BladeOne

BladeOne is a standalone version of Blade Template Engine that uses a single php file and can be ported and used in different projects.

Introduction (From Laravel webpage)

Blade is the simple, yet powerful templating engine provided with Laravel. Unlike other popular PHP templating engines, Blade does not restrict you from using plain PHP code in your views. All Blade views are compiled into plain PHP code and cached until they are modified, meaning Blade adds essentially zero overhead to your application. Blade view files use the .blade.php file extension and are typically stored in the resources/views directory.

About this version

By standard, Blade is part of Laravel (Illuminate components) and for to use it, you requires to install Laravel and Illuminate-view components. Blade as a template engine is pretty nice and clear. Also it generates a (some that) clean code. And its starting to be considered a de-facto template system for php (Smarty has been riding off the sunset since years ago). So, if we are able to use it without Laravel then its a big plus for many projects. In fact, in theory its is even possible to use with Laravel. Exists different version of Blade Template that runs without Laravel but most requires 50 or more files and those templates add a new level of complexity:

• More files to manages.
• Changes to the current project (if you want to integrate the template into an existent one)
• Incompatibilities amongst other projects.
• Slowness (if your server is not using op-cache)
• Most of the code in the original Blade is used for future use, including the chance to use a different template engine.
• Some Laravel legacy code.

This project uses a single file called BladeOne.php and a single class (called BladeOne). If you want to use it then include it, creates the folders and that's it!. Nothing more (not even namespaces)*[]:

Usage

example.php:

<?php
include "BladeOne.php";
Use eftec\bladeone;

$views = __DIR__ . '/views';
$cache = __DIR__ . '/cache';
define("BLADEONE_MODE",1); // (optional) 1=forced (test),2=run fast (production), 0=automatic, default value.
$blade=new bladeone\BladeOne($views,$cache);
echo $blade->run("hello",array("variable1"=>"value1"));

Or using composer's autoload.php

<?php
require "vendor/autoload.php";

Use eftec\bladeone;

$views = __DIR__ . '/views';
$cache = __DIR__ . '/cache';
define("BLADEONE_MODE",1); // (optional) 1=forced (test),2=run fast (production), 0=automatic, default value.
$blade=new bladeone\BladeOne($views,$cache);
echo $blade->run("hello",array("variable1"=>"value1"));

(modify composer.json as follow) and run "composer update"

"autoload": {
  "psr-4": {
    "eftec\\": "vendor/eftec/"
  }
}

Where $views is the folder where the views (templates not compiled) will be stored. $cache is the folder where the compiled files will be stored.

In this example, the BladeOne opens the template hello. So in the views folders it should exists a file called hello.blade.php

views/hello.blade.php:

<h1>Title</h1>
{{$variable1}}

Business Logic/Controller methods

constructor

$blade=new bladeone\BladeOne($views,$cache);

• BladeOne(templatefolder,compiledfolder) Creates the instance of BladeOne.
• templatefolders indicates the folder (without ending backslash) of where the template files (*.blade.php) are located.
• compiledfolder indicates the folder where the result of files will be saves. This folder should has write permission. Also, this folder could be located outside of the Web Root.

run

echo $blade->run("hello",array("variable1"=>"value1"));

• run([template,[array]) Runs the template and generates a compiled version (if its required), then it shows the result.
• template is the template to open. The dots are used for to separate folders. If the template is called "folder.example" then the engine tries to open the file "folder\example.blade.php"
• array (optional). Indicates the values to use for the template. For example ['v1'=>10'], indicates the variable $v1 is equals to 10

BLADEONE_MODE (global constant) (optional)

define("BLADEONE_MODE",1); // (optional) 1=forced (test),2=run fast (production), 0=automatic, default value.

• BLADEONE_MODE Is a global constant that defines the behaviour of the engine.
• 1=forced. Indicates that the engine always will compile the template.
• 2=fast. Indicates that the engine always will use the compiled version

Template tags

Template Inheritance

In the master page (layout)

Using the master page (using the layout)

Note :(*) This feature is in the original documentation but its not implemented neither its required. May be its an obsolete feature.

variables

logic

loop

Sub Views

Comments

Stacks

@set (new for 1.5)

@set($variable=[value]) @set($variable) is equals to @set($variable=$variable+1)

• $variable define the variable to add. If not value is defined the it adds +1 to a variable.
• value (option) define the value to use.

##Differences between Blade and BladeOne

• Laravel's extension removed.
• Dependencies to other class removed (around 30 classes).
• The engine is self contained.
• Setter and Getters removed. Instead, we are using the PHP style (public members).
• BladeOne doesn't support static calls.

Differences between Blade+Laravel and BladeOne+BladeOneHTML

Instead of use the Laravel functions, for example Form::select

{{Form::select('countryID', $arrayCountries,$countrySelected)}}

We have native tags as @select,@item,@items and @endselect

@select('countryID')
    @item('0','--Select a country--',$countrySelected)
    @items($arrayCountries,'id','name',$countrySelected)
@endselect()

This new syntaxis add an (optionally) a non-selected row. Also, BladeOneHTML adds multiple select, fixed values (without array), grouped select and many more.

##Todo

• - Some features are missing , with bugs or not tested but the basic ones are working. DONE
• - @each could be optimized. DONE
• - There are several tags of undocumented features of the original Blade code. DONE
• - Extending BladeOne opens a world of opportunities.
• ~~ May be a bladeone-bootstrap3 class in the future.~~ Done
• - Speed up the loading of compiled templates. DONE

##Version

• 2016-06-08 0.2. Beta First publish launch.
