zmq4: pure-Go ZeroMQ-4 package

hi there,

I've just pushed a few examples for my pure-Go implementation of ZeroMQ-4 sockets:

• https://github.com/go-zeromq/zmq4

Implemented so far (with tests against the C bindings of pebbe/zmq4):

• pub/sub
• push/pull
• req/rep

Implemented (but not tested yet):

• xpub/xsub
• router/dealer
• pair

Enjoy! (and send PRs )

I've been using pebbe/zmq4 for some time now, I greatly appreciate a pure Go version, Thx!

I will be watching your repo closely, cheers!

I’m not well versed in zmq but saw inproc wasn’t implemented. Is that something that could be implemented with a channel that satisfied the net interfaces your lib expects?

yes, definitely.
IIRC, that's what go-mangos/mangos (a pure Go implementation of nanomsg) is doing.

alternatively, and as a short gap solution, one could use either os.Pipe or net.Pipe.

net.Pipe already uses a couple of chans already:

Sweet! This let's me say goodbye to cgo for one of my projects XD

Aha :)

I'll post a few histograms comparing latency between cgo-based transport and pure-Go based transport in my favorite application.
Nothing earth shattering, between the pure-Go transport has a better figure of merit.

here is the initial preliminary little study:
