Tip: #1001 - Save buffer without changing Last Modified attribute

There are times when I change something in a file and I've no need for the file's "last modified" time to be changed.
This is often because I'm simply changing a comment in a source file and I don't need my build system to re-compile the file.
If your build of vim has +python you can define the following function and call it instead of using the write command
function! WritePreserveMtime()
python << EEOOFF
import vim
import os.path
import os
fpath = vim.current.buffer.name
atime = os.path.getatime(fpath)
mtime = os.path.getmtime(fpath)
vim.command("w")
os.utime(fpath, (atime, mtime))
EEOOFF
endfunction
See :help python for more help on calling Python from inside vim.
Since I
- map <F3> :w<CR><C-G>
I also
- map <S-F3> :call WritePreserveMtime()<CR><C-G>
