# Translation
## POEditor
Baby Buddy uses [POEditor](https://poeditor.com/) for translation contributions.
Interested contributors can [join translation of Baby Buddy](https://poeditor.com/join/project/QwQqrpTIzn)
for access to a simple, web-based frontend for adding/editing translation files
to the project.
## Manual
Baby Buddy has support for translation/localization. A manual translation
process will look something like this:
1. Set up a development environment (see [Development environment](development-environment.md)).
1. Run `gulp makemessages -l xx` where `xx` is a specific locale code in the
[ISO 639-1 format](https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes) (e.g.,
"il" for Italian or "es" for Spanish). This creates a new translation file at
`locale/xx/LC_MESSAGES/django.po`, or updates one if it exists.
1. Open the created/updated `django.po` file and update the header template
with license and contact info.
1. Start translating! Each translatable string will have a `msgid` value with
the string in English and a corresponding (empty) `msgstr` value where a
translated string can be filled in.
1. Once all strings have been translated, run `gulp compilemessages -l xx` to
compile an optimized translation file (`locale/xx/LC_MESSAGES/django.mo`).
1. To expose the new translation as a user setting, add the locale code to the
`LANGUAGES` array in the base settings file (`babybuddy/settings/base.py`).
1. Check if Plotly offers a translation (in `node_modules/plotly.js/dist/`) for
the language. If it does:
1. Add the Plotly translation file path to [`gulpfile.config.js`](https://github.com/babybuddy/babybuddy/tree/master/gulpfile.config.js)
in `scriptsConfig.graph`.
2. Build, collect, and commit the `/static` folder (see [`gulp updatestatic`](gulp-command-reference.md#updatestatic)).
1. Check if Moment offers a translation (in `node_modules/moment/locale/`) for
the language. If it does:
1. Add the Moment translation file path to [`gulpfile.config.js`](https://github.com/babybuddy/babybuddy/tree/master/gulpfile.config.js)
in `scriptsConfig.vendor`.
2. Build, collect, and commit the `/static` folder (see
[`gulp updatestatic`](gulp-command-reference.md#updatestatic)).
1. Run the development server, log in, and update the user language to test the
newly translated strings.
Once the translation is complete, commit the new files and changes to a fork
and [create a pull request](pull-requests.md) for review.

documentation section: [Translation](https://docs.djangoproject.com/en/4.0/topics/i18n/translation/).
