def io
  Thread.current[IO_ID] || Thread.main[IO_ID] || $stdout
end

.io=(io) ⇒ IO

Set the global io object. All loggers in the current thread will immediately begin using this new IO stream. It is the user’s responsibility to manage this IO object (like rewinding and closing).

Examples:

Setting the outputter to $stderr

Logify.io = $stderr

Using an IO object

io = StringIO.new
Logify.io = io

Parameters:

  • io (IO) —

    the IO object to output to

Returns:

  • (IO)

end

.level=(id) ⇒ Fixnum

Set the global log level. All loggers in the current thread will immediately begin using this new log level.

Examples:

Setting the log level to :fatal

Logify.level = :fatal

Parameters:

  • id (Symbol) —
