I dont want kareha to fill out the name and link fields with cookie info, how do i fix this?

>>40
Open the .js file, and put a return; right before the var el in set_new_inputs.

>>41
Delete kareha.js.

>>42
Delete kareha.pl.

WAHa, I was just wondering why you use -size/-geometry in the ImageMagick command instead of -resize. The latter works much faster on my computer than the first. Just asking.

How do you change what the bullet statements below "password" say on the main board?

for example if i change what file types are allowed or file sizes or just want to post the rules there?

>>46
Edit include/rules.html.

>>47

yeah i tried that but it's not updating :/

I can't find where in the code it links to rules.html

>>49
Go to Manage and click Rebuild caches.

I'm trying to cobble together something similar to 4chan/tg/'s dice rolling function. If "dice XdY+Z" is in the email field when the post is submitted, the script will randomly generate numbers to simulate rolling X-number of Y-sided dice, add modifier Z, and put the result into the posted post. So "2d6+5" would result in something like

Rolled 4, 3 + 5 = 12
Rest of post derp herp blahblah etc

The perl script I've found is different in that it can process negative modifiers instead of just adding, but the basic idea is the same.

#!/usr/bin/perl -wl
use strict;
$_ = shift or die 'Invalid argument passed';
s/\s+//g;
/^(\d+)[dD](\d+)([+-]\d+)?$/ or die 'Invalid argument passed';
my $sum = 0;
$sum += 1 + int rand $2 for 1..$1;
$sum += $3 if defined $3;
print $sum;

The problem is I don't know anything about perl or coding aside from some basic concepts like variables and subroutines, so I don't know how to integrate the rolling script with Kareha.
I started off looking through kareha.pl to see where it called rotator.pl (banner image randomizer), so I could modify the function for my own purposes, and have had no luck. I'm probably looking for the wrong thing, or in the wrong place, or have seen exactly what I need but didn't recognize it...

Any help at all is appreciated.

>>51

> similar to 4chan

First ask yourself why you need to make a copy of something that already exists. And I can't figure out why you're bringing up banner images, either.

But disregarding that... try putting this in wakaba.pl, right after the message text formatting. You'll probably have to work with it because I didn't test this and I never get perl to work right on the first try. Also I don't remember what the variables are called offhand. Probably they're both wrong.

# mostly your same regex, except with the word 'dice'
# (and with /x, because cramped-up regexes are unreadable)
if ($link =~ /dice \s* (   # $1 = everything after 'dice'
             (\d+)         # $2 = old $1
             \s* d \s*     # the letter 'd', literally
             (\d+)         # $3 = old $2
             \s*           # some space!
             ([+-]\d+)?    # $4 = old $3, maybe
    )/xi) {
    # this is the same
    my $sum = 0;
    $sum += 1 + int rand $3 for 1..$2;
    $sum += $4 if defined $4;
    $message = '<p>Rolled ' + $1
             + ' = <strong>' + $sum + '</strong></p>'
             + $message;
}

And after you get it to work, maybe post the functioning code to the patch thread. (http://wakaba.c3.cx/sup/kareha.pl/1256252904/l50)

How do I stop the thread numbers from reseting to 1? Eg. "No.1"

>>53
Use Wakaba instead of Kareha.

There's probably ways to patch kareha to keep a running post count, but it'd be a deep change.

>>54

Thanks, but I have no idea on how to set up the sql database for Wakaba... If anyone could help me with that, I'd greatly appreciate it.

>>55
You don't have to set anything up. Wakaba does that for you. All you do is fill out the server/username/password in the config, which your host should have given you.

Or you could also try uncommenting the second SQL_DBI_SOURCE line (the one that says "SQLite") instead, and leave everything else blank, if you have the perl sqlite module installed.

All the transparent PNGs I upload get a white background. Where can I disable this?

>>57

"Disable" it how? Thumbnails are JPEGs, they can't be transparent. It has to be SOME colour.

>>58
Well is there a way to create the thumbnails in the original format then? I've seen transparent PNG thumbnails and even transparent, animated thumbnails on various chans.

