<content type="html"><![CDATA[<h2 id="写在前面"><a href="#写在前面" class="headerlink" title="写在前面"></a>写在前面</h2><p>大家好，我是程序员七平。<br>这篇文章主要介绍豆包旗下的一款编程助手<code>MarsCode</code>，方便大家对于这款插件有初步的了解。</p><p>本文主要按照以下目录进行介绍和演示：</p><ul><li><p>1、豆包MarsCode是什么？</p></li><li><p>2、在Idea中使用：</p><ul><li>① 代码补全、② 生成单元测试、③ 解释代码、④ 错误修复、⑤ AI问答</li></ul></li><li><p>3、在VsCode中使用：</p><ul><li>① 代码补全、② 生成单元测试、③ 解释代码、④ 错误修复、⑤ AI问答</li></ul></li><li><p>4、豆包在线编辑器 <code>MarsCode IDE</code> 初体验</p></li></ul><h2 id="1、豆包MarsCode是什么？"><a href="#1、豆包MarsCode是什么？" class="headerlink" title="1、豆包MarsCode是什么？"></a>1、豆包MarsCode是什么？</h2><blockquote><p>豆包MarsCode是豆包旗下的编程助手，能够提供<strong>智能补全</strong>、<strong>智能预测</strong>、<strong>智能问答</strong>等能力。</p></blockquote><p>MarsCode的功能简要如下，后面我会逐项进行操作演示：</p><p><strong>① 代码补全</strong>、<strong>② 生成单元测试</strong>、<strong>③ 解释代码</strong> 、<strong>④ 错误修复</strong>、<strong>⑤ AI问答</strong></p><ul><li>官网地址：<a href="https://www.marscode.cn/home">https://www.marscode.cn/home</a>；</li></ul><h2 id="2、豆包MarsCode怎么用？"><a href="#2、豆包MarsCode怎么用？" class="headerlink" title="2、豆包MarsCode怎么用？"></a>2、豆包MarsCode怎么用？</h2><p>从官网的介绍看到，MarsCode支持超过100种语言，并且兼容VSCode和JetBrains IDE。</p><p>对于我来说，最关注的IDE就是IDEA和VS Code，能够在这两个编辑器中使用就已经很好了。</p><p>先了解一下快捷键，快捷键说明官方文档：<a href="https://docs.marscode.cn/docs/extension-keyboard-shortcuts">https://docs.marscode.cn/docs/extension-keyboard-shortcuts</a></p><ul><li>【快捷键】打开侧边 AI 对话框：Windows下快捷键：Ctrl + U；</li><li>【快捷命令】输入<code>#</code>可以选择上下文，有3个选项，<strong>我觉得这个功能后续应该会有更大的作用</strong>，类似于<code>Cursor</code>的<code>CodeBase</code>：<ul><li>添加代码块作为上下文；</li><li>添加文件作为上下文；</li><li>添加工作区代码作为上下文；（这个比较强大）</li></ul></li></ul><p>接下来，通过具体的操作，来看看在这两个编辑器中怎么使用。</p><h3 id="2-1-在-IntelliJ-IDEA中使用："><a href="#2-1-在-IntelliJ-IDEA中使用：" class="headerlink" title="2.1 在 IntelliJ IDEA中使用："></a>2.1 在 IntelliJ IDEA中使用：</h3><h4 id="2-1-1-安装插件"><a href="#2-1-1-安装插件" class="headerlink" title="2.1.1 安装插件"></a>2.1.1 安装插件</h4><p>在IDEA的“setting”->“plugins”->”Marketplace”中搜索“豆包”或者“MarsCode”进行插件安装，完成后重启并登录。</p><p><img src="/images/posts/ai/20241215/20_IDEA%E5%AE%89%E8%A3%85%E8%B1%86%E5%8C%85MarsCode%E6%8F%92%E4%BB%B6.png"></p><p>这里我拉取了<code>ruoyi 前后端分离版本</code>的代码进行的操作和演示，我们一起来看看吧（很详细）。