Smithy

Smith is an Inversion of Control (IoC) container for Ruby. It's based on an example given in Jim Weirich's Dependency Injection: Vitally Important or Totally Irrelevant talk at O'REILLY OSCON 2005. He called the example matzdi_constructor so, presumably, Matz was involved as well.

Installation

Add this line to your application's Gemfile:

gem 'smithy'

And then execute:

$ bundle

Or install it yourself as:

$ gem install smithy

Usage

require "rubygems"
require "bundler/setup"

require "logger"
require "smithy"

class LoggingErrorReporter
  def initialize(logger)
    @logger = logger
  end

  def report(error)
    @logger.error("badness: #{error}")
  end
end

container = Smithy::Container.new
container.register(:logger, Logger.new($stdout)) # you can register literal objects
container.register(:error_reporter, LoggingErrorReporter, :logger) # you can also register classes

container.instance(:error_reporter).report("no more coffee")
