Undefined variable: g:bufferline

[mawkler]

I tried to disable the close buttons using g:bufferline.closable but I'm getting the error E121: Undefined variable: g:bufferline when Neovim launches. What am I doing wrong? The following is my minimal config:

call plug#begin('~/.vim/bundle')
Plug 'kyazdani42/nvim-web-devicons'        " Required by barbar.nvim
Plug 'romgrk/lib.kom'                      " Required by barbar.nvim
Plug 'romgrk/barbar.nvim'                  " Sexiest buffer tabline
call plug#end()

let g:bufferline.closable = v:false

Barbar hasn't run yet so it's not defined yet. You can define it yourself with let bufferline = { 'closable': v:false }, barbar will respect that setting because he's polite. Oh and also the latest version of barbar doesn't depend anymore on lib.kom so you can delete the line.

Oh of course! I figured doing let g:bufferline = { 'closable': v:false } would remove all other default settings in bufferline but I see now that barbar.nvim is smarter than that. Thanks!
