How is automatic indentation done for subfiles with arara and latexindent?

Question

I guess that I have overlooked something, but I can't find a solution to run arara on my subfiles when processing my main file. I would like to autoindent my code but only succeed for the main.tex.

I installed latexindent.plx which works great. If I run % arara: indent: { overwrite : yes } on a single file document, everything works like expected.

In my actual documents the main.tex will look like this:

% arara: lualatex: { shell: yes }
% arara: indent: { overwrite : yes }
% arara: indent: { trace : yes }
\input{header}
\begin{document}
\include{chapter/foo}
\end{document}

For this solution, I get main.tex indented beautifully but not the header and not the chapters. As arara is looking for commands all over the source, I added another % arara: indent: { overwrite : yes } on top of some subfiles, but they don't effect the process. I would be glad for a hint, where my thinking error is.

First of all, thanks very much for trying latexindent :)

Your question is pretty much exactly the same idea as arara: making a rule to compile the main file from a chapter file and the trick is to tell arara which files you want to operate on.

As such, the following works as you want.

% arara: indent: { overwrite : yes, trace: yes, files: [ chapter/foo.tex, header.tex, chapter/bar.tex ]  }
\input{header}
\begin{document}
\include{chapter/foo}
\end{document}

Note that I have combined your two arara indent directives into one, otherwise you're running it twice- this shouldn't be necessary, and should probably be avoided. If latexindent does something wrong on the first pass, then the trace would have told you what happened on the second pass, which wouldn't have been very useful.
