Simple GO implementatin for storage application configuration as map[string]interface{} in JSON file.

Overview

Package confjson - is a simple tool to read/store configuration in the JSON format file. Values stored as empty interface. So, to use values yo have to convert them to required format.

Note that saved int value will be read as float64!

Functions

func Load

func Load(file string) (map[string]interface{}, error)

Load reads JSON file in to cfg map.

Example

readCfg, err := Load(fileName)

if err != nil {
	log.Fatal(err)
}

for k, v := range readCfg {
	fmt.Printf("%s: %#v\n", k, v)
}

Output:
key1: "value1"
key2: 42
key3: true

func Save

func Save(file string, cfg map[string]interface{}) error

Save stores configuration map in to JSON-formatted file.

Example

conf := map[string]interface{}{
	"key1": "value1",
	"key2": 42,
	"key3": true,
}
err := Save(fileName, conf)
if err != nil {
	log.Fatal(err)
}
// read the file
file, err := os.Open(fileName)
if err != nil {
	log.Fatal(err)
}
data := make([]byte, 100)
l, err := file.Read(data)
if err != nil {
	log.Fatal(err)
}
// remove "{" and "}"
s := string(data[1 : l-1])
s = strings.Replace(s, ",", "\n", -1)
fmt.Println(s)

Output:
"key1":"value1"
"key2":42
"key3":true
