Features

• Multi-language support with easy folder-based structure (supports subfolders!)
• Compatible and tested with Spigot/Paper 1.8–1.21+ (Java 11+ required)
• Automatically indentifies player's client language (if exists in your lang folders set as player lang)
• Per-player language selection and storage (YAML, SQLite, or MySQL)
• Cross-Server Sync with Redis support for BungeeCord/Velocity networks
• Automatic fallback translation to default language
• Custom actions on first join and when changing language (messages, sounds, commands, etc.)
• PlaceholderAPI integration for dynamic translations
• High Performance with Caffeine Cache and asynchronous storage
• API for developers to integrate with other plugins and systems

How it Works

• Each language is a folder which can have infinite translation files and subfolders.
• Uses PlaceholderAPI for dinamically show translation to your player based in player's selected language.
• If a translation key is missing, the default language key is used as fallback.

Commands & Permissions

iglanguages.admin - The main permission
iglanguages.updatechecker - Check updates on join

• /languages help - Shows help message
• /languages set <player> <lang> - Set a player's language
• /languages get <player> - Show a player's language
• /languages auto <player> - Auto detect player's language
• /languages list - List available languages
• /languages reload - Reload config and translations

Placeholders
PlaceholderAPI placeholders:

• %lang_(key)% - Shows translation for the key in the player's language (root files).
• %lang_(folder).(file)_(key)% - Shows translation for files in subfolders (e.g. %lang_menus.main_shop_title% for menus/main.yml).
• %lang_player% - Shows the player's current language
• %lang_player_(nick)% - Shows the specified player's language

Performance

• Uses Caffeine Cache (high-performance, thread-safe) to assist with heavy loads.
• All translations are loaded into memory at startup.
• Database access is minimal and highly optimized (HikariCP for SQL).
• Debounced YAML saving to reduce disk I/O.

API
For developers just look IGLanguagesAPI.java for more details. We have some useful methods (like getPlayerLang, getLangTranslation, getPlayerTranslation, etc). More informations on our GitHub page.
