This document discusses using Ruby for "folk programming" or casual programming projects outside of web applications. It provides 4 examples of using Ruby to integrate different programs: adding bookmarks to Safari from Hatena using RubyCocoa++; accessing Twitter from QuickSilver using RubyCocoa++; controlling Quartz Composer nodes from Gainer using RubyCocoa++++; and enhancing Vim with a Ruby plugin for the Refe reference tool. The document argues that Ruby is a nice "glue" for connecting different worlds and that its dynamic nature makes it useful for plugins and debugging without restarting applications. It encourages readers to create something useful and share it with others using Ruby outside the browser.

- 20. Easier than creating Great App
- 21. Like Remora
- 22. Lower Hurdle
- 23. But...
- 24. Seems difficult... by an untrained eye
- 25. No!
- 26. Use Ruby !
- 27. 4 Examples
- 28. Safari + Hatena Bookmark RubyCocoa++
- 29. def addEntry(entry) bmk = OSX::NSEntityDescription.objc_send( :insertNewObjectForEntityForName, 'Bookmark', :inManagedObjectContext, @context_) # title title = entry.elementsForName('title').first.stringValue bmk.setValue_forKey(title, 'title') # id eid = entry.elementsForName('id').first.stringValue.to_s pos = eid.rindex('-') eid = eid[pos+1,eid.size] bmk.setValue_forKey(eid, 'eid'); # links entry.elementsForName('link').each do |url| if url.attributeForName('rel').stringValue.compare('related') siteUrl = url.attributeForName('href').stringValue bmk.setValue_forKey(siteUrl, 'siteUrl') else bookmarkUrl = url.attributeForName('href').stringValue bmk.setValue_forKey('bookmarkUrl', 'bookmarkUrl') end end

- 37. Why Ruby ?
- 38. Nice Glue. Between Different Worlds. by St. Murse
- 39. Debuggability • Dynamic ! • reload from plugin itself def reload load ‘./itself.rb’ • no need to restart app end
- 40. Conclusion
- 41. Create Something Useful for You !
- 42. and Us !
- 43. out of Browser !
- 44. with Ruby !
