This isn't outside the scope, I've been thinking about implementing something like this.

Something I'm a little more interested in is showing signs for changes that are staged which would be useful if you like staging individual hunks which I personally do all the time. So essentially a diff of HEAD against index.

This suggestion is more of the lines of diffing tree against index

Actually I found this plug:

• https://github.com/chrisbra/changesPlugin - it does work but user has to enable it manually each time, and it does not have as rich customization as gitsigns but works ok (non lua though). Maybe it could be used for inspiration :)

I found this plugin: footprint which is good enough for my needs. I will close this then.

Using footprint is probably a better option since the requirement of signs for modified lines doesn't require git.

After some talk on Matrix, I'd like to reconsider this at some point.

Thx levis, somone figured out how to use it?
Something like:
autocmd IF_Buffer_Not_Tracked : attach(bnumb, ctx = {base='FILE'} ?

https://github.com/lewis6991/gitsigns.nvim/blob/61e0130d4bd255d4a447656ec6e6c11bfeeb20a4/doc/gitsigns.txt#L104C1-L104C1
317c98d

For now I get something like this :

local git_non_tracked = vim.api.nvim_create_augroup("GitSignTrackNonTracked", { clear = true })
vim.api.nvim_create_autocmd({ "BufEnter"}, {
  pattern = "*",
  callback = function()
    print('attaching gitsigngs')
    gitsigns.attach(0, {
      file = vim.fn.expand("%:p"),
      toplevel = vim.fn.expand("%:p"),
      base = 'FILE' })
  end,
  group = git_non_tracked,
})

But it does not seem to work. And I have to find way to detect non tracked buffer/files only. ..

The files still need to be within a git repo for this to work, otherwise gitsigns can't attach.
