I would like to find the git root directory and use it as argument for
:FZF in a key mapping like this:
nnoremap <Leader>eg :FZF `git rev-parse --show-toplevel`<CR>
Unfortunately, this does not work. If I understand it right, backtick expansion works only when vim expects a filename. I think
:FZF expects a folder name but maybe vim doesn't know this.
How can this be done?
