New ISO 3166-1 implementation for Pharo Smalltalk


If your application lists any of Yugoslavia, Czechoslovakia, South Yemen, USSR, Serbia and Montenegro countries then you have an obsolescence problem. The same as if it doesn't known about South Sudan, Jersey or East Timor.

Geopolitical map has changed, countries around the world have dissolved, merged and new ones were created. As of August 2015, ISO web site lists 249 official countries. Unfortunately their list is not made available free of charge, but there are a few reliable places where its lists is available (ex: Wikipedia).

To keed updated regarding world political situation and providing more features, I developed an ISO 3166-1 wrapper to access objects into a ISO3166 model. This is, including only information contained in the ISO standard, not calling codes, not language tags or other data located at external standards. Installation instructions, usage and reference links are provided in this document. Code is in the SmalltalkHub repository. The Metacello Configuration is accessible from the Pharo Configuration Browser, in Pharo 4 (released in 2015), or Pharo catalog in Pharo 5 (to be released in 2016).

Documentation is available in PDF format. Suggestion, fixes and improvements are very welcome. Don’t hesitate to contribute if you want to add new features.
