• Use standard bundler to easily package, manage, and update ruby gems in the workflow.
• Friendly exception and debug output to the Mac OS X Console.
• Automate saving and loading cached feedback
• Automate rescue feedback items to alfred when something goes wrong.
• Functions to easily load and save user configuration (in YAML)
• Functions for smart case query filter of feedback results.
• Functions for finding the bundle ID, cache and storage paths, and query arguments.
• Functions for reading and writing plist files.

1. cached feedback are saved and closed automatically, call to put_cached_feedback is not required.

require 'rubygems' unless defined? Gem
require "bundle/bundler/setup"
require "alfred"

Alfred.with_friendly_error do |alfred|
  fb = alfred.feedback

  fb.add_file_item(File.expand_path "~/Applications/")

  puts fb.to_alfred(ARGV)
end

Code are wrapped in Alfred.with_friendly_error block. Exceptions and debug messages are logged to Console log file ~/Library/Logs/Alfred-Workflow.log.

require 'rubygems' unless defined? Gem
require "bundle/bundler/setup"
require "alfred"

def my_code_with_something_goes_wrong
  true
end

Alfred.with_friendly_error do |alfred|
  alfred.with_rescue_feedback = true

  fb = alfred.feedback

  if my_code_with_something_goes_wrong
    raise Alfred::NoBundleIDError, "Wrong Bundle ID Test!"
  end
end

require 'rubygems' unless defined? Gem
require "bundle/bundler/setup"
require "alfred"

Alfred.with_friendly_error do |alfred|
  alfred.with_rescue_feedback = true
  alfred.with_cached_feedback do
    # expire in 1 hour
    use_cache_file :expire => 3600
    # use_cache_file :file => "/path/to/your/cache_file", :expire => 3600
  end

  if fb = alfred.feedback.get_cached_feedback
    # cached feedback is valid
    puts fb.to_alfred
  else 
    fb = alfred.feedback
    # ... generate_feedback as usually
    fb.put_cached_feedback
  end
end

fb = alfred.feedback
fb.add_item(:uid          => "uid"          ,
            :arg          => "arg"          ,
            :autocomplete => "autocomplete" ,
            :title        => "Title"        ,
            :subtitle     => "Subtitle"     ,
            :match?       => :all_title_match?)

fb.add_file_item(File.expand_path "~/Applications/", :match? => :all_title_match?)

:title_match? and :all_title_match? are built in.

To define your new matcher

Module Alfred
  class Feedback
    class Item
      # define new matcher function here
      def your_match?(query)
        return true
      end
    end
  end
end

Check the code in alfred/feedback/item.rb for more information.

1. ruby crashes

One of the major reason for ruby crash is native extensions. Check the file bundle/bundler/setup.rb under the workflow folder; make sure it does not mixed up with rvm like this:

# ......
$:.unshift File.expand_path("#{path}/../../../../../../../../.rvm/gems/ruby-2.0.0-p247@global/gems/plist-3.1.0/lib")
$:.unshift File.expand_path("#{path}/../#{ruby_engine}/#{ruby_version}/gems/alfred-workflow-1.11.3/lib")
$:.unshift File.expand_path("#{path}/../../../../../../../../.rvm/gems/ruby-2.0.0-p247@global/gems/json-1.8.0/lib")

After checking out the source, run:

$ rake newb

This task will install any missing dependencies, run the tests/specs, and generate the RDoc.
