Logger::Limit changes Logger behavior to only output previous log messages when a log of ERROR severity or higher occurs.
This gem is an implementation based on the idea proposed by the following blog post: https://www.komu.engineer/blogs/log-without-losing-context/log-without-losing-context
Add this line to your application's Gemfile:
gem 'logger-limit'And then execute:
$ bundle install
Or install it yourself as:
$ gem install logger-limit
WARNING: The current version of logger-limit does not correctly support parallelism due to how messages are saved. Basic tests with Process and Thread show that Process.fork seems to work correctly.
All you need to do is require logger-limit on your application:
require 'logger/limit'By requiring this gem, you are monkey patching Logger to store every log message with severity lower than Logger::ERROR. Once a log of severity Logger::ERROR or higher happens, all the stored messages will become visible in the correct order.
After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. 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.
