Module: SimpleCov::Formatter::AIFormatter::ASTResolver::MetaclassResolver

Extended by:
T::Sig
Defined in:
lib/simplecov-ai/ast_resolver/metaclass_resolver.rb

Overview

Recognizes constant assignments whose value is a Struct.new / Class.new / Module.new / Data.define block. These bind an anonymous class or module to the constant, so methods defined inside the block belong to that constant rather than to the enclosing lexical scope.

BUILDERS =

Recognized builders mapped to the constructor method that signals the pattern.

T.let({ 'Struct' => :new, 'Class' => :new, 'Module' => :new, 'Data' => :define }.freeze,
T::Hash[String, Symbol])
BLOCK_TYPES =

Every AST node type that attaches a block to a call: do … end / { … } blocks, numbered-parameter blocks ({ _1 }) and Ruby 3.4 it blocks.

T.let(i[block numblock itblock].freeze, T::Array[Symbol])
