Write code that writes code with Elixir macros. Macros make metaprogramming attainable and outline the language itself. during this e-book, you will the right way to use macros to increase the language with quickly, maintainable code and proportion performance in methods you by no means notion attainable. you will find easy methods to expand Elixir along with your personal top notch positive aspects, optimize functionality, and create domain-specific languages.

Metaprogramming is one in every of Elixir's maximum good points. perhaps you will have performed with the fundamentals or written a number of macros. Now you must take it to the subsequent point. This booklet is a guided sequence of metaprogramming tutorials that take you step-by-step to metaprogramming mastery. you are going to expand Elixir with strong beneficial properties and write speedier, extra maintainable courses in methods unequalled by way of different languages.

You'll begin with the fundamentals of Elixir's metaprogramming method and learn how macros have interaction with Elixir's summary structure. Then you are going to expand Elixir together with your personal top notch beneficial properties, write a checking out framework, and notice how Elixir treats resource code as construction blocks, instead of rote strains of directions. you will proceed your trip by utilizing complicated code new release to create crucial libraries in strikingly few traces of code. ultimately, you will create domain-specific languages and study while and the place to use your abilities effectively.

When you are performed, you have got mastered metaprogramming, received insights into Elixir's internals, and feature the boldness to leverage macros to their complete strength on your personal projects.
