FCK

A simple Brainfuck lexer, parser, and interpreter.

Examples

Using run and run_file.

use fck::{run, run_file};
 
fn main() -> fck::Result<()> {
  run("+++++++++.[->+<]")?;
  run_file("path/to/file")?;
}

Using the individual modules.

use fck::lexer::lex;
use fck::parser::parse;
use fck::interpreter::Interpreter;
 
fn main() -> fck::Result<()> {
  let tokens = lex("source code")?;
  let ast = parse(&tokens)?;
  let mut interpreter = Interpreter::new();
  interpreter.run(&ast)?;
}
