[BUG] Import statements are not detected

[Kim-Vallee]

Description

Import statements in documents do not detect the associated files. To be more precise, the files detected which contain input statements do not detect the further inputted files.

Steps to reproduce

A main file main.tex with:

\documentclass[a4paper]{article}

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[english]{babel}

% figure support
\usepackage{import}

\begin{document}
	\import{content/my_content/}{my_content}
\end{document}

A secondary file content/my_content/my_content.tex with the content like:

\section{This is a section you can click on} \label{sec:this_is_a_section_you_can_click_on}

\input{more_content}

A last file content/my_content/more_content.tex with:

Here is my text ! Try click on it and it won't work ;(

Expected behavior

It should be that the file content/my_content/more_content.tex appears in the vimtex, for instance to allow for inverse search.
More precisely, I remark that section (from the import) is "inversesearchable" but not the text (from the input in the import).

Actual behavior

As of now the file content/my_content/more_content.tex is not detected by vimtex.

Do you use a latexmkrc file?

No

The example you provide does not compile. It might not be fully relevant to the issue, but since you are mentioning inverse search I thought it useful to mention it.

I've looked into this, and I'm sorry to say it is quite hard to figure out a fix for it. I've not given up on it yet, though.

A couple of notes to my future self:

• I think the problem here is that I need to recursively change the root for \imported files while parsing.
• I think the same holds for \subfile.
• I think I need to change the output of vimtex#parser#tex#input_parser to yield both the file it finds and the root for that file.

The example you provide does not compile. It might not be fully relevant to the issue, but since you are mentioning inverse search I thought it useful to mention it.

Edited, I've made a full blown example now (not only parts)

[Kim-Vallee]

Additional note: this also impacts the ToC (but this was expected).

Maybe surprisingly (I have not dug into the code of vimtex yet), but :VimtexView seems to work properly.

[lervag]

I think I found a solution to this now. I'm pushing an update in a couple of minutes. Thanks for raising the issue!

[Kim-Vallee]

Thanks, however for some reason it does not seem to work systematically, sometimes yes, sometimes not.
Is there a way to activate the logs ? I would be able to provide a more complete report.

[lervag]

Sorry, I think the best approach here is to create additional examples of cases where it doesn't work. I'm trying to add tests for the cases first, so this is very valuable as input.

[Kim-Vallee]

I will do this when I have time, since my original document is way too long and intricate to put as an example.

[Kim-Vallee]

Sorry for the long time, I found the template I was using.
You can clone the following repo, and on my side only the following source files are detected:

  source files:
    main.tex
    setup.tex
    content/front/titlepages.tex
    content/front/copyright.tex
    content/front/remerciements.tex
    content/front/abstract-en.tex
    content/front/abstract-fr.tex
    content/introduction.tex
    content/soa/soa.tex
    content/contributions/contributions.tex
    content/evaluation/evaluation.tex
    content/conclusion.tex
    appendix/resume-fr.tex

[lervag]

That's strange. On my side, the following are available:

VimTeX project: main
  base: main.tex
  ...
  source files:
    main.tex
    setup.tex
    content/front/titlepages.tex
    content/front/copyright.tex
    content/front/remerciements.tex
    content/front/abstract-en.tex
    content/front/abstract-fr.tex

    content/evaluation/eval3.tex
    content/evaluation/eval4.tex
    content/evaluation/discussion.tex
    content/conclusion.tex
    appendix/resume-fr.tex

I checked and found that this should be every single included file.

Are you sure you actually updated VimTeX? I think the files missing on your end are precisely the files that were missing before and that my recent commit should have fixed.
