HTML Handler


This is the development page for the HTML handler.
 


This handler generates "standalone" HTML, without the header/footer/menu items.

Dependency

None.

The code

Copy css/wikka.css to css/html.css, then add the following line to the top of html.css:

.header, .footer, .commentsheader, .copyright, .smallprint { display:none; }


Create handlers/page/html.php (version <=1.1.6.3) or handlers/html/html.php (version >=1.1.7):

<?php
if ($this->HasAccess("read") && $this->page) {
    // display page
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>
    <title><?php echo $this->GetPageTag(); ?></title>
    <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
    <style type="text/css">
    <?php include("css/html.css") ?>  
    </style>
</head>
<body>
<div id="content">
<?php
    $this->config['external_link_tail'] = '';
    print($this->Format($this->page["body"], "html"));
}
?>
</div>
</body>
</html>


Add the following after about line 1109 (version < 1.1.6.2) or line 1030 (version 1.1.6.2/1.1.6.3) in wikka.php (just before the final else statement):

        elseif ($this->method == "html")
        {
            print($this->Method($this->method));
        }


Add the code above after about line 2183 (version 1.2) in libs/Wakka.class.php (just before the final else statement).

Add the following after about line 2879 (version = 1.1.7) in libs/Wakka.class.php :

        // Handler to generate html
        elseif ($this->handler == 'html')
        {
            print($this->Handler($this->handler));
        }


The Wikka parsing engine doesn't differentiate between relative URIs and absolute URIs (the default is to prepend any "unidentified" URIs with http://). To enable relative URIs, copy formatters/wakka.php to formatters/html.php, then make the following changes starting at around line 240 (version < 1.1.6.2), line 284 (version 1.1.6.2/1.1.6.3), or line 527 (version >= 1.1.7):

        // forced links
        // \S : any character that is not a whitespace character
        // \s : any whitespace character
--->change start<---
        // Hack to pick up leading . and / characters in URI
        else if (preg_match("/^\[\[([\S|\.|\/]*)(\s+(.+))?\]\]$/s", $thing, $matches))      # recognize forced links across lines
        {
--->change end<---
            list (, $url, , $text) = $matches;
            if ($url)
            {
                //if ($url!=($url=(preg_replace("/@@|££||\[\[/","",$url))))$result="</span>";
                if (!$text) $text = $url;
                //$text=preg_replace("/@@|££|\[\[/","",$text);
--->change start<---
                $link = $wakka->Link($url, "", $text);
                // Hack to handle relative URIs (i.e., links to files
                // in the same directory)
                if(strstr($link, "http://.") || strstr($link, "http:///"))
                    $link = preg_replace("/^(.*)http:\/\/(.*)$/",
                                         "\${1}\${2}",
                                         $link);
                return $result.$link;
--->change end<---
            }


To disable the display of CamelWords and InterWiki as clickable links, also delete the following lines from formatters/html.php:

    "\b[A-Z???][A-Za-z???????]+[:](?![=_])\S*\b|".                                          
              # InterWiki link
    "\b([A-Z???]+[a-z????]+[A-Z0-9???][A-Za-z0-9???????]*)\b|".                            
              # CamelWords


Dumping an entire wiki

This is some proof-of-concept code I hacked together rather quickly for a Wikka user in need of a way to dump all of his Wikka pages to a directory. I've only tested this on version 1.1.6.0, so your results may vary. By default, html files are dumped in /tmp/wikka_test/.

<?php      
// Get list of all wiki pages on site
$pages = $this->LoadAllPages();
           
foreach($pages as $page)
{  
    if ($this->HasAccess("read") && $page) {
        // dump pages
        ob_start();
        ?>
        <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
        <html>
        <head>
            <title><?php echo $page['tag'] ?></title>
            <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
            <style type="text/css">
            <?php include("css/html.css") ?>
            </style>
        </head>
        <body>
        <?php
            $this->config['external_link_tail'] = '';
            print($this->Format($page['body'], "html"));
    }
    $buffer = ob_get_flush();
    $filename = $page['tag'].".html";
    file_put_contents("/tmp/wikka_test/".$filename, $buffer);
}
$this->Redirect();
?>
