go-iconv: Go 语言的编码转换

[shiwei xu]

Go 语言官方没有提供处理 utf8、unicode 之外字符编码的包。故此在 libiconv 上包装了一个：

Summary

go-iconv is a libiconv wrapper for go. libiconv Convert string to requested character encoding.

go-iconv project's homepage is: https://github.com/xushiwei/go-iconv

Install

git clone g...@github.com:xushiwei/go-iconv.git
cd go-iconv
make install

Example

Convert string

import (
    "fmt"
    "xushiwei.com/iconv"
)


func main() {

    cd, err := iconv.Open("gbk", "utf-8")

    if err != nil {
        fmt.Println("iconv.Open failed!")

        return
    }
    defer cd.Close()

    gbk := cd.ConvString("你好，世界！")


    fmt.Println(gbk)
}

Output to io.Writer

import (
    "fmt"
    "xushiwei.com/iconv"
)


func main() {

    cd, err := iconv.Open("gbk", "utf-8")

    if err != nil {
        fmt.Println("iconv.Open failed!")

        return
    }
    defer cd.Close()

    output := ... // eg. output := os.Stdout || ouput, err := os.Create(file)

    autoSync := false // buffered or not
    bufSize := 0 // default if zero

    w := iconv.NewWriter(cd, output, bufSize, autoSync)


    fmt.Fprintln(w, "你好，世界！")


    w.Sync() // if autoSync = false, you need call Sync() by yourself
}

Input from io.Reader

import (
    "fmt"
    "io"
    "os"
    "xushiwei.com/iconv"

)

func main() {

    cd, err := iconv.Open("utf-8", "gbk") // gbk => utf8

    if err != nil {
        fmt.Println("iconv.Open failed!")

        return
    }
    defer cd.Close()

    input := ... // eg. input := os.Stdin || input, err := os.Open(file)

    bufSize := 0 // default if zero
    r := iconv.NewReader(cd, input, bufSize)


    _, err = io.Copy(os.Stdout, r)

    if err != nil {
        fmt.Println("\nio.Copy failed:", err)

        return
    }
}

这个库没有更新到go1，有人fork更新了

go get github.com/grafov/go-iconv

嗯，我回头 merge 下这个 fork 的内容。
