package org.apache.groovy.parser.antlr4.internal

Internal utilities for the ANTLR4 (Parrot) parser: ATN management, friendly error strategies (DescriptiveErrorStrategy fail-fast, RecoveringDescriptiveErrorStrategy multi-error), and related diagnostics (MissingDelimiterDiagnostic for relocated missing-closer carets; fallback wording lives on AbstractFriendlyErrorStrategy, including reserved keywords, a leading ?[ without a path to attach to, and a singleton expected-punctuation token after optional newlines are ignored). Reporting is one listener dispatch after locate/refine. Diagnostic helpers run only after recognition has already failed so they do not affect steady-state parse performance.
