go-ini
======
INI parsing library for Go (golang).
View the API documentation [here](http://godoc.org/github.com/vaughan0/go-ini).
Usage
-----
Parse an INI file:
```go
import "github.com/vaughan0/go-ini"
file, err := ini.LoadFile("myfile.ini")
```
Get data from the parsed file:
```go
name, ok := file.Get("person", "name")
if !ok {
panic("'name' variable missing from 'person' section")
}
```
Iterate through values in a section:
```go
for key, value := range file["mysection"] {
fmt.Printf("%s => %s\n", key, value)
}
```
Iterate through sections in a file:
```go
for name, section := range file {
fmt.Printf("Section name: %s\n", name)
}
```
File Format
-----------
INI files are parsed by go-ini line-by-line. Each line may be one of the following:
* A section definition: [section-name]
* A property: key = value
* A comment: #blahblah _or_ ;blahblah
* Blank. The line will be ignored.
Properties defined before any section headers are placed in the default section, which has
the empty string as it's key.
Example:
```ini
# I am a comment
; So am I!
[apples]
colour = red or green
shape = applish
[oranges]
shape = square
colour = blue
```
