Answer 1

Since all the other answers so far show how to do it various programming languages and you have tagged the question with Vim, here's how to do it in Vim:

:%s/\.\(\s\+\|$\)/.\r\r/g

I've used two carriage returns to match the output format you showed in the question. There are a number of alternative regular expression forms you could use:

" Using a look-behind
:%s/\.\@<=\( \|$\)/\r\r/g
" Using 'very magic' to reduce the number of backslashes
:%s/\v\.( |$)/.\r\r/g
" Slightly different formation: this will also break if there
" are no spaces after the full-stop (period).
:%s/\.\s*$\?/.\r\r/g

and probably many others.

A non-regexp way of doing it would be:

:let s = getline('.')
:let lineparts = split(s, '\.\@<=\s*')
:call append('.', lineparts)
:delete
