Localizing

Given that CHT apps are used around the world, the Core Framework was designed with localization in mind. The Core Framework itself is available in English, French, Hindi, Nepali, Spanish, Swahili, and Indonesian.
In the app_settings.json file the default language for the application is set by the locale property, along with a separate default language for outgoing messages that are sent via SMS with the locale_outgoing property.
Additionally, languages available to the user can be enabled and disabled through the languages property which contains an array of objects. These objects should contain the locale and enabled properties representing respectively the 2 or 3 letter language code and whether that language should be enabled.

Translations

To modify some labels in the app add the key and modified label in a custom translations file in the translations folder. All the properties files use the format messages-{language-code}.properties, where the language code is the same 2-letter code used to identify the language in the application. For instance, for English, we would have a translations/messages-en.properties file.

New elements in CHT apps, such as tasks, targets, profiles, and forms should be localized as well. These labels should be included in the same custom translations properties file. If a translation is missing for the user’s language it will use that of the default language.

Here is an example, including both a modified label, and a new one:

translations/messages-{language-code}.properties

    [Application Text]
    contact.type.district_hospital = Community
    targets.assessments.title = Assessments Completed

Forms

Translations for XForms are defined within the forms themselves. The XLSForm notation is documented here, and would use the corresponding 2-character language codes.

Reports

Submitted forms are shown on the Reports tab, with each value in the report displayed alongside a label. The label for each value is represented by a key in the report.{form-name}.{field-name} format, which can be translated by including the key and translation in the language files. If the label is omitted in the translation the full key will show in the app.

Build

Custom translations from the properties files are added to the app with the upload-custom-translations action.

cht --local upload-custom-translations

Updated translations from forms need to be added with the actions to upload forms.
