:globe_with_meridians: Internationalization Contribution Guide

reef-pi is now multilingual and we need your help to make the translations fit all the languages we purpose to choose.

How it works?

All the translations are stored in the CSV files in assets/translations. Each line describe a key/value pair. Those files are parsed and integrated into the Front-End application during the build process. The source language for all keys is the English, stored in assets/translations/en.csv.

The key maybe be simple or may describe a nested element with the use of namespaces. For example:

# this describe Loading translation as a global translation
loading,Loading
# output is : TranslationObject.loading
# This describe the Reload translation in the Configuration section in the admin panel
configuration:admin:reload,Reload
# output is : TranslationObject.configuration.admin.reload

Using namespaces give us more readability of where the translation is, mainly for people not familiar with front-end development or javascript.

If you want to dig into the code:

Csv to json parsing: build/translations/csv-json.js (called with loader.js)

Csv synchronization: build/translations/csv-sync.js (called with translations:sync)

The CSV synchronization make sure the translations files are synchronized beetween each others.

Front-end integration: jsx/utils/i18n.js

:suspect: How do i contribute?

Just fork the project, make a branch for the completion of your translation and create a pull request.

If you’re not familiar with all those aspects GitHub offers a web based csv editor. Here how you proceed from the reef-pi repository.

Note: If you want to add a sentence with a comma ‘,’ you’ll have to use quotes “ around the string to escape the sentence with the comma; otherwise the CSV format will not be respected.

:gift: I can provide a new language translation, how do i proceed?

First you have to create a file in the assets/translations folder with the ISO 639-1 code (2 letters one) of the language you want to provide. For example zh.csv for chinese. And insert the headers in it:

Key,Translation

Once it’s done you can use the command:

npm run translations:sync

And fill the document :smiley:
