No git branch name

You should try to reproduce with a minimal vimrc.

Still having no idea. 😭

I reproduced with a very minimal vimrc. I was just using minpac plugin manager to install eleline. The branch name was still not shown.
Then I did some further investigation. Please take a look at this piece of code in eleline.vim (https://github.com/liuchengxu/eleline.vim/blob/master/plugin/eleline.vim#L94)

  if !exists('*FugitiveExtractGitDir')
    return ''
  endif

I added echom "aaaa" right above the return '' and in neovim I could see the output aaaa, which means the running fell into this if block, and it returns an empty string eventually. I am not sure whether or not this is the reason leading to the issue.

UPDATE:
I didn't install vim-fugitive because as the README said it is not required if I am using the latest neovim, right? However, based on the code itself, it seems that vim-fugitive is necessary. If vim supports the job feature, it will get the branch name asynchronously but vim-fugitive plugin should be installed no matter what, right?

Thank you very much.

Ok, the README is not very clear, eleline.vim will use the job feature to retrieve the git branch info when in a git repo, but the detection of the git directory is still dependent on the API of vim-fugitive.

[rockyzhang24]

Okay, so vim-fugitive is definitely required. I think it'd better update the README to make it clearer.

Thank you for your help.
