I noticed 3 problems with my Vim terminal setup on Ubuntu which can be illustrated by the following picture of my current Vim. I get the same look with a lot of airline-themes (e.g. molokai, jellybeans, dark, etc.) current Vim

  • The first problem is that I'd like to have colors with my status bar which are clearly not appearing.
  • Also I don't know if the symbols of the status bar are correct, because the arrows do not look like the ones shown below. enter image description here
  • Finally the upper bar indicating the buffers or the tabs clearly do not look like mine.

Also, here are some potentially useful informations

  • I installed the powerline patched Mac OS font Monaco. This helped me to replace some weird symbols and get the ones shown above.
  • The only airline theme that was different was base16.
  • I tried changing the Vim colorscheme to different ones, but it didn't solve anything.

Finally here is a copy of my .vimrc

set encoding=utf8

set rtp+=~/.vim/bundle/Vundle.vim
let g:ycm_global_ycm_extra_conf = '~/.vim/bundle/YouCompleteMe/third_party/ycmd/cpp/ycm/.ycm_extra_conf.py'
call vundle#begin()

set laststatus=2
set completeopt-=preview

map <Tab> <C-W>W
nnoremap <F5> :NERDTreeToggle<CR>
:nmap <F3> :vimgrep //j ** <bar> copen

If more information is needed to solve these problems, I'll gladly provide it.

UPDATE: I solved the first two problems by putting 'set t_Co=256' in my .vimrc, but the upper bar is still the same is it normal?

I solved the first two problems by putting the set t_Co=256 in my .vimrc and solved the missing upper bar problem by putting this in my .vimrc.

let g:airline#extensions#tabline#enabled = 1
" Show just the filename
let g:airline#extensions#tabline#fnamemod = ':t'

    You shouldn't set t_Co=256. Instead, set TERM=xterm-256color (or if using screen/tmux, TERM=screen-256color) in your shell initialization files.

  • The contributor said: "vim should detect this value automatically, but only if you have your terminal set up properly". Setting your terminal up properly is having TERM=xterm-256color. Having done that, Vim will detect that t_Co should be 256. It's if you have TERM supporting 256 colors and Vim doesn't detect it that you have to use this override.

  • @muru Will try that, but why shouldn't I set it as it is suggested here to enable 256 colors in Vim?
