Vim: open a file based on a git command

Question

Goal: map <localleader>n to open "$(git rev-parse --show-toplevel)/notes.md"

I know how to do mappings, and the above git command works fine on the command line. Marrying the two together in vim has been surprisingly hard.

I tried running vim commands like this: :e system("$(git rev-parse --show-toplevel)/notes.md"), but that just opens a file called "system(".

I'll take a vimscript solution, though a lua solution is slightly more preferable.

backticks should work, e.g. `:e \`git rev-parse --show-toplevel\`/notes.md` — MarcoLucidi, Jan 20 '22 at 16:57

This line in my lua init file works. Backticks are the secret sauce:

vim.api.nvim_set_keymap(
  'n',
  '<localleader>n',
  ':e `git rev-parse --show-toplevel`/notes.md<CR>',
  { noremap = true, silent = true }
)
