# marble "programming language"
Source code is ascii art that describes a marble track. Marbles carry one byte of data each and move around interacting with parts of the board. Marbles can be created and destroyed arbitrarily by the various operators.
Marbles carry one unsigned 32 bit integer each and move around interacting with tiles on the board. Source code is ascii art that describes a marble machine. Marbles can be created and destroyed arbitrarily by the various operators.
## physics
Marbles (`o`) start out moving down (unless emitted by something).

- `B` Bag: consumes marbles that move into it, and emits an empty (0) marble when powered.
- `ASMDR` Math: Add/Subtract/Multiply/Divide/Remainder of the marble on the left and the right, relative to the power direction. Outputs a marble forward if at least one input exists.
- `LG=!` Logic gates: (Less/Greater/Equal/Not Equal) compares the left and right input (both treated as 0 if absent) when powered, and powers forward if the result is true.
- `P` Print: Prints the value of the front marble when powered
- `P` Print: Prints the value of the front marble when powered, truncated to a single byte.
- `I` Input: Outputs a marble with the next byte from the program input stream, if there are any
- `0123456789` Digits: decimal digits are added to a marbles value after multiplying the marble with 10, this means that a marble passing over `123` would contain the number 123 afterwards. Digits are consumed by marbles passing over them.
