### Example: Prism.js Integration

Source: https://waline.js.org/en/cookbook/customize/highlighter

An example demonstrating how to integrate Prism.js for code highlighting with Waline. This involves creating a custom highlighter function that utilizes Prism.js to process and return the highlighted code.

```javascript
import Prism from 'prismjs';
import 'prismjs/components/prism-bash'; // Import specific language support
import 'prismjs/components/prism-javascript';

// Assuming Waline is initialized with this custom highlighter
// new Waline({ 
//   el: '#waline', 
//   serverURL: '...', 
//   highlighter: ({ code, lang }) => {
//     const language = Prism.languages[lang] ? lang : 'markup';
//     return Prism.highlight(code, Prism.languages[language], language);
//   }
// });

// Example of the highlighter function structure:
const customHighlighter = ({ code, lang }) => {
  // Check if Prism supports the language, default to markup if not
  const language = Prism.languages[lang] ? lang : 'markup';
  // Highlight the code using Prism.js
  return Prism.highlight(code, Prism.languages[language], language);
};
```

### Waline Hook Plugin Example

Source: https://waline.js.org/en/reference/server/plugin

Demonstrates creating a Waline server plugin using the hooks system. This allows executing custom logic after specific events, such as a comment being saved. The `postSave` hook is shown as an example.

```javascript
module.exports = {
  hooks: {
    async postSave() {
      // do what ever you want after comment saved
    },
  },
};
```

### Configure Python Path for Node-gyp

Source: https://waline.js.org/guide/deploy/aliyun-fc

Specifies the path to the Python executable for node-gyp. This is necessary if multiple Python versions are installed or if node-gyp cannot automatically find the correct Python installation. Node-gyp supports Python versions 3.7 through 3.10.

```shell
npm config set python "/path/to/executable/python"
```
