Create your own programming language with Rust

This repository contains the codes and the contents for createlang.rs

Why am I writing this book?

The book arises from my frustration of not finding modern, clear and concise teaching materials that are readily accessible to beginners like me who wants to learn a bit on how to create their own programming language.

The following are my guidelines

"If you don't know how compilers work, then you don't know how computers work" ¹

"If you can’t explain something in simple terms, you don’t understand it" ²

Requirements

Make sure you have

1. Rust installed
2. Cloned this repository (follow the instructions in each chapter)
3. LLVM v10.0 installed (Debina/Ubuntu or macOS) to run and test locally cargo test --tests

To build the book locally, navigate to the book subdirectory and follow the instructions in mdbook.
