如何编写一个composer脚本来处理多语言文件

// scripts/LanguageProcessor.php
<?php

class LanguageProcessor
{
    private $langDir;

    public function __construct($langDir = 'lang')
    {
        $this->langDir = $langDir;
    }

    // 检查所有语言文件是否包含相同的键
    public function validate()
    {
        if (!is_dir($this->langDir)) {
            echo "语言目录不存在：{$this->langDir}\n";
            return false;
        }

        $files = glob("{$this->langDir}/*.json");
        if (empty($files)) {
            echo "未找到语言文件。\n";
            return false;
        }

        $base = json_decode(file_get_contents($files[0]), true);
        $baseKeys = array_keys($base);

        foreach ($files as $file) {
            $lang = basename($file, '.json');
            $data = json_decode(file_get_contents($file), true);
            $missing = array_diff($baseKeys, array_keys($data));

            if (!empty($missing)) {
                echo "【{$lang}】缺少键: " . implode(', ', $missing) . "\n";
            }
        }

        echo "验证完成。\n";
        return true;
    }

    // 合并新增键到所有语言文件（可扩展）
    public function sync()
    {
        // 实现同步逻辑：提取所有键，填充空值到其他语言
        echo "正在同步语言文件...\n";
        // 此处可添加合并策略
    }
}

// scripts/process-lang.php
<?php

require_once __DIR__ . '/LanguageProcessor.php';

$processor = new LanguageProcessor('lang');

$action = $argv[1] ?? 'validate';

if ($action === 'sync') {
    $processor->sync();
} else {
    $processor->validate();
}

{
    "scripts": {
        "lang-validate": "php scripts/process-lang.php validate",
        "lang-sync": "php scripts/process-lang.php sync",
        "post-install-cmd": [
            "@lang-validate"
        ],
        "post-update-cmd": [
            "@lang-validate"
        ]
    }
}
