Parsetreee gem available for Windows!

Posted by Brian in Rails, tips (January 1st, 2008)

Luis Laverna compiled and released the parsetree gem for Windows. This means that libraries like ruby2ruby, heckle, flog, and even the merb framework are now available to Windows Rubyists.

You need to look at flog. It can show you how bad your code really is.

mongrel_service broken on Windows again.

If you’re working with the mongrel_service gem then you should know that right now there’s a few kinks in the system.

Here’s a quick rundown of the setup for Rails on Windows from scratch:

Download the One Click Ruby Installer and run the setup program.

Open a command prompt and type these commands:

gem update --system
gem install rails
gem install mongrel
gem install win32-service -v '0.5.2'
gem install mongrel_service

The key to this is that the win32-service gem is currently broken, so switching to a previous version (0.5.2) works great for us. Credit for this goes to Luis Laverna, the creator of the mongrel_service gem. See the discussion.

How To Follow Along with Agile Web Development with Rails Second Edition

Posted by Brian in Rails, tips (January 1st, 2008)

This is merely for reference for anyone out there new to Rails or Ruby and trying to work with the Agile book. Version 2.0.2 of Rails is out now and it’s just way too difficult to follow along with the great AWDWR book from Pragmatic. To be successful with that book, you need to use Rails 1.2.3. Here’s how you do it:


If you have a brand new macbook pro, you’re done. It comes equipped with Rails 1.2.3. Start following along with the first Hello World program.

If you’ve accidentally installed Rails 2.0, you can start a Rails 1.2.3 project like this:

sudo gem update --system
sudo gem install rails -v=1.2.3
rails _1.2.3_ depot

where depot is the name of your project.


If you’ve got a Windows machine, start from scratch. Grab The one click ruby installer (Windows installer) and install it.

Next, open up a command prompt and install Rails 1.2.3, and Mongrel

gem update --system
gem install rails -v '1.2.3'
gem install mongrel
gem install mysql

Now just go ahead and follow along with the book. When you’re done, you can update to Rails 2.0 by doing

gem install rails

which will install the latest version of Rails. Your current Rails apps are tied to the version of Rails they are created on. You change the version of Rails the app uses by “freezing gems” (placing a copy of Rails in the app’s vendor/rails folder, or by editing the app’s config/environment.rb file and changing the version specified there. Do a web search for more info on this.

You can specify the version of Rails you want to use by passing it along on the commandline

rails _1.2.3_ old_rails_app
rails _1.2.6_ ready_to_update_app
rails _1.1.6_ legacy app
rails _2.0.2_ new_rails_app

Just make sure you have all of the Rails versions that you want to use on your machine.
