This release fixes an issue when using the JSON logger as a slog handler logging error type messages. It ensures we extract the error from the message when the error does not implement json.Marshaler.

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()
