建议使用Java创建翻译器

下面是一个示例实现:

import java.io.*;
import java.util.*;

public class Translator {

    public enum Language {
        EN, ES
    }

    private static final String TRANSLATION_TEMPLATE = "translation_%s_%s.properties";
    private final Properties translations = new Properties();

    public Translator(Language from, Language to) {
        String translationFile = String.format(TRANSLATION_TEMPLATE, from, to);
        try (InputStream is = getClass().getResourceAsStream(translationFile)) {
            translations.load(is);
        } catch (final IOException e) {
            throw new RuntimeException("Could not read: " + translationFile, e);
        }
    }

    private String[] translate(String text) {
        String[] source = normalizeText(text);
        List<String> translation = new ArrayList<>();
        for (String sourceWord : source) {
            translation.add(translateWord(sourceWord));
        }
        return translation.toArray(new String[source.length]);
    }

    private String translateWord(String sourceWord) {
        Object value = translations.get(sourceWord);
        String translatedWord;
        if (value != null) {
            translatedWord = String.valueOf(value);
        }
        else {
            // if no translation is found, add the source word with a question mark
            translatedWord = sourceWord + "?";
        }
        return translatedWord;
    }

    private String[] normalizeText(String text) {
        String alphaText = text.replaceAll("[^A-Za-z]", " ");
        return alphaText.split("\\s+");
    }

    public static void main(final String[] args) {
        final Translator translator = new Translator(Language.EN, Language.ES);
        System.out.println(Arrays.toString(translator.translate("hello world!")));
    }
}

然后在类路径(例如src/main/resources)上放置一个名为“translation_EN_ES.properties”的文件:

hello=holla
world=mundo

如果你事先知道所有的单词,你可以很容易地创建一个Regex Trie。
然后在运行时,编译正则表达式一次。那你就可以走了。

要创建正则表达式,请下载并安装RegexFormat 5 here .

从主菜单中,选择 工具->Regex的字符串-三元树
将列表粘贴到输入框中,然后按 生成 按钮
它抛出一个完整的正则表达式Trie,它的速度与任何哈希查找一样快。

将该对话框中的压缩输出复制到 Rxform格式 选项卡(mdi)窗口。
右键单击窗口以获取上下文菜单,选择 其他实用程序->换行符
将其设置为大约60个字符的宽度,然后按ok。

下一步按 C++ 按钮,打开 MegaString(MegaString)
对话单击生成C样式字符串 1类线 按OK。
将结果复制并粘贴到Java源代码中。

在“全部替换为”回调中使用正则表达式。
在回调中,将匹配项用作哈希表的键,以返回
要替换的翻译。

它很简单,一次通过,噢,太快了。

有关工具的更极端示例,请参见 this 13万单词词典的正则表达式。
