You can either access the codes via the \*(L"conversion routines\*(R" (described below), or via the two functions which return lists of all language codes or all language names. .SH "CONVERSION ROUTINES" .IX Header "CONVERSION ROUTINES" There are two conversion routines: \f(CW\*(C`code2language()\*(C'\fR and \f(CW\*(C`language2code()\*(C'\fR. .IP "\fIcode2language()\fR" 4 .IX Item "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 \s-1ISO\s0 639, then \f(CW\*(C`undef\*(C'\fR will be returned. .Sp .Vb 1 \& $lang = code2language($code); .Ve .IP "\fIlanguage2code()\fR" 4 .IX Item "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 \f(CW\*(C`undef\*(C'\fR will be returned. .Sp .Vb 1 \& $code = language2code('French'); .Ve .Sp The case of the language name is not important. See the section \*(L"\s-1KNOWN\s0 \s-1BUGS\s0 \s-1AND\s0 \s-1LIMITATIONS\s0\*(R" below. .SH "QUERY ROUTINES" .IX Header "QUERY ROUTINES" There are two function which can be used to obtain a list of all language codes, or all language names: .ie n .IP """all_language_codes()""" 4 .el .IP "\f(CWall_language_codes()\fR" 4 .IX Item "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. .ie n .IP """all_language_names()""" 4 .el .IP "\f(CWall_language_names()\fR" 4 .IX Item "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. .SH "EXAMPLES" .IX Header "EXAMPLES" The following example illustrates use of the \f(CW\*(C`code2language()\*(C'\fR function. The user is prompted for a language code, and then told the corresponding language name: .PP .Vb 1 \& $| = 1; # turn off buffering .Ve .PP .Vb 11 \& print "Enter language code: "; \& chop($code = ); \& $lang = code2language($code); \& if (defined $lang) \& { \& print "$code = $lang\en"; \& } \& else \& { \& print "'$code' is not a valid language code!\en"; \& } .Ve .SH "KNOWN BUGS AND LIMITATIONS" .IX Header "KNOWN BUGS AND LIMITATIONS" .IP "\(bu" 4 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. .IP "\(bu" 4 Currently just supports the two letter language codes \- there are also three-letter codes, and numbers.
