Constructor & Destructor Documentation

__construct()

core_string_manager_standard::__construct	(		$otherroot,
			$localroot,
			$translist,
			$transaliases = []
	)

Create new instance of string manager.

Parameters

string	$otherroot	location of downloaded lang packs - usually $CFG->dataroot/lang
string	$localroot	usually the same as $otherroot
array	$translist	limit list of visible translations
array	$transaliases	aliases to use for the languages in the language selector

Member Function Documentation

get_key_suffix()

core_string_manager_standard::get_key_suffix ( )

protected

Returns cache key suffix, this enables us to store string + lang menu caches in local caches on cluster nodes.

We can not use prefix because it would cause problems when creating subdirs in cache file store.

Return values

string

get_language_dependencies()

core_string_manager_standard::get_language_dependencies

(

$lang

)

Returns list of all explicit parent languages for the given language.

English (en) is considered as the top implicit parent of all language packs and is not included in the returned list. The language itself is appended to the end of the list. The method is aware of circular dependency risk.

See also

self::populate_parent_languages()

Parameters

string

$lang

the code of the language

Return values

array

all explicit parent languages with the lang itself appended

get_list_of_countries()

core_string_manager_standard::get_list_of_countries	(		$returnall = false,
			$lang = null
	)

Returns a localised list of all country names, sorted by localised name.

Parameters

bool	$returnall	return all or just enabled
string	$lang	moodle translation language, null means use current

Return values

array

two-letter country code => translated name.

Implements core_string_manager.

get_list_of_currencies()

core_string_manager_standard::get_list_of_currencies

(

$lang = null

)

Returns localised list of currencies.

Parameters

string

$lang

moodle translation language, null means use current

Return values

array

currency code => localised currency name

Implements core_string_manager.

get_list_of_languages()

core_string_manager_standard::get_list_of_languages	(		$lang = null,
			$standard = 'iso6391'
	)

Returns a localised list of languages, sorted by code keys.

Parameters

string	$lang	moodle translation language, null means use current
string	$standard	language list standard iso6392: three-letter language code (ISO 639-2/T) => translated name iso6391: two-letter language code (ISO 639-1) => translated name

Return values

array

language code => translated name

Implements core_string_manager.

get_list_of_translations()

core_string_manager_standard::get_list_of_translations

(

$returnall = false

)

Returns localised list of installed translations.

Parameters

bool

$returnall

return all or just enabled

Return values

array

moodle translation code => localised translation name

Implements core_string_manager.

get_performance_summary()

core_string_manager_standard::get_performance_summary

(

)

Returns information about the core_string_manager performance.

Return values

array

get_revision()

core_string_manager_standard::get_revision

(

)

Returns string revision counter, this is incremented after any string cache reset.

Return values

int	lang string revision counter, -1 if unknown

Implements core_string_manager.

get_string()

core_string_manager_standard::get_string	(		$identifier,
			$component = '',
			$a = null,
			$lang = null
	)

Get String returns a requested string.

Parameters

string	$identifier	The identifier of the string to search for
string	$component	The module the string is associated with
string | object | array	$a	An object, string or number that can be used within translation strings
string	$lang	moodle translation language, null means use current

Return values

string

The String !

Implements core_string_manager.

load_component_strings()

core_string_manager_standard::load_component_strings	(		$component,
			$lang,
			$disablecache = false,
			$disablelocal = false
	)

Load all strings for one component.

Parameters

string	$component	The module the string is associated with
string	$lang
bool	$disablecache	Do not use caches, force fetching the strings from sources
bool	$disablelocal	Do not use customized strings in xx_local language packs

Return values

array

of all string for given component and lang

Implements core_string_manager.

load_deprecated_strings()

core_string_manager_standard::load_deprecated_strings ( )

protected

Parses all deprecated.txt in all plugins lang locations and returns the list of deprecated strings.

Static variable is used for caching, this function is only called in dev environment.

Return values

array

of deprecated strings in the same format they appear in deprecated.txt files: "identifier,component" where component is a normalised component (i.e. "core_moodle", "mod_assign", etc.)

populate_parent_languages()

core_string_manager_standard::populate_parent_languages (   $lang, array  $stack = array()  )

protected

Helper method that recursively loads all parents of the given language.

See also

self::get_language_dependencies()

Parameters

string	$lang	language code
array	$stack	list of parent languages already populated in previous recursive calls

Return values

array

list of all parents of the given language with the $lang itself added as the last element

reset_caches()

core_string_manager_standard::reset_caches

(

$phpunitreset = false

)

Clears both in-memory and on-disk caches.

Parameters

bool

$phpunitreset

true means called from our PHPUnit integration test reset

Implements core_string_manager.

string_deprecated()

core_string_manager_standard::string_deprecated	(		$identifier,
			$component
	)

Has string been deprecated?

Usually checked only inside get_string() to display debug warnings.

Parameters

string	$identifier	The identifier of the string to search for
string	$component	The module the string is associated with

Return values

bool	true if deprecated

Implements core_string_manager.

string_exists()

core_string_manager_standard::string_exists	(		$identifier,
			$component
	)

Does the string actually exist?

get_string() is throwing debug warnings, sometimes we do not want them or we want to display better explanation of the problem. Note: Use with care!

Parameters

string	$identifier	The identifier of the string to search for
string	$component	The module the string is associated with

Return values

boot	true if exists

Implements core_string_manager.

translation_exists()

core_string_manager_standard::translation_exists	(		$lang,
			$includeall = true
	)

Checks if the translation exists for the language.

Parameters

string	$lang	moodle translation language code
bool	$includeall	include also disabled translations

Return values

bool	true if exists

Implements core_string_manager.
