|
5 |
|
|
* Internationalization (i18n) package - translatable strings.
|
6 |
|
|
*
|
7 |
|
|
* Object oriented string translation using locale and textgroups. As opposed to core locale strings,
|
8 |
|
|
* all strings handled by this module will have a unique id (name), composed by several parts
|
9 |
|
|
*
|
10 |
|
|
* A string name or string id will have the form 'textgroup:type:objectid:property'. Examples:
|
11 |
|
|
*
|
12 |
|
|
* - 'profile:field:profile_name:title', will be the title for the profile field 'profile_name'
|
13 |
|
|
* - 'taxonomy:term:tid:name', will be the name for the taxonomy term tid
|
14 |
|
|
* - 'views:view_name:display_id:footer', footer text
|
15 |
|
|
*
|
16 |
|
|
* Notes:
|
17 |
|
|
* - The object id must be an integer. This is intended for quick indexing of some properties
|
18 |
|
|
*
|
19 |
|
|
* Some concepts
|
20 |
|
|
* - Textgroup. Group the string belongs to, defined by locale hook.
|
21 |
|
|
* - Location. Unique id of the string for this textgroup.
|
22 |
|
|
* - Name. Unique absolute id of the string: textgroup + location.
|
23 |
|
|
* - Context. Object with textgroup, type, objectid, property.
|
24 |
|
|
*
|
25 |
|
|
* Default language
|
26 |
|
|
* - Default language may be English or not. It will be the language set as default.
|
27 |
|
|
* Source strings will be stored in default language.
|
28 |
|
|
* - In the traditional i18n use case you shouldn't change the default language once defined.
|
29 |
|
|
*
|
30 |
|
|
* Default language changes
|
31 |
|
|
* - You might result in the need to change the default language at a later point.
|
32 |
|
|
* - Enabling translation of default language will curcumvent previous limitations.
|
33 |
|
|
* - Check i18n_string_translate_langcode() for more details.
|
34 |
|
|
*
|
35 |
|
|
* The API other modules to translate/update/remove user defined strings consists of
|
36 |
|
|
*
|
37 |
|
|
* @see i18n_string($name, $string, $langcode)
|
38 |
|
|
* @see i18n_string_update($name, $string, $format)
|
39 |
|
|
* @see i18n_string_remove($name, $string)
