Minimal vimrc that can reproduce this bug.

packadd! gruvbox-material
" Important!!
if has('termguicolors')
  set termguicolors
endif

" For dark version.
set background=dark

" For light version.
" set background=light

" Set contrast.
" This configuration option should be placed before `colorscheme gruvbox-material`.
" Available values: 'hard', 'medium'(default), 'soft'
let g:gruvbox_material_background = 'soft'

" For better performance 
let g:gruvbox_material_better_performance = 1

colorscheme gruvbox-material

Steps to reproduce this bug using minimal vimrc

1. create empty .vim
2. clone/add submodule: git submodule add --depth=1 https://github.com/sainnhe/gruvbox-material.git pack/colors/opt/gruvbox-material
3. start vim

Expected behavior

lovely gruvbox colours

Actual behavior

nothing until you press Ctrl-C at which point the following appears:

➜  ~ vim .vim/vimrc
^CError detected while processing /Users/coliny/.vim/vimrc[21]../Users/coliny/.vim/pack/colors/opt/gruvbox-material/colors/gruvbox-material.vim:
line 1423:
Interrupted
Error detected while processing /Users/coliny/.vim/vimrc:

Interrupt: Press ENTER or type command to continue

NOTE: removing let g:gruvbox_material_better_performance = 1 makes everything work.

I just tried in a fresh Debian container using this exact .vimrc and plugin (pack) cloned into the same location.

It took Vim a couple of seconds to generate the syntax files on the first startup, but it eventually completed:

After starting Vim, could you please keep checking, in a separate terminal, whether the contents of the ~/.vim/pack/colors/opt/gruvbox-material/after/syntax/ directory is being populated?

Ah OK - I wasn't waiting long enough. Yes, letting it finish (few seconds) works perfectly. Thanks!

[antoineco]

Glad it completed eventually!
