class Prism::InterpolatedMatchLastLineNode - prism: Ruby Standard Library Documentation

# class Prism::InterpolatedMatchLastLineNode

Represents a regular expression literal that contains interpolation that is being used in the predicate of a conditional to implicitly match against the last line read by an IO object.

### Public Class Methods

new(source, node_id, location, flags, opening_loc, parts, closing_loc) click to toggle source

Initialize a new `InterpolatedMatchLastLineNode` node.

    # File prism/node.rb, line 10482
    def initialize(source, node_id, location, flags, opening_loc, parts, closing_loc)
      @source = source
      @node_id = node_id
      @location = location
      @flags = flags
      @opening_loc = opening_loc
      @parts = parts
      @closing_loc = closing_loc
    end

type() click to toggle source

Return a symbol representation of this node type. See ‘Node::type`.

### Public Instance Methods

===(other) click to toggle source

Implements case-equality for the node. This is effectively == but without comparing the value of locations. Locations are checked only for presence.

    # File prism/node.rb, line 10636
    def ===(other)
      other.is_a?(InterpolatedMatchLastLineNode) &&
        (flags === other.flags) &&
        (opening_loc.nil? == other.opening_loc.nil?) &&
        (parts.length == other.parts.length) &&
        parts.zip(other.parts).all? { |left, right| left === right } &&
        (closing_loc.nil? == other.closing_loc.nil?)
