Overview

Custom logger that accepts a ‘device`, `level`, and `formatter`. `formatter` can be any object that responds to `call`; a `Logger::Formatter` is used if the argument is not provided.

Here is an example formatter that uses ‘Oj` to format structured log messages:

require ‘oj’ OjFormatter = proc do |severity, datetime, progname, data|

data.merge!(
  name: progname,
  timestamp: datetime,
  severity: severity
)
Oj.dump(data, { mode: :compat, time_format: :xmlschema })

end

logger = RailwayIpc::Logger.new(STDOUT, Logger::INFO, OjFormatter)
