Ask to create non-existant directories upon saving a new file


If you edit a new file: vim these/directories/dont/exist/newfile, you won't be able to save the file as the directory vim is trying to save into does not exist.

Prompt to create directories with :w, or sliently create them with :w!

This code will prompt you to create the directory with :w, or just do it with :w!:

augroup vimrc-auto-mkdir
  autocmd BufWritePre * call s:auto_mkdir(expand('<afile>:p:h'), v:cmdbang)
  function! s:auto_mkdir(dir, force)
    if !isdirectory(a:dir)
          \   && (a:force
          \       || input("'" . a:dir . "' does not exist. Create? [y/N]") =~? '^y\%[es]$')
      call mkdir(iconv(a:dir, &encoding, &termencoding), 'p')
augroup END
