Misbehaviour when subfiles is used with standalone

[markellos918]

Inputting a tex file in a subfile when the standalone package is loaded causes the appearance in the pdf (of both the subfile and the master file) of a text string containing excerpts of the path. This is related to the presence of spaces in the folders names.

Files are organised as follows:

master.tex
        sub folder_space/input.tex
        subfolder_nospace/input.tex
        subfiles/space.tex
        subfiles/nospace.tex

master.tex:

\documentclass{book}
\usepackage{subfiles}
\usepackage{standalone}
\usepackage{lipsum,}

\begin{document}

\subsection*{The input file is in a directory containing a space in the name but is not called form within a subfile}
\input{"sub folder_space"/input}
\subfile{subfiles/space}
\subfile{subfiles/nospace}

\end{document}

Both input files:
\lipsum[1]

subfiles/space.tex:

\documentclass[../master]{subfiles}
\begin{document}

\subsection*{The input file is in a directory containing a space in the name}
\input{../"sub folder_space"/input}
\end{document}

\end{document}

subfiles/nospace.tex

\documentclass[../master]{subfiles}
\begin{document}

\subsection*{The input file is in a directory NOT containing a space in the name}
\input{../"subfolder_nospace"/input}
\end{document}

\end{document}

In the pdf this is the string that shows up: folder ̇space/input.texfolder ̇space/input.tex. Please notice the high dots.
The issue only occurs with subfiles >1.6 (in my test 2.2).

Thanks for the report. I will investigate the issue.

I have narrowed down the issue to an incompatibility between the package import.sty (used by subfiles) and the standalone package. I have reported the issue to the bug tracker of standalone.

Thanks for reporting the issue. What I think is strange is that the bug only showed up with packages updates that were released in the last six months (after July 2020 let’s say). Neither import.sty nor standalone were updated in that time frame.

[gsalzer]

standalone loads several other packages, and some of them changed recently, like filehook.sty 2020/09/29 v0.8a (which might be the key to the problem). Also the LaTeX format changed: LaTeX2e <2020-10-01> patch level 3 (which is the reason why all the packages, including subfiles, had to update).

Downgrading filehook to v0.7a does indeed fix the issue.
