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 & sunny.</description>
<temperature>18.3 C</temperature>
<wind>
<velocity>14 kts</velocity>
<direction>SSE</direction>
</wind>
</weather>
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
