EverlaTweaker

A library mod providing data-driven control over item properties, including unbreakable items, colored names and descriptions, and fire/explosion-proof item drops.
Using these features is straightforward:

For colored names, simply add the item to the tag

everlatweaker:rainbow_name

For colored lore, first add the item to the tag

 everlatweaker:rainbow_lore

then write your key in the language file:

text.rainbow_lore.<mod_namespace>.<item_id>

and provide the localized text for that key, e.g.:

§mHee hee hee ha\n§r§oThis is an item

Colored descriptions support formatting via the § symbol, but line breaks must use the \n escape sequence. Also Supports Vanilla 16-color based on § codes

To make items or tools undestroyable, simply add a

everlatweaker:everlasting

tag to them.

The tags that separately make item fire immune and explosion immune is

everlatweaker:fire_resistant
everlatweaker:explosion_resistant
