Fly’s config lib

Fly’s Config Lib

A shared configuration library for Fly’s Minecraft mods providing JSON config management, registry helpers, and NBT pattern matching.

Features

• Load and save mod settings from a JSON file
• Automatically creates a default config file if none exists
• Detects when the config file is edited on disk and reloads it without restarting
• Backs up broken/corrupted config files with a timestamp before resetting to defaults
• Look up items, blocks, and entities by their in-game I
• Caches registry lookups so repeated lookups don’t slow things down
• Match items by their NBT data (enchantments, custom names, written book authors, etc.)
• Partial NBT matching — only the tags you specify need to match, the rest are ignored
• Exact NBT matching — the item must have exactly the tags specified, nothing more
• List NBT matching — check if an item has at least one of the specified enchantments/tags
• Strict list matching — check if an item has all of the specified enchantments/tags
• Numeric NBT values match regardless of internal type
• Map config keys to values using either exact strings or regex patterns
• Extract parts of a matched string via capture groups and reuse them in the mapped value
