org.daiitech.naftah.utils.repl.BaseHighlighter
org.daiitech.naftah.utils.repl.CompositeHighlighter
All Implemented Interfaces:
org.jline.reader.Highlighter
public class CompositeHighlighter extends BaseHighlighter
A composite implementation of Highlighter that applies multiple highlighters in sequence and merges their results. If no additional highlighters are provided, it delegates to the original highlighter.

This class uses the builder pattern to allow fluent composition of multiple highlighters.

Example usage: 

 Highlighter original = ...;
 Highlighter custom1 = ...;
 Highlighter custom2 = ...;

 CompositeHighlighter highlighter = CompositeHighlighter.builder(original)
 .add(custom1)
 .add(custom2)
 .build();
