+// INVALID FILE — used to test the Nova issue matcher.

+// Open this file and run it with the "Current Zig File" task (zig run).
+// The compiler will report an error that the issue matcher captures:
+//
+//   error-example.zig:16:23: error: type 'u8' cannot represent integer value '300'
+//
+// This verifies that the regexp  ^(.+?):(\d+):(\d+):\s*(error|warning):\s*(.+)$
+// correctly extracts file, line, column, severity, and message.
