Overview

This is the parent class of a lot of built-in visitors for Syntax Tree. It reflects visiting each of the fields on every node in turn. It itself does not do anything with these fields, it leaves that behavior up to the subclass to implement.

In order to properly use this class, you will need to subclass it and implement #comments, #field, #list, #node, #pairs, and #text. Those are documented here.

comments(node)

This accepts the node that is being visited and does something depending on the comments attached to the node.

field(name, value)

This accepts the name of the field being visited as a string (like “value”) and the actual value of that field. The value can be a subclass of Node or any other type that can be held within the tree.

list(name, values)

This accepts the name of the field being visited as well as a list of values. This is used, for example, when visiting something like the body of a Statements node.

node(name, node)

This is the parent serialization method for each node. It is called with the node itself, as well as the type of the node as a string. The type is an internally used value that usually resembles the name of the ripper event that generated the node. The method should yield to the given block which then calls through to visit each of the fields on the node.

text(name, value)

This accepts the name of the field being visited as well as a string value representing the value of the field.

pairs(name, values)

This accepts the name of the field being visited as well as a list of pairs that represent the value of the field. It is used only in a couple of circumstances, like when visiting the list of optional parameters defined on a method.
