【Vim】Setting to make renaming a file during editing easier with a shortcut

#vim #vimrc #linux #webdev

Introduction

When I want to do file renaming even when editing vim, I was wondering if it is possible because of the following points.
- I don't want to use a long command, but a shortcut using key bindings.
- If I forget to save a command like :w, I want to save it automatically.
- I want to perform a process interactively.
So, I'll write a simple setting for renaming with the Leader.

Result

Open .vimrc (configuration file)

vim ~/.vimrc

Write the following to .vimrc.

" setting leader
" Use 「Space + other keys」.
let mapleader = "\<Space>"

" Calling a renaming function
" Enables the renaming process in the vim with 「space + n」.
map <leader>n :call RenameCurrentFile()<cr>

" Define the renaming function
function! RenameCurrentFile()
  let old = expand('%')
  let new = input('NewFileName: ', old , 'file')
  if new != '' && new != old
    exec ':saveas ' . new
    exec ':silent !rm ' . old
    redraw!
  endif
endfunction
