v2.1.0

Formatting

• Formattable prefix placeholders with the %{type:format} syntax, e.g. %{date:yyyy-MM-dd HH:mm:ss}

  • %{level:pad} can be used to make log levels a constant length (alias for %{level:5})
• New prefix placeholders:
  • %newline inserts a system-dependent newline
  • %{column:N} inserts padding until the column index N is reached
  • %loggerCompact inserts the logger name with a shortened namespace, e.g. Foo.Bar.Baz => FB.Baz
