Documentation: HTMLHandlerInfo.
1.1.7 patch: [[http://wush.net/trac/wikka/ticket/218]]>>This is the development page for the HTML handler.::c::
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:
%%(php)
.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)
HasAccess("read") && $this->page) {
// display page
?>
<?php echo $this->GetPageTag(); ?>
config['external_link_tail'] = '';
print($this->Format($this->page["body"], "html"));
}
?>
%%
Add the following after about line 1109 (//version < 1.1.6.2//) or line 1030 (//version 1.1.6.2/1.1.6.3//) in ##wikka.php## (just before the final else statement):
%%(php)
elseif ($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## :
%%(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//):
%%(php)
// 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="";
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:
%%(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)
LoadAllPages();
foreach($pages as $page)
{
if ($this->HasAccess("read") && $page) {
// dump pages
ob_start();
?>
<?php echo $page['tag'] ?>
config['external_link_tail'] = '';
print($this->Format($page['body'], "html"));
}
$buffer = ob_get_flush();
$filename = $page['tag'].".html";
file_put_contents("/tmp/wikka_test/".$filename, $buffer);
}
$this->Redirect();
?>
%%
===To Do===
- Provide option to exclude inline CSS (with option to display listing of CSS to save in separate file)
- Provide "raw" html (no html, head, body tags)
- Clean up kludge in wikka.php (there should be no need to modify this file to accomodate a new handler type)
- Convince DarTar to include this formatter in the next release so we can show ##""Exports HTML == yes""## in the ""WikkaWiki"" entry on [[http://www.wikimatrix.org WikiMatrix]]!
