Ruby XML Template (RXT) DSL

This repo contains code to accompany the article: How To Make A DSL, Hygienically

RXT is Ruby DSL for XML templates. It turns this:

xml version: '1.0', encoding: 'UTF-8'

weather at: @time.iso8601 do
  description @description
  temperature "#{@temp} C"
  wind do
    velocity "#{@wind_vel} kts"
    direction @wind_direction
  end
end

Into this:

<?xml version="1.0" encoding="UTF-8"?>
<weather at="2016-11-29T22:54:15+11:00">
  <description>Bright &amp; sunny.</description>
  <temperature>18.3 C</temperature>
  <wind>
    <velocity>14 kts</velocity>
    <direction>SSE</direction>
  </wind>
</weather>

Running The Code

First install the dependencies:

bundle install

Then you can run the DSL with:

bundle exec ruby run.rb

Or run the tests with

bundle exec rspec rxt_spec.rb
