How to query neovim API for the current working directory?

Question

The neovim API provides nvim_set_current_dir(), but apparently does not expose a way to query cwd. How can I go about doing this?

Answer 1

old question, but I couldn't find the answer, so...
here it is; :lua print(vim.fn.getcwd())

ps; if you're using lsp, you may want to put it on on_attach; vim.api.nvim_set_current_dir(client.config.root_dir)
