def body_nodes(type, ignoring = [])
  children[1..].compact.flat_map do |child|
    if ignoring.include? child.type
      []
    else
      child.each_node(type, ignoring | type).to_a

#condition ⇒ Reek::AST::Node

Returns the condition that is associated with a conditional node. For instance, this code

if charlie(bravo) then delta end

would be parsed into this AST:

s(:if,
  s(:send, nil, :charlie,
    s(:lvar, :bravo)),
  s(:send, nil, :delta), nil)

so in this case we would return this

s(:send, nil, :charlie,
  s(:lvar, :bravo))

as condition.

Returns:

  • (Reek::AST::Node) —

    the condition that is associated with a conditional node. For instance, this code

    if charlie(bravo) then delta end

    would be parsed into this AST:

    s(:if,
  s(:send, nil, :charlie,
    s(:lvar, :bravo)),
  s(:send, nil, :delta), nil)

    so in this case we would return this

    s(:send, nil, :charlie,
  s(:lvar, :bravo))

    as condition.
