Intro

A go package for configuration parsing. Automagically populates a configuration struct using configuration files & command line arguments.

It aims to be modular and easily extendible to support other formats. Only INI format supported for now.

Usage and examples

An example of utilization::

    type myConf struct {
            Address string
            Port    string
            // A command line flag "-users", which expects an int value,
            // will be created.
            // Same key name will be searched in configuration file.
            NumberOfUsers int `conf:"users,number of users,"`
            Daemon        bool
            Message       string
    }

    func Example() {
            // To create a dafault value for a flag
            // assign it when instantiate the conf struct.
            c := myConf{Message: "A default value"}
            conf.Path = "test_data/one.ini"
            err := conf.Parse(&c)
            if err != nil {
                    log.Fatal("Unable to parse configuration", err)
            }
            fmt.Println("address:", c.Address)
            fmt.Println("port:", c.Port)
            fmt.Println("number of users:", c.NumberOfUsers)
    }

See the flag arguments that are automagically created::

    go run main.go -h
