Locale::Language(3pm) Perl Programmers Reference Guide Locale::Language(3pm) 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 cor- responding language name: $| = 1; # turn off buffering print "Enter language code: "; chop($code = <STDIN>); $lang = code2language($code); if (defined $lang) { print "$code = $lang "; } else { print "'$code' is not a valid language code! "; } KNOWN BUGS AND LIMITATIONS
o 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. o Currently just supports the two letter language codes - there are also three-letter codes, and numbers. Would these be of any use to anyone?
