How can mathematical formulas and flowcharts be displayed correctly in AnQiCMS documents?

As a professional deeply familiar with the operation of AnQiCMS (AnQiCMS), I will give you a detailed explanation of how to correctly display mathematical formulas and flowcharts in AnQiCMS.AnQi CMS has added support for Markdown editors in the new version, which greatly enriches the expression form of content creation, making it possible to insert complex mathematical formulas and intuitive flowcharts in articles.However, to perfectly present these special contents on the front-end page, some additional configuration steps are required, mainly relying on external JavaScript libraries for rendering.

In order to be able to use the Markdown editor to create mathematical formulas and flowcharts, you first need to enable the Markdown editor feature in the Anqi CMS backend.You can navigate to the "Global Settings" under the "Content Settings" option, where you can find and enable the Markdown editor.After enabling, you can choose to use Markdown format for content creation when creating or editing documents.

In Markdown editor, inserted mathematical formulas and flowcharts are recognized as specific syntax, but the browser itself cannot directly render these complex structures.Therefore, we need to introduce the corresponding third-party JavaScript library to parse and beautify the content.These libraries are typically provided through content delivery networks (CDN) for fast loading and stable operation.You need to edit the website template file, usually namedbase.htmlfile, and include these scripts in the header area of the page.

For the correct display of mathematical formulas, we recommend using the MathJax library.MathJax can render mathematical expressions in LaTeX, MathML, or AsciiMath formats as high-quality images or HTML elements, ensuring that formulas are presented clearly and accurately on various devices and browsers.In order to enable MathJax on your AnQiCMS website, pleasebase.htmlAdd the following script reference in the header area of the file

<script id="MathJax-script" async src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-mml-chtml.js"></script>

This script will asynchronously load the MathJax library and automatically find and render the mathematical formulas you have written in Markdown. In Markdown, you can use$$...$$or$...$Write a mathematical formula, for example:$$E=mc^2$$.

Similarly, for the drawing and display of flowcharts, Mermaid is a very powerful JavaScript library.Mermaid allows you to use simple text syntax to define various charts, including flowcharts, sequence diagrams, Gantt charts, and so on.It can convert these text definitions into SVG graphics, thereby achieving cross-platform and responsive chart display.You need to enable the Mermaid flowchart feature in AnQiCMS,base.htmlAdd the following JavaScript code to the header area of the file:

<script type="module">
    import mermaid from 'https://cdn.jsdelivr.net/npm/mermaid@10/dist/mermaid.esm.min.mjs';
    mermaid.initialize({ startOnLoad: true });
</script>

This script will import the Mermaid library in a modular way and initialize it to automatically search and render flowcharts when the page loads. In Markdown, you can use specific Mermaid syntax blocks to define flowcharts, such as:

```mermaid
graph TD;
    A-->B;
    A-->C;
    B-->D;
    C-->D;

此外，为了让您的Markdown内容拥有更一致和美观的样式，尤其是在显示代码块和表格时，您可以考虑引入GitHub风格的Markdown CSS。这并非强制，但能显著提升阅读体验。您可以在`base.html`文件的头部添加如下样式表链接：

```html
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/github-markdown-css/5.2.0/github-markdown.min.css" crossorigin="anonymous" referrerpolicy="no-referrer" />

After completing these configurations, you simply need to write mathematical formulas and flowcharts according to the standard syntax of MathJax and Mermaid in the AnQi CMS Markdown editor, and they will be correctly parsed and rendered on the front-end page, greatly enhancing the professionalism and readability of the content.Before releasing the document, it is recommended that you create a test document containing mathematical formulas and flowcharts to verify that all configurations are effective.

Frequently Asked Questions (FAQ)

1. Why did the math formula and flow chart still not display after I configured according to the steps?

First, make sure you have enabled the Markdown editor in the "Global Settings" -> "Content Settings" of the AnQiCMS backend. Second, check carefully.base.htmlThe CDN link included in the file is complete and correct, and is located in the standard.<head>In the tag).Network connection issues may also cause CDN resource loading failures. You can try changing the network environment or checking the browser console for error messages.In addition, please confirm that the mathematical formula and flowchart syntax you are using in the Markdown editor is consistent with MathJax (such as LaTeX) and Mermaid (such asgraph TD.

2. Can I deploy MathJax and Mermaid libraries on my own server without using a CDN?

Yes, you can choose to download the files of the MathJax and Mermaid libraries to your server and modifybase.htmlThe script reference path points to your local file. For example, to reference a scriptsrcThe property to/public/static/js/mathjax/tex-mml-chtml.jsThe benefits of doing so include avoiding dependence on external CDNs, improving the autonomy of the website, and possibly providing faster loading speeds in certain network environments.But, you need to manage the updates and maintenance of these libraries yourself.

3. What are the recommended syntaxes for writing mathematical formulas and flowcharts in Markdown?

For mathematical formulas, the most commonly used is LaTeX syntax. Inline formulas can be enclosed using$your formula$, and independent formula blocks can be enclosed using$$your formula$$. For example:$a^2 + b^2 = c^2$and$$x = \frac{-b \pm \sqrt{b^2-4ac}}{2a}$$.

For flowcharts, Mermaid has its specific text syntax. It ends withmermaid `开始，以`. For example, a simple flowchart can be defined in the following way:

```mermaid
graph LR
    A[开始] --> B{决策?};
    B -- 是 --> C[执行操作];
    B -- 否 --> D[结束];
    C --> D;

You can check the official documentation of MathJax and Mermaid for more detailed and complex syntax examples.
