os01 VS Crafting Interpreters

Write an OS from scratch

(Here is the link - didn't quite get the image/link combo right in the original post!). I'm writing a series of posts about coding your own operating system. After reading Operating Systems: From 0 to 1 I found that some of the code does not work, so this first post walks you through writing a bootloader similar to that of chapter 7. It also adds some context that I would have found useful when I originally read the book, such as how 16-bit real mode works and some assembly programming information. I'm hoping to take a different approach to posts in the series by borrowing pieces of other operating systems and discussing how they are implemented in an effort to keep things simple and focus on fundamentals (even Linus started out with a detailed reading of MINIX).

Very quickly skimming through the various chapters, it appears that this is gentle introduction as attention has been made on clear and verbose explanations, supplemented with diagrams. Comparable other "courses" could be osdev101 [1] and "Writing an operating system from scratch" [2].

You need to be aware of how it works on a hardware level but probably not an expert, for a better explanation see: https://github.com/tuhdo/os01

Build an Interpreter (Chapter 14 on is written in C)

I’m guessing you’ll have to work with the scopes in the resolver:

I'm late to the party, but I want to say thank you for sharing this. It's inspiring to look at how much you've built and (hopefully) enjoyed the process of building! I'm loving everything -- your site, your language design, your docs, your builtin libraries, your dev tools. Beyond impressive. People like you are the ones who make HN one of my best places on the internet.

For context on where I'm coming from, about two weeks ago I picked up Crafting Interpreters [1] for fun. I'm finding your clear-yet-concise Compiler internals [2] to be particularly compelling reading, and jumping back and forth between those "how this all works" docs and the live example of this language you actually built do a WASM-compiled tree-blowing-in-the-wind animation is just... just wow. So freaking cool!

I also enjoyed reading the comment thread that inspired you to start on Yaksha and seeing how this project has a wholesome start as inspiration-by-programming-hero. I hope you recognize that a few years later you've now ascended from inspiree to inspirer. I also hope you're still having tons of fun building out Yaksha!

There are books which will talk you through the process. Crafting Interpreters is highly spoken of; I used Writing an Interpreter in Go, because I like Go. Then there's Compilers: Principles, Techniques, and Tools (the "Dragon Book"). This is considered heavy, but a classic, it's been around since '86.

I cannot recommend Crafting Interpreters by Robert Nystrom enough, it covers a lot of the stuff you need to know, completely for free.

Crafting Interpreters is a fun primer on language design. It has a complete roadmap to build a fairly simple language, twice. There are some topics it won't touch on, like static type systems, but it provides a great introduction so that you can start tinkering and learn by doing.
