<p>简单来说是：</p>
<ol>
<li>初始化了各种目录路径、设置环境变量、初始化各种扩展，设置配置、日志、渲染器、路由等。</li>
<li><code>_bindLocals</code> 方法将数据库中的数据绑定到 <code>locals</code> 对象上。</li>
<li><code>init</code> 方法初始化 <code>Hexo</code>，加载插件和配置。</li>
<li><code>call</code> 方法调用控制台命令。</li>
<li><code>model</code> 方法创建或获取数据库模型。</li>
<li><code>resolvePlugin</code> 和 <code>loadPlugin</code> 方法用于解析和加载插件。</li>
<li><code>load</code> 和 <code>watch</code> 方法加载数据并处理源文件，<code>watch</code> 方法还会设置文件监听。</li>
<li><code>_generate</code> 方法生成静态文件。</li>
<li><code>exit</code> 方法退出程序，执行清理工作。</li>
</ol>
<p>这次，我们来了解一下扩展（<code>extend</code>）。请配合 <a target="_blank" rel="noopener" href="https://hexo.io/zh-cn/api/">官方文档</a> 食用。</p>

<p>这段代码需要在技术层面来讲解。它一个 TypeScript 编译后的 JavaScript 模块，主要用于导出多个类或函数。</p>
<p>用于处理 ES 模块的默认导出的辅助函数：</p>
<figure class="highlight js"><table><tbody><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br></pre></td><td class="code"><pre><span class="line"><span class="keyword">var</span> __importDefault = (<span class="variable language_">this</span> && <span class="variable language_">this</span>.<span class="property">__importDefault</span>) || <span class="keyword">function</span> (<span class="params">mod</span>) {</span><br><span class="line"> <span class="keyword">return</span> (mod && mod.<span class="property">__esModule</span>) ? mod : { <span class="string">"default"</span>: mod };</span><br><span class="line">};</span><br></pre></td></tr></tbody></table></figure>
<p>这行代码将当前模块标记为 ES 模块：</p>
<figure class="highlight js"><table><tbody><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line"><span class="title class_">Object</span>.<span class="title function_">defineProperty</span>(<span class="built_in">exports</span>, <span class="string">"__esModule"</span>, { <span class="attr">value</span>: <span class="literal">true</span> });</span><br></pre></td></tr></tbody></table></figure>
<p>预先声明了所有将要导出的属性：</p>
<figure class="highlight js"><table><tbody><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line"><span class="built_in">exports</span>.<span class="property">Tag</span> = <span class="built_in">exports</span>.<span class="property">Renderer</span> = <span class="built_in">exports</span>.<span class="property">Processor</span> = <span class="built_in">exports</span>.<span class="property">Migrator</span> = <span class="built_in">exports</span>.<span class="property">Injector</span> = <span class="built_in">exports</span>.<span class="property">Highlight</span> = <span class="built_in">exports</span>.<span class="property">Helper</span> = <span class="built_in">exports</span>.<span class="property">Generator</span> = <span class="built_in">exports</span>.<span class="property">Filter</span> = <span class="built_in">exports</span>.<span class="property">Deployer</span> = <span class="built_in">exports</span>.<span class="property">Console</span> = <span class="keyword">void</span> <span class="number">0</span>;</span><br></pre></td></tr></tbody></table></figure>
<p>接下来的代码块都遵循类似的模式，例如：</p>
<figure class="highlight js"><table><tbody><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br></pre></td><td class="code"><pre><span class="line"><span class="keyword">var</span> console_1 = <span class="built_in">require</span>(<span class="string">"./console"</span>);</span><br><span class="line"><span class="title class_">Object</span>.<span class="title function_">defineProperty</span>(<span class="built_in">exports</span>, <span class="string">"Console"</span>, { <span class="attr">enumerable</span>: <span class="literal">true</span>, <span class="attr">get</span>: <span class="keyword">function</span> (<span class="params"></span>) { <span class="keyword">return</span> <span class="title function_">__importDefault</span>(console_1).<span class="property">default</span>; } });</span><br></pre></td></tr></tbody></table></figure>
<p>这些代码从其他文件导入模块，然后将它们重新导出。使用 <code>Object.defineProperty</code> 来定义 <code>getter</code> 函数，这样可以实现延迟加载。</p>
<p>简单而言，这段代码的主要目的是将多个相关的模块集中到一个文件中导出，方便其他部分的代码统一导入这些模块。这种模式在大型项目中很常见，可以简化导入语句并提高代码的组织性。</p>

<p><code>Console</code> 类是 Hexo 的控制台命令管理器。</p>
<p>导入的依赖中，<code>bluebird</code> 已经在 <a href="/posts/5d57.html">上一篇文章</a> 中提过了；<code>abbrev</code> 是用于生成命令别名的包。</p>
<p><a target="_blank" rel="noopener" href="https://github.com/npm/abbrev-js"><img src="https://gh-card.dev/repos/npm/abbrev-js.svg" alt="npm/abbrev-js - GitHub"></a></p>
<p>在构造函数中，<code>store</code> 和 <code>alias</code> 对象被初始化，分别存储命令和别名。</p>
<ul>
<li><code>get</code> 方法通过名称获取控制台插件函数。它会将输入的名称转换为小写，并通过别名查找实际的命令。</li>
<li><code>list</code> 方法返回所有存储的命令。</li>
<li><code>register</code> 方法用于注册新的控制台命令。
<ul>
<li>参数包含：
<ul>
<li><code>name</code>：命令的名称，必须。</li>
<li><code>desc</code>：命令的描述，可选。</li>
<li><code>options</code>：命令的选项，可选。</li>
<li><code>fn</code>：命令的函数，必须（也必须是一个函数）。</li>
</ul>
</li>
<li>使用 <code>bluebird</code> 将命令函数 <code>fn</code> 转换为 Promise，接着将命令存储在 <code>store</code> 对象中，并更新别名。</li>
</ul>
</li>
</ul>
<p><code>Console</code> 类的主要作用是管理 Hexo 的控制台命令。它允许注册新命令，检索已存在的命令，并处理命令别名。</p>
<p>根据官网文档的演示，可以这么用：</p>

<p>关于 <code>args</code> 参数，它是通过 <code>Minimist</code> 库解析命令行参数后得到的对象。</p>
