Multiline Component Utilities

This package provides the ability to programmatically generate multi-line Component text, commonly used for debug information, recipe display, and similar purposes.

IComponentInfo

dev.anvilcraft.lib.v2.util.component.IComponentInfo – the component info interface, with a single method: addInto(MultilineComponentHelper helper).

Implementing classes:

• LiteralInfo(String value) – displays literal text
• DirectInfo(Component value) – displays a component
• TranslatableInfo(String key, Object... args) – translation key; args may include SequencedCollection ( automatically calls helper.list) or ItemEnchantments (automatically calls helper.enchantments)

MultilineComponentHelper

dev.anvilcraft.lib.v2.util.component.MultilineComponentHelper – a multi-line text builder.

• Construction: MultilineComponentHelper.create() uses default symbols (LF, tab, comma, square brackets, curly braces)
• Basic append: addln(Component) (with newline and indentation), append(Component)
• Indentation control: in() / out() to enter/exit indentation levels
• Collection display: list(Component head, SequencedCollection<T>, Function<T,IComponentInfo[]>) – automatically formats lists; single elements display without newlines, multiple elements are formatted
• Enchantment display: enchantments(Component head, ItemEnchantments) – displays an enchantment list
• Build: build() returns the resulting Component

Usage example:

MultilineComponentHelper helper = MultilineComponentHelper.create();
helper.addln(Component.literal("Hello"));
helper.in();
helper.addln(Component.literal("World"));
helper.out();
Component result = helper.build(); // "Hello\n    World"
