Parse Windows .ini Format with Ruby

I didn't write this, I'm just posting it in case someone else finds it useful. I needed to parse a file that turned out to be windows .ini. gdsx in #ruby-lang came up with this for me.



  #thanks to gdsx in #ruby-lang

  def tame(input)

          tamed = {}



          # split data on city names, throwing out surrounding brackets

          input = input.split(/\[([^\]]+)\]/)[1..-1]



          # sort the data into key/value pairs

          input.inject([]) {|tary, field|

                  tary << field

                  if(tary.length == 2)

                          # we have a key and value; put 'em to use

                          tamed[tary[0]] = tary[1].sub(/^\s+/,'').sub(/\s+$/,'')

                          # pass along a fresh temp-array

                          tary.clear

                  end

                  tary

                  }



          tamed.dup.each { |tkey, tval|

                  tvlist = tval.split(/[\r\n]+/)

                  p tvlist

                  tamed[tkey] = tvlist.inject({}) { |hash, val|

                          k, v = val.split(/=/)

                          hash[k]=v

                          hash

                          }

                  }



          tamed

  end

here's what the input looks like



[Amsterdam]  

Address=Amstelveenseweg 438;1084 JH;Amsterdam



[Antwerp]  

Address=Uitbreidingstraat 4;4-600;Antwerp



[Austin]  

Address=4221 South Harbor Expressway, Suite 400;Austin, Texas 78746



[Baltimore / Smith]

City=Baltimore 

Address=225 Johnson Avenue;Baltimore, Maryland 21209-3600



[Baltimore / Calvert]

City=Baltimore

Address=151 South Belmont Street, Suite 2350;Baltimore, Maryland 21202-6832



[Bangkok]

Address=Unit 543, London Tower;495 North Sathorn Road, Yannawa, Sathorn Bangkok 45467

Country=Thailand



[Bergen]

Country=Norway  

City=Bergen

Address=Torgallmenningen 4B;PO Box 2153 Sentrum, N-5811;Bergen

here's the output



{"Bergen"=>{"City"=>"Bergen", "Country"=>"Norway", "Address"=>"Torgallmenningen 4B;PO Box 2153 Sentrum, N-5811;Bergen"}, "Antwerp"=>{"Address"=>"Uitbreidingstraat 4;4-600;Antwerp"}, "Baltimore / Smith"=>{"City"=>"Baltimore", "Address"=>"225 Johnson Avenue;Baltimore, Maryland 21209-3600"}, "Amsterdam"=>{"Address"=>"Amstelveenseweg 438;1084 JH;Amsterdam"}, "Bangkok"=>{"Country"=>"Thailand", "Address"=>"Unit 543, London Tower;495 North Sathorn Road, Yannawa, Sathorn Bangkok 45467"}, "Austin"=>{"Address"=>"4221 South Harbor Expressway, Suite 400;Austin, Texas 78746"}, "Baltimore / Calvert"=>{"City"=>"Baltimore", "Address"=>"151 South Belmont Street, Suite 2350;Baltimore, Maryland 21202-6832"}

Is this also an example of a state machine in Ruby?
