Preamble isn't folded, although `let g:latex_fold_preamble = 1` is set about vimtex

Interesting. This does not happen with me. Do you set the foldlevel somewhere? Try :verbose set foldlevel to see where it was set the last time.

:verbose set foldlevel yields foldlevel=0

Notice, I also tried this in gvim which does show the same behaviour

[lervag]

Strange. I have no idea what causes this. Could you try to create a minimum working example? What version of vim are you using?

[nasenatmer]

Here's a minimum working example which shows the same behaviour:

\documentclass{scrartcl}
\usepackage{biblatex} % one additional line to \documentclass is necessary for folding to happen
\begin{document}
\section{Intro}
Hello
\end{document}

I Included a section to test whether automatic folding at startup works or not. My vim version is the current one from Archlinux, 7.4.459

I also used this mini vimrc, same result. Additionally, I renamed my ftplugin/tex.vim so it doesn't get sourced, but still no change.

But if it works for you and as this still is just a minor problem that actually might be local to my machine only, I think we shouldn't spend too much effort on this. Except if you have any quick idea, I'd be happy to help…

Thanks, your MWE reproduces the problem for me. If I add a line above the documentclass, then the problem goes away. I'll investigate further when I get some time. In the meantime, you could add a simple comment as your first line.

[lervag]

This very simple commit seems to fix the issue. Let me know if it works for you as well.

[nasenatmer]

Indeed. Empty first line solves the problem. Thats a good workaround for the the time being! Do you always have empty or commented first lines?

[lervag]

Haha, sorry, I just forgot to push. Try the latest version.

[nasenatmer]

Works, nice one! Thanks a lot!

[lervag]

Great!
