NAME
Locale::Codes::Changes - details important changes after 2.07
3.10
Changed XXX_code2code behavior slightly
In previous versions, passing in the same code set for both code set arguments would automatically return undef. For example:
country_code2code('bo',LOCALE_CODE_ALPHA_2,LOCALE_CODE_ALPHA_2);
=> undef
This doesn't seem like reasonable behavior, so it has been changed to allow the same code set:
country_code2code('bo',LOCALE_CODE_ALPHA_2,LOCALE_CODE_ALPHA_2);
=> 'bo'
Note that if an invalid code is passed in, undef will still be returned:
country_code2code('bol',LOCALE_CODE_ALPHA_2,LOCALE_CODE_ALPHA_2);
=> undef
Added many semi-private routines
Previous versions had only two semi-private routines: rename_country and alias_code which had the ability to modify the internal data
in a couple very limited ways. It was requested (in an anonymous posting by someone named Steve and also by Steve Hay) that better
support for modifying internal data, so a full set of routines were added.
The full set of routines includes:
rename_country
rename_language
rename_currency
rename_script
add_country
add_language
add_currency
add_script
delete_country
delete_language
delete_currency
delete_script
add_country_alias
add_language_alias
add_currency_alias
add_script_alias
delete_country_alias
delete_language_alias
delete_currency_alias
delete_script_alias
rename_country_code
rename_language_code
rename_currency_code
rename_script_code
add_country_code_alias
add_language_code_alias
add_currency_code_alias
add_script_code_alias
delete_country_code_alias
delete_language_code_alias
delete_currency_code_alias
delete_script_code_alias
3.00
New maintainer
From 1997 to 2004, Locale::Codes was maintained by Neil Bowers. Unfortunately, no updates were made from June 2004 to January 2010.
During that time, a number of changes have been made to the standards since then, so the data included was out-of-date.
I contacted Neil to get his permission to assume maintenance of the module, and he kindly agreed.
All codes are generated from standards
All of the values returned by the various functions are now values directly from the standards. This means that the values returned in
the 2.xx series are not necessarily the same as the values returned here.
As an example, the ISO 3166 standard which lists country codes refers to the country associated with the code "bo" as "Bolivia,
Plurinational State of", so that is what is returned. In the 2.xx series, "Bolivia" was returned. Also, the country names vary from
one standard to another. So the code "bol" which is maintained by the United Nations returns the name of the country as "Bolivia
(Plurinational State of)". Some common aliases have been added, so you can still request a code associated with a county name
"Bolivia".
Since the data comes from the standards, some "incorrect" values are no longer supported. For example, 2.07 treated "Zaire" as an alias
for "Congo", but the country changed it's name, and "Zaire" is not in the standard, so it has been dropped in 3.00.
Added several code sets from standards
I've added the following code sets:
FIPS 10 country codes
Alpha-3 and Term language codes
Numeric currency codes
Locale::Script changed
In 2.xx, Locale::Script assigned scripts to country codes, which is NOT how it is done currently in the standards. It appears that an
older version of ISO 15924 did this, but I haven't found an old version to confirm that, and in any case, that is not the case in the
current standards.
As a result, the Locale::Script module is completely incompatible with the 2.xx version with respect to the types of codes it supports.
None of the old codes will work.
Added missing functions
I've added in some functions which were "missing" previously (since there was only one set of codes supported, the code2code functions
didn't apply):
language_code2code
currency_code2code
so the interfaces for each type of codes are consistent.
Dropped support for _alias_code
In Locale::Country, _alias_code was an allowed, but deprecated function which was documented to be supported in the 2.xx series. I've
removed it.
