Theme

You can mange themes and layouts of Lavalite.

Usage

Theme has many features to help you get started with Laravel

Configuration

After the config is published, you will see the config file in "config/theme", but all the configuration can be replaced by a config file inside a theme.

Theme config location: /public/themes/[theme]/config.php

The config is convenient for setting up basic CSS/JS, partial composer, breadcrumb template and also metas.

'events' => array(

    // Before event inherit from package config and the theme that call before,
    // you can use this event to set meta, breadcrumb template or anything
    // you want inheriting.
    'before' => function($theme)
    {
        // You can remove this line anytime.
        $theme->setTitle('Copyright ©  2016 - lavalite.org');

        // Breadcrumb template.
        // $theme->breadcrumb()->setTemplate('
        //     <ul class="breadcrumb">
        //     @foreach ($crumbs as $i => $crumb)
        //         @if ($i != (count($crumbs) - 1))
        //         <li><a href="{{ $crumb["url"] }}">{{ $crumb["label"] }}</a><span class="divider">/</span></li>
        //         @else
        //         <li class="active">{{ $crumb["label"] }}</li>
        //         @endif
        //     @endforeach
        //     </ul>
        // ');
    },

    // Listen on event before render a theme,
    // this event should call to assign some assets,
    // breadcrumb template.
    'beforeRenderTheme' => function($theme)
    {
        // You may use this event to set up your assets.
        // $theme->asset()->usePath()->add('core', 'core.js');
        // $theme->asset()->add('jquery', 'vendor/jquery/jquery.min.js');
        // $theme->asset()->add('jquery-ui', 'vendor/jqueryui/jquery-ui.min.js', array('jquery'));


        // $theme->partialComposer('header', function($view)
        // {
        //     $view->with('auth', Auth::user());
        // });
    },

    // Listen on event before render a layout,
    // this should call to assign style, script for a layout.
    'beforeRenderLayout' => array(

        'default' => function($theme)
        {
            // $theme->asset()->usePath()->add('ipad', 'css/layouts/ipad.css');
        }

    )

)

Basic usage

namespace App\Http\Controllers;

use Theme;

class HomeController extends Controller {

    public function getIndex()
    {
        $theme = Theme::uses('default')->layout('mobile');

        $view = array(
            'name' => 'Litepie'
        );

        // home.index will look up the path 'resources/views/home/index.php'
        return $theme->of('home.index', $view)->render();

        // Specific status code with render.
        return $theme->of('home.index', $view)->render(200);

        // home.index will look up the path 'resources/views/mobile/home/index.php'
        return $theme->ofWithLayout('home.index', $view)->render();

        // home.index will look up the path 'public/themes/default/views/home/index.php'
        return $theme->scope('home.index', $view)->render();

        // home.index will look up the path 'public/themes/default/views/mobile/home/index.php'
        return $theme->scopeWithLayout('home.index', $view)->render();

        // Looking for a custom path.
        return $theme->load('app.somewhere.viewfile', $view)->render();

        // Working with cookie.
        $cookie = Cookie::make('name', 'Tee');
        return $theme->of('home.index', $view)->withCookie($cookie)->render();
    }

}

Get only content "$theme->of('home.index')->content();".

Finding from both theme's view and application's view.

$theme = Theme::uses('default')->layout('default');

return $theme->watch('home.index')->render();

To check whether a theme exists.

// Returns boolean.
Theme::exists('themename');

To find the location of a view.

