init error when opening a .sty file

[verga]

Hi! I get the error message

"min.sty" 3L, 62C
Error detected while processing function vimtex#init[39]..<SNR>57_init_mappings:

line   94:
E716: Key not present in Dictionary: viewer, 'reverse_search')
E116: Invalid arguments for function has_key(b:vimtex.viewer, 'reverse_search')
E15: Invalid expression: has_key(b:vimtex.viewer, 'reverse_search')

when trying to open a .sty file.

Minimal example:

min.sty:

\NeedsTeXFormat{LaTeX2e}                                                   
\ProvidesPackage{varticle}                                                 
\endimput 

.vimrc

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

The command vim min.sty gives the error.

Strange. I can't reproduce. I did vim -u minivimrc min.sty, where minivimrc is the name I used for the minimal vimrc file.

Are you using the latest version of vimtex? Which version of Vim are you using?

[clason]

I can reproduce this with vim8 (8.0.311) and neovim (0.1.7), if the minivimrc has the additional line au BufNewFile,BufRead *.cls,*.sty set ft=tex

and if I open the style file in a new window from a standard tex file:

1. vim -u minivimrc $ANY_TEX_FILE
2. <ctrl-w,n>
3. :e min.sty

I'am using the latest versions (from homebrew):

Try using the option

" Vimtex options go here
"
let g:vimtex_view_enabled = 1

added at the end of the minimal vimrc, and then the command vi -u .vimrc min.sty

[lervag]

g:vimtex_view_enabled is already set to 1 by default, so that option changes nothing. I still can not reproduce based on your input, @verga.

[lervag]

However, I can reproduce when following @clason's steps. Looking into it now.

[lervag]

Sorry, @verga, my fault. Setting the option really does make the error appear. I've understood the problem now, should be able to fix it pretty fast.

[clason]

That fixes the error on opening for me; but now I get an error on closing (which I think was already there before the fix; I just always focused on the first one). Same steps as above, followed by

4. <ctrl+w,q> (or )

yields
