Do you happen to know if neovim has a helm-ag analog? For the most part that and magit are the only two things I use in emacs anymore and would love to try something lighter weight.

There's vim-grepper but nothing really has a selection interface quite like Helm.

I use telescope.nvim + ripgrep for what I believe is the same functionality

Neogit is a magit clone rather than secretly actually using magit code, right?

At least until they add an elisp interpreter to vim.
