Regex: add a new line for each sentence using vim

I was wondering how to turn a paragraph into bullet sentences in vim.

before:

sentence1. sentence2.  sentence3.  sentence4.  sentence5.  sentence6. 
sentence7.

after

SENTENCE 1.

SENTENCE2.

sentence3

sentence4.

sentence5.

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

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

I used two carriage returns according to the output format you indicated in the question. There are several alternative forms of regular expressions that you can 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 possibly many others.

A non-regexp way to do this:

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

:help change.txt
:help \@<=
:help :substitute
:help getline()
:help append()

Perl:

perl -e "$_ = <>; s/\.\s*/.\n/g; print"

, :

my $input = 'foo. bar. baz.';
$input =~ s/
    \.      # A literal '.'
    \s*     # Followed by 0 or more space characters
    /.\n/gx;       # g for all occurences, x to allow comments and whitespace in regex
print $input;

Python:

import re
input = 'foo. bar. baz.'
print re.sub(r'\.\s*', '.\n', input)
