Are you familiar with this code?
if error?
puts "Sorry, error occured..."
exit 1
end
Just replace that with:
abort "Sorry, error occured..." if error?
Simple and beautiful.

Integrity is a Continuous Integration server solution which is very easy to set up, especially when you work with Git projects. In this short tutorial, I am going to show you hot to get up and running with Integrity in a couple of simple steps. We are going to build a box with Ruby Enterprise, Passenger and Nginx as a web server.
First step is to get all the build essentials required to compile Ruby and Passenger.
sudo apt-get install build-essential
Now let’s create a directory, where we can download software to:
mkdir ~/src
cd src
Ruby Enterprise Edition requires OpenSSL, Readline, Zlib development libraries. We also want to install SQLite 3 development package, because Integrity currently only works with SQLite.
sudo apt-get install libssl-dev libreadline-dev libz-dev libsqlite3-dev
Now, we have to download Ruby Enterprise edition and install it:
wget http://rubyforge.org/frs/download.php/64475/ruby-enterprise-1.8.7-20090928.tar.gz
tar -zxf ruby-enterprise-1.8.7-20090928.tar.gz
cd ruby-enterprise-1.8.7-20090928/
sudo ./installer
Let’s symlink the executables to some standard path:
cd /opt/ruby-enterprise-1.8.7-20090928/bin/
for i in *; do sudo ln -s /opt/ruby-enterprise-1.8.7-20090928/bin/$i /usr/local/bin/$i; done
Ruby Enterprise automatically installs Passenger gem. Let’s use it to install Nginx:
sudo passenger-install-nginx-module --auto --auto-download
Installer will ask you to choose installatio directory. Just confirm the default.
Integrity come as a gem. We will also add the IRC notification mechanism. Here I’m using Gemcutter as a repository of choice.
sudo gem install gemcutter
gem tumble
sudo gem install integrity integrity-irc shout-bot
sudo gem install do_sqlite3 -v0.9.11
Make sure that data_objects, data_mapper and do_sqlite3 are the same and only version in Rubygems. Otherwise we can have problems where wrong versions are being loaded.
Now, let’s create a place where we want to install our own instance of Integrity:
sudo mkdir /apps
sudo /opt/ruby-enterprise-1.8.7-20090928/bin/integrity install /apps/integrity --passenger
Notice the --passenger option. It tells the installer to create Passenger friendly directory layout.
Last things to do is actual configuration. We have to tell Nginx and Passenger that we want to run our new app:
sudo vim /opt/nginx/conf/nginx.conf
Modify the server section to look similar to this:
server {
listen 80;
server_name localhost;
root /apps/integrity/public;
passenger_enabled on;
}
Integrity comes with two configuration files. Let’s tell the app what domain it’s going to use editing this file:
sudo vim /apps/integrity/config.yml
Also, we want to add the IRC notifier:
sudo vim /apps/integrity/config.ru
Add this after current require lines:
require "integrity/notifier/irc"
Next, we have to migrate the SQLite database like so:
sudo /opt/ruby-enterprise-1.8.7-20090928/bin/integrity migrate_db /apps/integrity/config.yml
Fix the permissions
sudo chown -R `whoami`:nogroup /apps
sudo chmod -R g+w /apps
Start Nginx server
sudo /opt/nginx/sbin/nginx
Voila! We have our Integrity server up and running! Go launch the browser and go to the domain you have chosen before. You are probably going to work with Git. Make sure you have git-core package installed.
Recently, I was porting an Merb and Rails application from DataMapper to Sequel. It is pretty much straightforward with Merb, as you only have to specify use_orm :sequel in your init.rb file to get Sequel configured automatically.
With Rails you have to do this manually eg.:
DB = Sequel.connect('mysql://localhost/database')
or… use my new plugin rails_sequel.
rails_sequel is a simple plugin which loads Sequel, reads database.yml file and adds missing methods such as to_param or new_record?.
You can install it like any other Rails plugin:
script/plugin install git://github.com/pusewicz/rails_sequel.git
Alternatively you can install a gem:
gem install gemcutter
gem tumble
gem install rails_sequel
Load the gem in environment.rb
Rails::Initializer.run do |config|
config.gem 'rails_sequel', :lib => 'rails_sequel', :source => 'http://gems.github.com'
end
You might want to remove ActiveRecord framework in environment.rb file as well:
config.frameworks -= [ :active_record ]
