NAME

6       Data::Page::Pageset - change long page list to be shorter and well
7       navigate
8

DESCRIPTION

10       Pages number can be very high, and it is not comfortable to show user
11       from the first page to the last page list. Sometimes we need split the
12       page list into some sets to shorten the page list, the form is like:
13
14        1-6 7-12 13 14 15 16 17 18 19-24 25-30 31-36 37-41
15
16       the first two part indicats the two pagesets, and in current pageset,
17       we provide the normal page list from the first one to the last one, and
18       provide the rest pagesets to indicate the pages scope.
19
20       In this module, you can specify the pages_per_set or max_pagesets for
21       fine showing.

SYNOPSIS

24        use Data::Page::Pageset;
25        # we use Data::Page object, so do prepare
26        my $page = Data::Page->new($total_entries, $entries_per_page, $current_page);
27        # create the pageset object
28        my $pageset = Data::Page::Pageset->new( $page );
29        my $pageset = Data::Page::Pageset->new( $page, 12 );
30        my $pageset = Data::Page::Pageset->new( $page, { max_pagesets => $max_pagesets } );
31        my $pageset = Data::Page::Pageset->new( $page, { pages_per_set => $pages_per_set } );
32
33        # for using
34        foreach my $chunk ( $pageset->total_pagesets ){
35               if ( $chunk->is_current ){
36                       map { print "$_ " } ( $chunk->first .. $chunk->last );
37               }else{
38                       print "$chunk ";
39               }
40        }

METHODS

43       new()
44            # default page_per_set is 10
45            my $pageset = Data::Page::Pageset->new( $page );
46
47            # set the page_per_set to be 12
48            my $pageset = Data::Page::Pageset->new( $page, 12 );
49            # another the same by passing hashref
50            my $pageset = Data::Page::Pageset->new( $page, { pages_per_set => $pages_per_set } );
51
52            # set the max_pagesets value, default is 1
53            my $pageset = Data::Page::Pageset->new( $page, { max_pagesets => $max_pagesets } );
54            # if max_pagesets supplies, the pages_per_set setting will be ignore
55            my $pageset = Data::Page::Pageset->new( $page,
56                   { max_pagesets => $max_pagesets, pages_per_set => $pages_per_set } );
57
58           We must need $page(isa Data::Page) object.
59
60       max_pagesets( $number )
61            # set the max_pagesets value, and the $pageset's info will changed immediately
62            $pageset->max_pagesets( $number );
63
64       pages_per_set( $number )
65            # set the pages_per_set value, and the $pageset's info will changed immediately
66            $pageset->pages_per_set( $number );
67            my $present_setting = $pageset->pages_per_set();
68
69       $pageset->total_pages
70           return total pages' number.
71
72       $pageset->total_pagesets
73           return the actual pagesets number.
74
75       $pageset->first_pageset
76            my $chunk = $pageset->first_pageset;
77
78           return the first pageset, it's Data::Page::Pageset::Chunk object
79
80       $pageset->last_pageset
81            my $chunk = $pageset->last_pageset;
82
83           return the last pageset, it's Data::Page::Pageset::Chunk object
84
85       $pageset->current_pageset
86            my $chunk = $pageset->current_pageset;
87
88           return the current pageset which current page is in this pageset,
89           it's Data::Page::Pageset::Chunk object
90
91       $pageset->previous_pageset
92            my $chunk = $pageset->previous_pageset;
93
94           return the previous pageset, it's Data::Page::Pageset::Chunk object
95
96       $pageset->next_pageset
97            my $chunk = $pageset->next_pageset;
98
99           return the next pageset, it's Data::Page::Pageset::Chunk object

Data::Page::Pageset::Chunk object

102       a $pageset gives you some $chunk to do more stuff as you see above.
103       Here gives the $chunk methods
104
105       first
106            # return the first page number in this chunk
107            $chunk->first;
108
109       last
110            # return the last page number in this chunk
111            $chunk->last;
112
113       middle
114            # return the middle page number in this chunk
115            $chunk->middle;
116
117       pages
118            # return the pages number in this chunk
119            $chunk->pages;
120
121       is_current
122            # return true if this $chunk contains the current_page
123            $chunk->is_current;
124
125       as_string
126            # if this chunk is from page 3 to 7, then print '3-7'
127            print $chunk;
128            print $chunk->as_string;
129            print $chunk->as_string('-');
130
131            # you can change default '-' as:
132            print $chunk->as_string('~');
133
134           if the $chunk only contains one page, it will only return the page
135           number.
136
