When using the subfiles package, is there some command to get the main document's name, even when compiling one of the child documents?

Here's a MWE showing what I mean:

RequirePackage{filecontents}

%

begin{filecontents*}{main.tex}

documentclass{article}

usepackage{subfiles}

end{filecontents*}

%

documentclass[main.tex]{subfiles}

begin{document}

Child document's name: jobname % this displays 'Child document's name: <the_name_you_gave_to_this_document>



Main document's name: % <some_command>  -- this should display 'Main document's name: main'

end{document}

Where <some_command> is the command I'm looking for.

The option you pass to the subfiles class is stored in preamble@file, which is later input by the class. To get the base name of the file you can use LaTeX's filename@parse, which will store the base name in filename@base:

RequirePackage{filecontents}

%

begin{filecontents*}{main.tex}

documentclass{article}

usepackage{subfiles}

makeatletter

letnoibe@ifloaded@ifl@aded

defmainfilename{%

  noibe@ifloaded{cls}{subfiles}%

    {filename@parse{preamble@file}filename@base}

    {jobname}%

}

makeatother

begin{document}

Child document's name: jobname % this displays 'Child document's name: <the_name_you_gave_to_this_document>



Main document's name: mainfilename % -- this should display 'Main document's name: main'

end{document}

end{filecontents*}

%

documentclass[main.tex]{subfiles}

makeatletter

letnoibe@ifloaded@ifl@aded

defmainfilename{%

  noibe@ifloaded{cls}{subfiles}%

    {filename@parse{preamble@file}filename@base}

    {jobname}%

}

makeatother

begin{document}

Child document's name: jobname % this displays 'Child document's name: <the_name_you_gave_to_this_document>



Main document's name: mainfilename % -- this should display 'Main document's name: main'

end{document}

The command checks if the loaded class is subfiles. If it is, you're in a child file and the main file name is stored in preamble@file. Otherwise you're in the main file and the file name is jobname itself. When you're in the main file the command preamble@file does not exist, so the command checks which class is loaded and acts accordingly.

makeatother

begin{document}

Child document's name: jobname % this displays 'Child document's name: <the_name_you_gave_to_this_document>



Main document's name: mainfilename % -- this should display 'Main document's name: main'

end{document}

end{filecontents*}

%

documentclass[main.tex]{subfiles}

makeatletter

letnoibe@ifloaded@ifl@aded

defmainfilename{%

  noibe@ifloaded{cls}{subfiles}%

    {filename@parse{preamble@file}filename@base}

    {jobname}%

makeatother

Child document's name: jobname % this displays 'Child document's name: <the_name_you_gave_to_this_document>
