Class Ek9Keywords

java.lang.Object

org.ek9lang.compiler.support.Ek9Keywords

public final class Ek9Keywords
extends Object

THE source for EK9's word keywords, and for whether a keyword can still be used as a NAME. Use this rather than walking the lexer vocabulary again or hand-copying a list.

The two questions differ: the grammar's identifier rule deliberately admits many word keywords (sort, cat, filter, map, text, type, ...), so "is a keyword" is NOT "cannot be a name". isReservedWord(String) answers the second by parsing word <- 1 in a minimal program, once per word, cached - DERIVED from the grammar, never a list that drifts when the grammar changes.

Consolidated 2026-09-26 (front-end audit batch 9) from compiler-services CursorColumn (which now delegates here) and a cruder copy in SyntheticParameterNames that treated every keyword as reserved.
