Installation

Install via composer with

$ composer install kagagnon/bem-blade

After successfully installing BEM Blade, add the service provider in your app configs.

KAGagnon\BEMBlade\BEMServiceProvider::class,

The service provider will boot and register new directives in the Blade engine.

Optional configurations

You can publish the config file with the following command:

$ php artisan vendor:publish --provider="KAGagnon\BEMBlade\BEMServiceProvider" --tag="config"

You can then change your element and modifier separators to your liking.

<?php
return [

    /**
     * Separator between block and element
     *
     * Default: '__'
     */
    'element_separator' => '__',

    /**
     * Separator between modifer and block/element
     *
     * Default: '--'
     */
    'modifier_separator' => '--',

    /**
     * Should @bem create a tag element
     *
     * Default: false
     */
    'create_tag' => false,

    /**
     * If create_tag is true, what's the default tag name
     *
     * Default: 'div'
     */
    'default_tag' => 'div',

    /**
     * Prefix of BEM classes.
     *
     * Default: ''
     */
    'block_prefix' => '',
];

How to use

Blocks

You can create a new block with the directive @bem( $block_name ). Once the block if finished, you can use @endbem to close the block. BEM block can be nest for sub-module. So this:

@bem( 'block' )
    @bem( 'other-block )
    @endbem
@endbem

is a valid syntax.

Classes

To generate a class, you can use @bemclass( [ string|array $element, [ string|array $modifiers ] ] ).

  • Passing no arguments generate the block name.
  • Passing a string as first argument generate the block name with an element.
  • Passing an array as first argument generate the block name with the modifiers.
  • Passing a string and an array generate a block name with an element and its modifiers.
  • Passing 2 strings generate a block name with an element and explode the string on spaces to generate the modifiers.

Check the examples below:

@bem( 'cup' ) // Init Block "cup"
    @bemclass() // Generate : cup
    @bemclass( [ 'glass' ] ) // Generate : cup cup--glass

    @bem( 'spoon' ) // Init Block "spoon"
        @bemclass // Generate : spoon
        @bemclass( [ 'metallic', 'cold' ] ) // Generate : spoon spoon--metallic spoon--cold
        @bemclass( 'sugar' ) // Generate : spoon__sugar
        @bemclass( 'sugar', 'half-tea-spoon' ) // Generate : spoon__sugar spoon__sugar--half-tea-spoon
    @endbem

    @bemclass( 'tea' ) // Generate : cup__tea
    @bemclass( 'coffee' ) // Generate : cup_coffee
    @bemclass( 'coffee' , 'with-sugar' ) // Generate : cup__coffee cup__coffee--with-sugar
    @bemclass( 'coffee' , [ 'with-sugar', 'with-milk'] ) // Generate : cup__coffee cup__coffee--with-sugar cup__coffee--with-milk
    @bemclass( 'coffee' , 'with-sugar with-milk no-foam' ) // Generate : cup__coffee cup__coffee--with-sugar cup__coffee--with-milk cup__coffee--no-foam
@endbem

HTML example

@bem( 'article' )
   <div class="@bemclass">
       <h1 class="@bemclass( 'title' )">Article Name</h1>

       <p class="@bemclass( 'content' )">Article text...</p>

       @bem( 'meta' )
           <div class="@bemclass">
               <a href="..." class="@bemclass( 'link', 'inactive' )">0 comments</a>
               <a href="..." class="@bemclass( 'link', 'clear danger' )">Delete</a>
               <a href="..." class="@bemclass( 'link' )">Edit</a>
           </div>
       @endbem
   </div>
@endbem

Result to :

<div class="article">
   <h1 class="article__title">Article Name</h1>

   <p class="article__content">Article text...</p>

   <div class="meta">
       <a href="..." class="meta__link--inactive">0 comments</a>
       <a href="..." class="meta__link--clear meta__link--danger">Delete</a>
       <a href="..." class="meta__link">Edit</a>
   </div>
</div>

Create node with @bem

You can pass argument to @bem to automatically generate an HTML tag. To do so, you can pass the tag name as second argument and, optionally, an array of attributes.

You can also skip the tag name and pass an array as second argument. That will create an HTML element base on the default_tag configuration.

Additionally, if you set create_tag to true, @bem() will always create a tag base on the default_tag configuration if only 1 argument is passed.

To pass modifiers to the tag, simply pass _modifiers in the array: an array for multi-modifiers ou a string for single modifier.

Example

{{-- We assume `create_tag` is set to true --}}
@bem( 'block' ) // <div class="block">
@endbem         // </div>

@bem( 'block', 'article' ) // <article class="block">
@endbem                    // </article>

@bem( 'block', 'quote', [ 'data-inspiration', 'class' => 'js-action' ] ) // <quote class="js-action block" data-inspiration >
@endbem                                                                  //</quote>

@bem( 'block', [ 'id' => "anchor" ] ) // <div class="block" id="anchor">
@endbem                               // </div>

@bem( 'block', [ 'id' => "anchor", '_modifiers' => 'modifier' ] ) // <div class="block block--modifier" id="anchor">
@endbem                               // </div>

@bem( 'block', [ '_modifiers' => [ 'modifier1', 'modifier2' ] ] ) // <div class="block block--modifier1 block--modifier2">
@endbem                               // </div>
