How can I format logs in Ruby?

In Ruby, you can format logs using the Logger class. You can set the log format using a custom formatter.

Can you show me an example of a custom log formatter?

Sure! Here's a simple example:

require 'logger'

class CustomFormatter < Logger::Formatter
  def call(severity, time, progname, msg)
    "#{time.strftime('%Y-%m-%d %H:%M:%S')} [#{severity}] #{msg}\n"
  end
end

logger = Logger.new(STDOUT)
logger.formatter = CustomFormatter.new
logger.info('This is an info message')

What other options do I have for logging in Ruby?

You can also use gems like Log4r or Semantic Logger for more advanced logging features.
