This category is for languages deliberately designed to be often unusable, unimplementable, or both. The stress is on "deliberately". A language that is unsuitable for actual programming not by intention but merely (1) due to its inventor's ineptitude, or (2) due to lack of industry support or acceptance by the computer science community, is not obfuscated. Thus this category does not list ... [MORE] Befunge@ (11) Brainfuck@ (14) Intercal@ (16) 1. BDAMD: Basic Demonic Asinine Multi-Dimensional - Home site, by its creator: descriptions, code samples, download. 2. Blank - Strange Befunge-descendant language. 3. bogusforth - Obfuscated language, powerful, quite complete, unmaintained, based on forth, "false" (by W. van Oortmerssen), and "TRUE" (by Dewi). By Antonio Maschio. 4. Comment Programming Language - An open-source language for writing comments. 5. Esoteric Non-existent Standards Institute - "Institute" for the standardization of unstandardized standardizable things, mostly esoteric languages and extensions to them. 6. Esoteric Programming Languages Ring - An organisation started to spread insanity and weird programming paradigms among the masses. 7. 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. 8. Iota, Jot, Zot - Iota is unambiguous Turing complete language with only 2 symbols, heavily uses lambda calculus. Jot is Iota variant with elegant Goedel numbering. Also: 4 line Iota implementation, 5 line Jot implementation in Scheme, JavaScript interpreters for both languages. 9. malbolge: "hello world" - The very first Malbolge program to appear, how it was crafted (by a genetic algorithm program) and similar things. 10. nouse - A language in which the IP (instruction pointer) varies depending on the current stack size. 11. 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". 12. Orthogonal - A programming language in which program flow can go sideways. Closely related to Befunge. Tutorial, reference, sample source code, Public Domain implementation available. 13. Q-BAL Programming Language - A queue based programming language. It's not designed to be useful, just fun. 14. Shakespeare - A language with beautiful source code that resembled Shakespeare plays. 15. The Unlambda Programming Language - Minimalistic functional language based on the Lambda calculus but lacking the Lambda operator. Tutorial, reference, GPLed interpreters available. 16. Turing Tarpit - Directory of sites dealing with obfuscated programming languages. 17. 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). 18. Weird Programming Languages - Yet another list of obfuscated programming languages. 19. Whitespace - Any non whitespace characters are ignored; only spaces, tabs and newlines are considered syntax. 20. XS: XML-based Obfuscated Programming Language - Toy language. Harness the power of XML, by using it as a programming language. Compiler, sample code; interesting speculations on language design. By Mark Carter. 21. ZT - The esoteric programming language. Documentation, interpreter, and example programs. 22. DM's Esoteric Programming Languages - D. Morgan-Mar esoteric languages Chef, Haifu, Ook!, Piet, Whenever. Links. 23. esoteric.sange.fi - Collection of esoteric programming language implementations, examples, and related files. 24. l33t - An esoteric language inspired by BF and Beatnik which allows l33t h4xX0r5 to write programs in their native dialect. 25. Malbolge: Programming from Hell - Specifically designed to be extremely difficult to program in. 26. Owl - Obfuscated Weird Language: character-based language interpreter written in C, in the style of False. By Antonio Maschio. 27. 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. 28. Programming in Malbolge - Introduction to Malbolge programming. Also propose modificatins of Malbolge for making programming in it more worse.
