# Localization
|
||
|
|
|
||
|
|
Send is localized in over 50 languages. We use the [fluent](http://projectfluent.org/) library and store our translations in [FTL](http://projectfluent.org/fluent/guide/) files in `public/locales/`. `en-US` is our base language, and other languages are managed by [pontoon](https://pontoon.mozilla.org/projects/test-pilot-firefox-send/).
|
||
|
|
|
||
|
|
## Process
|
||
|
|
|
||
|
|
Strings are added or removed from [public/locales/en-US/send.ftl] as needed. Strings **MUST NOT** be *changed* after they've been commited and pushed to master. Changing a string requires creating a new ID with a new name (preferably descriptive instead of incremented) and deletion of the obsolete ID. It's often useful to add a comment above the string with info about how and where the string is used.
|
||
|
|
|
||
|
|
Once new strings are commited to master they are available for translators in Pontoon. All languages other than `en-US` should be edited via Pontoon. Translations get automatically commited to the github master branch.
|
||
|
|
|
||
|
|
### Activation
|
||
|
|
|
||
|
|
The development environment includes all locales in `public/locales` via the `L10N_DEV` environment variable. Production uses `package.json` as the list of locales to use. Once a locale has enough string coverage it should be added to `package.json`.
|
||
|
|
|
||
|
|
## Code
|
||
|
|
|
||
|
|
In `app/` we use the `state.translate()` function to translate strings to the best matching language base on the user's `Accept-Language` header. It's a wrapper around fluent's [MessageContext.format](http://projectfluent.org/fluent.js/fluent/MessageContext.html). It works the same for both server and client side rendering.
|
||
|
|
|
||
|
|
### Examples
|
||
|
|
|
||
|
|
```js
|
||
|
|
// simple string
|
||
|
|
const finishedString = state.translate('downloadFinish')
|
||
|
|
// with parameters
|
||
|
|
const progressString = state.translate('downloadingPageProgress', {
|
||
|
|
filename: state.fileInfo.name,
|
||
|
|
size: bytes(state.fileInfo.size)
|
||
|
|
})
|
||
|
|
```
