AroundMethod

AroundMethod is a Ruby gem for method composition. This gem was inspired by ActionController filters, but brings the same pattern to any Ruby class. :cool:

Installation

Add this line to your application's Gemfile:

gem 'around_method'

And then execute:

$ bundle

Or install it yourself as:

$ gem install around_method

Usage

AroundMethod is automatically available on all classes.

Currently, AroundMethod only supports wrapping around methods. Before and after composition is planned for the future.

Around

class Class
    around_method :wrapped, :wrapper

    def wrapped
      'cognito'
    end

    def wrapper
      yield + ' ergo sum'
    end
end

Calling wrapped returns: cognito ergo sum

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
