#!/usr/bin/perl -slw
use strict;
use Data::Dump qw(dump pp);
use XML::Rules;

my $parser = XML::Rules->new(
    rules => {
        parameters => sub {
            return '+has_uint64' => ($_[1]->{type} eq 'uint64_t');
        },
        members => sub {
            my ($tag,$attr,$context,$parents) = @_;
            return unless $context->[-2] eq 'classes';
            my $class = $parents->[-2]{name};
            (my $access = $context->[-1]) =~ s/_methods//;
            print "$access $class.$attr->{name} has $attr->{has_uint64
+} uint64 parameter(s)\n"
                if ($attr->{has_uint64});
            return;
        },
        '^enums' => 'skip',
    }
);

$parser->parse(\*DATA);
