Descrizione dell’articolo da parte del venditore

Paperback. Have you ever looked at a Phoenix.Router or Ecto.Schema and wondered, "How does that actually work?" You see use, plug, get, and schema, and they just feel like part of the language, but you know they are not.This "black box" is where many developers get stuck. You've probably used quote and unquote for simple tasks, but you are not sure how to combine them into a powerful tool. I've been there.This book is designed to turn that "black box" into a clear, glass one. I will show you that the "magic" of Elixir's best libraries is actually a set of simple, repeatable patterns that you can learn and master. You will move from being confused by this power to being in complete control of it.What's insideThis book is a step-by-step journey, and here is a look at what we will cover: See Your Code as Data: A deep look at the Abstract Syntax Tree (AST), the one concept that makes everything else possible.Master quote and unquote: Learn to read and build new code programmatically.Write Your First Macro: A step-by-step guide to building defmacro, understanding the "Two Timelines" of compile-time and runtime.Control Macro Hygiene: Understand how Elixir protects your variables and how to intentionally break that protection with var.Generate Functions: Learn to use module attributes and compile callbacks (atbefore_compile) to build powerful, multi-part modules.Build Your Own DSL: A hands-on, multi-part case study where we build a mini-testing framework (like ExUnit) from scratch.Demystify use and __using__: Learn how libraries like Phoenix inject code into your modules and how to build your own.Debug Like a Pro: Master the tools (IO.inspect, Macro.to_string, Macro.expand) for troubleshooting your compile-time code.Deconstruct Real-World Code: We'll pull apart Phoenix.Controller, Phoenix.Router, and Ecto.Schema to prove it is all just macros.Who it's meant forThis book is not for the brand-new Elixir developer. This book is for you, the intermediate-to-advanced Elixir programmer who has hit a plateau.This book is for you if: You are comfortable with defmodule and def.You want to understand the "how" behind Phoenix and Ecto, not just the "what."You want to write your own powerful, clean, and reusable libraries.You are ready to move from being an Elixir user to an Elixir architect.Stop letting metaprogramming be a "black box." The most powerful parts of Elixir are open to you. This book is the key. Turn your confusion into confidence, and start writing the code you've always wondered how to build.Get your copy today and unlock the true potential of Elixir. This item is printed on demand.
