#esoteric programming language

[lavenderhorns]

Every now and then I remember that Malbolge exists and I get to spend the better part of an hour cry-laughing at the world’s worst programming language

already starting off strong, but it gets worse

Wow! Sounds easy and intuitive to use! What’s the “crazy operation” you ask? We’ll get to that later. For now let’s see what a program in this language looks like :)

Thanks! I hate it!

it’s so difficult to work with that the first program was written by another brute force search program

mmmmm delicious base-3 arithmetic, what could go wrong? (For reference, that means this program forgoes the usual “0/1″ values of binary code in favor of a much more fun “0/1/2″ set of values)

ah.

Here’s how the language actually figures out what to do. It’s got 8 “simple” commands that can be executed easily by *checks notes* running the code itself through the modulo operation and taking the result.

As a bonus, on top of all that every single character in your code will now alter what every single other character does. So I hope you’re alright with cracking a cipher every time you add a new letter to your program!

oh god oh fuck.

behold, Malbolge’s primary arithmetic operation and what you’ll be using for most of your math while programming with it :)

This looks specifically designed to be the least logical math operation you could make, and knowing what the rest of Malbolge is I’d wager that’s precisely what happened. I never want to ever use this and it’s my favorite thing I’ve ever seen.

https://en.wikipedia.org/wiki/Malbolge

Anyways here’s the wiki page if you wanna read through it more deeply, I’m gonna sit here holding in my laughter staring at the hello world program again.

My Esoteric Programming Language Synopsis

Been looking into esoteric programming languages, or programming languages whose purpose is NOT to make a programmer's life easier, but rather to be weird and often confusing. Here are my reviews:

<>< (Fish): This language revolves around the moving a pointer around the program itself, which is read as a 2 dimensional grid of characters. The pointer moves to the right by default, but you can change its direction with the arrow-looking characters (<,>,^,v). You can also reflect the instruction pointer with the mirror-looking characters (|,_,/,\\), which reflect the arrow the direction that makes sense based on what way it is going and the geometry of the characters. On top of this, the language is stack-based. For those who don't recall the first few pages of Homestuck, a stack is a data structure that stores a list of values like an array, except the only accessible datum in the stack is the most recently entered one. Programmers have no business using stacks in the year 2023. Other neat details include the trampoline instruction (!) which jumps over a spot in the grid, and because you need to use a stack, to print a value from code, you need to write it in the code backwards. Also when you get an error, the compiler says "Something smells fishy..." Difficulty 3/10

Brainfuck: Brainfuck was made by a man trying to make the smallest programming language compiler he could. The program instructions rely on an arbitrarily large 1 dimensional array of numbers. Brainfuck has 8 single-character commands, and all other characters are treated as comments. This is a brainfuck program to write "Hello World":

+[-->-[>>+>-----<<]<--<---]>-.>>>+.>>..+++[.>]<<<<.+++.------.<<-.>>>>+.[<->-]<-.>

Difficulty 9/10

Hexagony: Like <><, Hexagony works by sending a pointer along the program, treating it like a grid of characters. The difference is that Hexagony programs are on a hexagonal grid. This is Hello World in Hexagony:

Difficulty 8/10 (I cannot wrap my head around this one)

INTERCAL: Compiler Language With No Pronounceable Acronym, or INTERCAL, was one of the first esoteric programming languages, created in 1972. The language was designed to make common operations needlessly difficult, while adding keywords for other operations to make the whole thing unpleasant to look at. There is a keyword “PLEASE” that doesn’t do anything, although if you don’t include enough “PLEASE” commands, the compiler will give an error stating your program is not polite enough. Unlike most of the programming languages on this list, INTERCAL is too slow when compiled to be used practically. In 1992 a journalist tested the speed of Intercal against C. In C, it took less than a second to compute all the prime numbers up to 65536. In INTERCAL, it took over 17 hours. Difficulty: 8/10 LOLCODE: The syntax of LOLCODE is inspired by “lolspeak,” the English dialect of lolcat captions. Every LOLCODE program begins with “HAI” and ends with “KTHXBYE”. To import library STDIO, use the command “CAN HAZ STDIO?” The underlying structure of LOLCODE is actually fairly standard, which makes this esolang pretty accessible.

Difficulty: 1/10

Malbolge: How do you print “Hello, World” in Malbolge?

