| 5 | == Using the static Resource Bundles == | ||
| 6 | |||
| 7 | * Stop your XWiki instance | ||
| 8 | * Unjar the ##WEB-INF/lib/xwiki-core-*.jar## file (it was named ##xwiki.jar## in old versions) in ##WEB-INF/classes## and remove it from ##WEB-INF/lib## | ||
| 9 | * Edit the ##WEB-INF/classes/ApplicationResources*.properties## Resource Bundle files by adding the key/value pairs you need for your application. | ||
| 10 | * In your document, use the following to get the value associated with a key: | ||
| 11 | |||
| 12 | {{code}} | ||
| 13 | $msg.get("key") | ||
| 14 | {{/code}} | ||
| 15 | |||
| 16 | This will get the value from the Resource Bundle corresponding to the current language you are using in XWiki. | ||
| 17 | |||
| 18 | == Using properties located in XWiki pages == | ||
| 19 | |||
| 20 | {{warning}} | ||
| 21 | The features described below are only available in XWiki 1.0 Beta 4 and above. The ability to parametrize the resource string is available only in XWiki 1.0 Beta 5 and above. | ||
| 22 | {{/warning}} | ||
| 23 | |||
| 24 | * Create a page that will host your key/value pairs. | ||
| 25 | * Enter all the key/value pairs in that page (use the wiki editor). For example: | ||
| 26 | |||
| 27 | {{code}} | ||
| 28 | greeting=hello | ||
| 29 | welcome=Welcome | ||
| 30 | withparams=I can {0} pass {1} {2} params too using the Java MessageFormat syntax | ||
| 31 | {{/code}} | ||
| 32 | |||
| 33 | * Do the same for all the translations you want. | ||
| 34 | |||
| 35 | {{info}} | ||
| 36 | To enable multiple languages you'll need to go to the Administration page and set MultiLingual to true and list the different languages you wish to use in the Languages field. | ||
| 37 | {{/info}} | ||
| 38 | |||
| 39 | * Tell XWiki that your page is a Document Bundle by going to the Administration page, selecting the "Programming" icon and entering it in the "Internationalization Document Bundles" field. You can specify several pages, separated by commas. | ||
| 40 | |||
| 41 | {{info}} | ||
| 42 | When creating | ||
| 43 | {{/info}} | ||
| 44 | |||
| 45 | * Alternatively you can also specify the list of Internationalization Document Bundles in ##xwiki.cfg## under the key ##xwiki.documentBundles##. | ||
| 46 | * On the page where you want to use the internationalized message, use: | ||
| 47 | |||
| 48 | {{code}} | ||
| 49 | $msg.get("key") | ||
| 50 | $msg.get("key", ["param1", "param2", ...]) | ||
| 51 | {{/code}} | ||
| 52 | |||
| 53 | where ##key## is the key for the message to retrieve. Parameters can also be passed as is shown in the second syntax above. | ||
| 54 | |||
| 55 | == I18n of XWiki Objects == | ||
| 56 | |||
| 57 | This is currently not implemented (see our logged issue: [[XWIKI-69>>http://jira.xwiki.org/jira/browse/XWIKI-69]]). There are 2 workarounds you can use: | ||
| 58 | |||
| 59 | * Have several objects, one for each language, with a language field, and then decide which object to use (for example in a Class Sheet, based on the current language). | ||
| 60 | * Use Velocity scripting to do an IF in your object. For example, you could have: | ||
| 61 | |||
| 62 | {{code language="none"}} | ||
| 63 | #if ($context.language == "fr") | ||
| 64 | French texts | ||
| 65 | #else | ||
| 66 | Default texts | ||
| 67 | #end | ||
| 68 | {{/code}} |
