Goal
roaring-rb‘s goal is to expose the full power of Roaring Bitmaps in Ruby with minimal overhead.
Installation
Add the roaring-rb gem to your Gemfile and run bundle install:
gem "roaring-rb"
Alternatively, you can install the gem manually:
gem install roaring-rb
Precompiled gems
We recommend installing the roaring-rb precompiled gems available for Linux, macOS, and Windows. Installing a precompiled gem avoids the need to compile from source code, which is generally slower and less reliable.
When installing the roaring-rb gem for the first time using bundle install, Bundler will automatically download the precompiled gem for your current platform. However, you will need to inform Bundler of any additional platforms you plan to use.
To do this, lock your Bundle to the required platforms you will need from the list of supported platforms below:
bundle lock --add-platform x86_64-linux # Standard Linux (e.g. Heroku, GitHub Actions, etc.)
bundle lock --add-platform x86_64-linux-musl # MUSL Linux deployments (i.e. Alpine Linux)
bundle lock --add-platform aarch64-linux # ARM64 Linux deployments (i.e. AWS Graviton2)
bundle lock --add-platform x86_64-darwin # Intel MacOS (i.e. pre-M1)
bundle lock --add-platform arm64-darwin # Apple Silicon MacOS (i.e. M1)
bundle lock --add-platform x64-mingw-ucrt # Windows
bundle lock --add-platform x64-mingw32 # Different Windows?
Usage
Lots of usage examples can be found in the documentation for Roaring::Bitmap.
Development
After checking out the repo, run bin/setup to install dependencies. Then, run rake to compile & 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. Version releases are automated by GH Actions.
