Multiio

Delegates to Multiple IO sources (e.g. STDOUT, File)

Inspired by this answer on stackoverflow: https://stackoverflow.com/a/20422708/3384609

Also, if you want colors, STDOUT or STDERR must be put last, since it's the only two where colors are supposed to be output. But then, it will also output colors to your file.

Installation

Add this line to your application's Gemfile:

gem 'multiio'

And then execute:

$ bundle

Or install it yourself as:

$ gem install multiio

Usage

default_log_location = File.absolute_path(File.join(
  File.dirname(__FILE__), "..", "log", "vr2-worker-driver.log")
)
log_file_location = ENV['LOG_FILE_LOCATION']
if log_file_location == nil
  FileUtils.mkdir_p File.dirname(default_log_location)
  log_file_location = default_log_location
end
file = File.open(log_file_location, 'w')
@logger = Logger.new(MultiIO.new(file, STDOUT), 'daily')

Development

After checking out the repo, run bin/setup to install dependencies. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
