Well, there are some issues to consider here:

• Hardly anybody needs to ever use fusianasan. It's a gimmick. Design decisions should not be made around it.
• The strings may be strange, and combining fields isn't the best design possible, but this is a 0ch clone, after all. If I were designing something from scratch, I'd do things differently, but as it is, people are expecting 0ch behaviour, and it would confuse them if the script worked like 0ch in some ways but not others.
• I might consider adding additional strings that trigger sage and fusianasan, but I'm not sure what they should be.

In the end, people actually enjoy the 0ch quirkiness. I know I do. I know about designing good interfaces, but there's something fun about an interface that is a little bit quirky, as long as it doesn't get in your way, and these things don't.

Well, both >>30 and >>31 didn't change the ¦ into ?U so I am out of ideas what happened...

Ah, there was an XHTML error in the cutesy capcode, and of Safari won't handle XHTML correctly and die on errors. Gah. Fixed.

Hey, I just noticed this: where did the admin link go? Or are you working on a separate interface already? :D

>>110
Happened to me, too, sometimes it goes black, sometimes it goes white. Screen reappears if you just scroll up a bit but it's still strange.

What browser are you using? I think I've tracked down the problem, and it's most likely a browser bug. The ancient Firebird (not fox, even) version I tested at work had the same bug (character set issues in the escape() and unescape() functions). It looks like your browser also doesn't follow the spec for how they are supposed to work.

The one with encoded Javascript that makes you post with fusianasan is cute.

By replacing it with AN EVEN DUMBER PUN!

> Right, I guess it was dumb to mention 0ch/Futaba in the first place. The point is, as you said yourself, tripcodes are a gimmick, and if someone wants to maintain a persistent identity across multiple boards and sites (ie, everyone here with a tripcode), they have no choice but to use ordinary tripcodes. Secure tripcodes are useless because they limit your identity to a single board, supposing each board/site's cipher key is different -- which it should be, since that's the point of having a secure tripcode in the first place. No one should be so paranoid about a tripcode that they'd need to have a different one per board/site.

True, they're of limited usefulness, but people like admins might prefer to use them. And there are certain cases were you might use them temporarily for various purposes. I wrote the code already, so I might as well leave it in. It has some uses at least.

> Shouldn't we sacrifice some backwards compatibility for a more robust and scalable design? It might even be possible to provide an upgrade.pl for old threads.

I think I'm too lazy to do it. It's kind of hairy. Besides, as I said, you can remove a lot of the drawbacks of seprate installations by using symlinks.

0ch-PHP had this nifty feature where if it was a certain "high bandwidth" time of day, then you couldn't view the whole thread.

Hm... that is kind of useless on a worldwide forum, huh?

But there should still be an option to keep people from viewing more than 100-200 posts, as an emergency way of saving bandwidth.

Kareha can't use different layouts for posts on different pages, except by CSS trickery. I could add the second colon, though.

Also, I've implemented optional thread closing now, but there's no extra post. That would just be a total mess to implement, and would make re-opening threads annoying, if such a feature was requested. It replaces the posting form with a notice that the thread has been closed, instead.

It's also more markup when even the existing one isn't working as well as it should.

If you want to have a look at what the code actually does to dig out flaws, here is the current version:

sub sanitize_html($%)
{
	my ($html,%tags)=@_;
	my (@stack,$clean);
	my $entity_re=qr/&(?!\#[0-9]+;|\#x[0-9a-fA-F]+;|amp;)/;

	while($html=~/(?:([^<]+)|<([^<>]*)>?)/g)
	{
		my ($text,$tag)=($1,$2);

		if($text)
		{
			$text=~s/$entity_re/&amp;/g;
			$text=~s/>/&gt;/g;
			$clean.=$text;
		}
		else
		{
			if($tag=~m!^\s*(/?)\s*([a-z0-9_:\-\.]+)(?:\s+(.*?)|)\s*(/?)\s*$!si)
			{
				my ($closing,$name,$args,$implicit)=($1,lc($2),$3,$4);

				if($tags{$name})
				{
					if($closing)
					{
						if(grep { $_ eq $name } @stack)
						{
							my $entry;

							do {
								$entry=pop @stack;
								$clean.="</$entry>";
							} until $entry eq $name;
						}
					}
					else
					{
						my %args;

						$args=~s/\s/ /sg;

						while($args=~/([a-z0-9_:\-\.]+)(?:\s*=\s*(?:'([^']*?)'|"([^"]*?)"|['"]?([^'" ]*))|)/gi)
						{
							my ($arg,$value)=(lc($1),defined($2)?$2:defined($3)?$3:$4);
							$value=$arg unless defined($value);

							my $type=$tags{$name}{args}{$arg};

							if($type)
							{
								my $passes=1;

								if($type=~/url/i) { $passes=0 unless $value=~/(?:^$protocol_re:|^[^:]+$)/ }
								if($type=~/number/i) { $passes=0 unless $value=~/^[0-9]+$/  }

								if($passes)
								{
									$value=~s/$entity_re/&amp;/g;

									if($value=~/"/) { $value="'$value'" }
									else { $value="\"$value\"" }

									$args{$arg}=$value;
								}
							}
						}

						my $cleanargs=join " ",map { "$_=$args{$_}" } keys %args;

						$implicit="/" if($tags{$name}{empty});

						push @stack,$name unless $implicit;

						$clean.="<$name";
						$clean.=" $cleanargs" if $cleanargs;
						$clean.=" $implicit" if $implicit;
						$clean.=">";
					}
				}
			}
		}
	}

	my $entry;
	while($entry=pop @stack) { $clean.="</$entry>" }

	return $clean;
}

All right, code updated again. This time, some experimenting! I've implemented a tentative system for changing markup types. This needs a bunch of testing, of course, so here's the test thread link once again: http://wakaba.c3.cx/sup/kareha.pl/1099697376/

Thoughts and comments are welcome. I'm still trying to figure out how exactly to do this.

There's a bunch of other changes and fixes too, so mention if anything breaks, as usual. Also, shift-reload!

>>344 orz

> Can't this be somewhere else but the post form?

No, because that would be immensely useless and annoying, because nobody would know it's there, and even if they did, they'd have to go somewhere else every time they wanted to post something using a different markup.

> forced fusianasan

that seems kind of evil.

Damn, I was about to plug >>96 when I saw you uploaded the new version. Thanks for listening WAHa, you're awesome. :D

(Does this work like rules.html in mode_image? Is the board title inserted automatically in templates.pl or is it part of that separate html file?)

Already a few nitpicks though: (1) index.html#menu and index.html#1 links should be automatically inserted to the right of the board title (or below if you're looking at it without CSS), and (2) the "Create new thread" title isn't really necessary, since the widget button already explains its function (like with the reply box).

Unrelated: in 2ch thread lists, position numbers are followed by colons, not periods.

PS: I just tested fusianasan + tripcode on 2ch, it works fine.

There are some inconsistencies in both the Blue Moon and Futaba styles, with regard to the size and formatting of text labels in the Create new thread and Reply form areas.
The spacing of the Create new thread title is off in Futaba, Headline, and Toothpaste.
None of the styles that utilize rounded corner borders have them in the Create new thread area.

"page top" is better imho

I am not >>208 but the first who suggested this here (long ago). I think it may be vital for future, actually popular boards to limit the filesize of a thread so that the board won't get hammered by repeated loads of whole threads without having to limit the size of posts themselves something fierce.

I have to disagree with this. It should run in perl too.

• If you're running wakaba, obviously perl must be there
• Most hosts that library-poor don't provide compilers (or shell) either
