Ruby: escape escape sequence?

Question

There is a string:

str = "foo\nbar"

How can I escape it to:

'foo\nbar'

?

I noticed "#{str}" doesn't work.

Answer 1

Add another \:

"foo\\nbar" == 'foo\nbar'  #=> true

Single-quoted strings do not have interpolation, so #{str} does nothing special in them.

Answer 2

str.inspect Should do it for you
