Dependency Injection in Ruby 07 Oct 04

Introduction

At the 2004 Ruby Conference, Jamis Buck had the unenviable task to explain Dependency Injection to a bunch of Ruby developers. First of all, Dependency Injection (DI) and Inversion of Control (IoC) is hard to explain, the benefits are subtle and the dynamic nature of Ruby make those benefits even more marginal. Furthermore examples using DI/IoC are either too simple (and don’t convey the usefulness) or too complex (and difficult to explain in the space of an article or presentation). I once attempted to explain DI/IoC to a room of Java programmers (see onestepback.org/articles/dependencyinjection/), so I can’t pass up trying to explain it to Ruby developers.

Thanks goes to Jamis Buck (the author of the Copland DI/IoC framework) who took the time to review this article and provide feedback.

What is Dependency Injection?

#!/usr/bin/env ruby -w
## Using ruby's standard OptionParser to get subcommand's in command line arguments
## Note you cannot do: opt.rb help command
## other options are commander, main, GLI, trollop...

# run it as
# ruby opt.rb --help
# ruby opt.rb foo --help
# ruby opt.rb foo -q
# etc

#!/bin/bash

function kill_unicorn() {
  kill $(ps aux | grep "unicorn master" | grep -v "grep" | awk '{print $2}' | tail -1)
}

Imagine you have a long line of FIX message:

"8=FOO.4.2\u00019=73\u000135=XyZ\u000149=BRKR\u000156=INVMGR\u000134=235\u000152=19980604-07:58:28\u0001112=19980604-07:58:28\u000110=235\u0001"

And you need to humanize it in order to be able to read each field like this:

8=FOO.4.2
9=73
35=XyZ
