## 开发
### 编写脚本 ```hello.lua```
```lua
function descriptor()
    return {
        title = "Hello World";
        version = "1.0";
        author = "WangJunjian";
        url = 'www.wangjunjian.com';
        shortdesc = "Hello World";
        description = "Hello World!";
        capabilities = {"menu"}
    }
end

-- activate() : called when the extension is activated from within VLC
function activate()
    create_dialog()
end

-- deactivate() : called when the extension is deactivated from within VLC
function deactivate()
    close()
    vlc.deactivate()
end

-- create_dialog() : creates the dialog containing the initial widgets
function create_dialog()
    dlg = vlc.dialog(descriptor().title)
    dlg:add_label("<b>Hello World: VLC Lua scripts and extensions</b>")
end
```