(=<`#9]~6ZY327Uv4-QsqpMn&+Ij"'E%e{Ab~w=_:]Kw%o44Uqp0/Q?xNvL:`H%c#DD2^WV>gY;dts76qKJImZkj

Malbolge was designed to be the most difficult programming language in existence. The language determines which of the eight available instructions to execute by adding the current instruction to the current instruction’s index in memory, modulo 94. There are no arithmetic operators except for the *crazy operator*, a Malbolge original that takes two numbers in their ternary form and determines the result digit by digit using an unintuitive table. The crazy operator is not commutative, and is your only arithmetic operation. Whenever an instruction is executed, it is encrypted so that it will not do the same thing next time. Due to the complexity of Malbolge, a turing complete version does not currently exist, limited by the size of programs allowable.

Difficulty: 20/10

esolangs in Minecraft

I've been playing around with implementing esoteric programming languages as Minecraft data packs

for a bit I've had the idea of implementing BackFlip, a 2d language which is vaguely similar to the Langton's Ant cellular automaton and based on arrows and mirrors, the two of which conveniently resemble magenta and pink glazed terracotta

in figuring out how best to do output (I used tellraw with the "interpret" option for an NBT list, though I've since discovered this doesn't necessarily work for broader character sets than BackFlip's), I discovered that the new 1.19.4 "string" option for the /data command allows taking substrings; this (and the /data command in general) gave me the idea of implementing a more complex text-based language, which could be written in a book and quill

as a very basic proof-of-concept of text processing, I made an interpreter for the joke language Deadfish (which just has commands for incrementing, decrementing, squaring, and outputting a counter)

I was able to do it with a single function file, which made it convenient to add to the esolangs wiki page for Deadfish

finally, as a more complete example, I made an interpreter for the popular esolang brainfuck, with the program and input being read from books

unfortunately I used the same output method that I did for BackFlip, which it turns out doesn't work with the double-quote character, so I may have to make a fix sometime here..... (EDIT: it's now fixed -- somehow I had missed the very convenient option of selecting every item of the NBT list and setting the separator to empty string)

in any case though the data packs I've made so far can be found on GitHub

another esolang I've thought in the past about implementing in Minecraft is Piet, since it's pixel-based and that translates fairly well to Minecraft blocks; the main challenge is figuring out how to efficiently parse and represent the program, since NBT lists can't be indexed by variables and I might want to avoid creating an entity for every pixel? (though IDK maybe marker entities wouldn't be an issue for performance)

Masku reference (Brainf*** derivative using Maskutchew conlang)

Yes, this "instruction set" is meant to be both usable for humans, computers and anything in between (like animals and weirder lifeforms) for actual programming. Don't forget to format your statements and structures using parentheses, similarly to LISP.

OPERATIONS

Basic instructions

INCREMENT= 'INKER'

DECREMENT= 'DEKER'

PREVIOUS_CELL= 'LOVI'

NEXT_CELL= 'JOST'

NOT= 'ÑIA'

AND= 'UDER'

OR= 'UKU'

XOR= 'UFE'

BITWISE_OPERATOR= 'MELE'

JUMP_EQUAL= 'TEN'

JUMP_GREATER_THAN= 'KEZ'

JUMP_LESSER_THAN= 'REN'

JUMP_ZERO= 'NIL'

JUMP_NEGATIVE= 'MAT'

READ= 'LIREC'

WRITE= 'SCHKERI'

LOAD= 'AGAL'

STORE= 'ENRE'

WAIT= 'FELOH'

REMARK= 'DIS'

REFER= 'MARO'

RANDOM= 'ALEAS'

LABEL= 'LAB'

'MASKU' comments

'WAIT' is a mixture of wait, noop, halt and return in various programming languages. 'REMARK' is a comment indicator so the text coming after is ignored until the next newline. 'REFER' is like a import statement in most programming languages altrough it can also be used to suggest facultative code sets. 'LABEL' is a way to both ease programming (calling functions for example) and identifying segments within the code which should be executed on which priority level (defining different parts of a argument)

'MASKU' example programs

writing "Hello, World!" in the Maskutchew conlang, program

( (LAB 'eleo uwelt') (DIS 'libral.m') (AGAL den "Eleo, Uwelt!" ) (SCHKERI den) )

Eleo, Uwelt!

quine program

( (LAB 'reken') (DIS 'libral.m') (AGAL das reken.m -lr) (SCHKERI das) )

( (LAB 'reken') (DIS 'libral.m') (AGAL das reken.m -lr) (SCHKERI das) )

cat program

( (LAB 'schate') (DIS 'libral.m') (DIS 'jeks-ynta.m') (LIREC kse) (SCHKERI kse) )
