  title: Implement Internationalization
  summary: Implement SilverStripe's internationalization system in your own modules.
  
  # Implementing Internationalization
  
  To find out about how to assist with translating SilverStripe from a users point of view, see the 
  [Contributing Translations page](/contributing/translations).
  
  ## Set up your own module for localization
  
  ### Collecting translatable text
  
  As a first step, you can automatically collect all translatable text in your module through the `i18nTextCollector` 
  task. See [i18n](../developer_guides/i18n#collecting-text) for more details.
  
  ### Import master files
  
  If you don't have an account on transifex.com yet, [create a free account now](http://www.transifex.com/signup). After 
  creating a new project, you have to upload the `en.yml` master file as a new "Resource". While you can do this through 
  the web interface, there's a convenient 
  [commandline client](http://support.transifex.com/customer/portal/topics/440187-transifex-client/articles) for this 
  purpose. In order to use it, set up a new `.tx/config` file in your module folder:
  	
  ```yaml
  [main]
  host = https://www.transifex.com
  
  
  [my-project.master]
  file_filter = lang/<lang>.yml
  source_file = lang/en.yml
  source_lang = en
  type = YML
  ```
  
  If you don't have existing translations, your project is ready to go - simply point translators to the URL, have them 
  sign up, and they can create languages and translations as required.
  
  ### Import existing translations
  
  In case you have existing translations in YML format, there's a "New language" option in the web interface. 
  Alternatively, use the [commandline client](http://support.transifex.com/customer/portal/topics/440187-transifex-client/articles).
  
  ### Export existing translations
  
  You can download new translations in YML format through the web interface, but that can get quite tedious for more than 
  a handful of translations. Again, the [commandline client](http://support.transifex.com/customer/portal/topics/440187-transifex-client/articles)
  provides a more convenient interface here with the `tx pull` command, downloading all translations as a batch.
  
  ### Merge back existing translations
  
  If you want to backport translations onto release branches, simply run the `tx pull` command on multiple branches. This 
  assumes you're adhering to the following guidelines:
  
   - For significantly changed content of an entity, create a new entity key
   - For added/removed placeholders, create a new entity
   - Run the `i18nTextCollectorTask` with the `merge=true` option to avoid deleting unused entities
     (which might still be relevant in older release branches)
  
  ### Converting your language files from 2.4 PHP format
  
  The conversion from PHP format to YML is taken care of by a module called 
  [i18n_yml_converter](https://github.com/chillu/i18n_yml_converter).
  
  ## Download Translations from Transifex.com
  
  We are managing our translations through a tool called [transifex.com](http://transifex.com). Most modules are handled 
  under the "silverstripe" user, see 
  [list of translatable modules](https://www.transifex.com/accounts/profile/silverstripe/).
  
  Translations need to be reviewed before being committed, which is a process that happens roughly once per month. We're 
  merging back translations into all supported release branches as well as the `master` branch. The following script 
  should be applied to the oldest release branch, and then merged forward into newer branches:
  	
  	:::bash	
  	tx pull
  
  	# Manually review changes through git diff, then commit
  	git add lang/*
  	git commit -m "Updated translations"
  
  <div class="notice" markdown="1">
  You can download your work right from Transifex in order to speed up the process for your desired language.
  </div>
  
  ## JavaScript Translations
  
  SilverStripe also supports translating strings in JavaScript (see [i18n](/developer_guides/i18n)), but there's a 
  conversion step involved in order to get those translations syncing with Transifex. Our translation files stored in 
  `mymodule/javascript/lang/*.js` call `ss.i18n.addDictionary()` to add files.
  	
  	:::js
  	ss.i18n.addDictionary('de', {'MyNamespace.MyKey': 'My Translation'});
  
  But Transifex only accepts structured formats like JSON.
  
  ```
  {'MyNamespace.MyKey': 'My Translation'}
  ```
  
  First of all, you need to create those source files in JSON, and store them in `mymodule/javascript/lang/src/*.js`. In your `.tx/config` you can configure this path as a separate master location.
  	
  	:::ruby
  	[main]
  	host = https://www.transifex.com
  
  	[silverstripe-mymodule.master]
  	file_filter = lang/<lang>.yml
  	source_file = lang/en.yml
  	source_lang = en
  	type = YML
  
  	[silverstripe-mymodule.master-js]
  	file_filter = javascript/lang/src/<lang>.js
  	source_file = javascript/lang/src/en.js
  	source_lang = en
  	type = KEYVALUEJSON
  
  Now you can upload the source files via a normal `tx push`. Once translations come in, you need to convert the source 
  files back into the JS files SilverStripe can actually read. This requires an installation of our 
  [buildtools](https://github.com/silverstripe/silverstripe-buildtools).
  
  	tx pull
  	(cd .. && phing -Dmodule=mymodule translation-generate-javascript-for-module)
  	git add javascript/lang/*
  	git commit -m "Updated javascript translations"