</p><h4 id="2-1-2-代码补全-功能演示【应用建议代码快捷键：Tab键】"><a href="#2-1-2-代码补全-功能演示【应用建议代码快捷键：Tab键】" class="headerlink" title="2.1.2 代码补全-功能演示【应用建议代码快捷键：Tab键】"></a>2.1.2 代码补全-功能演示【应用建议代码快捷键：Tab键】</h4><p>1）正常编写代码，会出现对应代码建议，按下<code>Tab</code>键即可应用这部分建议代码，写代码方便了不少：</p><p><img src="/images/posts/ai/20241215/24_IDEA%E4%BB%A3%E7%A0%81%E8%A1%A5%E5%85%A8.png"></p><p>2）代码自动生成（选中代码文件点击”插入”图标按钮自动插入代码，或者是点击“复制”图标按钮手动粘贴）：</p><p><img src="/images/posts/ai/20241215/22_IDEA%E9%98%85%E8%AF%BB%E6%95%B4%E4%B8%AA%E5%B7%A5%E7%A8%8B%E5%B9%B6%E7%94%9F%E6%88%90%E6%8E%A5%E5%8F%A3%E6%97%A5%E5%BF%97%E7%9A%84%E5%B7%AE%E5%A2%9E%E5%88%A0%E6%94%B9%E5%8A%9F%E8%83%BD.png"></p><h4 id="2-1-3-生成单元测试【对话框命令：-test】"><a href="#2-1-3-生成单元测试【对话框命令：-test】" class="headerlink" title="2.1.3 生成单元测试【对话框命令：/test】"></a>2.1.3 生成单元测试【对话框命令：/test】</h4><p>选中代码，在AI对话框，输入<code>/test</code>直接回车，会针对选中的代码有完整的用例代码生成，直接点击创建文件按钮并保存到对应目录下就行：</p><p><img src="/images/posts/ai/20241215/25_IDEA%E7%94%9F%E6%88%90%E5%8D%95%E5%85%83%E6%B5%8B%E8%AF%95%E7%94%A8%E4%BE%8B.png"></p><p>或者结合IDEA快捷键（<code>Ctrl</code>+<code>Shift</code>+<code>T</code>），让IDEA自动创建测试用例的文件，再点击MarsCode生成测试用例的代码块右上角的“插入”图标按钮进行代码的插入，是不是很省事？</p><h4 id="2-1-4-解释代码"><a href="#2-1-4-解释代码" class="headerlink" title="2.1.4 解释代码"></a>2.1.4 解释代码</h4><h5 id="1-解释整个工作区代码【对话框输入-选择Workspace】（比较强大）"><a href="#1-解释整个工作区代码【对话框输入-选择Workspace】（比较强大）" class="headerlink" title="1) 解释整个工作区代码【对话框输入#选择Workspace】（比较强大）"></a>1) 解释整个工作区代码【对话框输入<code>#</code>选择<code>Workspace</code>】（比较强大）</h5><p>在对话框输入<code># </code>选择<code>Workspace</code>，可以选中整个工作区项目文件，通过对话框要求解释代码，MarsCode会扫描整个工作区的所有代码文件并给出解释，<strong>个人认为，这个比较强大，直接解释整个项目</strong>，示例：</p><p><img src="/images/posts/ai/20241215/21_IDEA%E8%A7%A3%E9%87%8A%E6%95%B4%E4%B8%AA%E9%A1%B9%E7%9B%AE.png"></p><h5 id="2-解释选中代码【对话框命令：-explain】"><a href="#2-解释选中代码【对话框命令：-explain】" class="headerlink" title="2) 解释选中代码【对话框命令：/explain】"></a>2) 解释选中代码【对话框命令：/explain】</h5><p>选中代码后，输入上述对话框命令，解释代码并给出改进建议和修复后的代码：</p><p><img src="/images/posts/ai/20241215/21_IDEA%E8%A7%A3%E9%87%8A%E9%80%89%E4%B8%AD%E4%BB%A3%E7%A0%81%E5%B9%B6%E7%BB%99%E5%87%BA%E6%94%B9%E8%BF%9B%E5%BB%BA%E8%AE%AE%E5%92%8C%E7%A4%BA%E4%BE%8B%E4%BB%A3%E7%A0%81.png"></p><h5 id="3-为选中代码添加更详细的注释【对话框命令：-doc】"><a href="#3-为选中代码添加更详细的注释【对话框命令：-doc】" class="headerlink" title="3) 为选中代码添加更详细的注释【对话框命令：/doc】"></a>3) 为选中代码添加更详细的注释【对话框命令：/doc】</h5><p>选中代码后，输入上述对话框命令，会给原有代码添加方法级注释和行级注释。