Common functionality for safe assignment. By safe assignment we mean putting parentheses around an assignment to indicate "I know I'm using an assignment as a condition. It's not a mistake."
# File lib/rubocop/cop/mixin/safe_assignment.rb, line 8 def safe_assignment?(node) return false unless node.type == :begin return false unless node.children.size == 1 child = node.children.first case child.type when *Util::EQUALS_ASGN_NODES true when :send _receiver, method_name, _args = *child method_name.to_s.end_with?('=') else false end end
