Command Reference

All commands are case-insensitive.

Command Parsing is implemented with FParsec.

This allows for reporting of more advanced parse errors and suggestions:

> Place 1,
"Error in Ln: 1 Col: 10
Place 1,
         ^
Note: The error occurred at the end of the input stream.
Expecting: integer number (32-bit, signed)
"

Invariants

1. The robot cannot be placed outside of the specified bounds (defaults to 5x5).
2. The robot will stop reacting to input once it has reached the edge of the table.
