Fixedwidth

Build Status Report Code coverage

Fixedwidth is a Go package that provides a simple way to define fixed-width data, fast encoding and decoding also is the project's target.

Character encoding supported

UTF-8

Getting Started

Installation

To start using Fixedwidth, run go get:

$ go get github.com/huydang284/fixedwidth

How we limit a struct field

To limit a struct field, we use fixed tag.

Example:

type people struct {
    Name string `fixed:"10"`
    Age  int    `fixed:"3"`
}

If the value of struct field is longer than the limit that we defined, redundant characters will be truncated.

Otherwise, if the value of struct field is less than the limit, additional spaces will be appended.

Encoding

We can use Marshal function directly to encode fixed-width data.

package main

import (
    "fmt"
    "github.com/huydang284/fixedwidth"
)

type people struct {
    Name string `fixed:"10"`
    Age  int    `fixed:"3"`
}

func main() {
    me := people {
        Name: "Huy",
        Age: 25,
    }
    data, _ := fixedwidth.Marshal(me)
    fmt.Println(string(data))
}

The result will be:

Huy       25 

Decoding

For decoding, we use Unmarshal.

package main

import (
    "fmt"
    "github.com/huydang284/fixedwidth"
)

type people struct {
    Name string `fixed:"10"`
    Age  int    `fixed:"3"`
}

func main() {
    var me people
    data := []byte("Huy       25 ")
    fixedwidth.Unmarshal(data, &me)
    fmt.Printf("%+v", me)
}

The result will be:

{Name:Huy Age:25}
