The idea is that matchDebug() returns something more useful than just a boolean value. In both the cases here (adblockplus and tsurlfilter) it returns the filter text.

const result = TSUrlFilter.hostsOnly ?
this.matchHostname(url) :
this.matchRequest({ url, frameUrl, type });
return result === null ? null : result.ruleText;
}
};

If the engine does not implement matchDebug() the default value is null. In the end every engine should implement something useful.

matchDebug = engine.matchDebug({ type: WEBREQUEST_OPTIONS[cpt], frameUrl, url });
}

output.push({ index, url, frameUrl, cpt, match, matchDebug });
}

Output is pretty so it can be used with tools like diff.
