26. WordPress Translation API
28. WordPress ❤ Language Packs • Translations are stored in wp-content/languages • Translations are auto-updated • Translations are installed on-the-fly when switching your site language • Translations are installed asynchronously during other updates
29. load_default_textdomain() https://developer.wordpress.org/reference/functions/ load_default_textdomain/ Core Translation API
30. $title = __( 'Dashboard' ); wp-admin/index.php:31 gettext Functions
31. Are language packs for plugins and themes a thing?
32. YES. And they work more or less the same as core’s.
33. Requirements • The plugin/theme uses a proper text domain registration • Text domain is the same as the plugin/theme slug • Exception for WordPress 4.6+ • The plugin/theme is hosted in the official WordPress directory • Nothing more.
34. Good to know • Follow the #meta-language-packs channel on Slack • Language packs are updated 30 minutes after a change • Languages packs are generated if a project is 95% or more translated
35. Good to know • Check the status by visiting the Language Packs page of your project on translate.wordpress.org
