[ruby-dev:49980] [Ruby trunk Bug#13204][Closed] Search order of constant is different
From:
nobu@...
Date:
2017-02-10 04:31:03 UTC
List:
ruby-dev #49980
Issue #13204 has been updated by Nobuyoshi Nakada.
Status changed from Open to Closed
Intentional.
Top level constants are constants defined in `Object`, but `BasicObject` does not inherit `Object`.
----------------------------------------
Bug #13204: Search order of constant is different
https://bugs.ruby-lang.org/issues/13204#change-62942
* Author: okkez _
* Status: Closed
* Priority: Normal
* Assignee:
* Target version:
* ruby -v:
* Backport: 2.2: UNKNOWN, 2.3: UNKNOWN, 2.4: UNKNOWN
----------------------------------------
```ruby
class CleanRoom < BasicObject
def call
instance_eval(<<-CODE)
$stdout.puts ::ENV.size
CODE
end
def call2
instance_eval(<<-CODE)
$stdout.puts ENV.size
CODE
end
def call3
instance_eval { $stdout.puts ::ENV.size }
end
end
class CleanRoom2
def call
instance_eval(<<-CODE)
$stdout.puts ENV.size
CODE
end
end
CleanRoom.new.call # => 80 (in my environment)
CleanRoom2.new.call # => 80
CleanRoom.new.call3 # => 80
CleanRoom.new.call2 # => t.rb:14:in `instance_eval': uninitialized constant #<Class:#<CleanRoom:0x0055698d201da8>>::ENV (NameError)
```
`CleanRoom` instance cannot refer constants defined in top level.
Is this intentional?
