Syntax [RU]

Fenom implement Smarty syntax with some improvements

Variable

Use variables

{$foo}
{$bar}
{$foo[4]}
{$foo.4}
{$foo.bar}
{$foo.'bar'}
{$foo."bar"}
{$foo['bar']}
{$foo["bar"]}
{$foo.$bar}
{$foo[$bar]}
{$foo->bar}
{$foo->bar.buz}

System variable

Unnamed system variable starts with $. and allow access to global variables and system info (fix doc):

$.get is $_GET.
$.post is $_POST.
$.cookie is $_COOKIE.
$.session is $_SESSION.
$.globals is $GLOBALS.
$.request is $_REQUEST.
$.files is $_FILES.
$.server is $_SERVER.
$.env is $_ENV.
$.tpl.name returns current template name.
$.tpl.schema returns current schema of the template.
$.version returns version of the Fenom.
$.const paste constant.

{if $.get.debug? && $.const.DEBUG}
   ...
{/if}

Multidimensional value support

{$foo.bar.baz}
{$foo.$bar.$baz}
{$foo[4].baz}
{$foo[4].$baz}
{$foo.bar.baz[4]}
{$foo[ $bar.baz ]}

Math operations

{$x+$y}
{$foo[$x+3]}
{$foo[$x+3]*$x+3*$y % 3}

See all operators

Object support

{$object->item}
{$object->item|upper} {* apply modifier *}
{$object->item->method($y, 'named')}
{$object->item->method($y->name, 'named')|upper} {* apply modifier to method result*}

You may disable call methods in template, see in security options option deny_method

Static method support

{Lib\Math::multiple x=3 y=4} static method as tag
{Lib\Math::multiple(3,4)}  inline static method
{12 + Lib\Math::multiple(3,4)}
{12 + 3|Lib\Math::multiple:4}  static method as modifier

You may disable call static methods in template, see in security options option deny_static

Set variable

{var $foo = "bar"}
{var $foo = "bar"|upper} {* apply modifier *}
{var $foo = 5}
{var $foo = $x + $y}
{var $foo = $x.y[z] + $y}
{var $foo = strlen($a)} {* work with functions *}
{var $foo = myfunct( ($x+$y)*3 )}
{var $foo.bar.baz = 1} {* multidimensional value support *}
{var $foo = $object->item->method($y, 'named')} {* work with object fine *}

Using block tag

{var $foo}
    content {$text|truncate:30}
{/var}
{var $foo|truncate:50} {* apply modifier to content *}
    content {$text}
{/var}

Set array

{var $foo = [1, 2, 3]} numeric array
{var $foo = ['y' => 'yellow', 'b' => 'blue']} associative array
{var $foo = [1, [9, 8], 3]} can be nested
{var $foo = [1, $two, $three * 3 + 9]}
{var $foo = [$a, $d.c, $a + $f]}
{var $foo = ['y' => 'yellow', $color|upper => $colors[ $color ]}
{var $foo = [1, [$parent, $a->method()], 3]}

Scalar values

Strings

When the string in double quotation marks, all the expressions in the string will be run. The result of expressions will be inserted into the string instead it.

{var $foo="Username"}
{var $user.name="Username"}
{"Hi, $foo"}          outputs "Hi, Username"
{"Hi, {$foo}"}        outputs "Hi, Username"
{"Hi, {$user.name}"}  outputs "Hi, Username"
{"Hi, {$user.name|up}"} outputs "Hi, USERNAME"
{"Hi, {$user->getName(true)}"} outputs Hi, Username
{var $message = "Hi, {$user.name}"}

but if use single quote any template expressions will be on display as it is

{'Hi, $foo'}            outputs 'Hi, $foo'
{'Hi, {$foo}'}          outputs 'Hi, {$foo}'
{'Hi, {$user.name}'}    outputs 'Hi, {$user.name}'
{'Hi, {$user.name|up}'} outputs "Hi, {$user.name|up}"

Numbers

{2|pow:10}
{var $magick = 5381|calc}
{0.2|round}
{1e-6|round}

Modifiers

Modifiers allows change some value before output or using.
To apply a modifier, specify the value followed by a | (pipe) and the modifier name.
A modifier may accept additional parameters that affect its behavior. These parameters follow the modifier name and are separated by a : (colon).

{var $foo="User"}
{$foo|upper}            outputs "USER"
{$foo|lower}            outputs "user"
{"{$foo|lower}"}        outputs "user"
{"User"|lower}}         outputs "user"
{$looong_text|truncate:80:"..."}  truncate the text to 80 symbols and append <continue> symbols, like "..."
{$looong_text|lower|truncate:$settings.count:$settings.etc}
{var $foo="Ivan"|upper}    sets $foo value "USER"

List of modifiers

Ignoring template code

В шаблонизаторе Fenom используются фигурные скобки для отделения HTML от кода Fenom. Если требуется вывести текст, содержащий фигурные скобки, помните о следующих возможностях:

Использование блочного тега {ignore}{/ignore}. Текст внутри этого тега текст не компилируется шаблонизатором и выводится как есть.
Если после открывающей фигурной скобки есть пробельный символ (пробел или \t) или перенос строки (\r или \n), то она не воспринимается как разделитель кода Fenom и код после неё выводится как есть.

Пример:

{ignore}
<style>
	h1 {font-size: 24px; color: #F00;}
</style>
{/ignore}
<script>
	(function (text) {
		var e = document.createElement('P');
		e.innerHTML = text;
		document.body.appendChild(e);
	})('test');
</script>
{if:ignore $js_enabled}

{/if}

Outputs

<style>
	h1 {font-size: 24px; color: #F00;}
</style>
<script>
	(function (text) {
		var e = document.createElement('P');
		e.innerHTML = text;
		document.body.appendChild(e);
	})('test');
</script>

Whitespaces

Шаблонизатор допускает любое количество пробелов или переносов строк в своём коде

{include 'control.tpl'
    $options = $list
    $name    = $cp.name
    $type    = 'select'
    isolate  = true
    disable_static = true
}

{foreach [
    "one"   => 1,
    "two"   => 2,
    "three" => 3
] as $key   => $val}

    {$key}: {$val}

{/foreach}
