前言

之前写过《自由地给文章添加文章总结》，但是每次添加总结都需要粘贴十多行代码，十分麻烦，这里将代码与butterfly主题进行整合，因此本教程只适合butterfly或butterfly魔改的主题。

开始

首先在主题文件夹下的/layout/includes/新建一个custom文件夹，然后在此文件夹下新建文件ai.pug。

文件内容如下，可根据实际情况进行修改：

.post-ai
    .ai-title
        i.fa-solid.fa-robot
        a.ai-title-left(data-pjax-state='')
            .ai-title-text 文章摘要
            .ai-link
                i.heofont.icon-arrow-right-s-line
        .ai-tag#ai-tag GoodBoyboyGPT
    .ai-explanation(style='display: block;')
        span.ai-typed-text
        .ai-source-text
            span=page.ai
    .ai-suggestions
    .ai-bottom
        .ai-tips 此内容根据文章生成，并经过人工审核，仅用于文章内容的解释与总结

script(src='/js/typed/typed.umd.js',async)
script(src='/js/ai.js',async)

这里的引入的JavaScript有typedjs和一个自定义的aijs，typedjs和aijs引入链接可根据实际情况进行调整。

然后在主题目录下的/source/js新建文件ai.js，内容如下：

1

function checkTyped() {
    if (typeof Typed !== "undefined") {
        var typed = new Typed(".ai-typed-text", {
            stringsElement: ".ai-source-text",
            typeSpeed: 25,
            startDelay: 1000,
            fadeOut: false,
        });
    } else {
        setTimeout(checkTyped, 100);
    }
}
checkTyped();

找到主题目录/layout文件夹下的post.pug文件，找到下面代码，第6行左右：

1
2
if top_img === false
    include includes/header/post-info.pug

在下面添加以下代码，注意缩进格式：

1
2
if page.ai
    include includes/custom/ai.pug

添加完后应该如下面所示：

1
2
3
4
if top_img === false
    include includes/header/post-info.pug
if page.ai
    include includes/custom/ai.pug

然后在主题目录/source/css/_layout下新建文件ai.styl，文件内容如下：
