JsonConfigReader is a proxy for [golang's io.Reader](http://golang.org/pkg/io/#Reader) that strips line comments and trailing commas, allowing you to use json as a *reasonable* config format.
|
||
|
|
|
||
|
|
Comments start with `//` and continue to the end of the line.
|
||
|
|
|
||
|
|
If a trailing comma is in front of `]` or `}` it will be stripped as well.
|
||
|
|
|
||
|
|
|
||
|
|
Given `settings.json`
|
||
|
|
|
||
|
|
{
|
||
|
|
"key": "value", // k:v
|
||
|
|
|
||
|
|
// a list of numbers
|
||
|
|
"list": [1, 2, 3],
|
||
|
|
}
|
||
|
|
|
||
|
|
|
||
|
|
You can read it in as a *normal* json file:
|
||
|
|
|
||
|
|
package main
|
||
|
|
|
||
|
|
import (
|
||
|
|
"encoding/json"
|
||
|
|
"fmt"
|
||
|
|
"github.com/DisposaBoy/JsonConfigReader"
|
||
|
|
"os"
|
||
|
|
)
|
||
|
|
|
||
|
|
func main() {
|
||
|
|
var v interface{}
|
||
|
|
f, _ := os.Open("settings.json")
|
||
|
|
// wrap our reader before passing it to the json decoder
|
||
|
|
r := JsonConfigReader.New(f)
|
||
|
|
json.NewDecoder(r).Decode(&v)
|
||
|
|
fmt.Println(v)
|
||
|
|
}
