- The challenge is to build a Forth-like interpreter, a stack-oriented programming language designed by Charles H. Moore.
- Forth is used in various applications like computer games, firmware, and spaceflight software.
- The interpreter should support basic operations like arithmetic, stack manipulation, conditionals, loops, and user-defined words.
- Key features to implement include a REPL (Read-Eval-Print Loop), handling integers, and basic mathematical operations.
- Additional features include stack manipulation words (dup, drop, rot, over, swap), printing words (., emit, cr, ."), and defining new words.
- Conditionals and loops should be supported to enable more complex programs like Fibonacci sequence and FizzBuzz.
- The interpreter should also run Forth-like code from script files.
- Resources for learning Forth include 'Starting FORTH' by Leo Brodie and 'Easy Forth'.
- Further enhancements could include compiling the code or leveraging the LLVM backend.
