## 🔌 Plugin System  

Shahnevis Core supports a **plugin system** that allows developers to extend functionality dynamically.

### 📥 Creating a Plugin  

Here's an example of a **Preview Plugin** that updates an iframe when the user writes HTML code:  

```js
export default {
  init() {
    console.log("Preview Plugin Loaded!");
  },

  onLanguageChange(language) {
    if (language === "html") {
      console.log("HTML selected!");
    }
  },

  onInput() {
    const languageSelector = document.getElementById("language-selector");
    const previewFrame = document.getElementById("preview-frame");
    const editor = document.getElementById("editor");

    if (!languageSelector || !previewFrame || !editor) {
      console.warn("Preview Plugin: Missing required DOM elements.");
      return;
    }

    const language = languageSelector.value;
    if (language === "html") {
      previewFrame.srcdoc = editor.value;
    }
  }
};
```

### 🛠️ Registering the Plugin  

To register this plugin, use:  

```js
const pluginURLs = [
    'path to plugin'
]

const loadPlugins = async () => {
    await loadExternalPlugins(pluginURLs);
    console.log("Plugins loaded.");
};
loadPlugins();
```

## 🌍 Supported Languages  

Shahnevis Core comes with built-in support for multiple programming languages via the `languages` module. You can extend this list with additional parsers.
