How do I split string such as:
aaaaa
bbbb
aaaaa
ccccccc
aaa
rrrrt
into an array using blank lines as delimiter?

Even though you have selected an answer you should edit your question to address @Tiw's question. The answer is not just for your benefit, so the question needs to be clear to all current and future readers.Cary Swoveland– Cary Swoveland2019-01-28 17:42:35 +00:00Commented Jan 28, 2019 at 17:42

Well, with String#split
'aaaaa bbbb'.split
=> ["aaaaa", "bbbb"]
split(pattern=nil, [limit]) → an_arrayDivides str into substrings based on a delimiter, returning an array of these substrings.
[...]
If
patternisnil, the value of$; is used. If$; isnil(which is the default),stris split on whitespace as if' 'were specified.
UPDATE:
To split on empty line, you can use /\n{2,}/ pattern. It also handles paragraphs separated with more than one empty line:
a = <<END
aaaaa
bbbb
aaaaa
ccccccc
aaa
rrrrt
END
a.split(/\n{2,}/)
=> ["aaaaa\nbbbb", "aaaaa\nccccccc", "aaa\nrrrrt\n"]

multiline, though? And they want to split by paragraphs, not by lines even.

ah, with corrected formatting, it's a different question

If you replace 'bbbb' with 'bbbb\n' (edge condition) in above your example, how code will deal with it?

You could also split by
/^\n+/ which preserves the trailing newlines on the non-empty lines.
