ncsa to json converter written in Go

A very simple application written in Go.
It parses Apache Common Logs and returns json instead.
Incredibly simple but works incredibly fast also.

package main

import (
    "fmt"
    "strings"
    "encoding/json"
    "bufio"
    "os"
)

func main() {
    type Request struct {
        Client string `json:"client"`
        Url string `json:"url"`
        Status string `json:"status"`
        Size string `json:"size"`
        Time string `json:"time"`
        Method string `json:"method"`
        Ua string `json:"user-agent"`
        Referer string `json:"referer"`
    }
    in := bufio.NewReader(os.Stdin)
    for {
            log, err := in.ReadString('\n')
            if err != nil {
            fmt.Println("EOF")
            os.Exit(1) // if you return error
    }
    var arr = strings.Split(log, " ")
    var client string = arr[0]
    var url string = arr[6]
    var status string = arr[8]
    var size string = arr[9]
    var time string = arr[3] + " " + arr[4]
    var method string = arr[5][1:]
    arr = strings.Split(log, "\"")
    var ua string = arr[5]
    var referer string = arr[3]

    r := Request {client, url, status, size, time, method, ua, referer}
    b, _ := json.MarshalIndent(r, "", "  ")
    fmt.Println(string(b))
    }
}
