TransformTree

TransformTree provides an API for buildng trees of closures and executing those closures on provided input. This allows users to output all possible combinations of their desired transformations. A small library of useful transformations is included.

Installation

Add this line to your application's Gemfile:

gem 'transform_tree'

And then execute:

$ bundle

Or install it yourself as:

$ gem install transform_tree

Usage

tree = TransformTree::TransformRoot.new
upcase = ->(o) { o.upcase }
downcase = ->(o) { o.downcase }
append_s = ->(o) { "#{o}s" }
append_exc = ->(o) { "#{o}!" }

tree.add_transform(upcase, downcase, TransformTree::Transforms.null)
tree.add_transform(append_s, append_exc, TransformTree::Transforms.null)
tree.execute('Woof')

 => ["WOOFs", "WOOF!", "WOOF", "woofs", "woof!", "woof", "Woofs", "Woof!", "Woof"]

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.
