# ruby-method-wrapper

Allow intercept method invocations. Useful for log, cache, etc...

## Usage

Step 1: Include in your Gemfile.

```ruby

gem 'ruby_method_wrapper'

```

Step 2: Write an example.

```ruby

require 'bundler/setup'

require 'method_wrapper'

class Bob

  def say_hello

    puts "Hello!"

  end

end

Bob.wrap_instance_method(pattern: /^say_hello$/, & ->(method, *args, &block) do

  puts "Before call #{method.name}"

  method.call(*args, &block)

  puts "After call #{method.name}"

end)

Bob.new.say_hello

```

Also is possible:

* Invoke private and protected methods.

* Invoke class methods.

* Replace method call with another implementation.
