Unlike the wiki-style freeform +Discussion pages, these comments are posted by a simple form, cannot later +be edited, and rss/atom feeds are provided of each page's comments. + +When using this plugin, you should also enable [[htmlscrubber]] and either +[[htmltidy]] or [[htmlbalance]].

As long as the recommended plugins are enabled, comment +authorship should hopefully be unforgeable by CGI users. + +The intention is that on a non-wiki site (like a blog) you can lock all +pages for admin-only access, then allow otherwise unprivileged (or perhaps +even anonymous) users to comment on posts. See the documentation of the +[[lockedit]] and [[anonok]] pages for details on locking down a wiki so +users can only post comments. + +Individual comments are stored as internal-use pages named something like +`page/comment_1`, `page/comment_2`, etc. These pages internally use a +`\[[!_comment]]` [[ikiwiki/directive]], and comment pages can be matched +using a special `postcomment()` [[ikiwiki/PageSpec]]. + +There are some global options for the setup file: + +* `comments_shown_pagespec`: pages where comments will be displayed inline, + e.g. `blog/*` or `!*/discussion`. +* `comments_open_pagespec`: pages where new comments can be posted, e.g. + `blog/* and created_after(close_old_comments)` or `!*/discussion` +* `comments_pagename`: if this is e.g. `comment_` (the default), then + comment pages will be named something like `page/comment_12` +* `comments_allowdirectives`: if true (default false), comments may + contain IkiWiki [[directives|ikiwiki/directive]] +* `comments_commit`: if true (default true), comments will be committed to + the version control system +* `comments_allowauthor`: if true (default false), anonymous commenters may + specify a name for themselves, and the \[[!meta author]] and + \[[!meta authorurl]] directives will not be overridden by the comments + plugin + +Known issues: + +* Needs code review +* The access control via postcomment() is rather strange (see [[discussion]] for more details) +* There is some common code cargo-culted from other plugins (notably inline and editpage) which + should probably be shared +* Joey doesn't think it should necessarily use internal pages (see [[discussion]]) +* Previews always say "unknown IP address" +* Add `COMMENTOPENID`: the authenticated/verified user name, if and only if it was an OpenID +* The default template should have a (?) icon next to unauthenticated users (with the IP address + as title) and an OpenID icon next to OpenIDs |
