It was getting a bit lost halfway down the contributing/code instructions, in between the detailed git instructions. Also reordered the docs TOC for that folder by renaming the files.

# Implementing Internationalisation
|
|
|
|
To find out about how to assist with translating SilverStripe from a user's point of view, see the
|
|
[Contributing Translations page](/contributing/translations).
|
|
|
|
## Set up your own module for localisation
|
|
|
|
### 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 to import, 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 to YML
|
|
|
|
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
|
|
|
|
Then 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"
|
