Question

Si tengo un documento cuyo nombre es my exam.tex, ¿es posible hacer que su archivo PDF de salida tenga el nombre de my exam [solved].pdfagregando la palabra[solved] solocuando la answersopción de clase está habilitada?

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

Answer 1

Aquí está mi solución a este problema.

Si compila sin -shell-escape, simplemente se ejecuta normalmente (es decir, si está usando la answersopción, generará respuestas; de lo contrario, no; \jobnamese usa el valor predeterminado).

Si compila con -shell-escape, genera dos archivos: \jobname.pdfcon preguntas y \jobname-solved.pdfcon respuestas. Lo hace independientemente de si la answersopción se pasa a la clase o no.

Lo he usado latexmkpara que las múltiples compilaciones requeridas se tengan en cuenta automáticamente.

Si solo desea generar un archivo a la vez, puede modificar ligeramente la respuesta anterior para que latexmksolo se llame cuando la answersopción realmente se pase a la examclase. Esto responde a su pregunta tal como la ha formulado. Todavía es necesario compilarlo con -shell-escape.

\documentclass[answers]{exam}

\usepackage{pdftexcmds}
\usepackage{iftex}

\makeatletter

\ltx@IfUndefined{pdf@shellescape}
  {}
  {\ifnum\pdf@shellescape=1
     \ifpdftex
       \def\latexmkengine{-pdf}%
     \fi
     \ifluatex
       \def\latexmkengine{-lualatex}%
     \fi
     \ifxetex
       \def\latexmkengine{-xelatex}%
     \fi
     \ifprintanswers
       \pdf@system{%
         latexmk \latexmkengine\space -jobname="\jobname-solved" "\jobname"
       }%
       \expandafter\expandafter\expandafter\stop
     \fi
   \fi}

Y una expl3solución que maneja nombres de archivos con espacios. Todavía es necesario, -shell-escapepor supuesto.
