=====
|

|
||
## Configure
|
||
|
||
### Template cache
|
||
|
||
```php
|
||
$fenom->setCompileDir($dir);
|
||
```
|
||
|
||
This method set the name of the directory where template caches are stored. By default this is `/tmp`. This directory must be writeable.
|
||
|
||
### Template settings
|
||
|
||
```php
|
||
// set options using factory
|
||
$fenom = Fenom::factory($tpl_dir, $compile_dir, $options);
|
||
// or inline using method setOptions
|
||
$fenom->setOptions($options);
|
||
```
|
||
|
||
Options may by associative array like `'option_name' => true` or bitwise mask.
|
||
|
||
| Option name | Constant | Description | Affect |
|
||
| ---------------------- | ------------------------- | ------------ | ------- |
|
||
| *disable_methods* | `Fenom::DENY_METHODS` | disable calling methods of objects in templates. | |
|
||
| *disable_native_funcs* | `Fenom::DENY_NATIVE_FUNCS`| disable calling native function in templates, except allowed. | |
|
||
| *auto_reload* | `Fenom::AUTO_RELOAD` | reload template if source will be changed | decreases performance |
|
||
| *force_compile* | `Fenom::FORCE_COMPILE` | recompile template every time when the template renders | very decreases performance |
|
||
| *disable_cache* | `Fenom::DISABLE_CACHE` | disable compile cache | greatly decreases performance |
|
||
| *force_include* | `Fenom::FORCE_INCLUDE` | paste template body instead of include-tag | increases performance, increases cache size |
|
||
| *auto_escape* | `Fenom::AUTO_ESCAPE` | html-escape each variables outputs | decreases performance |
|
||
| *force_verify* | `Fenom::FORCE_VERIFY` | check existence every used variable | decreases performance |
|
||
<!-- | *auto_trim* | `Fenom::AUTO_TRIM` | remove space-characters before and after tags | | -->
|
||
| *disable_statics* | `Fenom::DENY_STATICS` | disable calling static methods in templates. | |
|
||
| *strip* | `Fenom::AUTO_STRIP` | strip all whitespaces in templates. | decrease cache size |
|
||
|
||
```php
|
||
$fenom->setOptions(array(
|
||
"force_compile" => true,
|
||
"force_include" => true
|
||
));
|
||
// same
|
||
$fenom->setOptions(Fenom::AUTO_RELOAD | Fenom::FORCE_INCLUDE);
|
||
```
|
||
|
||
**Note**
|
||
By default all options disabled
|
||
|
||
## Extends
|
||
|
||
### Template providers
|
||
|
||
Бывает так что шаблны не хранятся на файловой сиситеме, а хранятся в некотором хранилище, например, в базе данных MySQL.
|
||
В этом случае шаблонизатору нужно описать как забирать шаблоны из хранилища, как проверять дату изменения шаблона и где хранить кеш шаблонов (опционально).
|
||
Эту задачу берут на себя Providers, это объекты реальзующие интерфейс `Fenom\ProviderInterface`.
|
||
|
||
### Callbacks and filters
|
||
|
||
#### Before compile callback
|
||
|
||
```php
|
||
$fenom->addPreFilter(function () { /* ... */ });
|
||
```
|
||
|
||
#### Tag filter callback
|
||
|
||
#### Filter callback
|
||
|
||
#### After compile callback
|
||
|