左边原始代码，右边是MarsCode生成的，<strong>不喜欢写注释又不得不写的同学的福音</strong>：</p><p><img src="/images/posts/ai/20241215/21_IDEA%E4%B8%BA%E9%80%89%E4%B8%AD%E4%BB%A3%E7%A0%81%E6%B7%BB%E5%8A%A0%E6%96%B9%E6%B3%95%E7%BA%A7%E6%B3%A8%E9%87%8A%E5%92%8C%E8%A1%8C%E7%BA%A7%E6%B3%A8%E9%87%8A.png"></p><h4 id="2-1-5-错误修复【对话框命令：-fix】"><a href="#2-1-5-错误修复【对话框命令：-fix】" class="headerlink" title="2.1.5 错误修复【对话框命令：/fix】"></a>2.1.5 错误修复【对话框命令：/fix】</h4><p>选中需要修复的代码，在AI对话框，输入<code>/fix</code>直接回车，会帮助我们修复代码，并支持插入到代码文件中，查看示例：</p><p><img src="/images/posts/ai/20241215/27_IDEA%E9%94%99%E8%AF%AF%E4%BF%AE%E5%A4%8D.png"></p><p><img

在VsCode中使用</h3><p>打开项目，这里我使用<code>ruoyi-vue</code>的前端代码。</p><h4 id="2-2-1-安装插件"><a href="#2-2-1-安装插件" class="headerlink" title="2.2.1 安装插件"></a>2.2.1 安装插件</h4><p>点击官网的【立即获取编程助手】，然后点击【立即安装】会自动打开VSCode IDE，下载插件后点击登录（支持掘金登录），如下图：</p><p><img src="/images/posts/ai/20241215/02_VSCode%E4%B8%AD%E5%AE%89%E8%A3%85.png"></p><p>或者直接在VSCode的【扩展】中搜索”豆包MarsCode“自行安装，然后登录也可以。</p><h4 id="2-2-2-代码补全"><a href="#2-2-2-代码补全" class="headerlink" title="2.2.2 代码补全"></a>2.2.2 代码补全</h4><p>与IDEA操作相同</p><h4 id="2-2-3-生成单元测试"><a href="#2-2-3-生成单元测试" class="headerlink" title="2.2.3 生成单元测试"></a>2.2.3

id="2-解释选中代码："><a href="#2-解释选中代码：" class="headerlink" title="2) 解释选中代码："></a>2) 解释选中代码：</h5><p>选中代码之后，在AI对话框中输入“/explain”或者点击解释代码，可以看到对代码的解释：</p><p><img

src="/images/posts/ai/20241215/10_MarsCodeIDE.png"></p><p>支持<code>手机号</code>、<code>掘金</code>、<code>抖音方式登录</code>：</p><p><img src="/images/posts/ai/20241215/11_MarsCodeIDE%E7%99%BB%E5%BD%95.png"></p><h4 id="1）通过选定模板来创建项目"><a href="#1）通过选定模板来创建项目" class="headerlink" title="1）通过选定模板来创建项目"></a>1）通过选定模板来创建项目</h4><p><img src="/images/posts/ai/20241215/12_01%E5%88%9B%E5%BB%BA%E9%A1%B9%E7%9B%AE.png"></p><p>我通过vue模板创建了一个项目，直接点击上方的<code>Run</code>按钮可以看到自动安装依赖并启动预览，<strong>无需本地下载依赖，速度也很快、无需切换浏览器</strong>，效果看下图：</p><p><img src="/images/posts/ai/20241215/15_%E5%9C%A8%E7%BA%BF%E8%BF%90%E8%A1%8C%E5%B9%B6%E9%A2%84%E8%A7%88.png"></p><h4 id="2）支持从Github导入项目"><a href="#2）支持从Github导入项目" class="headerlink" title="2）支持从Github导入项目"></a>2）支持从Github导入项目</h4><p>通过Github授权之后可以访问所有代码仓库，我这里选择的是前一段时间开发的定时提醒休息的客户端软件。