主题已完成 `Halo 2.0` 适配，2.x 的主题不在当前仓库维护，详见：https://github.com/nineya/halo-theme-dream2.0 ## 一、预览 ![玖涯博客](https://cdn.jsdelivr.net/gh/nineya/halo-theme-dream@master/preview.png) 预览：[主题预览](https://github.com/nineya/halo-theme-dream/discussions/72) > 如果你有计划长期使用 `Dream` 主题，也来[这里](https://github.com/nineya/halo-theme-dream/discussions/72)留下你的博客链接吧。 ## 二、说明 梦之城，童话梦境，动漫类型博客主题。 关于主题使用上的一些问题可以参见 [主题使用手册-基础篇](https://blog.nineya.com/archives/94.html) 如有疑问，欢迎加入 Dream 主题交流群：638168592 个人博客交流，友链交换，欢迎加入 个人博客交流群：582535349 欢迎参与主题开发的一些问题探讨 欢迎关注微信公众号《玖涯菜菜子》，主题版本更新消息与要点说明将在公众号发布。 ![微信公众号](https://blog.nineya.com/upload/2025/03/%E7%8E%96%E6%B6%AF%E5%90%8E%E7%AB%AF%E7%AC%94%E8%AE%B0.png) ## 三、版本适配关系 | 主题版本 | 适配Halo-Plus版本 | 测试用Halo-Plus版本 | |----------|---------------|----------------| | xx-2.3.1 | 1.0.0 | 1.0.0 | | 3.0.0 | 1.0.1 | 1.0.1 | | 3.0.1 | 1.0.2 | 1.0.2 | 当前仓库为适配 `Halo-Plus` 的仓库，与 `Halo` 官方的博客系统不兼容。 - 兼容 `Halo 1.x` 的分支（存档，不再维护）：https://github.com/nineya/halo-theme-dream/tree/halo - 兼容 `Haki 2.x` 的分支（维护中）：https://github.com/nineya/halo-theme-dream2.0 ## 四、安装 & 更新 ### 4.1 安装包安装 & 更新 1. 进入主题 `Release` 界面：https://github.com/nineya/halo-theme-dream/releases 下载主题压缩包 `halo-theme-dream.zip` 压缩包文件； 2. 进入博客后台管理 `外观->主题->安装->本地上传`，选择下载的 `halo-theme-dream.zip` 安装包进行上传； 3. 等待安装完成； 4. 更新主题时同样前往主题 `Release` 界面下载主题安装包，然后通过 `外观->主题->Dream->更多->从主题包更新` 方法上传安装包进行更新。 ### 4.2 在线安装 & 更新 1. 复制主题仓库地址 `https://github.com/nineya/halo-theme-dream.git` 2. 进入博客后台管理 `外观->主题->安装->远程下载`，黏贴仓库地址进行安装； 3. 等待安装完成； 4. 在线更新主题时，通过 `外观->主题->Dream->更多->在线更新` 方法进行更新。 > 在线安装 & 更新的方式不推荐： > > 1. 因为由于 `GitHub` 的网络问题，很大几率会安装& 更新失败； > 2. 主题是经过源码编译的，直接从仓库下载包含了主题的源码以及开发所需的相关文件，这些文件并不是安装主题所需要的。 ## 五、参与主题开发 > 推荐使用 IDEA 进行主题开发，能够比较好的支持 FreeMarker。 1. 开发环境准备 - 安装 `nodejs` 版本需要在 `15+`； - 主题目录下执行 `npm i` 安装依赖； 2. npm 命令 - `npm run build` 执行主题打包操作，主题将被打包为压缩包文件存放在 `dist/` 目录下，同时 `source` 目录下的文件也将被更新。 - `npm run build --devel` 开发模式进行主题打包，`js` 和 `css` 不会被做压缩和混淆处理，方便排查问题。 - `npm run cdn --tag=$version` 创建 `FreeCDN` 清单文件，必须指定 `tag` 参数，值为本地代码将发布到 `GitHub` 仓库的版本标签。 - `npm run release --tag=$version` 发布模式执行主题打包操作，将自动更新主题中的版本号，并使用这个版本标签重新创建 `FreeCDN` 清单文件。 ## 六、打赏项目 感谢您对本项目的喜爱，您的打赏是对本项目最好的支持！ ![打赏项目](https://blog.nineya.com/upload/2022/08/funding.png) ================================================ FILE: archives.ftl ================================================ <#include "template/layout.ftl"> <@layout title="归档 - ${blog_title!}" canonical="${archives_url!}"> <#if (archives)?? && archives?size gt 0> <#list archives as archive>

