Class FuzzySymbolSearch

java.lang.Object
org.ek9lang.compiler.search.FuzzySymbolSearch
public final class FuzzySymbolSearch extends Object
Provides fuzzy symbol search functionality using Levenshtein distance. Used to generate "Did you mean?" suggestions when symbols cannot be resolved.

This class searches scopes and aggregates for symbols with names similar to a target name, returning the best matches ordered by similarity (lowest cost first).

Callers should check whether fuzzy suggestions are enabled (E2+ error level) before invoking these methods, via ErrorListener.isFuzzySuggestionsEnabled().
