*Fun*ctional Ruby 🚀

An experimental toolbox for writing "functional" Ruby.

Alt Text

Motivation

In 2020 I started looking into functional programming and got really excited about having a Ruby library that would make programming in Ruby feel as much close as possible to using "pure" functional languages.

Features

Action first, data last

100% Curried

Placeholder

Definition container

Installation

Useful resources

Add this line to your application's Gemfile:

gem 'fun-ruby'

And then execute:

bundle install

Or install it yourself as:

gem install fun-ruby

Contributing

All kinds of contributions are welcome!

In case you don't really know where to start, just read the details down below 😉

Library structure

1) All the implemented modules are located under lib/fun_ruby/modules. Most of the modules have the names matching correspondent Ruby Core classes/modules. For example, if you are looking for the entry point of Array you will find it at lib/fun_ruby/modules/array.rb

2) A module entry point file contains only the module definition and a method being used to coerce an input to the object that the module works with.

3) Each implemented function has its own file. For instance Array#size is located under lib/fun_ruby/modules/array/size.rb

CLI

The library goes with a useful command line interface that will help you to add new modules and functions without typing much boilerplate.
