Let's talk about how to use Golang to implement Traditional Chinese conversion

In recent years, Golang has become the programming language of choice for more and more developers. It is simple to use, efficient and stable, and supports cross-platform development. In international application development, Traditional Chinese conversion is a common requirement. This article will introduce how to use Golang to implement Traditional Chinese conversion.

1. Introduction to Traditional Chinese conversion

Traditional Chinese is a form of Chinese character expression, mainly distributed in Taiwan, Hong Kong, Macau and other regions of China, as well as overseas Chinese communities. Compared with Simplified Chinese, its characters are more diverse and have more strokes, so it can be a challenge for some users who are not familiar with Traditional Chinese characters to read and type. With the development of globalization and digitization, more and more applications need to support multi-language and multi-region requirements, so Traditional Chinese conversion has also become an important functional requirement.

2. Introduction to Golang

Golang is a programming language launched by Google. It provides a simple, efficient and safe programming method and supports features such as concurrency, garbage collection and memory safety. . Golang's syntax is simple and readable, and it is widely used in network applications, cloud computing, microservices and other fields.

3. Traditional Chinese conversion implementation method

There are many methods to choose from to implement the Traditional Chinese conversion function. We introduce two commonly used methods here:

1. Use third-party libraries

Golang There are many third-party libraries in the open source community that can implement Traditional Chinese conversion functions, for example: https://github .com/axgle/mahonia, https://github.com/andybalholm/cascadia, etc. When using these libraries, you only need to introduce the library files, and then convert the text according to the methods provided by the libraries.

For example, an example of using the go-mahonia library for Traditional Chinese conversion:

package main

import (
    "fmt"
    "github.com/axgle/mahonia"
)

func main() {
    traditional := "憂愁的歌曲自此更悲傷"
    encoder := mahonia.NewEncoder("gbk")
    simplified := encoder.ConvertString(traditional)

    fmt.Println(simplified)
}

2. Implement the Traditional Chinese conversion algorithm

In addition to using third-party libraries, you can also use Traditional Chinese and Corresponding rules for simplified Chinese characters and write traditional Chinese conversion algorithms.

For example, the following code is a dictionary-based Traditional Chinese conversion algorithm:

package main

import (
    "fmt"
    "strings"
)

var dict map[rune]rune

func init() {
    dict = make(map[rune]rune)

    simplified := "的一是了我不人在有他这上个地到大里说去来和子时要就出也得你对以会着天下面而多自后然于心前又其起所"

    traditional := "的一是了我不人在有他這上個地到大裡說去來和子時要就出也得你對以會著天下面而多自後然於心前又其起所"

    for i := 0; i < len(simplified); i++ {
        dict[rune(simplified[i])] = rune(traditional[i])
    }
}

func ToTraditional(s string) string {
    var builder strings.Builder
    var ch rune

    for _, r := range s {
        if val, ok := dict[r]; ok {
            ch = val
        } else {
            ch = r
        }
        builder.WriteRune(ch)
    }

    return builder.String()
}

func main() {
    simplified := "床前明月光，疑是地上霜。举头望明月，低头思故乡。 "

    traditional := ToTraditional(simplified)

    fmt.Println(traditional)
}

In the above code, a correspondence table between simplified Chinese characters and traditional Chinese characters is first defined, and then based on the characters in the string For each character, determine whether it has a corresponding traditional Chinese character in the corresponding table, and if so, use the traditional Chinese character to replace the simplified Chinese character.

4. Summary

Traditional Chinese conversion is a relatively common function and is indispensable for applications that need to support multiple languages. As an efficient, easy-to-use, and safe programming language, Golang can well support the implementation of Traditional Chinese conversion function. In practical applications, we can choose to use a third-party library or develop our own traditional Chinese conversion algorithm, and select and use it according to the specific situation.
