'State' Design Pattern from the Gang of Four book. Many other state machines focus on events and transitions. This state machine focuses on behavior and reducing conditional logic.
Argser (from 'ARGuments parSER') is a library that aims to simplify the process of parsing arguments in command line scripts written in Ruby. It provides an easy way to specify which parameters are valid, their type or format, error conditions, description, etc. In that way, it reduces the need to write code specificaly to parse and validate such arguments. The idea is pretty simple. To be able to use the arguments passed when the script was executed in a easy and consistent way, you only need to specify some general options for the application, a list of parameters and some properties that must hold for both, parameters and what is called the 'remaining array' (an array with strings that don't belong to any parameter).
Have you ever wanted to call <code>exit()</code> with an error condition, but weren't sure what exit status to use? No? Maybe it's just me, then. Anyway, I was reading manpages late one evening before retiring to bed in my palatial estate in rural Oregon, and I stumbled across <code>sysexits(3)</code>. Much to my chagrin, I couldn't find a +sysexits+ for Ruby! Well, for the other 2 people that actually care about <code>style(9)</code> as it applies to Ruby code, now there is one! Sysexits is a *completely* *awesome* collection of human-readable constants for the standard (BSDish) exit codes, used as arguments to +exit+ to indicate a specific error condition to the parent process. It's so fantastically fabulous that you'll want to fork it right away to avoid being thought of as that guy that's still using Webrick for his blog. I mean, <code>exit(1)</code> is so passé! This is like the 14-point font of Systems Programming. Like the C header file from which this was derived (I mean forked, naturally), error numbers begin at <code>Sysexits::EX__BASE</code> (which is way more cool than plain old +64+) to reduce the possibility of clashing with other exit statuses that other programs may already return. The codes are available in two forms: as constants which can be imported into your own namespace via <code>include Sysexits</code>, or as <code>Sysexits::STATUS_CODES</code>, a Hash keyed by Symbols derived from the constant names. Allow me to demonstrate. First, the old way: exit( 69 ) Whaaa...? Is that a euphemism? What's going on? See how unattractive and... well, 1970 that is? We're not changing vaccuum tubes here, people, we're <em>building a totally-awesome future in the Cloud™!</em> include Sysexits exit EX_UNAVAILABLE Okay, at least this is readable to people who have used <code>fork()</code> more than twice, but you could do so much better! include Sysexits exit :unavailable Holy Toledo! It's like we're writing Ruby, but our own made-up dialect in which variable++ is possible! Well, okay, it's not quite that cool. But it does look more Rubyish. And no monkeys were patched in the filming of this episode! All the simpletons still exiting with icky _numbers_ can still continue blithely along, none the wiser.
= DESCRIPTION: Provides a Chef handler which can report run status, including any changes that were made, to a rabbit server. In the case of failed runs a backtrace will be included in the details reported. Based on the Graylog Gelf handler by Jon Wood (<jon@blankpad.net>) https://github.com/jellybob/chef-gelf = REQUIREMENTS: * A Rabbit server running somewhere. = USAGE: This example makes of the chef_handler cookbook, place some thing like this in cookbooks/chef_handler/recipes/rabbit.rb and add it to your run list. include_recipe "chef_handler::default" gem_package "chef-rabbit" do action :nothing end.run_action(:install) # Make sure the newly installed Gem is loaded. Gem.clear_paths require 'chef/rabbit' chef_handler "Chef::RABBIT::Handler" do source "chef/rabbit" arguments({ :connection => { :host => "your_rabbit_server", :user => "rabbit_user", :pass => "rabbit_pass", :vhost => "/stuff" } :queue => { :name => "some_queue", :params => { :durable => true, ... } }, :exchange => { :name => "some_exchange", :params => { :durable => true, ... } }, :timestamp_tag => "@timestamp" }) supports :exception => true, :report => true end.run_action(:enable) Arguments take the form of an options hash, with the following options: * :connection - http://rubybunny.info/articles/connecting.html * :queue - rabbit queue info to use. name is set to "chef-client" + durable = true by default * :exchange - rabbit exchange to use .default_exchange + durable = true by default * :timestamp_tag - tag for timestamp "timestamp" by default * :blacklist ({}) - A hash of cookbooks, resources and actions to ignore in the change list. = BLACKLISTING: Some resources report themselves as having updated on every run even if nothing changed, or are just things you don't care about. To reduce the amount of noise in your logs these can be ignored by providing a blacklist. In this example we don't want to be told about the GELF handler being activated: chef_handler "Chef::RABBIT::Handler" do source "chef/rabbit" arguments({ :blacklist => { "chef_handler" => { "chef_handler" => [ "nothing", "enable" ] } } }) supports :exception => true, :report => true end.run_action(:enable) = LICENSE and AUTHOR: Copyright 2014 by MTN Satellite Communications Licensed under the Apache License, Version 2.0 (the “License”); you may not use this file except in compliance with the License.
