Algs4ruby

The algs4ruby library is a ruby port of the algorithms, data structures and command-line clients in the [Algs4 repository]. The companion code to Algorithms 4th edition text book. For more information on the original library (in Java), the text book, or the accompanying Coursera course, please goto the [Algs4 repository].

The code in this repository is designed more for compatability to the original Java library than for being idiomatic ruby. If you are purely interested in a library more focussed on production code, than you might be better of using a different ruby library. The [algorithms] gem is aparently quite popular and makes use of C-extensions for extra speed. All that is not to say that the algs4ruby algorithms and data structures cannot be used in production code, but it's important to be aware that the ruby interpreter adds an overhead that may impact the overall performance of your code.

Installation

Add this line to your application's Gemfile:

gem 'algs4ruby'

And then execute:

$ bundle

Or install it yourself as:

$ gem install algs4ruby

Usage

You can use the entire code base in your own code by adding the algs4ruby to your class path and then requiring the gem:

require 'algs4ruby'

Most files are also an in-built testing client that can be run directly from the command-line by having ruby run just that file:

$ ruby lib/algs4_ruby/fundamentals/binary_search.rb whitelist.txt < input.txt

If you need to generate code documentation, than you make sure the library is class pathed and run:

$ yard

Development

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.

Contributing

Bug reports and pull requests are welcome on GitHub at the [algs4ruby repository]. Additional tests are especially welcome. If you contribute code, please make sure that it is sufficiently tested and make sure that it has no obvious styling issues by running [Flay], [Flog], and [Rubocop]:

$ flay your_file.rb
$ flog your_file.rb
$ rubocop your_file.rb

It's okay if your does not pass all the linting errors - they tend to find algorithms too complex - but make sure that there are no obvious issues.
