4 * List a number of pagenames, optionally as table with various columns.
5 * This library relieves some work for these plugins:
7 * AllPages, BackLinks, LikePages, MostPopular, TitleSearch, WikiAdmin* and more
9 * It also allows dynamic expansion of those plugins to include more
10 * columns in their output.
12 * Column 'info=' arguments:
14 * 'pagename' _("Page Name")
15 * 'mtime' _("Last Modified")
17 * 'summary' _("Last Summary")
18 * 'version' _("Version")),
19 * 'author' _("Last Author")),
20 * 'locked' _("Locked"), _("locked")
21 * 'minor' _("Minor Edit"), _("minor")
22 * 'markup' _("Markup")
24 * 'creator' _("Creator")
26 * 'checkbox' selectable checkbox at the left.
29 * Special, custom columns: Either theme or plugin (WikiAdmin*) specific.
30 * 'remove' _("Remove")
31 * 'perm' _("Permission Mask")
33 * 'renamed_pagename' _("Rename to")
34 * 'ratingwidget', ... wikilens theme specific.
35 * 'custom' See plugin/WikiTranslation
37 * Symbolic 'info=' arguments:
38 * 'all' All columns except the special columns
39 * 'most' pagename, mtime, author, size, hits, ...
40 * 'some' pagename, mtime, author
42 * FIXME: In this refactoring I (Jeff) have un-implemented _ctime, _cauthor, and
43 * number-of-revision. Note the _ctime and _cauthor as they were implemented
44 * were somewhat flawed: revision 1 of a page doesn't have to exist in the
45 * database. If lots of revisions have been made to a page, it's more than likely
46 * that some older revisions (include revision 1) have been cleaned (deleted).
49 * paging support: limit, offset args
50 * check PagePerm "list" access-type,
51 * all columns are sortable (Thanks to the wikilens team).
54 * rows arguments for multiple pages/multiple rows.
56 * ->supportedArgs() which arguments are supported, so that the plugin
57 * doesn't explictly need to declare it
58 * Status: already merged in some plugins calls
61 * list not as <ul> or table, but as simple comma-seperated list
63 * fix memory exhaustion on large pagelists.
64 * Status: fixed 2004-06-25 16:19:36 rurban but needs further testing.
