Ignore

The quite handy command ignore from Jaseci allows you to skip(ignore) visiting nodes or edges when traversing.

node person: has name;
edge family;
edge friend;

walker build_example {
    spawn here +[friend]+> node::person(name="Joe");
    spawn here +[friend]+> node::person(name="Susan");
    spawn here +[family]+> node::person(name="Matt");
    spawn here +[family]+> node::person(name="Dan");
    }

walker init {
    root {
        spawn here walker::build_example;
    ignore -[family]->;
    take -->;
    }
person {
    std.out(here.name);
    take-->;
    }
}

Expected Output:

Joe
Susan

You can see in the above example; the nodes connected with family type edges is ignored while visiting nodes. The magic is happening because of the ignore -[family]->; line. Change the edge type and play with the code.
