BDAMD: Basic Demonic Asinine Multi-Dimensional
Home site, by its creator: descriptions, code samples, download.
bogusforth
By Antonio Maschio. An obfuscated language, powerful, quite complete, based on forth, "false" (by W. van Oortmerssen) and "TRUE" (by Dewi).
Cat's Eye Technologies
Specifications, implementations, sample source code collections for several strange languages, comments on obfuscated language taxonomy and on several far-out coding practices, mail list, links to many related sites.
Comment Programming Language
An open-source language for writing comments.
DM's Esoteric Programming Languages
D. Morgan-Mar esoteric languages Chef, Haifu, Ook!, Piet, Whenever. Links.
Esoteric Non-existent Standards Institute
"Institute" for the standardization of unstandardized standardizable things, mostly esoteric languages and extensions to them.
Esoteric Programming Languages Ring
An organisation started to spread insanity and weird programming paradigms among the masses.
esoteric.sange.fi
Collection of esoteric programming language implementations, examples, and related files.
False
Programming language with two main goals: confusing everyone with an obfuscated syntax, and designing as powerful a language as possible with a tiny implementation: this compiler executable is only 1024 bytes, written in pure 68000 assembler.
GAMIZETA
A superset of the BrainFuck programming language.
Iota and Jot
Iota is an unambiguous Turing-complete language with just two symbols, heavily utilizing the lambda calculus. Jot is an offspring of Iota that provides, among others, a particularly elegant Goedel numbering. This page also contains a four-line Iota implementation and a five-line Jot implementation in Scheme, and Javascript interpreters for the two languages.
l33t
An esoteric language inspired by BF and Beatnik which allows l33t h4xX0r5 to write programs in their native dialect.
Lesser-Known Programming Languages
Brief introductions to LITHP, C-, FIFTH, and other programming languages that have been overdue for a long time.
malbolge: "hello world"
The very first Malbolge program to appear, how it was crafted (by a genetic algorithm program) and similar things.
Malbolge: Programming from Hell
Specifically designed to be extremely difficult to program in.
nouse
A language in which the IP (instruction pointer) varies depending on the current stack size.
npiet
An interpreter for the piet programming language. In this language the programs are pictures, build out of 18 colors and black and white - this is about the real "art of programming".
Orthogonal
A programming language in which program flow can go sideways. Closely related to Befunge. Tutorial, reference, sample source code, Public Domain implementation available.
P-nand-Q
Home of esoteric programming languages such as Java2K, Smith#, Sorted!, [], Esogotschi and the Great Python Language Zoo. Also heavy on the code obfuscation front.
PingPong
An interpreted two dimensional language based on "Befunge". It is not intended to create useful programs but just to experiment with an unusual programming concept.
Programming in Malbolge
Introduction to Malbolge programming. Also propose modificatins of Malbolge for making programming in it more worse.
Q-BAL Programming Language
A queue based programming language. It's not designed to be useful, just fun.
Shakespeare
A language with beautiful source code that resembled Shakespeare plays.
The Unlambda Programming Language
Minimalistic functional language based on the Lambda calculus but lacking the Lambda operator. Tutorial, reference, GPLed interpreters available.
Turing Tarpit
Directory of sites dealing with obfuscated programming languages.
Waduzitdo
Turing incomplete programming language written by a guy named Larry, who's friends always asked him about his new PC: "What does it do?" Works via 2 registers: accumulator and match flag which holds one value (T or F).
Weird Programming Languages
Yet another list of obfuscated programming languages.
Whitespace
Any non whitespace characters are ignored; only spaces, tabs and newlines are considered syntax.
XS - XML Programming Language
A toy obfuscated programming language from the brain of Mark Carter. Harness the power of XML, by using it as a programming language. Comes with compiler and example code.
ZT
The esoteric programming language. Documentation, interpreter, and example programs.
