Projects using native methods

[Robert Dyer]

Curious which projects declare native methods?  Quite a few!

# find use of native modifier in each project
NativePerProject: output sum[string] of int;


visit(input, visitor {
    # only look at the latest snapshot
    before n: CodeRepository -> {
        snapshot := getsnapshot(n);
        foreach (i: int; def(snapshot[i]))
            visit(snapshot[i]);
        stop;
    }
    before m: Modifier ->
        if (m.kind == ModifierKind.OTHER && m.other == "native")
            NativePerProject[input.id] << 1;
});