$which = $theme->scope('home.index')->location();

echo $which; // themer::views.home.index

$which = $theme->scope('home.index')->location(true);

echo $which; // ./public/themes/name/views/home/index.blade.php

Compiler

Theme supports PHP, Blade and Twig. To use Blade or Twig template you just create a file with extension


[file].blade.php or [file].twig.php

Render from string

// Blade template.
return $theme->string('<h1>{{ $name }}</h1>', array('name' => 'Litepie'), 'blade')->render();

// Twig Template
return $theme->string('<h1>{{ name }}</h1>', array('name' => 'Litepie'), 'twig')->render();

Compile string

// Blade compile.
$template = '<h1>Name: {{ $name }}</h1><p>{{ Theme::widget("WidgetIntro", array("userId" => 9999, "title" => "Demo Widget"))->render() }}</p>';

echo Theme::blader($template, array('name' => 'Litepie'));
// Twig compile.
$template = '<h1>Name: {{ name }}</h1><p>{{ Theme.widget("WidgetIntro", {"userId" : 9999, "title" : "Demo Widget"}).render() }}</p>';

echo Theme::twigy($template, array('name' => 'Litepie'));

Symlink from another view

This is a nice feature when you have multiple files that have the same name, but need to be located as a separate one.

// Theme A : /public/themes/a/views/welcome.blade.php

// Theme B : /public/themes/b/views/welcome.blade.php

// File welcome.blade.php at Theme B is the same as Theme A, so you can do link below:

// ................

// Location: public/themes/b/views/welcome.blade.php
Theme::symlink('a');

// That's it!

Basic usage of assets

Add assets in your route or controller.

// path: public/css/style.css
$theme->asset()->add('core-style', 'css/style.css');

// path: public/js/script.css
$theme->asset()->container('footer')->add('core-script', 'js/script.js');

// path: public/themes/[current theme]/assets/css/custom.css
// This case has dependency with "core-style".
$theme->asset()->usePath()->add('custom', 'css/custom.css', array('core-style'));

// path: public/themes/[current theme]/assets/js/custom.js
// This case has dependency with "core-script".
$theme->asset()->container('footer')->usePath()->add('custom', 'js/custom.js', array('core-script'));

You can force use theme to look up existing theme by passing parameter to method: $theme->asset()->usePath('default')

Writing in-line style or script.

// Dependency with.
$dependencies = array();

// Writing an in-line script.
$theme->asset()->writeScript('inline-script', '
    $(function() {
        console.log("Running");
    })
', $dependencies);

// Writing an in-line style.
$theme->asset()->writeStyle('inline-style', '
    h1 { font-size: 0.9em; }
', $dependencies);

// Writing an in-line script, style without tag wrapper.
$theme->asset()->writeContent('custom-inline-script', '
    <script>
        $(function() {
            console.log("Running");
        });
    </script>
', $dependencies);

Render styles and scripts in your layout.

// Without container
echo Theme::asset()->styles();

// With "footer" container
echo Theme::asset()->container('footer')->scripts();

Direct path to theme asset.

echo Theme::asset()->url('img/image.png');

Preparing group of assets.

Some assets you don't want to add on a page right now, but you still need them sometimes, so "cook" and "serve" is your magic.

Cook your assets

Theme::asset()->cook('backbone', function($asset)
{
    $asset->add('backbone', '//cdnjs.cloudflare.com/ajax/libs/backbone.js/1.0.0/backbone-min.js');
    $asset->add('underscorejs', '//cdnjs.cloudflare.com/ajax/libs/underscore.js/1.4.4/underscore-min.js');
});

You can prepare on a global in package config.

// Location: config/theme/config.php
....
    'events' => array(

        ....

        // This event will fire as a global you can add any assets you want here.
        'asset' => function($asset)
        {
            // Preparing asset you need to serve after.
            $asset->cook('backbone', function($asset)
            {
                $asset->add('backbone', '//cdnjs.cloudflare.com/ajax/libs/backbone.js/1.0.0/backbone-min.js');
                $asset->add('underscorejs', '//cdnjs.cloudflare.com/ajax/libs/underscore.js/1.4.4/underscore-min.js');
            });
        }

    )
....

Serve theme when you need.

// At the controller.
Theme::asset()->serve('backbone');

Then you can get output.

...
<head>
    <?php echo Theme::asset()->scripts(); ?>
    <?php echo Theme::asset()->styles(); ?>
    <?php echo Theme::asset()->container('YOUR_CONTAINER')->scripts(); ?>
    <?php echo Theme::asset()->container('YOUR_CONTAINER')->styles(); ?>
</head>
...

