This tree is _immutable_: once a document has been parsed, those Ruby objects can't be changed. Modifications are performed by _copying_ existing nodes, applying changes to the copy, then making a new tree to hold the copied node. Where possible, unmodified nodes are retained in the new tree (it's _persistent_). + +The copy-and-modify workflow is supported by a few methods on the AST nodes: + +- `.merge(new_attrs)` returns a copy of the node with `new_attrs` applied. This new copy can replace the original node. +- `.add_{child}(new_child_attrs)` makes a new node with `new_child_attrs`, adds it to the array specified by `{child}`, and returns a copy whose `{children}` array contains the newly created node. + +For example, to rename a field and add an argument to it, you could: + +```ruby +modified_node = field_node + # Apply a new name + .merge(name: "newName") + # Add an argument to this field's arguments + .add_argument(name: "newArgument", value: "newValue") +``` + +Above, `field_node` is unmodified, but `modified_node` reflects the new name and new argument. + +## Analyze/Modify + +To inspect or modify a parsed document, extend {{ "GraphQL::Language::Visitor" | api_doc }} and implement its various hooks. It's an implementation of the [visitor pattern](https://en.wikipedia.org/wiki/Visitor_pattern). In short, each node of the tree will be "visited" by calling a method, and those methods can gather information and perform modifications. + +In the visitor, each node class has a hook, for example: + +- {{ "GraphQL::Language::Nodes::Field" | api_doc }}s are routed to `#on_field` +- {{ "GraphQL::Language::Nodes::Argument" | api_doc }}s are routed to `#on_argument` + +See the {{ "GraphQL::Language::Visitor" | api_doc }} API docs for a full list of methods. + +Each method is called with `(node, parent)`, where: + +- `node` is the AST node currently visited +- `parent` is the AST node above this node in the tree + +The method has a few options for analyzing or modifying the AST: + +#### Continue/Halt + +To continue visiting, the hook should call `super`. This allows the visit to continue to `node`'s children in the tree, for example: + +```ruby +def on_field(_node, _parent) + # Do nothing, this is the default behavior: + super +end +``` + +To _halt_ the visit, a method may skip the call to `super`. For example, if the visitor encountered an error, it might want to return early instead of continuing to visit. + +#### Modify a Node + +Visitor hooks are expected to return the `(node, parent)` they are called with. If they return a different node, then that node will replace the original `node`. When you call `super(node, parent)`, the `node` is returned. So, to modify a node and continue visiting: + +- Make a modified copy of `node` +- Pass the modified copy to `super(new_node, parent)` + +For example, to rename an argument: + +```ruby +def on_argument(node, parent) + # make a copy of `node` with a new name + modified_node = node.merge(name: "renamed") + # continue visiting with the modified node and parent + super(modified_node, parent) +end +``` + +#### Delete a Node + +To delete the currently-visited `node`, don't pass `node` to `super(...)`. Instead, pass a magic constant, `DELETE_NODE`, in place of `node`. + +For example, to delete a directive: + +```ruby +def on_directive(node, parent) + # Don't pass `node` to `super`, + # instead, pass `DELETE_NODE` + super(DELETE_NODE, parent) +end +``` + +#### Insert a Node + +Inserting nodes is similar to modifying nodes. To insert a new child into `node`, call one of its `.add_` helpers. This returns a copied node with a new child added. For example, to add a selection to a field's selection set: + +```ruby +def on_field(node, parent) + node_with_selection = node.add_selection(name: "emailAddress") + super(node_with_selection, parent) +end +``` + +This will add `emailAddress` the fields selection on `node`. + + +(These `.add_*` helpers are wrappers around {{ "GraphQL::Language::Nodes::AbstractNode#merge" | api_doc }}.) + +## Print + +The easiest way to turn an AST back into a string of GraphQL is {{ "GraphQL::Language::Nodes::AbstractNode#to_query_string" | api_doc }}, for example: + +```ruby +parsed_doc.to_query_string +# => '{ user(id: "1") { userName } }' +``` + +You can also create a subclass of {{ "GraphQL::Language::Printer" | api_doc }} to customize how nodes are printed.

This removes a complicated concept from GraphQL-Ruby (`irep_node`s) and simplifies the query lifecycle. The main difference relates to how fragment spreads are resolved. In the previous runtime, the possible combinations of fields for a given object were calculated ahead of time, then some of those combinations were used during runtime, but many of them may not have been. In the new runtime, no precalculation is made; instead each object is checked against each fragment at runtime. Instead of creating a `GraphQL::Query::Context::FieldResolutionContext` for _every_ field in the response, the interpreter uses long-lived, mutable objects for execution bookkeeping. This is more complicated to manage, since the changes to those objects can be hard to predict, but it's worth it for the performance gain. When needed, those bookkeeping objects can be "forked", so that two parts of an operation can be resolved independently.
