# broadcaster

This package implements broadcast type messaging (or event) in a Go idiomatic

way not based on a list of handlers.

This is based on the design invented by [Roger Peppe](https://rogpeppe.wordpress.com/2009/12/01/concurrent-idioms-1-broadcasting-values-in-go-with-linked-channels/)

and the actual implementation from the [gibb package](https://github.com/dagoof/gibb),

modified to only expose channels, which are the prefered way of communicating in Go.

Contrary to ordinary packages which use a list of channels and register/unregister methods,

this package makes use of a linked list of channels to broadcast values in a

fanout way.

## Install

```

$ go get github.com/steeve/broadcaster

```

## How to use

```go

package main

import (

    "fmt"

    "github.com/steeve/broadcaster"

)

func main() {

    b := broadcaster.NewBroadcaster()

    defer b.Close()

    for i := 0; i < 10; i++ {

        go func() {

            read, done := b.Listen()

            defer close(done)

            fmt.Println(<-read)

        }()

    }

    b.Broadcast("sample payload")

}

```
