Vim: moving files?

Currently if I'm editing a file and I decide that I want to rename it, I use:

:!mv % new.py
:new new.py
:bd

To rename the file, open the new file, then delete the old buffer.

Is there a simpler way to rename a file without leaving the old buffers hanging around?

(I rea开发者_JAVA百科lize that I could also use :sav, but then I would need to :bp a few times to find the previous buffer, :bd it, then :bn back to the new buffer)

I think you may be looking for this plugin.

It is a little plugin that does :saveas and removes the old file.

I think adding a plugin is much more complicated than what you're looking for. You could use a function to bind this functionality to a new command.

function! s:movefunction(arg)
  let oldnum = bufnr("%")
  let newname = a:arg
  execute "!mv %" . " " . newname
  exe "new " . newname
  exe "bd" . oldnum
endfunction

command! -nargs=* Newmv call s:movefunction('<args>')

After adding this to your .vimrc, you can then call this by doing

:Newmv new_file_name.py

---

You can also rename a file within the vim explorer move to the file you want to rename and press:

R

So that's:

1. Explore :E
2. Move down to file j or search file pattern /
3. Rename R
4. Open the new file name <CR> (enter).

Whether this is shorter to type or not will depend on the number of files in your directory.

This answer on vi.stackexchange suggests using :Move from the tpope/vim-eunuch plugin.

:Move: Rename a buffer and the file on disk simultaneously.
