vim + fzf.vim - specify project root in :Files

My question is about usage of vim-projectroot with fzf.vim

I have a key mapping which opens :Files at project root like this

nnoremap <leader>t :ProjectRootExe Files<CR>

But problem is it's interfering with set autochdir. Unless I force a new session with :e/:sp/:vsp current directory remains same as previous directory.

So I thought of passing directory as the second argument to :Files path like this

function Guess()
  return projectroot#guess()
endfunction

nnoremap <leader>t :Files Guess()<CR>

But for obvious reasons which I can't figure out I am unable to get the usage working. How can I specify in a vim mapping that it should combine the command with output of a function?

What I want is :Files output_of_Guess() to be invoked.

Vim's evaluation rules are different than most programming languages. You need to use :execute in order to evaluate a variable (or expression); otherwise, it's taken literally; i.e. Vim uses the function name itself as the argument.

nnoremap <leader>t :execute 'Files ' . Guess()<CR>

An alternative for mappings is using :help :map-expr; that's basically :execute built into the variant of :map:

nnoremap <expr> <leader>t ':Files ' . Guess() . "\<lt>CR>"
