8. Implementation
9. Issues Needs a lot of Type Needs accuracy Needs expandability Needs flexibility
10. TracePoint TracePoint.new(:call) do |tp| args = tp.parameters.to_h do |op, name| b = tp.binding [name, b.local_variable_get(name).dup] end p [tp.self, args] end.enable(target: target) do require '...' end
11. Needs a New 
 Model Load Before After Feature
12. Rack Architecture
13. use Middleware1 use Middleware2 use Middleware3 run App.new Rack Architecture
14. use Middleware1 use Middleware2 use Middleware3 run -> { require 'library' } Use case for Library
15. require 'library' use Middleware1 use Middleware2 use Middleware3 run -> { Rails.application.eager_load! } Use case for Application

20. Rack Orthoses class Middleware def initialize(app) @app = app end def call(env) @app.call(env) end end class Middleware def initialize(loader) @loader = loader end def call @loader.call end end
21. Store store = @loader.call pp store #=> { "Foo" => #<Content>, "Bar::Baz" => #<Content> }
22. Content store = @loader.call store["Foo"] << "def foo: () -> int" store["Foo"] << "alias bar foo" store["Foo"] << "include Baz"
23. CallTracer foo = CallTracer.new store = foo.trace(Foo.method(:foo)) do @loader.call end foo.captures.each do |capture| capture.method.receiver capture.argument[:name] end
24. CallTracer::Lazy foo = CallTracer::Lazy.new store = foo.trace('Foo#foo')) do @loader.call end foo.captures.each do |capture| capture.method.receiver capture.argument[:name] end
25. Builder example Orthoses::Builder.new do use Orthoses::CreateFileByName use Orthoses::Mid, option: true use Orthoses::Tap do |store| store["Foo"] << "def foo: () -> void" end use Orthoses::Mixin run -> { require '...' } end
26. Middleware Example module Orthoses class Mid def initialize(loader, option: false) @loader = loader @option = option end def call foo = Orthoses::CallTracer::Lazy.new store = foo.trace('Foo#foo') do @loader.call end foo.captures.each do |capture| mod = capture.method.receiver name = Utils.module_name(mod) or next store[name] << "def bar: () -> void" end store end
