I have a document made up of many sub-documents. These documents can be compiled separately using LaTeX and the subfiles package but not when I use both newtxtext and bm as well. How can I overcome this?

For example, file main.tex:

\documentclass{report}
\usepackage{newtxtext}
\usepackage{newtxmath}
\usepackage{bm}
\usepackage{subfiles}
\begin{document}
\subfile{sub1}
\end{document}

File sub1.tex in the same directory:

\documentclass[main]{subfiles}
\begin{document}
$\bm{x}$
\end{document}

The main file compiles without a problem, but trying to compile sub1 by itself reports an error but only when newtxtext is included.

The log file tells me

Runaway argument?
{document}\ifx \reserved@a \@currenvir \else \@badend {document}\fi  \clearpage 
\ETC.
! File ended while scanning use of \reserved@a.
<inserted text> 
                \par 
<*> \input sub1.tex

I suspect you have forgotten a `}', causing me
to read past where you wanted me to stop.
I'll try to recover; but if the error is serious,
you'd better type `E' or `X' now and fix your file.

! Emergency stop.
<*> \input sub1.tex

*** (job aborted, no legal \end found)

Adding a paragraph break between $\bm{x}$ and the \end{document} gives the message

! Paragraph ended before \bm@test@token was complete.

Searching for this message brings up the question Package incompatibilites: etoolbox, hyperref, and bm, standalone?. Could this be a similar problem?

Adding \listfiles gives

Inspired by the question Package incompatibilites: etoolbox, hyperref, and bm, standalone?, in etoolbox.sty I commented out

\patchcmd\enddocument
  {\deadcycles}
  {\let\AfterEndDocument\@firstofone
   \@afterenddocumenthook
   \deadcycles}
  {}
  {\let\etb@@end\@@end
   \def\@@end{%
     \let\AfterEndDocument\@firstofone
     \@afterenddocumenthook
     \etb@@end}}
{<environment>}{<code>}

This allows sub1.tex to be compiled on its own without error. This suggests that there is a conflict of the type described in the linked question.

    Sorry, but I get no error. – egreg May 27 '14 at 18:06

    I get no error with a blank line after $\bm{x}$ either. – egreg May 27 '14 at 20:29
  • Thank you for attempting to reproduce the problem. Could you share you log file so that I can compare it with mine? The fact that you can't reproduce it suggests there is a problem with my installation of the packages but the fact that the main file compiles as expected suggests otherwise. – Quarticle May 28 '14 at 08:44
  • Please, add \listfiles to your main document and report the relevant part of the .log file you get. – egreg May 28 '14 at 09:42
  • You have an old TeX distribution (report.cls has been last changed on 2007/10/19 and amsmath.sty on 2013/01/14, for instance). Adding the most recent version of newtx and subfiles to such an old distribution can expose to all kinds of problems. Update your TeX distribution, which seems to be eight years old. – egreg May 28 '14 at 10:39
  • I have installed the latest TeX Live distribution and the error remains. I have added the listfiles output. – Quarticle May 28 '14 at 20:58
  • Now the file list is the same, but I don't get any error. – egreg May 28 '14 at 21:23
  • Do you have any suggestions as to where the problem might be? – Quarticle May 28 '14 at 21:27
  • Sorry, no. An extraneous invisible character? – egreg May 28 '14 at 21:34
  • I do think it is a reproducible problem. I did a full install of TeX Live on a different computer. The only things I did were to install TeX Live and make the example files described. Running latex main.tex gives no problem. Running latex sub1.tex gives the error described. – Quarticle Jul 07 '14 at 14:43
  • The problem seems to be in newtxtext. – egreg Jul 07 '14 at 15:10

the newtxtext package loads etoolbox package which redefines \@@end. It really shouldn't do that. Since it does you can do this to locally restore it.

\makeatletter
\let\@@@@@@end\@@end
\def\fixend{\let\@@end\@@@@@@end}
\makeatother
\documentclass[main]{subfiles}
\begin{document}
$\fixend\bm{x}$
\end{document}

    Note that it's etoolbox that redefines \@@end – Joseph Wright Jul 07 '14 at 15:51
  • @JosephWright is it? OK thanks I'll re-apportion blame:-) – David Carlisle Jul 07 '14 at 15:55
  • Notice the patch: \patchcmd\enddocument {\deadcycles} {\let\AfterEndDocument\@firstofone \@afterenddocumenthook \deadcycles} {} {\let\etb@@end\@@end \def\@@end{% \let\AfterEndDocument\@firstofone \@afterenddocumenthook \etb@@end}} only alters \@@end if the initial patch of \enddocument fails. – Joseph Wright Jul 07 '14 at 15:57
  • @JosephWright presumably subfiles has made "only inside end document" to be rather more places:-) – David Carlisle Jul 07 '14 at 15:58
  • Slight correction: it only makes the change to \@@end if \enddocument has been altered, which is what happens with subfiles. – Joseph Wright Jul 07 '14 at 16:01
