Nova Template Engine: انقلابی در دنیای موتورهای قالب - ساختارشکنی سینتکس‌های سنتی

// In Twig you should write like this:
{{ variable }}

{{ variable|filter }}

// In Blade you should write like this:
{{ $variable }}
@foreach($items as $item)
    {{ $item->name }}
@endforeach
{{ $variable }}

// In Smarty you should write like this:
{$variable}
{foreach $items as $item}
    {$item.name}
{/foreach}
{$variable|filter}

// In Nova you just write:
@var(variable)
@for(item in items)
    @var(item.name)
@endfor
@var(variable|filter)

// Recognize simple and multidimensional arrays
@var(users.0.name)           // $users[0]['name']
@var(users['admin'].email)   // $users['admin']['email']
@var(posts.2.comments.5.text) // $posts[2]['comments'][5]['text']

// تشخیص توابع و متدهای استاتیک
@var(User::getActiveCount())  // User::getActiveCount()
@var(Helper::formatDate(created_at)) // Helper::formatDate($created_at)

// تشخیص ثابت‌ها
@var(App::VERSION)           // App::VERSION
@var(PROJECT_STATUS_ACTIVE)  // PROJECT_STATUS_ACTIVE

// هر دو سینتکس کار می‌کنند!
@var(user.name)     // $user['name'] or $user->name
@var($user.name)    // $user['name'] or $user->name
@var(post.title)    // $post['title'] or $post->title
@var($post.title)   // $post['title'] or $post->title
