Hey HN! Fun to see this project from my college years on HN again. To clear my name, I <i>have</i> actually written other languages that are arguably more useful, like Oak [0] which I used to build a bunch of personal software infrastructure [1] including my current daily-driver apps for notes, longform writing, a Twitter client, a personal search engine, and a few other knickknacks.<p>I find building little toy interpreters and programming languages fantastically fulfilling, creatively energizing, and a really fun way to learn how such a common element of our work that's often a black box functions inside. I've written before about how to get started [2] with these kinds of little toy programming language projects if you're curious to dive in.<p>[0] <a href="https://oaklang.org/" rel="nofollow">https://oaklang.org/</a><p>[1] <a href="https://github.com/topics/oaklang">https://github.com/topics/oaklang</a><p>[2] <a href="https://thesephist.com/posts/pl/" rel="nofollow">https://thesephist.com/posts/pl/</a>
