class SyntaxTree::LParen - RDoc Documentation

1. SyntaxTree::
2. LParen

LParen represents the use of a left parenthesis, i.e., (.

String

the left parenthesis

def self.default
  new(value: "(", location: Location.default)
end

Because some nodes keep around a ( token so that comments can be attached to it if they occur in the source, oftentimes an LParen is a child of another node. This means it’s required at initialization time. To make it easier to create LParen nodes without any specific value, this method provides a default node.

def initialize(value:, location:)
  @value = value
  @location = location
  @comments = []
end

def ===(other)
  other.is_a?(LParen) && value === other.value
end

def accept(visitor)
  visitor.visit_lparen(self)
end

def copy(value: nil, location: nil)
  node =
    LParen.new(
      value: value || self.value,
      location: location || self.location
    )

  node.comments.concat(comments.map(&:copy))
  node
end

def deconstruct_keys(_keys)
  { value: value, location: location, comments: comments }
end

def format(q)
  q.text(value)
end
