Method Summary
-
clear() public static
Destroys all translator instances and creates a new empty translations collection.
-
config() public static
Registers a callable object that can be used for creating new translator instances for the same translations domain. Loaders will be invoked whenever a translator object is requested for a domain that has not been configured or loaded already.
-
defaultFormatter() public static
Sets the name of the default messages formatter to use for future translator instances.
-
defaultLocale() public static
This returns the default locale before any modifications, i.e. the value as stored in the
intl.default_locale
PHP setting before any manipulation by this class. -
getDefaultFormatter() public static
Returns the currently configured default formatter. -
getDefaultLocale() public static
Returns the default locale. -
getLocale() public static
Will return the currently configure locale as stored in the
intl.default_locale
PHP setting. -
getTranslator() public static
Returns an instance of a translator that was configured for the name and locale. -
locale() public static
Sets the default locale to use for future translator instances. This also affects the
intl.default_locale
PHP setting. -
setDefaultFormatter() public static
Sets the name of the default messages formatter to use for future translator instances. By default the
default
andsprintf
formatters are available. -
setLocale() public static
Sets the default locale to use for future translator instances. This also affects the
intl.default_locale
PHP setting. -
setTranslator() public static
Sets a translator. -
translator() public static
Returns an instance of a translator that was configured for the name and passed locale. If no locale is passed then it takes the value returned by the
getLocale()
method. -
translators() public static
Returns the translators collection instance. It can be used for getting specific translators based of their name and locale or to configure some aspect of future translations that are not yet constructed.
-
useFallback() public static
Set if the domain fallback is used.
Method Detail
clear() public static ¶
clear( )
Destroys all translator instances and creates a new empty translations collection.
config() public static ¶
config( string $name , callable $loader )
Registers a callable object that can be used for creating new translator instances for the same translations domain. Loaders will be invoked whenever a translator object is requested for a domain that has not been configured or loaded already.
Registering loaders is useful when you need to lazily use translations in multiple
different locales for the same domain, and don't want to use the built-in
translation service based of gettext
files.
Loader objects will receive two arguments: The domain name that needs to be
built, and the locale that is requested. These objects can assemble the messages
from any source, but must return an Aura\Intl\Package
object.
Example:
use Cake\I18n\MessagesFileLoader; I18n::config('my_domain', function ($name, $locale) { // Load src/Locale/$locale/filename.po $fileLoader = new MessagesFileLoader('filename', $locale, 'po'); return $fileLoader(); });
You can also assemble the package object yourself:
use Aura\Intl\Package; I18n::config('my_domain', function ($name, $locale) { $package = new Package('default'); $messages = (...); // Fetch messages for locale from external service. $package->setMessages($message); $package->setFallback('default'); return $package; });
Parameters
- string $name
- The name of the translator to create a loader for
- callable $loader
A callable object that should return a Package instance to be used for assembling a new translator.
defaultFormatter() public static ¶
defaultFormatter( string|null $name null )
Sets the name of the default messages formatter to use for future translator instances.
By default the default
and sprintf
formatters are available.
If called with no arguments, it will return the currently configured value.
Deprecated
Parameters
- string|null $name optional null
- The name of the formatter to use.
Returns
The name of the formatter.
defaultLocale() public static ¶
defaultLocale( )
This returns the default locale before any modifications, i.e.
the value as stored in the intl.default_locale
PHP setting before
any manipulation by this class.
Deprecated
Returns
getDefaultFormatter() public static ¶
getDefaultFormatter( )
Returns the currently configured default formatter.
Returns
The name of the formatter.
getDefaultLocale() public static ¶
getDefaultLocale( )
Returns the default locale.
This returns the default locale before any modifications, i.e.
the value as stored in the intl.default_locale
PHP setting before
any manipulation by this class.
Returns
getLocale() public static ¶
getLocale( )
Will return the currently configure locale as stored in the
intl.default_locale
PHP setting.
Returns
The name of the default locale.
getTranslator() public static ¶
getTranslator( string $name 'default' , string|null $locale null )
Returns an instance of a translator that was configured for the name and locale.
If no locale is passed then it takes the value returned by the getLocale()
method.
Parameters
- string $name optional 'default'
- The domain of the translation messages.
- string|null $locale optional null
- The locale for the translator.
Returns
The configured translator.
Throws
locale() public static ¶
locale( string|null $locale null )
Sets the default locale to use for future translator instances.
This also affects the intl.default_locale
PHP setting.
When called with no arguments it will return the currently configure
locale as stored in the intl.default_locale
PHP setting.
Deprecated
Parameters
- string|null $locale optional null
- The name of the locale to set as default.
Returns
The name of the default locale.
setDefaultFormatter() public static ¶
setDefaultFormatter( string $name )
Sets the name of the default messages formatter to use for future
translator instances. By default the default
and sprintf
formatters
are available.
Parameters
- string $name
- The name of the formatter to use.
setLocale() public static ¶
setLocale( string $locale )
Sets the default locale to use for future translator instances.
This also affects the intl.default_locale
PHP setting.
Parameters
- string $locale
- The name of the locale to set as default.
setTranslator() public static ¶
setTranslator( string $name , callable $loader , string|null $locale null )
Sets a translator.
Configures future translators, this is achieved by passing a callable as the last argument of this function.
Example:
I18n::setTranslator('default', function () { $package = new \Aura\Intl\Package(); $package->setMessages([ 'Cake' => 'Gâteau' ]); return $package; }, 'fr_FR'); $translator = I18n::getTranslator('default', 'fr_FR'); echo $translator->translate('Cake');
You can also use the Cake\I18n\MessagesFileLoader
class to load a specific
file from a folder. For example for loading a my_translations.po
file from
the src/Locale/custom
folder, you would do:
I18n::setTranslator( 'default', new MessagesFileLoader('my_translations', 'custom', 'po'), 'fr_FR' );
Parameters
- string $name
- The domain of the translation messages.
- callable $loader
A callback function or callable class responsible for constructing a translations package instance.
- string|null $locale optional null
- The locale for the translator.
translator() public static ¶
translator( string $name 'default' , string|null $locale null , callable $loader null )
Returns an instance of a translator that was configured for the name and passed
locale. If no locale is passed then it takes the value returned by the getLocale()
method.
This method can be used to configure future translators, this is achieved by passing a callable as the last argument of this function.
Example:
I18n::setTranslator('default', function () { $package = new \Aura\Intl\Package(); $package->setMessages([ 'Cake' => 'Gâteau' ]); return $package; }, 'fr_FR'); $translator = I18n::translator('default', 'fr_FR'); echo $translator->translate('Cake');
You can also use the Cake\I18n\MessagesFileLoader
class to load a specific
file from a folder. For example for loading a my_translations.po
file from
the src/Locale/custom
folder, you would do:
I18n::translator( 'default', 'fr_FR', new MessagesFileLoader('my_translations', 'custom', 'po'); );
Deprecated
