectChoice Socrates
  \end{oneparchoices}
\end{questions}
\end{document}

輸出

\jobname.pdf

輸出

\jobname-solved.pdf

輸出

如果您只想一次輸出一個文件，您可以稍微修改上面的答案，以便僅在選項實際傳遞給類別latexmk時調用。正如您所問的那樣，這回答了您的問題。它仍然需要用 來編譯。answersexam-shell-escape

以及expl3處理帶有空格的檔案名稱的解決方案。當然還是需要的-shell-escape。
