Catchy

catchy: Instantly appealing and memorable, a gem to capture chains of method calls.

Gem Version Build Status Code Climate

Installation

Add this line to your application's Gemfile:

gem 'catchy'

And then execute:

$ bundle

Or install it yourself as:

$ gem install catchy

Usage

Basic

At it's simplest you just instantiate a new Catchy and give it to whatever you want to capture the calls of:

proxy = Catchy.new
object.black_box( proxy )

Then you can get the chain of called methods as a string:

proxy.to_s # => "some.chain.of.method.calls"

Configuration

"But what if I need to capture call chains that include calls to to_s?" I hear you saying. Ah, we thought of that. Simply tell Catchy that you want another name for to_s when you create it, like this:

proxy = Catchy.new(to_s: :__to_string__)

or with a config block, handy for a Rails initializer or similar, like this:

# config/initializers/catchy.rb
Catchy.configure do |config|
  config.to_s = :__to_string__
end

# app/whatever/class.rb
proxy = Catchy.new

Then you can use it like this:

proxy.call.whatever.you.want.to_s
...
proxy.__to_string__

Special thanks

To Hüseyin Öztürk for suggesting the name. Originally the gem was called MethodChainProxy, but mr Öztürk found it less than sexy and suggested: "something funny and relevant, catchy ..." so there we where, Catchy. Exellent work!
