rsplit

Divides string into substrings based on a delimiter (starting from right), returning an array of these substrings.

"1.2.3".split(".", 2)     #=> ["1", "2.3"]
"1.2.3".rsplit(".", 2)    #=> ["1.2", "3"]

Installation

Add this line to your application's Gemfile:

gem 'rsplit'

And then execute:

Or install it yourself as:

$ gem install rsplit

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake rspec 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.
