class Sass::Script::Interpolation

@see StringInterpolation
A SassScript object representing ‘#{}` interpolation outside a string.

def _perform(environment)

Returns:
  • (Sass::Script::String) - The SassScript string that is the value of the interpolation

Parameters:
  • environment (Sass::Environment) -- The environment in which to evaluate the SassScript 
def _perform(environment)
  res = ""
  res << @before.perform(environment).to_s if @before
  res << " " if @before && @whitespace_before
  val = @mid.perform(environment)
  res << (val.is_a?(Sass::Script::String) ? val.value : val.to_s)
  res << " " if @after && @whitespace_after
  res << @after.perform(environment).to_s if @after
  opts(Sass::Script::String.new(res))
end

def initialize(before, mid, after, wb, wa, originally_text = false)

Parameters:
  • originally_text (Boolean) --
  • wa (Boolean) -- Whether there was whitespace between `}` and `after`
  • wb (Boolean) -- Whether there was whitespace between `before` and `#{`
  • after (Node) -- The SassScript after the interpolation
  • mid (Node) -- The SassScript within the interpolation
  • before (Node) -- The SassScript before the interpolation

end

def inspect

Returns:
  • (String) - A human-readable s-expression representation of the interpolation 
def inspect
  "(interpolation #{@before.inspect} #{@mid.inspect} #{@after.inspect})"
