Häufige Annahme

tint formats AddSource as a standard key-value attribute at the end of the log line matching slog.TextHandler conventions.

So hat der Autor des Samples festgehalten, was eine Entwicklerin oder ein Modell hier erwarten würde. Der Vertrag darunter ist das, was tatsächlich lief.

Contract

• tint.NewTextHandler formats source code locations directly between the level badge and log message as a faint prefix instead of a trailing key-value pair, and allows complete suppression or replacement via ReplaceAttr
• ReplaceAttr receives *slog.Source for slog.SourceKey and returning an empty slog.Attr removes the source prefix completely without leftover spacing
• ReplaceAttr intercepts built-in slog keys including slog.LevelKey, slog.MessageKey, and slog.TimeKey for custom level tagging, payload rewriting, or timestamp omission
• Nested WithGroup handlers and inline slog.Group attributes pass their full group hierarchy to ReplaceAttr while tint formats keys with dot notation and prunes empty groups entirely
• ReplaceAttr can dynamically return tint.Attr or tint.Err to conditionally colorize attributes based on runtime values
