Pure-go library for cross-platform thread-safe local peer discovery using UDP multicast. I needed to use peer discovery for croc and everything I tried had problems, so I made another one.

Make sure you have Go 1.5+.

go get -u github.com/schollz/peerdiscovery

The following is a code to find the first peer on the local network and print it out.

discoveries, _ := peerdiscovery.Discover(peerdiscovery.Settings{Limit: 1})
for _, d := range discoveries {
    fmt.Printf("discovered '%s'\n", d.Address)
}

Here's the output when running on two computers. (Run these gifs in sync by hitting Ctl + F5).
