Rune scripts

You can run Rune programs with the bundled CLI:

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 --trace

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.
