Actions & Booking Class

Slangify::Tutorial::Actions uses the Actionable role to auto-populate a Booking object from a successful grammar match.

The Booking Class

use Actionable;

class Booking does Actionable {
    has Str $.name;
    has Int $.party;
    has Str $.time;
    has Str $.restaurant;
    has Str $.date;

    method raku { self.action-to-json }
}

The Actionable role wires named grammar captures to attributes automatically. Int attributes are coerced from the capture string via +$raw.

Actions Class

class Slangify::Tutorial::Actions {
    method TOP($/) {
        make Booking.action($/)
    }
}

Booking.action($/) is the Actionable entry point — it reads all named captures from $/ and populates the matching attributes.

JSON Output

$booking.raku delegates to action-to-json, returning a JSON string with all public attributes.
