Simple Fast Highlighter

Usage

Wordpress plugin

Download the plugin manually from the Wordpress plugin directory or from within the Wordpress admin.

After activating it, you'll see a formats select box and a code button appear in the toolbar of the editor.

Standalone

• Download the script, language file and stylesheet and add these to your HTML file.
• Add the language classes to each PRE and CODE element you want to have highlighted. The classes are the keys of the Highlighter.Language object in the language file.
• Now just call Highlighter.init();

Extend

You can simply add other languages by extending the Highlighter.Language object. See the language file for examples.

Change style

There are 4 classes defined in the stylesheet. If you want to change the styles for all languages, just edit it in there or overrule them with your own css file.

If you want to have a different style for a specific language, just add the language class before the 4 highlight classes. For example to style PHP different:

.php span.sfhkeyword {
  color:blue;
  
.php span.sfhquote {
  color:green;
}

.php span.sfhcomment {
  color:gray;
}

.php span.sfhoperator {
  color:red;
}

Javascript

// A simple object copy function
var simpleCopy = function(src, dest) {
  for (var key in src) {
    dest[key] = src[key];
  }
  return dest;
};

var replaceEntities = function(s) {
  if (/\d+/.test(s) && /\w+/gi.test(s)) {
    console.log("Found it!");
  }
  return s.replace(/</g, "&amp;lt;");
  return s.replace(/hoi[\w]+/g, "-");
};
