    1. Before anything else, I have to say I really didn t like the style the author chose for the first part of the book In the chapters named Monday to Friday , you go through your first week in a new job, doing pair programming with your colleague Bill While this is fun for about half a page, sentences like Bill walks over to the whiteboard and starts drawing a blablabla get old fast Very fast I m not exactly sure why the author decided on this style, since in my opinion it doesn t add anything to t [...]


    2. Paolo Perrotta s Metaprogramming Ruby Program Like the Ruby Pros is a tour de force on Ruby s Object Model The book goes into considerable depth on how it works, and presents many examples of manipulating the object model to good use The format of first section of the book goes through a week of a pair of Ruby programmers as they try to fix and refactor an existing application, and how they use various metaprogramming spells techniques, idioms, etc The second section is a set of essays talking d [...]


    3. This is a book fills a long standing whole in the Ruby community by laying out a cohesive explanation of the Dark Art we call meta programming So much of Ruby metaprogramming is tribal knowledge and it can be difficult to acquire Even difficult is understanding the underlying rationale for various bits of meta magic This book does a good job of boiling down Ruby metaprogramming into a list of spells , then explains each one in the context of a running narrative.For any Ruby programming struggli [...]


    4. Every Ruby developer should read this book, if only to learn some of the depths of what is possible in the language, and how the ideas from different paradigms OO, message passing, FP can come together with such power.The book is conversational in tone, and the idea of spells discussed throughout provide helpful mnemonics to recognize the concepts in the wild later.I read this after attempting to write Rails plugins a lot of what seemed quite unusual to me or sensible, if a bit quirky now makes [...]


    5. It s a very useful book for those who want to learn about the ruby language anatomy, and how objects work, the book is a bit old using ruby 1.9.3 and rails 2mething but most rules apply regardless of the version you re working on right now.


    6. I will be rereading this book periodically to keep my Ruby skills sharp It clarified concepts I was familiar with Eigenclass and class_eval and instructs on how to skillfully use them He uses examples from several popular projects He knows his stuff.I was impressed with the list of spells ie design patterns he used They are Argument Array Collapse a list of arguments into an array.Around AliasCall the previous, aliased version of a method from a redefined method.Blank SlateRemove methods from an [...]

    8. Metaprogramming Ruby is one of the books that has been taking the ruby programming community by force, and it is easy to see why Metaprogramming has been espoused for quite some time as one of the most compelling features of the language, and for a lot of newcomers to the language it seems a complicated and arcane subject reserved for those who really know the hows and whys of programming in Ruby A book that provides insights into this subject is destined for the bookshelves of rubyists everywhe [...]


    9. Awesome book, all around The first few chapters were fairly easy to follow, and I enjoyed some of the humorous pair programming dialogue that was sprinkled into the story While reading the book, I had a lot of Ah ha moments, when I finally pieces something together which I had learned from a slew of different sources, but never really integrated into a common whole Metaprogramming Ruby does a really good job of taking knowledge that you might have picked up from a variety of different sources an [...]


    10. Metaprogramming Ruby is by far my favorite Ruby book First, it does not treat the reader as a brand new programmer The basics of Ruby are obvious to anyone that has programmed before, and can be picked up as examples are given Thankfully this is not included in this book What is included are the main differences between Ruby and other object oriented languages such as Java, Python, and C This is an area which most other Ruby books completely lack If you are curious how Ruby pulls off it s magic [...]


    11. It s an impressive book that can turn an advanced programming topic like metaprogramming which is often considered the black magic of programming into something accessible and even easy This book mostly pulled that off, but the way it did so was annoying it s written as a stupid, contrived conversation between two programmers, as they learn metaprogramming.The bizarre thing is that the second part of this book simply dumps you into the dark depths of Rails code, though accompanied by readable ex [...]


    12. The author creates a continuing story as a framework around which to present the material I found the narrative annoying, and therefore distracting, so much so that I had to abandon reading it after the second chapter However, material presented is sound, if you can get past the cutesy presentation Otherwise Russ Olsen covers metaprogramming in ruby well in Eloquent Ruby highly recommended.


    13. 4.0 Pretty good resourceMost valuable part for me was just walking through the ruby object model in a structured way rather than just poking at it to learn in irb Then the metaprogramming concepts build well on top of that I definitely learned a lot Though I think it should be emphasized that metaprogramming can create problems than it solves and should be looked as an option vs writing a bunch code that s clear I ll probably refer back to it when developing gems and such.


    14. I didn t read this book, I actually studied it If you consider yourself Senior on Ruby this book should be a recap on what you already know and some new tricks will get to you.If you are a Ruby newcomer then meta programming is a must know if you want to become a decent rubyist and this book is an easy way to start getting there.I compiled a few quizzes mostly out of this book like i usually do gistthub 4221679


    15. Really good introduction to the metaprogramming capabilities of Ruby It s quite an easy read as the author wrote the book as a conversation between two developers this is taken a bit to the extreme in a few places of the book.I think this is an excellent book for someone who doesn t have any background on the metaprogramming features of ruby.


    16. The first half of the book employs a 2nd person narrative point of view that takes some getting used to I would have disliked it has I not been forewarned by other reviewers Though tedious at first, ultimately I think it worked well to present concepts that are then studied in real world applications in the second half of the book.


    17. Good book on meta programming The writing style starts of kind of quirky as a dialogue between an old experienced programmer and his apprentice This quickly got old for me though, whilst it reads easily it is a longhand form of getting ideas across, and makes it harder to skim content.The second part of the book, examines portions of the rails source code, namely activerecord.


    18. This book is a must read for any software developer writing code in Ruby It provides valuable information regarding the structure of Ruby s object model The techniques presented in this book with change your approach to implementing solutions regardless of language.


    19. This is a nice compendium of ruby metaprogramming techniques, and worth having on your shelf My biggest criticism is that it s very repetitive the same technique is shown under different headings, and then it s all repeated again in an appendix.


    20. High level and conceptual, but also idiomatic and filled with examples Exactly the way I like my programming books This was an excellent read because you re dealing with hands on Ruby code on just about every page, so you never lose sight of the engineering, but the lesson is all science.


    21. I really enjoyed this book There are a lot of great tip and tools to learn from it as well as concrete examples There is also a great recap of the Spells learned along the way in the Appendix Which will be handy when one needs to recap an technique.


    22. Terrific book that covers the complete Ruby object model and various patterns and techniques that you can use to manipulate it.I ve been writing Ruby for almost a decade without knowing most of this I so wish I d read this sooner.


    23. This is the most comprehensive resource I have seen on Metaprogramming in Ruby Its easy to read for a advanced topic Explains how a number of great Ruby gems work I feel I am a way capable Ruby Programmer after reading it.


    24. A must read for any Ruby programmer It gives you an overview of the object model in the first couple of chapters and suddenly every single line of code that didn t make much sense in popular libraries is clear as an A class diamond


    25. An awesome book for those who have already wet there feet in ruby and are now itching to expand their knowledge It not only teaches you metaprogramming, but the innards of ruby itself As the author puts it, Metaprogramming is everywhere in Ruby.


    26. I would recommend this book to anyone seriously working with Ruby It made a lot of the code I saw in libraries clear.




    27. Insightful, entertaining and pragmatic A good and straightforward introduction to metaprogramming The structure format was enjoyable.


    28. Great book I always struggled with blocks, procs and Lambda s until I read this book It has some really good examples Wonderful book if you deal with metaprogramming.
