Cfg

Cfg is a json configuration package for Go

Features:

You can define your config items in your application as a struct.
You can save a json template of your struct
You can save runtime modifications to the config

Docs:

import "bitbucket.org/gotamer/cfg"

func Load(filename string, o interface{}) (err error)

Load gets your config from the json file, and fills your struct with the option

func Save(filename string, o interface{}) (err error)

Save will save your struct to the given filename, this is a good way to create a json template

Example:

    package main

    import (
        "fmt"
        "bitbucket.org/gotamer/cfg"
        "os"
    )

    var Cfg *MainCfg

    type MainCfg struct {
        Name  string
    }

    func main() {
        Cfg = &MainCfg{"defaultAlias"}
        cfgpath := os.Getenv("GOPATH") + "/etc/myappname.json"
        err := cfg.Load(cfgpath, Cfg)
        if err != nil {
            cfg.Save(cfgpath, Cfg)
            fmt.Println("\n\tPlease edit your configuration at: ", cfgpath, "\n")
            os.Exit(0)
        }
        fmt.Printf("%s", Cfg)
