How can I preserve / maintain consecutive newlines in Ruby here-document?

Question

I wonder how can I preserve consecutive newline characters with Ruby here-document? In my program all of them are collapsed to one newline. For example:

s=<<END
1
2

3


4



END

evaluates to:

s="1\n2\n3\n4\n"

However I would like to preserve the consecutive newlines when for example formatting a BBcode document a letter or something similar.

I don't see this behavior in irb for Ruby 1.9.3p392. How are you running this code, and in what version of Ruby? — Hew Wolff, Aug 09 '13 at 23:42

That looks like a bug to me. Have you tried a multiline %q?

s=%q(1
2

3


4



)
