NAME Data::Page::FlickrLike − Generates flickr−like navigation links SYNOPSIS use Data::Page; use Data::Page::FlickrLike; my $page = Data::Page−>new(); $page−>total_entries($total_entries); $page−>entries_per_page($entries_per_page); $page−>current_page($current_page); print join (" ", map { $_ == 0 ? q{...} : qq{$_} } $page−>navigations); # 1*2 3 4 5 6 7 ... 76 77 # 1 2 ... 10 11 12 13*14 15 16 ... 76 77 # 1 2 ... 71 72 73 74 75 76 77* # Note: * means the current page DESCRIPTION Data::Page::FlickrLike is an extension to Data::Page to generate flickr‐like navigation links. METHODS navigations (Data::Page) This method gets an array reference consists of the number of pages. $nav = $page−>navigations It calculates: how may numbers should be displayed from the first page, how many numbers should be displayed form the last page, whether or not there’s a big enough gap between the first page and current page to put an ellipsis and more. As the name of this modules says, the array ref should make it easy to generate a "Flickr‐Like" navigation. It uses "0" for an ellipsis between two sets of page numbers. For example, if you have enough amount of items, navigations() returns like this: [ 1, 2, 3, 4, 5, 6, 7, 0, 76, 77 ] So, you need to put an exception to display an ellipsis(...) like this. for my $num ($page−>navigations) { if ($num == 0 ) { print "..."; } else { print qq{$_}; } } CONFIGURATION VARIABLES By default, navigation() generates an array reference to create pagination links exactly as the same as Flickr.com does. But if you do not like this behavior, you can tweak these configuration variables. $Data::Page::FlickrLike::InnerWindow or $page−>navigations({inner_window => $val}) Customises the number of links displayed at side of the current page. $Data::Page::FlickrLike::OuterWindow or $page−>navigations({outer_window => $val}) Customises the number of links displayed at the start and end of the page links. $Data::Page::FlickrLike::MinLength or $page−>navigations({min_length => $val}) Customises the minimum number of the links displayed when the current page at the first or last page. $Data::Page::FlickrLike::GlueLength or $page−>navigations({glue_length => $val}) Customises the minimum number of the links at the either side of the current page and the links at the first and last. For example, these "3g" and "4g" are displayed because of the glue length (= 2). 1 2 3 4 5 6* 7 8 9 ... 21 22 1 2 3g 4 5 6 7* 8 9 10 ... 21 22 1 2 3g 4g 5 6 7 8* 9 10 11 ... 21 22 1 2 ... 5 6 7 8 9* 10 11 12 ... 21 22 (* means a number of the current page) AUTHOR Masayoshi Sekimura LICENSE This library is free software; you can redistribute it and/or modify it under the same terms as Perl itself.
