Compilers are a fun challenge to write. Follow me as I explore some ideas on language design.
Last week, we learned about the history of the compiler and about the lexer. This week we are talking about parsing.
This week I am talking about the parts of the compiler, doing a deep dive into the Lexer and Parser and showing how to build the Lexer and Parser in Python. At the end of this post, we should have a working lexer and parser.
This week, I am doing something new. Something most people will shy away from. But not me! Why? Because I am a masochist. So what am I doing? I am going to start creating a completely new language.
Too often when we speak about Test Driven Development, or TDD, we speak about it as if it’s an investment. I think it’s time to change the conversation and talk about TDD as if it is an essential engineering step.
