part one: persistent data structures part two: immutable.fnl optimizations The two previous posts were not related to the compiler itself, but were kicked off by the start of the compiler development. I’d say this project was the reason that I made proper immutable data structures for Fennel and Lua.

part two: immutable.fnl optimizations part three: parsing Somewhere in 2019 I started a project that aimed to bring some of Clojure features to Lua runtime - fennel-cljlib. It was a library for Fennel that implemented a basic subset of clojure.core namespace functions and macros.

The unexpected part! I liked hacking on Lox in Zig a lot, so I decided it would be great to make some changes to the language. It should be good for a better understanding of the book’s material, and probably will be a lot of fun!

This is a second post about the Crafting Interpreters book by Robert Nystrom. In the first post, I’ve described my experience with the first half of the book, and the challenges of using a different language with different idioms and practices. This post will be no different, although I have a bit more to discuss, and the contents aren’t actually ~2-year-old weak impressions and remembrances.

Today I would like to discuss the Crafting Interpreters book by Robert Nystrom. It’s a book about designing an interpreter for a dynamic programming language called Lox. Well, not exactly. It’s split into two parts - in the first is about crafting a tree-walking interpreter, and the second is about writing a complete bytecode VM.
