package mangos is an implementation in pure Go of the SP ("Scalable Protocols") protocols. This makes heavy use of go channels, internally, but it can operate on systems that lack support for cgo. It has no external dependencies.
The reference implementation of the SP protocols is available as nanomsg
The design is intended to make it easy to add new transports with almost trivial effort, as well as new topologies ("protocols" in SP terminology.)
At present, all of the Req/Rep, Pub/Sub, Pair, Bus, Push/Pull, and Surveyor/Respondent patterns are supported.
Additionally, there is an experimental new pattern called STAR available. This pattern is like Bus, except that the messages are delivered not just to immediate peers, but to all members of the topology. Developers must be careful not to create cycles in their network when using this pattern, otherwise infinite loops can occur.
Supported transports include TCP, inproc, IPC, and TLS. TLS support is experimental. Use addresses of the form "tls+tcp://:" to access it. Note that ipc:// is not supported on Windows (by either this or the reference implementation.) Forcing the local TCP port in Dial is not supported yet (this is rarely useful).
Basic interoperability with nanomsg has been tested with nanocat.
Consider this a work-in-progress, and use at your own risk.

$ go get github.com/gdamore/mangos
After this command mangos is ready to use. Its source will be in:
$GOPATH/src/pkg/github.com/gdamore/mangos
You can use go get -u -a to update all installed packages.
For docs, see http://godoc.org/github.com/gdamore/mangos or run:
$ godoc github.com/gdamore/mangos
This package supports internal self tests, which can be run in the idiomatic Go way, although it uses a separate test sub-package:
$ go test github.com/gdamore/mangos/test
There are also internal benchmarks available:
$ go test -bench=. github.com/gdamore/mangos/test
Some examples are posted in the directories under examples/ The examples are rewrites (in Go) of Tim Dysinger's libnanomsg examples, which are located at
http://tim.dysinger.net/posts/2013-09-16-getting-started-with-nanomsg.html
godoc in the example directories will yield information about how to run each example program.
Enjoy!
