I appreciate the effort and openness of metacpan, but their search is still pretty bad. To be clear, compare the results of the search for DBIx:Class::Source on SCO and metacpan. That’s why I made the following greasemonkey/dotjs script:
var obj = $(this);
var href = obj.attr('href');
var re = new RegExp('^/~([^/]+)/(.*)$');
this.href = href.replace(re, 'https://metacpan.org/module/$1/$2');
Put this in ~/.js/search.cpan.org.js to install it with dotjs. Feel free to extend it to work for more than just modules.
