19 is a joke esolang by user:raiseafloppafan7741 in 2026 to make specific Esofish implementors want him dead.

Overview

The program is a program in Unlambda which outputs a program in Lua which then prints a program in Python 3 which then prints a program in C++ which then prints out a program in Java which then prints out a program in COBOL which then prints out a program in Ruby which then prints out a program in Uiua which then prints out LLVM IR to be compiled by LLVM and outputs a JavaScript program which outputs a Crazy J program which outputs a Catgirl Rainfart program which outputs a Zig program which outputs another Zig program which outputs a brainfuck program which outputs a Malbolge Unshackled program which then outputs a PHP program which then outputs another Lua program which then outputs a Scratch ZIP file and the contents of the global list my_list are joined into lines which are then executed as another C++ program which then outputs a Rebol program which then outputs a program in C3 which then outputs a program in HolyC which then outputs a program in JavaScript. Between each link, the generated programs are split into 256-bit chunks which are then incremented by the generating program's SHA-256 hash. Then, the final program is then reversed before it is run as JavaScript.

However, the initial Unlambda program must be encoded using a directory structure in the user's file system. For example, ```sii``sii would look like:

APPLY
+-- APPLY
|   +-- APPLY
|   |   +-- s
|   |   +-- i
|   +-- i
+-- APPLY
    +-- APPLY
    |   +-- s
    |   +-- i
    +-- i

This is not in a text file, this is actually a directory structure in the user's file system.
