How to get nodes which represent autoload statement？

[Super-Xray]

I'm working on using prism to derive statements like autoload :Bar, "bar" but I couldn't find which kind of Node contains this kind of statements. I had tried to search nodes definition which contains autoload in the document and source codes and didn't find valid result.

Hi @Super-Xray — those are all CallNode nodes, because autoload isn't a keyword. To find them all, a visitor would be a good idea, as in:

class AutoloadVisitor < Prism::Visitor
  attr_reader :autoloads

  def initialize(autoloads)
    @autoloads = autoloads
  end

  def visit_call_node(node)
    autoloads << node if node.name == :autoload
    super
  end
end

source = <<~RUBY
module Foo
  autoload :Bar1, "bar.rb",
  autoload :Bar2, "bar.rb"
  autoload :Bar3, "bar.rb"
end
RUBY

autoloads = []
Prism.parse(source).value.accept(AutoloadVisitor.new(autoloads))

p autoloads # [#<Prism::CallNode>, #<Prism::CallNode>, #<Prism::CallNode>]

you may want to additionally restrict it by checking if node.receiver.nil? and anything else.
