class Sass::Script::Operation

such as ‘!a + !b` or `“foo” + 1`.
A SassScript parse node representing a binary operation,

def initialize(operand1, operand2, operator)

Parameters:
  • operator (Symbol) -- The operator to perform.
  • operand2 (Script::Node) -- The parse-tree node
  • operand1 (Script::Node) -- The parse-tree node 
def initialize(operand1, operand2, operator)
  @operand1 = operand1
  @operand2 = operand2
  @operator = operator
end

def inspect

Returns:
  • (String) - A human-readable s-expression representation of the operation 
def inspect
  "(#{@operator.inspect} #{@operand1.inspect} #{@operand2.inspect})"
end

def perform(environment)

Raises:
  • (Sass::SyntaxError) - if the operation is undefined for the operands

Returns:
  • (Literal) - The SassScript object that is the value of the operation

Parameters:
  • environment (Sass::Environment) -- The environment in which to evaluate the SassScript 
def perform(environment)
  literal1 = @operand1.perform(environment)
  literal2 = @operand2.perform(environment)
  begin
    literal1.send(@operator, literal2)
  rescue NoMethodError => e
    raise e unless e.name.to_s == @operator.to_s
    raise Sass::SyntaxError.new("Undefined operation: \"#{literal1} #{@operator} #{literal2}\".")
  end