Partials

Render a partial in your layouts or views.

// This will look up to "public/themes/[theme]/partials/header.php"
echo Theme::partial('header', array('title' => 'Header'));

// Partial with current layout specific.
// This will look up up to "public/themes/[theme]/partials/[CURRENT_LAYOUT]/header.php"
echo Theme::partialWithLayout('header', array('title' => 'Header'));

Finding from both theme's partial and application's partials.

echo Theme::watchPartial('header', array('title' => 'Header'));

Partial composer.

$theme->partialComposer('header', function($view)
{
    $view->with('key', 'value');
});

// Working with partialWithLayout.
$theme->partialComposer('header', function($view)
{
    $view->with('key', 'value');
}, 'layout-name');

Working with regions

Theme has magic methods to set, prepend and append anything.

$theme->setTitle('Your title');

$theme->appendTitle('Your appended title');

$theme->prependTitle('Hello: ....');

$theme->setAnything('anything');

$theme->setFoo('foo');

// or

$theme->set('foo', 'foo');

Render in your layout or view.

Theme::getAnything();

Theme::getFoo();

// or use place.

Theme::place('anything');

Theme::place('foo', 'default-value-if-it-does-not-exist');

// or

Theme::get('foo');

Check if the place exists or not.

<?php if (Theme::has('title')) : ?>
    <?php echo Theme::place('title'); ?>
<?php endif; ?>

// or

<?php if (Theme::hasTitle()) : ?>
    <?php echo Theme::getTitle(); ?>
<?php endif; ?>

Get argument assigned to content in layout or region.

Theme::getContentArguments();

// or

Theme::getContentArgument('name');

// To check if it exists

Theme::hasContentArgument('name');

Theme::place('content') is a reserve region to render sub-view.

Preparing data to view

Sometimes you don't need to execute heavy processing, so you can prepare and use when you need it.

$theme->bind('something', function()
{
    return 'This is bound parameter.';
});

Using bound data on view.

echo Theme::bind('something');

Breadcrumb

In order to use breadcrumbs, follow the instruction below:

$theme->breadcrumb()->add('label', 'http://...')->add('label2', 'http:...');

// or

$theme->breadcrumb()->add(array(
    array(
        'label' => 'label1',
        'url'   => 'http://...'
    ),
    array(
        'label' => 'label2',
        'url'   => 'http://...'
    )
));

To render breadcrumbs.

echo $theme->breadcrumb()->render();

// or

echo Theme::breadcrumb()->render();

You can set up breadcrumbs template anywhere you want by using a blade template.

$theme->breadcrumb()->setTemplate('
    <ul class="breadcrumb">
    @foreach ($crumbs as $i => $crumb)
        @if ($i != (count($crumbs) - 1))
        <li><a href="{{ $crumb["url"] }}">{{ $crumb["label"] }}</a><span class="divider">/</span></li>
        @else
        <li class="active">{{ $crumb["label"] }}</li>
        @endif
    @endforeach
    </ul>
');

<h1>User Id: {{ $label }}</h1>

Calling your widget in layout or view

echo Theme::widget('demo', array('label' => 'Demo Widget'))->render();

Using theme global

use Litepie\Theme\Contracts\Theme;
use App\Http\Controllers\Controller;

class BaseController extends Controller {

    /**
     * Theme instance.
     *
     * @var \Litepie\Theme\Theme
     */
    protected $theme;

    /**
     * Construct
     *
     * @return void
     */
    public function __construct(Theme $theme)
    {
        // Using theme as a global.
        $this->theme = $theme->uses('default')->layout('ipad');
    }

}

To override theme or layout.

public function getIndex()
{
    $this->theme->uses('newone');
        // or just override layout
    $this->theme->layout('desktop');

    $this->theme->of('somewhere.index')->render();
}