>>59
Of course it's possible, if you rewrite the thumbnail-making code.

use constant DISPLAY_ID => 'day'; # How to display user IDs (0 or '': don't display,

IDs don't seem to be changing daily. Am I doing something wrong here?

Whenever I make a post that has any space between lines, the blank line doesn't show up in the Photon theme. Does anyone know what I need to modify to get Photon to recognize the double-space?

Left is Photon, right is Burichan

>>62
Seek and destroy this rule:

blockquote p {
        margin: 0;
        padding: 0;
}

Bump for some help with >>61

Seriously. If I'm doing something stupid, just say so. Otherwise, I could really use some help as this seems to be broken.

So there was talk of using a sage checkbox instead of having a link box...
http://wakaba.c3.cx/sup/kareha.pl/1141929669/657
Did anyone ever try that? I'm using an anonymous board where that's the only use for the link box. Kinda awkward.
Also, the mailto:sage thing is silly. Only sage posts turn the name into a mailto link, and that doesn't do anything useful.

Any particular reason why Wakaba stores the IP of posters as an integer?

>>67 That's the only portable way to compare addresses and deal with CIDR ranges.

>>65
Yeah, I've done this on my boards for some time now. Though, we kept the ability to also put sage into the email field, since not everyone is intelligent enough to notice the checkbox. It works well.

>>69
Did you make it so sageing doesn't add a mailto link, or just add a checkbox option? I was thinking of changing this line in kareha.pl:

$link="mailto:$link" if $link and $link!~/^$protocol_re/;

so that there's another condition that $link not be "sage", but I'm not sure if that will break the sage function.

Hello man,

I have accidently moved a couple of threads to archive. How to return them to an imageboards from archive? Simply copying files from /src/, /res/, /thumbs/ doesnt help - e.g., in /res/ html files of threads even disappear after cache update! How to revive threads from archive?

>>71
You can't.

>>72
no T_T

How can I add transparency to previews of the pictures on my wakaba board?
Some of the full image has transparency, but previews never have.

>>74
You need to modify the code to write previews as something other than jpg.

>>75

could you help me? Or where can I find info? I want the png and gif images to keep their transparency even in previews.

Hello everyone,

I have a trouble - oekaki applet doesnt work. I can draw normally, uplaod the picture, but after that it says "management password incorrect". Regular posts are sent normally. Why management password incorrect? Maybe wakaba encodes management password incorrect due to encoding? I have utf-8 installed

Lol, problem solved, dunno how
77-kun

How can I get this USER WAS BANNED FOR THIS POST message on Wakaba?

>>79

You can't. That's a feature.

I've setup my board, and every thing is working. But the board look itself is odd.
The favicon does not show up, and the text font is different in most places. places is a deferent font than the install of Kareha at The Society for the Study of Imageboard Culture. Even in the input boxes. In fact as I was typing this I noticed that mine is actually like this board here. Why is text on The Society for the Study of Imageboard Culture look different from this board here and mine?

>>81
Because The Society for the Study of Modern Imageboard Culture uses SHIFT_JIS encoding (which you should avoid, unless you're Japanese or a huge weeaboo).

>>82
Oh I understand. You say I should avoid it though The Society for the Study of Modern Imageboard Culture does not seem to have any problems with it. What would be the disadvantages of using SHIFT_JIS?

>>83
Unicode characters won't work. You should rather use a bit of CSS if you absolutely must have the Japanese fonts.

So...

10 pages worth of threads for my Kareha image board disappeared a couple of days ago, and I wanna know why. I haven't touched anything in the FTP files in months.

Could anyone explain why this happened and how to get them back/prevent it from happening?

>>85
Maybe somebody guessed your admin password?

No, that's not it. After conducting an experiment, it seems like the pages are only able to be at 0 and 1 from now on. It can't make a page 2 anymore for some reason.

Maybe i should just reinstall it?

So, where do I get this url shortening decoder for Wakaba?

I am running small Kareha board. Somehow one thread got disappeared I don't know how. Limits are disabled (manually of by default) or set to other values, so threads shouldn't be autodeleted, I think.
There were 5 pages, and that thread was on 0 page (though it was old, but most active, post limit and bump limit was not reached). OP didn't deleted it too. Where could be the problem?
Also, TRIM_METHOD is better to set to 1? Maybe because of this that thread was gone.

I keep getting this error not matter what I do. Advice?

No SQL settings defined in the configuration at config_defaults.pl line 11.
BEGIN failed--compilation aborted at config_defaults.pl line 126.
Compilation failed in require at wakaba.pl line 17.
BEGIN failed--compilation aborted at wakaba.pl line 17.

To continue about >>89
Could it be because of no space left on disk and that thread was bumped (posted in it)?

I have a small question regarding the the "posts omitted" message in Wakaba. Is there any possible way to accomplish what I'm showing on the bottom half of this image?

http://i.imgur.com/IljHR.png

>>92
Yes, you can misspell "omitted" by editing strings_en.pl.

>>96
Doesn't really solve my problem, but okay.

Hi,
I'm using lighttpd and perl on a openwrt.
I'm getting the following error if I'm posting anything:

---
Software error:
Attempt to reload Encode.pm aborted.
Compilation failed in require at wakautils.pl line 616.

---

The Section is creating something for a cookie. How can I fix his?

>>99

Don't use lighttpd, probably. I don't think anyone's managed to get wakaba to work with it.

It's working on my debian box with lighttpd.

>>100
I actually have it running perfectly on my Debian box as well.

http://glauchan.ax.lt/

>>100
The kei.iichan.net boards use it, apparently.

>>99

I believe this problem have something to do with the used perl version for openwrt.
I only installed the "missing" packages, but maybe I missed a few.

It isn't possible to install all perl packages at all, because there is not enough space left on the device

>>90
Help please?

>>105

Well did you define any SQL settings?

>>106
Only the bare minimum ones needed to run and connect to the database.

>>107

Well, better check that again, then. Remember not to comment it out, either.

Trying to set up a Kareha board, however, I've noticed that unless I delete kareha.pl, re-upload it and run it no changes take effect. Is this normal, or am I missing out on something?

>>109
Rebuild the caches from the admin panel after you make changes.

Well I got it working.
Sort of.
http://chansoft.heliohost.org/demos/wakaba/wakaba.html

>>110

I'm guessing it depends on the host's control panel, but just how would I do that?

>>112

Go to admin.pl.

wAHA, what do you think of youtube embedding in the post? Some users want it but I find it annoying when they just start posting a lot of embedded videos instead of images, or text, or at least links.

Would anyone mind telling me if i should be using the same cryptographic secret key across all boards?

>>115

If you want secure tripcodes to be the same across all boards, yes.

I get a 404 when I try to Preview Post using Opera (11.51). Does anyone else have this problem?

>>99

Got the Page-Load Problem solved. It was missing .pm file.

CGI::Carp qw ( fatalstobrowser does not work correctly on lighttpd.

use the following lines instead:

-> kareha.pl

#use CGI::Carp qw(fatalsToBrowser);

BEGIN {
use CGI::Carp qw ( carpout);
open ( LOG, ">>/tmp/cgi.log" ) or die ("Unable to open cgi.log");
carpout (LOG);
}

So you'll find the perl errors in /tmp/cgi.log

Anyone an idea to solve the problem, that I only see the new posts with a "refresh" of the page .. with lighttpd ??

Hi,

I am using wakaba 3.0.8, apache/2.2.21 and mysql 5.1.56.
Although the site is accessible, I can't post anything. The site just loads for about a second when i use the Submitbutton. There are no errors in the Apache or mysql logs. Any help would be appreciated.

>>119

>Anyone an idea to solve the problem, that I only see the new posts with a "refresh" of the page .. with lighttpd ??

I'm having this same exact problem with Wakaba (and maybe Kareha; too early to tell). Any solutions?

>>121
Configure lighttpd to serve HTML files with an "Expires" header set to a date in the past.

>>120

Rebuild caches.

Has anyone here ever tried to port Kareha/Wakaba into php-based framework app?

Hi, I'm trying use Kareha in image mode, but keeping the textboard look, basically what this board is doing. I've setup kareha in text mode and image mode before, but how I set it up in imageboard mode and make it keep the textboard mode look?
The same thing is done on this board: http://www.secchan.net/niche/

>>127
set it up in textboard mode, then enable image posting in config.pl.

So I setup Wakaba on my hosts server and everything was working except for thumbnail generation. In place of the thumbnail you would see a dotted borderlined square, and in it is simple the words "No thumbnail." You click in and it opens the image just fine, but there is never any thumbnail.
Now, I just setup Kareha on the server in image mode, and the very same thing is happening. A dotted boarderlined square with the words "No thumbnail" inside it. And clicking the words brings up the image just fine. But neither will create thumbnails.
Is there anything that could cause this very same problem with both Kareha and Wakaba? I've tried what I could and now I'm stumped.

Help please?

My host uses Apache 2.2.17, by the way.

>>129
Get your host to install Imagemagick (the command line version).

>>129
Kareha and Wakaba need an external program to work? Lame. Well it can't be helped.
But, if I am unable to get them to install it, is there a workaround?

A BIG Thanks :)

>>131
get an imagemagick binary that will run on your server, put it on the server, and set the location in config.pl.

Hey guys, I'm trying to add spoiler text support to wakaba, and I'm new to perl so this is a lot harder for me than it should be. Is there any reason why adding the following to `sub do_wakabamark($;$$)' is not working?

elsif(/^\[spoiler\]/) # spoilers{
    if ($lines[0]=~/^\[spoiler\](.*)/){
        while !($lines[0]=~/\[\/spoiler\]$/){
            push @spoiler,$1; shift @lines;
        }
    }
    $res.="<span class='spoiler'>".(join "<br />",@spoiler)."</span>";
}

Thanks in advance!!

>>135
Oh and if it matters, I'm getting a regex error in this section for some reason, and I don't understand what that has to do with my changes:

# do ^H
if($]>5.007)
{
    my $regexp;
    $regexp=qr/(?:&#?[0-9a-zA-Z]+;|[^&<>])(?<!\^H)(??{$regexp})?\^H/;
    $line=~s{($regexp)}{"<del>".(substr $1,0,(length $1)/3)."</del>"}gex;
}

>>135

>elsif(/^\[spoiler\]/) # spoilers{

There's supposed to be a linebreak before the {.

>>135
>>136
>>138
Made a bunch of changes and got it working for the most part, but now I can't make the spoilers work if post contains any other text before or after the tags. Here's what I have:

	elsif(/.*\[spoiler\].*/) # spoilers
	{
		my @spoiler;
		if ($lines[0]=~/.*\[spoiler\](.*)/){
			shift @lines;
			while ($lines[0]!~/\[\/spoiler\]$/){
				push @spoiler,$lines[0]; shift @lines;
			}
			shift @lines;
			if ($lines[0]=~/\[\/spoiler\]$/){
				$lines[0]="";
			}
		}
		$res.="<span class='spoiler'>".(join "<br />",@spoiler)."</span>";
	}

Not sure what to do next...

Okay, so I moved it until after WakabaMark finishes messing with the text, and did my best to work around the strange placement of the tags it introduced. Here's my "final" solution (until I get rid of Wakabamark completely and start from scrath):

if($res=~/.*\[spoiler\].*/){
	$res=~s/\[spoiler\]*/\<span class\=\'spoiler\'\>/g;
	$res=~s/\[\/spoiler\]*/\<\/span\>/g;
	$res=~s/\<p\>/ /g;
	$res=~s/\<\/p\>/\<br \/\>\<br \/\>/g;
	$res=~s/\<br \/>/ /;
	$res=~s/\<\/span\>\<br \/\>\<br \/\>/\<\/span\>/g;
}

>>140

Protip: Don't do that. It seems like it's easy to write a simple text formatter using a bunch of chained regexes.

It is not.

Every single regex is going to interact with every other regex, in subtle ways you will not predict, and you will open yourself up to mis-formatting and HTML injections. Hunting these down will be painful, and once you are done (which you never really are) you will have an utterly unmaintainable monster.

If you want write a text formatter, you will need to use some kind or other of actual parser.
