One of the major problem which prevent the migration to Ruby 1.9 is the lack of the porting of ruby-debug.

Here the steps I followed to made it working on my MacBook with Multiruby:


sudo gem install rake-compiler ruby_core_source --no-rdoc --no-ri
sudo gem install ruby-debug19 --no-rdoc --no-ri


I hope it works for you too!

How many times do you heard you should separate content from behavior? Never? Hmmm don’t try to cheat me.. So, why do you still use :confirm option for link_to helper?

Here a little snippet to archive our goal, and as extra bonus, you get it i18n:


<script type="text/javascript">
window._authenticity_token = "";
</script>

t(:’asset.destroy’),
:class => “delete”,
:’data-confirm’ => t(:’asset.destroy_confirm’) %>


$(document).ready(function(){
$(".delete").bind("click", function() {
if(window.confirm($(this).attr("data-confirm"))) {
$.ajax({
url: $(element).attr("href"),
data: {
_method: "delete",
authenticity_token: window._authenticity_token
},
type: 'post',
dataType: 'script'
});
}
return false;
});
});


I’m back and I wanna share those simple snippets with you:

class Hash def deep_has_key?(key) self.has_key?(key) || any? {|k, v| v.deep_has_key?(key) if v.is_a? Hash} end alias :deep_include? :deep_has_key? alias :deep_key? :deep_has_key? alias :deep_member? :deep_has_key?

def deep_has_value?(value) self.has_value?(value) || any? {|k,v| v.deep_has_value?(value) if v.is_a? Hash} end alias :deep_value? :deep_has_value? end

Example:
{:a => {:c => 'c'}, :b =>{:d => {:e => 'e'}}}.deep_has_key?(:e) # => true {:a => {:c => 'c'}, :b =>{:d => {:e => 'e'}}}.deep_has_key?(:z) # => false

{:a => {:c => ‘c’}, :b =>{:d => {:e => ’e’}}}.deep_has_value?(’e’) # => true {:a => {:c => ‘c’}, :b =>{:d => {:e => ’e’}}}.deep_has_value?(‘z’) # => false

I took inspiration from the Pratik Naik post, and realized a more simplistic version of its Rails single file app. My implementation has only Rails as unique dependency.
require 'rubygems' require 'action_controller' require 'webrick' require 'webrick_server'

class HelloWorldController ‘Hello World!’ end end

DispatchServlet.dispatch :port => 3000, :server_root => File.dirname(FILE)

Update 2008-06-04: I just wrote another version which also uses ActiveRecord and a template.
require 'rubygems' require 'activerecord' require 'action_controller' require 'webrick' require 'webrick_server'

ActiveRecord::Base.establish_connection( :adapter => ‘sqlite3’, :database => ’tiny_rails.sqlite3’, :timeout => 5000)
