Ruby in Twenty Minutes

Introduction This is a small Ruby tutorial that should take no more than 20 minutes to complete. It makes the assumption that you already have Ruby installed. Interactive Ruby Ruby comes with a program that will show the results of any Ruby statements you feed it. Open up IRB (which stands for Interactive Ruby). If you’re using macOS open up Terminal and type irb, then hit enter. irb(main):001:0> Ok, so it’s open. Type this: "Hello World" irb(main):001:0> "Hello World" => "Hello World" Ruby Obeyed You! What just happened? irb(main):002:0> puts "Hello World" Hello World => nil puts is the basic command to print something out in Ruby. Your Free Calculator is Here Already, we have enough to use IRB as a basic calculator: irb(main):003:0> 3+2 => 5 Three plus two. irb(main):004:0> 3*2 => 6 Next, let’s try three squared: irb(main):005:0> 3**2 => 9 In Ruby ** is the way you say “to the power of”. irb(main):006:0> Math.sqrt(9) => 3.0 Ok, wait, what was that last one?

The Best Way to Learn Rails I come from a PHP background, but these days, I'm a full-time Rails developer. The difficulty for most people who make the switch lies in the learning curve that’s involved. Once you've become proficient in a language or framework, switching to a new one feels like an unnecessary (and time-consuming) challenge. However, learning Ruby and Rails is actually pretty easy! This article details a full lesson plan that will get you up and running in no time! You might think learning Ruby is the most important step, and this is probably the part where everyone stops learning and just sticks with their current framework. Work through the Try Ruby exercises. The most recommended tool for dipping into Ruby's syntax is the Try Ruby website. Once you’ve worked through these exercises a couple of times, you'll have a solid base. Run gem install rails to install Rails. If you want to learn Rails, you’ll of course need to install it on your machine. Next, you need to install Rails. Great!

Ruby Tutorial with Code Samples Why's (Poignant) Guide to Ruby Learn to Program, by Chris Pine A Place to Start for the Future Programmer I guess this all began back in 2002. I was thinking about teaching programming, and what a great language Ruby would be for learning how to program. I mean, we were all excited about Ruby because it was powerful, elegant, and really just fun, but it seemed to me that it would also be a great way to get into programming in the first place. Unfortunately, there wasn't much Ruby documentation geared for newbies at the time. Some of us in the community were talking about what such a "Ruby for the Nuby" tutorial would need, and more generally, how to teach programming at all. And it wasn't very good. What saved me was that I made it really easy for people to contact me, and I always tried to help people when they got stuck. A couple of years later, it was getting pretty good. :-) So good, in fact, that I was ready to pronounce it finished, and move on to something else.

You can find here a link to an online copy of the book « Programming Ruby », by Andrew Hunt & Dave Thomas. Current development version is 1.9.2-p180. Alongside with Ruby, I’ve discovered the joys of a very neat and nicely designed web application framework called Ruby on Rails . Some of my Ruby code here , oldish ciphers implemented in Ruby following the Test-Driven Development principle. A few years ago, a non-profit association ( in French) was established in France to help further spread Ruby usage and love. Some pictures taken at Solutions Linux 2009 here on Flickr!
