Maybe

Welcome to a very simple implementation of maybe in ruby. There aren't new types, just monkeypatching 🙊.

Installation

Until I get more feedback, I'm not doing a formal release. For now point to the github repo in your Gemfile.

# Gemfile
gem 'maybe', git: 'git@github.com:steven-solomon/maybe.git'

And then execute:

$ bundle

Usage

It's really simple just call :maybe on objects and pass a block you want to execute. There is also and :else method for handling nil.

Examples:

require 'maybe'

class Thing 
  def message
    "I worked"
  end
end

Thing.new.maybe { |t| puts t.message }.else { puts "I don't" }
# outputs "I worked"
  
nil.maybe { puts "I worked" }.else { puts "I don't" }
# outputs "I don't"

Feedback

If you have any problems, please don't hesitate to open an issue. Feedback is welcome.

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.
