Would you like to go from first idea to working code much, much faster? Do you currently spend more time satisfying the compiler instead of your clients or end users? Are you frustrated with demanding languages that seem to get in your way, instead of getting the work done? Are you using Rails, and want to dig deeper into the underlying Ruby language? If so, then we've got a language and book for you!Ruby 1.9 is the latest version of Ruby. It has many compelling features, including multinationalization support, new block scoping, and better performance. At the same time, the current Ruby 1.8 is still being maintained and is widely used. We're therefore releasing both the Ruby 1.9 version of the PickAxe (this book) alongside the 1.8 version of the PickAxe. Readers can choose the book that matches their environment.Ruby is a fully object-oriented language, much like the classic object-oriented language, Smalltalk. Like Smalltalk, it is dynamically typed (as opposed to Java or C++), but unlike Smalltalk, Ruby features the same conveniences found in modern scripting languages, making Ruby a favorite tool of intelligent, forward-thinking programmers and the basis for the Rails web framework.This is the reference manual for Ruby, including a description of all the standard library modules, a complete reference to all built-in classes and modules (including all the new and changed methods introduced by Ruby 1.9). It also includes all the new and changed syntax and semantics introduced since Ruby 1.8. Learn about the new parameter passing rules, local variable scoping in blocks, fibers, multinationalization, and the new block declaration syntax, among other exciting new features.

Ruby on Rails es una estructura Web MVC (Model-View-Controller) completa que le ayudará a crear aplicaciones Web de alta calidad, dedicando mucho menos tiempo del que imagina. Concéntrese en la aplicación, y Rails se ocupará de los detalles. Incluso puede escribir aplicaciones que admiten JavaScript sin tener que redactar una sola línea de código. Este libro comienza con un recorrido paso a paso por la creación de una aplicación real, para luego profundizar en el análisis de las características integradas de Rails. Por último, ofrece un enfoque en los recursos de Rails y descubre los métodos más prácticos que utilizan actualmente los desarrolladores. Este manual le enseña, entre otros aspectos, a aprender cómo Rails elimina configuraciones tediosas y tareas de administración local, cómo incorporar a sus aplicaciones Ajax, REST, servicios Web y control de correo electrónico, etc.
