a plain node when the builder constructs the AST, making its methods
A node extension for `case_match` nodes. This will be used in place of

def branches

Returns:
  • (Array) - an array of the bodies of the `in` branches 
def branches
  bodies = in_pattern_branches.map(&:body)
  if else?
    # `empty-else` node sets nil because it has no body.
    else_branch.empty_else_type? ? bodies.push(nil) : bodies.push(else_branch)
  end
  bodies
end

def each_in_pattern(&block)

Deprecated:
  • Use `in_pattern_branches.each`
def each_in_pattern(&block)
  return in_pattern_branches.to_enum(__method__) unless block
  in_pattern_branches.each(&block)
  self
end

def else?

Returns:
  • (Boolean) - whether the `case` statement has an `else` branch 
def else?
  !loc.else.nil?
end

def else_branch

Returns:
  • (nil) - if the case statement does not have an else branch.
  • (EmptyElse) - the empty else branch node of the `case` statement
  • (Node) - the else branch node of the `case` statement 
def else_branch
  node_parts[-1]
end

def in_pattern_branches

Returns:
  • (Array) - an array of `in_pattern` nodes 
def in_pattern_branches
  node_parts[1...-1]
end
