This library is using to parse fixed-width table data like:
```
Name Address Postcode Phone Credit Limit Birthday
Evan Whitehouse V4560 Camel Back Road 3122 (918) 605-5383 1000000.5 19870101
Chuck Norris P.O. Box 872 77868 (713) 868-6003 10909300 19651203
```
## Install
To install the library use the following command:
```
$ go get -u github.com/o1egl/fwencoder
```
## Decoding example
Parsing data from io.Reader:
```go
type Person struct {
Name string
Address string
Postcode int
Phone string
CreditLimit float64 `json:"Credit Limit"`
Bday time.Time `column:"Birthday" format:"20060102"`
}
f, _ := os.Open("/path/to/file")
defer f.Close
var people []Person
err := fwencoder.UnmarshalReader(f, &people)
```
You can also parse data from byte array:
```go
b, _ := ioutil.ReadFile("/path/to/file")
var people []Person
err := fwencoder.Unmarshal(b, &people)
```
## Encoding example
```go
people := []Person{
Name: "John",
Address: "P.O. Box 872",
Phone: "(713) 868-6003",
CreditLimit: 10909300,
Bday: "19651203"
}
b, err := Marshal(&people)
fmt.Println(string(b))
```
or you can directly write to io.Writer
```go
people := []Person{
Name: "John",
Address: "P.O. Box 872",
Phone: "(713) 868-6003",
CreditLimit: 10909300,
Bday: "19651203"
}
err := MarshalWriter(os.Stdout, &people)
```
