+# [[MarceloMagallon]]'s implementation
+
I've been looking into this. I'd like to implement a "blogcomments"
plugin. Looking at the code, I think the way to go is to have a
formbuilder_setup hook that uses a different template instead of the
What I ended up doing is write something like this to the page:
- [[blogcomment from="""Username""" timestamp="""12345""" subject="""Some text""" text="""the text of the comment"""]]
+ [[!blogcomment from="""Username""" timestamp="""12345""" subject="""Some text""" text="""the text of the comment"""]]
+
+Each comment is processed to something like this:
+
+ <div>
+ <dl>
+ <dt>From</dt><dd>Username</dd>
+ <dt>Date</dt><dd>Date (needs fixing)</dd>
+ <dt>Subject</dt><dd>Subject text</dd>
+ </dl>
+
+ <p>Text of the comment...</p>
+ </div>
-Each comment is processed to a <div> with a <dt> and the text inside it. In this way the comments can be styled using CSS.
+. In this way the comments can be styled using CSS.

+# [[smcv]]'s implementation
+
+I've started a smcvpostcomment plugin (to be renamed to postcomment if people like it, but I'm namespacing it while it's still experimental) which I think more closely resembles what Joey was after. The code is cargo-culted from a mixture of editpage and inline's "make a blog post" support - it has to use a lot of semi-internal IkiWiki:: functions (both of those plugins do too). It doesn't fully work yet, but I'll try to get it into a state where it basically works and can be published in the next week or two.
+
+My approach is:
+
+* Comments are intended to be immutable after posting (so, only editable by direct committers), so they go on internal pages (*._comment); these internal pages are checked in to the RCS (although later I might make this optional)
+
+* ?do=smcvpostcomment (in the CGI script) gives a form that lets logged-in users (later, optionally also anonymous users) create a new comment
+
+* \[[!smcvpostcomment]] just inserts a "Post comment" button into the current page, which goes to ?do=smcvpostcomment - it's intended to be used in conjunction with an \[[!inline]] that will display the comments
+
+* The title (subject line), author and authorurl are set with \[[!meta]] directives, just like the way aggregate does it (which means I'll probably have to disallow the use of those \[[!meta]] directives in the body of the comment, to avoid spoofing - obviously, spoofing can be detected by looking at RecentChanges or gitweb, but the expectation for blog-style comments is that the metadata seen in the comment can be trusted)
+
+* The initial plan is to have comments hard-coded to be in Markdown, with further directives not allowed - I'll relax this when I've worked out what ought to be allowed!
+
+I've also updated Marcelo's code (above) to current ikiwiki, and moved it to a "marceloblogcomment" namespace - it's in the "marcelocomments" branch of my repository (see <http://git.debian.org/?p=users/smcv/ikiwiki.git;a=log;h=refs/heads/marcelocomments>). I had to reconstitute the .tmpl file, which Marcelo didn't post here.
+
+--[[smcv]]
+
+OK, the postcomment branch in my repository contains an implementation. What
+do you think so far? Known issues include:
+
+* The combination of RSS/Atom links and the "post new comment..." button is
+ ugly - I need a way to integrate the "new comment" button into the feed links
+ somehow, like the way inline embeds its own "new blog post..." feature
+ (I don't think the current way really scales, though)
+
+* There are some tweakables (whether to commit comments into the VCS, whether
+ wikilinks are allowed, whether directives are allowed) that are theoretically
+ configurable, but are currently hard-coded
+
+* The wikilink/directive disarming doesn't work unless you have
+ prefixdirectives set (which I just realised)
+
+* \[[!smcvpostcomment]] now displays the comments too, by invoking \[[!inline]]
+ with suitable parameters - but it does so in a very ugly way
+
+* Start-tags in a comment with no corresponding end-tag break page formatting
+ (unless htmltidy is enabled - inline and aggregate have the same problem)
+
+* There is no access control, so anonymous users can always comment, and so
+ can all logged-in users. Perhaps we need to extend canedit() to support
+ different types of edit? Or perhaps I should ignore canedit() and make the
+ access control configurable via a parameter to \[[!smcvpostcomment]]?
+ I'd like to be able to let anonymous (or at least non-admin) users comment
+ on existing pages, but not edit or create pages (but perhaps I'm being too
+ un-wikiish).
