settings - How to stop VIM from adding a newline at end of file?

Question

So I work in a PHP shop, and we all use different editors, and we all have to work on Windows. I use vim, and everyone in the shop keeps complaining that whenever I edit a file there is a newline at the bottom. I've searched around and found that this is a documented behavior of vi & vim... but I was wondering if there was some way to disable this feature. (It would be best if I could disable it for specific file extensions).

If anyone knows about this, that would be great!

Answer 1

And for vim 7.4+ you can use (preferably on your .vimrc) (thanks to 罗泽轩 for that last bit of news!):

:set nofixendofline

Now regarding older versions of vim.

Even if the file was already saved with new lines at the end:

vim -b file and once in vim:

:set noeol
:wq

done.

alternatively you can open files in vim with :e ++bin file

Yet another alternative:

:set binary
:set noeol
:wq
