# 2bcmc

2-bit "golfing" language for [Redwolf Programs' Chat Mini Challenge](https://chat.stackexchange.com/transcript/message/59389303#59389303):

## Documentation

2bcmc is a stack-based language, and its commands operate on a stack of integers.

If a command pops from an empty stack, an integer is instead read from STDIN.

After the program finishes, the stack is printed, separated by newlines.

There are four three commands:

- `=`: load integer literal

- `*`: repeat + eval

- `-`: subtract

- (there will be a fourth command, but there isn't yet)

Line feeds and spaces are ignored. All other characters are invalid.

### Load Integer Literal

This keeps reading commands until it finds another `=`, decodes those commands as a base-3 integer, and pushes the

result to the stack.

### Repeat + Eval

- pop a value from the stack, call it `p`

- decode `p` in bijective base 4, to an array of commands forming a `2bcmc` program

- pop another value from the stack (underneath `p`), call it `n`

- `n` times: execute that decoded program

If `n` is negative, the program is executed exactly once. If it is zero, the program is not executed.

### Subtract

This pops two values from the stack, subtracts them, and pushes the result.

Note the operation's order: if the top of the stack is `a` and the value underneath is `b`, then the result is **`a - b`**.
