# Official Plugin Integration
|
|
|
|
Halo's official plugins can extend the frontend UI. Themes should adapt to these plugins rather than re-implementing the same functionality.
|
|
|
|
## Checking Plugin Availability
|
|
|
|
Use `pluginFinder.available(pluginName)` to conditionally render plugin-dependent UI. This prevents broken UI when the plugin is not installed.
|
|
|
|
```html
|
|
<button
|
|
th:if="${pluginFinder.available('PluginSearchWidget')}"
|
|
onclick="javascript:SearchWidget.open()"
|
|
>
|
|
Search
|
|
</button>
|
|
```
|
|
|
|
Always guard plugin-dependent elements with `th:if="${pluginFinder.available('...')}"`.
|
|
|
|
## Search Widget (PluginSearchWidget)
|
|
|
|
The official search plugin provides a ready-made search UI. Themes do not need to build their own search — just add a trigger button:
|
|
|
|
```html
|
|
<button
|
|
th:if="${pluginFinder.available('PluginSearchWidget')}"
|
|
onclick="javascript:SearchWidget.open()"
|
|
>
|
|
Search
|
|
</button>
|
|
```
|
|
|
|
## Dark Mode Adaptation
|
|
|
|
Official plugins that provide UI components (search widget, comment component, etc.) support a shared color scheme system. Themes that implement dark mode should apply the appropriate class or `data-color-scheme` attribute to `<html>` or `<body>` so plugin UI matches the theme's color scheme automatically.
|
|
|
|
### Method 1: CSS class on `<html>` or `<body>`
|
|
|
|
| Class | Effect |
|
|
| ------------------------------- | ------------------------------------ |
|
|
| `color-scheme-auto` | Follows system dark/light preference |
|
|
| `color-scheme-dark` or `dark` | Force dark mode |
|
|
| `color-scheme-light` or `light` | Force light mode |
|
|
|
|
```html
|
|
<html class="color-scheme-dark">
|
|
<!-- or -->
|
|
|
|
<html class="dark"></html>
|
|
</html>
|
|
```
|
|
|
|
### Method 2: `data-color-scheme` attribute on `<html>` or `<body>`
|
|
|
|
| Value | Effect |
|
|
| ------- | ------------------------- |
|
|
| `auto` | Follows system preference |
|
|
| `dark` | Force dark mode |
|
|
| `light` | Force light mode |
|
|
|
|
```html
|
|
<html data-color-scheme="auto"></html>
|
|
```
|
|
|
|
> Both methods achieve the same result. Dark mode switching is typically handled by frontend JavaScript (toggling the class/attribute at runtime). This applies to all official plugins that render UI (search widget, comment component, etc.).
