Qadi

Introduction

Qadi (/qədi/) is a language made by User:Biscat111 in 2026 due to a perceived lack of queue based languages.

It is most likely turing complete, and the original creator is planning to write a brainfuck interpreter in Qadi.

Description

Qadi is a queue-based language with 7 instructions.

Command	Description
.	Adds a 0 to the end of the queue.
+	Increment the value on the front of the queue.
-	Decrement the value on the front of the queue, the value is allowed to go negative.
r	Copy the value on the front of the queue to the back of the queue, then pop the front value.
i	Makes you input a number or a character, depending on if the following character in the code is a "c"
o	Outputs a number or a character, depending on if the following character in the code is a "c"
s	Always followed by a number N in the code. If the front value of the queue is not 0, jump to the Nth character.

Any other characters are noops.
