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 ).
