How Ruby Works Under the Hood Ruby is a powerful programming language with a focus on simplicity, but beneath its elegant syntax it performs countless unseen tasks. Ruby Under a Microscope gives you a hands-on look at Ruby’s core, using extensive diagrams and thorough explanations to show you how Ruby is implemented (no C skills required). Author Pat Shaughnessy takes a scientific approach, laying out a series of experiments with Ruby code to take you behind the scenes of how programming languages work. You’ll even find information on JRuby and Rubinius (two alternative implementations of Ruby), as well as in-depth explorations of Ruby’s garbage collection algorithm. Ruby Under a Microscope will teach you: How a few computer science concepts underpin Ruby’s complex implementation How Ruby executes your code using a virtual machine How classes and modules are the same inside Ruby How Ruby employs algorithms originally developed for Lisp How Ruby uses grammar rules to parse and understand your code How your Ruby code is translated into a different language by a compiler No programming language needs to be a black box. Whether you’re already intrigued by language implementation or just want to dig deeper into Ruby, you’ll find Ruby Under a Microscope a fascinating way to become a better programmer. Covers Ruby 2.x, 1.9 and 1.8


Well known for his coding expertise and passion for the Ruby programming language, Pat Shaughnessy blogs and writes tutorials at He also develops Ruby applications at management consulting firm McKinsey & Co. Shaughnessy is a regular presenter on the Ruby conference circuit, and his articles and presentations have been featured in the Ruby Weekly newsletter, the Ruby5 podcast, and The Ruby Show.


@ lili 这本书不光读了解Ruby有用,对了解语言虚拟机也很有帮助 @ 机械唯物主义 非常清晰地介绍了ruby内部一些重要东西的实现,推荐所有的ruby程序员看一看。 @ Kymair 这书真有意思!就喜欢这种挖掘内部机制的书了,但又图文并茂不枯燥! @ vmrand 知其然,知其所以然。 @ Fu 理解一门语言,最好的方法就是看它是如何被实现的,想要理解 python,非《Python 源码剖析》莫属,想要理解 ruby,非这本书莫属 @ Fu 理解一门语言,最好的方法就是看它是如何被实现的,想要理解 python,非《Python 源码剖析》莫属,想要理解 ruby,非这本书莫属 @ 壮壮 看中文的就当读了 @ Pepsin 过了一定时期后对这个就不是太感兴趣了 @ fuzhli 读完了斧头书、ruby元编程,再读这本,有种豁然开朗的感觉。 @ lili 这本书不光读了解Ruby有用,对了解语言虚拟机也很有帮助
