VERSION

This documents version 0.02 of WWW::Wikipedia::LangTitles corresponding to git commit 3c7983f8baf6a0e3cf7931bcaf470549c81a8635 released on Sun Dec 25 12:59:42 2016 +0900.

DESCRIPTION

This module retrieves the Wikipedia interwiki link titles from wikidata.org. It can be used, for example, to translate a term in English into other languages, or to get near equivalents.

FUNCTIONS

get_wiki_titles

   my $ref = get_wiki_titles ('Helium');

Returns a hash reference with all the articles in each language, indexed by the language. For example $ref->{th} will be equal to ฮีเลียม, the Thai title of the equivalent Wikipedia article.

The language of the original page can be specified like this:

   use utf8;
   my $from_th = get_wiki_titles ('ฮีเลียม', lang => 'th');

The URL is encoded using "uri_escape_utf8" in URI::Escape, so you must use character strings not byte strings (use "use utf8;" etc.)

An option "verbose" switches on verbose messages with any true value:

   my $ref = get_wiki_titles ($name, verbose => 1);

make_wiki_url

    my $url = make_wiki_url ('helium');

Make a URL for the Wikidata page. You will then need to retrieve the page and parse the JSON yourself. Use a second argument to specify the language of the page:

    use utf8;
    my $url = make_wiki_url ('ฮีเลียม', 'th');

The default is en for English.
