yep.

yep. is an esoteric programming language by user:raiseafloppafan7741 in 2026. It was made to try gaming the Esolang Quality Rating System with a brain-discombobulating esolang that reeks worse than a burning landfill on Uranus.

Overview

There is a staque (stack-queue hybrid, you can pop from the bottom of the stack) of signed 32-bit integers. Popping/dequeuing from an empty staque returns 0 like in Befunge.

Command	Description
KASANE TETO!!!!!!!!!	Enqueues 401.
JOHN MESMERIZER!?!??!?!?	Reads a byte of input from the user and enqueues it, or -1 if it has reached EOF.
SIX SEVEN!!!!	Enqueues 67.
analysisofvariance/raiseafloppafan7741/minicometiiww is a lazy piece of [REDACTED]	Enqueues 1. Also, it's true. That's why this command exists.
BLACK HOLE, PLEASE SAVE ME!!!!!!	Dequeues a value from the staque and discards it.
This is a rock and this is water.	Pops a number and prints it.
If you pour water on a rock, nothing happens.	Pops a number and prints it modulo 256 as a byte.
teto is a vocaloid	Halts. This is required otherwise the program loops forever.
Wheel Ooze A Hole Bunch!	Pops a number and if it is zero, skips running the next instruction.
A Better Name Than That	Dequeues a number and if it is zero, skips running the next instruction.
The landscape will be clean and pristine, free from slop for miles and miles.	Pops the top of the stack and pushes it twice.
There will be a massive slop tower in the middle where people can get their fix of slop.	Dequeues a value from the staque and enqueues it twice.
You WILL buy slop from MY slop tower and you WILL be happy.	Pops two values from the stack and pushes the second one popped, then the first one.
esomark, help me!	Dequeues a value and enqueues it.
NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!	Pops two values from the staque and pushes the difference between the second and the first value.
itsudemo i love you	Dequeues two values from the staque and enqueues the differnece between the second and the first value.
you really are an idiot	Pops a value from the staque and pushes it multiplied by negative one.
kimi ni take kiss me	Dequeues a value from the staque and enqueues it multiplied by negative one.
PEEP THIS AURA	Dequeues two values from the staque and enqueues 1 if they are equal and 0 otherwise.
Bored, going to sleep	Pops two values from the staque and enqueues 1 if they are equal and 0 otherwise.
hi~	No-op.
DAIDAIDAIDAIDAIKIRAI	Starts a while loop. Dequeues a value and if it is zero, then it jumps to the corresponding helo pkmnq
DADADADADARU	Starts a while loop. Pops a value and if it is zero, then it jumps to the corresponding helo pkmnq
helo pkmnq	Ends a while loop. This jumps to the matching loop starter.
uwu~ :3	Dequeues a number and prints it.
i-it's not like i like you or anything!	Dequeues a number and prints it modulo 256 as a byte.
fine...	Pops a number and if it is 0, pushes 1, else 0.
Helo de67	Dequeues a number and if it is 0, enqueues 1, else 0.
d-do i look cute? :3	Reverses the staque. This was made to make Turing-completeness easier.

Computational class

yep. is Turing-complete as it is a queue automaton and one queue can be used to simulate an unbounded tape. However, its computational class can be more rigorously proved by translating BitBrain-R to it.

The initial 10 bits can be done with:

The landscape will be clean and pristine, free from slop for miles and miles.
The landscape will be clean and pristine, free from slop for miles and miles.
The landscape will be clean and pristine, free from slop for miles and miles.
The landscape will be clean and pristine, free from slop for miles and miles.
The landscape will be clean and pristine, free from slop for miles and miles.
The landscape will be clean and pristine, free from slop for miles and miles.
The landscape will be clean and pristine, free from slop for miles and miles.
The landscape will be clean and pristine, free from slop for miles and miles.
The landscape will be clean and pristine, free from slop for miles and miles.

BitBrain-R	yep.

The program is then terminated with teto is a vocaloid.
