hi,

my plugin are broken after update.

when i start vim i have this :

Error detected while processing function <SNR>46_airline_refresh[11]..airline#load_theme[16]..airline#update_statusline[18]..<SNR>56_invoke_funcrefs[2]..airline#util#exec_funcrefs[2]..AirlineWebDevIcons:

my config :

let g:airline#extensions#tabline#enabled = 1
let g:airline_powerline_fonts = 1
let g:airline_theme='solarized'

[chrisbra]

can you find out, which commit broke it? Please provide a minimal example that breaks it (i see you are using the webdevicons plugin). What is your airline version and vim version?

[chrisbra]

Also I wonder why your g:airline_section_x is not defined. That should always exist

[chrisbra]

The problem comes from the webdevicons plugin, so I just created a patch for that. Anyhow, I still wonder how you managed to unset the g:airline_section_x variable.

[ghost]

thanks for reactivity,

i don't unset g:airline_section_x variable.
but she's not in my vimrc

[chrisbra]

well, please provide a minimal example that reproduces the issue.

[ghost]

fixed with this let g:airline_section_x = '' in my vimrc

[chrisbra]

that shouldn't be necessary. It is initialized here
That's why I asked, please provide a minimal example to reproduce your issue

[ghost]

how i can provide example ?

that's strange, when i start vim without let g:airline_section_x = ''

i have this error message

Error detected while processing function <SNR>46_airline_refresh[11]..airline#load_theme[16]..airline#update_statusline[18]..<SNR>56_invoke_funcrefs[2]..airline#util#exec_funcrefs[2]..AirlineWebDevIcons: line 1: E121: Undefined variable: g:airline_section_x E116: Invalid arguments for function get(w:, 'airline_section_x', g:airline_section_x) E15: Invalid expression: get(w:, 'airline_section_x', g:airline_section_x) line 2: E121: Undefined variable: w:airline_section_x Error detected while processing function <SNR>46_airline_refresh[12]..airline#update_statusline[18]..<SNR>56_invoke_funcrefs[2]..airline#util#exec_funcrefs[2]..AirlineWebDevIcons: line 1: E121: Undefined variable: g:airline_section_x E116: Invalid arguments for function get(w:, 'airline_section_x', g:airline_section_x) E15: Invalid expression: get(w:, 'airline_section_x', g:airline_section_x) line 2: E121: Undefined variable: w:airline_section_x

but everything works properly when i skip this message

[chrisbra]

well, it must depend on your configuration/plugins, etc. So what is the minimal needed configuration to reproduce this problem?

[ghost]

call plug#begin('~/.vim/plugged')

if has('nvim')
  Plug 'Shougo/deoplete.nvim', { 'do': ':UpdateRemotePlugins' }
else
  Plug 'Shougo/deoplete.nvim'
  Plug 'roxma/nvim-yarp'
  Plug 'roxma/vim-hug-neovim-rpc'
endif
" Use deoplete.
let g:deoplete#enable_at_startup = 1

Plug 'vim-airline/vim-airline'
Plug 'vim-airline/vim-airline-themes'
Plug 'ryanoasis/vim-devicons'

call plug#end()

[chrisbra]

so this only happens with neovim?

[chrisbra]

if I use this config, I get this message:

Messages maintainer: Bram Moolenaar <Bram@vim.org>
[vim-hug-neovim-rpc] failed executing: pythonx import neovim
[vim-hug-neovim-rpc] Vim(pythonx):Traceback (most recent call last):

and when I try this with neovim I get:

[deoplete] Vim(call):E117: Unknown function: _deoplete_init
[deoplete] function deoplete#enable[1]..deoplete#initialize[1]..deoplete#init#_initialize[19]..deoplete#init#_channel, line 17
[deoplete] deoplete requires Python3 support("+python3").
[deoplete] deoplete failed to load. Try the :UpdateRemotePlugins command and restart Neovim. See also :CheckHealth.

Neither of those is the mentioned airline error :(

[ghost]

i use vim 8 not neovim

yesterday i have this issue too :

[deoplete] function deoplete#enable[1]..deoplete#initialize[1]..deoplete#init#_initialize[19]..deoplete#init#_channel[10]..yarp#core#notify[1]..yarp#core#wait_channel[5]..yarp#core#jobstart[2]..yarp#pyx#init[13]..yarp#core#serveraddr[1]..neovim_rpc#serveraddr, line 15

when i remove deoplete, dont have error with airline

possible conflict with deoplete ?

[chrisbra]

possible BTW: are you sure, that those two plugins

  Plug 'roxma/nvim-yarp'
  Plug 'roxma/vim-hug-neovim-rpc'

should be loaded in vim?

[ghost]

i restore old backup and fixed it, i think I did something wrong.

thanks for the time that you granted me.

[ghost]

im come back after PlugUpdate last update of vim-airlines and vim-airlines theme the same issue.

i think there is a conflict with vim-airline, deoplete and vim-devicons...

in the meantime I place let g:airline_section_x = '' in my vimrc and is ok
