Variables

var GzipLevel = gzip.BestSpeed

GzipLevel is default Gzip compression level

Functions

func Read

func Read(file string, v interface{}) error

Read reads and decode JSON file

Example

var data = make(map[string]int)

err := Read("/path/to/file.json", data)

if err != nil {
	fmt.Printf("Error: %v\n", err)
}

func ReadGz

func ReadGz(file string, v interface{}) error

ReadGz reads and decode gzipped JSON file

Example

var data = make(map[string]int)

err := ReadGz("/path/to/file.gz", data)

if err != nil {
	fmt.Printf("Error: %v\n", err)
}

func Write

func Write(file string, v interface{}, perms ...os.FileMode) error

Write encodes data to JSON and save it to file

Example

var data = make(map[string]int)

data["john"] = 100
data["bob"] = 300

err := Write("/path/to/file.json", data, 0600)

if err != nil {
	fmt.Printf("Error: %v\n", err)
}

func WriteGz

func WriteGz(file string, v interface{}, perms ...os.FileMode) error

Write encodes data to gzipped JSON and save it to file

Example

var data = make(map[string]int)

data["john"] = 100
data["bob"] = 300

err := WriteGz("/path/to/file.gz", data, 0600)

if err != nil {
	fmt.Printf("Error: %v\n", err)
}
