nvim 0.10 introduces
vim.fs.root, which
basically replaced the need for a rooter-plugin for me. Automatically setting
the root is now trivial: The snippet below sets the cwd to the parent of the
buffer that has a .git or Makefile.
1vim.api.nvim_create_autocmd("BufEnter", {
2 callback = function(ctx.buf)
3 local root = vim.fs.root(ctx.buf, {".git", "Makefile"})
4 if root then vim.uv.chdir(root) end
5 end,
6})
