class RuboCop::AST::PairNode
A node extension for `pair` nodes. This will be used in place of a plain node when the builder constructs the AST, making its methods available to all `pair` nodes within RuboCop.
Constants
- COLON
- HASH_ROCKET
- SPACED_COLON
- SPACED_HASH_ROCKET
Public Instance Methods
Checks whether the `pair` uses a colon delimiter.
@return [Boolean] whether this `pair` uses a colon delimiter
# File lib/rubocop/ast/node/pair_node.rb, line 25 def colon? loc.operator.is?(COLON) end
Returns the delimiter of the `pair` as a string. Returns `=>` for a colon delimited `pair`, and `:` for a hash rocket delimited `pair`.
@param [Boolean] with_spacing whether to include spacing @return [String] the delimiter of the `pair`
# File lib/rubocop/ast/node/pair_node.rb, line 34 def delimiter(with_spacing = false) if with_spacing hash_rocket? ? SPACED_HASH_ROCKET : SPACED_COLON else hash_rocket? ? HASH_ROCKET : COLON end end
Checks whether the `pair` uses a hash rocket delimiter.
@return [Boolean] whether this `pair` uses a hash rocket delimiter
# File lib/rubocop/ast/node/pair_node.rb, line 18 def hash_rocket? loc.operator.is?(HASH_ROCKET) end
Returns the inverse delimiter of the `pair` as a string.
@param [Boolean] with_spacing whether to include spacing @return [String] the inverse delimiter of the `pair`
# File lib/rubocop/ast/node/pair_node.rb, line 46 def inverse_delimiter(with_spacing = false) if with_spacing hash_rocket? ? SPACED_COLON : SPACED_HASH_ROCKET else hash_rocket? ? COLON : HASH_ROCKET end end
Custom destructuring method. This is used to normalize the branches for `pair` and `kwsplat` nodes, to add duck typing to `hash` elements.
@return [Array<Node>] the different parts of the `pair`
# File lib/rubocop/ast/node/pair_node.rb, line 58 def node_parts to_a end
