24 * List a number of pagenames, optionally as table with various columns.
25 * This library relieves some work for these plugins:
27 * AllPages, BackLinks, LikePages, MostPopular, TitleSearch, WikiAdmin* and more
29 * It also allows dynamic expansion of those plugins to include more
30 * columns in their output.
32 * Column 'info=' arguments:
34 * 'pagename' _("Page Name")
35 * 'mtime' _("Last Modified")
37 * 'summary' _("Last Summary")
38 * 'version' _("Version")),
39 * 'author' _("Last Author")),
40 * 'locked' _("Locked"), _("locked")
41 * 'minor' _("Minor Edit"), _("minor")
42 * 'markup' _("Markup")
44 * 'creator' _("Creator")
46 * 'checkbox' selectable checkbox at the left.
49 * Special, custom columns: Either theme or plugin (WikiAdmin*) specific.
50 * 'remove' _("Remove")
51 * 'perm' _("Permission Mask")
53 * 'renamed_pagename' _("Rename to")
54 * 'ratingwidget', ... wikilens theme specific.
55 * 'custom' See plugin/_WikiTranslation
57 * Symbolic 'info=' arguments:
58 * 'all' All columns except the special columns
59 * 'most' pagename, mtime, author, size, hits, ...
60 * 'some' pagename, mtime, author
62 * FIXME: In this refactoring I (Jeff) have un-implemented _ctime, _cauthor, and
63 * number-of-revision. Note the _ctime and _cauthor as they were implemented
64 * were somewhat flawed: revision 1 of a page doesn't have to exist in the
65 * database. If lots of revisions have been made to a page, it's more than likely
66 * that some older revisions (include revision 1) have been cleaned (deleted).
69 * paging support: limit, offset args
70 * check PagePerm "list" access-type,
71 * all columns are sortable. Thanks to the wikilens team.
72 * cols > 1, comma, azhead, ordered (OL lists)
73 * ->supportedArgs() which arguments are supported, so that the plugin
74 * doesn't explictly need to declare it
75 * added slice option when the page_iter (e.g. ->_pages) is already sliced.
78 * fix sortby logic, fix multiple sortby and other paging args per page.
79 * info=relation,linkto nopage=1
80 * use custom format method (RecentChanges, rss, ...)
83 * fix memory exhaustion on large pagelists with old --memory-limit php's only.
84 * Status: improved 2004-06-25 16:19:36 rurban
