BinaryBefunge is an esoteric programming language written by Dominicentek. It's a clone of Befunge. It's like Befunge, but all the characters are represented as binary.
Instructions
This esolang has all the instructions as Befunge-93. Each binary digit is an ASCII value of the Befunge-93 command. When any character found that is not 0 or 1 will make the interpreter quit automatically without execution.
| Instruction | Description |
|---|---|
| 00101011 | Pops 2 values and adds them, then pushes the result |
| 00101101 | Pops 2 values and subtracts them, then pushes the result |
| 00101010 | Pops 2 values and multiplies them, then pushes the result |
| 00101111 | Pops 2 values and divides them, then pushes the result |
| 00100101 | Pops 2 values and modules them, then pushes the result |
| 00100001 | Pops 1 value and checks if its a 0, if yes, a 1 is pushed. Otherwise a 0 is pushed |
| 01100000 | Pops 2 values and compares them, If 2nd value is greater than 1st, it pushes a 1, otherwise it pushes a 0 |
| 00111110 | Makes the pointer move right |
| 00111100 | Makes the pointer move left |
| 01011110 | Makes the pointer move up |
| 01110110 | Makes the pointer move down |
| 00111111 | Makes the pointer move in random direction |
| 01011111 | If statement, a value is popped and checks if its a 0, if yes, the pointer moves right, otherwise it moves left |
| 01111100 | If statement, a value is popped and checks if its a 0, if yes, the pointer moves down, otherwise it moves up |
| 00100010 | Toggles string mode. Pushes any ASCII code onto the stack until the next 00100010 is reached |
| 00111010 | Duplicates the top value on the stack |
| 01011100 | Swaps the top 2 values on the stack |
| 00100100 | Pops the top value on the stack and discards it |
| 00101110 | Pops the top value of the stack and outputs it as an integer to the console. |
| 00101100 | Pops the top value of the stack and outputs it as an ASCII character to the console. |
| 00100011 | Skips the next instruction |
| 01100111 | Pops 2 values of the stack and uses it as Y and X coordinates. Then, pushes the ASCII code of the character on the playfield on these coordinates. |
| 01100111 | Pops 3 values of the stack and uses it as Y and X coordinates and an ASCII code. Then, puts the ASCII character onto the playfield on the X and Y coordinates. |
| 00100110 | Gets an integer from the user and pushes it onto the stack |
| 01111110 | Gets ASCII character from the user and pushes it onto the stack |
| 01000000 | Ends this program |
| 00110000 to 00111001 | Pushes a number onto the stack |
Any value that is not a valid instruction is ignored. As in Befunge-93, the playfield is 80x25 characters. Each row must have 80 8-bit binary digits, terminated with a new line. There also must be 25 rows.
