# Poohbear

Poohbear is a stack-based language largely inspired by Brainfuck. It has a maximum integer value of 255, and 30,000 cells. The original intention of Poohbear was to be able to send messages that would, to most, be completely indecipherable.

## Commands

Command Definition
+ Add 1 to the current cell
- Subtract 1 from the current cell
> Move the cell pointer 1 space to the right
< Move the cell pointer 1 space to the left
c "Copy" the current cell
p Paste the "copied" cell into the current cell
W While loop - While the current cell is not equal to 0
E Closing character for loops
P Output the current cell's value as ascii
N Output the current cell's value as an integer
T Multiply the current cell by 2
Q Square the current cell
U Square root the current cell's value
L Add 2 to the current cell
I Subtract 2 from the current cell
V Divide the current cell by 2
A Add the copied value to the current cell's value
B Subtract the copied value from the current cell's value
Y Multiply the current cell's value by the copied value
D Divide the current cell's value by the copied value.

## Examples

Although there are many ways to do the same thing, here are some examples. The following is a Hello World Program:

```+LTQTP>LL+TQ+P>LLT-c<APP>IIc<AP>I->+LLT+TTP<+LLTLc>BP>+LQQLLLP<<<PL+PIIIPIIIIP>>>>LLQT+P
```

There's nothing too complicated in this example. A program that outputs all printable ASCII characters:

```+LTQIIWP+E
```

This program starts at a value of 32, the first printable ASCII character. Then it increments by 1 every loop until it reaches 0 and the loop closes. A program that prints numbers from 1-255:

```+LTQII>+WN<P>+E

```

The first section stores 32, which in ASCII is a space. Then it adds one to the next cell, and goes through all the numbers until it wraps back to zero and the loop closes.

## Interpreters

An interpreter for Poohbear was written in C, which worked by rewriting the input program and converting it to its C equivalent, and then compiling and running it. That interpreter can be found here.. To run a `.pb` file, open the command prompt in the folder, and type `poohbear file.pb`.
