Module: SimpleCov::Formatter::AIFormatter::ASTResolver::DynamicMethodResolver

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

Overview

Recognizes define_method(:name) do … end and define_singleton_method(:name) { … } blocks whose method name is a literal symbol or string. Such a block is the body of the method it defines, so deficits inside it belong to that method rather than to the whole enclosing class. Dynamic names (define_method(name)), explicit foreign receivers (klass.define_method) and block-less forms (define_method(:a, method(:b))) are not recognized and stay transparent.

DEFINERS =

T::Hash[Symbol, T::Boolean])
LITERAL_NAME_TYPES =

Node types accepted as a literal method name.
