Add Git integrations, show status badges on modified files or stage/unstage by actions, etc.

[timsofteng]

Hello. Fern is very cool file tree. It's quick and flexible. Can you please implement git integration to it? I mean flags like modified, deleted, added, etc.
Thanks.

I've been dreaming such features but it's not easy while I'd like to keep the plugin simple and quick. So it would take loooong time to provide such feature.

[timsofteng]

It's sad. This is only feature I miss after NERDtree.

[lambdalisue]

I may misunderstood the feature so it would be nice if you explain the feature with some screenshot/screencast in this issue so that people (including me) do not need to install and try NERDTree and its git integration.

[timsofteng]

I think for berer understanding you could just look at this nerdtree plugin:

https://github.com/Xuyuanp/nerdtree-git-plugin

It's what I mean.

Maybe it integrates with gitgutter plugin. I don't know.

This is git status integration for defx: https://github.com/kristijanhusak/defx-git
The icons on the left of each tree node mark the git status.

@rafi I like your indicator. Could you share the config like below?

call defx#custom#column('git', 'indicators', {
  \ 'Modified'  : '✹',
  \ 'Staged'    : '✚',
  \ 'Untracked' : '✭',
  \ 'Renamed'   : '➜',
  \ 'Unmerged'  : '═',
  \ 'Ignored'   : '☒',
  \ 'Deleted'   : '✖',
  \ 'Unknown'   : '?'
  \ })

And colors?

hi Defx_git_Untracked guibg=NONE guifg=NONE ctermbg=NONE ctermfg=NONE
hi Defx_git_Ignored guibg=NONE guifg=NONE ctermbg=NONE ctermfg=NONE
hi Defx_git_Unknown guibg=NONE guifg=NONE ctermbg=NONE ctermfg=NONE
hi Defx_git_Renamed ctermfg=214 guifg=#fabd2f
hi Defx_git_Modified ctermfg=214 guifg=#fabd2f
hi Defx_git_Unmerged ctermfg=167 guifg=#fb4934
hi Defx_git_Deleted ctermfg=167 guifg=#fb4934
hi Defx_git_Staged ctermfg=142 guifg=#b8bb26

@lambdalisue sure:

You can also find nice custom commands I wrote: https://github.com/rafi/vim-config/blob/master/config/plugins/defx.vim

Also, I'm currently testing this autocmd to refresh opened/closed defx buffers when moving between windows of different lcd:

" Handle working-directory changes appropriately
autocmd DirChanged * if bufwinnr('tab'.tabpagenr()) != -1
	\ |   let cw = winnr()
	\ |   Defx -toggle -buffer-name=tab`tabpagenr()`
	\ |   execute('lcd ' . v:event['cwd'])
	\ |   Defx -toggle `getcwd()` -buffer-name=tab`tabpagenr()`
	\ |   execute(cw . 'wincmd w')
	\ | elseif bufnr('tab' . tabpagenr()) != -1
	\ |   execute(bufnr('tab' . tabpagenr()) . 'bwipeout')
	\ | endif

@lambdalisue So may i try this feature or it ins't ready yet?

[rafi]

@timsofteng you can track the progress at #124 - once that is merged, we could install https://github.com/lambdalisue/fern-badge-git.vim

[timsofteng]

@rafi oh, sure. got it

[lambdalisue]

@timsofteng @rafi
It's still under development but you can try https://github.com/lambdalisue/fern-plugin-git.vim with the latest fern.vim. Note that I'll use force push often to that repository so it's not stable.

[timsofteng]

@lambdalisue Thanks! I'll try it asap. I have few more questions about your plugin but i guess it's better to ask without opening issue. Could you please share your contact info like messenger or email?
Thanks.

[lambdalisue]

At least for now, it's better to open a new issue here if your question is related to fern.vim while other users can reply, see, or whatever. I probably avoid messages if you send it through a closed way like email, twitter DM, or whatever.
