ikiwiki/doc/todo/comment_by_mail.mdwn

I would like to allow comments on ikiwiki pages without CGI.
I have in mind something like

  * Use a pagetemplate hook  
    in a plugin (DONE)
  * add a mailto: url to each page matching some pagespec
    (currently every page gets a comment footer)
  * this mailto url goes to an address identifying the page  (something like
    user-iki-FE653b@host.fqdn.tld).  (DONE)

    > of the page name in the email address? I'm thinking about something
    > like `wikiname+index@host` or `wikiname+todo+comment_by_mail@host`.
    > The basic transformation would be to call `titlepage($page)` (in the
    > C locale), followed by replacing "/" with "+" (since "/" is not
    > valid in mails). --[[Joey]]

  * on the mail receiving end, these messages are either deleted, or ran through
    a filter to be turned into blog posts.

    - I'm thinking about how the filter should work. Within a 
    mail client, or as a batch tool to scan a mailbox? How to    interact with version control, if at all?

  * the same plugin can check for comments on a particular page next time the wiki 
    is generated, and add a link. (more or less done)
    > If the filter just checks in the posts into revision control, the
    > post-commit hook would handle updating the wiki to include those

  * work in progress can be 

   - [cloned](http://pivot.cs.unb.ca/git/ikiperl.git), or 
   - [browsed](http://pivot.cs.unb.ca/git/?p=ikipostal.git;a=summary)
