An uncompromising brainfuck interpreter in 80 lines of scala. The amount of available cells is limited only by the RAM available. Cells are 1 Byte in size. Internally, the machine's state is never mutated, every state shares the majority of its structure with the previous / next states.
How to use:
mkdir bytecode scalac -d bytecode brainfuck.scala cd bytecode scala Brainfuck ../examples/hanoi.bf # Or the path of another brainfuck program
- Fix input requiring a newline character to register. (This is difficult, as reading input one character at a time requires switching the console to 'raw' mode, as opposed to 'cooked' (line-by line) mode. There is no cross-platform way of doing this, hence it is not supported by Java or Scala, and I won't be implementing it for brainfuck.)
