A brainfuck Interpreter/REPL written in Rust.

tf program.b

Execute without arguments to start the REPL.

There isn't much in the ways of a concrete specification floating around, so this version adheres to the more common rules of:

• "Machine" is 30,000 cells, all 1 byte in size. All cells are initialized to 0;
• Decrementing the cell pointer below index 0 causes a panic
• Incrementing the cell pointer above index 29,999 causes a panic
• Decrementing a cell value below 0 causes an underflow
• Incrementing a cell value above 255 causes an overflow
• Characters that are not a part of the 8 standard operators are ignored (though the REPL obviously has some "fondness" for newline characters)
