An example Ruby program to demonstrate the "pure function as an object" pattern.

Pure Function As An Object (PFAAO) Pattern Demonstration

This is a tiny project to demonstrate the PFAAO pattern. It converts a JSON document to an XML document. The accompanying article article is available here: http://www.rubypigeon.com/posts/the-pure-function-as-an-object-pfaao-pattern/

Running The Code

First, install the dependencies with:

bundle install

Then run the code with:

bundle exec ruby convert.rb

Acknowledgements

The input.json data set comes from JSON Studio website:

This pattern is inspired and influenced by all of Rich Hickey's Clojure talks and Casey Muratori's API design talks.
