VisibilityChecker exposes a single method, visibility_changes, for returning an array with places where any ancestor of the given class/module has changed the visibility of any of the methods classes/modules methods.
gem install visibility_checker
Source code is available on GitHub at github.com/jeremyevans/visibility_checker
Here’s an example showing normal use:
require 'visibility_checker' class C def a end end VisibilityChecker.visibility_changes(C) # => [] module M def a end end C.include M VisibilityChecker.visibility_changes(C) # => [] class C private :a end VisibilityChecker.visibility_changes(C) # => [#<struct VisibilityChecker::VisibilityChange # method=:a, defined_in=M, original_visibility=:public, # overridden_by=C, new_visibility=:private>]
You can also extend classes or modules with VisibilityChecker and call visibility_changes on them:
C.extend VisibilityChecker C.visibility_changes # => [#<struct VisibilityChecker::VisibilityChange ... >]
Or if you want to add the visibility_changes method to all classes and modules, have Module include it:
Module.include VisibilityChecker M.visibility_changes # => []
VisibilityChecker.visibility_changes accepts two keyword arguments:
- stop_at
-
The ancestor at which to stop for visibility changes, Object by default.
- skip_owners
-
Skip reporting a visibility change if the method that was overridden was defined in this module/class. Set to Kernel by default as general Ruby practice is that Kernel methods can be overridden (e.g. Enumerable#select).
