package main

import (
	"fmt"
	"github.com/ragsagar/netstringer"
)

func main() {
	input := []byte("hello world!")
	output := netstringer.Encode(input)
	fmt.Println(string(output)) // 12:hello world!,
}

$go run main.go
12:hello world!,

To decode a stream of incoming data into netstring

// main.go
package main

import (
	"fmt"
	"github.com/ragsagar/netstringer"

func main() {
        // To mock the incoming stream of data.
	inputs := []string{
		"12:hello world!,",
		"17:5:hello,6:world!,,",
		"12:hello ",
		"world!,",
	}
	decoder := netstringer.NewDecoder()
	go func() {
		for _, input := range inputs {
			decoder.FeedData([]byte(input))
		}
		close(decoder.DataOutput)
	}()

	for output := range decoder.DataOutput {
		fmt.Println(string(output))

	}
}

$go run main.go 
hello world!
5:hello,6:world!,
