Ni is an esoteric programming language influenced by brainfuck. The name Ni comes from Nicaragua. Created by User:DeybisMelendez.
Language Overview
Like brainfuck, Ni operates on a tape containing cells, cells can store 64-bit integers. The cells are pointed by a head, the head can move from left to right or jump to a cell directly. There is also a clipboard where you can store data from one cell and insert any other.
Commands
| Command | Description |
|---|---|
| > | Move the head to the right |
| < | Move the head to the left |
| + | Increment the targeted cell |
| - | Decrement the targeted cell |
| @ | Reads the first character, converts it to its ASCII number and stores it in the pointed cell |
| . | Print the number stored in the targeted cell |
| ! | Print the ASCII equivalent of the number stored in the pointed cell |
| # | Set a hexadecimal number in the pointed cell |
| ? | Copy the number of the pointed cell |
| = | Stores the copied number in the pointed cell |
| * | Converts the number of the pointed cell to 0 |
| $ | Moves the spindle to the cell indicated with a hexadecimal number |
| [] | (While) Loop that continues execution if the pointed cell is not equal to 0 |
| {} | (For) Loop that executes the instructions the number of times that the memory of the pointed cell indicates |
| () | (if) Executes the set of instructions if the pointed number is equal to the clipboard |
| / | Ignore the rest of the line |
Examples
Hello World!
#48!#65!#6c!!#6f!#20!#57!#6f!#72!#6c!#64!#21!#a!
Cat program
+[@!#a!]
Truth-machine
@>#30[<->-]<.[.]
Fibonacci
#a>>+.<<!>>>>#1f{<<?>=<<[>>+<<-]>?<=>>?<=.<<!>>>>}
Factorial
#0 /Insert the number to calc, #0 prints 1, #9 prints 362880, etc.
(+.*)[?>=-[-<{>{<+>}<}>]<.*]
Computational class
Ni is Turing-complete, as ><+-@![] correspond directly to brainfuck's ><+-,.[].
