FastLingo is a command-line tool designed to translate iOS app metadata using a variety of translation sources. It is built on top of Fastlane and Deliver. FastLingo is currently supports the following translation sources:

• Google Cloud Translation API

Full documentation can be found here.

Features

• Multilingual app metadata translation.
• Configurable translation sources.
• Translation caching for enhanced performance and fewer API calls.
• Seamless integration with Fastlane metadata folder structure.

Installation

To install FastLingo, execute the following command:

pip install fastlingo

Configuration

Before using FastLingo, configure your preferred translation source by establishing API keys and endpoints. Generate a template configuration file by executing:

fastlingo init

This action creates a FastLingo.toml file in the current directory, which can then be edited to include your API keys and endpoints. For example, to configure the Google Cloud Translation API, add the following to your configuration file:

translation_service = "google"
source_language = "ENGLISH"
target_languages = [ "AUTO",]
metadata_folder = "your/metadata/folder"
fields_to_translate = [ "name", "description" ]

[api_keys]
google = "service/account/key.json"

[cache]
cache_folder = ".fastlingo-cache"
cache_enabled = true

How to Use

To translate your app metadata, run:

fastlingo translate

This will translate all the metadata fields specified in your configuration file for each target language.
