Opis:

Do you want to push Ruby to its limits? The Ruby Cookbookis the most comprehensive problem-solving guide to today's hottestprogramminglanguage. It gives you hundreds of solutions to real-world problems,with clear explanations and thousands of lines of code you can use inyour own projects.

From data structures and algorithms, to integration withcutting-edge technologies, the Ruby Cookbook hassomething for every programmer. Beginners and advanced Rubyistsalike will learn how to program with:

  • Strings and numbers
  • Arrays and hashes
  • Classes, modules, and namespaces
  • Reflection and metaprogramming
  • XML and HTML processing
  • Ruby on Rails (including Ajax integration)
  • Databases
  • Graphics
  • Internet services like email, SSH, and BitTorrent
  • Web services
  • Multitasking
  • Graphical and terminal interfaces

If you need to write a web application, this book shows youhow to get started with Rails. If you're a system administrator whoneeds torename thousands of files, you'll see how to use Ruby for this andother everyday tasks. You'll learn how to read and write Excelspreadsheets, classify text with Bayesian filters, and create PDFfiles. We've even included a few silly tricks that were too cool toleave out, like how to blink the lights on your keyboard.

The Ruby Cookbook is the most useful book yetwritten about Ruby. When you need to solve a problem, don't reinventthe wheel: look it up inthe Cookbook.
