Installed latest Rubygems which broken my dev environment.

One to remember next time something screwy happens, and I am to lazy to use rvm

sudo gem uninstall rubygem-update -v 1.8.10
sudo gem install rubygems-update -v 1.5.2
sudo update_rubygems _1.5.2_

In order to start moving with building Warcraft AddOns you might want to extract the Blizzard UI Code and Art bundles. A little bit fiddly but…

/Applications/World\ of\ Warcraft/World\ of\ Warcraft.app/Contents/MacOS/World\ of\ Warcraft -console

On the login screen hit /~ to open the console and type

> exportInterfaceFiles code
> exportInterfaceFiles art

You should now have two new directories in your World Of Warcraft (/Applications/World of Warcraft/) BlizzardInterfaceArt and BlizzardInterfaceCode directory.

My first World Of Warcraft AddOn, ok so I found a nice tutorial on WowWiki – http://www.wowwiki.com/AddOn_programming_tutorial/Introduction .

- HelloWorld.toc

## Interface: 40000
## Title: Hello World!
## Notes: My first AddOn
HelloWorld.lua
HelloWorld.xml

- HelloWorld.lua

function HelloWorld()
  print("Hello World!");
end

- HelloWorld.xml

<Ui xmlns="http://www.blizzard.com/wow/ui/"

And there if you look in the chat console ‘Hello World!’. Kungla is so impressed he needs to have a proper long sit down.

This

redirects = []
redirects << params[:redirect_to] || request.referrer

…does not mean this…

redirects = []
redirects << (params[:redirect_to] || request.referrer)

…it means this.

redirects = []
(redirects << params[:redirect_to]) || request.referrer

Having used Rails I18n translations in yaml for some time, we’ve recently started thinking about how users might want to customise content on the fly, without editing flat files and reloading our application. In my mind it should read from the database.

I found the Il8n Backend Database plugin, however it appears its not Rails 3 compliant yet and we can cope with and probably should build the interface for updating our own translations

https://github.com/dylanz/i18n_backend_database

It seems there was support for ActiveRecord in the i18n gem, but it has since been moved out into the i18n-active_record gem.

./Gemfile

gem 'i18n-active_record', 
  :git => 'git://github.com/svenfuchs/i18n-active_record.git',
  :require => 'i18n/active_record'

./config/initializers/i18n.rb

I18n.backend = I18n::Backend::ActiveRecord
Translation  = I18n::Backend::ActiveRecord::Translation

./db/migrate/20101218175356_create_translations.rb

class CreateTranslations < ActiveRecord::Migration

  def self.up
    create_table :translations do |t|
      t.string   :locale
      t.string   :key
      t.text     :value
      t.text     :interpolations
      t.boolean  :is_proc, :default => false
    end
  end

  def self.down
    drop_table :translations
  end

end

irb

irb(main):001:0> I18n.t('loathsome')
=> "loathsome"
irb(main):002:0> Translation.create(:locale => :en, :key => 'loathsome', :value => 'dave')
=> #<I18n::Backend::ActiveRecord::Translation id: 1, locale: :en, key: "loathsome", value: "dave", interpolations: nil, is_proc: false>
irb(main):003:0> I18n.t('loathsome')
=> "dave"

So fairly simple start, it shouldn’t be too difficult to build an interface to handle this.

You can even keep the existing flat files as a fallback if the translations don’t exist in the database.

./config/initializers/i18n.rb

I18n.backend = I18n::Backend::Chain.new(I18n::Backend::ActiveRecord.new, I18n.backend)
Translation = I18n::Backend::ActiveRecord::Translation

This week has been an interesting one, and its all come at once.

Abominable Iron Sloth

For a start, The Abominable Iron Sloth album has finally seen its release on the 27th April after 4 fours of development hell. The band asked for funding from its fans after the debut release and tour. And it seems to have been one tragedy after another for them, what keeps you down only makes you stronger, eh? And here it is, arrived today with a thanks from Justin.

Stabbing Eden

Pledge Music also got their first Grindcore band on board, Stabbing Eden and I am mightily impressed what what I’ve heard so far so I one of the first to pledge. Their project to fund the recording of their 2nd album “A Second Reason To Hate Us” was launch on the 27th April.

Funeral For A Friend

Firstly, we had Madina Lake, then Tab The Band, but now the biggest metal band so far Funeral For A Friend who went live on Monday, and made their target within 36 hours which is a first for us. Well done those men, but its not over yet.

Thomas Truax

Last but not least, a man we stumbled across lately for a random zombie event in Eastbourne. The very quirky, very eccentric Thomas Truax. If only I could afford one of his famous Sister Spinster contraptions.

Just playing with the new Facebook widgets to see if we can get anything useful out of them.

Finally got around to sorting out autotest on this ubuntu box, I remembered reading on Mr JohnC’s blog about it. Also found a rather nice article on Autotest notifications on Ubuntu using lib-notify

vi ~/.autotest

module Autotest::GnomeNotify
 
  # Time notification will be displayed before disappearing automatically
  EXPIRATION_IN_SECONDS = 2
  ERROR_STOCK_ICON = "gtk-dialog-error"
  SUCCESS_STOCK_ICON = "gtk-dialog-info"
 
  # Convenience method to send an error notification message
  #
  # [stock_icon]   Stock icon name of icon to display
  # [title]        Notification message title
  # [message]      Core message for the notification
  def self.notify stock_icon, title, message
    options = "-t #{EXPIRATION_IN_SECONDS * 1000} -i #{stock_icon}"
    system "notify-send #{options} '#{title}' '#{message}'"
  end
 
  Autotest.add_hook :red do |at|
    notify ERROR_STOCK_ICON, "Tests failed", "#{at.files_to_test.size} tests failed"
  end
 
  Autotest.add_hook :green do |at|
    notify SUCCESS_STOCK_ICON, "All tests passed, good job!", ""
  end
 
end
