Highlights of Rune


Rune scripts

You can run Rune programs with the bundled CLI:

cargo run --bin rune -- run scripts/hello_world.rn

If you want to see detailed diagnostics of your program while it's running, you can use:

cargo run --bin rune -- run scripts/hello_world.rn --dump-unit --trace --dump-vm

See --help for more information.


Running scripts from Rust

You can find more examples in the examples folder.

The following is a complete example, including rich diagnostics using termcolor. It can be made much simpler if this is not needed.

use rune::{Context, Diagnostics, Source, Sources, Vm};
use rune::termcolor::{ColorChoice, StandardStream};
use std::sync::Arc;

let context = Context::with_default_modules()?;
let runtime = Arc::new(context.runtime()?);

let mut sources = Sources::new();
sources.insert(Source::memory("pub fn add(a, b) { a + b }")?);

let mut diagnostics = Diagnostics::new();

let result = rune::prepare(&mut sources)
    .with_context(&context)
    .with_diagnostics(&mut diagnostics)
    .build();

if !diagnostics.is_empty() {
    let mut writer = StandardStream::stderr(ColorChoice::Always);
    diagnostics.emit(&mut writer, &sources)?;
}

let unit = result?;
let mut vm = Vm::new(runtime, Arc::new(unit));

let output = vm.call(["add"], (10i64, 20i64))?;
let output: i64 = rune::from_value(output)?;

println!("{}", output);
