['exclude', []], // a default array means this flag is a default array of string
['help', false], // a default boolean means this flag is a boolean
]);
tprint(data);
// example.js
export async function main(ns) {
const data = ns.flags([
['delay', 0], // a default number means this flag is a number
['server', 'foodnstuff'], // a default string means this flag is a string
['exclude', []], // a default array means this flag is a default array of string
['help', false], // a default boolean means this flag is a boolean
]);
ns.tprint(data);
}
// [home ~/]> run example.script
// {"_":[],"delay":0,"server":"foodnstuff","exclude":[],"help":false}
// [home ~/]> run example.script --delay 3000
// {"_":[],"server":"foodnstuff","exclude":[],"help":false,"delay":3000}
// [home ~/]> run example.script --delay 3000 --server harakiri-sushi
// {"_":[],"exclude":[],"help":false,"delay":3000,"server":"harakiri-sushi"}
// [home ~/]> run example.script --delay 3000 --server harakiri-sushi hello world
// {"_":["hello","world"],"exclude":[],"help":false,"delay":3000,"server":"harakiri-sushi"}
// [home ~/]> run example.script --delay 3000 --server harakiri-sushi hello world --exclude a --exclude b
// {"_":["hello","world"],"help":false,"delay":3000,"server":"harakiri-sushi","exclude":["a","b"]}
// [home ~/]> run example.script --help
