Meta-programming in Ruby - course 4900 rub. from ThinkNetica, training 1 week, Date November 27, 2023.

Let's look at the concept of "metaprogramming" with examples in different languages. Let us repeat the most common techniques and methods.

As a result, you will be able to:
Learn to use the core set of metaprogramming tools in Ruby. Consolidate the information received in a small library with a self-written DSL as homework.

Let's take a closer look at the dynamic nature of Ruby and learn how to create objects with environment-dependent behavior, be it variables from the execution context or program startup settings. We will consider in detail the use of proc and lambda, when creating a DSL and separately, in isolation from any context.

As a result, you will be able to:
Learn to dynamically create extensions for classes and objects from a set of options and parameters. Consolidate new knowledge in practice by improving the library API from the first homework.

Let's study the code of large ruby ​​projects that use metaprogramming. Let's compare their strengths and weaknesses with the approaches studied in previous classes.

As a result you:
You will close the remaining gaps on the topic of metaprogramming in Ruby. Look at typical applications of metaprogramming in well-known projects through the lens of the experience gained in class.
