[go-nuts] trouble passing an argument to a script

[Natxo Asenjo]

hi,

I am writing a script that accepts arguments and flags (using kingpin) but 
am failing miserably so far. One of the arguments is a file name, which 
should be then loaded by an ini library (file is in ini format).

If I hard code the file name in the script, it works, but 

Code:

=====================start ====================================
package main

import (
    "fmt"
    "gopkg.in/alecthomas/kingpin.v2"
    "gopkg.in/ini.v1"
    "os"
)

var (
    config              = kingpin.Flag("config", "configuration 
file").Short('c').Required().ExistingFile()
    url, api, user, pwd = parse_config()
)

func init() {
    kingpin.Parse()
}

func main() {
    fmt.Println("yay")
}

func parse_config() (string, string, string, string) {
    //cfg, err := ini.Load("api.conf")
    fmt.Printf("%v, %s, %T\n", config, config, config)
    cfg, err := ini.Load(config)
    if err != nil {
        fmt.Println(err)
        os.Exit(1)
    }

    url := cfg.Section("").Key("url").String()
    api := cfg.Section("").Key("api").String()
    user := cfg.Section("").Key("user").String()
    pwd := cfg.Section("").Key("password").String()

    return url, api, user, pwd
}

=====================end====================================
and when running it:

$ go run yetanother.go --config api.conf 
0xc0000547e0, %!s(*string=0xc0000547e0), *string
error parsing data source: unknown type '%!s(*string=0xc00008ceb0)'
exit status 1

This must be pretty basic, but I'm stuck :(

Any tips welcome.

Thanks in advance.
