Fingerfuck is a poor quality esoteric programming language inspired by QO and Brainfuck, made by EvilRodentOfEvil

Language overview

Fingerfuck has two stacks—handA for integers and handB for ASCII characters—and a two-cell fingers tape (cell 0 integer, cell 1 ASCII) that a pointer can reference and manipulate. Values are popped off the front of the stack, but are pushed onto the back

Commands

Command	Description
/	pop handA, push handA
\	Move to the next memory cell
(	Move to the previous memory cell
)	Add 1 to the current memory cell
:	Subtract 1 from the current memory cell
;	Jump to execution index at E with a length of N
$	If current memory cell equals to E with a length of N, jump to execution index at I with a length of B
&	If current memory cell is not equal to E with a length of N, jump to execution index at I with a length of B
~	Print character with code equal to the current memory cell value to console
.	Write console input into the current memory cell
,	set pointer to input
+	increment pointer
-	decrement pointer
"	swaps between code and label mode
^"LABEL"	starts a goto with the provided label
v"LABEL"	goes to the goto with the provided label
{	sets the pointer to one if the top two values of handA are equal and zero if not, pops top two values
}	sets the pointer to one if the top two values of handB are equal and zero if not, pops top two values
[	jump past the matching "]" if the cell under the pointer is 0
]	jump back to the matching "[" if the cell under the pointer is nonzero
'	swaps between code and comment mode
a-z A-Z !?	pushes char onto the hand associated with the current finger

Examples

Hello, World!

This program prints out the words Hello World!:

~                         'switches pointer to middle'
H;e;l;l;o;!-;W;o;r;l;d;!;  'pushes Hello World! to handB'
&.&.&.&.&.&.&.&.&.&.&.&.  'prints Hello World!'
