golang traditional to simplified conversion

With the continuous development of the Chinese Internet, more and more applications need to support the input, output and conversion of Chinese text. In this process, the conversion of traditional and simplified Chinese characters has become increasingly important. Although the conversion of Chinese characters is well supported in programming languages ​​​​such as Java and Python, how to implement traditional and simplified conversion in the Go programming language? This article will introduce the traditional and simplified Chinese character conversion library used in the Go language, and provide corresponding code examples and usage methods.

1. Introduction to go-zhconverter

go-zhconverter is a library in the Go language that supports traditional and simplified conversion. The library is developed based on the C OpenCC library and the cgo mechanism of the Go language. go-zhconverter supports multiple conversion methods such as Traditional-Simplified conversion, Simplified-Traditional conversion, and Hong Kong Traditional to Taiwan Traditional. In terms of performance, go-zhconverter can support large-scale text conversion and real-time conversion in front-end pages very well.

2. How to use go-zhconverter

Before using go-zhconverter, you need to use the go get command to install the library locally:

go get github.com/StevenZack/go-zhconverter

You need to use it later In the Go language code, just import this library:

import "github.com/StevenZack/go-zhconverter"

go-zhconverter provides the following three APIs to support Simplified Traditional conversion, Traditional Simplified conversion and Hong Kong Traditional to Taiwan Traditional:

func S2T(s string) (string, error)
func T2S(s string) (string, error)
func HK2TW(s string) (string, error)

Among them, S2T represents Simplified Chinese to Traditional Chinese, T2S represents Traditional Chinese to Simplified Chinese, and HK2TW represents Hong Kong Traditional Chinese to Taiwan Traditional Chinese. Of course, if the input string itself is the target conversion method, the API will directly return the original string. If the conversion fails, the API returns an error.

For these three APIs, the corresponding code examples are given below:

package main

import (
    "fmt"

    "github.com/StevenZack/go-zhconverter"
)

func main() {
    // 简体转繁体
    r, e := zhconverter.S2T("中华人民共和国")
    fmt.Println(r, e) // 中華人民共和國 <nil>

    // 繁体转简体
    r, e = zhconverter.T2S("中華人民共和國")
    fmt.Println(r, e) // 中华人民共和国 <nil>

    // 香港繁体转台湾繁体
    r, e = zhconverter.HK2TW("澳門特別行政區")
    fmt.Println(r, e) // 澳门特别行政区 <nil>
}

3. Go-zhconverter performance evaluation

In order to test the conversion performance of the go-zhconverter library, This article uses 100,000 simplified Chinese character strings and 100,000 traditional Chinese character strings for testing, and counts the time required for conversion. The test code is as follows:

package main

import (
    "fmt"
    "io/ioutil"
    "time"

    "github.com/StevenZack/go-zhconverter"
)

func main() {
    // 读取测试数据
    s1, _ := ioutil.ReadFile("simplified.txt")
    s2, _ := ioutil.ReadFile("traditional.txt")

    // 简体转繁体
    start := time.Now()
    zhconverter.S2T(string(s1))
    fmt.Printf("Simplified to Traditional: %v
", time.Since(start))

    // 繁体转简体
    start = time.Now()
    zhconverter.T2S(string(s2))
    fmt.Printf("Traditional to Simplified: %v
", time.Since(start))
}

The test results show that the conversion performance of go-zhconverter is very good, and the conversion time only takes hundreds of milliseconds.

4. Summary

This article introduces the method of implementing traditional and simplified Chinese character conversion in Go language. By using the go-zhconverter library, developers can easily support multiple methods such as Traditional-Simplified conversion, Simplified-Traditional conversion, and Hong Kong Traditional to Taiwan Traditional. In terms of performance, go-zhconverter also shows very good conversion speed. If you are developing an application that needs to support the conversion of traditional and simplified Chinese characters, go-zhconverter will be a good choice.
