Introduction To Sly Template Engine
===================================

[](#introduction-to-sly-template-engine)

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
------------------------------

[](#installing-on-separate-project)

The recommended way to install sly is via Composer:

```
composer require "billitech/sly:~0.1"

```

Basic Usage
-----------

[](#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
---------------

[](#disable-caching)

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

```
$sly = new Sly($loader);
```

Other configurations
--------------------

[](#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
------

[](#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)

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

```

        @( title )

        @for( user in users )
            >@( user )
        @end

```

### Sly Expression

[](#sly-expression)

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

#### Printing expression

[](#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
