A SassScript object representing `#{}` interpolation outside a string.
@see StringInterpolation
Interpolation in a property is of the form `before #{mid} after`.
@param before [Node] The SassScript before the interpolation @param mid [Node] The SassScript within the interpolation @param after [Node] The SassScript after the interpolation @param wb [Boolean] Whether there was whitespace between `before` and `#{` @param wa [Boolean] Whether there was whitespace between `}` and `after` @param originally_text [Boolean]
Whether the original format of the interpolation was plain text, not an interpolation. This is used when converting back to SassScript.
# File lib/sass/script/interpolation.rb, line 17 17: def initialize(before, mid, after, wb, wa, originally_text = false) 18: @before = before 19: @mid = mid 20: @after = after 21: @whitespace_before = wb 22: @whitespace_after = wa 23: @originally_text = originally_text 24: end
Returns the three components of the interpolation, `before`, `mid`, and `after`.

Evaluates the interpolation.
