Overview

A node extension for irange and erange nodes. This will be used in place of a plain node when the builder constructs the AST, making its methods available to all irange and erange nodes within RuboCop.

Class Method Summary

Node - Inherited

.new,
.def_recursive_literal_predicate

Define a recursive_? predicate method for the given node kind.

NodePattern::Macros - Extended

def_node_matcher

Define a method which applies a pattern to an AST node.
def_node_search

Define a method which recurses over the descendants of an AST node, checking whether any of them match the provided pattern.

#loop_keyword?
Note
loop { } is a normal method call and thus not a loop keyword.
#multiline?

Predicates.
#mutable_literal?, #numeric_type?, #operator_keyword?,
#parent

Returns the parent node, or nil if the receiver is a root node.
#parent?, #parenthesized_call?, #post_condition_loop?,
#pure?

Some expressions are evaluated for their value, some for their side effects, and some for both.
#range_type?, #reference?, #root?,
#send_type?

Most nodes are of 'send' type, so this method is defined separately to make this check as fast as possible.
#shorthand_asgn?, #single_line?, #special_keyword?, #truthy_literal?,
#value_used?

Some expressions are evaluated for their value, some for their side effects, and some for both If we know that an expression is useful only for its side effects, that means we can transform it in ways which preserve the side effects, but change the return value So, does the return value of this node matter? If we changed it to (…​; nil), might that affect anything?

Node - Inherited

#ancestors

Returns an array of ancestor nodes.
#assignment_or_similar?

Some cops treat the shovel operator as a kind of assignment.
#class_constructor?, #class_definition?, #complete!, #const_name, #defined_module, #defined_module_name,
#each_ancestor

Calls the given block for each ancestor node from parent to root.
#first_line, #global_const?, #lambda?, #lambda_or_proc?, #last_line,
#left_sibling

Use is discouraged, this is a potentially slow method and can lead to even slower algorithms.
#left_siblings

Use is discouraged, this is a potentially slow method and can lead to even slower algorithms.
#line_count,
#loc?

Shortcut to safely check if a location is present.
#loc_is?

Shortcut to safely test a particular location, even if this location does not exist or is nil.
#match_guard_clause?, #module_definition?,
#node_parts

Common destructuring method.
#nonempty_line_count,
#parent_module_name

Searching the AST.
#proc?, #receiver, #recursive_basic_literal?, #recursive_literal?,
#right_sibling

Use is discouraged, this is a potentially slow method and can lead to even slower algorithms.
#right_siblings

Use is discouraged, this is a potentially slow method and can lead to even slower algorithms.
#sibling_index

Returns the index of the receiver node in its siblings.
#source
Note
 Some rare nodes may have no source, like s(:args) in foo {}.
#source_length, #source_range, #str_content, #struct_constructor?,
#type?

Determine if the node is one of several node types in a single query Allows specific single node types, as well as "grouped" types (e.g.
#updated

Override Node#updated so that AST::Processor does not try to mutate our ASTs.
#defined_module0, #new_class_or_module_block?, #parent_module_name_for_block, #parent_module_name_for_sclass, #parent_module_name_part, #visit_ancestors

Descendence - Included

#child_nodes

Returns an array of child nodes.
#descendants

Returns an array of descendant nodes.
#each_child_node

Calls the given block for each child node.
#each_descendant

Calls the given block for each descendant node with depth first order.
#each_node

Calls the given block for the receiver and each descendant node in depth-first order.

Sexp - Included

#s

Creates a Node with type type and children children.
