Pedro Henrique and I have written Micro C: Aprendendo Compiladores, a practical introduction to how compilers work. The book uses the small Micro C language to guide readers through the main stages of a compiler: lexical and syntax analysis, syntax-tree construction, semantic checks, intermediate-code generation, and translation to x86-64 Assembly.
The explanations combine diagrams, implementation excerpts, and progressive exercises to connect compiler theory with working code. It is intended for students, instructors, and curious programmers who want to understand a compiler from end to end and experiment with building one of their own. The book is written in Brazilian Portuguese.
You can also explore the Micro C compiler source code on GitHub.
