Description

Fixes a bug where tint.Attr used in ReplaceAttr doesn't reset ANSI colors for log levels below slog.LevelInfo (e.g., DEBUG), causing the color to "bleed" into subsequent log parts like source location.

Problem

When using tint.Attr in ReplaceAttr to colorize the slog.LevelKey attribute, the color was not being properly reset for levels < slog.LevelInfo. This resulted in the source location and message also being colored instead of just the level text.

Solution

Modified the condition in appendTintLevel to reset color when color >= 0 (i.e., when a custom color is applied via tint.Attr), regardless of the log level. Previously, color reset only happened for level >= slog.LevelInfo.

Change:

// Before
if !h.opts.NoColor && level >= slog.LevelInfo {
    buf.WriteString(ansiReset)
}

// After
if !h.opts.NoColor && (color >= 0 || level >= slog.LevelInfo) {
    buf.WriteString(ansiReset)
}
