RemoteTranslationLoader

RemoteTranslationLoader is a Ruby gem designed to dynamically fetch and load translation files (YAML format) into your Ruby or Ruby on Rails application. It supports multiple sources such as HTTP URLs, local files, and AWS S3, allowing you to seamlessly integrate external translations.

---

Features

• Fetch translations from multiple sources:
  • HTTP URLs
  • Local files
  • AWS S3 buckets
• Supports deep merging of translations with existing I18n backend.
• Namespace support for isolating translations.
• Dry-run mode to simulate translation loading.
• Rake tasks for easy integration with Rails applications.
• CLI tool for manual loading.

---

Installation

Add this line to your application's Gemfile:

gem 'remote_translation_loader'

And then execute:

bundle install

Or install it directly:

gem install remote_translation_loader

---

Usage

Basic Usage

1. HTTP Fetching

require 'remote_translation_loader'

urls = ['https://example.com/en.yml', 'https://example.com/fr.yml']
loader = RemoteTranslationLoader::Loader.new(urls)
loader.fetch_and_load

2. Local File Fetching

require 'remote_translation_loader'

files = ['/path/to/local/en.yml', '/path/to/local/fr.yml']
loader = RemoteTranslationLoader::Loader.new(files, fetcher: RemoteTranslationLoader::Fetchers::FileFetcher.new)
loader.fetch_and_load

3. AWS S3 Fetching

require 'remote_translation_loader'

bucket = 'your-s3-bucket'
s3_fetcher = RemoteTranslationLoader::Fetchers::S3Fetcher.new(bucket, region: 'us-east-1')
keys = ['translations/en.yml', 'translations/fr.yml']

loader = RemoteTranslationLoader::Loader.new(keys, fetcher: s3_fetcher)
loader.fetch_and_load

---

Advanced Options

Namespace Support

Add a namespace to group translations under a specific key:

loader.fetch_and_load(namespace: 'remote')
# Translations will be grouped under the `remote` key, e.g., `remote.en.some_key`

Dry-Run Mode

Simulate the loading process without modifying the I18n backend:

loader.fetch_and_load(dry_run: true)
# Outputs fetched translations to the console without loading them

---

CLI Usage

Install the gem globally and use the CLI tool:

remote_translation_loader https://example.com/en.yml /path/to/local/fr.yml

• The CLI fetches and loads the specified translations.
• Add the executable to your $PATH for easier access.

---

Rails Integration

1. Rake Task

Use the provided Rake task to fetch translations in a Rails application:

Add this to your Rakefile:

require 'remote_translation_loader'
load 'remote_translation_loader/tasks/remote_translation_loader.rake'

Run the task:

rake translations:load[https://example.com/en.yml,/path/to/local/fr.yml]

2. Automatic Loading

Add an initializer to load translations on application startup:

config/initializers/remote_translation_loader.rb

require 'remote_translation_loader'

urls = ['https://example.com/en.yml', '/path/to/local/fr.yml']
loader = RemoteTranslationLoader::Loader.new(urls)
loader.fetch_and_load(namespace: 'remote')
