Warning message on neovim startup

[TriupLauro]

Preamble (you can delete this section):

• Are you using a recent build (november 2020 & up) of neovim 0.5?
• If not, rebuild it now before reporting the issue.
• Do you certify having read the readme or are ready for being shamed for not having read the manual?

Description

On opening neovim I am greeted with this warning

Erreur détectée en traitant /home/valou/.local/share/nvim/plugged/barbar.nvim/pl
ugin/barbar.lua :
W18: Caractère invalide dans un nom de groupe

(In english it would be "invalid charecter in group name")

Output of nvim -v

NVIM v0.7.2
Build type: Release
LuaJIT 2.1.0-beta3
Compilé par [email protected]

To Reproduce

init.vim:

call plug#begin()

Plug 'romgrk/barbar.nvim'

call plug#end()

Steps to reproduce the behavior: Install barbar nvim through vim-plug

Launch neovim

Informations Neovim version: v0.7.2

I will investigate this. We intend to support Neovim 0.7.2, but my impression is that this is a backwards compatibility issue, so updating Neovim will likely fix it for now.

I also encountered this problem using neovim v0.7.2 on centOs7, but the error information is different.

W18: Invalid character in grop name

Any way you can upgrade neovim?

[Iron-E]

This is a nvim-web-devicons issue. I'd suggest pinning the version you use using your plugin manager, or disabling file icons.

Closing as while we want barbar to be compatible with Neovim 0.7.2, we can't guarantee the same of our integrations.

Thanks for debugging. Indeed disabling icons remove the warning. I'll try opening an issue on nvim-web-devicons.
