Esofish
- This language is a derivative of Deadfish.
by User:Fffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff
Deadfish with one extra instruction: r.
r runs the remainder of the program as the esolang named as the number the accumulator holds. If there are multiple esolangs with the same name, it is implementation-defined which esolang r runs.
For example (in a suitable implementation),
iissdr`Hello, World!`
runs the code `Hello, World!` as a 15 program, so it prints Hello, World!.
Computational class
If an implementation chooses, it can be Turing-complete because it can run 35, which is Turing-complete. However, as the 6 page lists a constant language for every number, it is possible that an implementation can choose to implement exclusively these, which would make the language total instead.
Interpreter
- Common Lisp implementation of the Esofish programming language, supporting 15 and 35.
