Gruvbox Airline Vim

Question

I am trying to get the gruvbox airline theme working for my vim status line. I am using the plugged vim plugin manager and have added the gruvbox.vim airline theme to ~/.vim/plugged/vim-airline-themes/autoload/airline/themes.

EDIT: Realized I didn't source the 'vim-airline' plugin itself. I have added the following line to my .vimrc: 'vim-airline/vim-airline'

While the plugin is now working, the airline 'arrows' are not displaying. The information in the status line is simply separated by boxes, not arrows.

EDIT: I was able to get everything working properly (although a little hackish) by adding the following lines to my .vimrc:

" symbols section for unicode/airline symbols
let g:airline_powerline_fonts = 1

if !exists('g:airline_symbols')
    let g:airline_symbols = {}
endif

" unicode symbols
let g:airline_left_sep = '»'
let g:airline_left_sep = '▶'
let g:airline_right_sep = '«'
let g:airline_right_sep = '◀'
let g:airline_symbols.linenr = '␊'
let g:airline_symbols.linenr = '␤'
let g:airline_symbols.linenr = '¶'
let g:airline_symbols.branch = '⎇'
let g:airline_symbols.paste = 'ρ'
let g:airline_symbols.paste = 'Þ'
let g:airline_symbols.paste = '∥'
let g:airline_symbols.whitespace = 'Ξ'

" airline symbols
let g:airline_left_sep = ''
let g:airline_left_alt_sep = ''
let g:airline_right_sep = ''
let g:airline_right_alt_sep = ''
let g:airline_symbols.branch = ''
let g:airline_symbols.readonly = ''
let g:airline_symbols.linenr = ''

I am not sure what exactly I am doing wrong here. Thanks in advance for the help!

EDIT: Full working .vimrc with the Gruvbox airline theme looks like this:

Answer 1

If you use vim-plug add to your init.vim:

Plug 'morhetz/gruvbox'

Set colorscheme gruvbox

Save and quit. :PlugInstall, save and quit.

It should work. It comes with its own airline-theme natively and doesn't need the vim-airline-theme plugin.

See repo for more info.
