- The title of this article is not correct because of technical limitations. The correct title is actually :).
:) is an esolang created by User:Martsadas that only uses smileys
Valid tokens are :), :P, :], :>, :D, and :O.
Valid instructions:
All instructions start with an instruction modification parameter kinda like Whitespace.
Instruction modification parameters
| :) |
I/O
|
| :P |
Cells
|
| :] |
Arithmetic
|
| :> |
Repeat same IMP as last instruction
|
| :D |
Flow control

Instruction arguments are separated by
:>.
Lines are separated by
:O.
I/O
| :) |
:) [c] |
Prints cell [c] as an ASCII character
|
| :P |
:P [c] |
Prints cell [c] as a number
|
| :] |
:] [c] |
Asks the user to input a number and stores it into cell [c]
|
| :> |
:> [c] |
Prints constant [c] as an ASCII character
|
| :D |
:D [c] |
Asks the user to input a character and stores its ASCII value into cell [c]
|
:) stores variables in cells.
Cells
| :) |
:) [c] :> [n] |
Sets cell [c] to value [n]
|
| :P |
:P [a] :> [b] |
Sets cell [a] to the value of cell [b]
|
| :] |
:] |
Moves the cell pointer left
|
| :> |
:> |
Moves the cell pointer right
|
| :D |
:D [c] |
Sets cell [c] to the cell pointer's position
|
Arithmetic
| :) |
:) [a] :> [b] :> [c] |
Sets cell [c] to cell [a] + cell [b]
|
| :P |
:P [a] :> [b] :> [c] |
Sets cell [c] to cell [a] - cell [b]
|
| :] |
:] [a] :> [b] :> [c] |
Sets cell [c] to cell [a] * cell [b]
|
| :> |
:> [a] :> [b] :> [c] |
Sets cell [c] to cell [a] / cell [b]
|
| :D |
:D [a] :> [b] :> [c] |
Sets cell [c] to cell [a] % cell [b]
|
Flow control
| :) |
:) [n] |
Creates a new label [n]
|
| :P |
:P [n] |
Goes to label [n]
|
| :] |
:] [n] :> [a] :> [b] |
Goes to label [n] if cell [a] and cell [b] are equal
|
| :> |
:> [n] :> [a] :> [b] |
Goes to label [n] if cell [a] is greater than cell [b]
|
| :D |
:D |
Halts the program

Numbers:
Numbers in :) are stored in base 4.
Notes:
The cell pointer
- You can access the cell that the cell pointer points to by accessing cell 0.
- The cell pointer can't move left when it's at 1.
Comments
You can write a comment by using ; which will make a single-line comment.

Truth-machine:
:) :] :D :O ; Get input
:P :) :P :> :P :O ; Set another cell to 1
:D :) :] :O ; Make a new label
:) :P :D :O ; Print the input
:D :] :] :> :D :> :P :O ; Jump to the label if the input is equal to 1
:D :D :O ; Halt the program
