24 alternatives to Lambduck, a Functional Programming Brainfuck
What if Brainfuck was less like C and more like Scheme? The interpreter implemetation is pretty bad. It's not very fast, it's not very good, and it's probably not very correct. But maybe there's some vaguely interesting programs you could write with it! For example, the Y combinator: λf. (λx. f (x x)) (λx. f (x x)) is written as: \` \`1 `0 0 \`1 `0 0
Lambduck is an esoteric programming language that combines Brainfuck's minimalist design with functional programming concepts inspired by Scheme. It allows users to write programs using lambda calculus notation, such… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

Hi friends, I started casually working on scrapscript in 2015. I built a few compilers over the years to test out various ideas/implementations, and I think I'm finally happy with the overall design. The code is not public yet. Email me at [email protected] if you're interested in joining the core team later this year. Let me know if you have any questions or feedback :)

Hi all! I'm going into my freshman year, and figured that the best way to prepare for the intro to programming Racket course would be to implement my own garbage-collected, dynamically typed, functional programming language in C ;) Anyways... here's the repo: https://github.com/liam-ilan/crumb I started learning C over the summer, so I still have a whole lot to learn... Any feedback would be greatly appreciated! :D

This is a hobby project of mine that I started a few years ago to learn about programming language implementation. It was created 95% without AI, although a few recent commits include code from Gemini CLI. I started out following Crafting Interpreters, but gradually branched off that until I had almost nothing left in common. Tech stack: Rust, Cranelift (JIT compilation), LALRPOP (parser). Original title: "A small programming language where everything is a value" (edited based on comments)

i made an esoteric programming language which i call spellscript. every program is a "spell" written in a "grimoire," and you have to use keywords like summon, enchant, inscribe, and conjure. it's literally read like a spellbook because the syntax consists of all natural language, and newlines are optional. your code can now be an essay, like everybody wants! for example, if you want to print something, you'd write: `begin the grimoire. inscribe whispers of "hello, world!". close the grimoire.` it has variables, dynamic typing, arrays, functions, conditionals, loops, string manipulation,…

I've been spending some time coding fp. It is a programming language heavily inspired by the language John Backus described in his 1977 Turing Award lecture. There's plenty of examples in the projects github repository for the interested!

Greetings! A 2.5 weekends project to teach myself newer Python features (>= 3.10). Conditions are written as Lambda expressions that annotate parameters and return types, and coexist with type annotations. Symbols to share values between conditions are also supported to a limited extend.

Hi HN, author here. Happy to answer any questions. I had an itch to make a lisp like language that was a thin layer on top JavaScript. Something that could leverage the thriving ecosystem that exists around JavaScript. It's brittle, hot off the oven. Besides being a fan of parenthesis, I think macros fill in a gap that the JavaScript ecosystem today fills in with one-off compilers, bundler plugins and such. Macros can't do everything, but for example I think they have the potential to enable things like JSX, Solid and Svelte style libraries. Take the tour to get a feel for what it can do and…
