#arguments ⇒ Array<Rucoa::Nodes::Base>

Examples:

returns arguments

node = Rucoa::Source.new(
  content: <<~RUBY,
    foo(bar, baz)
  RUBY
  uri: 'file:///path/to/example.rb'
).root_node
expect(node.arguments.map(&:name)).to eq(
  %w[
    bar
    baz
  ]
)

Returns:

def arguments
  children[2..]
end

#block ⇒ Rucoa::Nodes::BlockNode?

Examples:

returns nil for method call without block

node = Rucoa::Source.new(
  content: <<~RUBY,
    foo
  RUBY
  uri: 'file:///path/to/example.rb'
).node_at(
  Rucoa::Position.new(
    column: 0,
    line: 1
  )
)
expect(node.block).to be_nil

returns block

node = Rucoa::Source.new(
  content: <<~RUBY,
    foo do
      bar
    end
  RUBY
  uri: 'file:///path/to/example.rb'
).node_at(
  Rucoa::Position.new(
    column: 0,
    line: 1
  )
)
expect(node.block).to be_a(Rucoa::Nodes::BlockNode)

Returns:
