Unibrain

Jump to: navigation, search

Unibrain is a joke esoteric programming language created by User:Robert de Bath. It is identical to Brainfuck, except that the instructions are changed to repetitive codes each of which are interpreted as a form of unary number. As such, it is an infinite subset of the TrivialBrainfuckSubstitution family of programming languages. Note there are 40320 related subsets where the brainfuck commands are reordered.

Commands

Brainfuck Unibrain Description
> Baa Move the pointer to the right
< BaaBaa Move the pointer to the left
+ BaaBaaBaa Increment the memory cell under the pointer
- BaaBaaBaaBaa Decrement the memory cell under the pointer
. BaaBaaBaaBaaBaa Output the character signified by the cell at the pointer
, BaaBaaBaaBaaBaaBaa Input a character and store it in the cell at the pointer
[ BaaBaaBaaBaaBaaBaaBaa Loop Start: Jump past the matching loop ending if the cell under the pointer is 0
] BaaBaaBaaBaaBaaBaaBaaBaa Loop ending: Jump back just after the matching loop start

Each of the Baa codes represents any case insensitive ASCII alphanumeric string the string must be concatenated the specified number of times (1..8) to represent a command. If it's possible to divide the string in more than one way (eg: 1, 2, 4 and 8) the largest number must be used. For unibrain the code used does not have to be the same from command to command.
