NAME
Locale::Language - ISO two letter codes for language identification (ISO 639)SYNOPSIS
use Locale::Language; $lang = code2language('en'); # $lang gets 'English' $code = language2code('French'); # $code gets 'fr' @codes = all_language_codes(); @names = all_language_names();
DESCRIPTION
The "Locale::Language" module provides access to the ISO two-letter codes for identifying languages, as defined in ISO 639. You can either access the codes via the ``conversion routines'' (described below), or via the two functions which return lists of all language codes or all language names.CONVERSION ROUTINES
There are two conversion routines: "code2language()" and "language2code()".- code2language()
- This function takes a two letter language code and returns a string which contains the name of the language identified. If the code is not a valid language code, as defined by ISO 639, then "undef" will be returned.
$lang = code2language($code);
- language2code()
- This function takes a language name and returns the corresponding two letter language code, if such exists. If the argument could not be identified as a language name, then "undef" will be returned.
$code = language2code('French');
The case of the language name is not important. See the section ``KNOWN BUGS AND LIMITATIONS'' below.
QUERY ROUTINES
There are two function which can be used to obtain a list of all language codes, or all language names:- all_language_codes()
- Returns a list of all two-letter language codes. The codes are guaranteed to be all lower-case, and not in any particular order.
- all_language_names()
- Returns a list of all language names for which there is a corresponding two-letter language code. The names are capitalised, and not returned in any particular order.
EXAMPLES
The following example illustrates use of the "code2language()" function. The user is prompted for a language code, and then told the corresponding language name:$| = 1; # turn off buffering print "Enter language code: "; chop($code = <STDIN>); $lang = code2language($code); if (defined $lang) { print "$code = $lang\n"; } else { print "'$code' is not a valid language code!\n"; }
KNOWN BUGS AND LIMITATIONS
- *
- In the current implementation, all data is read in when the module is loaded, and then held in memory. A lazy implementation would be more memory friendly.
- *
- Currently just supports the two letter language codes - there are also three-letter codes, and numbers. Would these be of any use to anyone?
