How to add a translation#

You can translate Open Food Facts at https://translate.openfoodfacts.org thanks to the Crowdin platform. Please do not translate directly in the code, or your translations will be overwritten.

If you want to add a translatable string in the code:

modify the file with the .pot extension related to your context. Eg.

msgctxt "name_of_your_string"
msgid "Hello world!"
msgstr ""

modify the file en.po related to your context, to be sure at least an english string will be displayed before Crowdin send back all .po files (which can take several days). It should be the same code as the one from .pot + the english transaltion (see msgstr field). Eg.
```
msgctxt "name_of_your_string"
msgid "Hello world!"
msgstr "Hello world!"
```
use your new string with the lang() function. Eg. in a template file: [% lang('name_of_your_string') %]
if you want to test your modifications in your dev environnement:
- modify the fr.po files if you want to test in French; be aware it's just for test: these files will be overwritten by Crowdin. Eg. in French:
```
msgctxt "name_of_your_string"
msgid "Hello world!"
msgstr "Salut le monde!"
```
- don't forget to make build_lang to let docker take your modifications into account
