messenger

Multi-threaded, console-based, 2-way instant messaging system with
 authentication, based on NNG scalability protocols.

R binding for NNG (Nanomsg Next Gen), a successor to ZeroMQ. NNG is
a socket library providing high-performance scalability protocols,
implementing a cross-platform standard for messaging and communications.
Serves as a concurrency framework for building distributed applications,
utilising 'Aio' objects which automatically resolve upon completion of
asynchronous operations.

messenger function

<dl><dt>url</dt>
<dd>a URL to connect to, specifying the transport and address as
a character string e.g. 'tcp://127.0.0.1:5555' (see transports).</dd>
<dt>auth</dt>
<dd>[default NULL] an R object (possessed by both parties) which
serves as a pre-shared key on which to authenticate the communication.
Note: the object is never sent, only a random subset of its SHA256 hash.</dd></dl>

Arguments

Type outgoing messages and hit return to send.
The timestamps of outgoing messages are prefixed by <code>&gt;</code> and that of
 incoming messages by <code>&lt;</code>.
<code>:q</code> is the command to quit.
Both parties must supply the same argument for 'auth', otherwise the
 party trying to connect will receive an 'authentication error' and be
 disconnected immediately.
NOTE: This is currently a proof of concept with an experimental
 authentication protocol and should not be used for critical applications.
