When you go to bb-ruby gem readme, there is an instruction how to extend it with your own translations:

my_block = {
  'Quote' => [
    /\[quote(:.*)?=(.*?)\](.*?)\[\/quote\1?\]/mi,
    '<div class="quote"><p>\2</p><block>\3</block></div>',
    'Quote with citation',
    '[quote=mike]please quote me[/quote]',
    :quote
  ],      
}

text.bbcode_to_html(my_blockquote)

This method works quite good but well... it's way to inconvenient. Where should we put our translation? In our model? Should we create a different model which would store our costume translations? Nah... There is really easy and clean way to add new (and overwrite already existing) translations into a bbcode parser.

Create in your app initializers directory (/config/initializers/) a file called bb-ruby.rb. Below you can see an example with [spoiler][/spoiler] tag:

module BBRuby
  if @@tags
    @@tags['Spoiler'] = [
      /\[spoiler\](.*?)\[\/spoiler\1?\]/mi,
      '<span class="spoiler">\1</span>',
      'spoiler',
      '[spoiler]spoiler[/spoiler]',
      :spoiler]
  end
end

And how to overwrite existing translation? Just replace it with new one. Below example which replaces standard "Link" rule, with same rule but with rel="nofollow":

@@tags['Link'] = [
  /\[url=(.*?)\](.*?)\[\/url\]/mi,
  '<a href="\1" rel="nofollow">\2</a>',
  'Hyperlink to somewhere else',
  'Maybe try looking on [url=http://google.com]Google[/url]?',
  :link]

Sometimes seed files can get messy and big. It can be real pain it the ass to manage them. Here is fast way to split single seeds.rb file:

Create directory called seeds in your db/ directory (mkdir ./db/seeds)
Remove all stuff from seeds.rb and move it into your newly created files under db/seeds/ directory (put them accordingly to your own app logic)
Paste code presented below into seeds.rb file
Run rake db:seed

Seeds.rb file source code:

# coding: utf-8

%w{
  filename1 filename2 filename3...filenameN
}.each do |part|
  require File.expand_path(File.dirname(__FILE__))+"/seeds/#{part}.rb"
end

Why haven't I use auto-include and instead I've listed all the files? Well I wanted to maintain my seed parts load order so those parts will be loaded accordingly to my order (not based on file names).
