Struct Interpreter

pub struct Interpreter { /* private fields */ }

The interpreter used for running whitespace

Implementations

impl Interpreter

pub fn new(code: String, print_instructions: bool) -> Interpreter

Create an Interpreter from a source code passed as the argument

The print_instructions parameter prints the instructions. This should be set to True when debugging the code

Example

let source = String::from("   \t\t\n");
let interpreter = Interpreter::new(source, false);

pub fn from_file(file: &str, print_instructions: bool) -> Option<Interpreter>

Initialize an interpreter from a file

The print_instructions parameter prints the instructions. This should be set to True when debugging the code

Example

let interpreter = Interpreter::from_file("main.ws", false);

pub fn write(&mut self, num: i32)

Write a value on top of the stack Should be used when the Status is set to ReadChar/ReadInt

pub fn step(&mut self) -> Result<Status, Error>

Step to the next instructions

See Status and Error for the return value

pub fn pc(&self) -> usize
