# Fly’s Config Lib<\/p>\n
A shared configuration library for Fly’s Minecraft mods providing JSON config management, registry helpers, and NBT pattern matching.<\/p>\n
## Features
\n– Load and save mod settings from a JSON file
\n– Automatically creates a default config file if none exists
\n– Detects when the config file is edited on disk and reloads it without restarting
\n– Backs up broken\/corrupted config files with a timestamp before resetting to defaults
\n– Look up items, blocks, and entities by their in-game I
\n– Caches registry lookups so repeated lookups don’t slow things down
\n– Match items by their NBT data (enchantments, custom names, written book authors, etc.)
\n– Partial NBT matching \u2014 only the tags you specify need to match, the rest are ignored
\n– Exact NBT matching \u2014 the item must have exactly the tags specified, nothing more
\n– List NBT matching \u2014 check if an item has at least one of the specified enchantments\/tags
\n– Strict list matching \u2014 check if an item has all of the specified enchantments\/tags
\n– Numeric NBT values match regardless of internal type
\n– Map config keys to values using either exact strings or regex patterns
\n– Extract parts of a matched string via capture groups and reuse them in the mapped value<\/p>\n","protected":false},"excerpt":{"rendered":"