</p><p><img src="/images/posts/ai/20241215/12_%E4%BB%8EGithub%E4%B8%AD%E5%AF%BC%E5%85%A5%E9%A1%B9%E7%9B%AE.png"></p><p><img src="/images/posts/ai/20241215/13_%E4%B8%BB%E7%95%8C%E9%9D%A2.png"></p><p>不过有一个限制，就是没法像前面两个插件一样扫描整个项目代码，应该是权限问题。</p><p>个人感受：<code>MarsCode IDE</code>这个在线编辑器 目前支持比较好的就是<strong>前端项目</strong>，很快就能出效果。</p><p>对于我来说，能在IDEA和VSCode中使用就已经很满意了，期待豆包MarsCode后续越来越强大！</p><h3 id="总结："><a href="#总结：" class="headerlink" title="总结："></a>总结：</h3><p><strong>①

错误修复</strong>：帮助我们发现代码中的问题并说明怎么改；</p><p><strong>⑤ AI问答</strong>：省去了频繁切换IDE和去浏览器检索的时间，直接在IDE中进行提问，集中精力、更好的禅模式！</p><p>我认为：AI，对于程序员来说是能力的拓展和效率的提升。拥抱AI、主动适应AI带来的改变，主动找到在AI时代我们新的定位，积极探索更多AI的应用场景，成为AI赋能的超级程序员（超级个体），这对程序员来说得天独厚！</p>]]></content>

项目刚刚起步，主要用于容器化和镜像管理。</li><li><code>docker-compose</code> 作为一个独立工具（由 Python 编写）于 2014 年发布。</li></ul></li><li><p><strong>Docker 1.13.1（2017 年 2 月）</strong></p><ul><li>引入 <code>docker stack</code> 命令，支持基于 Compose 文件的服务编排（Swarm 模式）。</li><li>支持 Compose v3 文件格式，优化多容器服务定义与 Swarm 集成。</li></ul></li><li><p><strong>Docker Engine 17.x（2017）（<code>Community</code> 和 <code>Enterprise</code> 分离）</strong></p><ul><li><code>Docker Engine</code> 被分为 <code>Docker CE</code>（社区版）和 <code>Docker EE</code>（企业版）。</li><li>仍然使用独立的 <code>docker-compose</code>，其功能逐步完善，支持更多的 Docker 功能，如网络和卷。</li><li><code>Compose v1</code> 成为大规模生产环境的实际标准。</li></ul></li><li><p><strong>Docker Engine 20.10（2020 年 12 月，支持 Compose v2 的起点）</strong></p><ul><li>引入了对 <strong>Compose v2</strong> 的支持（<code>docker-compose</code>v1继续保留，但逐渐转向 v2。），这是一个基于 Go 的重写版本，作为 Docker CLI 的插件运行。</li><li>v2 的主要改进包括性能优化、原生支持 Kubernetes，以及改用 <code>docker compose</code> 命令（无破折号）。</li><li>用户开始过渡到使用 <code>docker compose</code>。</li></ul></li><li><p><strong>Docker Desktop 4.4 / Docker Engine 20.10.13（2021 年底）</strong></p><ul><li>在 Docker Desktop 中，Compose v2 成为默认工具。</li><li>官方明确推荐使用 <code>docker compose</code> 命令。</li><li>在 Docker Desktop 和 Linux 系统中，<code>docker-compose-plugin</code> 替代了 <code>docker-compose</code>。<ul><li>可以通过 <code>docker compose version</code> 验证是否使用了 v2。</li></ul></li></ul></li><li><p><strong>Docker Engine 24.0（2023 年 5 月）</strong></p><ul><li>完全移除了对 <code>docker-compose</code>（v1）的支持。</li><li>Compose v2 成为唯一选项，并直接作为 Docker 的插件运行。</li><li>不再包含独立的
