Describe the feature

The Oil command should support a --in-git-root to set the cwd to the git repository root.

Provide background

I want to be able to easily configure a key mapping that opens oil in the root of the git repository.

What is the significance of this feature?

strongly desired

I'm currently using lspconfig to find the git ancestor, but it's not as nice.

This is what I use to open Oil in the git root of my buffer file.

vim.keymap.set("n", "_g", function()
  local git_path = vim.fn.finddir(".git", ".;")
  local cd_git = vim.fn.fnamemodify(git_path, ":h")
  vim.api.nvim_command(string.format("edit %s", cd_git))
  end, { desc = "edit .git root" })

If I wanted the keymap to also set the cwd to the git root, I would include vim.api.nvim_set_current_dir. So:

vim.keymap.set("n", "_g", function()
  local git_path = vim.fn.finddir(".git", ".;")
  local cd_git = vim.fn.fnamemodify(git_path, ":h")
  vim.api.nvim_command(string.format("edit %s", cd_git))
  vim.api.nvim_set_current_dir(cd_git)
  end, { desc = "edit .git root" })

Not sure if this is along the lines of what you are looking for.

Thanks @gregdezeeuw! That is the recommended solution for this. I won't be adding a special option for this, so creating your own custom binding for it is the way to go.
