Renaming the current file in Vim

Question

How should I rename my current file in Vim?

For example:

• I am editing person.html_erb_spec.rb
• I would like it renamed to person

Answer 1

This little script isn't perfect (the extra carriage-return you have to press) but it get's the job done.

function Rename()
  let new_file_name = input('New filename: ')
  let full_path_current_file = expand("%:p")
  let new_full_path = expand("%:p:h")."/".new_file_name
  bd    
  execute "!mv ".full_path_current_file." ".new_full_path
  execute "e ".new_full_path
endfunction                                                                                                                                                                                                                                 

command! Rename :call Rename()
nmap RN :Rename
