Module: Sinatra::Delegator

Defined in:
lib/sinatra_opal_patches.rb

Overview

  1. Delegator.delegate (upstream base.rb:2113)

Upstream first probes ‘return super(*args, &block) if respond_to? method_name`. Opal’s ‘super` inside `define_method` is hard-wired to the enclosing Ruby method name (’delegate’) at compile time instead of resolving to the dynamically defined method, which breaks top-level ‘get ’/‘ do … end` on the main object. Skip the super probe; the delegator is the sole hook for main, so Delegator.target.send(…) is always the right dispatch.
