Highlight of delimiters is lose after passing to another file in arg list

[Aster89]

I use tikz with externalization.

When I open multiple files with vi main.tex graph.tikz, the delimiters (\begin{...} ... \end{...}) are correctly highlighted and % correctly jumps from upper to lower delimiter; when I pass to the other file with :n, there the delimiter \begin{tikzpicture} ... \end{tikzpicture} is highlighted and % still works; when I come back to the original file with :N the delimiters are no more highlighted, while % still works well.

The .latexmkrc file contains

$pdflatex = 'pdflatex --interaction=nonstopmode --shell-escape --synctex=1';
add_cus_dep('tikz', 'pdf', 0, 'maketikz');

[Aster89]

It seems that <localheader>lx restores the correct behavior at least for .tex files.

[lervag]

Can you please provide a full minimal example, and at least a minimal vimrc file?

[Aster89]

Well, the problem is present whichever the files, so I tried with the following main.tex file

\documentclass{article}
\usepackage{amsmath} % just to put the equation environment in the other file
\begin{document}
Hello!
\input{other.tex}
\end{document}

and the other.tex file

\begin{equation*}
x = y
\end{equation*}

I can open the two files with vi main.tex other.tex or vi other.tex main.tex. In each case, when I move from the first one to the second one (with :n) and then back to the first one (with :N or :first), then the coloring of the environments in the first file is lost. The same happens if I split the window to see the two buffers at the same time, with the only addition that before the first move from the first file to the second, I can move the cursor on the environment to highlight it. Then, when I move to the second file, the coloring of the environment in the first files remains blocked (also when I move the cursor).

The complete .vimrc file is the following (I have no idea of which part could be important and which not).

Please see the issue description, and in particular the minimal vimrc template:

set nocompatible

" Load Vimtex
let &rtp  = '~/.vim/bundle/vimtex,' . &rtp
let &rtp .= ',~/.vim/bundle/vimtex/after'

" Load other plugins, if necessary
" let &rtp = '~/path/to/other/plugin,' . &rtp

filetype plugin indent on
syntax enable

" Vimtex options go here

Adjust the template according to your own settings (necessary vim and vimtex options, correct paths, etc), then save the file as minivimrc or similar. Finally, open with vim -u minivimrc main.tex other.tex.

[lervag]

I notice two things from your vimrc file: You set no vimtex options. This might be OK. You set options for LaTeX-Suite. This plugin does NOT work together with vimtex, and if you by chance have this plugin installed, e.g. on a system level, then it will conflict.

[Aster89]

Oh, I simply forget to remove those lines from the .vimrc file. Now it's ok. For what concerns the installation of the plugin, I installed it following instructions on the LaTeX-Suite website (I was very very new to the Vim world and in particular I was new to plugins; now I use Vundle to install plugins), so I tried to remove every file LaTeX-Suite-related manually. I think I successfully deleted them all.

[lervag]

Good. Still, if you want me to investigate this, you have to create a minimal vimrc file that reproduces the problem. I don't have the time to debug your vimrc file for you, so if the problem can not be isolated to vimtex, then you will have to debug this yourself.

Note: It is really quite simple. My template for the minimal vimrc file should mostly just work out of the box.

[Aster89]

Ah, okok, then I'll try in a moment.

[Aster89]

Tried. The problem persists.

[lervag]

Can you post the minimal vimrc file you tried?

Can you report the version of Vim you are using (after you've opened, do :version).

[Aster89]

I just substituted my .vimrc with yours.

Does the same happen if you use vim instead of vi?

Ah, ok, I finally reproduced it. I'll investigate.

Think that should do the trick. Let me know if it works!
