Returns:
  • (Array) - The resulting static nodes

Parameters:
  • environment (Sass::Environment) -- The lexical environment containing 
def _perform(environment)
  from = @from.perform(environment)
  to = @to.perform(environment)
  from.assert_int!
  to.assert_int!
  to = to.coerce(from.numerator_units, from.denominator_units)
  range = Range.new(from.to_i, to.to_i, @exclusive)
  children = []
  environment = Sass::Environment.new(environment)
  range.each do |i|
    environment.set_local_var(@var, Sass::Script::Number.new(i, from.numerator_units, from.denominator_units))
    children += perform_children(environment)
  end
  children
end

def initialize(var, from, to, exclusive)

Parameters:
  • exclusive (Boolean) -- Whether to include `to` in the loop
  • to (Script::Node) -- The parse tree for the final expression
  • from (Script::Node) -- The parse tree for the initial expression
  • var (String) -- The name of the loop variable 
def initialize(var, from, to, exclusive)
  @var = var
  @from = from
  @to = to
  @exclusive = exclusive
