sortedmap

The sortedmap package provides some utility methods to sort maps by keys or values

See documentation at https://godoc.org/github.com/gobs/sortedmap

Usage

The most common use cases is to print the content of a map sorted by key:

unsorted := map[string]interface{}{
	"b": 2.0,
	"a": 1,
	"c": true,
	"e": nil,
	"d": "four",
}

fmt.Println(sortedmap.AsSortedMap(unsorted))	

// or

for _, ele := range sortedmap.AsSortedMap(unsorted) {
	fmt.Println(ele)    // implements Stringer
	
	fmt.Println(ele.Key + ":" + ele.Value)
}

You can also generate a JSON object with sorted keys:

jbuffer, _ := json.MarshalIndent(sortedmap.AsSortedMap(unsorted), "", "  ")
fmt.Println(string(jbuffer)
