HTMLAREA for Wakka

[Note: HTMLArea is now apparently a commercial product. The codebase that was the start of HTMLarea (and may have been opensourced) is now under the name Areaedit (see http://www.formvista.com/otherprojects/areaedit.html) - 19 Aug 05]

This is a patch for WakkaWiki coded by VictorManuelVarela.

WakkaWiki a lightweight WikiEngine powered by PHP and MySQL, and developed by Hendrik Mans and Carlo Zotman. Good job!

File: wakka-with-htmlarea.tgz

Note: You must set "default_handler" to "html" to run HTMLAREA in new pages.

Steps to use HTMLAREA in existing Wakka Wikis
1. Patching wakka.php
diff file for wakka.php:

"action_path" => "actions",
"handler_path" => "handlers",
+ "default_handler" => "page",

"header_action" => "header",
"footer_action" => "footer",

Explanation:

search the SavePage() function, add a new $handler param (with "page" default value) and add a line in SQL insert command: handler = '$handler'
search the Method function, modify ($handler = "page") to ($handler = $this->config["default_handler"]
search the $wakkaConfig default value, add ("default_handler" => "page",)

2. Adding html formatter

formatters/html.php:

<?php

// This may look a bit strange, but all possible formatting tags have to be in a single regular expression for this to work correctly. Yup!

if (!function_exists("wakka2callback"))
{
function wakka2callback($things)
{
$thing = $things[1];

global $wakka;

// forced links
if (preg_match("/^\[\[(\S*)(\s+(.+))?\]\]$/", $thing, $matches))
{
list (, $url, , $text) = $matches;
if ($url)
{
if (!$text) $text = $url;
return $wakka->Link($url, "", $text);
}
else
{
return "";
}
}
// events
else if (preg_match("/^\{\{(.*?)\}\}$/s", $thing, $matches))
{
if ($matches[1])
return $wakka->Action($matches[1]);
else
return "{{}}";
}
// interwiki links!
else if (preg_match("/^[A-Z,ÄÖÜ][A-Z,a-z,ÄÖÜ,ßäöü]+[:]([A-Z,a-z,0-9,ÄÖÜ,ßäöü]*)$/s", $thing))
{
return $wakka->Link($thing);
}
// wakka links!
else if (preg_match("/^[A-Z,ÄÖÜ][a-z,ßäöü]+[A-Z,0-9,ÄÖÜ][A-Z,a-z,0-9,ÄÖÜ,ßäöü]*$/s", $thing))
{
return $wakka->Link($thing);
}
// if we reach this point, it must have been an accident.
return $thing;
}
}

$text = str_replace("\r", "", $text);
$text = trim($text)."\n";
$text = preg_replace_callback(
"/(\[\[.*?\]\]|\b[a-z]+:\/\/\S+|\n\t+(-|[0-9,a-z,A-Z]+\))?|\{\{.*?\}\}|".
"\b[A-Z,ÄÖÜ][A-Z,a-z,ÄÖÜ,ßäöü]+[:]([A-Z,a-z,0-9,ÄÖÜ,ßäöü]*)\b|".
"\b([A-Z,ÄÖÜ][a-z,ßäöü]+[A-Z,0-9,ÄÖÜ][A-Z,a-z,0-9,ÄÖÜ,ßäöü]*)\b|".
"\n)/ms", "wakka2callback", $text);

// we're cutting the last 
$text = preg_replace("/ $/", "", trim($text));
print($text);
?>

Explanation:

delete all HTML related stuff to show html as is.
delete all Wiki related stuff (except WakkaLinks and WakkaActions)

3. Adding html handler

Copy handlers/page.dialog {
color: ButtonText;
background: ButtonFace;
}

.dialog .content { padding: 2px; }

.dialog, .dialog button, .dialog input, .dialog select, .dialog textarea, .dialog table {
font: 11px Tahoma,Verdana,sans-serif;
}

.dialog table { border-collapse: collapse; }

.dialog .title {
background: #008;
color: #ff8;
border-bottom: 1px solid #000;
padding: 1px 0px 2px 5px;
font-size: 12px;
font-weight: bold;
cursor: default;
}

.dialog .title .button {
float: right;
border: 1px solid #66a;
padding: 0px 1px 0px 2px;
margin-right: 1px;
color: #fff;
text-align: center;
}

.dialog .title .button-hilite { border-color: #88f; background: #44c; }

.dialog button {
width: 5em;
padding: 0px;
}

.dialog .buttonColor {
padding: 1px;
cursor: default;
border: 1px solid;
border-color: ButtonHighlight ButtonShadow ButtonShadow ButtonHighlight;
}

.dialog .buttonColor-hilite {
border-color: #000;
}

.dialog .buttonColor .chooser, .dialog .buttonColor .nocolor {
height: 0.6em;
border: 1px solid;
padding: 0px 1em;
border-color: ButtonShadow ButtonHighlight ButtonHighlight ButtonShadow;
}

.dialog .buttonColor .nocolor { padding: 0px; }
.dialog .buttonColor .nocolor-hilite { background-color: #fff; color: #f00; }

.dialog .label { text-align: right; width: 6em; }
.dialog .value input { width: 100%; }
.dialog .buttons { text-align: right; padding: 2px 4px 0px 4px; }

.dialog legend { font-weight: bold; }
.dialog fieldset table { margin: 2px 0px; }

.popupdiv {
border: 2px solid;
border-color: ButtonHighlight ButtonShadow ButtonShadow ButtonHighlight;
}

.popupwin {
padding: 0px;
margin: 0px;
}

.popupwin .title {
background: #fff;
color: #000;
font-weight: bold;
font-size: 120%;
padding: 3px 10px;
margin-bottom: 10px;
border-bottom: 1px solid black;
letter-spacing: 2px;
}
%%

6. Set your wakka.config.php

Set the new default_handler to "html" to activate HTMLAREA in new pages.
To change an existing page to HTML handler you must run the next query:

UPDATE wakka_pages
SET handler = 'html'
WHERE tag = 'ExistingPage' AND latest = 'Y'
