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.
