ring_buffer

ring_buffer provides a simple ring buffer implementation in Ruby. A ring buffer is a queue with a maximum capacity. When the capacity exceeds, the first element inserted is removed.

Add this line to your application's Gemfile:

gem 'ring_buffer'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ring_buffer

buffer = RingBuffer.new 2
buffer << 'first element'
buffer << 'second element'
buffer << 'third element'
p buffer
# ['second element', 'third element']

After checking out the repository, 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.

On my work station, I prefer to use a Docker image with Ruby installed instead of installing Ruby locally. Hence, any bundle … command can be prefixed with docker-compose run ring-buffer. For instance, running the tests is done with the command docker-compose run ring-buffer bundle exec rake spec.

This gem is a generalization of the wonderful work from Nimster and its ringbuffer gist.
