`class Reference`

An Ruby-specific reference which can be resolved to zero or more definitions.

Definitions

`def self.from_const(node, language)`

Create a reference from a constant node.

Signature

parameter　node　Prism::Node: The constant node.
parameter　language　Language: The language instance.

Implementation

def self.from_const(node, language)
	lexical_path = append_const(node)
	
	return self.new(node.location.slice, language, lexical_path)
end

`def self.append_const(node, path = [])`

Append a constant node to the path.

Signature

parameter　node　Prism::Node: The constant node.
parameter　path　Array: The path to append to.

Implementation

def self.append_const(node, path = [])
	case node.type
	when :constant_read_node
		path << [nil, node.name.to_s]
	when :constant_path_node
		if node.parent
			append_const(node.parent, path)
			path << ["::", node.name.to_s]
		else
			path << [nil, node.name.to_s]
		end
	when :call_node
		# For call nodes like Tuple(...), treat them as constant references
		if node.receiver.nil?
			path << [nil, node.name.to_s]
		else
			append_const(node.receiver, path)
			path << [".", node.name.to_s]
		end
	else
		raise ArgumentError, "Could not determine reference for #{node.type}!"
	end
	
	return path
end

`def split(text)`

Split a Ruby identifier into prefix and name components.

Signature

parameter　text　String: The text to split.

Implementation

def split(text)
	text.scan(/(::|\.|#|:)?([^:.#]+)/)
end
