- In the above example the "ini" formatter was selected, so the file formatters/ini.php was included.
- Within this script you have access to a variable $text, a string that contains the code, content of the block.
- Within the formatter process $text (mostly string manipulations) and print the result to stdout.
- note: the ";line-number" is for the moment only used in the GeSHi code.
- When you display a normal page, the default handlers/page/show.php handler will call at some point $this->Format($this->page["body"], "wakka") which includes the formatters/wakka.php code.
- Within formatters/wakka.php the %%(formatter[;line-number]) code %% is detected and
- In " else if (preg_match("/^%%(.*?)%%$/s", $thing, $matches)) " a new call to $wakka->Format($code, $language); is made.
- $language = "ini" in this example and $code is our content (and will become $text).
- preg_replace patterns in $text: formatters/ini.php
<?php
/**
* INI language file for Wikka highlighting (configuration file).
*/
$text =
htmlspecialchars($text, ENT_QUOTES
);
$text =
preg_replace("/([=,\|]+)/m",
"<span style=\"color:#4400DD\">\\1</span>",
$text);
$text =
preg_replace("/^([;#].+)$/m",
"<span style=\"color:#226622\">\\1</span>",
$text);
$text =
preg_replace("/([^\d\w#;:>])([;#].+)$/m",
"<span style=\"color:#226622\">\\2</span>",
$text);
$text =
preg_replace("/^(\[.*\])/m",
"<strong style=\"color:#AA0000;background:#EEE0CC\">\\1</strong>",
$text);
print "<pre>".
$text.
"</pre>";
?>
- Do something with every line in the block:
<?php
foreach(split("\n",
$text) as $n =>
$line){
if(preg_match("/^\s*$/",
$line)) continue;
// ignore empty lines
// process $line here...
}
?>
