Fruit

Fruit is esoteric programming language that uses fruits names as commands

Commands

Command	Description
Apple	Increment
Banana	Decrement
Watermelon	Output the accumulator as ASCII
Melon	Output the accumulator as number
Durian	Halt
Cherry	Quine
Kiwi	Hello, World!
Limon	Squaring
|	delimiter

Fruit ignores case, so you can write ApPLe, etc.

Interpreter

Python

code = input().lower()
tokens = code.split("|")
acc = 0
for token in tokens:
    if token=="apple":acc+=1
    elif token=="banana":acc-=1
    elif token=="watermelon":print(chr(acc % 256), end="")
    elif token=="melon":print(acc, end="")
    elif token=="durian":break
    elif token=="cherry":print(code)
    elif token=="kiwi":print("Hello, world!")
    elif token=="limon":acc*=acc
