2013-08-14 Comments on this Wiki Blog

I’ve done a few changes. Let’s see whether it works out.

  1. when viewing ordinary pages, previous comments and the comment form are shown ← this is what I wanted to add
  2. people who follow the RSS feeds will therefore easily find the obvious comment form when following the link ← this is what I hope to achieve
  3. when leaving a comment, you end up on the comment page, which might be confusing
  4. when looking at RecentChanges, which has some extra magic associated with its name, the comments are not shown
  5. when looking at older revisions, the page history, and many other variants, the comments are not shown
  6. when looking at a journal page such as Diary, the comments are not shown
  7. when looking at a journal page such as Diary, you can still see links to inline the comment page
  8. inlined comment pages don’t come with an automatic comment form—you need to click on the “Add comment” link at the end
  9. comment pages are still excluded from the usual feeds (I wonder whether I should change this)

I think the Wiki + Blog combo still works. I’m just trying to make it less weird. :)

Source code for your config file, if you’re an Oddmuse user. The source code below also includes my Google +1 setup (Oddmuse:Google Plus One Module) because my code needs to avoid the situation where a page shows two +1 buttons. As for comments within journals, I use Oddmuse:Dynamic Comments Extension.

# Google +1 list

push(@MyAdminCode, sub {
       my ($id, $menuref, $restref) = @_;
       push(@$menuref, ScriptLink('action=plusone',
				  T('Google +1 Buttons'),

$Action{plusone} = \&DoPlusOne;

sub DoPlusOne {
  print GetHeader('', T('All Pages +1'), ''),
    $q->start_div({-class=>'content plusone'});
  print $q->p(T("This page lists the twenty last diary entries and their +1 buttons."));
  my @pages;
  foreach my $id (AllPagesList()) {
    push(@pages, $id) if $id =~ /^\d\d\d\d-\d\d-\d\d/;
  splice(@pages, 0, $#pages - 19); # last 20 items
  print "<ul>";
  foreach my $id (@pages) {
    my $url = ScriptUrl(UrlEncode($id));
    print $q->li(GetPageLink($id),
		qq{ <g:plusone href="$url"></g:plusone>});
  print "</ul>";
  print $q->end_div();
