A logger formatter to output each log with in line forcely

Rails default log formatter outputs backtrace in multiple lines, and it makes difficult to parse the log.

This log formatter replaces sthe line feed characters \n with \\n so that log messages will be in one line.

Add this line to your application's Gemfile:

gem 'oneline_log_formatter'

And then execute:

$ bundle

require 'logger'
require 'oneline_log_formatter'

logger = Logger.new(STDOUT)
logger.formatter = OnelineLogFormatter.new
logger.info("foo\nbar")

which outputs logs like

20150423T00:00:00+09:00 [INFO] foo\nbar

Note that the line feed character is converted into \n.

Configure at config/application.rb

config.logger.formatter = OnelineLogFormatter.new
