For readers




Failing that, you could take a look at a random language.

Featured language

Thue is an esoteric programming language based around the idea of a "semi-Thue system": a system which specifies strings that can be rewritten to certain other strings; a program is simply a list of search strings, and possible replacements for them. As a nondeterministic language, a program has the potential to halt if there is some way to reach an end state via applying replacements, even if rules such as "always apply the first replacement" would lead to an infinite loop. No data storage is necessary, apart from a single string that holds the entire state of the running program, although this often causes programs to run slowly due to delays in communicating information from one part of the string to another.

For creators

If you've just created a language, you can create an article for it by typing its name into the search box, assuming the name is not already taken, but be sure to take a look at the help guide first. Then you should add it to the language list (or the joke language list, as appropriate).


Otherwise, you could help out with a work in progress.


Since April 2005, 3,422 articles have been created by 87,358 edits, including 2,768 esoteric languages. There are 7,163 registered users, but most of them are spambots.
