BigBrain

BigBrain is a brainfuck remake by user k written in Lua. (Github Page)

This is not an extension, as a lot of stuff is different.

Differences

   Every byte is set to one at the beginning.
   Bytes can go as high or as low as you need
   There are 2 lanes : a processing lane and a graphics lane (both work the same, but those are their intended purposes and official names.)

All the different Commands BigBrain Has (Bytes = Cells) :

Commands

Symbol	Description	Category
+	Sets the currently selected byte's value to the sum of the next byte's value and itself.	Operations
-	Sets the currently selected byte's value to the difference between itself and the next byte's value.	Operations
*	Sets the currently selected byte's value to the product of the next byte's value and itself.	Operations
/	Sets the currently selected byte's value to the quotient of the next byte's value and itself.	Operations
=	Sets the currently selected byte's value to the next byte's value.	Operations
^	Raises the current byte's value by the next byte's value. (As in current byte to the power of the next byte)	Operations
:	Sets the currently selected byte's value to the root of itself by the next byte's value.	Operations
$	Sets the next byte's value to 1.	Operations
_	Sets the currently selected byte's value to itself concatinated with the next byte.	Operations
!	Swaps the current byte's value and the byte to the right's value	Movement
?	Swaps the current byte's value and the byte to the left's value	Movement
>	Moves the pointer 1 byte to the right	Movement
<	Moves the pointer 1 byte to the left	Movement
{	If the current byte's value is 1, go to the corresponding }	Flow Control
}	If the current byte's value is not 1, go to its corresponding {	Flow Control
[	If the current byte's value is equal to zero, go to the corresponding ]	Flow Control
]	If the current byte's value is not equal to zero, go to its corresponding [	Flow Control
(	If the current byte's value is equal to the next byte's value, go to its corresponding )	Flow Control
)	If the current byte's value is not equal to the next byte's value, go to its corresponding (	Flow Control
~	Any condition after this will be inverted, this effect can be reversed by adding another ~ symbol.	Miscellaneous
&	Sets the pointer back to the first byte.	Miscellaneous
;	Gets an input but instead of getting its ascii code, it gets it as a number. Ex. "1" is inputted, the current byte is set to 1	Miscellaneous
'	Prints the number stored in the current byte.	Miscellaneous
.	Prints the ascii character whose ascii value corresponds to the number in the current byte.	Miscellaneous
,	Gets an input's ascii code.	Miscellaneous
#	Sets the current byte's value to its index.	Miscellaneous
"	Switches which tape the pointer is currently on.	Miscellaneous
%	Sets the current cell's value to the cell with the same index on the opposite tape.	Miscellaneous

Examples

"Hello, World!" printed using a simple algorithm :

++++++>+<_$.!$>-<_$_$.!$>-<_$>+++++++<_$..!$_$_$.!$+++>+++<_$.!$++>+<_$.!$_$>++++++++<_$.!$_$_$.!$_$>+++<_$.!$>-<_$>+++++++<_$.!$>-<_$>-<_$.!$++>++<_$.!$

"Hello, world!" printed using a human brain :

++++++>+<_.!$++++++++_.+++++++..+++.!$+!=*!=_.---.*--$-.>+<----.+$+.>+<---.----.!$!*****$+.

Cat Program :

+(,.)

Move Value :

!>! this moves the current value two cells to the right while keeping the two other values intact.
