Errors E716 E116 when running :VimtexTocOpen in a file containing a \label about vimtex

[lervag]

First of all, thank you so much for this wonderful vim plugin! I couldn't think of writing .tex files without it.

Thanks for the kind words!

It's my first time opening a ticket on github, I hope the description will be to your liking! Please, tell me otherwise.

Yes, this is a good first ticket! Nice to see that you're using proper formatting and everything!

Two errors (E716, E116) come up when running :VimtexTocOpen (or :VimtexTocToggle) in a file containing some \label commands. The commands run smoothly in the same file without the \label.

Here is the error log:

Error detected while processing function 356[12]..361[5]..vimtex#parser#toc[13]..vimtex#parser#toc#parse[65]..509:
line    4:
E716: Key not present in Dictionary: "format, l:key, l:label), 'number' : '', 'file'   : a:context.file, 'line'   : a:context.lnum, 'level'  : a:context.max_level - a:context.level.current, 'rank'   : a:context.lnum_total, 'type'   : 'label', }"

I can't reproduce this on my end. I've made a minor patch that might fix it. Before you update and test, please read my next reply and see if you can still reproduce with an updated minimal config.

It is relatively recent, and persists even when checking-out older commits. I therefore think it's because of my system, but I can't find the reason why, nor can debug vim scripts :'(

I tried with a minimal vimrc file, no other plugins, and with a minimal.tex file as well.

1. `vim -Nu "vimrc" mimimal.tex`
2. Run `:VimtexTocOpen` ---> fails

Can you try and reproduce with vim --clean -u test.vim minimal.tex instead; where test.vim is as given here:

set nocompatible
set runtimepath^=~/.vim/plugged/vimtex
set runtimepath+=~/.vim/plugged/vimtex/after
filetype plugin indent on
syntax enable

Can you still reproduce your problem now?

System info:
  OS: Debian GNU/Linux 11 (bullseye)
  Vim version: VIM 8.2 (1-2434)
  Has clientserver: true
  Servername: undefined (vim started without --servername)

Just in case you didn't already know of it, you should read :help vimtex-clientserver.

Hi,

Thanks you for your quick reply and your feedback!

I reproduced the steps you described, and I still got the error, but your patch fixed it! Thank you so much for your assistance, that's really wonderful.

Thanks again!

Oh thanks, I will look into the vimtex-clientserver documentation, I'm not sure what it is.

I went ahead and closed the ticket, is this OK?

Cheers

Glad to hear it! It is still surprising to me that you could reproduce the problem, but let's not spend more energy on it if it works now :)

Yes, perfect. And feel free to open new issues if you have other questions or problems.
