I'm working on implementing a programming language all my own

Summary

To the surprise of literally no one, I'm working on implementing a programming language all my own Inspired by conversation at a recent Future of Coding event, I decided I’d write up a little something about the programming language I’ve been working on (for what feels like forever) before I’ve gotten it to a totally shareable state. I have a working interpreter that I’m pretty pleased with, but I don’t yet have an interactive environment for creating, exploring, debugging, and running code — I have this idea for a Smalltalk-flavored infinite canvas dev experience that’ll work in the browser. Hoping that’ll be ready soon(ish)! Author’s note: Cutting in real fast from the future with an after-the-fact update! I pulled together a relatively simple, standalone playground for folks to explore Baba Yaga a bit more! Meet Baba Yaga! Baba Yaga started as a purely aesthetic endeavor. Like a beaver drawn to slowing the flow of a river, I had this idea that was haunting me about what I wanted a language to look like on screen and kinda worked backwards from there. To start, I wrote a few fantasy programs, and then started to think through how to get that code to run. I have no intention whatsoever of Baba Yaga becoming anything but a curiosity and an exploratory project for me. Because of this, it is really, really biased towards the things I adore in a programming experience, including: immutability functional-first everything everywhere minimal syntax to learn some batteries included There is no real groundbreaking single feature that I think is especially notable about Baba Yaga. Instead, it mixes a bunch of familiar functional programming concepts into a hopefully cohesive and expressive combination that is orders of magnitude simpler than other such functional languages. Baba Yaga is kinda like Toki Pona but for Haskell. Basic Syntax and Data Types The syntax aims for visual clarity with minimal punctuation. Over the last few years, I’ve really fallen for typed languages,...
