Falsebrain9Q+Fishload

Description

Falsebrain9Q+fishload is an ingenious combination of many esolangs: False, Brainfuck, HQ9+, Deadfish, and Underload. It has two stacks, a tape, and an accumulator. As you can see, this makes the language Turing-complete but also powerful.

Commands

False

• {<code>} - execute False code inside {}.

BF

• [] - BF loops.
• + - BF increment
• - - BF decrement
• . - BF output
• , - BF input
• < - BF move left
• > - BF move right

HQ9+

• H - print Hello, world!
• 9 - print 99 bottles of beer
• Q - perform a Quine

Deadfish

• i - increment accumulator
• d - decrement
• s - square (using Deadfish arithmetic)
• o - output accumulator

Underload

• (<code>) - execute code inside () as Underload.

Inter-language

• %<l1><l2> - transfers data between the two languages' forms of storage.
• Example: %BF pushes the value on the BF tape to the False stack.

Language codes

• F - False stack
• B - BF tape
• D - Deadfish accumulator
• U - Underload stack

Examples

Hello, world!

h

99 bottles of beer

9

Quine

q

Example

This example prints 100.

iiis%DB+%BF{$*}%FU(S)

First it forms 9 in Deadfish, then adds 1 in BF, then it squares in false, and outputs in Underload.
