@fujocoded/expressive-code-caption

Allows adding a caption for a code block that uses expressive code, delineated by --- block fences.

Simple markdown formatting is supported within the caption.

[!IMPORTANT]

1. The code fence must end at the last line before the code block is closed.
2. You should put this plugin as early as possible in the list of plugins to minimize the chance that other plugins will interfere with it and viceversa.

Sample usage

In astro.config.js:

import { pluginCodeCaption } from "@fujocoded/expressive-code-caption";

export default defineConfig({
  // ...
  integrations: [
    starlight({
      expressiveCode: {
        plugins: [pluginCodeCaption()],
      },
    }),
  ],
});

In a markdown file:

Here is a code sample:

```bash
pwd

---
After pressing enter, the `pwd` command will output the current directory
your terminal is in.
---
```

This will add a figcaption element as last child of the rendered terminal with the sentence between the --- fences.
