Constructor Details

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

Interpolation in a property is of the form before #{mid} after.

Parameters:

  • (Node) before — The SassScript before the interpolation
  • (Node) mid — The SassScript within the interpolation
  • (Node) after — The SassScript after the interpolation
  • (Boolean) wb — Whether there was whitespace between before and #{
  • (Boolean) wa — Whether there was whitespace between } and after
  • (Boolean) originally_text (defaults to: false) — Whether the original format of the interpolation was plain text, not an interpolation. This is used when converting back to SassScript.
