These are both important points, but I think they fall outside the remit of a library for ISO 3166 country codes, which I wrote originally for use in circumstances where some other standard just says “an ISO 3166 country code”. If the country codes standard included (as ISO 639 language codes does) historical codes, it would be appropriate to include them in that library, but since it doesn’t, it requires a separate library. Quite how far one should go back in this separate library I cannot say, but there are obvious use cases for country /names/ for countries that ceased to exist before 1974 and which therefore have never had an ISO 3166 country code. * * * I’m currently working on ISO 639 which again will be a presentation of the standard as Haskell data types. It requires ISO 15924 Script codes. It’s irritating how these things have been standardised: the registry for ISO 639 is a different format from ISO 15924, and the former includes (presumably non-normatively) records for the script codes. In 639 ranges are specified with “..” but in 15924 they are simply mentioned in the names :-(. -- Jón Fairbairn jon.fairba...@cl.cam.ac.uk http://www.chaos.org.uk/~jf/Stuff-I-dont-want.html (updated 2012-10-07) ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
[Haskell-cafe] Country names and language names
Hi! I am working on an app in Yesod that craves I18N. A problem I've come across there is giving correct country and language names based on currently selected language. So far, I've used the Yesod I18N message approach, but a lot of hand coding is involved. The iso3166-country-codes [1] package at Hackage by Jon Fairbairn provides a start in the right direction, but an obvious improvement upon it would be to have a function or map that takes an ISO 639 code and an ISO 3166 code and gives the correct human-readable name for the country as per the chosen target language (the ISO 639 code), and another function/map for languages. It would alleviate coding those pesky country and language switchers a *lot*, among other things. Jon Fairbarn that coded the iso3166-country-codes package said in private correspondence that it seemed worthwhile doing, but he couldn't do it in his spare time, which is understandable. I am willing to do some of the stuff involved (I know Swedish, French and some Turkish in addition to the ubiquitous English), but obviously it's too big a project for one man to handle (what with all the c'n'p involved :) ). I feel that this should be done, since it seems it isn't yet. I am inexperienced in coordinating such endeavours, though, so I would like to share that task at least to begin with, if possible. Any thoughts?

When you include obsolete names, there should be some way to create a list of current countries, e.g. for selection of the country, where someone lives, from a menu. Something like this: map isCurrentlyExisting listOfAllCountriesThatEverExisted Or you create a list of current countries and a list of obsolete countries.
