Do you think we are missing an alternative of comment or a related project?
README
comment
Golang package for use comments in JSON config files
Motivation
json config file: config.json
{
"name": "example",
"address": "192.168.0.1",
"active": true
}
How we can change address?
Create a new file config2.json or fix in the current one.
Both variants are not convenient.
What is proposed
Introduce end-line comment. For shielding use the symbol #.
new json-config file with comments config.cjson
{
"name": "example",
# "address": "192.168.0.1", - this line is commented
"address": "192.168.0.2", # New address!
"active": true
}
Easier and convenient than previous both variants.
For parse this file first use the function comment.Trim(data).
We obtain the following:
{
"name": "example",
"address": "192.168.0.2",
"active": true
}
Next, we use standard parser json.Unmarshal
package main
import (
"encoding/json"
"fmt"
"io/ioutil"
"log"
"github.com/toelsiba/comment"
)
type Config struct {
Name string `json:"name"`
Address string `json:"address"`
Active bool `json:"active"`
}
func main() {
data, err := ioutil.ReadFile("config.cjson")
if err != nil {
log.Fatal(err)
}
data = comment.Trim(data)
fmt.Println(string(data))
var config Config
err = json.Unmarshal(data, &config)
if err != nil {
log.Fatal(err)
}
fmt.Printf("%+v\n", config)
}
Or more short variant:
func main() {
var c Config
err := comment.ReadConfig("config.cjson", &c)
if err != nil {
log.Fatal(err)
}
fmt.Println(c)
}
If you need have symbol # in line - used doublet ##.
