0.??Getting Started When you program a computer, you have to "speak" in a language your computer understands: a programming language. There are lots and lots of different languages out there, and many of them are excellent. In this tutorial I chose to use my favorite programming language, . Aside from being my favorite, Ruby is also the easiest programming language I have seen (and I've seen quite a few). In fact, that's the real reason I'm writing this tutorial: I didn't decide to write a tutorial, and then choose Ruby because it's my favorite; instead, I found Ruby to be so easy that I decided there really ought to be a good beginner's tutorial which uses it. It's Ruby's simplicity which prompted this tutorial, not the fact that it's my favorite. When you write something in a human language, what is written is called text. code . If you come across something you don't understand, or you have a question which wasn't answered, write it down and keep reading! Windows Installation Global Properties
Learn Ruby with the EdgeCase Ruby Koans Ruby Object Oriented Programming From Techotopia Purchase and download the PDF and ePub versions of this Ruby eBook for only $8.99 Ruby is an object oriented environment and, as such, provides extensive support for developing object-oriented applications. The area of object oriented programming is, however, large. [edit] What is an Object? An object is a self-contained piece of functionality that can be easily used, and re-used as the building blocks for a software application. Objects consist of data variables and functions (called methods) that can be accessed and called on the object to perform tasks. Just about everything in Ruby, from numbers and strings to arrays is an object. [edit] What is a Class? Much as a blueprint or architect's drawing defines what an item or a building will look like once it has been constructed, a class defines what an object will look like when it is created. New classes can be created based on existing classes, a concept known as inheritance. [edit] Defining a Ruby Class
The Rubyist Historian: The Series | Jason Heppler The Rubyist Historian: The Series Coming off my recent post on How I Learned Code, I’ve decided to write a series of blog posts that will introduce historians to the basics of Ruby that I will eventually publish as a free ebook. My hope is to write an accessible introduction to Ruby and demonstrate not only how to write small programs but also think about ways programming can help scholars in their everyday tasks. Although I’m aiming this at historians, my hope is that anyone interested in humanist computing (or Ruby in general) will find this useful. You can find copies of code examples in the Rubyist Historian Github repository. Contents 1: Getting Started 2: Methods and Classes 3: Loops and Control Structures 4: Arrays and Hashes 5: Working with Advanced Data 6: Randomness 7: Our First Program Acknowledgements The structure, examples, and topics that comprise this blog series are directly inspired by and drawn from Prof.

Jacques Crocker: Create a Library of Snippets Jacques Crocker is a Rails Jedi based out of Seattle who loves working on early-stage startup ideas and launching new products. His advice for intermediate Ruby devs is to "build an executable snippet library." "Every time I write some code that I think could have potential for reuse in another project in the future, I copy and paste it into a unit test within a private 'snippets' project.
