RECIPES FOR OBJEC T-ORIENTED SCRIPTING

Lucas Carlson

& Leonard Richardson

Ruby Cookbook

Why spend time on coding problems that others have already solved when

you could be making real progress on your Ruby project? This updated

cookbook provides more than 350 recipes for solving common problems,

on topics ranging from basic data structures, classes, and objects, to web

development, distributed programming, and multithreading.

Revised for Ruby 2.1, each recipe includes a discussion on why and how

the solution works. You’ll find recipes suitable for all skill levels, from

Ruby newbies to experts who need an occasional reference. With Ruby

Cookbook, you’ll not only save time, but keep your brain percolating with

new ideas as well.
