Get introduced to the concept of metaprogramming. Learn how to level up your programming skills by discovering the full potential of the macro system in Elixir. Understand the ins and outs of metaprogramming at a fundamental level and write incredible libraries by doing more with less code.

Metaprogramming in Elixir

## Using the tags text file
We’ve done great till now, but our goal is to create a first-class DSL. A single tag macro simply won’t cut it. Let’s elevate our sophistication by supporting all 117 valid HTML tags. We could write a hundred macros by hand, but let’s use the techniques we learned in the chapter [Advanced Compile-Time Code Generation](https://www.educative.io/courses/metaprogramming-elixir/custom-language-constructs) to save time and effort. As before, a quick internet search turned up a complete list of HTML tags. After a copy and paste into a flat text file, we end with a file of line-delimited tags.

Let's create a DSL that supports the entire HTML spec with macros.
