An Introduction to Ruby and Rails An Introduction to Ruby and Rails This paper was originally presented at the Southwest Fox conference in Gilbert, Arizona in October, 2010. http://www.swfox.net An Introduction to Ruby and Rails Rick Borup Information Technology Associates 701 Devonshire Dr, Suite 127 Champaign, IL 61820 Voice: (217) 359-0918 Fax: (217) 398-0413 Email: [email protected] Ruby is a powerful, object-oriented, open-source language with a clean and easily understandable syntax. Originally released to the public in 1995, wide-spread interest in the Ruby language really began to take off in 2003 with the release of the Ruby on Rails® framework. Also known as "RoR" or simply "Rails", Ruby on Rails is an open-source Web framework that makes it possible to quickly and easily create data-based Web applications. Together, the Ruby language and the Ruby on Rails framework can become an exciting and powerful addition to any developer's toolbox. This session introduces both the Ruby language and the Rails framework, focusing on their installation and use on a Windows® platform with a perspective geared toward experienced Visual FoxPro® developers. © 2010 Rick Borup Page 1 of 64 An Introduction to Ruby and Rails Table of Contents

  • Rubabel: Wrapping Open Babel with Ruby Rob Smith1*, Ryan Williamson1, Dan Ventura1 and John T Prince2*
    Smith et al. Journal of Cheminformatics 2013, 5:35 http://www.jcheminf.com/content/5/1/35 SOFTWARE Open Access Rubabel: wrapping open Babel with Ruby Rob Smith1*, Ryan Williamson1, Dan Ventura1 and John T Prince2* Abstract Background: The number and diversity of wrappers for chemoinformatic toolkits suggests the diverse needs of the chemoinformatic community. While existing chemoinformatics libraries provide a broad range of utilities, many chemoinformaticians find compiled language libraries intimidating, time-consuming, arcane, and verbose. Although high-level language wrappers have been implemented, more can be done to leverage the intuitiveness of object-orientation, the paradigms of high-level languages, and the extensibility of languages such as Ruby. We introduce Rubabel, an intuitive, object-oriented suite of functionality that substantially increases the accessibily of the tools in the Open Babel chemoinformatics library. Results: Rubabel requires fewer lines of code than any other actively developed wrapper, providing better object organization and navigation, and more intuitive object behavior than extant solutions. Moreover, Rubabel provides a convenient interface to the many extensions currently available in Ruby, greatly streamlining otherwise onerous tasks such as creating web applications that serve up Rubabel functionality. Conclusions: Rubabel is powerful, intuitive, concise, freely available, cross-platform, and easy to install. We expect it to be a platform of choice for new users, Ruby users, and some users of current solutions. Keywords: Chemoinformatics, Open Babel, Ruby Background tasks. Though it allows the user to access the functionality Despite the fact that chemoinformatics tools have been of the component libraries from one Python script, Cin- developed since the late 1990s [1], the field has yet to fony does not automatically manage underlying data types rally in support of a single library.

  • Calling .NET Code from VFP the Easy Way
    Session E-CALL Calling .NET Code from VFP the Easy Way Doug Hennig Stonefield Software Inc. Email: [email protected] Corporate Web site: www.stonefieldquery.com Personal Web site : www.DougHennig.com Blog: DougHennig.BlogSpot.com Twitter: DougHennig Overview At the German DevCon 2011, Doug’s “Creating ActiveX Controls for VFP Using .NET” session showed how to create .NET components that can be used in Visual FoxPro applications. However, these types of controls suffer from a couple of issues: they have to be registered for COM on the customer’s system and there are limitations in working with .NET Interop in VFP that prevent many things from working correctly. This session shows how Rick Strahl’s wwDotNetBridge eliminates these issues and provides some practical examples of how this tool can be used in your applications. Calling .NET Code from VFP the Easy Way 20th European Visual FoxPro DevCon 2013 © 2013 Doug Hennig (Group .NET) E-CALL • 1 Introduction The Microsoft .NET framework has a lot of powerful features that aren’t available in VFP. For example, dealing with Web Services is really ugly from VFP but is simple in .NET. .NET also provides access to most operating system functions, including functions added in newer version of the OS. While these functions are also available using the Win32 API, many of them can’t be called from VFP because they require callbacks and other features VFP doesn’t support, and accessing this functions via .NET is easier anyway. Fortunately, there are various mechanisms that allow you to access .NET code from VFP applications.

  • Ruby on Rails™ Tutorial: Learn Web Developments with Rails
    ptg8286261 www.it-ebooks.info Praise for Michael Hartl’s Books and Videos on Ruby on RailsTM ‘‘My former company (CD Baby) was one of the first to loudly switch to Ruby on ptg8286261 Rails, and then even more loudly switch back to PHP (Google me to read about the drama). This book by Michael Hartl came so highly recommended that I had to try it, and the Ruby on RailsTM Tutorial is what I used to switch back to Rails again.’’ —From the Foreword by Derek Sivers (sivers.org) Formerly: Founder, CD Baby Currently: Founder, Thoughts Ltd. ‘‘Michael Hartl’s Rails Tutorial book is the #1 (and only, in my opinion) place to start when it comes to books about learning Rails. It’s an amazing piece of work and, unusually, walks you through building a Rails app from start to finish with testing. If you want to read just one book and feel like a Rails master by the end of it, pick the Ruby on RailsTM Tutorial.’’ —Peter Cooper Editor, Ruby Inside www.it-ebooks.info ‘‘Grounded in the real world.’’ —I Programmer (www.i-programmer.info), by Ian Elliot ‘‘The book gives you the theory and practice, while the videos focus on showing you in person how its done. Highly recommended combo.’’ —Antonio Cangiano, Software Engineer, IBM ‘‘The author is clearly an expert at the Ruby language and the Rails framework, but more than that, he is a working software engineer who introduces best practices throughout the text.’’ —Greg Charles, Senior Software Developer, Fairway Technologies ‘‘Overall, these video tutorials should be a great resource for anyone new to Rails.’’ —Michael Morin, ruby.about.com ‘‘Hands-down, I would recommend this book to anyone wanting to get into Ruby on Rails development.’’ —Michael Crump, Microsoft MVP ptg8286261 www.it-ebooks.info RUBY ON RAILSTM TUTORIAL Second Edition ptg8286261 www.it-ebooks.info Visit informit.com/ruby for a complete list of available products.
