I'll start by saying that I never wrote any VimScript or done any advanced configuration in my .vimrc. I'm a super noob 😅. Bear with me.

I've been trying to backup my VimWiki on Git. I want to add some redundancy to the Dropbox setup already in place.

I've been following the instructions here:

augroup vimwiki
au! BufWritePost ~/vimwiki/* !git add "%";git commit -m "Auto commit of %:t." "%"
augroup END

For my first test, I saved the wiki index. I got this error:

!git add "/Users/gio/Dropbox/vimwiki/markdown/index.md"
fatal: /Users/gio/Dropbox/vimwiki/markdown/index.md: 
  '/Users/gio/Dropbox/vimwiki/markdown/index.md' is outside repository  at '/Users/gio/dotfiles'

Where /Users/gio/dotfiles is the folder from where I opened Vim.

If I cd to /Users/gio/Dropbox/vimwiki, saving the file results in the commit. But that's annoying, I'd like to be able to open the wiki from anywhere and commit and push the changes on every save.

I tried to add a pushd and popd to the mix, like this:

" Backup on Git
function CommitChangeInWiki()
  !pushd ~/Dropbox/vimwiki
  !git add "%"
  !git commit -m "Auto commit of %:t." "%"
  !popd
endfunction

au! BufWritePost ~/Dropbox/vimwiki/**/* call CommitChangeInWiki()

It doesn't work, though. I can see that pushd is called.

I'm clearly missing something here. Thanks for your help.

  • Ben already gave a good answer. Anyway: In Vim you can use :cd <path> and :cd - to jump back.

The pushd won’t work because it happens in a temporary shell. You could use cd && ..., but the best (I think) is git -C dir command, which makes git run in the provided directory.

  • Thank you @D. Ben Knoble. It took me a while to reply to you because I was experimenting this setup on my spare setup... Anyways, this works thank you :) One thing I'm not sure about is that it worked in the function syntax, but not in one liner one.
