A script using MacRuby to export all the todos from Things projects into text files (my goal is to "copy and paste" them into 2DO.

thingsexporttodos.rb

#make sure you use macruby

framework "ScriptingBridge" #let's use the scripting bridge framework


# this is aweful - maybe a wrapper would be nice

# you can ge this BundleIdentifier using the mdls
# mdls -name kMDItemCFBundleIdentifier /Applications/Things.app
things =  SBApplication.applicationWithBundleIdentifier("com.culturedcode.things")

# lets get the projects that is what I am interested in
# the propertie is called "to dos" but it marshaled as "toDos"
# this is found nowhere in the documentation

#this is the weirdest thing - the property status does not return
# a string as defined in the documentation but a code.
# i had to "reverse engineer" this and I am not sure if it will
# work in all the systems

open_code = 1952737647

things.projects.each { |pr|  
  
  File.open("#{pr.name}.txt", 'w') { |f| 
    pr.toDos.each {|todo| f.puts todo.name if todo.status == open_code }
   } if pr.status == open_code
  
}

#that's all folks! - easy isn't it... :S
