INI file decoder for Go lang. Idea is to have an unmarshaller similar to JSON - specify parts of the file you want coded with structs and tags.
For example, for an INI file like this:
[Pod_mysql]
cache_size = 2000
default_socket = /tmp/mysql.sock
[Mysql]
default_socket = /tmp/mysql.sock
Decode into a structure like this:
type MyIni struct {
PdoMysql struct {
CacheSize int `ini:"cache_size"`
DefaultSocket string `ini:"default_socket"`
} `ini:"[Pdo_myqsl]"`
Mysql struct {
DefaultSocket string `ini:"default_socket"`
} `ini:"[Myqsl]"`
}
With code like this:
var config MyIni
var b []byte // config file stored here
err := ini.Unmarshal(b, &config)
Over the years, INI files have grown from simple name=value lists of properties to files that support arrays and arrays of structures. For example, to support playlists a music config file may look like this:
[CREATE SONG]
SongId=21348
Title=Long Way to Go
Artist=The Coach
[CREATE SONG]
SongId=9855
Title=The Falcon Lead
Artist=It Wasn't Safe
[CREATE PLAYLIST]
PlaylistId=438432
Title=Acid Jazz
Song=21348
Song=482
Song=9855
[CREATE PLAYLIST]
PlaylistId=2585
Title=Lounge
Song=7558
Song=25828
With GO-INI, parsing is as simple as defining the structure and unmarshalling it.
package main
import (
"encoding/json"
"github.com/sspencer/go-ini"
"io/ioutil"
"log"
"os"
)
type TunePlayer struct {
Songs []struct {
SongId int
Title string
Artist string
} `ini:"[CREATE SONG]"`
Playlists []struct {
PlaylistId int
Title string
SongIds []int `ini:"Song"`
} `ini:[CREATE PLAYLIST]`
}
func main() {
var player TunePlayer
content, err := ioutil.ReadFile("./tunes.ini")
if err != nil {
log.Fatal(err)
}
err = ini.Unmarshal(content, &player)
if err != nil {
log.Fatal(err)
}
// Output same struct as JSON to verify parsing worked
enc := json.NewEncoder(os.Stdout)
if err := enc.Encode(&player); err != nil {
log.Println(err)
}
}
Need to parse inner array of structs
struct {
Playlists []struct {
Id int
Title string
Programs []struct {
Id int
Mix string
Separation int
} `ini:"Play Program"`
} `ini:"[CREATE PLAYLIST]"`
}
[CREATE PLAYLIST]
ID=6524
Title=Pop
Start Schedule
Play Program
ID=391
Mix=RAND
Play Program
ID=3912
Separation=10
End Schedule
