+# frozen_string_literal: true
+
+# This module provides a factory class for creating a Ruby parser instance.
+# It temporarily disables verbose mode to suppress compatibility warnings
+# when loading the "parser/current" library.
+#
+# Example warning for the release of Ruby 3.4.1:
+#   warning: parser/current is loading parser/ruby34, which recognizes
+#   3.4.0-compliant syntax, but you are running 3.4.1.
+#   Please see https://github.com/whitequark/parser#compatibility-with-ruby-mri.
+#
+# By disabling verbose mode, these warnings are suppressed to provide a cleaner
+# output and avoid confusion. The verbose mode is restored after the parser
+# instance is created to maintain the original behavior.
