  3. KURL • Kinetic Uniform Request Language • KURL is a domain-specific language (DSL) written in Ruby • DSL? • A language designed to solve a specific set of problems • =MIN(A2:A7) • KURL creates catalogs and service items in Kinetic Request • Hides complexity of forms and relationships

  4. KURL History • Previous Names • Shayne-alyzer, Template Generator, Accelerator, etc. • Ruby source to JAR file • Klink to ars models to Remedy Pure Java API • More and more comprehensive

  5. KURL Components • KURL Code • Ruby code containing functions made available in KURL • service_item, page, event, etc. • KURL Jar • Commands executed in command prompt with the kurl.jar • build_catalog, retrieve_service_item, etc

  6. KURL on Community

  7. KURL Components Execute Ruby Request Server Ruby (.rb) file kurl.jar API Calls Print Ruby

  8. Uses for KURL • Import/Export format • Human readable • Suitable for version control • Automate service item development • Generate KURL code from other sources (csv, database, etc.) • Generate KURL code from a service item • Catalog provisioning (service providers)

  9. Uses for KURL

  10. Uses for KURL • Alternative method of service item development • Text editing rather than point-and-click • Reduced duplication • Leverage Ruby features to aid development • Version control • https://github.com/kineticdata/demo-acme

  11. Hello World • Ruby file • Command prompt

  12. About Ruby • Object oriented • Dynamic typing • Clean syntax • Powerful features • Designed for developer happiness • JRuby • Runs on Java platform

  13. Ruby • http://www.ruby-lang.org/

  14. JRuby • http://jruby.org/

  15. Development with KURL • Goals • Adaptable and maintainable • Simplicity • More efficient development • Track development

  16. Development with KURL • Generate a template service item • Look and feel • Common elements • Export template to KURL code • Break into reusable functions • Store reused values as ruby variables

  17. Template Service Item

  18. Template Service Item

  19. Template Service Item

  20. KURL Templates • A piece of KURL code wrapped in a function • Reducing duplication of common behavior • Further abstraction of KURL functions • Created 3 reusable code templates • Standard header – configuration items of service item • Standard content page – standard content at top of request • Standard footer – confirmation page

  21. KURL Templates

  22. KURL Templates Templates • DSL on top of a DSL • The domain is your service items KURLCode Remedy API

  23. Using KURL Templates

  24. Using KURL Templates

  25. Ruby Variables • Store commonly used values as variables • Refer to variables throughout KURL code • Examples • Company name • Web server URL

  26. Ruby Variables

  27. Ruby Variables • Added variables to our templates file

  28. More Ruby • Looping over KURL code • Generate data for portal development • Conditionals to generate dynamic content • Conditionally include templates

  29. Version Control Sample
