aspect4r
Aspect Oriented Programming support for Ruby
Feature
-
extract common logic from multiple methods into before, after, around advices
-
before_filter as method filters (work like before_filters in web application)
-
advices can be customized (e.g. to take an optional method name argument)
-
work as a supporting piece for more complex AOP tasks
Usage
class A
include Aspect4r
around :test do |proxy_method, value|
a4r_invoke proxy_method, value
end
before :test do |value|
puts "entering test(#{value})"
end
before :test, :do_something
before_filter :test do |value|
value >= 0
end
after :test do |result, value|
puts "test(#{value}) returned #{result}"
result
end
after :test, :do_something_else
def test value
...
end
def do_something value
...
end
def do_something_else result, value
...
end
end
How does it work?

Note on Patches/Pull Requests
-
Fork the project.
-
Make your feature addition or bug fix.
-
Add tests for it. This is important so I don’t break it in a future version unintentionally.
-
Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
-
Send me a pull request. Bonus points for topic branches.
