Struct Repl

pub struct Repl { /* private fields */ }

Run an read/evaluate/print/loop.

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut repl = spore_vm::repl::Repl::new(spore_vm::Vm::default())?;
    loop {
        if let Err(err) = repl.eval_next_input() {
            match err {
                rustyline::error::ReadlineError::Eof
                | rustyline::error::ReadlineError::Interrupted => return Ok(()),
                err => println!("{err}"),
            }
        }
    }
}

Implementations

impl Repl

pub fn new(vm: Vm) -> Result<Repl>

Create a new REPL.

pub fn into_vm(self) -> Vm

Convert self into a Vm.

pub fn as_vm_mut(&mut self) -> &mut Vm

Get the underlying Vm.

pub fn as_vm(&self) -> &Vm

Get the underlying Vm.

pub fn eval_next_input(&mut self) -> Result<ProtectedVal<'_>>

Evaluate the next user input. The input is read through stdin and the result is written through stdout.
