Overleaf - Compiling multiple .tex files into multiple outputs (alternatively, nesting document classes?)

Question

Clarification: I am looking for a way to automatically run pdflatex on multiple .tex files to produce multiple separate .pdf files when I click the Recompile button in Overleaf.

I have multiple .tex files, which have different document classes in Overleaf. Because they have different document classes, I don't believe that the subfiles package is a viable solution.

I have currently been compiling them separately and uploading the result back into Overleaf, but this solution is not the best if you forget to compile one file that you updated.

I believe that maybe latexmk can be used for this.

An alternative solution to this, and possibly a better solution: is there a way of nesting different document classes? If so, I can just use \input on the subfiles.

Thank you in advance!

Answer 1

There are several ways of handling multiple documents

for example if you have an article class doc1 and a memoir doc2

You can have a main.tex

\documentclass{article}

\usepackage{pdfpages}
\usepackage{shellesc}

\ShellEscape{pdflatex doc1}
\ShellEscape{pdflatex doc2}

\begin{document}

\includepdf[pages=-]{doc1.pdf}
\includepdf[pages=-]{doc2.pdf}

\end{document}

That includes

doc1

\documentclass{article}

\begin{document}

an article
\end{document}

and

doc2

\documentclass{memoir}

\begin{document}

a memoir
\end{document}

If you hit recompile on the main document it will run pdflatex on all three.
