Why does rufo replace the \n string escape with actual newline? Can we not?

[Nitrodist]

I have code that is like this:

def abc
  print "Hello\nWorld"
end

After formatting with Rufo, it changes the code to this:

  print "Hello
World"

Often I have additional code in a string I'm interpolating - for example "#{a}\n#{b}\n#{c}\n". I can understand this usecase, sure. But, simple calls like.join("\n") result in a needless newline.

It's much more readable if I was able to write .join("\n") IMO!

Actually, this appears to be a rufo-vim issue 😢 ruby-formatter/rufo-vim#28

Does it reproduce using rufo standalone, or only with rufo-vim?
When run standalone, it worked correctly on my environment.

$ rufo --version
rufo 0.16.1
$ rufo <<EOF
def abc
  print "Hello\nWorld"
end
EOF
def abc
  print "Hello\nWorld"
end

This is not a rufo's issue but rufo-vim's one ( And it has already opened as ruby-formatter/rufo-vim#28 ). So close this issue.
