Custom Levels

With this release of Log, you can now style your custom level to your liking!

// Define a new level
const SuccessLevel = log.InfoLevel + 1

// Create a style
styles := log.DefaultStyles()
styles.Levels[SuccessLevel] = lipgloss.NewStyle().
    SetString("SUCCESS").
    Bold(true).
    Foreground(lipgloss.Color("42"))

// Set the styles on the default logger
log.SetStyles(styles)

// Define your custom func
func Success(msg string, args ...any) {
	log.Default().Log(SuccessLevel, msg, args...)
}

Along with that, this release includes some important bug fixes detailed below.

This new release of Log adds support for log/slog, and per-instance styles, and includes bug fixes. You can now use Log as a log/slog handler in your applications. Log comes with its own JSON and Logfmt formatters, on the other hand, Slog uses different handlers for these formats.

Breaking Changes!

• Bump the minimum GoLang version to 1.19
• Change the default timestamp key from ts to time to match log/slog
• Change the default level key from lvl to level to match log/slog
• ParseLevel() now returns an error if parse failed to find a level in string
• Default levels values changed to be increments of 4 i.e. DebugLevel = -4, InfoLevel = 0, WarnLevel = 4, ...
• Global styles are replaced with DefaultStyles() and SetStyles()
