Code examples in 39 esoteric programming languages

Someone as a joke, someone to prove the existence or disprove the hypothesis, someone to warm up the brain (traveling on the surface of a Klein bottle or in four-dimensional space), but hundreds of people have created "esoteric" programming languages. I have flipped through about 150 such languages ​​and can never be the same again.



“Argh!”, “Oof!”, “2-ill”, “Nhohnhehr”, “Noit o 'mnain gelb”, “DZZZZ”, “Ypsilax”, “YABALL”, fuckfuck are spells , poetry is just the names ... under katom - examples of code in the most vigorous programming languages.

The rabbit hole is deep.

INTERCAL (turing-full)

Don Woods and Jim Lyon

One of the oldest esoteric programming languages. According to the creators, its name means “Programming language with an unprovable abbreviation” (English Compiler Language With No Pronounceable Acronym). The language was created in 1972 by students Don Woods and James M. Lyon as a parody of existing programming languages ​​and mind gymnastics.

Hello, world

Each program command can be given the probability with which it will be executed when the program is started. In addition, there are commands that block the execution of subsequent commands of a certain type or change variables.

Brainfuck (turing-full)

One of the most famous esoteric programming languages, invented by Urban Muller (German Urban Müller) in 1993.

Hello, world!

Befunge

Stack esoteric programming language. It is considered two-dimensional, since the program on Befunge is recorded in a table with stitched edges (torus), along which the interpreter moves in different directions, executing commands located in its cells. Written by Chris Press in 1993. According to the author, his goal was to develop a language that is as difficult to compile as possible. The difficulty is provided by the p and g commands modifying the program text.

Hello, world!

Malbolge

The language is designed to be as difficult as possible to write programs. Got its name from Malebolge, Dante's eighth circle of hell.

Piet

The Piet language uses multi-colored images as programs. The program on Piet looks like a post-pictorial abstraction. Piet got its name from the name of the Dutch artist Piet Mondrian.

1L_a (expected to be Turing-complete, but this has not been proven)

Program to print the character "A"


The original of the program at the left, on the right - the integrated version

2L (turing-full)

A simple cycle that gets 9 by multiplying 5 by 2 and subtracting 1

4DL

In 4DL, a four-dimensional grid is used to represent the program, and the directions for its implementation, respectively, are 8.

The program that prints the sum of the numbers from the input line:



The execution path of the above program in 4-dimensional space:

Whitespace

Whitespace (English space) - esoteric programming language created by E. Brady and C. Morris. Its essential difference is that only unprintable characters are used for control structures, namely: space, line feed and tabulation. An interesting consequence of this fact is that the Whitespace program text can be “hidden” inside the source code of another program.

LOLCODE

An esoteric programming language inspired by the Internet meme of lolcat. There is a specification of this language and there are several working interpreters and compilers of this language. LOLCODE is a Turing complete language.

Chef

Esoteric programming language developed by David Morgan-Mar, the program which is similar to culinary recipes. Each program in the language consists of a name, a list of variables and their values, a list of instructions. Variables can only be called basic food names. The stack in which the values ​​of variables are placed is called English. mixing bowl (“mixing bowl”), and operations for manipulating variables - mix (“mix”), stir (“shake”) and so on.
