Is it possible to pass arguments to remark plugins?

#

Hi @half current. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

#

Yes, it is possible to pass arguments to remark plugins in Astro. You can do this by including the arguments in an array along with the plugin function in your configuration file. Here is an example from the Astro documentation:

import { defineConfig } from 'astro/config';
import remarkToc from 'remark-toc';
import { rehypeAccessibleEmojis } from 'rehype-accessible-emojis';

export default defineConfig({
  markdown: {
    remarkPlugins: [
      remarkToc
    ],
    rehypePlugins: [
      rehypeAccessibleEmojis
    ],
  },
});

In this example, if remarkToc or rehypeAccessibleEmojis accepted arguments, you could pass them like this:

remarkPlugins: [
  [remarkToc, { /* options here */ }]
],
rehypePlugins: [
  [rehypeAccessibleEmojis, { /* options here */ }]
],

Please refer to each plugin's own README for specific instructions on what options are available and how to use them.

@sacred trellis is extenddefaultplugins available in the current version of Astro, or has it been deprecated?

sacred trellisBOT
#

Let me check the knowledge base for you. One moment! :books:

#

The extendDefaultPlugins configuration option has been removed in Astro v2.0. This change was made because its behavior is now the default. Applying remark and rehype plugins in your Markdown configuration no longer disables Astro’s default plugins. GitHub-Flavored Markdown and Smartypants are now applied whether or not custom remarkPlugins or rehypePlugins are configured.

If you were using extendDefaultPlugins in your configuration, you should remove it. This is now Astro’s default behavior in v2.0, and you can delete this line without any replacement.

Here's an example of how your configuration might look:

import { defineConfig } from 'astro/config';
export default defineConfig({ markdown: { extendDefaultPlugins, }});

In Astro v2.0, you can control each of Astro’s built-in default Markdown plugins individually with separate Boolean options. These are enabled by default and can be set to false independently.

  • markdown.gfm: false disables GitHub-Flavored Markdown
  • markdown.smartypants: false disables SmartyPants

Here's an example of how your configuration might look:

import { defineConfig } from 'astro/config';
export default defineConfig({ markdown: { extendDefaultPlugins: false, smartypants: false, gfm: false, }});

@sacred trellis how do I configure rehype to use rehype-mathjax with common HTML output. In other words, how do I use rehype-mathjax/chtml with rehype?

sacred trellisBOT
#

Let me check the knowledge base for you. One moment! :books:

#

To configure rehype to use rehype-mathjax with common HTML output, you need to import the rehype-mathjax/chtml module and add it to the rehypePlugins array in your Astro configuration. Here's an example of how you might do this:

import { defineConfig } from 'astro/config';
import rehypeMathjax from 'rehype-mathjax/chtml';

export default defineConfig({
  markdown: {
    rehypePlugins: [
      rehypeMathjax
    ],
  },
});

In this example, rehype-mathjax/chtml is imported and added to the rehypePlugins array in the Astro configuration. This tells Astro to use rehype-mathjax when processing your Markdown files, and to output common HTML.

Please note that you need to install rehype-mathjax in your project before you can use it. You can do this with npm:

npm install rehype-mathjax

Or with yarn:

yarn add rehype-mathjax

To add the KaTeX stylesheet to every page of your Astro site, you can use a layout component. Layout components in Astro are special components that allow you to wrap your pages with common elements, such as headers, footers, or in this case, a stylesheet link in the head of the document.

Here's how you can do it:

  1. Create a new Astro component in your project. You can name it Layout.astro and place it in your src/components directory.

  2. In Layout.astro, add the following code:

---
import { Astro } from 'astro/components';
---
<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>My Astro Site</title>
  <link rel="stylesheet" href="<https://cdn.jsdelivr.net/npm/katex@0.16.9/dist/katex.css"> integrity="sha384-OH8qNTHoMMVNVcKdKewlipV4SErXqccxxlg6HC9Cwjr5oZu2AdBej1TndeCirael" crossorigin="anonymous">
</head>
<body>
  <Astro.Root>{Astro.props.children}</Astro.Root>
</body>
</html>
  1. Now, you can use this layout in your pages. For example, in src/pages/index.astro, you can do:
---
import Layout from '../components/Layout.astro';
---
<Layout>
  <!-- Your page content here -->
</Layout>

This will wrap your page content with the Layout component, which includes the KaTeX stylesheet link in the head of the document. Repeat this for every page where you want to include the KaTeX stylesheet.

@sacred trellis How do I edit the layout components when I'm using the Starlight theme?

#

<@&1095491216776380548> How do I edit the layout components when I'm using the Starlight theme?

#

@sacred trellis How do I edit the layout components when I'm using the Starlight theme?

sacred trellisBOT
#

Let me check the knowledge base for you. One moment! :books:

#

To edit the layout components when using the Starlight theme in Astro, you would need to locate the layout components in your project's directory and make the necessary changes. Layout components in Astro are usually located in the src/layouts or src/components directory.

Here's a general guide on how to do it:

  1. Open your Astro project in your code editor.

  2. Navigate to the src/layouts or src/components directory.

  3. Open the layout component file you want to edit. The file will have a .astro extension.

  4. Make the necessary changes in the file and save it.

Please note that the exact location and name of the layout components might vary depending on how your project is structured. If you're using a specific theme, the layout components might be located in a different directory or have different names.

If you want to add a stylesheet link to the head of every page, you can do it in the layout component. Here's an example:

<html lang="en">
<head>
  <!-- Add your stylesheet link here -->
  <link rel="stylesheet" href="<https://cdn.jsdelivr.net/npm/katex@0.16.9/dist/katex.css"> integrity="sha384-OH8qNTHoMMVNVcKdKewlipV4SErXqccxxlg6HC9Cwjr5oZu2AdBej1TndeCirael" crossorigin="anonymous">
</head>
<body>
  <slot/>
</body>
</html>

In this example, the slot component is used to render the content of the page. The stylesheet link is added in the head of the document.

How do I add an external stylesheet to an MDX page? @sacred trellis

sacred trellisBOT
#

Let me check the knowledge base for you. One moment! :books:

#

To add an external stylesheet to an MDX page in Astro, you can use the <link> element to load the stylesheet. This should be an absolute URL path to a CSS file located in your /public directory, or a URL to an external website.

Here's an example of how you can do it:

---
layout: ../layouts/MainLayout.astro
---
<head>
  <link rel="stylesheet" href="<https://cdn.jsdelivr.net/npm/prismjs@1.24.1/themes/prism-tomorrow.css"> />
</head>

# Your MDX Content Here

In this example, the link tag is added in the head of the document. The href attribute is set to the URL of the external stylesheet.

Please note that relative <link> href values are not supported. The URL should be an absolute path to a CSS file located in your /public directory, or a URL to an external website.

Also, keep in mind that this approach uses the public/ directory, it skips the normal CSS processing, bundling, and optimizations that are provided by Astro. If you need these transformations, you should import the stylesheet instead.
