Hello guys , I am trying to make a MAC address finder with the API, it should be very simple - but I am doing a mistake somewhere - this is my script
$API->write('/ip/arp/print');
$API->write('?address=1.2.3.4');
$res=$API->read(true);
I want to see info only for IP 1.2.3.4 - but this code gives me whole ARP table ?
I’m assuming this is the wiki client, no?
With that client, you need to pass false as a second argument when making any requests more complicated than a single word, and only omit when you’re ready with the request i.e.
$API->write('/ip/arp/print', false);
$API->write('?address=1.2.3.4');
$res=$API->read(true);
echo $res[0]['mac-address'];
With the elsewhere client, you can do it instead with
$res = $client->sendSync(new Request('/ip/arp/print', null, Query::where('address', '1.2.3.4')));
echo $res->getArgument('mac-address');
Ah yes , very simple mistake 
but that was it ! Now it works.
Also I was very happy to find this new PEAR2 API , so I will try it ASAP - BTW - Bulgaria/Sofia here
maybe you set up wiki page for your client and set up there some version of code and then link where to get current version.
Your code while being good, it seems, is placed elsewhere and thus, we do not have the copy of it, and as a result it is not known how long it will be available. For example, C++ libraries where recently pulled without any notification
Funny you should mention that… I was just preparing this page. I planned to first release my upcoming version, as it has some breaking changes in it (e.g. the query becomes a second argument; I notice too many people don’t use tags, but need to use queries as required by set/remove/disable commands), and I wouldn’t want to hook people into the old way before that.
But then again, I suppose that while I’m still actively working on the thing, it won’t be such a big problem, so feel free to include it.
good, just mention the license you are are sharing this code with (you can link to the license you are using form wiki article) and preferably somehow add everything that is required to use your code in case some of external resources go down.
