I have a document with a very long preamble in the separate file general.tex. The main.tex looks something like

\documentclass[10pt, letterpaper]{article}

\input{general.tex}

\usepackage{subfiles}

\begin{document}

\end{document}

In general I set my main files as Arial with ttf files that looks something like

\setsansfont[
BoldFont=ARIAL/arialbd.ttf,
ItalicFont=ARIAL/ariali.ttf,
BoldItalicFont=ARIAL/arialbi.ttf
]{ARIAL/arial.ttf}

and when compiling main.tex it appears as it should but when trying to compile subfiles the formatting from the preamble is gone. I'm not sure if it is every setting in general.tex and am working on checking but the most obvious is the lack of Arial. What am I doing wrong and how do I fix this? Thanks so much!

  • Welcome to TeX.SX! Can you please provide a complete example, main file and subfile, that we can typeset and that illustrates your problem? In general, putting the preamble into a separate file works. At the moment, you do not provide enough information to give a meaningful answer.

    If my answer solves your problem, your question is a prime example for why it is important to provide a complete document illustrating the issue, and not just the information one deems relevant. From your original question, it is impossible to guess the source of the problem.

1 Answer 1

I was able to typeset your document on Linux (TeXlive) and Windows (MikTeX) after the following changes, with both main and subfile using the same Arial-like sans serif font.

  1. Move the command

    \setmainfont{Arial}
    

    to a place where it will be executed when typesetting the main file and the subfile. At the moment, it is only executed for the main file, but ignored for the subfiles. Move it e.g. immediately before \begin{document}, or into general.tex.

  2. In general.tex, comment out the line

    \usepackage{XCharter} % Use the XCharter font
    

    On both systems, Linux and Windows, I get an error message about a conflict with the fontspec package. Probably this package is not needed anyway, given that you are intending to use a sans-serif font, while XCharter has serifs.

  3. On both of my systems, there are no fonts ARIAL/arial*.ttf installed, so in general.tex, I commented out the lines

    \setsansfont[
    BoldFont=ARIAL/arialbd.ttf,
    ItalicFont=ARIAL/ariali.ttf,
    BoldItalicFont=ARIAL/arialbi.ttf
    ]{ARIAL/arial.ttf}
    

I suggest to perform the same changes, to verify that both main and subfile come out in the same Arial-like font, and then reintroduce font commands if needed (while checking the log for errors).

Debugging: As the subfiles package adds an extra layer of complexity, it may help, in case of errors, to ensure first that the subfile typesets correctly without subfiles. In a copy of the subfile (at the same location),

  1. replace the line \documentclass...{subfiles} by the preamble of the main file, including its \documentclass command.

  2. make sure that the paths are corrected; e.g., in your sample document replace \input{general.tex} by \input{../general.tex}.

If the problem also occurs with this copy (here: does not typeset in the correct font), then the issue is not related to using subfiles, but lies somewhere else. If, on the other hand, the modified copy runs without problems, then there is probably an issue with some file path. See section 3.2 of the documentation on hints how to fix it.

Last word: consider not using the subfiles package. In many cases, it works just as well by having a list of \input statements in the main file and then commenting out those that should not be typeset.

  • This change made it so none of the files loaded in Arial.

  • My first answer actually was a bit brief, concentrating on what I thought was essential. Hope you get a step further now.
