ejabberd - Comments for "Using mod_pubsub via console"

Okay, so i just figured out

Okay, so i just figured out in get_items/2 case:
The args type in the ejabberd_commands declaration must be binary:

args = [{host, binary}, {node, binary}],

And a native call for get_items/2 looks like this:

mod_pubsub:get_items(<<"pubsub.mydomain">>, <<"NodeName">>)

If the node got string instead of binary, it wont run in error or warning, just simply will not found the node.

Yea i got this idea too, but

Yea i got this idea too, but after compile pubsub (either without changes) the ejabberd wont start and return with this error:

I found the same error in forums with other modules, but can't solve this problem. And this is not a priority problem for me.

You can know what arguments, and in what format they are expected, if you add some debug lines like this one, recompile, install, then trigger the code with a normal client, and see the log lines in the ejabberd log:
