README

The sly template engine is a very powerful template engine for PHP, it is very fast both at compile and run time.

The template engine syntax by default is a bit similar to ASP.NET razor.

The sly component is independent from the Billi tech framework which means it can be used on any project.

Installing on separate project

The recommended way to install sly is via Composer:

composer require "billitech/sly:~0.1"

Basic Usage

//place at the top of your script
use Billitech\Sly\Sly;
use Billitech\Sly\FileLoader;
$loader = new FileLoader(['/path/to/your/templates']);
$sly = new Sly($loader, '/path/to/store/compiled_files');

echo $sly->render('index.sly', ['title' => 'Sly Template Ingine']);

Then Create a file with the name index.sly in the path you specify when creating the FileLoader instance and put the following code in it :

@( title )

When creating the FileLoader instance you can specify a array of paths where your templates are.

Disable caching

To disable caching do not specify compile path while creating sly instance, for example :

$sly = new Sly($loader);

Other configurations

$sly->setCharset('utf8'); // Set the character encoding of your templates.
$sly->enableAutoEscape(); // Enable auto escape. 
$sly->disableAutoEscape(); // Disable auto escape.
$sly->enableStrictVariables(); // Enable strict variable.
$sly->disableStrictVariables(); // Disable strict variable.

Auto escape is on by default.

Syntax

The sly template engine uses th @ symbol to indicate start of a sly statement. @( is used to start a print statement and ) is used to close a print statement i.e @( abs(-1) ). while @ is used to start a control statement and ) is used to close a control statement i.e @if( true ).

Variable

Variable passes to the the template can be access within the the template by usin the name of the variable in an expression. for example : php file

$sly->render('users.sly', ['users' => ['foo', 'bar', 'barz'], 'title' => 'My Users']);

users.sly

<html>
    <head>
        <title>@( title )</title>
    </head>
    <body>
        <ul class="users">
        @for( user in users )
            <li>>@( user )</li>
        @end
        </ul>
    </body>
</html>

Sly Expression

The sly template engine accept most valid php experessions with some few additional expressions.

Printing expression

By default the sly template use @( ) syntax to print an expression. for example @(1 + 1) will be printed as 2. everything within the curly bracket must be a valid php expression and by default the printed expression will be automatically escaped using php htmlspecialchars function if the expression returns a string or sting convertable value, or the value will be converted to JSON using php json_encode function.

Sly template unlike other pupuler template engines, u can use any php function within an expression
