module RuboCop::AST::ConditionalNode
Common functionality for nodes that have conditions: `if`, `while`, `until`, `case`. This currently doesn't include `when` nodes, because they have multiple conditions, and need to be checked for that.
Public Instance Methods
Returns the body associated with the condition. This works together with each node's custom destructuring method to select the correct part of the node.
@note For `if` nodes, this is the truthy branch.
@return [Node, nil] the body of the node
# File lib/rubocop/ast/node/mixin/conditional_node.rb, line 40 def body node_parts[1] end
Returns the condition of the node. This works together with each node's custom destructuring method to select the correct part of the node.
@return [Node, nil] the condition of the node
# File lib/rubocop/ast/node/mixin/conditional_node.rb, line 29 def condition node_parts[0] end
Checks whether the condition of the node is written on more than one line.
@return [Boolean] whether the condition is on more than one line
# File lib/rubocop/ast/node/mixin/conditional_node.rb, line 21 def multiline_condition? !single_line_condition? end
Checks whether the condition of the node is written on a single line.
@return [Boolean] whether the condition is on a single line
# File lib/rubocop/ast/node/mixin/conditional_node.rb, line 13 def single_line_condition? loc.keyword.line == condition.source_range.line end
