common: remove config.go

Browse Source 
The code in config.go is unused. The main reason for removing it is to
get rid github.com/rakyll/goini in Godeps (it has no license).

# globalconf
[![Build Status](https://travis-ci.org/rakyll/globalconf.png?branch=master)](https://travis-ci.org/rakyll/globalconf)
Effortlessly persist/retrieve flags of your Golang programs. If you need global configuration instead of requiring user always to set command line flags, you are looking at the right package. `globalconf` allows your users to not only provide flags, but config files and environment variables as well.
## Usage
~~~ go
import "github.com/rakyll/globalconf"
~~~
### Loading a config file
By default, globalconf provides you a config file under `~/.config/<yourappname>/config.ini`.
~~~ go
globalconf.New("appname") // loads from ~/.config/<appname>/config.ini
~~~
If you don't prefer the default location you can load from a specified path as well.
~~~ go
globalconf.NewWithOptions(&globalconf.Options{
Filename: "/path/to/config/file",
})
~~~
You may like to override configuration with env variables. See "Environment variables" header to see how to it works.
~~~ go
globalconf.NewWithOptions(&globalconf.Options{
Filename: "/path/to/config/file",
EnvPrefix: "APPCONF_",
})
~~~
### Parsing flag values
`globalconf` populates flags with data in the config file if they are not already set.
~~~ go
var (
flagName = flag.String("name", "", "Name of the person.")
flagAddress = flag.String("addr", "", "Address of the person.")
)
~~~
Assume the configuration file to be loaded contains the following lines.
name = Burcu
addr = Brandschenkestrasse 110, 8002
And your program is being started, `$ myapp -name=Jane`
~~~ go
conf, err := globalconf.New("myapp")
conf.ParseAll()
~~~
`*flagName` is going to be equal to `Jane`, whereas `*flagAddress` is `Brandschenkestrasse 110, 8002`, what is provided in the configuration file.
### Custom flag sets
Custom flagsets are supported, but required registration before parse is done. The default flagset `flag.CommandLine` is automatically registered.
~~~ go
globalconf.Register("termopts", termOptsFlagSet)
conf.ParseAll() // parses command line and all registered flag sets
~~~
Custom flagset values should be provided in their own segment. Getting back to the sample ini config file, termopts values will have their own segment.
name = Burcu
addr = Brandschenkestrasse 110, 8002
[termopts]
color = true
background = ff0000
### Environment variables
If an EnvPrefix is provided, environment variables will take precedence over values in the configuration file.
Set the `EnvPrefix` option when calling `globalconf.NewWithOptions`.
An `EnvPrefix` will only be used if it is a non-empty string.
Command line flags will override the environment variables.
~~~ go
opts := globalconf.Options{
EnvPrefix: "MYAPP_",
Filename: "/path/to/config",
}
conf, err := globalconf.NewWithOptions(&opts)
conf.ParseAll()
~~~
With environment variables:
APPCONF_NAME = Burcu
and configuration:
name = Jane
addr = Brandschenkestrasse 110, 8002
`name` will be set to "burcu" and `addr` will be set to "Brandschenkestrasse 110, 8002".
### Modifying stored flags
Modifications are persisted as long as you set a new flag and your GlobalConf
object was configured with a filename.
~~~ go
f := &flag.Flag{Name: "name", Value: val}
conf.Set("", f) // if you are modifying a command line flag
f := &flag.Flag{Name: "color", Value: val}
conf.Set("termopts", color) // if you are modifying a custom flag set flag
~~~
### Deleting stored flags
Like Set, Deletions are persisted as long as you delete a flag's value and your
GlobalConf object was configured with a filename.
~~~ go
conf.Delete("", "name") // removes command line flag "name"s value from config
conf.Delete("termopts", "color") // removes "color"s value from the custom flag set
~~~
