I have Fugitive vim and Airline vim installed via Vundle. I installed them as follow:

Plugin 'https://github.com/tpope/vim-fugitive.git'
Plugin 'vim-airline/vim-airline'

Airline status works fine. All of the functions in Fugitive works fine, such as Gcommit, Gpush... Now, I just want to have the name of the branch shows up on Airline. I've been searching around a lot, and most of the time, the problem is that doing :echo fugitive#head() does not show the correct branch. Mine works. It shows the correct branch. So, how to get it shows up in Vim Airline status bar? I tried: 152 let g:airline#extensions#branch#enabled = 1, this does not work.

I even tried to clean up entire .vim and .vimrc (start fresh from zero) and reinstalled Vundle, Fugitive, Airline... Still, the same problem occurs. What else do I need to add to my vimrc to make this works? Please let me know and thank you.

The .vimrc is as follow:

set nocompatible              " be iMproved, required
filetype off                  " required

" set the runtime path to include Vundle and initialize

  • Could you post here your minimal vimrc, the one that you're testing this on? Just to help us get same settings and check if it's reproducible. – klaus Mar 5 '19 at 7:13
  • I just did. Please see the vimrc – mle0312 Mar 5 '19 at 7:18
  • Strange! I'm able to reproduce the problem. Moreover it seems that fugitive-branch is shown when in netrw buffer. Can you confirm that? Just do :Ex and check if branch name shows up. – klaus Mar 5 '19 at 7:31
  • Yes, doing :Ex opens up a a tree-like directory of the Git directory that I am in. The Airline status bar shows: netrw, and the correct git branch. – mle0312 Mar 5 '19 at 7:34

    Airline maintainer here: please come up with a minimal reproducing example, you are currently overwriting the section_b which is supposed to display the branch name, so that explains why you are not seeing the branch extension. – Christian Brabandt Mar 5 '19 at 13:31