For details on how to configure auto-render extension, refer to [the documentation](https://katex.org/docs/autorender.html). ### API Call `katex.render` to render a TeX expression directly into a DOM element. For example: ```js katex.render("c = \\pm\\sqrt{a^2 + b^2}", element, { throwOnError: false }); ``` Call `katex.renderToString` to generate an HTML string of the rendered math, e.g., for server-side rendering. For example: ```js var html = katex.renderToString("c = \\pm\\sqrt{a^2 + b^2}", { throwOnError: false }); // '...' ``` Make sure to include the CSS and font files in both cases. If you are doing all rendering on the server, there is no need to include the JavaScript on the client. The examples above use the `throwOnError: false` option, which renders invalid inputs as the TeX source code in red (by default), with the error message as hover text. For other available options, see the [API documentation](https://katex.org/docs/api.html), [options documentation](https://katex.org/docs/options.html), and [handling errors documentation](https://katex.org/docs/error.html). ## Demo and Documentation Learn more about using KaTeX [on the website](https://katex.org)! ## Contributing See [CONTRIBUTING.md](CONTRIBUTING.md) ## License KaTeX is licensed under the [MIT License](http://opensource.org/licenses/MIT). ================================================ FILE: source/lib/katex@0.12.0/contrib/auto-render.js ================================================ (function webpackUniversalModuleDefinition(root, factory) { if(typeof exports === 'object' && typeof module === 'object') module.exports = factory(require("katex")); else if(typeof define === 'function' && define.amd) define(["katex"], factory); else if(typeof exports === 'object') exports["renderMathInElement"] = factory(require("katex")); else root["renderMathInElement"] = factory(root["katex"]); })((typeof self !== 'undefined' ?

That left-over shaft is not shown. // Instead, it is sliced off because the span's CSS has overflow: hidden. // Thus, the reader sees an arrow that matches the subject matter width // without distortion. // Some functions, such as \cancel, need to vary their aspect ratio. These // functions do not get the overflow SVG treatment. // Second Brush Stroke // Low resolution monitors struggle to display images in fine detail. // So browsers apply anti-aliasing. A long straight arrow shaft therefore // will sometimes appear as if it has a blurred edge. // To mitigate this, these SVG files contain a second "brush-stroke" on the // arrow shafts. That is, a second long thin rectangular SVG path has been // written directly on top of each arrow shaft. This reinforcement causes // some of the screen pixels to display as black instead of the anti-aliased // gray pixel that a single path would generate. So we get arrow shafts // whose edges appear to be sharper. // In the katexImagesData object just below, the dimensions all // correspond to path geometry inside the relevant SVG. // For example, \overrightarrow uses the same arrowhead as glyph U+2192 // from the KaTeX Main font.

That left-over shaft is not shown. // Instead, it is sliced off because the span's CSS has overflow: hidden. // Thus, the reader sees an arrow that matches the subject matter width // without distortion. // Some functions, such as \cancel, need to vary their aspect ratio. These // functions do not get the overflow SVG treatment. // Second Brush Stroke // Low resolution monitors struggle to display images in fine detail. // So browsers apply anti-aliasing. A long straight arrow shaft therefore // will sometimes appear as if it has a blurred edge. // To mitigate this, these SVG files contain a second "brush-stroke" on the // arrow shafts. That is, a second long thin rectangular SVG path has been // written directly on top of each arrow shaft. This reinforcement causes // some of the screen pixels to display as black instead of the anti-aliased // gray pixel that a single path would generate. So we get arrow shafts // whose edges appear to be sharper. // In the katexImagesData object just below, the dimensions all // correspond to path geometry inside the relevant SVG. // For example, \overrightarrow uses the same arrowhead as glyph U+2192 // from the KaTeX Main font.

The lexer (found in Lexer.js, stored at * this.gullet.lexer) also supports pulling out tokens at arbitrary places. When * individual tokens are needed at a position, the lexer is called to pull out a * token, which is then used. * * The parser has a property called "mode" indicating the mode that * the parser is currently in. Currently it has to be one of "math" or * "text", which denotes whether the current environment is a math-y * one or a text-y one (e.g. inside \text). Currently, this serves to * limit the functions which can be used in text mode. * * The main functions then return an object which contains the useful data that * was parsed at its given point, and a new position at the end of the parsed * data.
