|
|
|
|
This plugin adds "blog-style" comments. 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.
|
|
|
|
When using this plugin, you should also enable [[htmlscrubber]] and either [[htmltidy]]
|
|
or [[htmlbalance]]. Directives are filtered out by default, to avoid commenters slowing
|
|
down the wiki by causing time-consuming processing. As long as the recommended plugins
|
|
are enabled, comment authorship should hopefully be unforgeable by CGI users.
|
|
|
|
The plugin adds a new [[ikiwiki/PageSpec]] match type, `postcomment`, for use
|
|
with `anonok_pagespec` from the [[plugins/anonok]] plugin or `locked_pages` from
|
|
the [[plugins/lockedit]] plugin. Typical usage would be something like:
|
|
|
|
locked_pages => "!postcomment(*)"
|
|
|
|
to allow non-admin users to comment on pages, but not edit anything. You can also do
|
|
|
|
anonok_pages => "postcomment(*)"
|
|
|
|
to allow anonymous comments (the IP address will be used as the "author").
|
|
|
|
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 comments on the
|
|
[[sandbox]] will be called something like `sandbox/comment_12`
|
|
* `comments_allowdirectives`: if true (default false), comments may contain IkiWiki
|
|
directives
|
|
* `comments_commit`: if true (default true), comments will be committed to the version
|
|
control system
|
|
|
|
This plugin aims to close the [[todo]] item "[[todo/supporting_comments_via_disussion_pages]]",
|
|
and is currently available from [[smcv]]'s git repository on git.pseudorandom.co.uk (it's the
|
|
`postcomment` branch). A demo wiki with the plugin enabled is running at
|
|
<http://www.pseudorandom.co.uk/2008/ikiwiki/demo/>.
|
|
|
|
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]])

Wishlist:
|
|
|
|
* tbm would like anonymous people to be able to enter their name and possibly email
|
|
address
|
|
* smcv would like an indication of who you're posting as / the ability to log in
|
|
as someone else (even if anonymous comments are allowed, it'd be nice to be
|
|
able to choose to log in with a username or OpenID, like in Livejournal);
|
|
perhaps editpage needs this too
|
|
|
|
Fixed issues:
|
|
|
|
* Joey didn't think the `\[[!comments]]` directive was appropriate; comments now appear
|
|
on pages selected with a [[ikiwiki/pagespec]]
|
|
* Joey thought that raw HTML should always be allowed; it now is
